The purpose of the current study was to explore psychopathology as a mediator of quality of life (QOL) in children and adolescents with obesity. The notion that psychopathology and QOL are two distinct constructs was also tested.
A sample of treatment-seeking children and adolescents with obesity (n = 185, average age = 11.5, mean BMI SDS = 3.03) was matched to a community sample of children (n = 799, average age = 11.5). Both self- and parent-reported measures of QOL (KINDL-R) and psychopathology (CBCL/YSR) was completed.
Parent-reported QOL was impaired, and both self-reported and parent-reported psychopathology was elevated in children and adolescents with obesity. Psychopathology accounted for all the variance of the effect of obesity on parent-reported QOL. The distinction between QOL and psychopathology was supported through confirmatory factor analysis.
Impaired parent-reported QOL in children and adolescents with obesity was attributable to their elevated levels of psychopathology.
本研究旨在探讨精神病理学在肥胖儿童和青少年生活质量（QOL）中的中介作用。同时还测试了精神病理学和 QOL 是两个不同的概念这一假设。
对 185 名接受治疗的肥胖儿童和青少年（平均年龄=11.5 岁，平均 BMI SDS=3.03）进行了样本匹配，与儿童社区样本（n=799，平均年龄=11.5 岁）进行了比较。完成了自我报告和父母报告的 QOL（KINDL-R）和精神病理学（CBCL/YSR）的评估。
肥胖儿童和青少年的父母报告的 QOL 受损，且自我报告和父母报告的精神病理学均升高。精神病理学解释了肥胖对父母报告的 QOL 的影响的所有差异。通过验证性因子分析支持了 QOL 和精神病理学之间的区别。
肥胖儿童和青少年父母报告的 QOL 受损归因于他们较高的精神病理学水平。
