Chronic inflammatory rheumatic diseases (IRDs), such as rheumatoid arthritis and spondyloarthritis, can cause pain, fatigue, and mobility issues, significantly impacting patients' quality of life. Physical activity is an important part of managing these conditions, as it helps reduce pain, maintain mobility, and prevent complications. However, many patients struggle to stay active due to pain and fatigue. Understanding these challenges better could lead to improved support and interventions. This study explores a new way to monitor the daily experiences of patients with IRDs using Ecological Momentary Assessment (EMA), a method that collects real-time data through a mobile app. The study will also use actimeters-wearable devices that track physical activity. Over 14 days, participants will answer short surveys on their phone and wear an actimeter to provide insights into how fatigue, pain, mood, and physical activity levels change throughout the day. Before using this approach in a larger study, we need to make sure it is practical and acceptable for patients. This pilot study will assess whether participants find the mobile app and actimeter easy to use, how often they respond to surveys, and whether frequent reminders affect their willingness to participate. The study will also examine the immediate and delayed effects of different symptoms on physical activity and explore factors that influence patient engagement with the protocol. By identifying potential barriers and solutions, this research will help refine future studies and improve the way we monitor and support people with IRDs in staying active while managing their symptoms.
Study Type
OBSERVATIONAL
Enrollment
50
Participants will be complete four daily EMA surveys via the Avicenna Research app (morning, 11 a.m., 3 p.m., and evening). Participants will be instructed to complete and submit each survey as soon as they see the app notification. If no response is provided within 15 minutes, a reminder notification will be sent. At the end of the 14-day period, devices will be returned using a prepaid envelope provided by the study team and participants will complete an end-of-study questionnaire to assess the acceptability of the study and will be invited to participate in a debriefing interview with a member of the research team.

Feasibility of a 14-day smartphone EMA protocol combined with actigraphy
Feasibility will be quantified on five pre-specified indicators: (1) attrition rates; measured by the number of participants who withdrew from the study, (2) the number and percentage of data collected from EMA surveys relative to the number of potential assessments, (3) the percentage of surveys that a participant started to complete, relative to the number of potential assessments, (4) time elapsed between the prompt and the start of the response to the survey, (5) adherence to actigraphy (the threshold is at least 21 hours of wear time over 24 hours, for 14 days).
Time frame: Day 1 to Day 14 after enrollment
Acceptability of a 14-day EMA protocol combined with actigraphy delivered via a mobile application
Acceptability will be assessed at follow-up using a structured questionnaire and semi-structured interviews. The questionnaire will evaluate participant satisfaction, perceived relevance, ease of use, and daily burden associated with EMA and actigraphy. Each item will be rated on a five-point Likert scale (1 = strongly disagree to 5 = strongly agree). Acceptability at the item level will be defined as ≥70% agreement on positively worded items and ≤30% agreement on negatively worded items. A score ≥3/5 will indicate acceptable validation of an item. In addition, semi-structured interviews will be conducted to explore participant experiences; with consent, sessions will be audio-recorded, transcribed in a non-verbatim format, and analyzed using content analysis to identify recurring themes.
Time frame: Day 1 to Day 14 after enrollment
Immediate and Lagged Effects on Physical Activity
To examine the temporal relationships between pain, fatigue, and sleep, considering their reciprocal influences and variations across different times of the day
Time frame: Day 1 to Day 14 after enrollment
Immediate and Lagged Effects of Determinants on Physical Activity
To describe both the immediate and lagged effects of these factors on objectively measured physical activity
Time frame: Day 1 to Day 14 after enrollment
Adherence and Acceptability of Two Actigraph Devices
To compare adherence to and acceptability of two actigraph devices assessing physical activity, sleep, and sedentary behavior, worn at two different body sites
Time frame: Day 1 to Day 14 after enrollment
Patient-Perceived Acceptability
To explore the qualitative determinants of protocol acceptability directly from the patients' perspective
Time frame: Day 1 to Day 14 after enrollment
