Structural, concurrent, and predictive validity of the Substance Use Risk Profile Scale in early adolescence.

摘要

A brief personality risk profile (23 items), the Substance Use Risk Profile Scale was tested for concurrent and predictive validity for substance use in 1139 adolescents (grades 8-10) from a mid-sized city in western Canada. The SURPS was administered in two waves of a longitudinal study separated by 12 months (2003-04). As expected, four subscales were supported by confirmatory factor and metric invariance analysis. In regression analysis, three subscales, hopelessness, impulsivity, and sensation seeking, were positively related to current and future use; while one, anxiety sensitivity, was negatively related. Findings suggest clinical utility for screening adolescents at risk for substance use.
