Statistical analysis
Five one-way ANOVAs were used to examine whether the groups differed in their motivation and interest in the assigned training, in training attendance, formal practice, and informal practice. Differences between groups were then controlled and measures of interest (schadenfreude, and closeness) and the manipulation check (compassion) were analyzed with repeated-measures ANCOVAs. Our hypotheses were tested by planned contrasts. All data were analyzed using Statistica version 14.0.0 and the R version 3.5.1 and the packages “psych”, “car”, & “MBESS”.
