Final answer:
Arturo's experience with depression and low self-confidence, influenced by his parents' negative remarks during his childhood, aligns with the cognitive model of abnormality. This model focuses on negative thinking patterns and maladaptive beliefs as key factors in depression, consistent with studies by researchers like Aaron Beck and the reformulations presented by Seligman in the hopelessness theory.
Step-by-step explanation:
Based on the information provided about Arturo, who experiences periods of moderate to severe depression and lacks self-confidence due to childhood experiences with his parents, the model of abnormality that is MOST likely to describe his situation is the cognitive model. This model emphasizes the role of negative thinking and maladaptive belief systems as underlying causes of depression. According to Aaron Beck and the developments in cognitive theory, patterns of thought concerning oneself, the world, and the future can contribute to depressive symptoms. The reformulated theory of learned helplessness, now known as hopelessness theory, also suggests that individuals may develop depression when they perceive a lack of control over stressful events and make internal, stable, and global attributions for negative life events, as highlighted in the studies by Peterson and Seligman.
Arturo's statement about his self-perception, which was negatively influenced by his parents, aligns with the idea that cognitive processes, particularly those involving self-assessment and attribution styles, play a significant role in the development and maintenance of depression. Therefore, understanding and addressing these cognitive factors could be crucial in Arturo's therapeutic intervention.
