Abstract
This article highlights how the many important contributions of John R. Z. Abela's research program can inform the development and implementation of interventions for preventing depression in youth. Abela provided evidence of multiple vulnerabilities to depression including cognitive (e.g., inferential style, dysfunctional attitudes, ruminative response style), interpersonal (e.g., reassurance seeking, attachment, dependency), personality (e.g., neuroticism, self-criticism), and contextual (e.g., stress, parental depression). He introduced important methodological advances to the study of the hopelessness model of depression, especially in children, including the "weakest link" approach, cognitive priming, and idiographic measurement of stress. We briefly review what is currently known about the prevention of depression regarding intervention targets, content, outcomes, effect sizes, moderators, mediators, specificity, and durability. Next, we summarize several of Abela's contributions that are most relevant to the prevention of depression. We describe the implications of Abela's work for the development, implementation, and testing of programs aimed at preventing depression and discuss important challenges such as the transfer of training to and the personalization of interventions so as to capitalize on individuals' strengths versus compensate for their weaknesses.
