Hypothesized mediating effect of mindfulness on sleep quality and worry: (A) Mindfulness training (delivered by the Unwinding Anxiety application) decreases worry, as measured by the Penn State Worry Questionnaire, which, in turn, mediates the effect of the intervention on sleep quality. (B) Mindfulness training increases non-reactivity, as measured by the non-reactivity subscale of the Five Facet Mindfulness Questionnaire, which, in turn, mediates the effect of the intervention on worry.
