Inhibition and Activation Systems of Behavior and Suicide Mediating Role of Cognitive Emotion Regulation.

Objective: This study aimed to predict suicide attempts based on behavioral activation and inhibition systems (BAS/BIS) with the mediating role of cognitive emotion regulation (CER) strategies among adolescents of Abyek City. Materials and methods: The research methodology was descriptive-correlational. The cluster sampling method was used, and the resulting sample included 194 adolescents who responded to the BAS/BIS questionnaire (Carver & White, 1994), CER questionnaire, and Beck scale for suicide ideation. Path analysis was employed to evaluate the proposed model using AMOS 24.0 and SPSS 27 softwares. Results: The findings indicate that the proposed model is fitted with the data well. The results of path analysis showed that the BAS/BIS systems explain 27% of the variance of maladaptive CER and 61% of the variance of adaptive CER. In addition, maladaptive CER, BAS, and BIS explain 65% of the variance of suicide attempts. Conclusion: Low levels of BAS, high levels of BIS, and the use of maladaptive CER skills can be considered risk factors for suicide attempts in adolescents.

The Structural Model of the Effects of Psychological Strain, Defeat, and Thwarted Belongingness on Suicidal Ideation in Adolescents via the Mediation of Depression and Hopelessness.

OBJECTIVE: This study aimed to identify factors associated with suicidal ideation (SI) in adolescents and to explore the mediating role of depression and hopelessness in these predictive relationships. METHOD: Employing a cross-sectional research design, this study included adolescents aged 14 to 19 from Lorestan Province in Iran. A total of 623 middle-school students were selected through a multi-stage cluster sampling technique. Data were collected using a series of assessment tools, including the Depressive Symptom Index-Suicidality Subscale (DSI-SS), the Psychological Strain Questionnaire, the Hopelessness Scale, the Defeat Scale, and the Thwarted Belongingness Questionnaire. Structural Equation Modeling (SEM) in AMOS version 26 and SPSS version 26 was utilized to evaluate the proposed model. RESULTS: The findings revealed that in the context of Iranian adolescents, defeat and psychological strains emerge as significant predictors of SI. Notably, hopelessness was found to mediate the relationship between psychological strains, defeat, and SI. CONCLUSION: These insights provide valuable knowledge for addressing the issue of SI in Iranian adolescents and may inform future prevention and intervention strategies.
