Aims: To examine whether there was any association between mothers' and fathers' post-partum depressive symptoms and sense of coherence and perception of their child's temperament. The hypotheses were that parents with depressive symptoms: 1) have more often a poor sense of coherence, and 2) perceive their child's temperament to be more difficult than parents without depressive symptoms. Methods: A total of 401 Swedish-speaking couples, who were the parents of children born through the years 2004-2006 in the northern part of the county of Vastmanland, Sweden, were invited to participate in the study. The parents answered 3 questionnaires including: at inclusion of the study: demographic data (n = 393 couples); at 3 months: the Edinburgh Postnatal Depression Scale and the Sense of Coherence Scale (n = 308 couples); and at 18 months: the Infant Characteristics Questionnaire (n = 272 couples). Results: Depressive symptoms measured at 3 months, were reported by 17.7% of mothers and 8.7% of fathers, and correlated significantly between mothers and fathers within couples (rho = 0.165, p = 0.003). Mothers and fathers with depressive symptoms had a poorer sense of coherence (p < 0.001, p < 0.001) and perceived their child's temperament as more difficult than mothers and fathers without depressive symptoms at 3 (p = 0.028, p < 0.001) and 18 months (p = 0.145, p = 0.012 respectively). Conclusions: Early parenthood has been studied thoroughly in mothers, but few studies have included fathers. Identifying problems in early parenthood could help predict later problems exhibited by the preschool child, which might be prevented by supportive programmes.
