The Brief COPE is a widely used measure of coping that contains 28 items on 14 factors. Researchers have shortened the inventory, but the factor structure remains debated. A systematic review of peer-reviewed studies published in English between 1997 and 2021 was conducted to determine if a more parsimonious number of factors could be identified. Cumulative Index for Nursing and Allied Health, PsycINFO, PsycARTICLES, Medline, PubMed, and Scopus databases were searched using keywords "Brief COPE" and " factor, valid*, or psychometric.*" Searching yielded 1,303 articles; cited references added 38; 85 articles met inclusion criteria. Principal components analysis and confirmatory factor analysis were major analytic strategies used (28% and 27%, respectively). Only eight studies analyzed the original 14-factor structure. Factors identified ranged from 2 to 15, with dichotomous factors most frequently identified (25%; n = 21). A smaller number of factors may be able to represent the Brief COPE. Research is needed to test a condensed instrument. [ABSTRACT FROM AUTHOR]
