Psychometric testing of the cross-culturally adapted Thai version of the Self-Care Self-Efficacy Scale version 3.0 in individuals with chronic illnesses

泰语版自我护理自我效能感量表在慢性病患者中的信效度检验

Objective:To assess the psychometric properties of the Thai version of the Self-Care Self-Efficacy Scale version 3.0(SCSES-v3.0)in individuals with chronic illnesses.Although originally developed and tested in a Western context,its applicability in Asian populations,including Thailand,remains inadequately explored.Methods:Psychometric tests were guided by COSMIN principles.This included the translation of the English version into Thai based on the ISPOR framework.Nine nursing experts evaluated the content validity.Data were obtained from a multicenter cross-sectional study conducted between July and November 2022.This study included individuals with chronic conditions from 16 primary care centers in Thailand.We tested the structural validity using exploratory factor analysis(EFA)and confirmatory factor analysis(CFA),and concurrent validity in relation to the Self-Care of Chronic Illness Inventory version 4.c(SC-CII-v4.c).We tested the scale’s reliability with McDonald’s u,Cronbach’s a,and the intraclass correlation coefficient(ICC).Results:The Thai SCSES-v3.0 demonstrated excellent content validity(k¼1.00).Thefinal analysis included a total of 385 participants.The EFA with thefirst split-half subsample(n¼193)extracted a twofactor structure.One reflected SCSES for maintenance and monitoring behaviors and another captured SCSES for management behaviors(item 6e10).CFA with the second split-half subsample(n¼192)and the overall sample(n¼385)supported the scale’s two-factor model with high factor loadings.Each dimension and the overall SCSES-v3.0 positively correlated with each scale and the overall SC-CII-v4.c.McDonald’s u and Cronbach’s a(both ranged 0.91e0.94)and ICC(ranged 0.95e0.96),indicated excellent internal reliability and test-retest reliability,respectively.Conclusions:The identification of a valid and reliable two-factor model for the Thai SCSES-v3.0 renders it a valuable tool for clinicians and investigators,facilitating the assessment of self-efficacy in self-care across diverse contexts.

目的评估泰语版自我护理效能感量表3.0(Self-Care Self-Efficacy Scale Version 3.0,SCSES-v3.0)的心理测量学特性。方法以COSMIN原则为指导,将英文量表版翻译成泰文版。9名护理专家对内容效度进行了评估。数据来自于2022年7月至11月进行的一项多中心横断面研究。研究对象包括泰国16所初级护理中心的慢性病患者。使用探索性因子分析和验证性因子分析测试结构效度,并结合慢性病自我护理量表4.c版测试并发效度。采用McDonald’sω、Cronbach’sα和组间相关系数检验量表的信度。结果泰语版SCSES-v3.0具有较好的内容效度(k=1.00)。最终分析了385例慢性病患者,对第一半样本(n=193)进行了探索性因子分析,提取出了双因子结构。一个因子反映了维护和监控行为,另一个因子则反映了管理行为(项目6~10)。第二半样本(n=192)和总体样本(n=385)的验证性因子分析支持量表的双因子模型,且因子载荷较高。McDonald’sω和Cronbach’sα(范围均为0.91~0.94)以及组内相关系数(范围为0.95~0.96)分别显示了良好的信度和效度。结论泰语版SCSES-v3.0具有有效可靠的双因素模型,可以成为临床护理人员和研究人员的重要工具,有助于在不同情况下评估慢性病患者自我保健的自我效能感。
