Abstract:The Experience Sampling Method (ESM) is receiving increasing attention in the field of health and social research and has already been implemented by numerous researchers. This method turned out to be a powerful addition to more conventional survey studies, because it allows the researcher to study psychological constructs in flux. Surprisingly, little attention has been paid to the psychometric properties of ESM questions. Therefore, the current study aims to contribute to this growing interest in the ESM by assessing test-retest reliability and convergent validity of ESM questions in the framework of measuring core affect. A repeated measures design study in the framework of the ESM with signal-contingent reporting was conducted, in which 19 people were asked to respond to the Affect Grid, six times a day, i.e. every two hours between 10 AM and 8 PM, for one week via a smartphone application. Besides the Affect Grid, which served as the ESM question, participants had to complete the Positive and Negative Affect Scale (PANAS), which was assumed to be a converging survey. Overall, the findings suggest that the Affect Grid is a reliable and valid tool for assessing core affect in terms of the affective home base.
