The aim of the study was to evaluate the psychometric properties of the German translation of the Child Health Questionnaire (CHQ). Parents of two clinical samples were asked to rate the quality of life of their children using the German version of the CHQ. Item internal consistency (item-scale correlation) and internal consistency of scales were tested; quartiles and factor analysis were conducted. The results of the German clinical samples were compared with US clinical samples (t-test). The two clinical German sub-groups were compared using multivariate analysis (MANOVA). The psychometric testing of the CHQ showed good results. Internal consistency of the hypothesized scales were all higher than 0.70. The results of the factor analysis confirmed the results of the US norm sample: As expected, the subscales loaded on two factors explaining 57.4% of the total variance. The group comparison supported the discriminative properties of the CHQ. Preliminary psychometric findings support use of the German version of the CHQ. The next step will be the testing of healthy German samples and development of norm scores.
本研究的目的是评估儿童健康问卷（CHQ）德文版的心理测量特性。要求两个临床样本的家长使用CHQ德文版对其子女的生活质量进行评分。测试了项目内部一致性（项目-量表相关性）和量表的内部一致性；进行了四分位数和因子分析。将德国临床样本的结果与美国临床样本进行比较（t检验）。使用多变量分析（MANOVA）对两个德国临床亚组进行比较。CHQ的心理测量测试结果良好。假设量表的内部一致性均高于0.70。因子分析结果证实了美国常模样本的结果：正如预期的那样，子量表加载在两个因子上，解释了总方差的57.4%。组间比较支持了CHQ的区分特性。初步心理测量结果支持使用CHQ德文版。下一步将是对德国健康样本进行测试并制定常模分数。
