International students' needs and experiences in counseling training and supervision has been an area of interest for several decades; however, there is a lack of research regarding effective approaches for supervising international students. Previous studies concerning the international counseling student population have mainly utilized bivariate analysis, and inconsistent results have been observed among studies examining the same relations, which makes applied implications questionable. More complex analysis to determine the relationships among constructs, which will assist in applied implications, are long needed. Thus, this study was a response to the need to determine if a moderation effect could be observed among key counseling supervision-related variables. The purpose of this study was to investigate whether international counseling supervisees' perceptions regarding the degree to which the construct of multicultural discussion occurring in their university supervision moderated the relationship among key supervision-related variables, including acculturation, counselor self-efficacy, supervisory working alliance, and role ambiguity in supervision.
