The purpose of this study was to evaluate the feasibility, acceptability and preliminary outcomes of a mindfulness-based group intervention delivered to parents virtually. It was feasible to deliver this manualized intervention. Twenty-one of 39 parents completed the intervention and completers reported high satisfaction ratings. Parents reported reduced levels of distress, maintained at 3-month follow-up, and increased mindfulness. Changes reported following intervention were similar to changes reported in a prior study of parents competing an in person mindfulness group. with autism and other developmental disabilities relative to other parents (Lunsky et al. 2014) . However, there are few interventions targeted toward parent mental health. Mindfulness, paying attention in a particular way: on purpose, in the present moment, and non-judgmentally (Kabat-Zinn 2003, p. 145) , is associated with positive mental and physical health in diverse populations. Empirically supported mindfulness based interventions, such as mindfulness based stress reduction or mindfulness based cognitive therapy, teach both formal (e.g., body scan, breath meditation, walking meditation) and informal mindfulness practices (e.g., noticing sensations while brushing your teeth) and typically include learning a new practice or mindfulness skill in session followed by discussion (inquiry) about the experience and independent rehearsal of the activity as homework. Typically these skills are practiced by listening to an audio-recorded guided meditation exercise similar to the one taught in session. Recent systematic reviews (Cachia et al. 2016; Donnchadha 2018; Hourston and Atchley 2017) and a meta-analysis (Hartley et al. 2019) reported that mindfulness-based interventions may be effective for parents of autistic people in reducing stress, and improving overall well-being. Existing research on mindfulness-based interventions has tended to focus on parents of younger children as opposed to older autistic adolescents and adults. Parents of older individuals may benefit from mindfulness because of the chronic stress they have been exposed to over time, their own emerging health issues that come with age, combined with the many gaps in services that autistic adults experience once school ends (Lunsky et al. 2015) . In the only mindfulnessbased group Randomized Controlled Trial (RCT) targeting parents of older adolescents and adults with developmental disabilities (50% with autism), parents reported reduced depression and stress when compared to an active psychoeducation control, and these reductions were maintained at 3-month follow-up (Lunsky et al. 2017) . Unfortunately, not all families can commit to multi-week, in-person interventions because of caregiving demands and systemic barriers (Stjernsward and Hansson 2019). Further, specialized mindfulness-based skill groups for family caregivers are typically only available in larger communities, creating barriers for those living in rural or remote areas. Even if families can access in-person mindfulness training targeted toward the general population, a general mindfulness program may not be as effective as a program that is oriented to fit parents' unique needs. Such tailoring may include practicing with other parents in a similar situation, and with modified exercises and expectations to accommodate their intensive caregiving responsibilities (Lunsky et al. 2015) . There has been increased attention in the mindfulness literature to delivering interventions virtually (Mikolasek et al. 2018) , and a general trend toward promoting technology facilitated interventions and telemedicine as one way to improve access to mental health care, and reduce health care costs (Gentry et al. 2019) . Mindfulness based instruction can be offered virtually through both synchronous and asynchronous means. Synchronous delivery means that everyone taking part is doing so at the same time, similar to an intervention being held in person, whereby people can see and hear each other's responses in real time. An asynchronous intervention can be held individually or in a group, but group members need not be present at the same time. It can involve everyone viewing a recording or completing an exercise within a given time frame and sharing reactions to it with other group members and the facilitator. Asynchronous approaches offer the advantage of flexibility to set the time of participation and the pace of learning. There are several Apps freely available (Mani et al. 2015) and a number of studies showing that asynchronous instruction (whether individual or group based) can be beneficial to a number of user groups (Mikolasek et al. 2018) , including autistic adults (Gaigg et al. 2020 ) and parents of people with developmental disabilities (Flynn et al. 2020) . However, the asynchronous format, whether individual or group based, does not allow for real time feedback from the instructor, nor does it allow the same group of participants to interact as a group with one another at the same time (Fish et al. 2016) . This is particularly relevant to mindfulness training, as the inquiry process, fundamental to mindfulness instruction, is best done within a group, with immediate feedback (Crane et al. 2015) . In addition, in group-based mindfulness interventions participants have the advantage of learning from