I want to aggregate the opinions declared on the need for school-based management measured in a 5-point Likert scale, e.g. where to decide on HRM, where to decide budget allocation, etc. Almost all analysis gives the results in frequencies(f) or mean and standard deviations. So, what method of meta-analysis do you recommend to aggregate the studies?See More

A message from Nina Lasek to all members of Meta-analytic structural equation modeling on Meta-Analysis Resources! Dear meta-analysers (hope it is correct to post my question here?), I replicated a moderated mediation path model across k=11 samples. Indicators and sample sizes (individual data are available, n from approx. 1000 to approx. 2000) differ. But all associations including the moderation of the mediation are in the expected direction. Currently, the moderation is calculated as a product term using Mplus. I could also do a multigroup analysis with the moderator as grouping variable. Then i would have e.g. two or three groups per sample. Question is whether such models - either a path model with moderated indirect effects or a multigroup path model with an indirecte effect - might be meta-analysed as MASEM? Or, perhaps alternatively, I was also thinking about using the regression weights indicating the mediated respectivey the moderated mediated effects as univariate information for a 'conventional' meta-analysis. What do you think? I would be very grateful for tips with regard to applied examples. Many thanks in advance, N.See More

Dear All,I am learning to do a meta-analysis and I have a question on studying interaction effects with meta-analysis. If my primary studies have 3 variables A, B and C and its correlations with variable D. If my hypothesis, based on theory, is that strength of the relationship between A and D is dependent on B. B is the moderator in this case. Is there any way I can do a meta-analysis to test this?. See More
