The APA Style team would like to recognize the passing of Dr. Mark Appelbaum in December 2020. Dr. Appelbaum was an accomplished researcher with interests in quantitative psychology and psychometrics whose work had a profound impact on psychological research. At the time of his passing, he served as an emeritus professor of psychology at the University of California, San Diego. Previously, he served at several other institutions, including as a psychology faculty member and associate dean at UNC Chapel Hill for 21 years.
Dr. Appelbaum worked very closely with the American Psychological Association in many capacities. He was the founding editor of Psychological Methods and an editor for Psychological Bulletin. He served in several groups including the APA Task Force for Violent Media, APA Working Group on Quantitative Research Reporting Standards, and Publication Manual Revision Task Force.
The APA Style team got to know Dr. Appelbaum very well through his work on the Publication Manual of the American Psychological Association. He worked on multiple editions of the Publication Manual, including the seventh edition released in 2019. Dr. Appelbaum also collaborated with the APA Style team while developing the APA Style Journal Article Reporting Standards (APA Style JARS) in 2008 and leading the revision and expansion of APA Style JARS for quantitative research designs (JARS-Quant) in 2018.
Dr. Appelbaum’s interests in quantitative research, psychometrics, applied statistics, experimental design, and data analytic methods; his extensive research and teaching background; and his love for improving the communication of research made him a valuable contributor to APA Style and the field of psychology as a whole. Dr. Appelbaum was generous with his time and a pleasure to work with as he shared his great depth of historical and institutional knowledge while working with the APA Style team to iron out complex issues.
Dr. Appelbaum will be greatly missed.
