Brief Summary
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. A better understanding of these challenges 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 phones and wear an actimeter to provide insights into how fatigue, pain, mood, and physical activity levels change throughout the day. Before this approach is implemented in a larger study, its practicality and acceptability for patients must be evaluated. This pilot study will assess whether participants find the mobile app and actimeter easy to use, how often surveys are completed, and whether frequent reminders affect participants' willingness to continue. The study will also examine the immediate and delayed effects of different symptoms on physical activity and explore factors that influence participant engagement with the protocol. By identifying potential barriers and solutions, this research will help refine future studies and improve methods for monitoring and supporting individuals with IRDs in staying active while managing symptoms.

Outcome Measures
Primary Outcomes (2)
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).
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.

Interventions
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.
