目的：评价一种新的多元文化体重特异性生活质量测量工具--青少年生活质量量表-体重模块（YQOL-W）的心理测量学特性。对443名11至18岁的儿童和青少年进行了25项候选项目的调查，其中53%为女性，33%为白色，30%为非洲裔美国人，37%为墨西哥裔美国人。34%的人身体质量指数（BMI）健康，20%超重，46%肥胖。最初的25个候选项目中有21个保留在最后文书中。探索性和验证性因素分析（CFA）得到一个单因素（21项，α = 0.97）和三因素模型，包括自我因素（4项，α = 0.90），社会因素（11项，α = 0.95）和环境因素（5项，α = 0.90）。验证性因素分析发现三因素模型拟合效果较好（P < 0.05）。单因子分和三因子分均与BMI、儿童抑郁量表呈负相关，与一般生活质量呈正相关，均P < 0.05。1周重测的班级内相关系数分别为：社会、自我、环境和单因素模型的相关系数分别为0.73、0.71、0.73和0.77。YQOL-W在儿童和青少年中显示出良好的信度和效度。
To evaluate the psychometric properties of a new multicultural weight-specific quality-of-life (QOL) measure for children and adolescents–Youth Quality-of-Life Instrument–Weight module (YQOL-W). Twenty-five candidate items were administered to 443 children and adolescents between 11 and 18 years of age, of whom 53% were female, 33% were white, 30% were African American and 37% were Mexican American. Thirty-four percent had a healthy body mass index (BMI), 20% were overweight and 46% were obese. Twenty-one of the original 25 candidate items were retained in the final instrument. Exploratory and confirmatory factor analyses (CFA) resulted in a one-factor (21 items, alpha = 0.97) and a three-factor model including a Self factor (4 items, alpha = 0.90), a Social factor (11 items, alpha = 0.95) and an Environment factor (5 items, alpha = 0.90). CFA found the three-factor model had better model fit (P < 0.05). Both the one-factor and three-factor scores were negatively correlated with BMI and the Children’s Depression Inventory and positively correlated with generic quality of life, all at the P < 0.05 level. The 1-week test–retest intra-class correlation coefficients were 0.73 for Social, 0.71 for Self, 0.73 Environment and 0.77 for the one-factor model. The YQOL-W shows good reliability and validity for assessing weight-specific QOL in children and adolescents.
