Experimentální: Trauma Informed Heart Rate Variability Biofeedback (T-HRVB)
HRVB is a specific intervention that increases HRV by finding the optimal breathing frequency that will synchronize with HR oscillations (i.e., between 4 to 7 breaths per minute), increase the amount and intensity of HR variation while engaging in the biofeedback, and overtime improve HRV and overall functioning by activating both the vagus nerve and baroreceptor during practice.
T-HRVB is a six session flexible protocol that integrates active trauma informed psychotherapy into HRVB, as well as scaffolds breathing skills based on the needs of population and encourages the use of these skills as active coping skills (Puhalla et al., 2026).
Additionally, active psychotherapy skills are utilized throughout to bolster a sense of agency and engagement with the techniques.

Aktivní komparátor: Present Centered Therapy (PCT)
The PCT condition will be the study's control condition where veterans will engage in six sessions.
While PCT has shown some effect on improving PTSD symptoms, , it is generally a non-specific therapeutic modality where the therapist provides support and validation for the patient and encouragement towards their goal of stress reduction.
In accordance with the study, six sessions will be provided with the psychoeducation on PTSD and the homework sheet being provided in session one since an intake has already occurred with their non-research provider.

Clinician Administered PTSD Scale for DSM-5 Revised
Časové okno: The CAPS-5-R is conducted at the pre and post treatment visit, which typically will occur during the 1st week of treatment and the last. However, due to scheduling needs may occur a prior (pre) or following (post) week.
|
The CAPS-5-R is the newest version of the CAPS-5, which is a structured diagnostic interview for PTSD based on the PTSD criteria in the DSM-5.
All 20 symptoms of PTSD are assessed in relation to a patient's index event, which is then rated on a zero to ten severity scale with qualitative and quantitative indicators for each level of severity.
Throughout the assessment symptoms that are less trauma specific include a prompt to determine if the symptom is related to the index event.
The CAPS-5-R will be the studies primary outcome variable for PTSD symptom severity.
|
The CAPS-5-R is conducted at the pre and post treatment visit, which typically will occur during the 1st week of treatment and the last. However, due to scheduling needs may occur a prior (pre) or following (post) week.
|
|
Heart Rate (HR)
Časové okno: Assessed at the pre and post treatment visits, with the primary outcome being the baseline measures of the variable.
|
Heart Rate will be utilized as the study's primary measure of overall autonomic arousal.
|
Assessed at the pre and post treatment visits, with the primary outcome being the baseline measures of the variable.
|
|
Respiratory Sinus Arrythmia
Časové okno: Assessed at the pre and post treatment visits, with the primary outcome being the baseline measures of the variable.
|
To determine parasympathetic activity, the R-spike to R-spike interval will go through a Fourier transformation and the amount of power that occurs in the high frequency range (0.15-0.04 Hz) will be used as our measure of vagal mediated parasympathetic activity, also known as RSA.
|
Assessed at the pre and post treatment visits, with the primary outcome being the baseline measures of the variable.
|
|
Skin Conductance Level
Časové okno: Assessed at the pre and post treatment visits, with the primary outcome being the baseline measures of the variable.
|
Resting Skin Conductance Level may be used as proxy of sympathetic activity at rest, which is collected through a skin conductance monitor on the participants palm / fingers.
|
Assessed at the pre and post treatment visits, with the primary outcome being the baseline measures of the variable.

PTSD Symptom Checklist for the DSM-5 (PCL-5)
Časové okno: Provided at the pre and post treatment visit, which typically will occur during the 1st week of treatment and the last. However, due to scheduling needs may occur a prior (pre) or following (post) week.
|
The PCL-5 is 20-item self-report questionnaire that assesses each symptom of PTSD on a 5-point Likert Scale.
The PCL-5 will be used to assess for PTSD symptom severity
|
Provided at the pre and post treatment visit, which typically will occur during the 1st week of treatment and the last. However, due to scheduling needs may occur a prior (pre) or following (post) week.

Root Mean Square of Successive Differences (Rmssd)
Časové okno: Rmssd will be assessed at the pre and post treatment visits, with the baseline measure being a primary outcome at both timepoints.
|
Rmssd is a time-domain measure of vagal mediated parasympathetic activity that is determined by calculating the root mean square of successive differences within a heart beat to heart beat interval (R to R interval).
It is commonly used as a proxy for parasmypathetic activity or regulation.
|
Rmssd will be assessed at the pre and post treatment visits, with the baseline measure being a primary outcome at both timepoints.
|
|
Standard Deviation between Normal to Nrmal intervals (SDNN).
Časové okno: Assessed at the pre and post treatment visits, with the primary outcome being the baseline measures of the variable.
|
SDNN is a time domain HRV measure that acts as a proxy for overall autonomic nervous system activity and health, with greater levels usually indicative of greater health.
|
Assessed at the pre and post treatment visits, with the primary outcome being the baseline measures of the variable.
