Trait mindfulness facets as a protective factor for the development of postpartum depressive symptoms

Background: Postpartum depression has a prevalence rate of up to 17%. As there are many negative consequences of postpartum depressive symptoms, it is important to examine possible protective factors, such as trait mind-fulness. Since postpartum depressive symptoms are variable over time between and within individuals, this study focused on the possible association between facets of trait mindfulness and trajectories of postpartum depressive symptoms throughout the first postpartum year.Methods: A subsample of 713 women that participated in the HAPPY study completed the Three Facet Mind-fulness Questionnaire-Short Form at 22 weeks of pregnancy and the Edinburgh Postnatal Depression Scale (EPDS) at six weeks, four months, eight months, and twelve months postpartum. Possible different EPDS tra-jectories were obtained by means of growth mixture modeling.Results: Two EPDS trajectories (classes) were found: a low stable symptom class (N = 647, 90.7%) and an increasing-decreasing symptom class (N = 66, 9.3%). Women in the low stable class showed higher 'acting with awareness' and 'non-judging' scores. A higher score on the 'non-judging' facet of trait mindfulness was associated with a higher likelihood of belonging to the low stable class (OR = 0.79, 95% CI [0.72, 0.87], p < 0.001), adjusted for confounders and the other mindfulness facets. Conclusions: The non-judging facet of trait mindfulness was associated with low stable levels of depressive symptoms during the first postpartum year. Mindfulness-based programs, focusing on enhancing non-judging may be of benefit for pregnant women to possibly decrease the risk of developing postpartum depressive symptoms after childbirth.
