Alcohol use among people living with HIV (PWH) has been increasingly recognized as an important component of HIV care. Transdiagnostic treatments, such as Acceptance and Commitment Therapy (ACT), that target core processes common to multiple mental health and substance-related problems, may be ideal in HIV treatment settings where psychological and behavioral health comorbidities are high. In advance of a randomized clinical trial (RCT), the overall objective of this study was to systematically adapt an ACT-based intervention originally developed for smoking cessation, into an ACT intervention for PWH who drink at hazardous levels. Consistent with the ADAPT-ITT model, the adaptation progressed systematically in several phases, which included structured team meetings, three focus group discussions with PWH (N = 13), and in-depth interviews with HIV providers (N = 10), and development of standardized operating procedures for interventionist training, supervision, and eventual RCT implementation. The procedures described here offer a template for transparent reporting on early phase behavioral RCTs.

The routine assessment and treatment of alcohol use among people living with HIV (PWH) has been increasingly recognized as an important component of HIV care. Sixty seven percent of PWH report using alcohol in the previous year, [1] 27-40% report drinking at hazardous levels (i.e., typically a score of ≥ 8 on the Alcohol Use Disorders Identification Test [AUDIT]), [1, 2] and ~ 30% meet criteria for alcohol use disorder [3] . Compared to those who abstain or drink relatively less, PWH who are hazardous drinkers experience a significant increase in risk for: mortality, [4] lack of viral suppression, [5, 6] less utilization of antiretroviral therapy (ART), [6, 7] and sub-optimal adherence to ART [8] . Hazardous alcohol consumption is thus a critical factor in HIV treatment that significantly contributes to poorer HIV treatment-related outcomes, and consequently increased risk for onward transmission [9] Alcohol Interventions for PWH There is a growing literature on randomized clinical trials (RCTs) of alcohol interventions for PWH, with several systematic reviews and meta-analyses published in the past ~ 10 years [10] [11] [12] [13] [14] . The results of these trials have been mixed, with few showing clinically and statistically significant effects on quantity and/or frequency of alcohol use maintained over time. For example, the most recent review published in 2019 included 21 RCTs, [14] the majority of which used motivational interviewing, brief behavioral intervention, Cognitive Behavioral Therapy (CBT), or a combination of these approaches. Efficacy was inconsistent across studies; while some isolated studies, especially motivational interviewing and CBT, showed significant effects on quantity and frequency of alcohol use, overall the magnitude of the effects were generally small, and effects, when present, were often not maintained over time. A 2017 meta-analysis of 21 RCTs had similar findings, revealing that while there was an overall, small effect for quantity of alcohol use (weighted mean effect size = 0.11) and heavy drinking (weighted mean effect size = 0. 24) , there were no significant differences between intervention and control groups on frequency of alcohol consumption [13] . Consistent with these mixed results, Madhombiro et al. (2019) recommended a shift in the literature towards "transdiagnostic interventions that target alcohol use, adherence, and [other] mental disorders" (p. 13) [14] . Indeed, the high levels of alcohol use observed among PWH tend to occur in conjunction with a high prevalence of other mental disorders. Prior year prevalence of any mood/anxiety disorder among PWH is as high as 67% [15, 16] and several studies have also indicated high levels of dual diagnosis, ranging from approximately 10% up to 63% of PWH meeting criteria for both a substance use disorder and another psychiatric disorder [16] .

Transdiagnostic treatments, such as Acceptance and Commitment Therapy (ACT), target core processes and maintaining mechanisms common to multiple mental health and substance-related problems, which may be ideal in treatment settings with high psychological and behavioral health comorbidities [17] . The goal of ACT in particular is to alter the function, rather than content, of difficult thoughts and feelings by enhancing mindfulness skills, clarifying core values, and increasing commitment to values-guided behavioral action plans [18, 19] . ACT interventions target experiential avoidance-i.e., repeated attempts to eliminate or avoid unwanted thoughts, emotions, memories and/or urges-a process that is theorized to underlie multiple forms of maladaptive behavior, including substance use [20, 21] . The alternative to experiential avoidance is acceptancethe active process of fully experiencing emotions, thoughts, memories and/or urges while still behaving effectively [21] . Mindfulness skills are used to increase acceptance of aversive internal experiences in the pursuit of valued outcomes [20, 21] . These skills culminate in the ability to accept uncomfortable private experiences as "transient psychological events," resulting in broad psychological symptom reduction [20] .

