| Popis: | In 2001, Debbie Lawlor along with co-author Stephen Hopker, published an influential and highly cited meta-analysis in the British Medical Journal in which they examined the effectiveness of exercise as an intervention to treat depression (Lawlor & Hopker, 2001). They identified 14 studies, all of which had what they considered important methodological weaknesses. Nevertheless, in studies that compared exercise to no treatment controls, the pooled standardized mean difference in effect size was −1.1. Pooling the nine studies that used the Beck Depression Inventory (BDI) yielded a weighted mean difference score of −7.3. However, despite this relatively large effect (i.e., most drug and psychotherapy trials report less than a −4.0 mean difference score; Lesperance et al., 2007; Schneider et al., 2003) the authors concluded that the effectiveness of exercise in reducing symptoms “cannot be determined because of a lack of good quality research on clinical populations with adequate follow up” (Lawlor & Hopker, 2001, p. 763).. |
