Subclaims¶

q3 i? Intervention teachers showed a significant interaction and significant pre-to-post increase in nutrition outcome expectations, scoring significantly higher than control teachers at post. → Fahlman M 2011 q2 i? Intervention teachers had higher outcome expectations on all 11 individual measures, including beliefs that students would eat a diet low in fat and change unhealthy eating habits. → Fahlman M 2011 (2)

Evidence¶

Fahlman M 2011¶

Fahlman M, McCaughtry N, Martin J, Shen B. (2011). School health educators' self-efficacy, intentions to teach, and implementation of nutrition education increases after in-service training. Am J Health Educ. 2011;42(3):181-190. https://doi.org/10.1080/19325037.2011.10599191

q3 · i? · causal · r2

Repeated-measures ANOVA on the 59-teacher quasi-experimental sample for the outcome-expectations subscale; total outcome expectations rose from 28.6 to 51.9 in the intervention group versus roughly 27.4-27.5 in controls. The article reports a "significant interaction" between groups across testing times.

"There was a significant interaction. Teachers who participated in the in-service had a significant increase in outcome expectations from pre-to-post (F = 8.62, P = 0.001) and significantly higher outcome expectations than the control teachers' post."

q3 · i? · causal · r2

Item-level ANOVAs on the same sample: all 11 outcome-expectation items showed significant intervention gains, e.g., eat a diet low in fat (F = 13.21, P < 0.001) and change unhealthy eating habits (F = 9.43, P = 0.001).

"The intervention teachers also had higher outcome expectations on all 11 of the individual measures. They were more likely to believe that if they did a good job teaching, their students would maintain a normal weight (F = 6.48, P = 0.023), eat according to the food pyramid (F = 5.58, P = 0.018), eat five fruits and vegetables a day (F = 5.65, P = 0.030)"
