Objective:
To determine nutrition practitioners' attitudes, behavioural control and normative beliefs to best inform the development and formulation of a nutrition-specific Dissemination and Implementation (D&I) science training.
Design:
A cross-sectional survey aimed to assess Theory of Planned Behaviour (TPB) constructs and intention to use D&I science. A validated TPB questionnaire assessed constructs including perceived behavioural control, subjective, injunctive and descriptive normative beliefs, attitudes and intention to use D&I science. For analysis, Spearman's ρ, Kruskal-Wallis and Steel-Dwass tests were conducted for quantitative variables.
Setting:
Online, 26-item Qualtrics survey.
Participants:
Cross-sectional sample of members (n 70) affiliated with the Society for Nutrition Education and Behaviour listserv.
Results:
The major finding from this study was a significant positive correlation between perceived behavioural control score and intention (r = 0·315, P = 0·0119).
Conclusions:
D&I training interventions could formulate learning and teaching strategies to target perceived behavioural control (self-efficacy, knowledge and ability) to enhance intention. For example, application and experience-based learning techniques trainings could be strategies to increase knowledge and abilities.
