The experience sampling method (ESM) is applied in ambulatory assessment to prompt subject self-reporting. Existing mobile apps provide time-triggered prompts but lack event-triggers. Hence, the sampling might not occur in moments that are of interest for a psychologist. To identify relevant sensor sources and contexts we conducted an online survey with ambulatory assessment experts. Most relevant for these experts are time, date and user activity, followed by location, notifications and accelerometer. A feasibility test proved that all relevant sources are accessible on Android phones. We also assessed the desired granularity of the data gathered from each sensor source. Our results are a first step towards an ESM platform to create context-aware Android apps for ambulatory assessment. |