others' experiences. There is also a secondary benefit of reducing one's sense of isolation through meeting others in similar situations. This is of particular importance to isolated family caregivers. Synchronous virtual interventions may offer the same advantages as in person interventions, with the exception of being in the same physical space. A recent systematic review of group based virtual interventions in general (Gentry et al. 2019 ) concluded that such groups are feasible and produce outcomes similar to in-vivo treatments with high participant satisfaction. Only one of the 40 studies reviewed, however, focused on a mindfulness or acceptance-based program offered to family caregivers, in this case parents of children with a life threatening illness (Rayner et al. 2016) . Four other programs (of the 40 reviewed) focused on caregivers, and offered either psychoeducation or peer support. Although researchers have demonstrated the effectiveness of telemedicine more broadly within the autism community (Knutsen et al. 2016) with high rates of parent satisfaction, the focus has typically been on the autistic person or on teaching parents skills in relation to engaging with their child (e.g., Pennefather et al. 2018) . To our knowledge, researchers have yet to explore the feasibility of virtual synchronous group-based mindfulness interventions specifically with parents of autistic youth and adults. To address barriers to in-person mindfulness-based approaches, we modified the group based mindfulness intervention described in Lunsky et al. 2017 for online synchronous delivery (described in the 'Methods' section). Delivering the intervention virtually enabled therapists to bring together older parents from across the country using a freely accessible and virtual meeting space, to provide live therapeutic experiences in participants' own homes. The current study was designed to answer four questions: 1. Feasibility-Did the technology work (technology feasibility), could we recruit parents successfully (recruitment feasibility), and what proportion of people who completed baseline measures completed follow-up assessments (evaluation feasibility)? 2. Adherence-What proportion of people who enrolled in the groups attended sessions, and how many sessions did people attend? How many attendees completed the intervention? 3. Acceptability-Generally, how did parents experience the synchronous online intervention and how satisfied were they with its virtual format? 4. Utility: Was there some initial evidence that the outcome measures used in a prior in person delivery of this intervention were sensitive to change when delivered virtually? 5. Additionally, we explored an initial comparison of the outcomes from the synchronous virtual model with those of similar parents who participated in an earlier study of the same group-based mindfulness intervention delivered in person. Participants were 39 parents, primarily mothers, of adolescent and adult-aged autistic sons and daughters from seven provinces in Canada. To participate, they required access to a computer, tablet or smartphone. Demographic information for this sample is presented in Table 1 . A 14-item modified version of the 21-item Depression, Anxiety & Stress Scale (DASS-21; Henry and Crawford 2005) , which included the seven depression and seven stress items only, was used to measure overall psychological distress at each time point. Items were rated using a 4-point Likert scale ranging from 0 ("Did not apply to me at all") to 3 ("Applied to me very much, or most of the time") and were summed to yield a single total score between 0 and 42 with higher scores indicating greater levels of distress. The DASS has been used as a measure of parent psychological distress in both intervention and non-intervention studies that included parents of autistic individuals (Conner and White 2014; Lunsky et al. 2015; Rayan and Ahmad 2018) . In a previous study (Lunsky et al. 2017 ), a 14-item psychological distress score demonstrated excellent internal consistency (Cronbach's α = 0.94). Internal consistency of the 14-item DASS was also excellent for the current sample (Cronbach's α = 0.93). The 39-item Five-Facet Mindfulness Questionnaire (FFMQ; Baer et al. 2006 ) was used to assess five components of mindfulness: observing one's experiences, describing one's experiences, acting with awareness, accepting inner experiences in a nonjudgmental way, and accepting inner experiences without reacting. Parents were asked to rate how generally true each item was for them using a five-point scale ranging from 1 ("Never or very rarely true") to 5 ("Very often or always true") with higher total scores suggesting greater mindfulness (total score range from 39 to 195). Results from the current study indicate the FFMQ total score has excellent internal consistency (Cronbach α = .91). The Bangor Mindfulness Parenting Scale (BMPS; Jones et al. 2014 ) is a 15-item measure that was developed based on the FFMQ. The tool was designed to measure each of the five facets of mindfulness described in the FFMQ, but specifically within the context of parenting (e.g., "When I have upsetting thoughts about my child, I am able to just notice them and let them go."). Parents were asked to indicate how true each item was for them on a four-point scale, ranging from 0 ("Not at all true) to 3 ("Always