Abstract
We use z-curve analysis to estimate the replicability of 187 moderation effects in which the predictor, outcome, and moderator variables were all measured continuously and that were published in four leading personality journals—Journal of Personality, Journal of Research in Personality, European Journal of Personality, and Personality and Individual Differences. We found an estimated replication rate of 43.80%; that studies published after 2015 performed slightly better than studies published before 2015; and that studies published in the Journal of Research in Personality and the European Journal of Personality performed worse than studies published in the other two journals. We discuss the implications of our findings for studying moderation effects in personality and offer recommendations for improving the replicability of published studies.
期刊介绍：
Emphasizing experimental and descriptive research, the Journal of Research in Personality presents articles that examine important issues in the field of personality and in related fields basic to the understanding of personality. The subject matter includes treatments of genetic, physiological, motivational, learning, perceptual, cognitive, and social processes of both normal and abnormal kinds in human and animal subjects. Features: • Papers that present integrated sets of studies that address significant theoretical issues relating to personality. • Theoretical papers and critical reviews of current experimental and methodological interest. • Single, well-designed studies of an innovative nature. • Brief reports, including replication or null result studies of previously reported findings, or a well-designed studies addressing questions of limited scope.