There is a rapidly growing literature in support of transdiagnostic treatments, [19] including ACT. For example, a recent review of the meta-analytic evidence on ACT identified 20 meta-analyses that were based on 133 studies and 12,477 participants [22] . Results showed that ACT was efficacious across a broad range of intervention targets, including depression, [23] [24] [25] [26] [27] [28] [29] [30] anxiety, [24] [25] [26] [28] [29] [30] [31] [32] chronic pain, [27, 29, 33] substance use, [34] [35] [36] eating disorders [37] , psychosis, [38] stress, [26, 30] somatic complaints, [34] physical conditions, [23] and transdiagnostic combinations of conditions [23, 31, 33, 39] with small to medium controlled effect sizes. Three meta-analyses also identified 17 unique RCTs that found ACT to be efficacious for smoking and other drug use [34] [35] [36] with preliminary evidence of efficacy for treatment of co-occurring substance use and affective disorders [18, [41] [42] [43] [44] [45] .

ACT has recently been identified as a promising treatment for AUD, although the literature is still in its infancy. Based on a recently published review, [46] and our own assessment of the literature, only three studies have assessed ACT as a treatment for alcohol use [44, 47, 48] (two others examined ACT as a treatment for AUD and comorbid depression and/ or distress, but did not measure the effect of the treatment on alcohol consumption) [45, 49] . While none of these studies were randomized trials, all provided preliminary evidence to suggest that ACT is a promising intervention for alcohol use and comorbid stress, anxiety, and/or trauma. Thekiso et al. (2015) conducted a pilot study of a group-based ACT intervention designed to enhance treatment as usual (TAU) for inpatients with AUD and either depression or bipolar disorder [37] . The ACT group received 4 weeks of daily (5 sessions/week) group ACT-based therapy, while TAU received 4 weeks of standard integrated inpatient treatment [37] . Patients in the ACT group reported a significantly higher cumulative abstinence duration (i.e., percentage of total number of days abstinent from alcohol during the past 90 days) at 6-months post intervention, as well as significantly lower symptoms of anxiety and depression. Harvey et al. (2017) compared the effects of a group-based ACT intervention on anger, stress, and alcohol-related difficulties for military personnel to a waitlist control group [38] . Patients in the intervention group received one week of daily (5 sessions in total) group ACT-based therapy. Relative to the waitlist control group, patients in the ACT group reported significantly reduced alcohol consumption (i.e., AUDIT-C total score), anger, perceived stress, and anxiety at 1-month post-treatment. Finally, Meyer et al. (2018) conducted an uncontrolled pilot study of an individual-based ACT intervention for outpatient veterans with co-occurring post-traumatic stress disorder (PTSD) and AUD [39] . Treatment consisted of 12-weekly individual outpatient sessions of ACT [39] . At 3-months post intervention, patients reported significant reductions in past 30-day total drinks and heavy drinking days, as well as significant reductions in depressive symptoms. One other study investigated the effects of a brief (3, 11-13 min phone calls) acceptancebased coping skills training on alcohol-related outcomes among individuals dually diagnosed with PTSD and AUD [50] . Participants were randomized to either acceptance skills, cognitive restructuring skills, or an attention-matched control, and results indicated that both coping skills significantly reduced drinking compared to a control condition, but did not differ from one another on drinking frequency at 5 week follow-up. While the literature on ACT as a treatment for alcohol use is promising, none of these studies were conducted with PWH and none formally examined efficacy with a full-scale RCT.

The literature on ACT for other substance use is more well-developed, especially in the area of smoking cessation [51] . The brief format, innovative telephone, web-based, and smartphone-based platforms, and high comorbid psychiatric and medical conditions of the populations included in these studies provide a useful template for the development of ACT interventions for PWH who drink at hazardous levels [41] . More specifically, Bricker and colleagues recently completed a pilot RCT of a brief, 5-session, telephone-delivered ACT intervention for smoking cessation (The TALK Intervention), and compared it to standard CBT (matched for length and intensity) [41] . In this trial, quit rates at 6 months post randomization for participants who screened positive for depressive symptoms at baseline were 33% in the ACT condition compared to 13% in the CBT condition (OR = 1.2; 95% CI = 1.0-1.6); and were even higher among participants scoring low on acceptance of cravings at baseline (37% vs 10%; OR = 5.3; 95% CI: 1. [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] . The availability of ACT in this brief, manualized, telephone-delivered format makes it an ideal framework from which to adapt a treatment capable of addressing the multiple needs of PWH who are hazardous drinkers.

