Abstract

Suicide stands as one of the leading causes of non-accidental death among adolescents and young adults. The Integrated Motivational-Volitional Model (IMV) of suicidal behavior identifies feelings of defeat and entrapment as pivotal factors in the complex dynamics underlying suicidal behaviors. Additionally, depressive symptomatology plays a crucial role in the development of these behaviors. The aim of this work was to provide a systematic review of the scientific literature on the association of three risk factors-entrapment, defeat, and depressive symptomatology-with suicidal ideation in the adolescent and young adult population and to test a tentative theoretical model. The databases used were PubMed, Web of Science, and ProQuest. Primary studies were selected that examined the role of entrapment, defeat, and depressive symptomatology in suicidal ideation among adolescents and young adults (ages 10-35). Additionally, a model based on structural equation modeling was analyzed to assess the relationships between entrapment, defeat, and depressive symptomatology and suicidal ideation. Eleven studies met the established inclusion criteria. The results showed defeat and entrapment to be associated with depressive symptomatology and suicidal ideation, regardless of the country studied. Additionally, the model indicates that entrapment and defeat lead to depressive symptomatology, which in turn contributes to the occurrence of suicidal ideation. These findings suggest that defeat and entrapment could be universal factors in explaining suicidal behavior in adolescents and young adults. Consequently, the results of this work may contribute to the development of strategies for preventing suicidal ideation in this population.
