The COVID-19 pandemic has resulted in elevated mental health problems for pregnant women. Effective coping strategies likely reduce the impact of COVID-19 on mental health. This study aimed to (1) understand how COVID-19 stressors are related to different coping strategies and (2) identify whether coping strategies act as mechanisms accounting for the associations between COVID-19 stressful experiences and mental health problems in pregnancy. Participants were 304 pregnant women from Ontario, Canada. Depression, anxiety, insomnia, and perceived stress were assessed using validated measures. COVID-related stressors (i.e., financial difficulties, social isolation), subjective negative impact of COVID-19, and coping strategies used in response to COVID-19 were assessed by questionnaires. Results indicated that the subjective negative impact of COVID-19 was associated with more dysfunctional coping and less emotion-focused coping, whereas specific COVID-19 stressors, namely financial difficulties and social isolation, were associated with more dysfunctional coping and problem-focused coping. Dysfunctional coping was linked to elevated mental health problems and emotion-focused coping was linked to less mental health problems. Dysfunctional coping and emotion-focused coping partially mediated the effects of specific COVID-19 stressors on mental health outcomes. Findings indicate that coping is one pathway through which the COVID-19 pandemic impacts mental health in pregnancy. Supports and interventions for pregnant women during the pandemic should focus on bolstering coping skills, in order to minimize the mental health consequences of COVID-19.

The COVID-19 pandemic is causing elevated distress across populations. Systematic reviews and meta-analyses, integrating research from across the globe, indicate that a substantial portion of the general population is experiencing high rates of depression (25-34%) and anxiety (25-32%) during this pandemic (Bueno-Notivol et al. 2021; Ren et al. 2020; Salari et al. 2020) . Similarly, pregnant and perinatal women are experiencing comparably elevated rates of depression (25-31%), anxiety (34-42%), and psychological distress (70%) (Fan et al. 2020; Sun et al. 2020; Yan et al. 2020) . Pre-COVID research shows that pregnancy is a period of vulnerability, characterized by higher prevalence of anxiety and depression compared to the general population (meta-analyses: Dennis et al. 2017; McCance-Katz 2019; Woody et al. 2017) . While mental health difficulties appear similarly elevated in pregnant and nonpregnant samples during the COVID-19 pandemic, prenatal mental health problems increase risk for adverse birth effects and developmental outcomes (meta-analyses: Grigoriadis et al. 2018; Madigan et al. 2018) . Importantly, the degree to which COVID-19 impacts mental health is variable. Effective coping strategies likely act as a protective factor that mitigates the impact of COVID-19 on mental health. Indeed, engaging in self-care, including physical activity and healthy eating, is Women's mental health during the Covid-19 pandemic Edited by: Anita Riecher-Rössler linked to better wellbeing during the pandemic (Davenport et al. 2020; Deng et al. 2020; Farewell et al. 2020; Lebel et al. 2020) . However, it remains unclear how specific coping strategies impact mental health outcomes in pregnant women during Coping is a primary component of an individual's response to stressful events (Folkman and Lazarus 1980) . Research has distinguished between three major types of coping: (1) problem-focused coping, which involves actions aimed at addressing the problem (e.g., planning, seeking instrumental support), (2) emotion-focused coping, which aims to manage negative emotions (e.g., seeking emotional support, cognitive restructuring), and (3) dysfunctional coping, which involves maladaptive strategies that are not helpful in dealing with the stressor (e.g., denial, behavioral disengagement) (Carver 1997; Folkman and Moskowitz 2004) . Indeed, dysfunctional coping has been associated with adverse mental health outcomes in pregnant women across different circumstances Guardino and Dunkel Schetter 2014; Gutiérrez-Zotes et al. 2015; Lau et al. 2016) . In contrast, the effects of problem-focused and emotion-focused coping are mixed, though these strategies tend to be associated with more positive outcomes in pregnant women (Guardino and Dunkel Schetter 2014 for review) . Furthermore, different forms of coping have been shown to act as mechanisms/mediators between stressful experiences and mental health outcomes in pregnancy (Choi et al. 2015; Greene et al. 2021; Giurgescu et al. 2006; Zhang et al. 2020) .

