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.
针对443名普通人群（平均年龄45.8岁）的男性和女性，在两次测量中获取了状态和特质测量数据，两次测量间隔6个月。每次测量的内部一致性相似（0.84 - 0.95）。状态概念测量的重测系数低于特质概念测量的重测系数。状态概念的豪沃思μ指数高于特质概念的豪沃思μ指数。
