The way we feel and what positive emotions we report can change from moment to moment. Surprisingly, most research into our feelings has ignored this dynamic aspect. It focused more on important issues such as to what extent emotion as a state (e.g. ‘on average this is an angry person’) has certain antecedents and consequences. However, with the advent of the experience sampling method (or ecological momentary assessment) researchers have begun to study fluctuations in feelings (e.g. Kuppens, Oravecz, & Tuerlinckx, 2010). With this method participants answer a set of short questions repeatedly during the day, and sometimes this daily questioning is done for months. With this detailed information for every individual the change in feeling can be monitored and connected to psychopathology, personality differences, gender and even physiological changes.


For the experience sampling method, just as for classical survey research, the validity and reliability of the questions are very important for research and clinical application (Palmier-Claus et al., 2011; Versluis et al., 2018). In this bachelor project you will study the reliability and validity of a limited number of questions pertaining to positive psychology (e.g. self-compassion; Neff, 2003)),  suitable for experience sampling. Your will do a concise review of the literature on these positive psychology constructs and examine the reliability and validity of one (or possibly more)  short  questions in a sample (and associated language) relevant for the student population at the University of Twente. You will also use and test the TiiM app developed (partly) for experience sampling purposes.



Who are we looking for?

Two enthusiastic students who are interested in the way the everyday positive psychology constructs can be measured in a reliable and valid way. This is important for both research and clinical applications.
