Validity and reliability of Chinese version of 28-item Substance Use Risk Profile Scale in Chinese adolescents and young adults

The present study aimed to explore the validity and reliability of the Chinese version of the 28-item Substance Use Risk Profile Scale (SURPS) and provide an effective assessment tool for personalities related to substance use by which to predict and intervene in substance use cases. A total of 2114 Chinese adolescents and young adults (age 19.44 ± 1.63 years old) were enrolled. The results showed that the modified SURPS-SL_r model fit well (χ2/df = 5.15, p < 0.01, CFI = 0.851, TLI = 0.835, RMSEA = 0.037, SRMR = 0.063), indicating that the structure of the SURPS was suitable for Chinese adolescents and young adults. The SURPS significantly correlated with the Satisfaction with Life Scale, Subjective Health Complaints Index, Beck Depression Inventory, Zuckerman-Kuhlman Personality Questionnaire, and Neuroticism Extraversion Openness Five-Factor Inventory (r = 0.22 ~ 0.60, all ps < 0.01), indicating that the criterion validity of the SURPS was good. The Cronbach’s α of SURPS and its dimensions were 0.74~0.83, which suggested the SURPS has good reliability. Therefore, the Chinese version of the 28-item SURPS is an effective and reliable measure of personalities linked to substance use in Chinese adolescents and young adults.
