Hi,
Here's an extract from a paper I'm using in a systematic review:
The mean GAD-7 score of the sample prior to the course was 10.98 (SD 5.17, range 0–21). The mean GAD-7 score after the online mindfulness course was 5.45 (SD 3.77, range 0–19) and at 1 month follow-up 4.60 (SD 3.72, range 0–21). A repeated measures ANOVA indicated that the mean GAD-7 score changed significantly precourse to postcourse (F(1.71,465.4) =325.53, p<0.001) and post hoc tests using the Bonferroni correction revealed that GAD-7 score also further significantly decreased at 1 month follow-up, mean difference post to follow-up 0.850, standard error 0.211, p<0.001.
Does it not indicate that the scores changed significantly at some point between the precourse and follow up measure? Hence the post hoc analysis to find out where this is true?
Thanks for your help,
James
