Predicting short-term weight loss using four leading health behavior change theories

Abstract

Background:This study was conceived to analyze how exercise and weight management psychosocial variables, derived from several health behavior change theories, predict weight change in a short-term intervention.

The Effect of Education on Reducing Fast Food Consumption in Obese Iranian Female Adolescents: An Application of the Transtheoretical Model and the Theory of Planned Behaviour

“…The increase in self-efficacy among the 5 stages has been confirmed by Jiang G and Palmira's studies (15,18,19). In Palmeira AL study, self-efficacy accounted for a large share of the predictive power.…”

Application of the Theory of Planned Behaviour to weight control in an overweight cohort. Results from a pan-European dietary intervention trial (DiOGenes)

“…These two studies explained 7.9% and 19.4% of the variance in weight loss using the TPB. A study by Palmeira et al (2007) explained 14.8% of the variance in weight management behaviours using intentions, attitude, subjective norm and PBC (attitude and PBC were significant in the model) (Palmeira et al, 2007). However, it is important to note that the current study investigated weight gain prevention, rather than weight loss.…”

“…The TPB was first developed by Ajzen in the 1980s (Schifter & Ajzen 1985, Ajzen, 1991 and is one of the most widely used theoretical frameworks for explaining health behaviours (Godin & Kok, 1996). The TPB has been applied to a range of diet and weight related behaviours including fat intake (de Bruijn, Kroeze, Oenema, & Brug, 2008;Paisley & Sparks, 1998) and fruit and vegetable consumption (Bogers, Brug, Van Assema, & Dagnelie, 2004;Kellar & Abraham, 2005;Lien, Lytle, & Komro, 2002;Perugini & Bagozzi, 2004); healthy eating behaviour (Conner, Norman, & Bell, 2002;Povey, Conner, Sparks, James, & Shepherd, 2000c) and weight control (Netemeyer, Burton, & Johnston, 1991;Palmeira et al, 2007;Schifter & Ajzen, 1985). The TPB suggests that the best predictor of actual behaviour is a person's intention to perform the behaviour.…”

The influence of physical activity on appetite control: an experimental system to understand the relationship between exercise-induced energy expenditure and energy intake

“…An extended time period means that acute effects can be compared with effects emerging over the longer term. This longitudinal approach also allows the investigation of mediators and modulators on the outcome variables; that is, those factors that predict changes and those which are associated with the process of change (57)(58)(59) . It is also important that research designed to have a high degree of relevance should reflect certain features of the obesogenic environment, and especially the high-risk factors.…”
