Abstract

This study aimed to investigate the serial pattern of psychological strain and early adverse life experiences with the suicide probability in adolescents due to the mediating role of depression and rumination.

Method: The research method was descriptive-correlational,.The statistical population of this study consisted of all adolescents aged 14 to 19 years in Lorestan province in 2024. The sample consisted of 623 adolescents in Lorestan province who were selected by random cluster sampling method and answered the questions of the Psychological Stress Scale Short Form Questionnaire (PSS Siau et al., 2024), Early Life Experiences (Gilbert & Allen, 1998), Hospital Depression and Anxiety Scale (HADS, Zigmond, & Snaith, 1983), and Rumination Questionnaire Short Form (O'Connor & Williams, 2014). The results obtained from the structural equation modeling in the overall model and based on gender had a good fit. The results from the gender moderator analysis showed that in girls, early adverse life experiences have a direct positive and significant effect on depression, rumination and the suicidal probability (P< 0.05). Moreover, psychological strain has a direct positive and significant effect on depression, rumination, and the suicidal probability (P> 0.05).

Conclusion: The present study, considering the theory of psychological strain and early adverse life and disturbing experiences, provides a unique conceptual and theoretical framework to identify the antecedents of suicide risk in adolescents based on depression and rumination before committing suicidal behavior and attempts.
