here level of significance is not given . let it is alpha=0.05 ( generaly alpha=0.05) is taken.
here p-value=0.047 of the group is less than alpha=0.05, so we reject the null hypothesis that all the group means are same.
multiple comparison showed that p-value=0.015 of difference of CBT and narrative therapy, this means this pair is significantly different to each other. but other two pairs are not significantly different to each other.
