This study investigated the efficacy of utilizing comprehensive database search strategies in performing an online literature search in the subject area of psychology, with special interest in the performance of the database PsycInfo. The DIALOG Information Retrieval Service's DIALINDEX subject category options were used as the major search vehicle to determine the number of relevant "hits" in each of several databases and to ascertain redundancy of citations across the databases. Databases for the DIALINDEX subject categories of PSYCH including PsycINFO) and MEDICINE were accessed with two sample searches using the descriptors psychopathology/social influences and psychopathology/social class. The results of these searches was that databases other than PsycINFO (Excerpta Medica and Medline) also provided relevant citations, and that overlap of citations between the databases was negligible. The findings suggest that online literature searches involving psychological topics should include comprehensive database strategies. Several major commercial services offer such multi-database options. (Author/THC)
