Dual-process Mechanisms of Action for sipIT Intervention Effects in Patients With Urolithiasis

The study is a six-month ecological momentary assessment study of patients using the mini-sipIT intervention for 3 months, with weekly assessments of motivation and life events or stressors that disrupt routines during the 3-month intervention period, and monthly assessments of motivation and life events or stressors that disrupt routines in the three months following the end of intervention (months 4-6). The mini-sipIT intervention includes automated and manual tracking of fluid intake and lapse-contingent reminders to drink.
