Abstract

Objective: This study was a formative evaluation of modules related to Green Eating. Perceptions of the motivational value of the modules were assessed.

Design: This study was a cross-sectional study using secondary data.

Participants: 224 college students.

Intervention: Participants completed one of three online modules. Participants established a goal for the module they viewed and determined their self-efficacy (SE) in meeting their goal.

Main Outcomes: Motivational value was assessed using the Instructional Materials Motivation Survey (IMMS); IMMS scores were compared between modules. Goal congruency (relationship to module topic) and SE were compared between modules.

Analysis: Differences in IMMS score and SE were compared between modules using Analysis of Variance. The proportion of IMMS scores ≥3.5 (defined as motivating) and the proportion of goals that were congruent to the module were compared using Chi-Square analysis. Differences between goal congruence and SE and differences in stage of change (SOC), IMMS score, and SE were assessed.

Results: Average IMMS total score was ≥3.5 for each module, with no difference in IMMS score between modules. The majority of participants had an IMMS score ≥3.5. The majority of goals were congruent to the module that was viewed and participants were moderately to mostly confident in meeting their goal.

Conclusion: The modules were motivating to participants and they were able to establish a goal that was congruent to the module that they viewed.

Key Words: formative evaluation, green eating, IMMS, motivational value, self-efficacy.
