Development of a model of self-harm behaviors based on cognitive strategies of emotional regulation in teenagers referring to DIC centers in Tehran: the mediating role of impulse control

The purpose of the present study was to predict self-harm behaviors based on cognitive strategies of emotional regulation with the mediating role of impulse control in adolescents referred to harm reduction centers in Tehran. This research was descriptive and correlational. The statistical population of the present study included adolescents aged 14 to 18 years who referred to temporary injury reduction centers in Tehran, district 12 (Shosh-Harandi neighborhood) in the first four months of 2022, which were selected using a simple random sampling method from among the adolescents who referred to 300 people were selected in these centers. Research tools included Self-Injury Questionnaire (SHI) (Sanson et al., 1998), Cognitive Emotion Regulation Questionnaire (CERQ) (Garnefsky et al., 2001) and Impulsivity Scale (BIS-11) (Barrett et al., 2004). The data were analyzed using the structural equation modeling method. The results of the present study showed that impulse control mediates the relationship between emotional cognitive regulation (B=0.39) and self-harm behaviors in adolescents. Also, according to the obtained values of RMSEA=0.048, CFI=0.99, GFI=0.99, cmin/df=1.81 and p-value=0.055, the model has a good fit.
