中文版出院后应对能力量表的可靠性和结构效度

The Reliability and Structural Validity of the Chinese Version of the Coping Ability Scale after Discharge

摘要: 目的：将出院后应对能力量表(PDCDS)根据文化差异进行调适汉化为中文版，并评价其信度和效度。方法：首先，对原量表进行翻译、回译和文化调适，确定中文版出院后应对能力量表。其次，采用方便抽样，使用中文版出院后应对能力量表对武汉市三级医院甲等两所和三级医院乙等一所于2020年9月~2020年11月出院的93例出院患者进行电话随访问卷调查，评定该工具的信效度。结果：汉化后PDCDS量表共包括7个条目，量表各条目CVI值为0.94~1.00，总量表的CVI值0.94，得到的评价者间一致性水平值为0.94；通过探索性因子分析共提取2个公因子，累积方差贡献率为76.584%；验证性因子分析因子负荷量在0.635~0.880之间，平均方差抽取量(AVE)分别为0.599和0.680，组合信度(CR)为0.871和0.854；整个量表的Cronbach’a系数为0.892，各维度的Cronbach’a系数分别为0.850、0.709；整个量表的Guttman折半系数为0.869，各维度的Guttman折半系数分别为0.852、0.709；总量表的重测信度为0.951，每个条目重测信度为0.902~0.972。结论：汉化后的PDCDS量表具有良好的信效度，适用于患者出院后对所面临困难应对能力的一种测评。

Abstract: Objective: Coping Difficulties after Hospitalization (PDCDS) was adapted to Chinese version according to cultural differences, and its reliability and validity were evaluated. Method: First of all, the original scale is translated, back-translated and culturally adjusted, and the Chinese version of the coping ability scale after discharge from the hospital is determined. Second, convenience sampling was adopted and the Chinese version of Coping Difficulties after Hospitalization was used to conduct telephone follow-up of 93 discharged patients who were discharged from September 2020 to November 2020 in two third-level hospitals in Wuhan City questionnaire survey to evaluate the reliability and validity of the tool. Results: The revised Chinese version of the PDCDS scale includes 7 items. The CVI value of each item of the scale is 0.94~1.00, and the CVI value of the total scale is 0.94. The inter-rater consistency level value obtained is 0.94; it is extracted by exploratory factor analysis. 2 common factors, the cumulative variance contribution rate is 76.584%. The confirmatory factor analysis factor load is between 0.635~0.880, the average variance extraction (AVE) is 0.599 and 0.680, and the combined reliability (CR) is 0.871 and 0.854; the Cronbach’a coefficient of the entire scale is 0.892, and the Cronbach’a coefficients of each dimension are 0.850 and 0.709 respectively; the Guttman’s half-coefficient of the entire scale is 0.869. The Guttman’s halving coefficients of the dimensions are 0.852 and 0.709, respectively; the test-retest reliability of the total scale is 0.951, and the test-retest reliability of each item is 0.902~0.972. Conclusion: The Chinese version of the PDCDS scale has good reliability and validity and can be used to evaluate the ability of Chinese patients to cope with difficulties after they are discharged from the hospital.
