The authors report the results of 3 studies that were conducted to evaluate the psychometric properties of the Physical Health Questionnaire (PHQ), a brief self-report scale of somatic symptoms. In Study 1, exploratory factor analysis results revealed 4 empirically distinct dimensions of somatic symptoms: gastrointestinal problems, headaches, sleep disturbances, and respiratory illness. In Study 2, this structure was replicated using confirmatory factor analysis, and correlations of the PHQ dimensions with measures of negative affect, psychological health, and job performance provided further validity evidence. In Study 3, a minor revision to the wording of several items helped to address the limitations of one of the PHQ subscales. Together, these results provide evidence of the construct validity of the PHQ.
作者报告了3项研究的结果，这些研究旨在评估身体健康问卷（PHQ）的心理测量特性，该问卷是一种简短的自我报告躯体症状量表。在研究1中，探索性因素分析结果揭示了躯体症状的4个经验上不同的维度：胃肠道问题、头痛、睡眠障碍和呼吸道疾病。在研究2中，使用验证性因素分析复制了这一结构，并且PHQ维度与负面影响、心理健康和工作绩效测量指标之间的相关性提供了进一步的效度证据。在研究3中，对几个条目的措辞进行了微小修订，有助于解决PHQ其中一个子量表的局限性。总之，这些结果为PHQ的结构效度提供了证据。
