Interdependence in Daily Life

The Interdependence in Daily Life (IDL) Study consists of two parallel experience sampling studies of individuals (n = 284) and couples (n = 278). Each study consists of an extensive intake survey, including incentivised economic games, and a 49-wave experience sampling phase. The couples study also includes two follow-ups (one week, two years). In both studies, participants were asked to report on the last situation they had experienced with another person or with their partner, respectively, and rate each situation on the Situational Interdependence Scale.

The data were collected by me, Catherine Molho, Francesca Righetti, and Daniel Balliet. A data publication describing the full dataset is in preparation. For now, the codebook and materials are available here. Please get in touch if you are interested in working with the IDL data.
