[Posttraumatic disorders in patients with schizophrenia spectrum disorders]

Area of Science:

• Psychiatry
• Trauma Studies
• Clinical Psychology

Context:

• International studies indicate high prevalence of interpersonal violence and PTSD in schizophrenia spectrum disorders.
• Limited research exists on these comorbidities within German-speaking regions.
• This study addresses the gap by investigating a German inpatient population.

Purpose:

• To determine the prevalence of lifetime interpersonal violence experiences.
• To assess the rate of comorbid posttraumatic stress disorder (PTSD) in inpatients with schizophrenia spectrum disorders.
• To provide data from a German university hospital setting.

Summary:

• 145 inpatients with schizophrenia spectrum disorders were assessed using the Structured Trauma Interview (STI) and the Structured Clinical Interview for DSM-IV (SCID).
• Two-thirds (66%) reported lifetime interpersonal violence, including sexual and physical abuse.
• The prevalence of acute PTSD was 12%, with an additional 9% experiencing subsyndromal PTSD.

Impact:

• Confirms high rates of violence exposure and PTSD comorbidity in German schizophrenia patients.
• Highlights the need for routine screening for violence and PTSD in this population.
• Emphasizes the integration of trauma-specific therapies into treatment protocols for schizophrenia spectrum disorders.
