Factor structure and internal reliability of an exercise health belief model scale in a Mexican population

Abstract

BackgroundMexico is one of the countries with the highest rates of overweight and obesity around the world, with 68.8% of men and 73% of women reporting both. This is a public health problem since there are several health related consequences of not exercising, like having cardiovascular diseases or some types of cancers. All of these problems can be prevented by promoting exercise, so it is important to evaluate models of health behaviors to achieve this goal. Among several models the Health Belief Model is one of the most studied models to promote health related behaviors. This study validates the first exercise scale based on the Health Belief Model (HBM) in Mexicans with the objective of studying and analyzing this model in Mexico.MethodsItems for the scale called the Exercise Health Belief Model Scale (EHBMS) were developed by a health research team, then the items were applied to a sample of 746 participants, male and female, from five cities in Mexico. The factor structure of the items was analyzed with an exploratory factor analysis and the internal reliability with Cronbach’s alpha.ResultsThe exploratory factor analysis reported the expected factor structure based in the HBM. The KMO index (0.92) and the Barlett’s sphericity test (p < 0.01) indicated an adequate and normally distributed sample. Items had adequate factor loadings, ranging from 0.31 to 0.92, and the internal consistencies of the factors were also acceptable, with alpha values ranging from 0.67 to 0.91.ConclusionsThe EHBMS is a validated scale that can be used to measure exercise based on the HBM in Mexican populations.

Can the Health Belief Model and moral responsibility explain influenza vaccination uptake among nurses?

“…The HBM has identified six factors that are associated with the performance of a health-related behaviour: (a) perceived susceptibility of the health threat; (b) perceived severity of the health threat; (c) perceived benefits associated with the behaviour; (d) perceived barriers associated with the behaviour; (e) cues to action; and (f) self-efficacy (Janz & Becker, 1984;Rutter & Quine, 2002). The HBM has been used extensively to explain various health behaviours including smoking (Mohammadi et al, 2017), dietary behaviours (Khoramabadi et al, 2016), exercise (Soleymanian, Niknami, Hajizadeh, Shojaeizadeh, & Montazeri, 2014;Villar et al, 2017), HIV risky behaviour (Zhao et al, 2012) and vaccine uptake (Vermandere et al, 2016). To our knowledge, no study has investigated factors associated with the uptake of influenza vaccination among nurses in Hong Kong using the HBM.…”

Use pattern and predictors of use of highly caffeinated energy drinks among South Korean adolescents: a study using the Health Belief Model

“…The Health Belief Model (HBM) 24 is a commonly employed theoretical model used to explain the relationship between individuals’ beliefs and their behaviours in individual areas of health. 25 In order to assist decisions concerning the correct actions to adopt to address certain issues, the model advocates considering ‘perceived health threat’, ‘likelihood of action’ and ‘cue to action’. 26 Specifically, ‘perceived health threat’ relates to perceived susceptibility to a particular health problem and the perceived severity of that health problem; ‘likelihood of action’ is defined as when an individual considers the perceived benefits and barriers associated with certain actions; and ‘cue to action’ is defined as exposure to commercial advertisements and recommendations from acquaintances that encourage the user to make a behavioural change.…”

Creencias en obesidad y cirugía bariátrica: análisis de contenido para diseñar una escala

“…Este estudio se acogió a las normas éticas internacionales (Asociación Médica Mundial, 2008). Fue aprobado por dos comités de ética de investigación debido a que es una exigencia de la legislación ecuatoriana, país donde se recogieron los datos (Corrales, 2010;Vance, 2014). Por otra parte, el trabajo constituye parte de una tesis de investigación doctoral (Pontificia Universidad Católica del Perú (PUCP), 2011).…”
