Psychiatric and substance use disorders, separately or combined, are frequent in adolescence. Brief, psychometrically sound screening tools are needed to identify those at-risk. The Global Appraisal of Individual Needs-Short Screener (GAIN-SS) is a brief, inexpensive screener that was derived from the well researched full GAIN interview. However, its validity has not been independently investigated based on independent validated screening instruments in an adolescent clinical population. In this project, the internal consistency, validity, and optimal screening cutoff scores were examined in 95 adolescents, most of whom were receiving treatment, and suffered from internalizing (52%; n = 49), externalizing (66%, n = 63), and co-occurring substance use disorders (55%, n = 56). Results indicated adequate internal consistency and overall and subscale construct validity. Receiver operating characteristics (ROC) analyses revealed that the GSS substance use disorder subscale had adequate sensitivity (88%) and specificity (89%). Psychiatric disorder subscales performed less well. The discussion focuses on the strengths and potential weaknesses of use of the GSS and its potential utility in other populations.
精神疾病和物质使用障碍单独或合并出现的情况在青少年中很常见。需要简短且心理测量学上可靠的筛查工具来识别那些有风险的人。全球个体需求评估简筛工具（GAIN-SS）是一种简短、低成本的筛查工具，它源自经过充分研究的完整GAIN访谈。然而，其有效性尚未在青少年临床人群中基于独立验证的筛查工具进行独立调查。在本项目中，对95名青少年进行了内部一致性、有效性和最佳筛查临界值分数的检查，其中大多数青少年正在接受治疗，患有内化性疾病（52%；n = 49）、外化性疾病（66%，n = 63）以及同时存在物质使用障碍（55%，n = 56）。结果表明内部一致性良好，总体及各子量表的结构效度良好。受试者工作特征（ROC）分析显示，GSS物质使用障碍子量表具有足够的敏感性（88%）和特异性（89%）。精神疾病子量表的表现较差。讨论聚焦于GSS使用的优点和潜在缺点及其在其他人群中的潜在效用。
