The role of cognitive schemas and childhood adversity in the likelihood of developing Major Depressive Disorder

Abstract

Introduction/objective: Major Depressive Disorder (MDD) is a multifactorial mental health disorder. Stressful events and childhood abuse have been included in different models to explain its etiology. However, little evidence is available on how attributional style and early maladaptive schemas are related to MDD. Method: A retrospective case-control study using a three-stage hierarchical logistic model was conducted to explore the relationship between MDD and psychosocial variables such as childhood adversity, stressful life events, attributional style, and cognitive schemas in a sample of 171 individuals with a current depressive episode and 171 healthy controls. Results: Depression could be predicted by childhood adversity, an attributional style characterized by interpreting stressful events as negative and uncontrollable and the cognitive schemas in impaired autonomy/performance domains and impaired limits. Conclusions: Our results highlight the relevance of identifying cognitive factors, beyond clinical symptoms that could be useful to better understand MDD. These findings may result in better preventive programs and create awareness of the role of cognitive domains in MDD.
