Abstract

Personality researchers have posited multiple ways in which the relations between personality traits and life outcomes may be moderated by other traits, but there are well-known difficulties in reliable detection of such trait-by-trait interaction effects. Estimating the prevalence and magnitude base rates of trait-by-trait interactions would help to assess whether a given study is suited to detect interaction effects. We used the Life Outcomes of Personality Replication Project dataset to estimate the prevalence, nature, and magnitude of trait-by-trait interactions across 81 self-reported life outcomes (n ≥ 1350 per outcome). Outcome samples were divided into two halves to examine the replicability of observed interaction effects using both traditional and machine learning indices. The study was adequately powered (1 − β ≥ .80) to detect the smallest interaction effects of interest (interactions accounting for a ΔR2 of approximately .01) for 78 of the 81 (96%) outcomes in each of the partitioned samples. Results showed that only 40 interactions (5.33% of the original 750 tests) showed evidence of strong replicability through robustness checks (i.e., demographic covariates, Tobit regression, and ordinal regression). Interactions were also uniformly small in magnitude. Future directions for research on trait-by-trait interactions are discussed.

五大人格特征是否相互作用来预测生活结果?系统地测试各性状调节的普遍性、性质和效应大小
人格研究人员已经提出了多种人格特质和生活结果之间的关系可能被其他特质所缓和的方式,但众所周知,在可靠地检测这种特质与特质之间的相互作用效应方面存在困难。估计性状间相互作用的普遍程度和基本比率将有助于评估一项给定的研究是否适合检测相互作用效应。我们使用人格复制项目的生活结果数据集来估计81个自我报告的生活结果(每个结果n≥1350)中特质-特质相互作用的普遍性、性质和程度。结果样本被分成两半,使用传统和机器学习指标来检验观察到的相互作用效应的可重复性。该研究有足够的功率(1−β≥0.80)来检测每个分割样本中81个(96%)结果中的78个(约为0.01)的最小相互作用效应(相互作用占ΔR2)。结果显示,通过稳健性检查(即人口统计学协变量、Tobit回归和有序回归),只有40个相互作用(原始750个试验的5.33%)显示出强可复制性的证据。相互作用的量级也一致很小。最后讨论了性状间相互作用的研究方向。

期刊介绍: It is intended that the journal reflects all areas of current personality psychology. The Journal emphasizes (1) human individuality as manifested in cognitive processes, emotional and motivational functioning, and their physiological and genetic underpinnings, and personal ways of interacting with the environment, (2) individual differences in personality structure and dynamics, (3) studies of intelligence and interindividual differences in cognitive functioning, and (4) development of personality differences as revealed by cross-sectional and longitudinal studies.
