SECONDARY outcome

Timeframe: time (in minutes) spent completing homework from CPT session 1 to CPT session 12 (across approximately 6 weeks, weeks 7-12 after baseline)

Population: Number of participants reflect only those participants who completed at least 2 sessions of CPT (i.e., enough sessions to complete at least one homework assignment)

At each of the CPT sessions, participants will report how much time they spent completing homework since the previous session
