Re: Are antidepressants overprescribed? No
Reid quotes the study by Fountoulakis & Möller (2011) that provided a re-analysis and re-interpretation of the Kirsch data and concludes, "Sadly, demonstrations of methodological flaws and selective reporting suggest that the conclusions [of Kirsch] were 'unjustified.'" However, he failed to cite the response by Kirsch et al (2012)  which shows that the original calculations were in fact correct. The discrepancy comes from Fountoulakis & Möller treating individual studies as though they are equivalently powered. This is contrary to the standard meta-analytic technique of weighting studies with a large sample size more than the ones with a small sample size.