true"). A total sum of the 15 items was calculated to provide a general indication of mindful parenting with higher scores indicating more mindful parenting (total score range from 0 to 45). Results from previous mindfulness intervention studies using the BMPS illustrate internal consistency ranging from acceptable (Cronbach α = .78) to good (α = 0.83; Jones et al. 2014; Lunsky et al. 2017) . Internal consistency of the BMPS for the current sample was good (Cronbach's α = .85). The Self-Compassion Scale-Short Form (SCS-SF; Raes et al. 2011 ) is a 12-item measure that assesses the ability to demonstrate care and kindness toward oneself, and acceptance of one's own imperfections. Self-compassion is often a focus of mindfulness-based interventions because of the interrelatedness with state mindfulness (Neff 2003) . Responses were given using a five-point Likert scale that ranged from 1 ("Almost never") to 5 ("Almost always"), yielding a total score between 12 and 60, with higher scores indicating greater self-compassion. The SCS-SF had good internal consistency for the current sample (Cronbach α = .89). Carer burden was assessed using the 9-item subscale of the Revised Caregiving Appraisal Scales (Lawton et al. 2000) . Items measure caregiver perceptions of the negative impact caregiving has on health, well-being, social life and personal relationships. Responses are scored using a 5-point Likert scale, yielding a total score between 9 and 45 with lower scores reflecting greater perceived burden. The scale had excellent internal consistency in the present study (Cronbach's α = .90). The Positive Gain Scale (PGS; Jess et al. 2020 ) is a 7-item measure of how having a child with a disability has positively contributed to the family's experiences. For the purpose of this study, the measure was adapted to be relevant to having an autistic child by editing the instructions and items to refer to the offspring with autism. Responses were provided on a 5-point scale, ranging from 1 ("Strongly disagree") to 5 ("Strongly agree") with lower scores indicating more positive contributions (total score range from 7 to 35). The scale demonstrated acceptable internal consistency (Cronbach's α = .77). In addition, parents completed a 17-item satisfaction measure. Responses to 9 questions about the intervention were rated on a 5-point Likert scale from 1 strongly disagree to 5 strongly agree, based on the satisfaction questionnaire utilized in Lunsky et al. 2017 . Eight additional satisfaction items focused on technological aspects of the intervention (e.g., ease of software, comfort with technology, connection to other parents) and were rated on a 7-point Likert scale. Parents also provided responses to open-ended questions asking about what they liked best and least about the group, what the biggest challenges they had to attending group meetings, what would make participation easier, and how they would change the group for future participants. Participants were recruited through local autism service e-newsletters, website postings, and advertisements shared through social media (e.g., Twitter, Facebook). Interested parents completed a brief screening assessment to determine if they met eligibility criteria (i.e., had an autistic son or daughter 16-years of age or older, lived in Canada, were available on the dates of the group). Informed consent was then obtained electronically from eligible parents. Parents were then sent a survey link to complete the baseline measures. Prior to the first intervention session, individual meetings were scheduled to provide parents with a walkthrough of the video-conferencing platform (Zoom) to familiarize them with the software and minimize the potential for technology-related impediments. Parents could participate from home or another setting, so long as it was private, using a tablet, computer or smart phone, with a web camera. Four groups were run consecutively between Spring of 2017 and Spring of 2018. All parents who registered for the study and completed baseline measures were sent the measures again a week after the 6-week intervention ended, and at 12 weeks follow-up, unless they formally withdrew from the study. Parents received a small honorarium of 15 dollars after completing the follow-up measures. The group-based intervention was an adaptation of mindfulness based cognitive therapy (MBCT) facilitated by coleaders who had prior experience facilitating the in person version of this manualized program, and had training in the delivery of mindfulness-based interventions. Parents received a workbook which outlined the six sessions, summarized the mindfulness activities taught, listed the weekly homework and included links to audio recordings of the formal meditation practices. This workbook was adapted from the MBCT program, but with a family caregiver and developmental disability focus. This 6-week course taught participants mindfulness skills (breathing meditation, body scan, mindful yoga, walking meditation, and loving-kindness), alongside other parents. Each session began with a homework review and brief meditation (a review from the prior week), followed by instruction in a new meditation technique, group inquiry where the leaders facilitated discussion about how people experienced the exercise, an explanation of homework and a closing reading, typically a poem. Homework