sciences of the University of Amsterdam.
- The level of significance used in this procedure was
a=0.05. Reliability factors for the scales are: (scale 1) rho=0.91;
(scale 2) rho=0.72; (scale 3)
- On an individual level it might be possible that respondents

Gender high means female, steady partner high means having a steady
