World assumptions and their role when facing trauma in urban Sierra Leone: a complementary mixed methods study

Concerns have been raised about the cross-cultural applicability of Western-centric models of world assumptions, questioning their universality, patterns and role when facing trauma. Within a trauma-focused research project in Sierra Leone, this sub-study examines these issues in the local context.

We conducted a qualitatively driven mixed methods study (embedded design) from an emic-etic perspective. Qualitative interviews explored the assumptive worlds of 16 students, while questionnaires examining how assumptions were affected by trauma were completed by 280 students. All participants had experienced traumatic events (DSM-5). In addition, four expert interviews were conducted to address both aspects.

The concept of world assumptions (benevolence, meaningfulness, self) was found to be relevant in the Sierra Leonean sample; however, the patterns differed from those typically documented in Western societies. Additional assumptions concerning the self, the world, others, and meaningfulness were identified. Quantitative results indicated that participants' assumptive worlds were challenged by trauma, shaping their personal life stories and identities.

To strengthen culturally sensitive investigations, we propose renaming certain domains and dimensions to more neutral and inclusive ones, and considering additional facets. This study contributes to a more nuanced understanding of world assumptions and their role in diverse cultural contexts.
