This study sought to empirically test segments 2 and 3 of Lidderdale et al.'s (2007) Social Cognitive Career Theory (SCCT) based model of workplace sexual identity management (WSIM). Workplace sexual identity management refers to the way in which sexual minority individuals make decisions regarding the disclosure of their sexual identity in their workplace. In conjunction with testing this model, this study also sought to improve upon methodological and sampling issues present in previous studies of sexual minority participants (Croteau, 1996). It was hypothesized that variables similar to those of SCCT (learning experiences, outcome expectations, self-efficacy, and contextual influences) would predict, both directly and indirectly, employee's range of acceptable WSIM strategies, strategy intentions, and actual disclosure behaviors. Participants were a national sample of sexual minority individuals who were currently employed 15 or more hours per week and who successfully completed an online survey. Structural equation modeling was used to examine model-data fit. The original SCCT-based model achieved poor fit; however, a revised version of the model eliminating nonsignificant paths and adding three suggested paths achieved excellent fit to the data (χ 2 = 5.86, p = .21; CFI = .997; RMSEA = .05; SRMR = .03). Results thus provide support for the use of an SCCTbased model of WSIM. Limitations of the present study, relevant sampling and measurement issues, and implications for future research and professional work are discussed.
