This paper presents the psychometric evaluation of the Satisfaction with Life Scale (SWLS; Diener et al. in J Personal Assess 49:71-75, 1985) used with a large sample (N = 610) of caregivers for youth receiving mental health services. Methods from classical test theory, factor analysis, and item response theory were utilized. Additionally, this paper investigated whether caregiver strain mediates the effect of youth symptom severity on caregiver life satisfaction (N = 356). Bootstrapped confidence intervals were used to determine the significance of the mediated effects. Results indicated that the SWLS is a psychometrically sound instrument to be used with caregivers of clinically-referred youth. Mediation analyses found that the effect of youth symptom severity on caregiver life satisfaction was mediated by caregiver strain but that the mediation effect differed based on the type of youth symptoms: caregiver strain was a partial mediator when externalizing symptoms were measured and a full mediator when internalizing symptoms were measured. Implications for future research and clinical practice are discussed.
本文介绍了使用大量接受心理健康服务的青年照顾者样本（N=610）对生活满意度量表（SWLS；Diener 等人，J 个人评估 49:71-75,1985）进行心理计量评估的结果。本文采用了经典测试理论、因素分析和项目反应理论的方法。此外，本文还探讨了青少年症状严重程度对照顾者生活满意度的影响是否通过照顾者压力的中介作用（N=356）。使用自举置信区间确定中介效应的显著性。结果表明，SWLS 是一种具有心理计量学效度的工具，可用于临床转介的青年照顾者。中介分析发现，青少年症状严重程度对照顾者生活满意度的影响通过照顾者压力来介导，但这种中介效应取决于青少年症状的类型：当测量外显症状时，照顾者压力是部分中介，而当测量内隐症状时，照顾者压力是完全中介。本文讨论了对未来研究和临床实践的影响。
