Applying social cognitive career theory to registered dietitian research involvement: a randomized controlled trial

The purpose of this study was to measure the effect of a social cognitive career theory (SCCT)-based educational intervention combined with an evidence-based practice (EBP) continuing professional education (CPE) program (standard-plus group) as compared to the EBPCPE program alone (standard group) and a no-treatment control on research outcome constructs (research self-efficacy, research outcome expectations, research interest and research involvement) in dietitians.

This randomized controlled trial measured the effect of an online 14-week educational intervention, with measurements made pre- and post-intervention and at 3-month follow-up. A randomly selected list of registered dietitians (RDs), who reported clinical nutrition as their primary practice area, was obtained from the Commission on Dietetic Registration. Subjects (n=580) were randomly assigned to three study groups, and 47.2% (n=272) completed data collection.

The treatment effect between the groups was significantly different for research self-efficacy (p<0.001) and research involvement (p=0.005), with positive effects observed in the standard-plus and standard groups. There were no significant effects for research outcome expectations and research interest.

This is the first known application of SCCT to RD research involvement as a career-related behavioral outcome, and it demonstrated that a significant increase in research self-efficacy occurs following participation in an educational intervention on EBP.