The overall objective of this study was to systematically adapt Bricker et al.,'s TALK intervention [40] for PWH who drink at hazardous levels-hereafter, referred to as the ACCEPT intervention-in advance of a pilot, and eventual full-scale, RCT. The Centers for Disease Control and Prevention (CDC) defines intervention adaptation as: "the process of modifying key characteristics of an intervention, recommended activities and delivery methods, without competing with or contradicting the core elements, theory, and internal logic of the intervention thought most likely to produce the intervention's main effects" [52] . While it has become more common in the behavioral HIV intervention and substance use treatment literature to describe pilot RCTs and other preliminary studies in advance of full-scale efficacy trials, what is less common is a comprehensive description of the process by which a treatment is developed and/or adapted. In an effort to increase transparency and rigor in the behavioral RCT literature, several models (e.g., the ORBIT model [53] , the Stage Model [54] , the ADAPT-ITT model [55] ) have been developed to guide early phase studies, which include intervention development and adaptation. The ADAPT-ITT [55] model is particularly relevant to our study, as it was specifically designed to provide a theoretical framework for systematically adapting evidence-based HIV interventions [55] . Consistent with the ADAPT-ITT [55] model, the formative work for the ACCEPT intervention progressed systematically in several phases, which included structured team meetings, focus group discussions (FGDs) with PWH who drink at hazardous levels, in-depth interviews with HIV clinic providers, and development of standardized operating procedures for interventionist training, supervision, and RCT implementation. Our goal in describing this process is to offer a model for other behavioral interventions to replicate in the reporting on early phase studies.

The adaptation of Bricker et al.'s TALK intervention [41] into the ACCEPT intervention, occurred in several phases guided by the ADAPT-ITT model (see Table 1 ) [55] . We describe next the process by which we chose the TALK intervention (Steps 1-2), determined what in the TALK intervention needed to be adapted and how (Step 3), documented changes to the TALK intervention manual and produced a draft of what would become the manual for the ACCEPT intervention (Step 4), involved key stakeholders to solicit feedback on the first draft of the ACCEPT intervention manual (Step 5), integrated suggestions from key stakeholders into a final ACCEPT intervention manual (Step 6), trained interventionists on the ACCEPT manual (Step 7), and developed and implemented procedures for a pilot RCT to test the feasibility and acceptability of the ACCEPT intervention (Step 8). We emphasize Steps 3-8 in this manuscript, as the formative work in Steps 1-2 has been previously described and published [56] . Our multidisciplinary team included two licensed clinical psychologists specializing in alcohol interventions and behavioral aspects of HIV treatment and prevention (SWK, SAM), one licensed clinical psychologist specializing in smoking cessation and ACT (JB), an epidemiologist specializing in alcohol and 

As described in the introduction, the research team systematically reviewed the literature on transdiagnostic treatments for people in medical settings who use alcohol and other substances and have a high prevalence of psychological and behavioral comorbidities. The large literature supporting ACT's efficacy contributed to it emerging as the core intervention of choice. Additionally, a brief, telephone delivered version of ACT had previously shown preliminary efficacy for smoking cessation [41] , which seemed ideal for adaptation to an HIV treatment setting. Finally, ACT's focus on value-driven behavioral action plans, and tools for managing automatic behaviors, particularly substance use, that result from an inability to cope effectively with negative emotion, mapped onto mechanisms (e.g., avoidant coping, substance use to cope) for poor HIV treatment related outcomes identified in the literature [57] [58] [59] . Indeed, ACT is designed to build skills that increase capacity for acceptance of difficult thoughts and feelings, rather than avoidance. Prior to officially moving forward with adaptation of the TALK intervention, we published preliminary data on the feasibility and acceptability of ACT as a treatment for PWH who are hazardous drinkers [56] . Briefly, 25 PWH participated in individual interviews designed to expose participants to the ACT model via three experiential exercises that represented the central principles of ACT (i.e., contacting the present moment, acceptance, and values-clarification). After each activity, participants were probed for their reactions and feedback. Overall, the qualitative interviews indicated that the activities were highly acceptable and feasible to PWH who are hazardous drinkers. As one participant explained: "Well I think that in this case it could be very helpful. Because people that you know that have HIV go through many different traumas you know it's hard to... it was very difficult for me to accept or whatever. And then you think you're gonna die or whatever... So these kind of activities could help people deviate from those thoughts and help them you know nurture themselves, help them see the great in them, you know not just the negative. And again acceptance and self-love that we all need, but especially with HIV positive people" (p. 9) [56] .

