The effects of borderline personality and sociodemographic traits on self-harm and suicidal behavior in substance use disorder

Objectives: Borderline personality traits (BPT), which have a negative effect on the prognosis in substance use disorder (SUD), may increase the frequency of self-harming behavior (SHB) and suicidal behavior (SB). A determination of BPT may be a protective measure against SHB and SB. The objective of this study was to analyze the predictive role of BPT on SHB and SB in individuals diagnosed with SUD. The participants' sociodemographic data were also analyzed for contribution to the context. Methods: This cross-sectional research was conducted with inpatients at a single, private hospital psychiatric ward who had been diagnosed with SUD (n=122). The data were collected using the Borderline Personality Inventory, the Inventory of Statements About Self-Injury, and the Suicidal Behaviors Questionnaire. Results: The results demonstrated a predictive role of BPT and gender on SHB in individuals diagnosed with SUD. BPT, socioeconomic status, and education were found to be predictors of SB in individuals diagnosed with SUD. Conclusion: The results of the research demonstrated that the risk evaluation of SHB and SB in SUD is highly significant. BPT must be handled independently from substance abuse with the appropriate psychological interventions. The findings also indicated that the education and socioeconomic level of the patient were significant factors and that psychosocial support is essential for this high-risk group. Additional research could provide valuable information that would enable more efficient, targeted treatment strategies.
