Deployment of an Activity Monitoring Program to Complement a Clinical Intervention for Veterans With Gulf War Illness: Qualitative Study.
Article in JMIR human factors, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMany veterans who served in the Gulf experience Gulf War Illness (GWI), a chronic multisymptom condition associated with fatigue, pain, gastrointestinal problems and respiratory issues, mood/cognitive issues, and sleep difficulties. These symptoms contribute to decreased function, increased mental health needs, and poor quality of life. The Veterans Affairs War Related Illness and Injury Study Center in New Jersey developed a 26-week virtual health coaching intervention to support symptom management for veterans with GWI. In 2023, a consumer-grade smartwatch was added as part of an activity monitoring program to complement this program.
objectiveThe purpose of this project was to assess the feasibility and acceptability of including a smartwatch-based activity monitoring component to complement a virtual health coaching program for veterans with GWI.
methodsTwenty-four veterans enrolled in the health coaching program were invited to participate in the activity monitoring component. Participants attended a virtual orientation to set up the smartwatch, and verbal consent to share data through a Health Insurance Portability and Accountability Act (HIPAA)-compliant platform was obtained. Program feasibility was assessed by evaluating wear-time percentage and duration of use. Acceptability was assessed using two items from a monthly survey and through a midprogram semistructured interview. Quantitative data were summarized descriptively, and qualitative data were analyzed using a coding scheme adapted from Sekhon et al's Theoretical Framework for Acceptability (TFA).
resultsTwenty veterans agreed to participate in the program (mean age 49 years; 7/20, 35% female; 19/20, 94% non-Hispanic White; 11/20, 55% first-time smartwatch users). Twelve participants (60%) wore the watch for the full 26 weeks. Among participants who completed 26 weeks, median daily wear-time completeness exceeded 80% for 25 weeks. Most participants (12/20, 60%) reported that wearing the smartwatch helped them achieve their wellness goals, and the majority (16/20, 80%) said they would recommend using the smartwatch for activity monitoring to other veterans. Qualitative findings supported acceptability across TFA domains. One adverse event was reported (minor skin irritation that resolved after changing the smartwatch band to a hypoallergenic watch band).
conclusionsWithin this clinical program, pairing a smartwatch with virtual health coaching for veterans with GWI was feasible and acceptable. Activity monitoring integrated into an existing intervention may support symptom self-management and augment patient education and engagement. As no prior activity monitoring programs specific to veterans with GWI have been described, these findings could inform future program development and implementation within this population.
