本研究评估了物质使用风险量表（SURPS）的有效性、敏感性和特异性，SURPS是一种测量青少年物质使用和其他行为问题的人格风险因素的方法。方法采用线性回归和Logistic回归分析方法，对1,162名青少年（平均年龄13.7岁）进行SURPS的同时效度和预测效度检验，并采用受试者工作特征曲线分析方法检验其敏感性和特异性。结果同时效度和预测效度检验表明，绝望感（H）、焦虑敏感性（AS）、冲动性（IMP）和感觉寻求（SS）4个简明量表与物质使用和其他行为和情绪问题的测量均存在理论上预期的相关。结果还表明，当使用4个SURPS分量表来识别处于风险中的青少年时，可以识别出大量出现问题的青少年（高灵敏度评分范围为72%至91%）。而且，正如预测的那样，因为每个量表都与特定的物质和心理健康问题有关，所以当使用个体人格分量表时，获得了良好的特异性（例如，大多数通过IMP量表确定为高风险的青少年在接下来的18个月内出现了行为或药物使用问题[高特异性评分为70 - 80%]）。结论SURPS是一个有价值的工具，以确定青少年在高风险的物质滥用和其他情绪和行为问题。讨论了研究结果对未来研究和预防干预措施中使用该措施的影响。
Background This study assessed the validity, sensitivity, and specificity of the Substance Use Risk Profile Scale (SURPS), a measure of personality risk factors for substance use and other behavioral problems in adolescence. Methods The concurrent and predictive validity of the SURPS was tested in a sample of 1,162 adolescents (mean age: 13.7 years) using linear and logistic regressions, while its sensitivity and specificity were examined using the receiver operating characteristics curve analyses. Results Concurrent and predictive validity tests showed that all 4 brief scaleshopelessness (H), anxiety sensitivity (AS), impulsivity (IMP), and sensation seeking (SS)were related, in theoretically expected ways, to measures of substance use and other behavioral and emotional problems. Results also showed that when using the 4 SURPS subscales to identify adolescents at risk, one can identify a high number of those who developed problems (high sensitivity scores ranging from 72 to 91%). And, as predicted, because each scale is related to specific substance and mental health problems, good specificity was obtained when using the individual personality subscales (e.g., most adolescents identified at high risk by the IMP scale developed conduct or drug use problems within the next 18 months [a high specificity score of 70 to 80%]). Conclusions The SURPS is a valuable tool for identifying adolescents at high risk for substance misuse and other emotional and behavioral problems. Implications of findings for the use of this measure in future research and prevention interventions are discussed.
