The hypothesis that higher inflexibility will be associated with lower body image
acceptance was supported, Pearson’s, r = -0.55, p = 0.00, (n=81). Furthermore, there was
a significant association between EDR and inflexibility, such that the high and moderate
EDR groups were more inflexible than the low EDR group, high compared to low EDR z
= -1.67, p = 0.05, Cohen’s d = 0.71 Moderate compared to high EDR z = -0.19, p = 0.43,
Cohen’s d = 0.61 confirming the main hypotheses. Moreover, the effect sizes were
between medium and high (0.71 and 0.61).
There was a significant difference between the low and moderate EDR groups as
compared to the high EDR group regarding body image acceptance. Low compared to
high EDR group z = -3.29, p = 0.00, Cohen’s d = 1.87. Moderate compared to high EDR
group z =-2.85, p = 0.00, Cohen’s d = 1.87. The effect sizes of the low EDR group
compared to the high and for the moderate EDR group compared to the high EDR group
were large (1.87).
The second set of hypotheses considered BMI groups in relation to inflexibility, body
image acceptance, depression and anxiety.
Hypotheses II
No significant difference was found in inflexibility between the underweight and
overweight groups as compared to the healthy BMI groups. There was also no significant
difference in body image acceptance in the underweight and overweight groups as
compared to the healthy BMI groups. There was however a significant mean difference
between the healthy as compared to the underweight group on their levels of depression
but not on anxiety. There is also a mean difference between the overweight and healthy
group as regards depression but not on anxiety. The effect sizes for underweight and
overweight BMI in relation to depression were medium (0.6 and 0.4 respectively).
The third set of hypotheses investigate depression and anxiety in relation to inflexibility,
body image acceptance and EDR.
