A Systematic Review of the Effectiveness of Group versus Individual Treatments for Adult Obesity
Open accessAbstract
BACKGROUND: Both group and individual modes of delivery are employed for obesity treatments. Commercial weight loss groups commonly employ group-based delivery, while many clinical based settings employ one-to-one delivery. We systematically reviewed randomised controlled trials of treatments for adult obesity to compare the effectiveness of group-based to individual-based modes of treatment delivery. METHODS: We searched 7 electronic databases and 2 journals and reviewed secondary references, based on a priori criteria to systematically review: randomised controlled trials of obesity treatments, participants with BMI >or=28 kg/m(2), age >or=18 years, comparison groups including at least 1 group-based and 1 individual-based treatment group, and follow-up >or=1 year. We extracted data and conducted meta-analysis of weight change. RESULTS: Eleven comparison groups from 5 qualifying trials were obtained, representing a total participant pool of 336. Significantly greater (p = 0.03) weight change at 12 months was found in group-based over individualbased treatment, and sub-analyses showed that increased effectiveness was associated with the use of financial reward and psychologist-led interventions. CONCLUSION: Group-based interventions were more effective than individual-based interventions among a predominantly female participant pool receiving psychologist-led interventions. Future studies to explore differences by professional group and interventions among men, which are accompanied by economic evaluation, are recommended.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
