目的:评估5点尺度和11点尺度形式对量表信度的影响。方法:采用纵向调查,对同一人群进行先后两次测试亚健康状态评价量表,从条目相关分析、重测信度系数、分半信度系数和内部一致性信度系数等方面对不同尺度进行比较。结果:11点尺度各条目与所属领域的相关系数绝大多数高于5点尺度;将11点等级尺度转化为5点等级尺度进行相关系数比较,各条目、亚域、域间的相关系数也与未经转化的相关系数结果相当;分半信度系数和内部一致性信度系数的结果显示11点尺度比5点尺度的信度系数略高。结论:两种尺度形式各有特点,相对于11点尺度,5点尺度更容易被受试者理解,然而11点尺度在量表信度方面略占优势。
Purpose: To assess the effect of 5-point scale and 11-point scale on scale reliability. Methods: A longitudinal survey was conducted to test the sub-health status assessment scales for the same population twice. The different scales were performed from the item correlation analysis, test-retest reliability coefficient, half-reliability coefficient, and internal consistency reliability coefficient. Compare. RESULTS: Most of the 11-point scale correlation coefficients between the items and their fields were higher than the 5-point scale; the 11-level scale was converted to a 5-point scale to compare the correlation coefficients, and the correlation coefficients between the items, sub-domains, and domains were also The result is similar to the untransformed correlation coefficient; the results of the half-reliability coefficient and the internal consistency reliability coefficient show that the 11-point scale is slightly higher than the 5-point scale reliability coefficient. Conclusions: The two scales have their own characteristics. Compared with the 11-point scale, the 5-point scale is more easily understood by the subjects. However, the 11-point scale has a slight advantage in the reliability of the scale.
