To evaluate the construct validity of the standard Chinese Short Form (SF)-12v2 in adolescents.
Data collected from the Hong Kong Student Obesity Surveillance project conducted in 2006-2007 were used. The standard Chinese SF-12v2 was first evaluated against clinical criteria previously used for the evaluation of SF-12 or SF-36. The data were then randomly split into training and validation halves for exploratory and confirmatory factor analyses, respectively.
A total of 31,357 adolescents with mean age of 14.8 years (standard deviation=1.9; range=11.0-18.9) were included. The standard Chinese SF-12v2 effectively distinguished groups differing in doctor-diagnosed health problems, self-reported illnesses in the past 30 days, gender, perceived health in the past 3 months, and health compared with that 12 months back. The mental health scale had low internal consistency (Cronbach's alpha=0.34). The exploratory factor analysis was influenced by method effects, but confirmatory factor analysis confirmed the hypothesized latent structure and the one-factor structure of the SF-12v2, providing fit indices within acceptable limits.
The two components and a single general health component of the standard Chinese SF-12v2 are appropriate health indicators for Chinese adolescents.
评估标准中文简式健康量表 12 版（SF-12v2）在青少年中的结构效度。
使用 2006-2007 年香港学生肥胖监测项目收集的数据。首先，根据之前用于评估 SF-12 或 SF-36 的临床标准，对标准中文 SF-12v2 进行评估。然后，将数据随机分为训练和验证两半部分，分别进行探索性和验证性因子分析。
共纳入 31357 名年龄为 14.8 岁（标准差=1.9；范围为 11.0-18.9）的青少年。标准中文 SF-12v2 能够有效区分有医生诊断健康问题、过去 30 天内自我报告疾病、性别、过去 3 个月内自我感知健康状况以及过去 12 个月内健康状况的人群。心理健康量表的内部一致性较低（克朗巴赫α系数=0.34）。探索性因子分析受到方法效应的影响，但验证性因子分析证实了 SF-12v2 的假设潜在结构和单因素结构，提供了可接受范围内的拟合指数。
标准中文 SF-12v2 的两个分量和一个总体健康分量是适合中国青少年的健康指标。
