Trial Outcomes & Findings for Evaluation of a Mind-body Based Application for the Treatment of Chronic/Persistent Pain. (NCT NCT05090683)

NCT ID: NCT05090683

Last Updated: 2025-01-29

Results Overview

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.

Participant Flow

Three cohorts recruited in series for three study starts: Cohort 1: October 15 2021 Cohort 2: January 6 2022 Cohort 3: April 7 2022 Randomized on October 15, 2022 (1); January 6, 2022 (2); and April 7, 2022.

Participants completed a baseline questionnaire following initial interest in the study. If the participants did not meet the criteria for chronic/persistent pain based on their responses to this survey, they were automatically excluded. If participants did not complete baseline (pre-randomization) survey such that primary outcome and randomization data was incomplete, they were excluded.

PRIMARY outcome

Timeframe: Baseline, 6 weeks

Population: Intervention period was 6 weeks, and questionnaires were completed at baseline and at 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 outcome

Timeframe: 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.

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

SECONDARY outcome

Timeframe: 12 weeks

Population: Members of the intervention group who completed the additional 12 week follow up (intervention ended at 6 weeks).

Measures self reported pain severity; Pain interference (over past 24 hours) Only measured in the intervention group (as wait-listed controls had accessed the mobile app and were released from the study). BPI 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). BPI 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.

The app also includes access to podcasts that focus on pain counselling and pain education. Mind-body mobile application: 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.
Control
Participants are asked to continue with usual care for pain treatments. They are asked not to start any new forms of treatment.
PROMIS Pain Intensity Short Form
2.74 units on a scale
Standard Deviation 0.54

SECONDARY outcome

Timeframe: 6 weeks

Population: Medication categories are not mutually exclusive as many report usage of multiple classes of drugs.

Self-reported quantify of medication use (number of participant reporting regular usage). Note: this was a change from original plan for reporting. 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.

SECONDARY outcome

Timeframe: 12 weeks

Population: Members of the intervention group who completed the additional 12 week follow up (intervention ended at 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)
16.46 score on a scale
Standard Deviation 12.83

SECONDARY outcome

Timeframe: 12 weeks

Population: Members of the intervention group who completed the additional 12 week follow up (intervention ended at 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 outcomes.

SECONDARY outcome

Timeframe: 12 weeks

Population: See above 12 week data.

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.
