Clinical Trial Summary

The aim of this study is to analyze the efficacy of several variations of an already validated Positive Psychology Intervention (PPI) called Best Possible Self, using Information and Communication Technologies (ICT) in general population. Participants are randomly assigned to one of 4 conditions: BPS PAST condition, BPS PRESENT condition, BPS FUTURE condition, and CONTROL condition (daily activities).

Description:

Intervention lasts 7 days. Participants come to the laboratory the first day, they fill up assessment questionnaires and practice the assigned exercise. Then, they practice the assigned exercise for 6 more days at home.

The main hypothesis is that all three experimental conditions will enhance wellbeing comparing to the control condition.