The Co-PIs (SWK and SAM) led the team of graduate students in an initial session-by-session adaptation of the TALK manual, spending approximately 1-2 h per session suggesting changes to the intervention content to be more consistent with targeting alcohol use among PWH. Adaptation of each session was followed by a broader team meeting with the co-investigators to discuss the proposed changes, solicit feedback, and integrate additional suggestions from the team (see Step 4) . The primary changes at this stage were related to: (1) shifting from an abstinencebased approach to a harm reduction approach, and assuming variability in motivation to change, rather than a desire to initiate a quit attempt [60] . Consistent with this shift, the manual was modified to include a committed action plan at the end of each session that was tailored to the participant's readiness for change. For example, the plan could focus on "thinking about changing alcohol use" or could include a specific drinking goal related to quantity and/or frequency (e.g., reducing the number of drinking days and/or number of drinks per drinking day). (2) In the sections designed to increase awareness of substance use behavior and motivation for change, we modified language describing "triggers" for smoking to focus on the "ABCs"-antecedents, behaviors, and consequences-of drinking behavior. We also replaced the word "trigger" with "internal/external events that tend to precede heavier drinking." Our decision to eliminate the use of the word "trigger" was based on the immediacy the term conveys, which, in our opinion was more consistent with smoking events, and less consistent with drinking events (3) Referencing resources and guidelines published by the CDC and National Institute on Alcohol Abuse and Alcoholism (NIAAA), we added an educational section on alcohol (e.g., definition of a standard drink, at-risk vs lower-risk drinking), HIV (e.g., definition of undetectable viral load, description of CD4 cells), and the association between alcohol and HIV (e.g., alcohol-associated non-adherence to ART), (4) Consistent with the behavioral alcohol intervention literature, we also added an expanded educational section to the final call that described the natural course of behavior change (i.e., not linear, characterized by steps forward and back). We emphasized this in the final intervention session in order to prepare the participant for inevitable setbacks as they continued to try and maintain changes to their alcohol use [61] . (5) Finally, we created a table for the interventionists that organized each session to include a check-in from the prior week, a review of self-monitoring data, a metaphor designed to introduce an ACT concept (e.g., values, defusion), and an experiential exercise to introduce a new ACT skill. We also added psychoeducation about each new ACT concept as well as a harm-reduction based action plan to set a SMART goal related to alcohol use and the practice of ACT skills. Once the first round of modifications was complete, the revised treatment manual-hereafter referred to as the ACCEPT manual-was ready for distribution to the study team, and the study progressed to Step 4.

SWK and SAM led the team in a session-by-session review of the new ACCEPTv1 intervention manual to solicit feedback on the first round of modifications. The full study team received each session of the ACCEPTv1 manual with modifications to the TALK intervention summarized in a written summary of the major changes described above. Team members submitted written feedback via email, which was supplemented with verbal discussion at team meetings (conducted via Zoom). This process was repeated until all five sessions of the ACCEPTv1 manual developed in Step 3 were reviewed by all members of the study team. The feedback was collated, and several additional substantive changes were incorporated: (1) In response to feedback that the first session was potentially too long and dense, given that we had added education on alcohol and HIV, the intervention was expanded to six sessions, splitting session one into two separate phone calls; (2) the educational component of session one was modified to include information about contemporary public health messaging related to HIV treatment and transmission (i.e., Undetectable = Untransmissible; Treatment as Prevention); (3) the language in the ACCEPTv1 treatment manual and workbook was modified to ensure it was at an 8 th grade reading level in order to accommodate literacy concerns. (4) an expanded educational section on creative hopelessness, and how it relates to alcohol use, was added to reinforce understanding of alcohol use as a strategy for engaging in experiential avoidance; (5) the phrase "uncomfortable thoughts, feelings, and situations that you tend to have before you drink heavily" replaced "internal/ external events" as an alternative to the word "triggers." A new intervention manual (ACCEPTv2) was drafted based on all the suggestions/changes from the study team and the adaptation process moved on to Step 5.

