Primary development and psychometric properties of PRECEDE model-based scales for brucellosis prevention among an iranian rural population

Abstract

Background: According to WHO, brucellosis is one of the 7 neglected zoonotic diseases and a major challenging issue for public health. Objectives: The aim of this study was to investigate the psychometric properties of the PRECEDE model-based scales for brucellosis prevention (PRECEDE-MSBP). Methods: In this cross-sectional study conducted in 2015, stratified random sampling was employed to recruit 420 rural residents in Ahar county, Iran. A comprehensive literature review was conducted to develop the initial draft of PRECEDE-MSBP. Face, content, and construct validity and reliability were determined. Results: Applying Exploratory Factor Analysis, the optimal solution including 37 items and 7 factors for Educational and Ecological diagnosis, 5 items and 2 factors for Environmental diagnosis, and 9 items and 3 factors for Behavioral diagnosis were emerged, which accounted for 60.43%, 56.51%, and 53.75% of the total variances, respectively. Appropriate validity, reliability, functionality, and simplicity were demonstrated for PRECEDE-MSBP. Conclusions: Researchers and health care providers interested in brucellosis prevention may apply the PRECEDE-MSBP inventory as a suitable instrument to provide the best information while conducting brucellosis prevention need assessments for their in-terventional efforts. However, further studies applying this instrument are needed in order to compare the different aspects of PRECEDE-MSBP in different communities.
