SF-36在慢性软组织疼痛患者中的信度和效度初步评价

The reliability and validity of the SF-36 health survey for patients with chronic soft tissue pain

目的 探讨中文版36条健康状况简明调查问卷(SF-36)在慢性软组织疼痛患者健康生存质量评价中的信度和效度.方法 采用中文版SF-36和医院结局疼痛用量表(MOSPM),同时对210例慢性软组织疼痛患者进行问卷调查,以后者为效度标准,其中有57例(27.1%)患者进行了二次测评.收集资料输入SPSS软件包,采用Spearman相关分析,进行内部一致性、复测信度和效标效度的评价.结果 SF-36量表具有良好的内部一致性和重测信度,8个维度的Cronbach's α系数均>0.7,重测信度的组内相关系数除SF为0.336(P<0.05)外,其他7个维度均在0.44～0.66之间(P<0.01);在效度评价中,SF-36的8个维度与MOSPM的大部分条目及总分均显著相关,相关系数在-0.145～-0.630之间(P<0.05,P<0.01).结论 SF-36在慢性软组织疼痛患者人群健康相关生存质量评价中应用,具有较好的信度和效度.

Objective To explore the reliability and validity of the Chinese version of the 36-item Short Form Health Survey (SF-36) for evaluating the health-related quality of life of patients with chronic soft tissue pain, (CSTP). Methods Two hundred and ten CSTP patients were rated with the SF-36 and the Medical Outcomes Study Pain Measurement (MOSPM) instrument and retested 2 weeks later. The internal consistency, test-retest relia-bility and parallel validity of the SF-36 were analyzed. Results The SF-36 showed good internal consistency and test-retest reliability. Most repeated reliability internal correlation coefficients were between 0.44 and O. 66 (P≤0.01) except that of the SF sub-scale of the SF-36, which was O. 336 (P≤0.05). All the internal consistency Cronbach's a coefficients were >0.70. In the assessment of validity, there was significant correlation among all eight sub-scales of the SF-36, and between items 4-11 and total MOSPM scores. The correlation coefficients were between -0.145 and 0. 635 (P≤0.05 or P≤0.01), except between GH of the SF-36 and item 4 of the M OSPM (pain in-fluence on walking) and between MH and item 10 (pain influence days). Conclusion The Chinese version of the SF-36 has good reliability and validity in assessing the health related quality of life of CSTP patients.
