摘要
目的:评价自我护理能力实施量表(ESCA)中文版在精神分裂症患者中的信度和效度。方法:抽取150例精神分裂症患者进行ESCA初测,进行初步的项目分析;正式施测阶段抽取300例精神分裂症患者,7 d后对其中30例进行重测,计算克朗巴赫α系数、重测信度评价量表内部一致性;采用探索性因子分析方法考评量表结构效度;相关分析来评价量表的效标效度。结果:条目一总分相关法及决断值法对条目的区分度进行分析后,组成35个条目的新量表,经最大方差旋转法旋转后提取4个因子,4个因子累计解释的方差为42.38%;ESCA与日常生活能力评定量表、护士用住院病人观察量表相关系数分别为0.59,0.63;Cranach'sα系数为0.88,重测信度为0.65。结论:ESCA中文版具有较好的信度和效度,用于精神分裂症患者自我护理能力的研究需要反复修订。
Objective: To assess the reliability and validity of Chinese version in the exercise of self-care agency scale(ESCA) in patients with schizophrenia. Method:In pre-test phase, the scale was administered to 150 schizophrenia patients and the item analysis was conducted. In the formal test phase,300 schizophrenia patients ,30 of whom took it again 7 days later took the scale. Cronbach's α coefficient and test-retest reliability was calculated. Construct validity was assessed using exploratory factor analysis method, and the criterion validity was assessed using correlation analysis. Results:Thirty five items composed the scale in terms of item discrimination index,and four factors were extracted from 35 items by varimax rotation, accounting for 42.38% of the total variance. ESCA was significantly correlated with daily life ability scale and nurses'observation scale for inpatient evaluation (r = 0.59 and 0. 63,respectively). The Cronbach's α coefficient was 0. 88. The test-retest reliability was 0.65. Conelusion:ESCA Chinese version has good reliability and validity.
