Spanish version of the Substance Use Risk Profile Scale: Factor structure, reliability, and validity in Mexican adolescents

To validate the Substance Use Risk Profile Scale (SURPS) in a sample of Mexican adolescents, this brief 23-item self-report questionnaire has been developed to screen four high-risk personality traits for substance misuse, to guide targeted approaches to prevention of addictions in adolescents. The scale has been previously validated in United Kingdom, Canada, Sri Lanka and China. A sample of 671 adolescents aged 11-17 completed a Spanish translation of the SURPS as well as other measures of personality and substance use. The Spanish translation of the SURPS has moderate internal consistency, and demonstrated a four-factor structure very similar to the original scale. The four subscales show good concurrent validity and three of the subscales were found to correlate with measures of substance use. The Spanish translation of the SURPS seems to be a valid and sensitive scale that can be used in a Mexican adolescent population.
