Breathwork Intervention for Posttraumatic Stress

The PCL-5 is a 20-item self-report measure. It is scored by summing the ratings for each of the 20 items. Each item is rated on a 5-point scale (0-4), where 0 means "Not at all" and 4 means "Extremely". The total score, ranging from 0 to 80, represents the severity of PTSD symptoms.

The BTQ is a 10-item instrument that lists a number of difficult of stressful things that sometimes happen to people. The Brief Trauma Questionnaire (BTQ) is scored by counting the number of traumatic events experienced that meet DSM-IV "Criterion A" criteria (life threat or serious injury). Each of the 10 items on the BTQ is scored as positive if the respondent reports experiencing the event and also reports either life threat or serious injury (depending on the specific question). A higher score indicates a greater number of traumatic events experienced

Posttraumatic growth will be assessed with the 21-item Posttraumatic Growth Inventory (PGI). It is scored by summing responses to its 21 items, each rated on a 6-point Likert scale. The total score ranges from 0 to 105, with higher scores indicating greater perceived post-traumatic growth. Scores on the five subscales (Relating to Others, New Possibilities, Personal Strength, Spiritual Change, and Appreciation of Life) are calculated by averaging the relevant items within each subscale.

The Patient Health Questionnaire 2-item (PHQ-2) is scored by summing the responses to its two questions. Each question offers four possible responses, scored from 0 to 3, with 0 being "not at all" and 3 being "nearly every day". A total score is calculated by adding the scores of both questions, resulting in a range from 0 to 6. A score of 3 or higher suggests further evaluation for depression

Patients will note their anxiety with the Generalized Anxiety Disorder-2 (GAD-2). This 2-item scale is scored by summing the responses to two questions, each rated on a 4-point scale. The possible scores for each item range from 0 to 3, with 0 representing "Not at all" and 3 representing "Nearly every day". The total score, which ranges from 0 to 6, is then calculated by adding the scores of the two items. A higher score indicates a greater likelihood of anxiety.

Participants will be asked about their pain intensity and pain interference with the Pain, Enjoyment of Life and General Activity (PEG) Scale. The 11-item Likert scale is scored by averaging the responses to three questions, each rated on a scale of 0 to 10. A higher score indicates a greater impact of pain.

The PROMIS Sleep Disturbance 6a and Sleep Duration measures are scored by first summing the responses to the individual items, then converting the raw sum score to a standardized T-score using conversion tables. The PROMIS Sleep Disturbance 6a uses a 5-point Likert scale for each item, and the Sleep Duration is a separate item with its own scoring. The T-score represents the individual's sleep disturbance relative to a reference population (mean of 50, standard deviation of 10).

The PROMIS v1.0 Alcohol Use - Short Form 7a is a 7-item questionnaire using a 5-point Likert scale (1- never to 5- almost always). It is scored by summing the responses to each question, where each question has a 5-point Likert scale. Higher scores indicate stronger positive expectancies about alcohol use. The raw score is then converted to a T-score for comparison with a normative sample.

The Smoking: Nicotine Dependence for All Smokers - Short Form 4a is a 4-item questionnaire using a 5-point Likert scale (1-never, 5-always). The Smoking: Nicotine Dependence for All Smokers - Short Form 4a is scored by summing the values of the responses to each of its four items. Each item has five possible response options, ranging from 1 to 5, with higher scores indicating greater nicotine dependence. The total raw score ranges from 4 (lowest dependence) to 20 (highest dependence).

The PGIC is a single-item, seven-point scale used to assess a patient's perception of change in their condition since a specific point in time. The scale ranges from "very much worse" to "very much improved". Higher scores indicate greater improvement, while lower scores indicate worsening or no change.

Participants will complete the 3-item, state version of the Nondual Awareness Dimensional Assessment. The NADA is scored 0-10 and responses are averaged across the 3-items. A higher score is indicative of a greater self-transcendent state.

The Emotional Breakthrough Inventory is a 6-item questionnaire to assess emotional breakthrough resulting from an experience. It is scored 0-10 and scores are summed, with a higher score being indicative of a greater emotional breakthrough.

The Perceived Body Boundary Scale is a single visual item used to assess the strength of the boundary between the self and the world using a 7-point Likert type scale (1=Weak boundary, 7=Strong boundary).

The single-item Spatial Frame of Reference Continuum describes a spectrum of ways individuals and organisms represent and interact with spatial information, ranging from response A (self-centered (egocentric)) to response G (world-centered (allocentric) perspectives). Response G indicates the highest level of world-centered perspective.

The Inclusion of Other in Self (IOS) is a single-item scale. It is scored by having the respondent select one of seven pairs of overlapping circles that best represents their relationship with another person or group. Each pair of circles represents a different level of overlap, from completely separate (1) to almost completely overlapping (7). The chosen number (1-7) serves as the score, indicating the degree of perceived closeness and interconnectedness.

The 13-item Nondual Awareness Dimensional Assessment-Trait (NADA-T) will be used to assess traits of consciousness. The Nondual Awareness Dimensional Assessment-Trait (NADA-T) is scored by summing responses to 13 items, each on a 5-point Likert scale, ranging from "never or very rarely" to "very often or always". The scale assesses two dimensions of nondual awareness: self-transcendence and bliss. The total score can range from 13 to 65, with higher scores indicating a greater experience of nondual awareness.

The Integration Engagement Scale is a 12-item questionnaire used to measure positive behavioral engagement with integration. Participants are asked to rate their experiences on a 5-point Likert scale (0 = not at all to 4 = extremely). The IES yields a total score, typically ranging from 0 to 60. Higher scores on the IES generally indicate increased positive behavioral engagement with integration.

The Experienced Integration Scale is a 12-item questionnaire to capture internal aspects of feeling integrated. Participants are asked to rate their experiences on a 5-point Likert scale (1- strongly disagree to 5=strongly agree). Items are summed; a higher score indicates greater feelings of integration.

The Whole Person Health Index (WPHI) is a 9-item survey. It is scored by The WPHI can be calculated by summing the nine response scores, such that, over time, for example, an individual's WPHI going from 45 to 25 would indicate an improvement in overall self-assessed health

Psychosocial functioning will be assessed using the Brief Inventory of Psychosocial Functioning (B-IPF), a validated 7-item self-report instrument designed to measure psychosocial impairment across key life domains. Each item is rated on a 7-point Likert scale ranging from 0 ("Not at all") to 6 ("Very much"), with higher scores indicating greater psychosocial impairment. The total score is calculated by summing responses across all items, yielding a possible range of 0 to 42.

State optimism will be assessed using a single item adapted from the State Optimism Measure: "Right now, to what extent are you feeling… optimistic about life's challenges?" Participants respond using a 7-point Likert scale ranging from 0 ("Not at all") to 6 ("Extremely"), with higher scores indicating greater state optimism.

State relaxation will be measured using a single item adapted from the Relaxation State Questionnaire: "Right now, to what extent are you feeling… refreshed and awake?" Participants respond using a 7-point Likert scale ranging from 0 ("Not at all") to 6 ("Extremely"), with higher scores indicating greater relaxation or alertness.
