• A)Levene's test was non-significant,F(2,12)= .82,p = .47,and so the results must be treated with caution.

• C)The type of therapy administered had a significant effect on stress levels,even after baseline levels of stress had been accounted for,F(1,11)= 23.16,p < .001.
• D)The type of therapy administered had a significant effect on stress levels,even after baseline levels of stress had been accounted for,F(2,11)= 5.98,p = .017.