A semi-structured interview guide was used to demonstrate core concepts from the adapted ACCEPTv2 manual and assess receptivity, suggestions for improvement, and relevance to PWH who are hazardous drinkers. We conducted three focus group discussions (FGDs) with PWH (N = 13) and 10 in-depth interviews (IDIs) with HIV treatment providers (N = 10). The average age of the PWH who participated in the FGDs was 50.5 years (SD = 12.3, range: 33-68), and all reported hazardous alcohol use on the AUDIT-C (score ≥ 4 for men or ≥ 3 for women) [62] . Three participants identified as cis-gender women and 10 identified as cis-gender men; approximately half (53.8%) of the FGD participants identified as homosexual/gay/queer, 23.0% identified as heterosexual/straight, and 15.4% identified as bisexual. The majority (77%) of the participants identified as Black and the average number of years living with HIV was 18.8 years (SD = 11.77). One third (30.7%) of participants reported an income of less than $10,000/year, 30.7% reported an income between $10,000-$19,999/year, and 23.0% of participants reported an income between $20,000-$29,999/year. The average education level across participants was a high school graduate or GED (53.8%). Of the 10 HIV clinic providers, 70% were White, 80% were women, and the mean age was 40.2 (SD = 15.6, range: 24-55). Providers represented a variety of professional backgrounds including registered nurses, nurse practitioners, psychotherapists, and peer support leaders. Providers had an average of 6.4 years (range: 2-12) of experience working with PWH.

The FGDs and IDIs were conducted in a clinical research space adjacent to (0.25 miles) the local infectious disease clinic from which participants were recruited. The clinic provides outpatient and inpatient medical care for PWH from the 15-county Central New York area with an active outpatient census of approximately 1200 PWH. While located in a mid-size city, the geographic area served by the clinic includes urban, suburban, and rural populations. For this study, PWH were either recruited in-person or via a database of people who had formally participated in our studies and indicated an interest in additional research opportunities. For those recruited in-person, a graduate student research assistant assigned to recruit at the HIV clinic that day would enter the exam room before or after the patient's visit with their provider, explain the purpose of the study, and, if appropriate, collect the participant's contact information. Formal screening was done via phone and again once the participant presented to the lab for the FGD. Providers were recruited from word-of-mouth (e.g., a provider who participated would suggest another) and via direct contact from the graduate research assistant. For those recruited from previous studies, the database included men who have sex with men (MSM) living with HIV who reported regular alcohol consumption. Former participants were contacted via telephone and informed about the opportunity to participate in a new study, and if interest was communicated, a formal screening was conducted. For participants who were eligible and scheduled to attend a FGD, informed consent and permission to audio record was obtained immediately upon arrival at our lab. Subsequently, two graduate students (MF & JF) in a clinical psychology PhD program conducted roleplays of intervention content to demonstrate core concepts and exercises included in the ACCEPTv2 manual. Specifically, the interventionists demonstrated: (1) the overall goal of the ACCEPT study by asking participants to imagine the program as a car journey, with the participant in the driver seat, the interventionist in the passenger seat, and the participant's baggage (i.e., all the reasons that lead people to drink) in the trunk (Car Journey metaphor); (2) the section of the manual that provided education about alcohol use (e.g., what are safe drinking limits, what is a standard drink), HIV (e.g., what is viral load), and the relationship between them (e.g., how does alcohol use impact ART adherence); (3) the section of the manual describing values and committed action in which participants are asked to create a fantasy of their ideal 80 th birthday celebration and imagine someone they care about making a brief speech about what the participant stood for in life, and (4) acceptance, by asking participants to imagine being stuck in quicksand and, instead of trying to get out, dropping the struggle, laying back, and allowing their body to naturally come to the surface (Quicksand metaphor). After each section, participants were asked to provide feedback via structed open-ended questions such as: "What did you think about the Car Journey story as an explanation for the overall goal of the program?"; "What do you think about the alcohol/HIV education section? What could we do to make it easier to understand?"; "What are your thoughts about using the Quicksand metaphor to demonstrate 'dropping the struggle'?"; "What is your overall opinion about this intervention? How would the skills taught in this session be applicable to the lives of PWH who consume alcohol?" We also probed for information regarding issues that were raised during Step 3 related to the use of approachable language (e.g., the appropriateness of the term "antecedents", referring to the treatment as an "intervention") and reactions to study branding (e.g., logo for the study).

