However, to this date, it remains unclear whether there is a causal relation between depressive symptoms and this cognitive skill referred to as autobiographical memory coherence. For example, recent studies seem to suggest that the ability to narrate autobiographical memories in a coherent manner is impaired in individuals experiencing depressive symptoms. Various features of autobiographical memory have been shown to be compromised in individuals suffering from MDD. With an estimated 300 million people suffering from major depressive disorder (MDD) worldwide, research focusing on increasing insight into core processes of depression that can be targeted to prevent relapse, is of great importance. Different theoretical explanations are discussed. Results provided no support for the hypothesis that working memory capacity functioned as an underlying mechanism. This effect of mood on memory coherence was solely observed in female participants and not in the small male subsample. This increase was likewise observed in the positive mood group, though memory coherence remained consistent in the neutral mood group. Contrary to predictions, memory coherence increased following a negative mood induction. In addition, working memory capacity was expected to mediate the association between mood and memory coherence. We hypothesized that memory coherence would decrease following a negative mood induction. A group of 165 students were randomly allocated to one of three mood groups: negative, positive, and neutral. The current study aimed to examine the causal relation between mood and memory coherence by means of a mood induction paradigm. It remains, however, unclear whether a negative emotional state, one of the core symptoms of depression, causes this impairment in autobiographical memory coherence. Individuals who experience difficulty constructing coherent narratives about significant personal experiences generally report less psychological well-being and more depressive symptoms.