Several studies have shown that effective coping strategies are associated with better psychological wellbeing during the COVID-19 pandemic, including reduced anxiety and depression (e.g., Brehl et al. 2021; Groarke et al. 2020; Jiang et al. 2020; Jungmann and Witthöft 2020; Fullana et al. 2020 ). In addition, two studies have specifically examined the role of coping as a mediator between stress and mental health outcomes during the COVID-19 pandemic. In a sample of college students, Ye et al. (2020) showed that COVID-19 stress was related to more maladaptive coping and less adaptive coping strategies, and that adaptive coping mediated the link between COVID-19 stress and acute stress disorder. In contrast, in a sample of the general public, maladaptive coping mediated the effect of intolerance of uncertainty on mental health outcomes (Rettie and Daniels 2020) . Additional research is needed to determine which forms of coping act as mediators linking COVID-19 stress and mental health in pregnant women.

Identifying the pathways through which COVID-19 is associated with mental health in pregnancy is necessary to inform public health initiatives aimed at ameliorating the mental health outcomes of this pandemic. The present study examined how the subjective impact of COVID-19 and COVID-19 stressors (financial, social isolation) were associated with coping and mental health outcomes in pregnant women. The objectives of this study were to (1) determine how COVID-19 stressful experiences are associated with different forms of coping; (2) examine how coping strategies are related to mental health, and (3) identify whether coping strategies act as mediators of the associations between COVID-19 experiences and mental health problems in pregnancy.

Participants were 304 pregnant women between 19 and 44 years old (M = 32.09, SD = 4.27 years) and 4 to 36 weeks gestation (M = 21.44 weeks, SD = 8.93 weeks) (see Table 1 for sample characteristics). Participants completed online surveys between June and July 2020. This was a convenience sample; recruitment was primarily conducted through social media advertisements (eliciting participant in a study assessing how COVID-19 impacts wellbeing during pregnancy). Inclusion criteria were that individuals (1) live in Ontario, Canada, (2) read and write in English, (3) be 18 years of age or older, and (4) be ≤ 36 weeks gestation. This study was approved by the Hamilton Integrated Research Ethics Board under Project #11,034.

The 10-item Centre for Epidemiologic Studies Depression Scale (CES-D) (Andresen et al. 1994) captured the presence of depressive symptoms over the past 7 days. Responses range from 0 "rarely or never (less than 1 day)" to 3 "most or all of the time (5-7 days)". The CES-D total score ranges from 0 to 30, a cutoff score of ≥ 10 indicates the presence of clinically significant depressive symptoms (Andresen et al. 1994) .

Generalized Anxiety Disorder-7 The 7-item Generalized Anxiety Disorder-7 (GAD-7) screens for GAD symptoms occurring in the past 2 weeks (Spitzer et al. 2006) , with responses ranging from 0 "not at all" to 3 "nearly every day". The GAD-7 total score ranges from 0 to 21, a cutoff score of ≥ 10 indicates possible clinical levels of anxiety.

The 16-item Cambridge Worry Scale (CWS) (Statham et al. 1997 ) was used to assesses pregnancyspecific anxiety and general anxiety. Participants indicated the degree to which they worry about each item, on a scale of 0 ("not a worry") to 5 ("major worry").

The 7-item Insomnia Severity Index (ISI) (Bastien et al. 2001 ) measures sleep satisfaction, sleep interference, worry about sleep, and the severity of insomnia problems. The ISI total score ranges from 0 to 28; scores between 0 and 7 indicate no clinically significant insomnia, scores between 8 and 14 indicate subthreshold insomnia, and scores between 15 and 28 indicate clinical insomnia (moderate to severe severity).

The 10-item Perceived Stress Scale (PSS) assesses experiences of stress in the past month (Cohen and Williamson 1988) , with responses ranging from 1 "never" to 4 "very often." The PSS total score ranges from 0 to 40; scores between 0 and 13 indicate low stress, scores between 14 and 26 indicate moderate stress, and scores between 27 and 40 indicate high perceived stress (Cohen and Williamson 1988) .

