Lent and Brown proposed a social cognitive career self-management process model that extended prior social cognitive career theory (SCCT) content models to explain the conditions under which people will engage in career management behaviors (e.g., career exploration). We tested the SCCT self-management model in the context of workplace sexual identity management. The model hypothesizes that engagement in sexual identity management strategies in the workplace is facilitated by strong sexual identity management self-efficacy beliefs and positive outcome expectations for engaging in sexual identity management behaviors. The model also posits that additional person and contextual variables will influence engagement in sexual identity management behaviors directly as well as indirectly via self-efficacy beliefs and outcome expectations. Using a sample of 152 sexual minority participants drawn from community Internet mailing lists, partial and full mediation models of workplace sexual identity disclosure were tested using theoretically relevant person input (i.e., concealment motivation) and contextual (i.e., workplace climate) variables. Results supported a partially mediated model suggesting that concealment motivation and workplace climate influence workplace disclosure directly as well as indirectly through self-efficacy and positive outcome expectations. Policy and social justice implications for the results are discussed and future research directions are considered.
