SERENITY Study of Chronic Pain Interference in Adults (SERENITY)

9 de setembro de 2026 atualizado por: University of Minnesota

Modeling of Inter-Individual Differences in Chronic Pain Using Holistic Measures of Pain Severity, Stress, Cognition, Body and Mind Awareness

SERENITY is a remote observational study designed to characterize inter-individual differences in chronic pain among adults with chronic low back pain and adults with spinal cord injury-related neuropathic pain.

Participants will complete baseline assessments and intensive longitudinal data collection using ecological momentary assessment surveys, brief cognitive tests, and passive Fitbit data collection. Ecological momentary assessment surveys will be completed 4 times per day for at least 3 weeks and will assess pain interference, pain intensity, stress, affect, sleep, body and mind awareness, agency, medication use, manual therapy frequency, and related factors.

The study will use Bayesian hierarchical modeling, clustering analyses, and causal discovery approaches to identify person-specific and group-level factors associated with pain interference.

Descrição detalhada

Chronic pain is heterogeneous, and individuals with similar pain diagnoses may experience different levels of pain interference and may have different factors contributing to pain-related disability. SERENITY is a remote observational study designed to characterize between-subject heterogeneity in adults with chronic low back pain and adults with spinal cord injury-related neuropathic pain.

The study will enroll 200 adults with chronic low back pain and 200 adults with spinal cord injury-related neuropathic pain. Participants will complete baseline demographic, clinical, pain, emotional functioning, physical functioning, and quality-of-life assessments. Participants will also complete ecological momentary assessment surveys 4 times per day for at least 3 weeks. These surveys will assess pain intensity, pain interference with function, positive and negative affect, stress, sleep, body and mind awareness, agency or perceived control over pain and life, medication dosage, manual therapy frequency, and brief cognitive test performance.

Fitbit data will be collected passively during the study period to measure sleep, physical activity, heart rate, heart rate variability, daily readiness, and stress management. The study will use intensive longitudinal data from ecological momentary assessment surveys and Fitbit measures to develop Bayesian hierarchical models, pain-profile clusters, and personal causal models.

The primary objective is to identify SERENITY measures associated with or causally related to pain interference within each pain group. The study will also examine heterogeneity in pain profiles and explore person-specific causal relationships between pain interference and measures of pain severity, stress, cognition, body and mind awareness, affect, and agency.

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Pain Interference With Function
Prazo: Four times daily for at least 3 weeks

Pain interference with function will be assessed using a single ecological momentary assessment item: "How much is your low back pain/neuropathic pain affecting your daily life function?" Response options range from 0 to 4, with higher scores indicating worse pain interference with function. This is not a standardized scale and is administered via ecological momentary assessment to support causal discovery pathways.
