Validation of the Substance Use Risk Profile Scale in Lithuanian population

Abstract

Abstract Background Personality traits are related with risk of hazardous alcohol use and alcohol dependence. The Substance Use Risk Profile Scale (SURPS) measures personality traits associated with addictive substance abuse. We examined psychometric properties of the SURPS in Lithuanian population. Materials and methods Two hundred forty-seven participants (mean age 37.22 ± 0.78 years), were recruited from the local community and from an inpatient addiction treatment centre. Internal consistency, stability, factor structure, content validity, and external validity of the SURPS were examined. Hazardous alcohol use was evaluated by Alcohol Use Disorder Identification Test (AUDIT). Alcohol dependence diagnosis was established by International Classification of Diseases - 10 (ICD - 10). We also performed gender analyses for associations of personality traits with alcohol dependence and hazardous use of alcohol. Results The SURPS scale demonstrated appropriate internal validity, good temporal stability, and adequate criterion validity and construct validity. The SURPS scores of hopelessness, anxiety sensitivity and impulsivity were higher in the alcohol dependence group than in the control group for both males and females. Impulsivity and sensation seeking were associated with hazardous alcohol use and these associations were more prevalent in females. Conclusions Lithuanian translation of the SURPS scale was appropriate. The SURPS demonstrated good sensitivity for discriminating on alcohol dependence and was more sensitive for discriminating on hazardous alcohol use for females.
