Abstract
OBJECTIVES: The intention to include a category of Complex Posttraumatic Stress Disorder (CPTSD) in ICD-11 has renewed interest in this construct. Although growing evidence from high income countries supports the construct validity of CPTSD, little parallel research has been undertaken across cultures. We tested theoretically supported CPTSD structures (a one-factor, six-factor, one-factor higher-order, and two-factor higher order structure) in a community sample of West Papuan refugees living in a remote town, Kiunga, in Papua New Guinea (PNG). PROCEDURES: A community-wide survey was conducted (2016-2017; response rate 85.5%) amongst 486 West Papuans. Culturally adapted measures were applied to assess cumulative traumatic exposure, postmigration living difficulties (PMLDs), CPTSD symptoms, and functional impairment. FINDINGS: A six factor structure for CPTSD provided the best fit to the data, consistent with our past study amongst West Papuans. CONCLUSIONS: The cross-cultural validity of our findings is supported by the isolation of West Papuan participants from services treating traumatic stress. To further support the universal applicability of CPTSD, our findings need to be confirmed amongst other refugee groups from diverse cultural backgrounds.
