Schools are increasingly concerned with the well-being of the whole child - likely, more so since the COVID-19 pandemic - and goals here were to document the psychometric properties of a brief new measure of adolescent mental health, the Well-Being Index (WBI). The measure assesses 4 symptom areas, 2 each of internalizing and externalizing symptoms-Depression, Anxiety, Rule-Breaking, and Substance Use-and an optional scale on Isolation at School. A total of 2,444 students from 2 high schools completed the WBI, the Youth Self-Report (YSR), and other related measures. Alpha coefficients showed acceptable internal consistency, with values for the 5 WBI subscales at .83, .84, .78, .79, and .74, respectively. Both exploratory and confirmatory factor analyses demonstrated consistent factorial validity. Correlations with corresponding YSR subscales indicated good convergent and discriminant validity. The WBI Substance Use and Isolation at School subscales, similarly, had high correlations with subscales from preexisting measures. Criterion-related validity was indicated in significant correlations between WBI subscales and conceptually related dimensions of close relationships. Also examined was the percentage of youth falling above clinical cutoffs on both the WBI and YSR, and findings demonstrated high concurrent validity. Collectively, results suggest the promise of the WBI as a brief, psychometrically sound measure to assess the adjustment of adolescents, along with perceptions of school climate that can be modified toward fostering their overall well-being.

学校的幸福指数（WBI）：青少年心理健康的简要衡量指标。

学校越来越关注整个孩子的幸福感-自COVID-19大流行以来可能更是如此-并且这里的目标是记录青少年心理健康的一项简短新指标-幸福感指数（ WBI）。这项措施评估了4个症状区域，其中2个是内在和外在症状-抑郁，焦虑，违反规则和物质使用-以及学校隔离的可选等级。来自2所中学的2444名学生完成了WBI，青年自我报告（YSR）和其他相关措施。Alpha系数显示出可接受的内部一致性，这5个WBI分量表的值分别为.83，.84，.78，.79和.74。探索性和确认性因子分析均显示出一致的因子有效性。与相应的YSR分量表的相关性表明了良好的收敛性和判别力。同样，WBI在学校中的物质使用和隔离量表与已有措施中的量表具有高度相关性。与标准相关的有效性在WBI分量表与紧密关系的概念相关维度之间具有显着相关性。还检查了在WBI和YSR上均超过临床临界值的年轻人的百分比，研究结果表明，并发有效性很高。总的来说，研究结果表明，WBI有望作为一种简短的，从心理上讲是合理的措施来评估青少年的适应能力，以及对学校气候的看法，可以改变这些看法以促进他们的整体福祉。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
