Abstract
Health messages framed to be congruent with individuals’ approach/avoidance motivations have been found to be more effective in promoting health behaviors than health messages incongruent with approach/avoidance motivations. This study examines the processes underlying this congruency effect. Participants (undergraduate students, N=67) completed a measure of approach/avoidance orientation (the BIS/BAS scales) and read either a gain- or loss-framed message promoting dental flossing. Results demonstrated a congruency effect: Participants who read a congruently framed message had greater flossing efficacy, intended to floss more, and used more dental flosses than did the participants who read an incongruent message. Moreover, intention to perform the behavior predicted the congruency effect and self-efficacy mediated participants’ intentions to perform the health behavior. Discussion centers on the role of personality factors and situational factors in models of behavior change.

Notes
Prior to reading the health article, participants first completed a computer-based anagram-solving task. There was a manipulation embedded in the anagram task. Half of the participants were given one ticket for every anagram they got correct (up to 10), and half of the participants were given 10 tickets, and one was taken away for every anagram they got incorrect. The manipulation did not affect flossing behavior or intentions and will not be mentioned further.
We tested our interaction hypothesis using two-way ANOVA and a categorical, rather than continuous, operationalization of motivational orientation. As our main dependent measure (flossing) showed substantial deviation from normality, ANOVA allows for a more robust test of the hypotheses as compared to moderated multiple regression. However, to ensure that our results were not simply an artifact of analytical procedure, we replicated the interaction by recoding the flossing measure into three roughly equal categories, and used ordered logit regression with a continuous (BIS minus BAS) rather than categorical measure of motivational orientation (interaction coefficient=−1.92, SE=.88, Z=−2.17, p=.03).
In all steps of the mediational analyses, the main effects of message frame and motivational orientation were included, but are not reported for the sake of brevity.
