Replicability Report for the journal SOCIAL PSYCHOLOGY

The journal SOCIAL PSYCHOLOGY is published by Hogrefe.  The journal was published under the title Zeitschrift für Sozialpsychologie in German until 2007. This replicability report covers the years since 2008.

SCImago rankings of all psychology journals ranked SOCIAL PSYCHOLOGY #286 with an SJR-Impact-Factor of 0.9 in 2014.

At present, the replicability-report is based on articles published from 2008 to 2015.  During this time, SOCIAL PSYCHOLOGY published 293 articles.  The Replicability-Report is based on 223 articles that reported one or more t or F-test in the text (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 1,064 z-scores in the range from 2 (just above the 1.96 criterion value for p < .05 (two-tailed) to 4.

PHP-Curve ZSPBased 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 61% with a homogeneous model, which is currently being used for the replicability ranking.  The average power assuming heterogeneity is 56%.  This estimate suggests that 56% of the published results with z-scores in this range yield 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 ZSPThe results show a flat time trend.
