Filter by:This project will be conducted to investigate activities on housing-related health and safety issues. The focus of this project is the development of evidence-based approaches to implement smoke-free policies to reduce harms associated with exposure to secondhand smoke (SHS).
The study will use functional magnetic resonance imaging and facial coding methods to study individuals who smoke cigarettes. Smoking expectancy (the extent to which one perceives an opportunity to smoke a cigarette) will be manipulated using instructions, and the investigators will examine the effects of this manipulation on two primary endpoints under conditions designed to induce an urge to smoke: (1) brain responses measured using fMRI and (2) subjective affective responses measured using facial coding. Secondary endpoints include self-report measures of the desire to smoke and current affect.
This is a multicenter, post market surveillance study designed to evaluate biomarkers of tobacco exposure and effect, health status measurements, and tobacco product usage patterns in subjects who are natural adopters of cigarettes and/or smokeless tobacco. Non tobacco users will serve as a non use comparison group. This study is unblinded by necessity due to the very different visual appearance of the subject's Usual Brand (UB) of tobacco product(s).
Prospective open label, single center study enrolling up to 220 participants to evaluate the effect of the Pivot Breath Sensor on a user's attitudes towards quitting smoking and smoking behavior.
The overall goal of this pilot study is to solicit feedback from nondaily smokers looking for smoking cessation support online (n=90) about Version 2 of a smartphone app investigators designed to support smoking cessation, and to test if within-person theorized mechanisms of change are occurring as participants undergo the app-assisted quit attempt. Data sources will be passively collected smartphone app usage data, surveys and, in a sub-sample (n=20), online video-conference user feedback sessions. Results will be used to guide the design of Version 3.0 of the "Smiling Instead of Smoking" (SiS) smartphone app. Specifically, the aims of this study are to: 1. Assess ease-of-use and helpfulness of the app, as rated by app users 6 weeks after their chosen smoking cessation date 2. Test if within-person changes occur in theorized mechanisms of behavior change as nondaily smokers undergo a SiS app assisted quit attempt 3. Identify app features in need of improvement, as identified by passively recorded app usage patterns, REDCap open-ended survey items, and, in a sub-sample, user feedback sessions (n=20)
Randomized, double-blind, before-after controlled trial to assess changes in regional brain activation in response to cigarette-related cues from before to after treatment with bupropion (vs placebo).
This project will develop and refine a computer-delivered integrated Personalized Feedback Intervention (PFI) that directly addresses smoking and distress tolerance. The PFI will focus on feedback about smoking behavior, distress tolerance, and adaptive coping strategies.
A randomized controlled trial to evaluate the effectiveness of smoking reduction interventions for smoking parents in paediatric hospital setting in Hong Kong.
A clinical study enrolling 70 subjects to: - evaluate the user performance of the Pivot Breath Sensor - compare measurements from the Pivot Breath Sensor to a similar device - assess user documentation comprehension - obtain feedback on the Pivot Breath Sensor via rating scales. No medical decisions will be made related to test results.
Prospective, observational open label, single center study enrolling up to 15 subjects to evaluate human factors and usability of the Pivot Breath Sensor.
