[R-meta] Compiling different design in the same met-analysis

Dear all,

I am doing a meta-analysis on experimental data on the impact on
several behavioral interventions including both *pre-post studies*
(measurement of a trait before and after the intervention) *and control vs.
treatment studies *(measurement after a control intervention vs.
measurement after the intervention).
I am interested in the effect size of each type of intervention on a
specific trait that is common to all studies.

I would like to know whether it is correct to compile all studies from one
type of intervention (whatever the type of comparisons: pre-pot and control
vs. treatment group together) with pre- and control being as control and
post and treatment being as treatment.

I have a second question about how to thank the
r-sig-meta-analysis at r-project.org list for all their help
(acknowledgements in a paper).

Thanks a lot for your help!

Have a great day,

Gladys
