Mechanisms Of Change in Adolescent Pain Self-management

Study Overview
=================
Brief Summary
-----------------
The MOCAS Study aims to describe the mechanisms through which sleep deficiency affects youth responses to an online pain self-management intervention over a 6-month period. The study is a single arm trial with repeated measurements using surveys, daily diaries, and actigraphic monitoring.

Detailed Description
-----------------
The study objective is to characterize how sleep deficiency influences youth's ability to engage with, implement, and benefit from pain self-management intervention. The investigators will recruit a cohort of 80 youth, ages 12 to 17 years, with chronic musculoskeletal, head, or abdominal pain into a single arm trial conducted at one site. Assessments will occur at baseline, immediately after intervention, and repeated at 3 months post-intervention. Mediators will be assessed at mid-treatment (4 weeks). All youth will receive an 8-week internet-delivered pain self-management intervention (WebMAP). Following the recommended Common Data Elements for self-management three self-management processes are measured including patient activation, pain self-efficacy, and self-management skills, and patient-reported outcomes of health (global health, fatigue) and pain (pain symptoms, pain-related disability). Positive and negative affect and executive function are assessed as potential mediators. Sleep deficiency is comprehensively assessed with subjective measures, daily sleep logs, and ambulatory actigraphy monitoring to measure disrupted sleep, amount of sleep, sleep quality, and insomnia symptoms.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Web-based CBT (Web-MAP)<br>The eight child modules include: 1) education about chronic pain, 2) recognizing stress and negative emotions, 3) deep breathing and relaxation, 4) implementing coping skills at school, 5) cognitive skills (e.g., reducing negative thoughts), 6) lifestyle interventions, 7) staying active (e.g., pleasant activity scheduling), 8) relapse prevention. The eight parent modules are: 1) education about chronic pain, 2) recognizing stress and negative emotions, 3) operant strategies I (using attention and praise to increase coping), 4) operant strategies II (using rewards to increase positive coping and reach school goals), 5) modeling, 6) lifestyle, 7) communication, 8) relapse prevention. | Behavioral: Web-based CBT (Web-MAP)<br>* see arm description<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain Intensity Ratings | Pain intensity will be measured using the 11-point Numerical Rating Scale (NRS) completed by children via daily diary assessments over a 7-day period. Scores range from 0 = no pain to 10 = worst pain imaginable. Scores are averaged at each timeframe with higher scores indicating higher pain intensity. | Baseline, 12 weeks (post-treatment), 6 months (follow-up) | 
| Pain-related Disability | The Child Activity Limitations Interview (CALI-9) is a daily diary validated to assess perceived difficulty in completing 9 daily activities as a measure of pain-related disability. Responses are rated on a 5-point scale (0-4), summed, and transformed to a 0-100 scale, with higher scores indicating greater perceived difficulty with activities. Youth will provide ratings daily for 7 days on their online diaries at each assessment period. Mean total activity limitations across the reporting period is used in analyses, with higher scores indicating greater disability. | Baseline, 12 weeks (post-treatment), 6 months (follow-up) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Fatigue | Children will complete ratings of fatigue on the PedsQL Multidimensional Fatigue Scale, which yields three scores for general fatigue, cognitive fatigue, and sleep-rest fatigue. Scores range from 0-100, where higher scores indicate fewer problems with fatigue. It has been widely used in many pediatric chronic health conditions demonstrating strong reliability and validity. | Baseline, 12 weeks (post-treatment), 6 months (follow-up) | 
| Global Health | Global health will be assessed by child self report with the PROMIS pediatric global health scale, a 7-item measure summarizing a child's physical, mental, and social health into a single score. The seven items are rated on a 1-5 scale based on their frequency over the past week. Raw scores are then transformed to a T-Score metric allowing for comparisons to a general (norm) population with mean of 50 and standard deviation of 10. Higher scores mean that the child's global health is more positive. | Baseline, 12 weeks (post-treatment), 6 months (follow-up) | 
| Number of Treatment Modules Completed | Measured as the number of pain self-management modules completed by each participant during the intervention period ranging from 0 to 8 modules. Module completion was categorized as no exposure with 0 modules completed vs some exposure with 1-8 modules completed. Module usage information is obtained from the administrative database of the internet program and is stored in real time. | 12 weeks (post-treatment) | 
| Treatment Acceptability | Measured using the Treatment Evaluation Inventory (TEI) completed via teen report, which includes 9 items that are rated on a 5 point likert scale (1-5) where higher scores indicate greater treatment acceptability. Individual scores are summed for a total ranging from 9 to 45, and scores over 37 indicate moderate treatment acceptability. | 12 weeks (post-treatment) |
