The Theory of Planned Behaviour as Predictor of Exercise

Abstract

In a test of the predictive utility of the theory of planned behaviour alone and in conjunction with a number of additional variables, 114 participants completed questionnaires measuring predictor variables and, three weeks later, reported exercise. The results of the present study provide partial support for the theory. Past behaviour was the most predictive variable. Subjective norm was not a significant predictor of intention to exercise. Attitude towards exercise was also not a predictor of exercise intention. Self-monitoring acted as a moderator of the attitude-intention relationship. Perceived behavioural control was not a significant predictor of exercise behaviour, while exercise intentions were only weak predictors. The results also suggested that perceived behavioural control and perceived barriers are not equivalent, and should be treated as separate variables that contribute independently to the predictive ability of the model. The implications of the findings are discussed.

Some problems with social cognition models: A pragmatic and conceptual analysis.

“…For example, many studies using the TPB reported no role for subjective norms (eg. Bozionelos & Bennett, 1999;Jamner, Wolitski, Corby & Fishbein, 1998;De Wit, Stroebe, De Vroome, Sandfort & Van Griensen, 2000), some showed no predictive role for perceived behavioural control (eg. Flynn et al, 1997;Sutton, McVey & Glanz, 1999) and some showed no role for attitudes (eg.…”

Barriers Identification as Intervention to Engage Breast Cancer Survivors in Physical Activity

“…Based on Social cognitive theory (SCT)'s variables (Blaney et al, 2010;Rogers et al, 2011), we retained experienced fatigue, experienced side-effects (hair loss, scars), depression, and lack of information. Four cancer-related barriers items were then formulated, for instance: I am too tired to practice regular PA, which represents consequences of treatment that prevents exercising regularly (Bozionelos & Bennett, 1999). We decided to incorporate the guidelines on moderate-intensity PA only because if a barrier appears in moderate-intensity PA, it will remain present in vigorous-intensity PA and in order to avoid discouragement in a sample of inactive or sedentary women.…”

“…In this perspective, the most distinctive determinant related to adoption of health behavior is reported to be perceived barriers (Rogers et al, 2007(Rogers et al, , 2011Bozionelos & Bennett, 1999;Courneya & Friedenreich, 1999). Barriers generally reported in this vein by cancer survivors, like experienced nausea, fatigue, lack of energy, and pain, contribute to directly hinder in taking up PA as a routine (Blaney et al, 2010;Courneya & Friedenreich, 1999;Lewis & Lynch, 1993).…”

“…Barriers generally reported in this vein by cancer survivors, like experienced nausea, fatigue, lack of energy, and pain, contribute to directly hinder in taking up PA as a routine (Blaney et al, 2010;Courneya & Friedenreich, 1999;Lewis & Lynch, 1993). According to social cognitive researchers, perceived barriers are recognized as being predictive of decision to change (Arroyave et al, 2008;Walsh, 2006), and as explaining additional variance in both readiness to PA and actual performance of the PA behavior (Rogers et al, 2011;Bozionelos & Bennett, 1999). TTM constructs have previously been applied to the study of PA with cancer survivors but few studies have examined the contribution of cancer-related barriers in decision to change (Bandura, 1997;Benisovich, Rossi, Norman, & Nigg, 1998;McAuley & Mihalko, 1998).…”

“…In other words, because adoption of PA is a difficult challenge for healthy adults and is likely to be even more difficult after receiving a cancer diagnosis, and because TTM's main goal is to explain how health behavior change occurs, a focus is needed on the contribution of cancer-related barriers in order to better respond to TTM's fundamental principle of stage transition in cancer population. Hence, the aim of our two studies was to determine the contribution of cancer relatedbarriers to the components of decision-making in Transtheoretical Model (TTM) (Bozionelos & Bennett, 1999;Friedenreich & Courneya, 1996). The importance of these cancer-related determinants in explaining PA in breast cancer survivors remains unclear for two main reasons: first, barriers often are confounded with cons and second, the decision-making to engage in regular PA seems dependent of barriers (Rogers et al, 2011).…”