was outlined in the parent workbooks and always included practicing the new formal practice taught that week, as well as an informal mindfulness activity, and links to meditation recordings were made available to all participants (for more detail see Lunsky et al. 2017 ). The in-person intervention differed from more traditional MBCT in that the audio practice recordings were briefer (10-15 min), as were exercises within the class, knowing that families can have difficulty finding 30-45 min to complete practices while caregiving. There were fewer sessions in total (6 versus 8) and there was no full day silent retreat. When formal practices were taught to the group, there was always time for discussion on how to integrate such practices into daily life as a busy caregiver. Practices were adapted for older individuals who may have had sensory or mobility issues. The 3-min breathing space was emphasised because of its practicality to parents, and a loving-kindness meditation was included to support families to develop compassion for themselves and their children. Each session included a 20-min tea break for families to connect with one another, recognizing the value of that parent to parent time. Modifications to the in-person intervention to make it appropriate for virtual delivery included shortening each session from 2 h with a 20 min break to 90 min. This was done because parents could not informally interact with other parents as they could in person, and because, due to the online nature of the intervention, parents could take a brief break if needed during the 90 min without disrupting others. The decision to shorten each session in this manner was made by the clinicians, researchers and parent advisors together as a way of making the intervention most accessible and recognizing the limitations of virtual technology. The virtual technology allowed parents to communicate with each other verbally as a whole group, but also through typed comments in the chat box. Anonymous group polling was another way of engaging with participants. For example, parents could vote on their experience completing homework, or their reaction to a formal practice. This allowed parents to see in real time how others experienced an activity, without each parent having to raise their hand in front of their peers. Another modification was that each session had a technology facilitator who addressed technical issues, so that the mindfulness training facilitators could focus on content. The same technology facilitator oriented parents to the software before the first session took place, and was also available for technical support in between sessions. Rather than distribute workbooks to participants at the first session, they were sent the workbook as a PDF to print, and recordings were made available via internet links. Weekly meditations were video recorded and then posted online on a closed Facebook group page, so that people who missed the session could practice what they had missed. Other helpful resources were occasionally shared between parents on that site. To assist with group facilitation and to provide an enriched, family informed evaluation, the intervention included two parent advisors in addition to the pair of clinician facilitators. These parents were present for each session and participated in exercises with other participants. They sometimes reflected on their experience, particularly when the group was quiet, and offered a reading or poem at the end of each session. They met with the group facilitators before and after each session to plan and debrief. The two parents in these roles had participated in a prior parent mindfulness study with the research team, and had experience providing peer support and working with families. Linear mixed-effect modelling was employed as the primary tool to examine the intervention effect within the virtual intervention. The outcome measures of DASS 14, FFMQ, BMPS, Burden, Self-compassion scale, and Positive Gain scale at all three time points (baseline, post-intervention, and 3 months) were treated as the dependent variables respectively. In addition to having the time indicator as the primary predictor of three levels, we also accounted for random effects at individual level for the repeated measures and at group level since the intervention was conducted in a group setting. For the between-intervention analysis, observations from the virtual and in-person mindfulness interventions were pooled and analyzed using linear mixed-effects models. The changes from baseline and post-intervention of the six outcome measures were entered into the model as the dependent variables respectively. Only group level random effects were included in this analysis. We report both unadjusted and those adjusted p-values in Table 4 . The latter were obtained by controlling for the baseline measure of the same outcome to account for baseline differences between the virtual and in-person interventions. The within virtual intervention analysis only contained those who provided complete data at all three time points, and the between-intervention analysis contained those who provided complete data at baseline and post-intervention. Feasibility was assessed with regard to ability to recruit (recruitment feasibility), the reliability of technology (technology feasibility) and the proportion of