In this study, 64 individuals with worry interfering with sleep will be randomized to receive
Unwinding Anxiety or to wait-list control (50/50 chance). The active intervention period will
last 2 months, with an optional 2-month follow-up period in which the intervention remains
available. Changes in mindfulness, emotional reactivity, cognition and sleep behavior at
specified time points will be measured. The primary engagement targets will be non-reactivity
and worry. The primary behavioral outcome target will be sleep.
