The primary outcome measure was severity of PTSD-symptoms (Harvard Trauma Questionnaire (HTQ)) and secondary outcome measures were depression and anxiety symptoms (Hopkins Symptom Checklist-25 (HSCL-25), Hamilton Depression and Anxiety rating scales (HAM-D, HAM-A)), somatisation (somatisation items of SCL-90 (SI-SCL-90)), quality of life (WHO-5-Well-being Index (WHO-5)) and functioning (Sheehan Disability Scale (SDS), Global Assessment of Functioning (GAF-F, GAF-S)).
The groups evidenced similar symptom severity (SANS for negative symptoms, BPRS for positive and depression/anxiety symptoms) and psychosocial functioning (SOFAS, GAF, QLS) at baseline and follow-up as well as similar prevalence of non-psychotic disorders at follow-up.
