Participant Database

Although psychological research is not only scientifically but increasingly also socially relevant (e.g., increase in anxiety disorders), it is unfortunately all the more difficult to recruit subjects for studies. Especially longitudinal studies (i.e., repeated measurement in the everyday life of the test subject) can often only be realized with increased effort, although they have a substantial added value - compared to classical one-time cross-sectional studies (i.e., one-time completion of a questionnaire) - (only in German).
