Complex-Posttraumatic Stress Disorder - Cultural Adaptation of a Therapeutic Manual and Development of a Culture-specific Diagnostic Module for Refugee Populations in Switzerland (Pilot Trial)
In January 2022, the World Health Organization (WHO) launched the 11th edition of the International Classification of Diseases (ICD-11). This diagnostic manual includes the new diagnosis of complex post-traumatic stress disorder (CPTSD). This new diagnostic category describes difficulties that may arise as a result of multiple, prolonged or repeated trauma, from which it is difficult or impossible to escape, such as torture, domestic violence or childhood sexual abuse. People affected by CPTSD often have difficulty regulating their emotions and maintaining relationships with others, and they often show a negative self-concept.
Evidence from the field of cultural clinical psychology indicates cultural variation in the CPTSD symptoms across different cultural groups. In addition, psychopathology is shaped by structural factors such as inequality and/or discrimination.
This research project aims to highlight such cultural and structural aspects related to PTSD and CPTSD among refugee populations in Switzerland. A diagnostic interview and a therapeutic manual will be culturally adapted and pilot tested with a small sample (n = 24).

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Feasibility ESTAIR manual
Time Frame: 7 months
|
Feasibility of the ESTAIR manual will be evaluated via the percentage of users who who adhere to the therapy until the end (out of those who start the therapy).
As general rule, 80-90% adherence is considered as excellent, 70-80% as satisfactory, and 60-70% as acceptable.
|
7 months
|
Feasibility International Trauma Interview (ITI)
Time Frame: 1 month
|
Feasibility will be examined based on the percentage of participants who complete the ITI.
As general rule, 80-90% participation and adherence is considered as excellent, 70-80% as satisfactory, and 60-70% as acceptable.

Feasibility research procedures
Time Frame: 7 months
|
Feasibility will be evaluated based on the percentage of participants who give their informed consent (out of those invited) and based on the percentage of participants who adhere to the study until the end (out of those who sign the informed consent).
As general rule, 80-90% participation and adherence is considered as excellent, 70-80% as satisfactory, and 60-70% as acceptable.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Complex post-traumatic stress disorder
Time Frame: 7 months
|
International Trauma Interview.
This interview evaluates 12 symptoms (6 for post-traumatic stress disorder and another 6 for disturbances in self-organisation).
A diagnosis of complex post-traumatic stress disorder requires that the post-traumatic stress disorder criteria are satisfied (with a diminished startle response if hypervigilance or exaggerated startle are not present), and the endorsement of one of two symptoms from each of the three "disturbances in self-organisation" symptom clusters, plus endorsement of functional impairment associated with these symptoms.
Endorsement of a symptom requires that it is trauma related, has been present for at least a year and scores > 2.
|
7 months
|
Depression
Time Frame: 7 months
|
Patient Health Questionnaire (PHQ-9).
The PHQ-9 score may range from 0 to 27, since each of the 9 items can be scored from 0 (not at all) to 3 (nearly every day).
Higher scores mean higher levels of depression.
|
7 months
|
Anxiety
Time Frame: 7 months
|
General Anxiety Disorder Questionnaire (GAD-7).
The GAD-7 score may range from 0 to 21, since each of the 7 items can be scored from 0 (not at all) to 3 (nearly every day).
Higher scores mean higher levels of anxiety.
|
7 months
|
Somatic Symptoms
Time Frame: 7 months
|
Somatic Symptoms Scale (SSS-8).
The SSS-8 score may range from 0 to 32, since each of the 8 items can be scored from 0 (not at all) to 4 (severely).
Higher scores mean higher levels of anxiety.
|
7 months
|
Wellbeing
Time Frame: 7 Months
|
WHO-5 questionnaire.
Scores range from 0-25, with higher scores reflecting higher levels of well-being
