Evaluation of the reliability and validity of the modified Morisky scale for patient’s compliance with moxibustion

Abstract

Objective

A questionnaire for the compliance with moxibustion was designed based on the 4-item Morisky scale, and the reliability and validity of the questionnaire was investigated.

Methods

A modified Morisky scale was designed based on the 4-item Morisky scale for the compliance with moxibustion, and 146 patients having received moxibustion for over 2 weeks were investigated using this scale to evaluate their compliance with moxibustion; the internal equity and the construct validity of the scale were statistically analyzed.

Results

The analysis of reliability showed that in item of internal consistency, the Cronbach’s α was 0.72 and the split-half coefficient was 0.71, the correlation coefficients between the 4 component scores and the total score ranged 0.67-0.80, and the between-component correlation coefficients ranged 0.24-0.56; the exploratory factor analysis (EFA) totally extracted 1 common factor, and the explicable variation was 55.02%, and the loads of the 4 items were respectively 0.82, 0.81, 0.74 and 0.58.

Conclusion

The reliability and validity of the modified Morisky scale for the compliance with moxibustion are acceptable, while several items need further modification and improvement in the expression and content.

摘要

目的

基于Morisky 依从性量表4个条目设计艾灸依从性调查问卷, 探讨该问卷的信度和效度。

方法

根 据Morisky 依从性量表4个条目设计用于艾灸依从性评价的修改版Morisky 问卷, 并对146例接受艾灸治疗超过2 星期的患者使用该问卷进行调查, 评价艾灸治疗依从性; 统计分析该量表的内部一致性及其结构效度。

结果

信 度分析显示, 修改版Morisky 问卷的内部一致性Cronbach’s α 系数为0.72, 折半系数为0.71, 4个条目与量表总分之 间的相关系数为0.67~0.80, 4 个条目之间的相关系数为0.24~0.56, 探索性因子分析共提取1个公共因子, 可解 释的总变异量为55.02%, 4条目的载荷值分别为0.82、0.81、0.74和0.58。

结论

修改版Morisky 问卷调查艾灸依从 性的信度和效度尚可, 但部分条目在语言表述和内容上仍需进一步修订和完善。
