  1. N number. N = 1476 for all data. N = 292 for the subset. *Statistically significant test statistics (p < .002). Descriptive statistics were calculated with all ratings scaled to a range from 1 to 7. For Bartels rank test, results were considered significant for p < .002. The KPSS test only provides p values between .010 and .100. For the KPSS test, p = .010 was therefore considered significant. Three items showed no variance during the baseline period included in the subset and were therefore omitted from analysis of the subset
