Changes in Functional Magnetic Resonance Imaging (fMRI) |
fMRI analysis looks at alterations in brain activity from baseline at rest and in response to pain cues |
Participants will undergo an fMRI session at the beginning (Week 1) to establish a baseline and a follow up end of the study (Week 8). |
|
Secondary |
Change in Nocturnal Heart Rate as measured by OURA Ring |
Heart rate (beats per minute) will be quantified throughout the night via the OURA ring. |
Daily from baseline through study completion at 8 weeks |
|
Secondary |
Change in daily self-report measures for task load |
End of Day Questionnaire (EoD)-Developed at the Rockefeller Neuroscience Institute (RNI) as a modification of the NASA Task Load Index. There are 5 Likert scales to assess workload (0=very low and 100=very high), as well as 4 follow up questions. This questionnaire addresses subjective measures of workload and stressors that were encountered throughout the day. |
Daily from baseline through study completion at 8 weeks |
|
Secondary |
Change in per session self-report measures |
State-Trait Anxiety Index (STAI) - Commonly used measure of state and trait anxiety, and done with 20 very brief questions. Values range from 20 to 80, with higher scores representing more severe anxiety. Participants will complete the STAI questionnaire before and after each session, twice a week. |
Before and after each float session (Weeks 2-7) |
|
Secondary |
Change in testing battery self-report measures in personality |
Big Five Inventory (BFI)-44 item inventory designed to measure the Big Five Factors of personality on a 5-point Likert Scale. Higher scores indicate a higher tendency for that personality trait (1=disagree strongly to 5=agree strongly). |
Beginning and end of the investigation (Week 1 & Week 8) |
|
Secondary |
Change in testing battery self-report measures in emotional regulation |
Emotion Regulation Questionnaire (ERQ)-10-item scale designed to measure tendency to regulate emotions. Each item is answered on a 7-point Likert Scale (1=strongly disagree to 7=strongly agree). Higher scores indicate a higher emotion regulation strategy. |
Beginning and end of the investigation (Week 1 & Week 8) |
|
Secondary |
Change in testing battery self-report measures in mindfulness |
Five Facet Mindfulness Questionnaire (FFMQ)-39 item inventory assesses the five facets of mindfulness on a 5-point Likert Scale (1=never or very rarely true and 5=very often or always true). Each facet is tallied and the sum total responses are divided by 39 (number of items). Higher scores indicate higher levels of mindfulness. |
Beginning and end of the investigation (Week 1 & Week 8) |
|
Secondary |
Change in testing battery self-report measures in sleep quality |
Pittsburgh Sleep Quality Index (PSQI)- 19 item inventory with 7 subjective components that assess sleep quality over time. Each component is scored from 0 to 3 (0=very good and 3=very bad). The sum of the components is the global score and ranges 0-21 (0=no difficulty and 21=severe difficulties). The higher the global score, the poorer the sleep quality. |
Beginning and end of the investigation (Week 1 & Week 8) |
|
Secondary |
Cold Pressor Stressor |
The cold pressor is a water bath with its temperature maintained at 3C. The participant is asked to submerge a hand in the water bath. The water is cold enough to be a painful stimuli but not so cold as to cause tissue damage. The participant rates their pain level on a standard Wong-Baker pain scale prior and immediately after voluntary withdraw from the cold pressor. The Wong Baker pain scale asks the participant to rate their pain on a scale of 0-10 with 0= no pain and 10= the most pain. Duration of time spent in the water is also recorded. |
The participant will undergo the cold pressor test at the beginning (Week 1) and end of the study (Week 8) with the option for an additional session after a few sessions at the investigators discretion. |
|
Secondary |
Serum Analysis for changes in Interleukin 1B concentration |
Blood samples will be collected through out the study and analyzed for a key stress indicators Interleukin 1B. |
Beginning (Week 1), middle (Week 5), and end of the investigation (Week 8) |
|
Secondary |
Serum Analysis for changes in Interleukin 6 concentration |
Blood samples will be collected through out the study and analyzed for a key stress indicators Interleukin 6. |
Beginning (Week 1), middle (Week 5), and end of the investigation (Week 8) |
|
Secondary |
Serum Analysis for changes in Cortisol concentration |
Blood samples will be collected through out the study and analyzed for a key stress indicator Cortisol. |
Beginning (Week 1), middle (Week 5), and end of the investigation (Week 8) |
|
Secondary |
Changes in Serum Analysis for changes in Dehydroepiandrosterone concentration |
Blood samples will be collected through out the study and analyzed for a key stress indicator Dehydroepiandrosterone. |
Beginning (Week 1), middle (Week 5), and end of the investigation (Week 8) |
