Comparison of Body Image Acceptance Mean difference (SE) Z p value (1- Effect size
1. Low EDR compared to
tailed) (Cohen’s d)
Moderate EDR
2.36 -0.28 0.39 0.08
2. Low EDR compared to High
EDR
3. Moderate EDR compared to
High EDR
58.49 -3.29 0.00 1.87
56.13 -2.85 0.00 1.87
As can be seen from the above table there is a significant difference between the low
EDR group as compared to the high EDR group and a significant difference between the
moderate EDR group as compared to the high EDR group. This is as was predicted thus
confirming the hypothesis that the low EDR group will have higher body image
acceptance than the moderate and high risk groups. The effect sizes of the low EDR
group compared to the high and for the moderate EDR group compared to the high EDR
group are large (i.e. 1.86). The effect size for the low EDR compared to the moderate
EDR is very small.
The next set of hypotheses, consider inflexibility, body image acceptance, depression and
anxiety in relation to the BMI groups.
