摘要

目的:利用验证性因子分析(CFA)和项目反应理论(IRT),对新近编制的社区传染病监测知识、态度和感知问卷(KAP-CBS-ID问卷)的心理测量学特性进行验证。方法:采用多阶段抽样的横断面研究方法,在马来西亚吉兰丹州招募了470名学校教师。自我管理的KAP-CBS-ID问卷包括3个领域:知识(31项)、态度(23项)和认知(21项)。采用双参数logistic (2-PL) IRT分析和CFA分析来验证知识部分。对于态度和感知部分,CFA使用四因素模型来评估模型拟合和结构效度。结果:知识部分的2-PL IRT分析导致14个项目因不充分的区分或难度参数而被淘汰。三因素CFA模型对知识的拟合指标较好(近似均方根误差[RMSEA], 0.028;比较拟合指数[CFI], 0.945;Tucker-Lewis指数[TLI], 0.941),无任何修改。态度部分需要重新规范,最终在4个因素中产生21个项目,具有可接受的拟合指数(标准化均方根残差[SRMR], 0.067;RMSEA 0.055;CFI, 0.937;0.927, TLI)。同样,感知部分在4个因素中被细化为17个项目,显示出良好的模型拟合(SRMR, 0.055;RMSEA 0.059;CFI, 0.962;0.954, TLI)。因子负荷范围为0.33 ~ 0.98,Raykov的rho信度估计范围为0.713 ~ 0.858。所有因素的因素确定度均超过80%。结论:KAP-CBS-ID是评估社区代表对社区传染病监测的知识、态度和看法的有效和可靠的工具。

A confirmatory analysis of the knowledge, attitudes, and perceptions questionnaire for community-based surveillance of infectious diseases: a cross-sectional study in Malaysia.

Objectives: This study aimed to validate the psychometric properties of the recently developed knowledge, attitudes, and perceptions questionnaire for community-based surveillance of infectious diseases (KAP-CBS-ID questionnaire), using confirmatory factor analysis (CFA) and item response theory (IRT).

Methods: A cross-sectional study using multistage sampling recruited 470 schoolteachers from Kelantan, Malaysia. The self-administered KAP-CBS-ID questionnaire consists of 3 domains: knowledge (31 items), attitudes (23 items), and perceptions (21-items). Two-parameter logistic (2-PL) IRT analysis and CFA were performed to validate the knowledge section. For attitudes and perceptions sections, CFA proceeded using a 4-factor model to evaluate both model fit and construct validity.

Results: 2-PL IRT analysis of the knowledge section resulted in elimination of 14 items due to inadequate discrimination or difficulty parameters. The 3-factor CFA model demonstrated good fit indices for knowledge (root mean square error of approximation [RMSEA], 0.028; comparative fit index [CFI], 0.945; Tucker-Lewis index [TLI], 0.941) without any modifications. The attitudes section required re-specification, ultimately yielding 21 items across 4 factors with acceptable fit indices (standardized root mean square residual [SRMR], 0.067; RMSEA, 0.055; CFI, 0.937; TLI, 0.927). Similarly, the perceptions section was refined to 17 items across 4 factors, showing good model fit (SRMR, 0.055; RMSEA, 0.059; CFI, 0.962; TLI, 0.954). Factor loadings ranged from 0.33 to 0.98, while Raykov's rho reliability estimates ranged from 0.713 to 0.858. Factor determinacy exceeded 80% for all factors.

Conclusion: The KAP-CBS-ID is a valid and reliable instrument for assessing community representatives' knowledge, attitudes, and perceptions regarding community-based surveillance of infectious diseases.
