Therapeutic Contact Intensity for a Smoking Cessation App Intervention

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized trial, adults who smoke at least five cigarettes a day are assigned to one of three groups: eight CBT sessions with app access, four CBT sessions with app access, or app access alone. The study uses video calls to deliver cognitive-behavioral therapy focused on mood, activity, and social support, alongside a digital smoking cessation app. The goal is to see if higher therapeutic contact improves abstinence rates at follow-up compared with app use alone. Outcomes will guide how to optimize digital and clinician-assisted smoking cessation approaches.
