Abstract
Background

Following years of controversy, a category of complex post-traumatic stress disorder (CPTSD) will be included in the forthcoming ICD-11.

Aims

To test whether refugees with CPTSD differ from those with other common mental disorders (CMDs) in the degree of exposure to childhood adversities, adult interpersonal trauma and post-traumatic hardship.

Method

Survey of 487 West Papuan refugees (response rate 85.5%) in Papua New Guinea.

Results

Refugees with CPTSD had higher exposure to childhood adversities (CPTSD: mean 2.6, 95% CI 2.5–2.7 versus CMD: mean 1.15, 95% CI 1.10–1.20), interpersonal trauma (CPTSD: mean 9, 95% CI 8.6–9.4 versus CMD: mean 5.4, 95% CI 5.4–5.5) and postmigration living difficulties (CPTSD: mean 2.3, 95% CI 2–2.5 versus CMD mean 1.85, 95% CI 1.84–1.86), compared with those with CMDs who in turn exceeded those with no mental disorder on all these indices.

Conclusions

The findings support the cross-cultural validity of CPTSD as a reaction to high levels of exposure to recurrent interpersonal trauma and associated adversities.