All de-identified audio files were uploaded to a secure, password-protected server immediately after IDI or FGD completion and subsequently deleted from the recording device. All FGDs and IDIs were transcribed by a professional transcriptionist, double checked for accuracy, and subsequently uploaded into Dedoose-a secure, cloud-based qualitative data analysis software program (https:// www. dedoo se. com/). Thematic analysis was used to analyze the qualitative data [63] . SWK and two graduate students (MF and JF) independently read all of the transcripts and met weekly to discuss emerging themes. At the descriptive level, analyses involved identifying and summarizing preliminary themes related to acceptability, relevance, and improvement of the adapted intervention. We developed a list of preliminary thematic content codes and child codes, agreed on definitions for each, and coded one transcript in Dedoose with the preliminary code book. We met again as a team to compare coding, resolve discrepancies, and refine definitions of parent and child codes. Consensus in coding was built when two of the three coders were in 100% agreement, and any discrepancy among coders was resolved with discussion. Once we achieved consensus in coding, the final codebook was uploaded to Dedoose, all transcripts were double coded, and the coding team continued to meet weekly for ongoing discussion. Illustrative quotes were chosen for overall representativeness of the central and/or sub-themes.

Results of the qualitative data analysis from the PWH who participated in the FGDs, and the providers who participated in the IDIs, are presented in Table 2 . The FGDs lasted approximately 120 min each, and the IDIs ranged from 45 to 70 min. Findings from the three FGDs and ten IDIs were organized into three major themes within each of the assessed intervention exercises: (1) general satisfaction, (2) areas of concern, and (3) suggestions for improvement.

Overall, HIV patients and providers reported high satisfaction with the content and skills depicted in the ACT exercises. Participants expressed an interest in the utility of the program for this patient population and reported that the acceptance and values-clarification exercises (i.e., 80 th birthday exercise, Quicksand metaphor) in particular were highly promising, could be valuable for PWH who are hazardous drinkers, and were feasible to implement. A majority of participants emphasized the universality of the core premises of ACT, while noting that PWH may uniquely benefit from the acceptance skills demonstrated in ACT, especially with regard to managing co-morbid health conditions. Although most HIV patients and providers endorsed high satisfaction with the intervention content, some minor areas of concern about intervention content, format, and modality were identified.

concerns regarding the length of the first session and lack of rapport-building. More specifically, they noted that the telephone-based modality may lead participants to become disengaged more quickly than an in-person intervention. HIV patients also noted that the language used to describe key concepts, such as "antecedents," was not appropriate for the target demographic, and HIV providers reported that the intervention workbook was not written at an appropriate literacy level for this patient population. 3. Suggestions for Improvement: With respect to suggestions for improvement, it was recommended by patients and providers that we incorporate greater rapport-building and more frequent in-session "check-ins" to increase participant engagement and better sustain attention via the telephone. Another suggestion was to substitute academic jargon (e.g., "antecedents") with more colloquial terms (e.g., "any thoughts, feelings or situations"). Participants also recommended that intervention exercises be better tailored to PWH. For example, some HIV patients noted that it may be challenging for PWH to fantasize about an 80 th birthday due to their HIV status and other health-related comorbidities. Given the prevalence of mental and physical comorbidities among PWH, both HIV patients and providers suggested including more general health-related education, such as information about self-care, medication adherence, STI prevention, and interactive toxicity beliefs. To ensure comprehension of the educational content, participants recommended utilizing a teach-back method where the person receiving the intervention would summarize the educational content and explain it to the interventionist as if the roles were reversed.

In summary, HIV patients and providers viewed the intervention as having the potential to positively impact the lives of PWH; however, several recommendations were provided regarding how best to adapt the intervention for PWH.

SWK and SAM presented the results of the coding analysis to the research team via email and scheduled one-on-one meetings as-needed to discuss and distill the results into a list of recommended changes to the adapted intervention manual. A comprehensive review of the changes made to the [PWH/FGD participant] • We moved this exercise to the second phone session to allow for more rapport-building prior to introduction of the activity Changes V. ABCs/Self-Monitoring "Antecedent" • A majority of FGD participants and providers disliked the term "antecedent" as it was considered too academic and not commonly known to this population "Well, I don't like the word antecedent, even though I know what it means but I don't think that's a common word for most people. So I just don't like it." [PWH/FGD participant] • We replaced the term "antecedent" with "Any thought, feeling, or situation that occurs before your drink."

