Cultural psychological factors in posttraumatic symptom development and expression: a study protocol.

Introduction: Cultural factors were shown to be particularly relevant for the development and expression of posttraumatic stress. Recently, the concept of cultural scripts of trauma has been introduced, which proposes that trauma sequelae elements may be sequentially linked and specifically associated with cultural factors. Furthermore, a cascade model is proposed, including trauma exposure, demographic characteristics, cultural affiliation, and trauma-related value orientations as influencing factors of posttraumatic development. The purpose of this Network Project is to investigate cultural psychological factors that contribute to the expression of posttraumatic stress.Methods: The present Network Project implements a mixed methods approach and will be conducted in 5 different study sites, including Switzerland, Israel, Georgia, China, and East Africa. In sub-study I, the cultural scripts of traumatic stress inventories (CSTIs) will be developed. These scales provide a pool of trauma sequelae elements for each cultural group. For this purpose, focus groups with trauma survivors and trauma experts will be conducted and analysed using qualitative research methods. Sub-study II implements a validation analysis of the CSTIs and the empirical investigation of a cultural cascade model. This quantitative approach will include a larger sample of individuals who experienced traumatic life events.Discussion: This contribution is timely and enriches the knowledge of trauma and culture. Future publications of this Network Project will address trauma sequelae from a cultural perspective and provide diagnostic and psychotherapeutic implications.