people who completed measures at each time point. (evaluation feasibility) We were able to recruit participants through social media in the reported timeframe (43 parents consented to the study). Of these parents, 39 completed the baseline measures. Fewer participants completed the post (21) and follow-up measures (19). Most of the people who did not complete these measures had stopped attending any intervention sessions. Only one individual who completed fewer than 3 sessions completed the post questionnaires. We were able to cover all of the manualized content in the six sessions, including the walking meditation. For that activity, we invited participants to step away from their computers and listen to the voice of the facilitator. The technology worked for each session. When one participant had difficulty with technology, the technical support person was usually able to assist using the chat function without disrupting the flow of the session for other participants. As demonstrated in the participant flow diagram (Fig. 1) , Of the 39 parents who consented to the study and completed the baseline survey, 34 participated in at least one session, and 21 were considered completers (attended at least four of the six sessions). A total of six parents dropped out of the intervention after attending a single session. Of the 11 people who only attended one or two sessions, reasons for not continuing included that the timing was difficult, that they had pressing issues to address with their son or daughter, or that they were not interested in learning mindfulness. There were no significant differences between participants who completed the program and those who completed three or fewer sessions in terms of demographics or baseline scores on outcome variables with the exception that noncompleters were more likely to have female children, χ 2 (2, N = 34) = 6.48, p = .039. Satisfaction ratings of participants, completed at post-treatment, were consistently high in terms of utility of what was learned and applicability of information (Table 2) . Total satisfaction scores for intervention-specific questions were high (M = 42.71, SD = 2.80) and similar to total satisfaction scores reported in the in-person study (M = 40.21 SD = 9.02). Parents rated items highly about the virtual mode of engagement, with the highest scores given for ease of use of technology, and convenience of online engagement. Scores were slightly lower for comfort with web-based technology and technological issues. Almost all parents rated that the felt connected to other parents. The majority of parents (14/18) endorsed that inclusion of the closed Facebook group for parents was useful. Parent responses to open-ended questions about what they liked best about the program and challenges they experienced fell into three themes: the value of connecting with others in similar situations, the benefits of and challenges with technology, and the utility of mindfulness-based skills. Many parents highlighted that connections with other parents were important. For example, parents noted: "I like the fact that I was with a group of women that seemed to live similar challenging lives involving kids/persons that weren't mainstream and required a different approach." and that: "I was very grateful to have the opportunity to learn these techniques in the context of other parents who face similar challenges.", feeling that there was a community to engage with. Participants reported that the technology was helpful in several ways, allowing for both text and verbal communication options. Parents commented that "Communicating was easier than I thought it would be-especially with the texting option," as well as being able to participate from different locations (including home, work, the car, or while traveling). Being able to access recordings of the mindfulness practices when a session was missed was also listed as an advantage of the technology: "The only challenge I encountered was with pre-existing commitments. I really appreciated having the recordings on Facebook to assist for those days." However, there were some frustrations with the technology experienced by some participants, especially at the start. One parent described a "technology difficulty with my own equipment, my camera was broken, so I couldn't be seen." Another described that "I really disliked seeing my appearance on the screen during sessions." Several aspects of the intervention were described as particularly helpful including the learning of practical skills: "practical meaningful skills to apply for the rest of my life, that give me hope that I might be able to cope, and perhaps even cope well." The unconditional accepting nature of group members and facilitators was also highlighted: "Moderators and other participants seemed to be very accepting. Although I often have trouble expressing myself, I didn't have any fear in sharing with the group." Parents offered some helpful suggestions to improve the intervention, several of which leveraged technology. This included the suggestion of automatic reminders in their calendar for attendance and practice, the posting of recordings of sessions to review if they were missed, and more instruction and support to participate in an online forum for those less comfortable with using Facebook. During the session itself, one parent thought it