Algorithm-informed Decision-making to Advance Pain Treatment (ADAPT)

July 22, 2026 updated by: Afton Hassett, Psy.D., University of Michigan

Algorithm-informed Decision-making to Advance Pain Treatment (ADAPT Study)

Researchers are exploring how certain personal factors, such as symptoms, health history, and lifestyle, may help predict which treatments will work best for someone.

The purpose of this study is to evaluate how well a study algorithm chooses the best treatments for a patient when considering their unique pain characteristics.

Study Overview

Detailed Description

During the treatment stages participants may be placed into the following interventions:

  1. Physical Therapy & Exercise -10, standardized sessions over 8 weeks delivered individually and in-person by a physical therapist
  2. Duloxetine - FDA approved for musculoskeletal pain, self-administered SNRI medication taken daily over 8 weeks.
  3. Acupressure- a mobile health program- self-administered mHealth program with daily practice over 8 weeks.
  4. PRISM- cognitive-behavioral therapy plus resilience training- 8, weekly, digitally delivered pain self-management modules with corresponding weekly 15-minute standardized telehealth coaching sessions.

After participants are placed in an initial assignment based on a combination of the use of the phenotype based algorithm and randomization, they have the option of continuing on that treatment, switching to another (to be assigned by another randomization combined with use of the algorithm) or adding a second treatment to the first (to be assigned by another randomization combined with use of the algorithm).

Analysis of results will not be a function of the arms listed here, but on whether those allocations were based on the algorithm assigning them initially to their presumed "most effective" treatment; or to a potentially less effective treatment (2nd, 3rd or 4th, choice). These "ranked phenotypic" assignments are masked from participants and researchers until after the trial is completed.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Pain, Enjoyment and General Activity (PEG) scores
Time Frame: T2 (approximately week 6) - T3 (approximately week 15)
The PEG is a three-item survey measure used to assess pain by asking for ratings of Pain intensity, Enjoyment of life, and General activity on a scale of 0-10 over the past week. The final score is the average of the three ratings, with higher scores indicating greater pain severity or interference.
T2 (approximately week 6) - T3 (approximately week 15)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference scores
Time Frame: T2 (approximately week 6) - T3 (approximately week 15)
Interference from pain is assessed using 6 items covering broad functional domains such as life enjoyment, concentration, daily activities, recreation, tasks, and socializing. The scale uses a recall period of 7 days and a response set ranging from 'Not at all" (1) to "Very much" (5). Total scores are between 4 and 20, with higher scores indicating increased pain interference.
T2 (approximately week 6) - T3 (approximately week 15)
Patient Global Impression of Pain (PGIC)
Time Frame: T3 (approximately week 15)
Overall perceived benefit of treatment will be assessed using the Patient Global Impression of Change (PGIC).34 This single-item question asks "Overall, how do you feel since the beginning of this phase of the study", and participants respond on a 1 - 7 Likert scale where 1 = markedly improved, 2 = somewhat improved, 3 = mildly improved, 4 = the same, and 5 - 7 are correspondingly "worsened".
T3 (approximately week 15)
Change in ecological momentary assessment (EMA)-derived mean Pain Interference
Time Frame: T2 (approximately week 6) - T3 (approximately week 15)
Real-time 7-day pain severity measure assessed using Qualtrics. In practice, participants initiate EMAs at wake, noon and bed-times. Momentary pain intensity will be assessed with the question: "What is your level of pain right now?" rated on a numerical rating scale from 0 = "no pain" to 10 = "worst pain imaginable."
T2 (approximately week 6) - T3 (approximately week 15)
Change in Oswestry Disability Index (ODI) scores
Time Frame: T2 (approximately week 6) - T3 (approximately week 15)
This 10-section scale has good internal consistency, discriminative validity, and sensitivity to change in cLBP. Respondents check the box next to each statement that describes their pain or disability
T2 (approximately week 6) - T3 (approximately week 15)
