SECONDARY outcome

Timeframe: Baseline, 4 weeks, 8 weeks, 12 weeks

A 5-item measure of rumination (brooding) assessing how often participants engage with each of the 5 behaviors on a scale from almost never (1) to almost always (4). Ratings are summed so that total scores can range from 5 to 20, with higher scores indicating more brooding in the past month.
