Scholars (e.g., Bemak & Chung, 2004) underscore the need for group workers to be culturally sensitive. One group training strategy, cultural immersion, is often employed to develop cultural sensitivity. However, no studies have utilized quasi-experimental methodologies to assess differences in cultural sensitivity between trainees that immerse compared to those that do not immerse. To this end, this article provides an overview of the Developmental Model of Intercultural Sensitivity, description of an international cultural immersion experience and quasi-experimental research design, analysis of data, discussion of results, implications for group facilitators and counselor educators, and suggestions for future research.
