Trial Outcomes & Findings for The Impact of Standardized Tobacco Product Packaging on Young Adults in the Retail Environment (NCT NCT05973981)

Last Updated: 2025-10-29

Results Overview

Motivation to quit smoking as assessed by the Motivation to Stop Scale (MTSS; Kotz et al., 2013; Drug and Alcohol Dependence) participants endorsing one of 7 items: 1. = I don't want to stop smoking. 2. = I think I should stop smoking but don't really want to. 3. = I want to stop smoking but haven't thought about when. 4. = I REALLY want to stop smoking but I don't know when I will. 5. = I want to stop smoking and hope to soon. 6. = I REALLY want to stop smoking and intend to in the next 3 months. 7. = I REALLY want to stop smoking and intend to in the next month.
