本研究考察了两种广泛使用的正常人格评估工具--修订版NEO人格量表（NEO PI-R）和人际形容词量表（IAS）的内部一致性和时间稳定性。著名的成人目标选择了109名本科生，并在两个场合相隔6个月的时间间隔进行评级。除了少数例外，内部一致性的估计是足够好的两个工具。NEO PI-R领域得分的产出系数α范围为0.89至0.96，30个方面量表的中位数为0.80。IAS八分圆刻度显示系数α的范围为0.83至0.92。每个NEO PI-R域评分和两个IAS轴坐标的重测Pearson相关性均高于0.70，两种工具的所有量表的组内相关性均高于0.60。在重新测试时，五个NEO PI-R域中的三个域的分数变化很小，但具有统计学意义。IAS类型分类的重测稳定性随着相关八分圆分数的极端而变化。
This study examines the internal consistency and temporal stability of informant ratings from two widely used instruments for normal personality assessment, the revised NEO Personality Inventory (NEO PI-R) and the Interpersonal Adjective Scales (IAS). Well-known adult targets were selected by 109 undergraduate students and rated on two occasions separated by a 6-month interval. With few exceptions, estimates of internal consistency are adequate to good for both instruments. NEO PI-R domain scores yield coefficient alphas ranging from .89 to .96, with a median of .80 for the 30 facet scales. IAS octant scales show coefficient alphas ranging from .83 to .92. Retest Pearson correlations are above .70 for each of the NEO PI-R domain scores and both IAS axis coordinates, and intraclass correlations are above .60 for all scales from both instruments. Score changes were small but statistically significant for three of the five NEO PI-R domains at retest. The retest stability of IAS type classifications varies as a function of the extremity of the associated octant scores.