Participants reported how they have been impacted by the COVID-19 pandemic (see specific items in Table 2 ). A single item captured the subjective overall impact of COVID-19; responses ranged from 1 (Very Positive) to 5 (Very Negative). In addition, six items ranging from 1 (Not at All) to 7 (A lot) were used to assess the financial difficulties and four dichotomous items (0 = No, 1 = Yes) captured social isolation resulting from COVID-19. Composites were created by averaging the financial difficulties items 1 and summing the isolation items. Given the small number of items on each scale, internal consistency was assessed using average inter-item correlations (Briggs and Cheek 1986; Herman 2015) (Table 2) .

The 28-item Brief Coping Strategies (Brief COPE) (Carver 1997 ) measured coping strategies used in response to the stress of COVID-19. Participants rated their use of each coping strategy on a scale ranging from 1 "I haven't been doing this at all" to 4 "I've being doing this a lot." In accordance with prior work (e.g., Chen et al. 2020; Cooper et al. 2008) , three Brief COPE subscales were created: dysfunctional coping (Denial, Venting, Self-Distraction, Substance Use, Behavioral Disengagement, and Self-Blame), problem-focused coping (Active Coping, Planning, and Using Instrumental Support), and emotion-focused coping (Using Emotional Support, Positive Reframing, Acceptance, Humor, and Religion).

Descriptive and correlation analyses were conducted using SPSS 26. Confirmatory factor analysis (CFA) was used to create a latent variable from the five mental health and distress questionnaire total scores. Structural equation mediation models (SEM) were conducted in Mplus Version 8 using full information maximum likelihood (FIML) and bootstrapping (with bias-corrected confidence intervals) to account for missing data (Fox 2015; Shrout and Bolger 2002) . Three SEM models tested the direct paths between the specific COVID-19 stressors (financial, isolation, subjective impact of COVID-19) on the mental health, and the indirect paths through (1) dysfunctional coping, (2) emotionfocused coping, and (3) problem-focused coping.

Covariates that had significant bivariate correlations with any mental health measure were entered in the final step of the modelling; covariates that significantly (p < 0.05) contributed to the model were retained. Model fit was assessed using the comparative fit index (CFI), Tucker-Lewis index (TLI), root mean squared error of approximation (RMSEA), and standardized root mean square residual (SRMR). Values equal to or greater than 0.95 for CFI and TLI and equal to or less than 0.08 for RMSEA and SRMR are considered indicative of good model fit (Schreiber et al. 2006) .

Missing data 0.3% (k = 1) of the CES-D, GAD, PSS, and Brief COPE, 1.0% (k = 3) of the ISI, and 2.0% (k = 6) of the CWS. None of the COVID-19 items was missing. Table 2 displays the descriptive statistics and psychometric properties for COVID-19 experiences, mental health, and coping measures.

The continuous items related to financial difficulties were averaged to compute a financial composite (M = 2.40, SD = 1.38) and the Table 2 ).

As shown in Table 3 , education, income, ethnicity, and number of children were significantly correlated with different mental health outcomes, and were tested as covariates in subsequent analyses.

As shown in Table 4 , the CFA measurement model had good model fit and all indicators loaded significantly onto the mental health latent variable. This latent variable was used as the outcome variable in subsequent SEM mediation analyses.

Subjective impact of COVID-19, coping, and mental health The SEM model examining the indirect paths from the subjective impact of COVID-19 to mental health via coping (dysfunctional, problem-focused, emotion-focused) demonstrated good model fit (Fig. 1 ). The final model included significant (p < 0.05) covariates (ethnicity and education). As shown in Fig. 1 , the subjective negative impact of COVID-19 was significantly associated with greater dysfunctional coping and less emotion-focused coping, but was not associated with problem-focused coping (a paths). Dysfunctional coping was positively associated with greater mental health severity and emotion-focused coping was negatively related to mental health (b paths). In addition, the association between the subject impact of COVID-19 and mental health remained significant after taking coping strategies into account (direct effect). Finally, the indirect effects through dysfunctional coping and emotion-focused coping were significant; the indirect path through problem-focused coping was not significant. This indicates that the subjective impact of COVID-19 is indirectly linked to increased mental health symptoms, through elevated dysfunctional coping and reduced emotion-focused coping.

