A comparative study of comorbidities, symptom profiles, and childhood trauma in PTSD and non-PTSD trauma patients at Oslo University Hospital.

To explore the differences in mental health symptom profiles, trauma profiles, childhood trauma and comorbidities in patients with PTSD and those without PTSD. A cross-sectional study was carried out on 110 adult patients with trauma backgrounds attending a mental health outpatient clinic in Southern Oslo, Norway. In addition to self- report questionnaires, several standardized validated diagnostic tools were used to assess mental disorders. Multiple linear regression models were used to assess the association between trauma history, the mental health symptom profile of the patients, and PTSD diagnosis. Bivariate logistic regression was used to examine if childhood trauma/adversities were associated with PTSD. Patients diagnosed with PTSD had significantly higher rates of comorbid major depressive disorder, panic disorder, agoraphobia disorder, and social phobia compared to those without PTSD. We also found a positive association between PTSD diagnosis and all the different mental health symptoms domains of the Symptom Checklist-90-Revised instrument. When adjusted for age, gender, education, smoking habits, immigration, relationship, and employment status, these associations persisted with varying effects. We did not find any association between PTSD and childhood trauma/adversities, however, sexual abuse trended towards an association. Adult trauma patients with PTSD may have more comorbid disorders and mental health symptoms. Childhood trauma may be less critical for the PTSD diagnosis in this group. In clinical practice, personalized treatment plans addressing both the symptom burden and its comorbidities may be beneficial.
