Researchers have demonstrated that quality of life (QOL) is an important construct to measure in individuals with mental health disorders, yet only a small amount of research has been dedicated to examining QOL and its response to treatment in children and adolescents with obsessive-compulsive disorder (OCD). The current study explored the psychometric properties of a measure of QOL, the Pediatric Quality of Life Enjoyment and Satisfaction Questionnaire (PQ-LES-Q), by examining the reliability, validity, and treatment sensitivity of this measure delivered in two separate RCTs for OCD (total N = 251 across both studies). Our results provide evidence for the reliability and validity of the PQ-LES-Q in adolescents with OCD (all Cronbach's alphas >.89, convergent validity correlations significant at the p < .05 level), but that an adaptation of the measure many be necessary for valid use in younger children with OCD.
研究人员已经证明，生活质量（QOL）是衡量心理健康障碍患者的一个重要指标，但仅有少量研究致力于考察强迫症（OCD）儿童和青少年的生活质量及其对治疗的反应。本研究通过在两项针对强迫症的独立随机对照试验（两项研究的总样本量N = 251）中检验生活质量量表——儿童生活质量享受与满意度问卷（PQ - LES - Q）的信度、效度和治疗敏感性，探讨了该量表的心理测量学特性。我们的研究结果为PQ - LES - Q在青少年强迫症患者中的信度和效度提供了证据（所有克隆巴赫α系数>.89，收敛效度相关性在p <.05水平上显著），但可能需要对该量表进行调整，以便在患有强迫症的年幼儿童中有效使用。
