Meta-Analysis of the Reasoned Action Approach (RAA) to Understanding Health Behaviors

Abstract

BackgroundReasoned action approach (RAA) includes subcomponents of attitude (experiential/instrumental), perceived norm (injunctive/descriptive), and perceived behavioral control (capacity/autonomy) to predict intention and behavior.PurposeTo provide a meta-analysis of the RAA for health behaviors focusing on comparing the pairs of RAA subcomponents and differences between health protection and health-risk behaviors.MethodsThe present research reports a meta-analysis of correlational tests of RAA subcomponents, examination of moderators, and combined effects of subcomponents on intention and behavior. Regressions were used to predict intention and behavior based on data from studies measuring all variables.ResultsCapacity and experiential attitude had large, and other constructs had small-medium-sized correlations with intention; all constructs except autonomy were significant independent predictors of intention in regressions. Intention, capacity, and experiential attitude had medium-large, and other constructs had small-medium-sized correlations with behavior; intention, capacity, experiential attitude, and descriptive norm were significant independent predictors of behavior in regressions.ConclusionsThe RAA subcomponents have utility in predicting and understanding health behaviors.

Broadening the evidence for the Theory of Planned Behavior: predicting heavy episodic drinking in Argentinean female and male youth

“…Intention has been shown to be one of the most consistent predictors of behavior in general and HED in particular (Armitage & Conner, 2001;Hagger, 2015;McEachan et al 2016). We found that perceived behavioral control predicted behavior among women, contrary to other studies that found it as predictor for both men and women (Barrat & Cooke, 2016) suggesting also their positive influence on 165 behavior.…”

“…The perception of behavioral control can also act directly on the behavior. This model has been used successfully in predicting a variety of behaviors, including alcohol consumption (Ajzen, 2002;Armitage & Conner, 2001, McEachan, Taylor, Harrison, Lawton, Gardner, & Conner, 2016. The use of TPB in relation to HED is recent in college students populations, explaining to a high degree HED intention, and a good fit in the prediction of HED behavior (Collins, Witkiewitz, & Larimer, 2011;Cooke, Sniehotta, & Schüz, 2007;Dempster, Marley, & Newell, 2004;Elliott & Ainsworth, 2012;Jamison & Myers, 2008;Johnston & White, 2003;Norman, 2011;Norman & Conner, 2006;Norman, Armitage, & Quigley, 2007;Todd & Mullan, 2011;).…”

Matching Local Food Messages to Consumer Motivators: An Experiment Comparing the Effects of Differently Framed Messages

“…The theory of reasoned action and its extension theory, theory of planned behavior, have a been used extensively by researchers to explain or predict many types of behaviors, including health and food decisions, and their respective behavioral antecedents (McEachan et al, 2016;McEachan, Connor, Taylor, & Lawton, 2011). The theory of planned behavior (TPB) accounts for attitudes toward the behavior, subjective norms, and perceived behavioral control as antecedents to behavioral intent and overt behavior.…”

Consequences of Borrowing Money from Lending Institutions in Relation to Job Performance

“…He believed that people possess a set of motivation systems unrelated to rewards or unconscious desires. Maslow (1943) stated that people are motivated to achieve certain needs and that some needs take precedence over others. Our most basic need is for physical survival, and this will be the first thing that motivates our behavior.…”
