Operationalization
T1: After baseline assessment students were randomly assisgned to two treatments.

A. ACTIVITY CHANGE GROUP. Participants were asked to attempt something which might influence their mood. Then they were asked to identify a goal or activity change they could make during the next two weeks

B: CIRCUMSTANCE CHANGE GROUP. Participants were asked to attempt something which might influence their mood. Then they were asked to identify a circumstance they could change.

T2:. Participants completed questionnaires immediately after identifying the goals.

T3: After two weeks participants were asked whether they actually made the change they said they would make. If yes, the students were asked to rate the variety of their change. Lead item: To what extent is the change something that varies over time, i.e. something that adds variety to your life? Rated 1 = not at all to 5  = very much. In both groups only participants who really made the change were included in the analyses.

Because there were no differences in outcomes between the groups, analyses were performed for both groups together .

Happiness assessed at:
