Heart rate
Analysis of HR data during the tasks (n = 90) revealed a significant
effect of task, F(1, 87) = 36.97, p < 0.001, partial
2 = 0.30, such that HR was lower during the second stressor
(post-treatment) than the first (pre-treatment). However,
there was no significant effect of group and no signifi-
cant interaction between task and group, indicating that
all groups showed similarly decreased stress reactivity (see
Table 2). Additionally, there was no significant effect of time
during the tasks, suggesting that HR did not habituate duringeach stressor. Furthermore, there were no significant group
differences during the intervention itself (n = 103)
