HYPNOSIS TO MANAGE DISTRESS RELATED TO MEDICALPROCEDURES: A META-ANALYSIS

摘要

This meta-analysis evaluates the effect of hypnosis in reducing emotional distress associ-ated with medical procedures. PsycINFO and PubMed were searched from their incep-tion through February 2008. Randomized controlled trials of hypnosis interventions,administered in the context of clinical medical procedures, with a distress outcome, wereincluded in the meta-analysis (26 of 61 papers initially reviewed). Information on samplesize, study methodology, participant age and outcomes were abstracted independentlyby 2 authors using a standardized form. Disagreements were resolved by consensus.Effects from the 26 trials were based on 2342 participants. Results indicated an overalllarge effect size (ES) of 0.88 (95% CI = 0.57-1.19) in favour of hypnosis. Effect sizesdiffered significantly (p < 0.01) according to age (children benefitted to a greater extentthan adults) and method of hypnosis delivery, but did not differ based on the controlcondition used (standard care vs. attention control).
