Adapting and Testing the Self-Efficacy in Environmental Risk Reduction Instrument Among Spanish-Speaking Populations.

Abstract

The purpose of this study was to adapt and test the Self-Efficacy in Environmental Risk Reduction instrument in a Spanish-speaking population. Harkness' model of cross-cultural survey design was used to adapt the instrument. We sampled 95 adult, Spanish speakers from a federally qualified health clinic. Exploratory factor analysis with maximum likelihood estimation was used to analyze the factor structure. A 1-factor model provided the best fit to the data. The latent construct of the instrument is household environmental health self-efficacy. All items loaded higher than 0.610, indicating each item explains at least 36% variance in the latent construct. Cronbach's alpha indicates the scale has high internal consistency (α = .92). Respondents conceptualize self-efficacy in environmental risk reduction as practical solutions to minimize household risks.
