In February (part 1) and March (part 2) 2012, the LISS panel completed a questionnaire in which several personality characteristics were measured.
The UPCC (Utrecht Proactive Coping Competence scale) is a 21-item scale that measures whether individuals are able to set realistic goals, identify opportunities for acting upon goals, and deal with obstacles along the way. The main aim of the present study is to assess the validity and reliability of the UPCC in a representative sample of the general population.
In the second part respondents also got questions about eating snacks.
