Replicability-Report for EUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY

is published by Wiley. The journal started publishing articles in 1971.

SCImago ranks EUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY as #127 of all psychology journals with an SJR-Impact-Factor of 1.5 in 2014. The replicability-report is based on articles published from 1990 to 2015. Since 1990, the journal published 1,567 articles. The replicability-report is based on 1,118 articles that reported one or more t or F-test in the text of the results section (results reported in Figures or Tables are not included).  The test-statistic was converted into z-scores to estimate post-hoc-power.  The analysis is based on 7,419 z-scores in the range from 2, just above the 1.96 criterion value for p < .05 (two-tailed), to 4.

PHP-Curve EJSP

Based on the distribution of z-scores in the range between 2 and 4, the average power for significant results in this range is estimated to be 58%. This estimate suggests that 58% of the published significant results in this range are predicted to produce a significant results in an exact replication study with the same sample size and power (results with z > 4 are expected to replicate with nearly 100%).

The same method was used to estimate power for individual years.

PHP-Trend EJSP

The results show a decreasing trend. The replicability scores in the past 4 years have been below the historic average. The replicability score in 2015 was 52. There is no sign that the journal has responded to the replicability crisis in psychology by publishing studies with higher power.  The score for 2015 can still change as more data become available.
