Clinical and psychological predictors of non-suicidal self-injurious behavior in individuals of draft age with addictive disorders

Objective. To examine the types of addictive disorders and the prevalence of non-suicidal self-injurious behavior (NSIB) among individuals of military age, while identifying clinical and psychological predictors of non-suicidal self-injuries. Material and methods. In total, 138 young individuals of military age (18—30 years, median age 25.5 years) diagnosed with addictive disorders were assessed. Several clinical, psychopathological, and psychometric assessment tools were utilized, including the Five Factor Personality Questionnaire (5PFQ), the Buss and Perry Aggression Questionnaire (BPAQ), the Beck Anxiety Inventory (Beck-A), the Beck Depression Inventory (Beck-D), and the Self-Injurious Behavior Questionnaire. The statistical analysis included χ2 tests, the Mann—Whitney U test, and multiple logistic regression. Results. The prevalence of NSIB in the clinical group was 37.7%. The types of addictive disorders included F10.2 (26%), F19.2 (21%), F11.2 (13.7%), F12.1 (12.4%), F19.1 (8.7%), and F10.1 (5.8%). Individuals with NSIB demonstrated an earlier onset of substance use, elevated scores on anxiety and depression scales, increased aggression, low self-esteem, and a distinct personality profile characterized by high neuroticism and low conscientiousness. The logistic regression model identified several clinical and psychological predictors of NSIB: neuroticism (odds ratio [OR]=1.63), suicidal ideation (OR=4.00), anxiety levels (OR=1.11), early onset of substance use (OR=0.83), dysfunctional family relationships (OR=2.64), and the specific nature of the addiction (polydrug addiction; OR=2.44). This model explains 49.6% of the variability (Nagelkerke R2). Conclusions. Self-destructive behavior among individuals of military age with addictive disorders serves as an indicator of a severe comorbid course and is associated with a specific personality profile, elevated affective tension, and a negative family environment. The identified predictors highlight the need for proactive screening for NSIB and the development of targeted programs to address emotional regulation and impulsivity in this clinical population.