COVID-19 financial difficulties, coping, and mental health The SEM model examining the indirect paths from COVID-19 financial difficulties to mental health via coping is shown in Fig. 2 . Greater financial difficulties were associated with more dysfunctional coping and problem-focused coping, but not emotion-focused coping. Only dysfunctional coping and emotion-focused coping were associated with mental health severity. Although there was not a significant direct association between COVID financial difficulties and mental health severity (Fig. 2) , indirect effects can occur in the absence of a direct effect (Hayes 2017) . Only the indirect effect through dysfunctional coping was significant (Fig. 2) .

Similarly, more social isolation was significantly associated with dysfunctional coping and problem-focused coping, and dysfunctional coping and emotion-focused coping were associated with mental health severity. Finally, COVID-related isolation was indirectly linked to increased mental health severity, through elevated dysfunctional coping, but not other forms of coping (Fig. 3 ).

To our knowledge, this is the first study to examine how coping strategies mediate associations between COVID-19 stressors and mental health problems during pregnancy. The findings demonstrate that (1) the perceived negative impact of COVID-19 as well as financial difficulties and social isolation resulting from COVID-19 are associated with distinct coping strategies; (2) coping strategies are linked to mental health; and (3) dysfunctional and emotion-focused coping strategies mediate the impact of COVID-19 experiences on mental health problems in pregnancy. Taken together, these findings indicate that coping is one pathway through which the pandemic is impacting mental health in pregnancy, highlighting a viable target for interventions aimed at minimizing the mental health consequences of COVID-19. The present findings are in line with the burgeoning literature, including several meta-analyses (e.g., Fan et al. 2020; Hessami et al. 2020; Sun et al. 2020; Yan et al. 2020) , which indicate that pregnant women are experiencing significant mental health problems during COVID-19. Specifically, 57% of the sample endorsed clinically elevated depression, 30% reported clinically elevated anxiety, 19% Table 3 Correlations between mental health symptoms, social support, and potential covariates In addition, the present findings underscore the importance of coping in the context of COVID-19. We found that particular COVID-19-related experiences were differentially associated with distinct forms of coping. Specifically, individuals who appraised the COVID-19 pandemic to have a greater negative impact engaged in more dysfunctional coping and less emotion-focused coping. In contrast, greater financial difficulties and social isolation were associated with more dysfunctional coping and problem-focused coping, but not emotion-focused coping. Negative cognitive appraisal represents a global index of the psychological impact of COVID-19, which might be more associated with coping strategies that target the emotional outcomes of COVID-19, as opposed to problem-focused coping which targets specific problems related to COVID-19. For example, someone who is feeling overwhelmed by the overall impact of COVID-19 might seek out emotional support from others, whereas someone who is experiencing financial strain resulting from the pandemic might plan ways of obtaining instrumental support (e.g., governmental assistance).

In line with prior research in pre-COVID pregnancy samples (e.g., Guardino and Dunkel Schetter 2014; Lau et al. 2016) , we found that dysfunctional coping was related to elevated mental health problems, emotion-focused coping was associated with less mental health problems, whereas problem-focused coping was not related to mental health. These findings add to the larger literature showing that specific coping strategies are associated with better/worse mental health outcomes during the COVID-19 pandemic (Jiang et al. 2020; Jungmann and Witthöft 2020) . For example, in a non-pregnant sample, global use of maladaptive coping strategies (i.e., withdrawal, blame, self-devaluation), measured before the pandemic, was associated with elevated stress and anxiety during the pandemic, whereas adaptive coping strategies were not associated with mental health problems (Brehl et al. 2021) . Prior work hypothesized that emotion-focused coping is more effective in the context of uncontrollable stressors, whereas problem-focused coping is more effective in response to controllable situations (e.g., Folkman and Moskowitz 2004) . Thus, it is possible that in the current study only emotion-focused coping was related to reduced mental health problems because of the uncontrollable nature of the COVID-19 pandemic.

