Abstract
Purpose: This study aimed to examine the interaction pattern of Psychological Strain and adverse early-life experiences with suicide probability in adolescents, considering the mediating effects of positive self-perception and feelings of entrapment.
The research method is descriptive-correlational, conducted using structural equation modelling (SEM). The statistical population of this study comprised all adolescents aged 13 to 19 in Nurabad (Delfan) County in the year 1403 (2024–2025).
Method: The study sample consisted of 623 adolescents from Nurabad (Delfan) County, selected through cluster random sampling. Data were collected using the Psychological Strain scale (Zhang et al., 2014), the suicide probability scale (Cull & Gill, 1982), the Entrapment Scale (Gilbert & Allan, 1998), the Early and Negative Life Experiences Scale (Gilbert et al., 2003), and the Positive self-perception subscale of the Multidimensional Suicide Inventory (MSI-28; Osman et al., 2010).
Findings: Early and negative life experiences, as well as psychological strain, accounted for 29% of the variance in positive self-perception and 50% of the variance in entrapment. Moreover, Psychological Strain, early and negative life experiences, positive self-perception, and entrapment together explained 56% of the variance in suicide probability.
Conclusion: Based on these results, it can be stated that fostering positive self-perception in schools and educating families, especially during critical developmental stages, is important for suicide prevention, as this factor plays a role in reducing suicidal behaviours.