would be helpful if the agenda could appear on the screen to guide the session. As demonstrated in Table 3 , parents reported reductions in stress and depression , as well as improvements in mindfulness (FFMQ), which were maintained at 3-month follow-up. They also reported improved scores in mindful parenting and self compassion and positive gain, and increased scores on the burden scale which suggests a reduction in overall burden between Time 1 and Time 2. Improvements were maintained between Time 2 and 3 for all measures except perceived burden. To assess whether changes reported between Times 1 and 2 in the virtual intervention differed from scores reported by parents who participated in the equivalent in-person mindfulness group intervention (Lunsky et al. 2017) , an linear mixed-effects models were employed, with change between Time 1 and Time 2 scores as the dependent variable, type of intervention as the between-subject independent variable. The Time 1 ratings were added as a covariate in an adjusted model to account for baseline differences. Four cohorts of both the in person and virtual interventions were held and clustering by the cohort parents participated in was accounted for. Results suggest (see Table 4 ) that the two interventions did not differ in their outcomes at Time 2. This study explored whether a 6-week mindfulness-based group intervention for parents of older autistic adolescents and adults held virtually was feasible, acceptable, and led to improved clinical outcomes. We were able to recruit enough people for the intervention, the technology was reliable and we were able to cover the same content as we addressed in a prior in person intervention. Overall satisfaction rates were high for those people who remained in the program, but there were some challenges with technology as well as barriers to participating for some caregivers because of competing responsibilities. Parents who completed the intervention reported improved mindfulness and reduced stress and depressed mood, and these reported changes were maintained at 3 month follow-up. The patterns observed in the current project were similar to parental reports in a prior in-person study. This intervention was feasible in terms of recruitment and the technological aspects. Our recruitment strategy using social media and asking community autism agencies to circulate information led to sufficient numbers of people, but did not capture people equally across geographic regions. To best promote participation in a study like this, it would be important to allow for at least 2-3 months of time to engage with agencies and family groups so they could share information. It would be worthwhile to develop a research poster that adequately captures the details of the intervention, as well as the research component. About 40% of people who expressed an interest in the project either had younger children or could not attend on the day the intervention was being held. Although almost all of the parents who met criteria for the study and consented completed the baseline measures, the majority of non-completers opted not to complete post and follow-up study measures. It would be important in a larger trial to emphasize the importance of completing all measures regardless if they completed the intervention, and to provide incentives to parents who completed all of the measures, regardless of whether they opted to continue in the study or not. With regard to adherence, just over half of the people who enrolled in the study and filled out baseline measures completed the intervention and one third attended 1-3 sessions. It would be important in future work to more closely examine why certain individuals do not stay in virtual groups and whether greater orientation to the purpose of the group prior, additional 1:1 technical coaching after the first session, or web-based resources would help with participation. Research on online treatments with other populations have reported that weekly reminders, individual coaching, and some in-person contact have all been helpful to improve participation. It would also be interesting to explore in further work whether parents who attend in-person intervention feel more committed to it, or have a greater sense of group cohesion than in a virtual setting (Gentry et al. 2019) , making their continuation more likely. Although clinically we defined completion as attending 4 of the 6 sessions, future larger-scale research could also examine dosage effects and whether any benefits are apparent from engaging in fewer sessions. In addition to being accessible to people who live remotely, certain aspects of online synchronous groups may be more appealing to family caregivers than in-person groups. These include the ability to mute oneself or take a small break to tend to a childcare issue, the time and cost saved not having to travel to a group or arrange childcare, and the ability to view recordings of the exercises that occurred online after session. Given the challenges parents experience and the shortage of time they have to tend to their own needs, the flexibility that comes with virtualbased groups can be important. As parents become more comfortable with technology, including older parents, the appeal of such modes of participating may become greater. Because of the COVID Pandemic, it is expected that many