Experience sampling method
The experience sampling method, also referred to as a daily diary method, or ecological momentary assessment (EMA), is an intensive longitudinal research methodology that involves asking participants to report on their thoughts, feelings, behaviors, and/or environment on multiple occasions over time. Participants report on their thoughts, feelings, behaviors, and/or environment in the moment (right then, not later; right there, not elsewhere) or shortly thereafter. Participants can be given a journal with many identical pages. Each page can have a psychometric scale, open-ended questions, or anything else used to assess their condition in that place and time. ESM studies can also operate fully automatized on portable electronic devices or via the internet. The experience sampling method was developed by Larson and Csikszentmihalyi.
There are different ways to signal participants when to take notes in their journal or complete a questionnaire, like using preprogrammed stopwatches. An observer can have an identically programmed stopwatch, so the observer can record specific events as the participants are recording their feelings or other behaviors. It is best to avoid letting subjects know in advance when they will record their feelings, so they can't anticipate the event, and will just be "acting naturally" when they stop and take notes on their current condition. Conversely, some statistical techniques require roughly equidistant time intervals, which has the limitation that assessments can be anticipated. Validity in these studies comes from repetition, so you can look for patterns, like participants reporting greater happiness right after meals. These correlations can then be tested by other means for cause and effect, such as vector autoregression, since ESM just shows correlation.
Some authors also use the term experience sampling to encompass passive data derived from sources such as smartphones, wearable sensors, the Internet of Things, email and social media that do not require explicit input from participants. These methods can be advantageous as they impose less demand on participants improving compliance and allowing data to be collected for much longer periods, are less likely to change the behaviour being studied and allow data to be sampled at much higher rates and with greater precision. Many research questions can benefit from both active and passive forms of experience sampling.
iHabit was the first smartphone platform for ESM. It was developed in 2011 and used in a study published by PLOS One in 2013. The creators of iHabit released their second platform, the LifeData system, in 2015, which was used in a study published by JAMA Pediatrics in 2016. This was soon followed by the PIEL Survey (first version 2012) which has since been used in more than 12 academic publications. Other early smartphone platforms for ESM include SurveySignal and Ilumivu (developed in 2012), MetricWire (developed in 2013), Instant Survey, Movisens, and Aware (Open Source). The largest ESM study was achieved through PSYT's Mappiness App, PSYT’s apps collect data through ESM as well as reporting the data back to users to enable real-time visualisation and tracking of variables. Several other commercial and open source systems are currently available to help researchers run ESM studies, including BeepMe, and Expimetrics. Physiqual enables researchers to gather and integrate data from commercially available sensors and service providers to use them in ESM, including Fitbit and Google Fit. As of 2014, Movisens have developed the ability to trigger sampling forms from physiological data such as actigraphy and ECG. unforgettable.me provide a platform for both active and passive experience sampling that allows the integration of some 400 data sources.
