In Hong Kong, the measurement of perceived health status in patients with low back pain (LBP) can be facilitated by the availability of a health profile specifically designed for the Chinese culture. This prospective observational study investigated the psychometric properties of the generic Current Perceived Health 42 (CPH42) Profile in four separate samples (totalling 473) of Chinese patients with LBP in Hong Kong. The patients completed the CPH42 Profile and the Roland LBP Disability Scale at various points in the course of physiotherapy. Their pain intensity was measured using the 11-point pain numerical rating scale (NRS). The test-retest reliability and internal consistency of the CPH42 Profile demonstrated high intra-class correlation coefficient of 0.92 and Cronbach's alpha of 0.90. Validity was confirmed by a moderate correlation with the Chinese adaptations of the Roland LBP Disability Scale and the NRS at the commencement of physiotherapy (Spearman's correlation coefficients were 0.48 and 0.42, respectively). The responsiveness, measured from the commencement of physiotherapy to weeks 3 and 6 (standard response means of 0.33 and 0.58, respectively), were commensurate with the respective changes in pain intensity. The psychometric properties of the CPH42 Profile suggest its suitability for use as an outcome instrument in future efficacy studies on LBP intervention.
在香港，专门为中国文化设计的健康状况档案有助于对腰痛（LBP）患者的健康状况感知进行测量。这项前瞻性观察研究在香港的四个独立样本（共473名）中国腰痛患者中调查了通用的当前健康感知42项（CPH42）档案的心理测量特性。患者在物理治疗过程中的不同时间点完成了CPH42档案和罗兰腰痛残疾量表。使用11点疼痛数字评分量表（NRS）测量他们的疼痛强度。CPH42档案的重测信度和内部一致性显示组内相关系数高达0.92，克朗巴哈系数为0.90。在物理治疗开始时，与罗兰腰痛残疾量表的中文版和NRS的中度相关性证实了其效度（斯皮尔曼相关系数分别为0.48和0.42）。从物理治疗开始到第3周和第6周测量的反应度（标准反应均值分别为0.33和0.58）与疼痛强度的相应变化相当。CPH42档案的心理测量特性表明它适合作为未来腰痛干预疗效研究的结果工具。
