Construct validity and reliability of the Spanish version of Spirituality Index of Well-Being (SIWB) in Colombian population with chronic lung disease

Abstract

Introduction: Chronic obstructive pulmonary disease (COPD) is a public health problem that is increasing in Colombia, with high social and economic costs, without instruments to measure their conditions directly. Objective: To study the construct validity and reliability of the Spanish version of the questionnaire Spirituality Index of Well-Being (SIWB) in a Colombian sample of patients diagnosed with chronic lung disease. Methodology: Cross-sectional study, descriptive scope and instrument type, where applied the questionnaire to 71 adult patients diagnosed with chronic obstructive pulmonary disease in Bogota. Factor analyzes were performed by extraction method of principal components with Varimax rotation and analysis of consistency by Cronbach’s alpha for the overall scale and each factor obtained inter-item correlations and statistical full-element. Results: Factor analysis indicates two factors: self-efficacy (38.884% of explained variance) and life patterns (37.557% of explained variance), factors explaining 76,440% of the total cumulative variance and consistent with the theoretical proposal of the scales, as well as a general Cronbach, 943 and positive correlations between all reagents. Conclusions: The scale shows high reliability, appropriate internal consistency between the reactants, concordance between elements-all corrected, and agreement on the factorial structure with the original version, suggesting adequate construct validity of the test, with appropriate reliability and consistency Colombian population of chronically ill.
