Healthy Outcome for Teens (HOT project): Change in Social Cognitive Theory constructs in a randomized control trial

The objective of the HOT project: Healthy Outcome for Teens was to compare a control group (n=104) with passive online learning [POL] and a treatment group (n=129) with active online learning [AOL] for the exercise outcome expectancies (EOE), nutrition outcome expectancies (NOE), exercise self‐efficacy (ESE), weight efficacy lifestyle (WEL), planning a meal (PM), and rapid eating assessment (REA) questionnaires. Cronbach alpha was calculated on baseline data: EOE (12 items) = 0.849, NOE (20 items) = 0.783, ESE (6 items) = 0.961, WEL (18 of 19 possible items) = 0.929, PM (5 items) = 0.439, REA (26 items) = 0.816. Composite scores for all except PM questionnaire were computed and used for analysis. There were no significant differences in baseline scores except NOE (POL vs AOL). Significant improvements in 3 items for PM were found (Starch: control, 0.42 ± 0.50 and treatment, 0.57 ± 0.50; Fruit: control, 0.31 ± 0.47 and treatment, 0.52 ± 0.50; Beverage: control, 0.52 ± 0.50 and treatment, 0.71 ± 0.45). Control (POL) EOE was significantly more positive than treatment. No significant differences were found for WEL, ESE, REA. For skill in PM, AOL had a greater effect than POL.
