Psycho-Socio-Demographic Risk Factors of Self-injurious Behaviors in Iranian Females Inmates: A Case-Control Study

Background: Self-injurious behavior or self-harm among inmates is a common phenomenon. However, no study has yet been conducted in Iran regarding self-harm in female inmates. Objectives: The present study aimed to investigate the psycho-socio-demographic risk factors associated with non-suicidal self-harm in Iranian female inmates. Patients and Methods: Participants in this case-control study were 306 female inmates in Tehran, who were randomly selected and divided into two groups: (1) 88 individuals who scored 5 or higher on the Sansone Self-harm Inventory (SHI), and (2) 88 individuals randomly selected from the 218 inmates who did not self-harm as the comparison group. The participants completed a researcher-designed questionnaire, SHI, and the Difficulties in Emotion Regulation Scale. The data were analyzed using logistic regression analysis in SPSS version 16. Results: Logistic regression analysis revealed that marital status (B = 1.438, P = 0.002), arrest history (B = 1.295, P = 0.005), substance abuse (B = 1.198, P = 0.011), psychiatric diagnoses (B = 1.126, P = 0.018), parental divorce (B = 1.280, P = 0.005), and difficulties in emotion regulation (B = 0.027, P = 0.022) were significant predictors of self-harm in inmates. Although there was a difference in the addiction rates of parents between those with self-harm and those without, this variable did not predict self-harm in female inmates (B = 0.488, P = 0.307). Conclusions: The results of this study underscore the importance of family-based preventive interventions to prevent self-harm behaviors among female inmates.
