Therapeutic Contact Intensity in a Psychological Smoking Cessation Intervention With an App

This randomized controlled trial intends to examine the efficacy of a smoking cessation intervention with an App according to the intensity of therapeutic contact. Participants will be assigned to one of three groups. The first group will receive eight sessions with trained psychologists alongside access to the App. The second group will receive four sessions with trained psychologists plus App access. The control group will only have access to the App. This study seeks to determine the impact of different levels of therapeutic contact on abstinence outcomes.
