Individual research studies are great. But even better is when someone takes these studies and puts them together to see if one study shows the same thing another does, and if they do is the effect size consistent? Sometimes you can only do this by going old school and pooling the data from the individual studies. This is especially helpful in determining the effectiveness of different interventions. This week, Dr. Matthew Lerner and his colleagues at Stony Brook University published a meta analysis of group social skills interventions. They put together well-designed studies and asked: do they work? Are they better than getting nothing at all? To find out, listen to this week’s ASF podcast.
