A cross-cultural team including a U.S.-trained clinical cross-cultural psychologist and two Turkish psychiatrists conducted research on a set of five trauma treatment psychotherapy groups for adult women survivors of sexual abuse in Ankara, Turkey. Based upon observational comparisons between trauma treatment groups in U.S. and Turkish settings, the team developed an approach to assist in adaptation of treatment methods from one cultural setting to another. This is a preliminary effort to develop a conceptual tool to focus the attention of therapists on salient dimensions of culture that may influence the psychotherapy process. This article describes six possible dimensions: (a) relational/individual self; (b) situationalism/universalism; (c) high/low power differential; (cc) high/low gender differential; (d) internal/external control; (e) emotional expressivity/containment; and (f) short-term/long-term time orientation. Comparative cultural examples from trauma psychotherapy group field notes illustrate the use of the tool.
