Measuring Chronic Pain Impact: Measurement Enhancement for Chronic Pain
NCT04426812 · View on ClinicalTrials.gov ↗
Study Summary
Many complementary and integrative health approaches have been shown to be effective for chronic pain and included in guidelines. This evidence of effectiveness is built on hundreds of studies representing millions of research dollars, and the ability to analyze and better compare results across these studies is essential to obtain the full value of this investment. However, useful across-study comparisons which would allow better understanding and targeting of these interventions are hampered by at least two challenges: the lack of common outcome measures and the inability to meaningfully stratify or classify patients. The first two Aims of this study each address one of these two challenges. The last Aim takes advantage of this study to further test the viability of MTurk as a data collection platform. Specific Aim 1 addresses the lack of common outcome measures. This Aim is to develop and evaluate links or crosswalks between the PROMIS-29 and other common (legacy) measures used for chronic pain so that the results of studies using different measures can be compared. Our hypothesis here is that we will be able to create some sort of linkage between PROMIS and legacy measures that will allow for each pair estimates of one to be made from the other. Specific Aim 2 addresses the inability to meaningfully stratify or subclassify chronic pain patients. This Aim is to evaluate and refine the chronic pain impact stratification scheme (ISS) proposes by the NIH Research Task Force on chronic low back pain, which is based on 9 PROMIS-29 items. Our hypothesis here is that the ISS can be refined so that it can identify subgroups of chronic pain patients with different levels of morbidity and different needs for treatment. Specific Aim 3 addresses the potential for more efficient data collection using the MTurk platform. This Aim is to evaluate MTurk as a cost- and time-efficient method to collect quality data on individuals with chronic pain. Our hypothesis here is that w

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04426812
The ClinicalTrials.gov registry entry for NCT04426812 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 11,146 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is RAND, which has 57 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Chronic Pain appearing as the primary indexed condition, and to 1 intervention — of which No intervention; just data collection is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04426812 reports 1 study location spanning 1 distinct geographic area — top geographies include California. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
