Підсумок	Ecological momentary assessment (EMA), introduced to behavioral medicine by Stone and Shiffman in 1994, is a method of repeatedly sampling people's experiences in real time and in their natural environments rather than relying on retrospective questionnaires. Applied to disability research, EMA captures momentary, disability-relevant states — pain, fatigue, mood, symptom interference, and participation in daily activities — as they occur, typically through prompts delivered on a smartphone many times a day. By measuring experience in the moment and in context, EMA reduces the recall bias that distorts global retrospective reports and exposes the within-person variability and momentary person-environment interactions that aggregate scores hide. Prompts may be signal-contingent (delivered at random or scheduled times), event-contingent (triggered when a defined event occurs), or interval-contingent (at fixed intervals), and the resulting intensive longitudinal data are analyzed with multilevel models that separate within-person dynamics from between-person differences. EMA has become a cornerstone for studying how disability is actually lived day to day.	An activity diary, or time-use diary, is a structured record in which a person logs the activities they do across a day, how long each takes, and the context in which it happens; in disability research the method is adapted to capture daily activity participation, time allocation, the assistance people use, and the barriers they encounter. Diaries may cover a full 24-hour day in sequential slots or sample episodes throughout the day, and they record not only what the person did but where, with whom, with what human or device assistance, and against what obstacles. Aggregating these records yields indicators of how time is spent and how fully a person participates in life domains, which can be mapped onto the Activities and Participation component of the World Health Organization's International Classification of Functioning, Disability and Health (ICF). By grounding measurement in concrete daily activity and environmental context, activity diaries complement momentary and clinical measures and reveal the lived texture of participation that summary functional scores miss.
