Key result
Activity disruption in T1D is linked to lower QoL and higher stress.
Why the study?
Living with T1D disrupts daily routines and emotional experiences, but few studies have examined how momentary activity disruptions affect psychosocial well-being in real time.

Does activity disruption affect psychosocial well-being and emotional states in adults with Type 1 Diabetes?
Effect estimate: Std β range: |0.32-0.43| for psychosocial outcomes; Std β range: |0.05-0.13| for momentary states
Activity disruption in adults with Type 1 Diabetes acts as a daily stressor with immediate emotional reactivity and cumulative negative impacts on overall well-being.
Activity disruption may flag T1D patients needing support; hypothesis-generating, RCTs needed to test causality and interventions.
Introduction and Objective: Living with T1D is inherently disruptive, affecting daily routines and emotional experiences. Few studies have examined how momentary activity disruptions affect psychosocial well-being in real time. This study aims to investigate both the immediate and cumulative effects of activity disruption on emotional states and psychosocial outcomes among adults with T1D. Methods: Data were drawn from an intensive ecological momentary assessment (EMA) study named Function and Emotion in Everyday Life with T1D (FEEL-T1D). Adults with T1D completed 14 days of EMA (5-6 prompts/day), reporting current activity, diabetes-related disruption, affect, and stress (general and diabetes-related). Follow-up psychosocial measures included diabetes distress (Problem Areas in Diabetes, PAID) perceived stress (Perceived Stress Scale, PSS), mental health (SF-36 mental component score), and T1D QoL (Helmsley Quality of Life and Diabetes Survey). Multilevel and linear regression models were conducted, adjusting for demographic and device variables. Results: A total of 197 participants (18-75 yr; 54.6% male; 40.8% Hispanic) reported 14496 activities, of which 11.6% were disrupted. A greater activity disruption proportion was associated with lower QoL and SF-36 scores and higher PAID and PSS scores (Std β range: |0.32-0.43|). Within-person analyses showed that activity disruption predicted concurrent increases in negative affect, stress, and diabetes-related stress and decreases in positive affect (std β range: |0.05-0.13|). These effects did not persist until the subsequent survey hours later. (p =.12). Conclusion: Activity disruption functions as a daily stressor in adults with T1D, exerting both immediate emotional reactivity and longer-term psychosocial impact. While emotional effects appear transient, accumulative disruption is linked to poorer overall well-being. Diabetes care should account for activity disruption in both assessment and management.

Mo et al. (2026) conducted an observational in Type 1 Diabetes (n=197). Activity disruption vs. Lower or no activity disruption was evaluated on Psychosocial well-being (QoL, SF-36, PAID, PSS) and momentary emotional states (Std β range: |0.32-0.43| for psychosocial outcomes; Std β range: |0.05-0.13| for momentary states). Activity disruption in adults with Type 1 Diabetes was associated with lower quality of life and higher stress (Std β |0.32-0.43|), and predicted concurrent increases in negative affect.
