The purpose of this research was to identify the extent to which consumers would accept the recommendation of taking weight-loss medications, based on the source of the recommendation. Research shows that the source of knowledge for information plays a significant role in health-related decision-making of consumers (Pornpitakpan, 2004). In comparison to traditional weight-loss methods such as diet and exercise, research studies report bias' against the use of prescription (Rx) and over-the counter (OTC) weight-loss medications among both physicians (MD) and certified personal trainers (CPT) (Ashworth, 2002; Holcomb, 2012). Given the current obesity epidemic in the United States (CDC, 2013), the research model examined two different sources of knowledge for weight-loss medications (MD versus CPT). The objective of the study was to examine the influence each source (MD and CPT) had on consumer-based decision-making, and the extent to which each source altered consumers' intention to try a weight-loss medication. The internet-based research company, Research Now®, administered the on-line survey instrument to qualifying participants (N=168), and collected data for the treatment interventions. Subjects who qualified for the treatment completed a validated questionnaire that collected data on attitudes about physicians, certified personal trainers, types of weight-loss medications (Rx and OTC) (Petty and Cacioppo, 1983, 1986; Sewak, 2002, Sewak, et al., 2005). All eight story-based treatment scenarios were randomly assigned, and given to all participants. Statistical analysis consisted of a 2x2x2 design (ANOVA). Analyses of source of information and type of weight-loss medication were crossed with source of information communication type (positive versus negative) in each scenario. Null hypotheses were rejected (H1 - H8). As expected, the physician was the over-all stronger source. However, positive CPT communication and higher credibility score, led to an increase in intention. This is a significant finding. If consumers perceive CPTs to be as knowledgeable as MDs (outside of CPT expertise in exercise planning, prescription, and training); consumers would view CPTs as a credible, reliable, and alternative source for weight-loss related areas of interest and concern.","abstract_html":"In health-related behavioral decision-making, the Theory of Planned Behavior (TPB) posits that attitudes toward a behavior are the function of three metrics: beliefs and strengths of beliefs toward the behavior, subjective norms around the behavior and locus of control for the individual (Ajzen, 1988).