• This modification allowed us to maintain the acronym ABCs while providing a clearer description of the self-monitoring activity Self-monitoring phone app • Both FGD participants and providers expressed interest in the use of a phone-based app as an option for collecting self-monitoring data intervention manual is outlined in Table 2 . Briefly, (1) the educational section was shortened, the 80th birthday exercise was moved to the 2nd session, the Quicksand metaphor was moved to the 3rd session, and "check-ins" to assess for understanding and sustained attention were incorporated throughout the intervention; (2) additional rapport-building was added to the beginning of the first session by asking participants to briefly share about themselves; (3) an inclusion criterion related to literacy level (8th grade level) was added, and all workbook content was reviewed to align with an 8th grade literacy level; (4) several terms (i.e., antecedent) were replaced with more colloquial language (i.e., any thought, feeling, or situation); (5) alternative metaphors and exercises were added throughout the manual in the event that a participant finds an activity emotionally overwhelming or unrelatable; (6) brief education about how mindfulnessbased skills can be applied to other areas of one's life (e.g., physical comorbidities) was added; and (7) interventionists were trained on how to tailor the intervention to participants using basic MI skills (e.g., summarizing, reflections). SWK incorporated these changes into a final adapted intervention manual, distributed it to the team, and the adaptation process moved on to Step 7. A session-by-session overview of the final manual is presented in Table 3 .

We adopted a "train-the-trainer" approach, which has been recognized as a useful method of disseminating and implementing evidence-based psychological treatments-allowing the trainer to develop supervisory skills that permit ongoing use of the intervention in new contexts [41] SWK participated in a two-day training with JB and two clinical psychologists trained in ACT. SWK read "The Happiness Trap" [64] and "ACT Made Simple" [65] prior to the inperson training, in addition to familiarizing herself with the TALK intervention manual. At the training, SWK participated in a series of role-plays such that she took turns acting as both the participant and the interventionist for each of the 5-sesions of the TALK intervention. After each roleplay, which were observed by JB and the two ACT-trained psychologists, SWK was given feedback and encouraged to share her own observations. Once SWK had successfully role-played all sessions, as both an interventionist and a participant, at a level of competency deemed satisfactory by JB and his team, she was considered trained and subsequently became the primary ACT trainer and supervisor for the ACCEPT interventionists. ACCEPT interventionists are all Masters-level PhD students in a clinical psychology program. To be trained for ACCEPT, each interventionist has to participate in a multi-day workshop modeled after SWK's training with JB. Interventionists are required to read the "The Happiness Trap" and "ACT Made Simple", in addition to the ACCEPT intervention manual. Subsequently, the interventionists are required to role-play each session of the ACCEPT intervention with SWK, once as a mock participant, and once as an interventionist. The entire training, not including the readings, takes approximately six hours. Once trained, ACCEPT interventionists are required to participate in one hour per week of group supervision, led by SWK and SAM, for the duration of their tenure on the ACCEPT trial.

In group supervision, audio of the intervention sessions is reviewed and discussed, as well as any practical issues in the delivery of the ACCEPT manual.

The final step of the adaptation process was to develop detailed standardized operating procedures (SOPs) for a pilot RCT designed to determine the feasibly and acceptability of the ACCEPT intervention ahead of a full-scale RCT. SOPs covered all relevant aspects of the execution of the RCT including (but not limited to): recruitment, screening, consent, scheduling, collection of self-report and biospecimen data, interventionist training and supervision, retention, and adverse events. SOPs were developed through an iterative process that involved multiple weekly team meetings, with input from RAs, project coordinators, and faculty Co-Investigators. Co-PIs SWK and SAM provided detailed feedback on the initial drafts of each SOP until a final laboratory manual was developed to train all study staff. The final manual is 74 pages, and includes 34 distinct SOPs, and 32 appendices. All study staff are required to read the entire lab manual as part of training, and to collect data from 1-2 mock research participants prior to the official onset of data collection. The manual is reviewed annually by the Co-PIs and the study staff to ensure accuracy and fidelity to procedures. Interim concerns are discussed during weekly lab meetings with the research team, with changes made on an as-needed basis. The lab manual will serve as the basis for the implementation of the pilot and eventual full-scale RCT.

