title: Self-mutilative behaviors in male substance-dependent inpatients and relationship with anger and aggression: mediator effect of childhood trauma.
abstract: The aim of this study was to investigate the relationship of self-mutilation (SM) with anger and aggression in male substance-dependent inpatients. Also, we wanted to evaluate the mediator effect of childhood trauma on these relationships while controlling variables such as age, substance of dependence (alcohol/drug), and negative effect. Participants were consecutively admitted 200 male substance-dependent inpatients. Patients were investigated with the Self-mutilative Behaviour Questionnaire, the Childhood Trauma Reports, the Buss-Perry's Aggression Questionnaire, the State-Trait Anger Expression Inventory, the Beck Depression Inventory, and the State-Trait Anxiety Inventory. Rate of being married, current age, and age onset of regular substance use were lower, whereas being unemployed and history of childhood trauma (HCT) were higher in group with SM (n = 124, or 62.0%). Higher mean scale scores were found in SM group. Predictors of SM were being younger, impaired anger control, and physical aggression in logistic regression model. Being younger and the outward expression of anger (anger-out) predicted SM in the subgroup of patients without HCT, whereas being younger, severity of anger, and the inward expression of anger (anger-in) predicted SM in the subgroup of patients with HCT. Thus, to reduce self-mutilative behavior among substance-dependent patients, clinicians must improve anger control, particularly in younger patients. Type of strategy for coping with anger, which must be worked on, may differ in different subgroup patients, that is, focusing anger toward self among those with HCT, whereas anger toward others among those without.
