| Summary: | Retrospective questionnaire methodology designed to survey individuals' exposures and experiences to real-world stimuli is susceptible various types of recall biases. EcologicalMomentary Assessment (EMA) investigates individuals´ behaviour and experiences in real time by asking them to document their experience as soon as possible after exposure. This presentation reports some preliminary results from a study where a total of 114 participants in northern Sweden, comprised of 53 sound or smell hypersensitive persons (age: M=56, SD=12.7) and 61 non-hypersensitive individuals (age: M=61.1, SD=10.8), were surveyed through a questionnaire twice with a three-month period in between about exposure and experiences with unpleasant sounds and smells. During the three-month period, participates used a smartphone app to document incidents and experiences of unpleasant sounds between questionnaires. This presentation will discuss the similarities and differences observed between the results of the questionnaires and EMA as well as address methodological advantages and challenges presented by collecting EMA using a smartphone app system.
