| Authors: | W A Arrindell C Gerlsma |
| Abstract: | For 443 men and women of the general population and mean age of 45.8 yr. state and trait measures were obtained on two occasions, 6 mo. apart. Internal consistencies at each time were similar (.84-.95). Test-retest coefficients were lower for measures of state concepts than for trait concepts. Howarth's mu indices were higher for state concepts than for trait concepts. |
