Replicability Report for JOURNAL OF SOCIAL AND PERSONAL RELATIONSHIPS

JOURNAL OF SOCIAL AND PERSONAL RELATIONSHIPS (JSPR) is published by SAGE. The journal started publishing articles in 1984.

SCImago ranks JSPR as #260 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 2003 to 2015. During this time, JSPR published 668 articles. The replicability report is based on 403 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 1,454 z-scores in the range from 2 (just above the 1.96 criterion value for p < .05 (two-tailed)) to 4.
PHP-Curve JSPR
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 63% 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 56% power in this range.  Power for all significant results is estimated to be 68%.  A power estimate of 63% implies that 63% 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 JSPRThe time trend shows a pronounced negative trend. Power estimates in the past four years were below the historic average.  The average power for the years 2010-2014 is 56%, which is below the historic average.  The current power estimate for 2015 is 39%, which places JSPR at the bottom of the replicability rankings of psychology journals. Hopefully, the new editor of JSPR will be able to respond to the replicability crisis in psychology and increase the replicability of results published in JSPR.
