Finally, no studies have tested whether there are interactive
effects of pre-existing dispositional mindfulness and
mindfulness meditation training on stress reactivity. One
recent study suggests that more dispositionally mindful participants
are more responsive to training, showing greater
increases in subjective well-being and decreases in stress
symptoms after eight weeks of mindfulness training (Shapiro
et al., 2011). The present study is the first to test for
interactive effects of dispositional mindfulness and brief
mindfulness training on stress reactivity to the TSST. This
investigation of moderation has practical value: it can determine
whether certain individuals respond to mindfulness
training to a greater or lesser degree than others.
