To examine the extent to which the theory of planned behavior (TPB) predicts academic clinicians’ intent to treat pediatric obesity.
A multi-disciplinary panel iteratively devised a Likert scale survey based on the constructs of the TPB applied to a set of pediatric obesity themes. A cross-sectional electronic survey was then administered to academic clinicians at tertiary care centers across Canada from January to April 2012. Descriptive statistics were used to summarize demographic and item agreement data. A hierarchical linear regression analysis controlling for demographic variables was conducted to examine the extent to which the TPB subscales predicted intent to treat pediatric obesity.
A total of 198 physicians, surgeons, and allied health professionals across Canada (British Columbia, Alberta, Manitoba, Saskatchewan, Nova Scotia, Ontario and Quebec) completed the survey. On step 1, demographic factors accounted for 7.4% of the variance in intent scores. Together in step 2, demographic variables and TPB subscales predicted 56.9% of the variance in a measure of the intent to treat pediatric obesity. Perceived behavioral control, that is, confidence in one’s ability to manage pediatric obesity, and subjective norms, congruent with one’s context of practice, were the most significant predictors of the intent to treat pediatric obesity. Attitudes and barriers did not predict the intent to treat pediatric obesity in this context.
Enhancing self-confidence in the ability to treat pediatric obesity and the existence of supportive treatment environments are important to increase clinicians’ intent to treat pediatric obesity.
Core tip: Clinicians play an integral role in diagnosing and managing childhood obesity. This study examined how the theory of planned behavior (TPB) predicted academic clinicians’ intent to treat pediatric obesity. Demographic variables and TPB subscales predicted 56.9% of the variance in intent scores amongst health professionals to treat pediatric obesity. One’s practice context (subjective norms) and confidence in one’s ability to manage pediatric obesity (perceived behavioral control) were the most significant predictors of intent. Attitudes and barriers did not predict intent. The TPB can be applied to strengthen clinical training programs targeted towards management of obesity in children.
