As to the associations between personality traits and anxiety or depression, research has mostly been conducted in men and nonpregnant women (Klein et al. 2010; Kotov al, 2010). We observed in our study that both high neuroticism and low extraversion are associated with increasing levels of both antenatal anxiety and depression, not contradicting our hypothesis that during pregnancy the associations of these traits with antenatal anxiety and depression are different (Kinsley and Amory-Meyer, 2011) We further hypothesised that the association between life events during pregnancy and the change in symptoms of antenatal anxiety or depression is modified by traits or childhood trauma.However, none of the pertaining interactions were substantial or significant. This is contrary to our expectations,Spinhoven et al. (2010) considered neurdticism as a mcdifier: however, they studied this personality trait as a modifier in the association between childhood trauma and anxiety or depressive disorders, whereas we considered childhood trauma to be an effect modifier itself. In addition, our study did not consider disorders but sub-syndromal symptoms.
