A process evaluation of an intervention to promote home smoking bans among low income households

Exposure to secondhand smoke occurs primarily in the home due to passage of smoke-free legislation. Creation of a total household smoking ban can reduce associated health conditions such as asthma, lung cancer, heart disease and stroke. This paper describes the results of a randomized control trial of a minimal intervention to create smoke-free homes. 2-1-1 callers were invited to participate in the trial and were randomized to an intervention (mailings and a coaching call) or a control group (no intervention). We assessed reach, dose, fidelity, and receptivity to the intervention through program records and a 3-month follow-up survey with intervention participants. For the intervention materials, materials were mailed to 244 participants (99.2%) and 227 participants (92.3%) received the coaching call intervention. 92.3% received all intervention components. Participants who had full household bans at 3 months were more likely to conduct behaviors leading to a smoke-free home (i.e., making a list of reasons, having a family talk, posting a pledge) than were those with no/partial ban. The intervention materials also were rated higher in relevance and usefulness by non-smokers than smokers. Results demonstrate that this minimal intervention had high fidelity to the delivery of components and relatively high receptivity.     

Alcohol and tobacco use among South Korean adolescents: An ecological review of the literature

This article represents a comprehensive review of the literature on the predictors, consequences and prevalence of alcohol and tobacco use among South Korean youth. A systematic review of the literature in Korean and English social science journals was undertaken. Findings suggest that processes at multiple levels may lead to problems with alcohol and tobacco among these youth. In particular, the literature suggests that risk factors at the socio-demographic (age, gender, and depression), micro- (family, peer, and teachers), meso- (relations between home and school), exo- (parent-related life events and media), macro- (parenting practices and academic stress), and chrono-systems levels (Asia-Pacific financial crisis in 1997) are associated with increased alcohol and tobacco use. Higher quality of relationships with parents, peers, and teacher can contribute to reductions in alcohol and tobacco use and may offer insights for developing prevention and treatment programs that are appropriate for this population.     

Is Early Smoking a Causal Risk Factor for Later Cognitive Impairment? A 20-year Prospective Study with Time-varying Propensity Score Matching Based on Random Intercept and Slope

Although epidemiological studies support an association between smoking and cognitive impairment, existing data do not answer the question of whether this association is causal or arises from covariates. In this paper, we investigate smoking status, assessed from adolescence to adulthood, and subsequent cognitive problems in a large representative sample of youths. To analyze this data, we propose a method for causal effects using full matching based on the subject-specific random intercept and slope of the propensity scores. The findings suggest that earlier smoking is not a causal factor for later cognitive problem (odds ratio = 1.64, 95% CI: 0.97–2.80, p = 0.06).     

Evaluating theory-based evaluation: information, norms, and adherence

Programmatic social interventions attempt to produce appropriate social-norm-guided behavior in an open environment. A marriage of applicable psychological theory, appropriate program evaluation theory, and outcome of evaluations of specific social interventions assures the acquisition of cumulative theory and the production of successful social interventions - the marriage permits us to advance knowledge by making use of both success and failures. We briefly review well-established principles within the field of program evaluation, well-established processes involved in changing social norms and social-norm adherence, the outcome of several program evaluations focusing on smoking prevention, pro-environmental behavior, and rape prevention and, using the principle of learning from our failures, examine why these programs often do not perform as expected. Finally, we discuss the promise of learning from our collective experiences to develop a cumulative science of program evaluation and to improve the performance of extant and future interventions.     

Implementation fidelity and adolescent smoking: The X:IT study—A school randomized smoking prevention trial

BackgroundAssessing the actual implementation of multi-component interventions can provide important knowledge for future interventions. Intervention components may be implemented differently, knowledge about this can provide an understanding of which components are essential and therefore must be included. The aim of this study was to examine the implementation of one, two, or all three main intervention components at the individual level and to assess the association to current smoking among 13 year-olds in the X:IT study.MethodsData stems from a cluster-randomized controlled trial in 94 Danish elementary schools (51 intervention; 43 control schools). Implementation was measured by aspects of adherence, dose, quality of delivery, and participant responsiveness based on questionnaire data from 4161 pupils at baseline (mean-age: 12.5 years) and 3764 pupils at first follow-up eight months later. Coordinator responses from 49 intervention schools were also included. Associations between individual level implementation of the three main components and pupil smoking were examined through a 3-level logistic regression model.ResultsAlthough implementation fidelity for the three main intervention components was good, only one third (38.8%) of pupils in intervention schools were exposed to full implementation of the intervention. Among these pupils odds ratio for smoking was 0.25 (95% CI: 0.15 – 0.42).ConclusionsSchool-based programs can be very effective if carefully implemented. Future school-based smoking preventive initiatives should include multiple components, and seek to enhance implementation quality of all components.     

The needs of women and their partners regarding professional smoking cessation support during pregnancy: A qualitative study

BackgroundDespite the health risks of smoking, some women continue during pregnancy. Professional smoking cessation support has shown to be effective in increasing the proportion of pregnant women who quit smoking. However, few women actually make use of professional support.AimTo investigate the needs of women and their partners for professional smoking cessation support during pregnancy.MethodsSemi-structured interviews were held with pregnant women and women who recently gave birth who smoked or quit smoking during pregnancy, and their partners, living in the north of the Netherlands. Recruitment was done via Facebook, LinkedIn, food banks, baby stores and healthcare professionals. The interviews were recorded, transcribed and thematically analysed.Results28 interviews were conducted, 23 with pregnant women and women who recently gave birth, and five with partners of the women. The following themes were identified: 1) understanding women’s needs, 2) responsibility without criticism, and 3) women and their social network. These themes reflect that women need support from an involved and understanding healthcare professional, who holds women responsible for smoking cessation but refrains from criticism. Women also prefer involvement of their social network in the professional support.ConclusionFor tailored support, the Dutch guideline for professional smoking cessation support may need some adaptations. The adaptations and recommendations, e.g. to involve women and their partners in the development of guidelines, might also be valuable for other countries. Women prefer healthcare professionals to address smoking cessation in a neutral way and to respect their autonomy in the decision to stop smoking.
