摘要 目的:探讨广泛性焦虑量表(GAD-7)在颈椎病患者焦虑情绪评估的信度和效度。方法:应用GAD-7及焦虑自评量表(SAS)对100例颈椎病患者进行筛查,同时进行美国《精神障碍诊断与统计手册》第4版(DSM-Ⅳ)临床定式访谈(SCID)评定。随机抽取30例患者在GAD-7测定1周后再次进行GAD-7评定。结果:GAD-7 Cronbach'sα系数为0.965;各条目与量表总分的相关系数为0.882~0.938,各条目间相关系数为0.718~0.887,相关有统计学意义(P均<0.01)。1周后重测信度为0.952。GAD-7总分与SAS总分的Pearson相关系数为0.884(P<0.01)。探索性因子分析显示该量表为1个因子结构,解释方差82.90%。以GAD-7≥10分为划界分,GAD-7灵敏度为94.23%,特异度为93.75%;与SCID评定的一致性Kappa值为0.880(u=18.345,P<0.01)。结论:GAD-7应用于颈椎病患者焦虑情绪评估具有良好的信度和效度。 Objective: To explore the reliability and validity of generalized anxiety disorder scale-7(GAD-7) in patients with cervical spondylosis. Method: A total of 100 patients with cervical spondylosis were assessed using GAD-7 and self-rating anxietyscale(SAS). The structured clinical interview for diagnostic and statistical manual of mental disorders(SCID) was used to diagnose generalized anxiety disorder. Thirty cases among them were random sampled and assessed again by GAD-7 after 1 week. Results: Cronbach's α coefficient of GAD-7 was 0. 965. The correlation coefficients of the seven items with the total scale ranged from 0. 882 to 0. 938,The mean inter-item correlation coefficients ranged from 0. 718 to 0. 887,the correlation coefficients were statistically significant(P〈 0. 01). The test-retest reliability value of GAD-7 was 0. 952. The correlation coefficient between total score of GAD-7 and SAS was 0. 884(P 〈0. 01). The exploratory factor analysis result indicated that the scale showed one dimension,which explained 82. 90% of total variance. With a cut point of10,the sensitivity and specificity for GAD-7 was 94. 23% and 93. 75%,respectively. The Kappa value between GAD-7 and SCID was 0. 880(u = 18. 345,P 〈0. 01). Conclusion: GAD-7 has good reliability and validity in cervical spondylosis patients.
