The purpose of this study is to investigate if a change in psychological well-being can result from engagement in creative activity. In an online experimental study participants will be randomly assigned to solve either a creative or a non-creative task. Their experience of completing the task will be compared with their average daily well-being level. Involvement in a creative task is expected to boost both positive feelings (hedonic well-being) and good functioning (eudaimonic well-being). Personal characteristics, such as a need for closure, and task features, e.g. difficulty level, will also be tested for their moderating effects.
