Self-esteem fully mediates positive life events and depressive symptoms in a sample of 173 patients with affective disorders.

OBJECTIVES: Previous research showed that positive and negative life events influence the development of depression. However, it is less clear how life events interact with depressive symptoms and self-esteem. DESIGN AND METHODS: The present study aimed to investigate the mediating effects of self-esteem on the relationship between life events and depressive symptoms in adulthood. The Traumatic Antecedent Questionnaire, Multidimensional Self-esteem Scale (MSWS), and Becks Depression Inventory were administered in 173 psychiatric inpatients (mean age 39.69 ± 14.56 years, ranging from 18 to 76 years). At the time of assessment, all patients suffered from depressive symptoms caused by an affective disorder (major depression, bipolar I, dysthymia). RESULTS: Path analyses showed that the individual level of self-esteem (measured by MSWS) fully mediated the association between positive life events and depressive symptoms. CONCLUSIONS: The current study indicates that future therapy programmes for patients with depressive symptoms could include interventions focusing on the improvement of self-esteem, as increasing self-esteem may be beneficial for recovery. PRACTITIONER POINTS: To date, this is the first study exploring the pathways from positive/negative life events to depressive symptoms. The relationship between positive life experiences and depressive symptoms was fully mediated by self-esteem. Strengthening self-esteem in therapy might lower the vulnerability for depression.

The Role of Self-Esteem in Depression: A Longitudinal Study.

BACKGROUND: Based on the vulnerability model, several studies indicate that low self-esteem seems to contribute to depressive symptoms. AIMS: The aim of this study was to treat depressive symptoms in a cognitive behavioural group therapy, focusing on the enhancement of self-esteem, and to explore co-variation in depressive symptoms and the level of self-esteem. METHOD: The Multidimensional Self-esteem Scale (MSWS) and the Beck Depression Inventory (BDI) were administered to 147 psychiatric in-patients with current depressive symptoms due to an affective disorder (major depression, bipolar I, dysthymia). Self-esteem was measured pre-treatment (t0) and post-treatment (t4, after 5 weeks of eight group sessions); the BDI was applied weekly. A linear mixed growth analysis was conducted to estimate the change in depressive symptoms including interactions with self-esteem. RESULTS: Within the 5 weeks of group therapy, depressive symptoms showed a linear decline, which was stronger for patients with higher gains in self-esteem between t0 and t4. Self-esteem at t0 was unrelated to the change in depression but predicted self-esteem at t4. CONCLUSIONS: Treating depressive symptoms in a cognitive behavioural group therapy in a naturalistic setting might have a positive effect on the process of recovery. Moreover, depressive symptoms and level of self-esteem seemed to co-vary.
