Abstract

Purpose: The Symptom Checklist 90-Revised (SCL-90-R; Derogatis, 1992) is a widely used self-report measure of psychiatric symptoms (Prinz et al., 2013), but it is longer than many screening measures used in certain settings. Recently, a nine-item form of the SCL-90-R, the Symptom-Checklist-K-9 (SCL-K-9), has been gaining traction despite the limited research examining its psychometric properties in the United States. The purpose of this study is to conduct a psychometric evaluation of the SCL-K-9 scores in U.S. working-age adults with psychiatric disabilities.

Design: Six hundred and thirty participants with self-reported psychiatric disabilities completed the SCL-K-9 and other psychosocial self-report measures. Confirmatory factor analysis (CFA) was conducted to evaluate the SCL-K-9 scores' dimensionality. Coefficient omega was used to assess the scores' internal consistency. Convergent and discriminant validity were assessed by examining the strength and direction of correlation coefficients between the SCL-K-9 and other psychosocial measures. Measurement invariance across sex, age, and primary diagnostic groups was also examined.

Results: CFA revealed a one-factor solution with satisfactory reliability (coefficient omega = .828). Convergent validity was supported by the relatively high correlation coefficients between the SCL-K-9 with neuroticism, self-stigma, and psychiatric disability acceptance, and discriminant validity by relatively low correlation coefficients with perceived social stigma and hope. Full measurement invariance for sex and partial invariance for diagnostic groups was supported.

Conclusions: Overall, this study provides preliminary reliability and validity evidence for the SCL-K-9 scores among U.S. working-age adults with psychiatric disabilities. Further investigation is warranted to support its use for research and treatment progress monitoring in recovery-oriented care. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

症状检查表-K-9在美国有精神残疾的工作年龄成年人中的心理测量评估。

目的：症状自评量表90修订版（SCL-90-R；Derigions，1992）是一种广泛使用的精神症状自我报告指标（Prinz等人，2013），但它比某些情况下使用的许多筛查指标更长。最近，SCL-90-R的一种九项形式，症状检查表-K-9（SCL-K-9），尽管在美国对其心理测量特性的研究有限，但仍在获得关注。本研究的目的是对美国有精神残疾的工作年龄成年人的SCL-K-9评分进行心理测量评估。设计：630名自我报告有精神残疾的参与者完成了SCL-K-9和其他心理社会自我报告测量。采用验证性因子分析（CFA）对SCL-K-9评分的维度进行评价。系数omega用于评估分数的内部一致性。通过检查SCL-K-9和其他心理社会测量之间的相关系数的强度和方向来评估收敛有效性和判别有效性。还检查了性别、年龄和主要诊断组之间的测量不变性。结果：CFA揭示了一个具有令人满意的可靠性的单因素解决方案（系数ω=0.828）。SCL-K-9与神经质、自我污名和精神残疾接受之间相对较高的相关系数支持了收敛有效性，而与感知的社会污名和希望之间相对较低的相关系数则支持了判别有效性。支持性别的完全测量不变性和诊断组的部分不变性。结论：总体而言，本研究为美国有精神残疾的工作年龄成年人的SCL-K-9评分提供了初步的可靠性和有效性证据。有必要进行进一步的调查，以支持其在以康复为导向的护理中用于研究和治疗进展监测。（PsycInfo数据库记录（c）2023 APA，保留所有权利）。

期刊介绍： Rehabilitation Psychology is a quarterly peer-reviewed journal that publishes articles in furtherance of the mission of Division 22 (Rehabilitation Psychology) of the American Psychological Association and to advance the science and practice of rehabilitation psychology. Rehabilitation psychologists consider the entire network of biological, psychological, social, environmental, and political factors that affect the functioning of persons with disabilities or chronic illness. Given the breadth of rehabilitation psychology, the journal"s scope is broadly defined.
