Abstract

OBJECTIVE: To examine attrition variables in randomized controlled trials of cognitive behavioral interventions for children with chronic illnesses. METHODS: We examined attrition rates reported on 40 randomized cognitive behavioral interventions published in six pediatric research journals, during the years 2002-2007. Intervention focus was limited to children with a chronic medical condition, such as asthma, obesity, arthritis, diabetes, cancer, sickle cell disease, and cystic fibrosis. RESULTS: Mean rate of enrollment refusal was 37% (range 0-75%). Mean attrition rate was 20% (range 0-54%) for initial follow-up and 32% (range 0-59%) for extended follow-up. Of the reviewed articles, 40% included a CONSORT diagram. CONCLUSIONS: Strategies that can be used to limit attrition include tailoring recruitment to the study population, providing personalized feedback, maintaining consistent study procedures, providing incentives, and using intensive tracking measures. There is a need for standardized definitions and reporting of attrition rates in randomized cognitive behavioral intervention studies.

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.
