NCT ID: NCT03196102 Completed - Nicotine Dependence Clinical Trials

Evaluation of a Brief Tobacco Intervention in the US Military

Start date: April 5, 2017
Phase: N/A
Study type: Interventional

While the military has taken steps to reduce tobacco use over the past two decades, over a quarter of new military recruits report regular tobacco use prior to enlistment. This rate is higher than the national prevalence of 21.3% of US adults. Brief health prevention programs may be particularly effective for Airmen in Technical Training, given that all Airmen have been tobacco free for 11 ½ weeks and nearly 2/3rds are confident that they won't return to tobacco. We have developed and validated a Brief Tobacco Intervention (BTI) that is currently being implemented as part of Technical Training. We found that a motivational interviewing based, 40 minute BTI was efficacious in increasing perceived harm and decreasing intentions to use tobacco in a sample of 1055 Air Force trainees. Although we obtained significant positive changes in latent cognitive constructs for tobacco behavior that are highly predictive of future tobacco use in youth and young adults, the Little et al study did not obtain measures of actual tobacco resumption following the ban on tobacco in Air Force training. Given that 69.8% of all tobacco resumption/initiation occurs in Technical Training, a study that evaluates the short-term impact of our BTI on actual tobacco use is necessary prior to conducting the full scale R01 that would evaluate the long term efficacy of the BTI intervention. Thus, we propose the following Specific Aims: (1) To recruit approximately 2,000 Air Force trainees at the beginning of Technical Training at Joint Base San Antonio-Lackland Air Force in San Antonio, Texas during the 11 ½ week involuntary cessation ban; (2) To randomize participants to either (a) receive our cigarette smoking military tailored pamphlet (HL095758), The Airmen's Guide to Remaining Tobacco Free (Airmen's Guide; which has been disseminated and is now the standard of care in the Air Force) or (b) the Airmen's Guide + Brief Tobacco Intervention (BTI); (3) To determine the short-term (3 month, end of Technical Training) efficacy of the intervention on tobacco abstinence. Our primary outcome is tobacco abstinence at the end of Technical Training to determine an estimated effect size as well as establish the requisite preliminary work for a subsequent R01. Given that over 220,000 new recruits enter the military annually in one of the service branches, the public health implications of an effective brief tobacco intervention targeting the most commonly used tobacco for military personnel in Technical Training is considerable. If the BTI is proven efficacious it can be easily disseminated to other service branches that have similar tobacco bans during Technical Training.

NCT ID: NCT03194958 Completed - Smoking Cessation Clinical Trials

Helping Poor Smokers Quit

Start date: June 5, 2017
Phase: N/A
Study type: Interventional

Using a 2x2 randomized factorial design, we will conduct a statewide field trial in Missouri to compare the relative and combined effects of these two strategies for augmenting an existing, evidence-based tobacco quitline program. Among 2000 low-income smokers, half will receive standard Missouri quitline services and half will receive new Specialized Quitline services targeted to this group. In each of these groups, half also will receive calls from a trained navigator to help them address unmet Basic Needs and the accompanying psychological distress that act as barriers to smoking cessation.

NCT ID: NCT03151421 Completed - Tobacco Use Clinical Trials

Air Quality Feedback to Reduce Second-hand Smoke (SHS) Exposure in the Home

TackSHSWP4
Start date: September 1, 2016
Phase: N/A
Study type: Interventional

This is a European study which is part of a larger research project (The TackSHS project) funded by the European Union's Horizon 2020 Research and Innovation Programme (Grant Agreement No 681040) and led by the Catalan Institute of Oncology. This study will examine the efficacy of using personalised air quality measurements in homes of smokers to encourage behaviour-change towards having a smoke-free home environment. Building on recent quantitative and qualitative work showing that feedback of second-hand smoke (SHS) measurement information can help motivate smokers to change their behaviour. This study will develop a targeted intervention for use with socio-economically deprived smokers in four countries (Scotland, Spain, Greece, Italy) across the EU. Two-hundred smokers (50 in each country) will be recruited and offered low-cost, simple to operate particle counting instruments to measure and log SHS levels in their home for a period of 30 days. During this time near real-time, personalised feedback will be provided to, and discussed with, the smoker along with target-setting and exploration of suitable methods of behaviour-change. Feedback will be given via text message to mobile phones, emails and personal voice calls. A final visit will gather data on changes made while a proportion of participants (10-20%) in each country will take part in a further qualitative interview by phone to gather data on their experience of the intervention. Study outcomes will include quantitative measures such as changes in average and maximum fine particulate matter (PM2.5) concentrations and self-declared household smoking rules, while qualitative data will be gathered using questionnaire and interview to explore what elements of the intervention were useful/unhelpful, particularly well/poorly understood, and what were the barriers for those who did not make changes. This WP will provide a comprehensive database of baseline measurements of SHS concentrations in home settings from across the EU with the potential to generate over 8 million minutes of measurements of household air quality. Analysis of the differences by country and possible determinants of exposure will be carried out.

NCT ID: NCT03111537 Completed - Tobacco Smoking Clinical Trials

Methods Project 4: Clinical Trial - Amended

COMET
Start date: May 2015
Phase: N/A
Study type: Interventional

Cigarette smokers will be randomized to E-cigarette, Nicotine Gum or Lozenge, or Control Group. Participants will enter a 1 week sampling phase. Smokers interested in continuing with the study after the sampling phase will undergo a 2 week baseline assessment phase and will then enter an 8 week intervention. Tobacco use patterns, subjective responses to product, and nicotine and toxicant exposure will be assessed.

