Note: SUD = substance use disorder, SMS = short message service. The total sample size
for the study was 251. The respective n’s next to each item represent the number of patients
for whom we have data for that item. For demographic data and for owning a mobile
phone post treatment, sample sizes less than 251 are due to missing data (e.g., the patient
did not answer that question or ended the interview early). For the technology utilization
items all patients were asked whether they owned a mobile phone prior to treatment and
whether they anticipated owning a mobile phone post treatment. Only patients who endorsed
“yes” for these items were queried with subsequent items.
