Methods for studying daily life have blossomed since the 1980s. Although these methods have been around for years, their popularity is always increasing as technological innovations have made the use of these methods easier and more reliable to employ. Methods for studying daily life typically include taking repeated real-time assessments of individual behaviors, physiology, and/or psychological experiences, over the course of an individual’s everyday life. These methods include experience sampling methodology (ESM), ecological momentary assessments (EMA), ambulatory assessments (AA), and daily diary or day reconstruction methods. All of these methods include repeated or detailed assessments of daily- life experiences but vary in terms of the frequency of assessments, technological tools to administer assessments, and timing of assessments (e.g., real time assessments versus retrospective recall). Given that these methods are intended to capture observations of psychological experiences in daily life, they require careful consideration of study design, measurements, and assessment tools. This article will provide a general overview of daily-life methods, including discussions about the different study designs and sampling methods. Furthermore, it will describe the advantages and limitations of using these methods along with examples of empirical studies that illustrate the usefulness of these techniques. It will also provide information on important considerations for sampling and measuring experiences in daily life and provide examples of the technology available for daily-life assessments.
