These are widely different groups at pre-test. I would be concerned
about the randomization procedure. Of course SD will not produce much
change when everyone entering that treatment has a low score to begin with.

Hi everyone,
i was wondering if there is anyone out there who can help me. I have a
pretty simple task, but i am new to spss and i need help and quickly.
I have three groups of participants each group went through a
different type of therapy for anxiety. The groups have unequal numbers
(12, 14, and 10). Phobioa scores were taken before and after
treatment. I am using a general linear model procedure to test the
change in the scores, equal variences are assumed and the assumption
of normality was met.
I found that there is a significant difference between two of the
groups (EMDR and SD) using a post hoc test (bonferroni), however i
need to know which group is the best at reducing anxiety? how do i do
this? if you know, can you tell me exactly how to do it on spss
version 11?? please help ASAP!!!
i will include my data incase it helps.
Participant, Gender, Age, Therapy technique, Score before therapy,
Score after therapy, change in score.
