Brief summary
We are investigating the effects of a mind-body based mobile application on the experience of chronic pain. Participants meeting our criteria for chronic pain (confirmed via self-report) will complete an online baseline questionnaire. Eligible participants will be enrolled in the study and randomized into control (usual care, waitlisted) or intervention group (6-week mind-body based mobile application intervention). Randomization will be stratified by pain intensity and gender using computer-generated block randomization to create varying block sizes of 4 and 8. We will run the trial in multiple cohorts in series to obtain desired sample size. All participants will complete online questionnaires at baseline and post-intervention at 6 weeks that measure pain intensity, interference with daily living, pain perceptions, mental health outcomes, and medication use. Participants will also complete weekly questionnaires on weeks 2 to 6 to gauge frequency of application usage (intervention) or other pain treatments (control). Participants in the intervention group will be asked to repeat the follow-up questionnaire at 12-weeks.
Detailed description
See protocol for more details. (submitted at time of registration)
Interventions
Self-directed; Study team will recommend daily use of mobile app for 6 weeks with a minimum of 4 times/week usage of mobile app for 6 weeks. Frequency will be monitored via weekly surveys.

Study design
Masking description
Participants in the control group will be aware that they have are serving as controls that have been wait-listed for access to the mobile application.
Intervention model description
Participants will be randomized into one of two groups: control (usual care, waitlisted) or intervention group (6-week mind-body mobile application use). Randomization will be stratified on pain intensity and gender using computer generated block randomization to create varying block sizes of 4 and 8.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Brief Pain Inventory-short Form (BPI-SF) | Baseline, 6 weeks | Primary outcome of Pain Severity: Single item scale within larger Brief Pain Inventory tool. Item scale ranges from 0 to 10. 0 = no pain, 10 = pain as bad as you can imagine. Higher scores indicate worse outcome, lower scores indicate better outcome. Item range = (0,10). Primary outcome of Pain Interference: Item 9 on BPI measures interference with daily living. There are 7 items embedded within and each is scored on 11-point scales from 0 = does not interfere to 10 = completely interferes for interference with activities of daily living. Pain interference score is calculated as an average of the 7 items, with a range from 0 to 10. Higher scores represent worse outcomes. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient Reported Outcome Measurement Information System (PROMIS) Short Form 8a Pain Interference | baseline, 6 weeks | Measures self reported pain interference in daily activities (over 7 days). 8 items are added together for a sum score. Each item uses 5-pt Likert scale from 1 = not at all to 5 = very much (regarding pain interference). Scale range = 8 to 40. Higher scores indicate worse outcomes. |
| Pain Catastrophizing Questionnaire (PCS) | baseline, 6 weeks | Measures thoughts and perceptions of pain, 13 items, scored using 5-pt Likert scale 0 = not at all to 4 = all the time. Scores are the sum of all items. min score = 0; max score = 52. Higher scores indicate worse outcomes. |
| DASS-21 (Depression, Anxiety, and Stress Scale) | baseline, 6 weeks | Measures self reported emotional states, three subscales: depression, anxiety, stress (each 7 items) Items scored on 4-point Likert scale: 0 = did not apply to me at all to 3 = applied to me very much or most of the time. Scores for each subscale are summed. Scores are then multiplied by 2 to calculate final score for each subscale. Scale ranges for each subscale is from 0 to 42 (after doubling of scores). Higher scores indicate worse outcomes. |
| Quality of Life Short Form 12 (SF-12) Physical (PCS-12) and Mental (MCS-12) Component Summary Scores (Z-scores; Normalized Based on US General Population) | baseline, 6 weeks | Measures self-reported impact of health on daily life. The SF-12 is a brief version of the longer SF-36 and contains 12 items measured using a variety of Likert scales and dichotomous yes/no scales, with each item response assigned a numerical weight. PCS and MCS are component z-scores that are calculated using regression weights and constants for each (mental and physical) which have been derived from a U.S. population. Each item response choice category is coded as an indicator variable (scored 1 / 0). Indicator variables are weighted using regression coefficients from the US population for the MCS and PCS. The weighted scores across all items are then summed and are added to a constant (regression intercept) to obtain summary scores. Score ranges 0 to 100. Normalized score such that component scales have a mean of 50 and standard deviation of 10 in the general population. Lower scores indicate worse outcomes. Higher scores indicate better |

We have only reported frequencies of use (generally), and omitted details regarding dosage and number of pills as it was decided that this was beyond the scope of our team and trial. We also did not compare baseline to 6 weeks for the same reason. |
| PROMIS Pain Interference Short Form 8a | 12 weeks | Measures self reported pain interference in daily activities (over 7 days). 8 items are added together for a sum score. Each item uses 5-pt Likert scale from 1 = not at all to 5 = very much (regarding pain interference). Scale range = 8 to 40. Higher scores indicate worse outcomes. |

Measures self-reported impact of health on daily life. The SF-12 is a brief version of the longer SF-36 and contains 12 items measured using a variety of Likert scales and dichotomous yes/no scales, with each item response assigned a numerical weight. PCS and MCS are component z-scores that are calculated using regression weights and constants for each (mental and physical) which have been derived from a U.S. population.

Quality of Life Short Form 12 (SF-12) Physical (PCS-12) and Mental (MCS-12) Component Summary Scores (Z-scores; Normalized Based on US General Population)
Measures self-reported impact of health on daily life. The SF-12 is a brief version of the longer SF-36 and contains 12 items measured using a variety of Likert scales and dichotomous yes/no scales, with each item response assigned a numerical weight. PCS and MCS are component z-scores that are calculated using regression weights and constants for each (mental and physical) which have been derived from a U.S. population. Each item response choice category is coded as an indicator variable (scored 1 / 0). Indicator variables are weighted using regression coefficients from the US population for the MCS and PCS. The weighted scores across all items are then summed and are added to a constant (regression intercept) to obtain summary scores. Score ranges 0 to 100. Normalized score such that component scales have a mean of 50 and standard deviation of 10 in the general population. Lower scores indicate worse outcomes. Higher scores indicate better
Time frame: baseline, 6 weeks
Population: Missing Physical Component Score data for three participants in the control group.~Missing Mental Component Score data for three participants in the control group.
