Brief summary
This study aims to investigate the effect of a pranayama focused yoga intervention on post-traumatic symptom severity in patients with post-traumatic stress disorder undergoing standard psychotherapy/ trauma-focused cognitive-behavioral therapy (TF-CBT). Therefore, short pranayama sessions of 5-10 minutes will be provided to the patients directly at the begin of each of standard TF-CBT unit, while the control group will get standard TF-CBT alone. It should further be investigated, whether pranayama can enhance the affective tolerance of patients with post-traumatic stress disorder towards the used exposure techniques of TF-CBT.
Interventions
BEHAVIORALPranayama assisted trauma-focused Cognitive Behavioral Therapy (TF-CBT)
The pranayama intervention is placed directly at the begin of the respective TF-CBT unit and will be repeated for 10 subsequent TF-CBT units. Pranayama contains the performance of Kapalabhati, Ujjayi, and/or Nadi Shodhana (for overall 1 minute) as well as following Kumbhaka (intentional respiratory reflex inhibition). Pranayama will be repeated 3 times before each TF-CBT unit.

Masking description
Participants and Therapists (Care Provider) could not be blinded according to the nature of the intervention. However, therapists will be blinded to allocation concealment as they do not be aware of the patients' group assignment at baseline assessment until they open the opaque randomization envelope, which contains the patient randomization number and group assignment. The random sequence generation and the envelopes were prepared by the study coordinator who is not involved patient recruitment. Patients received post intervention questionnaires from a study assistant/nurse of the respective outpatient department who is also blinded to the patients' group assignment. After completing the questionnaires, the study assistant will sent them to study coordinator so that the therapist could not influence the patients' answers.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intensity of posttraumtic symptoms | week 10 | Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5): The PCL-5 is a standard 20-item scale with a sum score ranging from 0 to 80 points. The cut-off point for clinically relevant symptom severity is 33 points. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Ability of social participation | week 10 | Patient-Reported Outcomes Measurement Information System - Ability to Participate in Social Roles and Activities Scale (PROMIS): The PROMIS-Social Participation Subscale is a standard 8-item scale ranging from 0 to 100 points with 100 points represent the highest possible ability to participate/function. |
| Anxiety | week 10 | Beck Anxiety Inventory (BAI): The BAI is a standard 21-items scale ranging from 0 to 63 points with 0-7 points = minimal anxiety, 8-15 points = mild anxiety, 16-25 points = moderate anxiety, and 26-63 points = clinically relevant anxiety. |
| Depression | week 10 | Beck Depression Inventory Revision (BDI-II): The BDI-II is a standard 21-items scale ranging from 0 to 63 points with 0-13 points =no/clinically not relevant depression/depression in remission, 14-19 points = mild depression, 20-28 points = moderate depression und 29-63 points = severe depression. |
| Distress Tolerance | week 10 | Distress Tolerance Scale (DTS): The DTS is a standard 15-item scale ranging from 0 to 75 points. Higher scores represent higher distress tolerance. |
| Emotion Regulation | week 10 | Emotion Regulation Scale (ERQ): The ERQ is a standard 10-item scale with 6 items are added to the Cognitive Reappraisal subscale ranging from 6 to 42 and 4 items are added to the Expressive Suppression subscale ranging from 4 to 28. Higher scores on the Cognitive Reappraisal subscale and lower ones on the Expressive Suppression subscale represent a better regulation of emotions. |
| Body Awareness | week 10 | Scale of Body Connection (SBC): The SBC is a standard 20-items scale ranging from 0 to 80 that contains two subscales: Body Awareness and Body Dissociation. Higher scores on Body Awareness and lower scores on Body Dissociation represent a better body awareness. |
| Breath Holding Duration | week 10 | Breath Holding Task (BHT): The BHT is standard test procedure for the measurement of ability of the suppression of the respiratory reflex. In PTSD patients, it is associated with distress tolerance. |
| Acute Emotional Stress | week 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 | Emotional Stress Reaction Questionnaire (ESRQ): The ESRQ is standard 14-items scale ranging from -21 points (predominance of negative emotions) to +21 points (predominance of positive emotions). Patients received the ESRQ before and after each CBT unit. |
| Adverse Events | week 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 | Number of patients with adverse events (and type of the adverse event) |
| Health-related quality of life | week 10 | Short Form 12 Health Survey (SF-12): The SF-12 is a standard 12-item scale with two sum scores (physical and mental quality of life) ranging from 0 to 100 points. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Treatment Expectation | week 0 | Treatment Credibility Scale (TCS): The TCS is a standard NRS scale ranging from 0 points (lowest expectation of treatment effectiveness) to 10 points (highest expectation of treatment effectiveness). |
