Daily average descriptive statistics were calculated for each participant, for each variable, and then those individual values were averaged across the entire sample representing sample averages for the 7-day study period; M mean; SD standard deviation; RMSSD root mean squares of successive difference, an overall indicator of variability in the measure, higher values = greater variability. PSI items were rated by participants on a 7-point Likert scale of enjoyment from 1 (not enjoyable at all) to 7 (extremely enjoyable); NSI items were rated by participants on 7-point Likert scale of distress from 1 (not distressing at all) to 7 (extremely distressing)