NCT ID: NCT03099811 Completed - Asthma Clinical Trials

Financial Incentives to Reduce Pediatric Tobacco Smoke Exposures

Start date: June 1, 2017
Phase: N/A
Study type: Interventional

Secondhand smoke exposure (SHSe) is one of the most common and potentially modifiable environmental triggers for asthma. Financial incentivization may serve as an effective modality to reduce SHSe among pediatric asthmatics with potential down-stream benefits on improved asthma control and subsequent reduced healthcare utilization. This study plans on testing the feasibility and effectiveness of financial incentives to decrease SHSe, derived from primary caregivers and a member of their social network, of children with persistent asthma.

NCT ID: NCT03062709 Completed - Asthma Clinical Trials

A Study of Tobacco Smoke and Children With Respiratory Illnesses

Start date: March 12, 2017
Phase: N/A
Study type: Interventional

This study aims to assess the feasibility of using an intervention for environmental smoke exposure in children that uses cotinine testing results with written materials and telephone counseling for a potential future study of parents whose children are admitted with respiratory illnesses to The Barbara Bush Children's Hospital in Portland, Maine.

NCT ID: NCT03058991 Completed - Tobacco Smoking Clinical Trials

Cognitive and Emotional Skills to Aid Smoking Prevention

DOAN
Start date: November 8, 2016
Phase: N/A
Study type: Interventional

The purpose of the current proposal is to investigate the extent to which interventions designed to improve cognitive (working memory) and emotional (distress tolerance) regulatory processes enhance the effectiveness of standard no-smoking informational interventions. Emotional and cognitive dysregulation increases the likelihood of smoking and makes it particularly challenging to benefit from standard interventions. Working memory and associated deficits make it more difficult for individuals to utilize information from interventions, make judicious decisions regarding the cost and benefits of smoking, and to resist targeted advertising. In addition, disruptions in emotion regulatory capacities increase the probability of using cigarettes as a coping mechanism to self-regulate negative affect and stress. Individuals with affective disturbances smoke at higher rates and have more difficulties quitting, and are more likely to smoke as a way to reduce negative affect. The goal of the current project is to generate new insights and new approaches to smoking prevention among low-SES youth by investigating (1) the influence of known SES-related deficits in working memory and affect regulation on proximal measures of smoking risk, and (2) the potential for targeted interventions to reverse these risks. Specifically, the investigators examine the influence of working memory training and distress tolerance (mindfulness) interventions on cognitive/affective targets placing individuals at risk for smoking initiation and maintenance. The specific aims of this study are therefore to investigate: 1. The feasibility and acceptability of school- and community-based brief interventions targeting working memory and distress tolerance in a diverse sample of low SES adolescents. 2. The effects of working memory and distress tolerance interventions, relative to a standard informational intervention alone, on specific cognitive-affective targets-delay discounting and distress tolerance--relevant to cigarette smoking initiation and maintenance. 3. The impact of cognitive /affective target activation on proximal measures of smoking risk/behavior and related health outcomes following intervention.

NCT ID: NCT03047967 Completed - Pregnancy Related Clinical Trials

Effects of Prenatal Tobacco Smoke Exposure on Lung Function and Respiratory Epithelium Functionality in Newborns

Start date: November 10, 2017
Phase: N/A
Study type: Interventional

Despite public campaigns to prevent cigarette smoking, it's about 20% of women who keep on smoking during pregnancy, exposing their fetus to prenatal tobacco adverse effects. Although environnemental tobacco smoke exposure effects are well known, consequences of prenatal tobacco smoke exposure (PTSE) need better caracterization. Previous animal study from our group have shown, in prenatal nicotine exposed mouse pups, alterations in tracheal epithelial structure similar to those observed in KO α7-nAChR mouse pups. These findings support the hypothesis that α7-nAChR are involved in the process of deleterious effects of tobacco smoking on respiratory epithelium development. The purpose of the present clinical study is to compare PTSE neonates with controls according to lung function and respiratory epithelial functionality. At the age of 3 days, small respiratory epithelium fragments will be obtained from gentle nasal brushing performed under antalgic premedication according to the method we previously published. Epithelium samples will be used for in vitro studies of α7-nAChR and CFTR functionality. Between the ages of 2 and 6 weeks, lung function testing will be performed, by means of baby-body plethysmography.

NCT ID: NCT03015597 Completed - Smoking Cessation Clinical Trials

Pilot Study of Contingency Management for Smoking Cessation

Start date: October 2016
Phase: N/A
Study type: Interventional

The purpose of this study is to see whether contingency management (CM) can be successfully added as an adjunct treatment to standard stop smoking services in outpatients undergoing treatment for opiate addiction. Forty tobacco smoking patients undergoing treatment for opiate addiction will be stratified to a CM intervention for either smoking abstinence or attendance at the clinic, whilst also receiving usual stop smoking services cessation treatment. The intervention will run for five weeks and participants will be followed up six months after the beginning of the study.

NCT ID: NCT02968381 Completed - Smoking Cessation Clinical Trials

A Guided Imagery Tobacco Cessation Intervention Delivered by a Quit Line and Website

QLImagery
Start date: May 1, 2018
Phase: N/A
Study type: Interventional

Tobacco use is still the leading cause of preventable disease and death in the United States. Tobacco quit lines are effective at helping smokers to quit, but quit lines are underutilized, especially by men and racial/ethnic minorities. Guided imagery is effective at helping people quit smoking, and is appealing to males and diverse racial groups, but has limited reach. The proposed study will develop and test the feasibility and acceptability of a guided imagery tobacco cessation intervention that is delivered by a combination of quit line coaches and an interactive website. The investigators hypothesize that guided mental imagery delivered using the quit line "coaching model" combined with an interactive website could be an effective intervention strategy.
