Data from, ‘Web-based Positive Psychology Interventions: A Reexamination of Effectiveness’

We present two datasets. The first dataset comprises 992 point-in-time records of self-reported happiness and depression in 295 participants, each assigned to one of four intervention groups, in a study of the effect of web-based positive-psychology interventions. Each point-in-time measurement consists of a participant's responses to the 24 items of the Authentic Happiness Inventory and to the 20 items of the Center for Epidemiological Studies Depression (CES-D) scale. Measurements were sought at the time of each participant's enrolment in the study and on five subsequent occasions, the last being approximately 189 days after enrolment. The second dataset contains basic demographic information about each participant. The data are suitable for replication purpose and for various time-series analyses and between-group comparisons. The authors welcome collaborative research based on re-analyses of the data.
