What this record can show
This locally preserved record separates the registered protocol from source-reported registry results. Neither is a treatment recommendation.
Registry facts
This pilot study looks to further the current floatation-based REST literature by exploring the therapy's effectiveness within a community-based sample of adults with PTSD. This type of sample allows the study the opportunity to recruit both veteran and civilian subjects, two populations that can suffer from this clinical diagnosis and stand to benefit from this therapy. This study will: 1. Evaluate the psychological effects of floating for a clinical, community sample with PTSD. 2. Evaluate the physiological effects of floating for a clinical, community sample with PTSD. 3. Evaluate the subjective effects of floating for a clinical, community sample with PTSD.

primary outcomes
Time frame: Baseline, week 2, week 3
Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) A clinician-administered structured diagnostic interview that is considered the gold standard for assessing and diagnosing PTSD.
Time frame: Baseline, week 2, week 3
PTSD Checklist for DSM-5 The PCL-5 consists of 20 items and it takes 5 to 10 minutes to administer. Participants are instructed to answer items based on their experience of symptoms since the trauma (hospitalization) or in the last month (1 month). Each item corresponds to a symptom in the DSM-5.
Time frame: Baseline, week 2, week 3
Center for Epidemiologic Studies Depression Scale - Revised Diagnostic tool for criteria for a major depressive episode
Time frame: Baseline, week 2, week 3
Patient Health Questionnaire (PHQ-9) The PHQ-9 is a 9-Item measure for assessing the severity of depressive symptoms over the past 2 weeks. Scores of 1-4 are considered indicative of minimal depression, 5-9 mild depression, 10-14 moderate depression, 15-19 moderately severe depression, and 20-27 severe depression.
Time frame: Baseline, week 2, week 3
Perceived Stress Scale The Perceived Stress Scale is a psychological instrument used for measuring an individual's perception of stress.
Time frame: Baseline, week 2, week 3
Sheehan Disability Scale How much mental health issues have affected their daily activities: work/school, social/leisure activities, and family life/home responsibilities. Total disability scores range between 0 to 30, with scores ≥ 5 signifying impairment.

Time frame: Baseline, Week 2, week 3
Skin Conductance This will be measured using a program called "eSense". eSense (Mindfield Biosystems LLC), an ambulatory system for collecting skin conductance, or sweat gland activity. eSense samples skin conductance at 5 Hz, substantially lower than more traditional (and more expensive) laboratory systems. This will be done during the Trauma Narrative where subjects are asked to describe an event that they consider to be the most traumatic in their life including: who was there, what they were doing, where they were, how things looked, what they heard, etc.
Time frame: Baseline, Week 2, week 3
-Blood Pressure This will be measured using a blood pressure cuff. This is performed before and after each float.
Time frame: Baseline, Week 3
-Mini International Neuropsychiatric Interview - Depression (M.I.N.I. 7.0.2) The MINI is a short structured diagnostic interview designed to meet the need for a short but accurate psychiatric interview determining diagnostic criteria for 17 of the most common disorders in mental health. This version is for DSM-5 and ICD-10 diagnoses. The measure's psychometric properties of diagnostic validity and reliability have been determined to be strong

-Anxiety Sensitivity Index (ASI-3) 18-item questionnaire using a 4-point scale and total ASI scores can range from 0 to 72. A meta-analysis \[46\] found that patient groups with anxiety and depression commonly have a total ASI score above 30, and other studies have used a cutoff score ≥ 30 to recruit individuals with very high levels of anxiety sensitivity.
Time frame: Baseline
Overall Anxiety Severity and Impairment Scale A 5-item questionnaire that can be used across the different anxiety disorders as a continuous measure of anxiety severity and impairment over the past week. Each item is rated on a 5-point scale and the ratings are summed to obtain a total score ranging from 0 to 20.

Debriefing Interview Occurrence of adverse events and qualitative information about floating. How was your float today? What did you think about while floating? Did anything surprise you? Did you learn anything about yourself? Follow-up Questions At the end of your float, how did you feel about the duration? Wanted to get out before/Perfect amount of time/Wish I could have stayed longer. Other techniques tried to help relax and feel less anxious and stressed? anti-anxiety medication/psychotherapy/massage/exercise/alcohol/breathing techniques/cigarettes/marijuana/progressive muscle relaxation/meditation/yoga/other Experience during and after today's float session compared to the other relaxation techniques tired? More relaxation with others/Equally as good as the others/More relaxation with floating than any others Interested in floating again in the future and thoughts on specialized pools being effective therapy for reducing symptom severity? Yes/No/Maybe
