本文采用主成分分析法对环境风险降低工具中的家庭风险感知和自我效能感进行了心理测试。可用于测试与环境卫生行为有关的家庭风险感知和自我效能的工具有限。制定了家庭风险感知工具，以衡量个人对家庭环境健康风险的感知。自我效能在环境风险降低工具的设计，以衡量照顾者的信心采取措施，以减少家庭风险。在2006年至2009年期间，收集了235名参加健康住房干预随机临床试验的护理人员的基线数据。主成分分析用于从对每个仪器的测量响应中确定主成分。研究了组件，并将其与用于设计原始仪器的结构进行了比较。五组分结构显示了最简单的解决方案，并解释了65%的方差在家庭风险感知分析。Cronbach的alpha值表明，五个已识别成分中的四个具有令人满意的内部一致性。风险感知根据特定风险的可用感官输入而变化。在环境风险降低分析中，一个四成分结构解释了64%的自我效能差异。Cronbach的alpha值令人满意。映射到面向操作的流程中的步骤的项与特定于代理的操作的项。两项分析的结果都表明，人们对环境烟草烟雾的认识不同于对其他家庭风险的认识。以前，这两种工具都依赖于项目信度和内容效度测试。本研究为进一步的仪器修正和理论检验提供了基础。
This paper is a report of psychometric testing of the Household Risk Perception and Self-Efficacy in Environmental Risk Reduction Instruments using principle components analysis. There are limited instruments available to test household risk perception and self-efficacy related to environmental health behaviors. The Household Risk Perception Instrument was developed to measure personal perceptions of household environmental health risks. The Self-Efficacy in Environmental Risk Reduction Instrument was designed to measure caregivers’ confidence in taking steps to reduce household risks. Baseline data from 235 caregivers enrolled in a randomized clinical trial testing a healthy housing intervention were collected between 2006 and 2009. Principal components analysis was used to determine principal components from measured responses to each instrument. Components were explored and compared to constructs used to design the original instruments. A five component structure showed the simplest solution and explained 65% of variance in the Household Risk Perception analysis. Cronbach’s alpha values indicated satisfactory internal consistency for four of five identified components. Risk perception varied according to available sensory input of the specific risk. A four component structure explained 64% of the variance in the Self-Efficacy in Environmental Risk Reduction analysis. Cronbach’s alpha values were satisfactory. Items mapped to steps in an action-oriented process versus agent-specific actions. Results from both analyses suggest that Environmental Tobacco Smoke is perceived differently than other household risks. Previously, both instruments relied on item reliability and content validity testing. This study provides a basis for further instrument revision and theoretical testing.
