Future counselors are likely to work with clients with process/behavioral addictions (PBA). The behavioral addiction knowledge survey (BAKS) was designed to determine counseling students’ knowledge of PBAs. This article presents the instrument development procedures and results of a preliminary exploratory factor analysis (EFA) and a Rasch analysis of the BAKS. The sample size included 77 counseling students. The EFA suggested a three-factor, 18-item solution, with satisfactory internal consistency within each factor. Rasch analysis results also yielded excellent infit and outfit statistics. Detailed psychometric properties of the BAKS are provided. Implications for counselor educators, supervisors, and future researchers are included.
