title: Identifying randomized controlled trials of cognitive therapy for depression: comparing the efficiency of Embase, Medline and PsycINFO bibliographic databases.
abstract: This study sought to compare the sensitivity and precision of Embase, Medline and PsycINFO bibliographic database searches for randomized controlled trials of cognitive therapy for depression. Searches in each database combined with a hand search in five selected journals formed the total pool against which each search was assessed. Sensitivities of standard searches (index terms only) were 68%, 84% and 38% in Embase, Medline and PsycINFO respectively. Sensitivities of expert searches (index and free text terms) were 76%, 97% and 65% for Embase, Medline and PsycINFO respectively. Medline appears to be the most efficient at identifying articles describing psychological treatment evaluation.
