Using the health belief model, how can nurses encourage patients to make immediate and permanent behavior changes; particularly as they relate to lifestyle choices?

The Health Belief Model (HBM) posits that messages will achieve optimal behavior change if they successfully target perceived barriers, benefits, self-efficacy, and threat. While the model seems to be an ideal explanatory framework for communication research, theoretical limitations have limited its use in the field. Notably, variable ordering is currently undefined in the HBM. Thus, it is unclear whether constructs mediate relationships comparably (parallel mediation), in sequence (serial mediation), or in tandem with a moderator (moderated mediation). To investigate variable ordering, adults (N = 1,377) completed a survey in the aftermath of an 8-month flu vaccine campaign grounded in the HBM. Exposure to the campaign was positively related to vaccination behavior. Statistical evaluation supported a model where the indirect effect of exposure on behavior through perceived barriers and threat was moderated by self-efficacy (moderated mediation). Perceived barriers and benefits also formed a serial mediation chain. The results indicate that variable ordering in the Health Belief Model may be complex, may help to explain conflicting results of the past, and may be a good focus for future research.

As one of the most widely applied theories of health behavior (Glanz & Bishop, 2010), the Health Belief Model (HBM) posits that six constructs predict health behavior: risk susceptibility, risk severity, benefits to action, barriers to action, self-efficacy, and cues to action (Becker, 1974; Champion & Skinner, 2008; Rosenstock, 1974). Originally formulated to model the adoption of preventive health behaviors in the United States, the HBM has been successfully adapted to fit diverse cultural and topical contexts (e.g., Griffin, 2012; Scarinci et al., 2012).

Widely used in other fields, the HBM would seem to be ideal for communication research. Surprisingly, the HBM is utilized less frequently by communication scholars. Communication researchers are primarily interested in explicating communication processes, an objective that favors explanatory frameworks (Slater & Gleason, 2012). As an explanatory framework, the HBM has significant

limitations. Notably, researchers have argued that the HBM fails to specify variable ordering (Champion & Skinner, 2008). This limitation is significant for researchers interested in utilizing the HBM to understand communication processes, as numerous process-oriented questions are raised by the model that currently have no answer. For example, it is possible that all six variables serve as equivalent mediators (parallel mediation; see Champion et al., 2008), that some variables form sequential or serial chains (serial mediation; see Janz & Becker, 1984), or that variables are hierarchically situated so that some moderate the mediational influence of others (moderated mediation; see Champion & Skinner, 2008). Unfortunately, these different models are rarely examined or compared in the literature (Champion & Skinner, 2008).

The current study seeks to advance the HBM as an explanatory framework for communication research (Slater & Gleason, 2012) by examining three possible models (parallel, serial, moderated mediation) in the evaluation of an H1N1 vaccination campaign. A single campaign evaluation cannot validate a particular model, but it can compare the veracity of each model within a particular context and provide a template for process-oriented HBM research. The latter is needed, as researchers have not pursued this question despite frequent calls for process-oriented research (e.g., Champion & Skinner, 2008; Strecher, Champion, & Rosenstock, 1997). The results of this research will be especially useful to scholars interested in testing the direct and indirect effects of messages grounded in the HBM.