Finally, the present findings indicate that dysfunctional and emotion-focused coping strategies act as mediators through which COVID-19 experiences are indirectly associated with mental health in pregnancy. These findings are in line with prior research with pregnant women, indicating that coping mediates associations between various stressful experiences and mental health problems (Choi et al. 2015; Greene et al. 2021; Giurgescu et al. 2006; Zhang et al. 2020) . Interestingly, some research shows that coping can also moderate the impact of stress on mental health Lau et al. 2014) . The present findings indicate that distinct coping strategies can be targeted to mitigate the effects of different COVID-19 experiences on mental health in pregnancy. Specific intervention targets can be prioritized depending on one's perceptions of the impact of COIVD-19 and the particular COVID-19-related stressors experienced. First, reducing the degree of dysfunctional coping (i.e., denial, disengagement, self-blame) may reduce the burden on mental health. Second, for individuals who perceive the global impact of COVID-19 to be more negative, engaging in more emotion-focused coping (e.g., seeking emotional support, positively reframing) can also reduce the impact on mental health. Taken together, promoting the use of adaptive coping strategies in place of dysfunctional coping strategies can help to ameliorate the effect of COVID-19 on mental health.

The COVID-19 pandemic likely affects the coping strategies that individuals are able to use. For example, ways of relieving stress and seeking emotional support, such as physical activity, attending counselling or support groups, and face-to-face contact with loved ones, have been altered during the pandemic. Indeed, a portion of the present sample was unable to access message therapy and counselling services, although the majority continued to have prenatal services (albeit remotely) (see Khoury et al. 2021 ). Related research shows that self-care activities, including exercise and mediation (Davenport et al. 2020; Deng et al. 2020) , as well as social support and access to support groups (Dib et al. 2020; Khoury et al. 2021) are associated with better mental health outcomes for pregnant women during COVID-19. Finding new ways of effectively coping during the pandemic is essential to positive mental health outcomes.

In addition, we found that greater mental health and distress symptoms were experienced by those who identified as non-White and who reported lower education and less income. This is in line with research indicating that ethnicminority status and financial stress predict elevated mental health problems in pregnant women during COVID-19 (Deng et al. 2020; Preis et al. 2021; Thayer and Gildner 2020) . Ethnic minorities and low-income individuals might experience greater stress as a result of COVID-19 (e.g., greater financial concerns) and have less access to particular coping strategies (e.g., internet access to have face-to-face virtual interactions). Therefore, public health initiatives must not only take these sociodemographic factors into account when identifying those at greatest risk of mental health outcomes but also ensure that a health equity-oriented lens is applied to any policy or clinical responses.

The present findings can be used to inform public health and mental health initiatives aimed at limiting the mental health consequences of COVID-19. Professionals working with pregnant women should inquire about different stressful experiences (financial strain, feelings of isolation, etc.), as well as the ways in which individuals typically cope with these stressors. Health care professionals can provide psychoeducation regarding the effectiveness of different coping strategies. Furthermore, an important aspect of intervention will be for individuals to learn when to apply different coping strategies based on the specific situational demands, as some situations might require an emotion-focused approach, whereas others require a problem-focused approach.

The limitations of this study should be considered. First, this is a cross-sectional study wherein we used a regression-based statistical approach to model mediation effects, which precludes any inference of causality. Although all measures were completed at a single time point, the coping measure was worded so that participants indicated how they were coping in response to the COVID-19 pandemic. However, it is possible that individuals' coping styles impact how they attribute COVID-19 stressors. Future longitudinal research is needed to ascertain temporal precedence between COVID-19 stressors and coping and mental health outcomes. Second, a convenience sample of participants was requited through social media and online questionnaires were used in this study. Future work is needed to determine whether results can be replicated with a more representative sample of the general population, using varied forms of assessments. Third, given the rapid onset of COVID-19, this is the first use of the COVID-19 Experience Scale in the published literature. Although we show acceptable internal consistency and validity, future research is needed to further establish the psychometric properties of this scale. Lastly, this is a socio-demographically low-risk sample, in that most participants were well educated and had higher income. This sample was also low risk in terms of health concerns related to COVID-19 and few participants were diagnosed with COVID-19. Future work is needed to determine whether similar coping strategies are used in response to COVID-19 stressors in more socio-demographically diverse samples who may be coping with greater health burden.

This study augments prior reports that pregnant women are experiencing elevated mental health problems in response to the COVID-19 pandemic. The present findings indicate that coping strategies are directly linked to mental health outcomes and that dysfunctional coping and emotion-focused coping mediate the associations between COVID-19 experiences and mental health outcomes in pregnancy. These findings highlight the need for widely available interventions to bolster adaptive coping skills in order to limit the mental health burden of pregnant women during the COVID-19 pandemic.
