This article describes the results of psychometric work conducted on the Comprehensive Adolescent Severity Inventory (CASI) among 205 in-treatment substance-abusing adolescents. Four dimensions, each composed of component subscales, resulted from standard psychometric analyses: Chemical Dependency, Psychosocial Functioning, Delinquency, and Risk Behavior. Each dimension had high internal consistency (alpha coefficients for the component subscales comprising each clinical dimension range from .78 to .96) and test-retest reliability (intraclass correlation coefficients range from .88 to .96 and all are significant at p < .0001.). Concurrent validity and specificity of the CASI dimensions also were found: significant and substantial variance in NIMH Diagnostic Interview Schedule for Children-Revised (DISC-IV) and Brief Symptom Inventory (BSI) scores was associated with relevant CASI dimensions; CASI dimensions that theoretically should show no significant relationship with divergent pathology were not associated. The dimensions forecasted substantial variance in adolescent functioning posttreatment discharge, supporting predictive validity. Finally, the dimensional clinical structure was found to be generalizable over male and female adolescents, younger and older adolescents, and adolescents from different ethnic groups. These results provide further evidence for the CASI's promise in research and practice as an adolescent-specific assessment instrument that comprehensively assesses multidimensional areas of functioning within a developmental context of measurement. Limitations of the study along with future work currently being conducted on the CASI are discussed.
本文描述了对205名接受治疗的药物滥用青少年进行的综合青少年严重程度量表(CASI)心理测量工作的结果。标准心理测量分析得出了四个维度,每个维度由组成性子量表构成:化学依赖、心理社会功能、犯罪行为和风险行为。每个维度都具有较高的内部一致性(构成每个临床维度的子量表的alpha系数范围为0.78至0.96)和重测信度(组内相关系数范围为0.88至0.96,且在p < 0.0001时均具有显著性)。还发现了CASI维度的同时效度和特异性:儿童诊断访谈量表修订版(DISC-IV)和简明症状量表(BSI)得分的显著且实质性差异与相关的CASI维度相关;理论上应与不同病理学无显著关系的CASI维度则不相关。这些维度预测了青少年治疗后出院时功能的实质性差异,支持了预测效度。最后,发现维度临床结构在男性和女性青少年、年龄较小和较大的青少年以及不同种族的青少年中具有普遍性。这些结果为CASI作为一种针对青少年的评估工具在研究和实践中的前景提供了进一步的证据,该工具在测量的发展背景下全面评估功能的多个维度。讨论了该研究的局限性以及目前正在对CASI进行的未来工作。