We successfully adapted a telephone-delivered ACT-based treatment for PWH who are hazardous drinkers. Using the ADAPT-ITT model, we implemented the adaptation process in several structured phases that included multidisciplinary team meetings, feedback from key stakeholders, and iterative changes responsive to both. As a result, we have a standard treatment manual that will ultimately be used in a fullscale RCT designed to test the efficacy of the adapted ACT intervention. We also formalized procedures for training There have been several efforts to increase transparency and rigor in reporting on the development and implementation of psychological and behavioral RCTs [66, 67] . Consistent with this movement, models such as ORBIT Model for Behavioral Treatments [53] and the Stage Model of Behavioral Therapies Research [68] [69] [70] have been developed to standardize and operationalize the behavioral treatment development process, from early phase developmental studies (Phases I-II) to efficacy (Phase III) and effectiveness (Phase IV) RCTs. These models suggest that early phase studies include: the specification of a hypothesized pathway by which an intervention could solve a clinical problem, the adaptation or development of an intervention and an associated training manual, the determination of mode and frequency of intervention delivery, development of a training and supervision program for study clinicians, development and piloting of standardized operating procedures for the efficacy trial, and eventual demonstration of feasibility and acceptability. We used the ADAPT-ITT model to further standardize and guide the intervention adaptation process and development of the adapted intervention manual. Implementing the suggestions of these models, and reporting on this process in peer-reviewed publications, is consistent with the movement to increase reproducibility in NIH-funded clinical research [71] , and adds to the growing literature on the development of alcohol interventions for PWH.

The ACCEPT intervention, and the process by which it was developed, has several strengths. First, our decision to adapt an existing intervention, rather than develop one from the ground up, allowed us to leverage Bricker et al.'s innovative work on a novel treatment with high potential to reduce alcohol use among PWH. Doing so accelerated the process by which we could move through the phases described in the ORBIT and Stage Models of Behavioral Therapies Research. Second, the telephone-delivered format of the TALK intervention provided evidence that the intervention could be successfully delivered via telephone. The ACCEPT intervention could therefore be developed as a telehealth intervention, increasing the likelihood that, if efficacious, it can be feasibly integrated into HIV care settings. The COVID-19 pandemic has significantly increased the use of telemedicine in health care, expanding the provision of psychological services to those who would otherwise be unable to access them [72] . Telehealth-delivered mental and behavioral health care may be a particularly novel and useful tool for PWH given that HIV clinics often serve large geographic areas with highly diverse patient populations who have a wide range of psychosocial barriers to accessing care [73, 74] . Third, while the ACCEPT intervention was designed to target alcohol use, the skills and mechanisms by which it is hypothesized to do so underlie a wide range of psychological and behavioral health concerns. ACCEPT thus has the potential to be flexibly applied to patient populations, such as PWH, who present with diverse psychosocial and mental health needs.

We also acknowledge some limitations. First, the patients and providers included in Step 5 were from a single HIV clinic in a medium-sized city in Central New York. While valuable, the feedback provided about the ACCEPT intervention is restricted to a small sample from a relatively small HIV clinic in the Northeastern United States, that was composed predominately of Black, cis-gendered men. While we do not expect issues with generalizability in the skills, metaphors, and activities included in the intervention, it is possible that regional variability in contextual factors such as HIV-related stigma and access to HIV-related services could affect participant's willingness and/or ability to engage with intervention content. It is also possible that transgender individuals living with HIV, and cis-gender women living with HIV, may have reactions to intervention content that were not represented in our formative work. Regarding this limitation, the feasibility/acceptability RCT recruited participants from the entire U.S., and as part of this trial we are soliciting additional feedback about intervention content. We will thus be able to review and integrate feedback from a larger and more diverse group of PWH prior to implementation of the full-scale efficacy trial. Second, given the time constraints associated with the IDIs and FGDs, we were only able to role-play a proportion of the experiential exercises and metaphors from the ACCEPT manual. We were thus unable to solicit feedback on the entire manual. Future studies using the ADAPT-ITT model could hold a series of FGDs, each of which is designed to solicit feedback on a different section of the treatment manual, thereby ensuring that feedback is received on the entire intervention. We will also be able to partially address this limitation via the pilot RCT in which intervention participants who have received all six sessions will be asked to comment on their overall experience of the intervention.

ACT is a novel and promising transdiagnostic treatment for alcohol use. Using the ADAPT-ITT model, an existing brief, telephone-delivered, ACT intervention developed for smoking cessation was successfully adapted for PWH who drink at hazardous levels. An ongoing pilot RCT will formally determine feasibility and acceptability of the ACCEPT intervention, and a planned Phase III RCT will determine the relative efficacy of ACCEPT compared to an existing brief alcohol intervention already shown to be efficacious for PWH [75] . The procedures described here are an example of how to apply the models that have been developed to increase transparency, rigor, and reproducibility in behavioral RCT research.
