College students (20 women, 14 men) seeking career counseling services at a university career center participated in this exploratory investigation. A 2 (DISCOVER treatment) x 2 (counseling treatment) research design was used to evaluate the individual and combined effects of DISCOVER (ACT, 1998) and counseling on participants' career decision-making self-efficacy and career decision-making attributional style. Findings revealed a significant effect of the use of DISCOVER on participants' career decision-making self-efficacy and their sense of control over the career decision-making process. Results are discussed regarding the implications for career counseling and ideas for further research in this domain. (Contains 1 table.)
