BACKGROUND:Perinatal depression is reported in 15-20% of women (Marcus, 2009), 8-16% of men (Paulson and Bazemore, 2010) and low-SES, diverse populations are particularly at risk (Sareen, 2011). Trauma symptoms are commonly comorbid with depression, especially when individuals are exposed to risk factors such as community violence and poverty (Kastello et al., 2015; WenzGross et al., 2016). Parental mental illness places infants at risk for negative outcomes (Junge et al., 2016). Evidence supports that dispositional mindfulness is linked to mental health in many populations, however, a gap lies in the understanding of the relationship between mindfulness, trauma and depression in risk-exposed, pregnant populations, especially with fathers. We hypothesize that dispositional mindfulness is negatively associated with lower depression and trauma symptoms in pregnancy, in mothers and fathers. METHODS: Dispositional mindfulness, depressive and trauma symptoms were examined in women and men, exposed to adversity who were expecting a baby (N = 102). Independent t-tests, and bivariate correlations examined the relationships between these variables. Hierarchical regression was utilized to understand how mindfulness and trauma symptoms may contribute to antenatal depression symptoms. RESULTS: Significant differences were observed with mindfulness and depressive symptoms, with no differences reported across gender. Mindfulness, depressive and trauma symptoms were associated in the expected directions. Total mindfulness, specifically being non-reactive to one's own thoughts and trauma symptoms predicted depressive symptoms. LIMITATIONS: Limitations include small sample size, cross-sectional data and self-report measures. CONCLUSION: Mindfulness and trauma symptoms were found to be significant predictors of depressive symptoms in parents-to-be. Those with lower mindfulness exhibited higher levels of depression. These findings may be helpful in disseminated mindfulness-based interventions aimed at treating antenatal depression in both expectant mothers and fathers who are exposed to adversity. Further research is necessary to understand the mechanisms of mindfulness in risk-exposed, expectant parents.
