Explanation / Answer
Experiments using repeated measures design, sometimes also called within-subject designs, make measurements using only one group of subjects, where tests on each subject are repeated more than once after different treatments.
Repeated measures design means that you don't have to have separate control groups and treatment groups because the same group is both the control and is exposed to ALL the treatments, just at different times.So, it's applicable here.
Here , John can apply that technique.
##
who : the victimes.
1st observation before the programme
2nd observation after the programme
what : measuremnt of DV score that we would specify in next ection.
Then collect the two means. and text for equality of mean. apply t test
##
measure of DV score:
make a questionere .
eg.
Do you still see bad dreams about past DV ? etc.
like a total of 20 questions.
now put weight to the questions.
an 'yes' would score '1'. and a 'no' would score '0' !
