Impact: Control vs. Treatment

▪For actors and viewers, posttest scores were significantly higher than pretest scores on

  MyPlate knowledge and nutrition exercise knowledge (p<.001)

ANCOVAs comparing group's posttest scores with pretest scores as covariate

▪Posttest knowledge scores and MyPlate scores were significantly (p<.001) higher for the treatment (musical) group than control group (no musical) after controlling for pretest.

▪Knowledge scores and MyPlate scores significantly (p<.001) increased from pretest to posttest for the treatment (musical) group, but not the control group.

Evaluation of Student Actors & Viewers

We evaluated the effectiveness of a school-based, educational theater program (i.e., MyPlate Musical) on nutrition/exercise knowledge of elementary student performers and viewers. Data were collected in four elementary schools with high percentages of Latinos and students eligible for free/reduced price meals. In Schools 1–3, pretest and posttest data were used from a total of 425 viewers and 220 performers. At School 4, 267 viewers and 75 performers served as their own control. Results indicated that student performers and student viewers of the theatrical performances had increased general nutrition/exercise knowledge and MyPlate knowledge from pretest to posttest and the effects were stronger in the treatment group than the control group. Educational theater appears to be a viable method to increase nutrition/exercise knowledge.
