Filter by:The approach and avoidance task (AAT) has evolved as a promising treatment add-on in the realm of psychology. Certain psychiatric diseases, such as behavioural addictions, social anxiety disorder, and arachnophobia, are characterized by a dysfunctional tendency to either approach or avoid disease-specific objects. This tendency can be measured by means of the approach and avoidance task. More precisely, by a diagnostic AAT, in which participants are instructed to react upon the format or the frame colour of a picture. For instance, pictures have to be pushed away if they are presented in landscape format and pulled towards oneself if they are presented in portrait format (or vice versa). Hence, the format (or the frame colour) becomes the task-relevant dimension, whereas the content of the picture becomes irrelevant for task completion. However, what generally becomes obvious in the psychiatric diseases mentioned above is that the task-irrelevant dimension (picture content) exerts an influence on reaction times. For instance, smokers are generally faster to respond to smoking-related pictures, when presented in a format requiring them to pull towards themselves, and slower to respond, if smoking pictures are shown in the format requiring them to push away a joystick (Wiers et al., 2013). This behavioural tendency has been termed an approach bias for cigarettes or smoking. In order to counteract these dysfunctional approach or avoidance tendencies, an AAT-training has been developed. In this training participants/patients learn to either avoid or approach disease-specific objects. Smokers, for instance, learn to avoid smoking-related pictures by pushing or swiping the image away. It has been shown that these trainings can lower cigarette consumption among current smokers (Machulska, Zlomuzica, Rinck, Assian, & Margraf, 2016). The aim of the current study is to test whether the avoidance gesture is as important as suggested by the AAT's name or whether inhibiting the urge to approach smoking-related content might be enough to bring about the effect. Furthermore, possible changes in general and domain-specific (i.e. smoking-related) inhibition capacity, that might mediate the effect, will be assessed. Another focus of study will be on functional as well as structural neuronal changes, emerging as a consequence of the AAT-training.
This study will evaluate a reward devaluation strategy in which smokers use the JUUL e-cigarette immediately before any combustible cigarettes (CCs) are smoked. This procedure is predicted to accomplish three goals: 1) the rewarding effects of CC will be disrupted because subjects will already have attained fairly high peak nicotine concentrations immediately before smoking the cigarette. This reduces the rewarding effect of smoking, in part from receptor desensitization that occurs following nicotine exposure, which reduces the response to a subsequent dose of nicotine, and in part from satiating the drive to smoke; 2) the use of the JUUL will become associated with the same cues that elicit smoking, thereby promoting the substitution of JUUL use for CC use; and 3) ad libitum nicotine intake from the JUUL and its rewarding effects will be maximized because, unlike CC, they will be experienced after a period of nicotine deprivation. Thus, despite a lower per-puff nicotine dose relative to CC, the pharmacologic impact and reinforcing effect will be maximized. The study will evaluate two flavors (Mint and Virginia Tobacco), randomly assigned, to determine if flavor assignment (similar to the subjects' usual brand of CC or different than the subjects usual brand CC) has an effect on the success of this reconditioning procedure.
This study assesses the effect of a personalized smoking cessation infographic on physician smoking cessation counseling rates and smoking cessation pharmacotherapy prescription rates. The study assesses the difference in physician behaviour using an interrupted time series analysis (one-year pre vs. one-year post-intervention). General practitioners, nurse practitioners and respirologists who refer eligible patients (COPD, active smoking) for spirometry at the St. Michael's Hospital Pulmonary Function Lab will receive the infographic. This is a quality improvement initiative. The smoking cessation infographic uses individualized patient data (height, weight, sex, baseline FEV1, etc.) to produce a personalized lung function decline prediction over the next 15 years.
This study aims to evaluate the effectiveness of a general health promotion (GHP) approach to motivate smokers with chronic diseases to quit smoking. Subjects in the intervention group will receive a brief Motivational Interviewing (MI) using a GHP approach. Subjects in the control group will receive a self-help booklet on smoking cessation at the time of recruitment.
To conduct a pilot study to determine the feasibility, potential efficacy and effect size of a personalized general health promotion approach using Information Communication Technology (WhatsApp or WeChat) to deliver a brief Motivational interviewing (MI) in promoting smoking cessation among smokers having follow-up in a Special Out-Patient Clinic (SOPC). In addition, this pilot study aims to assess the potential facilitators and barriers of future implementation of using such approach for smokers with chronic diseases. Based on the findings of the pilot study, a large RCT will be conducted to evaluate the effectiveness and costs of a personalized general health promotion approach in promoting smoking cessation for smokers with chronic diseases in Hong Kong in the future.
This is a research study about a smoking cessation program tailored for adults with serious mental illness (SMI). The program uses a Videogame-based Physical (VIP) activity, smoking cessation counseling, and medication (bupropion),
This study aims to evaluate the effectiveness of a general health promotion (GHP) approach using information communication technology (ICT) to deliver a brief motivational interviewing (MI) to motivate smokers with chronic diseases to quit smoking. Subjects in the intervention group will receive a GHP approach using ICT (e.g., WhatsApp/WeChat) to deliver brief MI. Subjects in the control group will receive an individual face-to-face generic health advice plus a self-help booklet on smoking cessation at the time of recruitment.
This study will look at the effectiveness of a new treatment protocol for anxious and depressed smokers. Participants with clinically significant anxiety or depression will receive either the standard smoking cessation treatment or the Unified Protocol for Smoking Cessation Treatment. This study will demonstrate that a single treatment protocol can effectively address both smoking and the complex emotional comorbidities that are widespread in smokers will provide a novel, impactful, and highly disseminable treatment option missing from today's smoking cessation arsenal.
Smokers living with HIV represent a major health disparity population in the United States and the world more generally. Major contributing factors to the maintenance and relapse of smoking among smokers living with HIV include increased exposure to multiple stressors associated with HIV, which often exacerbates anxiety/depression. In a previous project, the feasibility, acceptability, and initial efficacy of a 9-session, cognitive-behavioral-based intervention to address smoking cessation by reducing anxiety and depression via specific emotional vulnerabilities (anxiety sensitivity, distress tolerance, and anhedonia) was tested against an enhanced standard of care in a pilot randomized controlled trial (NCT01393301). It was found that when compared to a brief enhanced treatment as usual control, patients in the intervention achieved higher short-term and long-term smoking abstinence rates. In this project, the investigators seek to test this same intervention in a fully powered, 3-arm efficacy/effectiveness trial. The goal of this study is to randomize 180 smokers across three sites to test the efficacy/effectiveness of the intervention at increasing point prevalence abstinence by reducing anxiety and depression at a 1-month follow-up (the end of treatment timepoint/ approximately 1-month post quit day) and a 6-month follow-up (approximately 6-months post quit day).
This study aims to assess the effect of personalized support using instant messaging application on smoking cessation in smokers proactively recruited from smoking hotspots in Hong Kong.
