Replicability Report for PERSONAL RELATIONSHIPS

PERSONAL RELATIONSHIPS is published by Wiley. The journal started publishing articles in 1994.

SCImago ranks PERSONAL RELATIONSHIPS as #238 of all psychology journals with an SJR-Impact-Factor of 1.0 in 2014. At present, the replicability report is based on articles published from 2000 to 2015. During this time, PERSONAL RELATIONSHIPS published 564 articles. The replicability report is based on 405 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 1,469 z-scores in the range from 2 (just above the 1.96 criterion value for p < .05 (two-tailed)) to 4.

PHP-Curve PersRelBased 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 57% with the homogeneous model that is currently being used for the replicability rankings. The heterogeneous model fits the actual data better and produces an estimate of 51% power in this range.  Power for all significant results is estimated to be 65%.  A power estimate of 57% implies that 57% 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 PersRelThe time trend is slightly negative. The average for the years 2010-2014 is 52%, which is close to the historic average.  The current power estimate for 2015 is 52%.  These results show no evidence of improvements in replicability in response to the replicability crisis in psychology.