more families will be more accustomed to both virtual social connections and virtual health and social care. Similar to in person caregiver mindfulness studies, reductions in distress were reported by parents in the current study. One intriguing finding was the reported shift in mindfulness scores, with parents reporting higher scores on three mindfulness measures, which were maintained at follow-up. Prior in-person mindfulness studies have been inconsistent in this regard. For example, while some inperson studies have reported improvements in mindfulness scores (Bazzano et al. 2015; Benn et al. 2012; Ferraioli and Harris 2013), Lunsky et al. 2015 Lunsky et al. , 2017 did not find changes in mindfulness, following a similar 6-week intervention, even though distress scores decreased. It is possible that removing some of the in-person aspects of the intervention heightened the focus on mindfulness skills. Though not commented on by participants, the ability to practice mindfulness in the same setting where home practices take place may help with change and maintenance over time (Cooper et al. 2019 ). Alternatively, it is possible that parents already familiar with using online resources to participate in the group are more able to use online homework practices than parents who participate in person, or that the parents willing to participate in this type of intervention were more primed toward developing mindfulness skills. More research capturing the amount of practice and engagement with online materials would be important. One important aspect of this study was the role of the parent advisor, which was not part of the earlier in-person study (Lunsky et al. 2017) . Each of the three cohorts included two parents of autistic adults, who had participated in a prior mindfulness intervention. These parents, both of whom had prior experience supporting other parents, met with the clinicians leading the intervention each week, prior to and following the session, and also played a role in the sessions themselves, sometimes reflecting upon their own experiences, and closing each session with a relevant reading. In an era where patient-oriented research is increasingly recognized and valued (e.g., SPOR in Canada, PCORI in the US and INVOLVE in the UK) (Aubin et al. 2019) , it is important that we further explore how parent advisors can help to improve delivery of services, and the impact of the parent role on therapists and group participants. Following delivery of these virtual groups, the parent advisors and lead clinicians have further adapted the parent workbook, as well as the session structure, in an effort to improve delivery, and are currently involved in the delivery and evaluation of this next iteration. To more fully study whether parents in an advisory role contribute to the gains reported here, similar groups without such advisors would need to be conducted as a comparison. This study has several limitations which should be taken into account. Very little information was obtained from families who stopped attending sessions besides general reasons for dropping out. Although some changes were reported and the main mindfulness instructor was the same, the in-person group was not matched to the virtual group, individuals were not randomly assigned, and neither therapist nor participants could be blinded to their condition. A further controlled study with a larger sample is required. Greater emphasis on collecting trial data, regardless of adherence would be important and financial incentives would be helpful in this regard. These preliminary findings are based on a small group of keen parents eager to participate and may not generalize to other families, especially families less comfortable with technology or with limited means to access the required technology. It is worth noting that internet use across Canada is increasing with 91% of people older than 15 reporting using it, including 71% of seniors (Statistics Canada 2019). Few fathers participated in these groups, so it is difficult to comment on how effective it could be for them, or whether something tailored more specifically to men would be helpful. No information on treatment adherence was collected beyond attendance, no homework tracking, listening or viewing of mindfulness practices was completed, and no fidelity measures were used. Because each of the three cohorts had the same facilitators and parent advisors, using the same manual and parent workbook, we expect that sessions were delivered in a similar manner but it is possible that over time the team of two clinicians and two parents improved. Finally, it would be important to evaluate the role of parent advisor more formally. Parent-focused interventions to promote their mental health are important when someone in the family is autistic. How to deliver such interventions should be informed by the families who would benefit from such efforts. Given the challenges with being able to make family-based interventions accessible to all families, further exploration of the practical, clinical and economic benefits of holding a synchronous group based mindfulness intervention virtually would be beneficial. Indeed, knowing whether there is any further benefit for parents to participate in mindfulness training virtually together as opposed to asynchronously alone is important to explore.
