In homeopathy the choice of a medicine is based on the total 'picture' presented by the patient. This picture includes 'constitutional type' which comprises personality, and general physical features. The Constitutional Type Questionnaire (CTQ) is designed to systematically assess constitutional types. This study examines the reliability and validity of the CTQ. Four hundred and seventy-two outpatients attending clinics at the Royal London Homoeopathic Hospital completed the CTQ, a 152-item scale rating features traditionally considered typical of 19 constitutional homeopathic medicine 'pictures' on 5-point frequency or severity scales. A subsample was retested after 1 week to measure the test-retest reliability. Another subsample was prescribed a medicine by a homeopathic doctor. Prescriptions were compared with the CTQ, to assess the content validity of the scale. The construct validity was measured by Grade of Membership (GOM) analysis. The scale demonstrated good test-retest reliability (r=0.73), internal consistency (r=0.95). The correlation between CTQ results and the medicine prescribed by the homeopathic doctor was 75.8%. The GOM analyses are reported by Davidson et al elsewhere in this issue of the journal. Although the CTQ could be improved, the scale displays good reliability and validity.
在顺势疗法中，药物的选择基于患者呈现的整体“情况”。这种情况包括“体质类型”，它涵盖了个性和一般身体特征。体质类型问卷（CTQ）旨在系统地评估体质类型。本研究考察了CTQ的信度和效度。472名在皇家伦敦顺势疗法医院诊所就诊的门诊患者完成了CTQ，这是一个152项的量表，根据5分制的频率或严重程度量表对传统上被认为是19种顺势疗法药物“情况”典型特征进行评分。一个子样本在1周后重新测试以测量重测信度。另一个子样本由顺势疗法医生开了一种药。将处方与CTQ进行比较，以评估该量表的内容效度。结构效度通过隶属度（GOM）分析来测量。该量表显示出良好的重测信度（r = 0.73）、内部一致性（r = 0.95）。CTQ结果与顺势疗法医生所开药物之间的相关性为75.8%。GOM分析由戴维森等人在本期杂志的其他地方报道。尽管CTQ可以改进，但该量表显示出良好的信度和效度。
