Values are the observed mean (SD); all comparisons are adjusted for sex, age, and BMI. Note: CG: control group; EG: experimental group; ¥reverse scoring; amean between-groups difference with 95% confidence interval based on estimated marginal means adjusted for sex, age, and BMI; bmean within-group changes with 95% confidence interval based on estimated marginal means adjusted for sex, age, and BMI; : partial eta squared; difference between CG and IG; difference between CG and EG; # difference between pre- and posttest; ## difference between pre- and posttest.
