Policy and Practice Changes Associated with a Tobacco-Free Initiative in Residential Substance Use Disorder Treatment
A California-sponsored, 18-month, tobacco-free intervention in residential substance use disorder (SUD) programs was associated with increases in tobacco-free grounds and tobacco-related client services. The current study examined whether positive results would be replicated in 11 programs participating subsequently. Program directors ( N = 11) completed surveys of tobacco-related policies pre- and post-intervention. Pre- ( n = 163) and post-inte…
Smoking Behavior and Wellness among Individuals in Substance Use Disorder Treatment
Tobacco-related morbidity and mortality disproportionately affect people with substance use disorders (SUD). Encouraging overall wellness may support tobacco use cessation. We investigated relationships between wellness (health status, physical activity, sugar-sweetened beverage (SSB) consumption), cigarette smoking, and smoking cessation among SUD treatment patients to inform clinical care. Cross-sectional surveys were conducted with 395 patient…
Effects of Social Media on Adolescents’ Willingness and Intention to Use E-Cigarettes
INTRODUCTION: This study examined the effects of experimentally manipulated social media exposure on adolescents' willingness and intention to use e-cigarettes. AIMS AND METHODS: Participants were 135 adolescents of age 13-18 (52.6% female, mean age = 15.3) in California. Participants viewed six social media posts online in a 2 (post source: peer or advertisement) × 2 (e-cigarette content exposure: heavy or light) between-subjects design. Analyse…
Practitioner’s Guide to Latent Class Analysis
Latent class analysis is a probabilistic modeling algorithm that allows clustering of data and statistical inference. There has been a recent upsurge in the application of latent class analysis in the fields of critical care, respiratory medicine, and beyond. In this review, we present a brief overview of the principles behind latent class analysis. Furthermore, in a stepwise manner, we outline the key processes necessary to perform latent class …
Measures of both perceived general and specific risks and benefits differentially predict adolescent and young adult tobacco and marijuana use
Health behavior theorists and prevention researchers use a variety of measures of adolescent and young adult (AYA) risk and benefit perceptions to predict tobacco-use and marijuana-use behaviors. However, studies have not examined whether and how perception measures that ask about likelihood of more general outcomes such as “harm” versus ask about specific risk or benefit outcomes compare or whether they differentially predict AYA willingness to …
Homeless women's perspectives on smoking and smoking cessation programs
Racial/Ethnic Differences in Tobacco Use and Cessation Services among Individuals in Substance Use Treatment
Few studies explore racial/ethnic disparities in tobacco use and access to cessation services among people with substance use disorders (SUD). We collected data from Hispanics ( n = 255), non-Hispanic Whites ( n = 195), and non-Hispanic Blacks ( n = 126) across 24 Californian residential SUD treatment programs. Data were analyzed via regression models adjusting for demographics, cigarettes per day, past quit attempts, intent to quit in the next 3…
Menthol cigarette use in substance use disorder treatment before and after implementation of a county-wide flavoured tobacco ban
In subgroups where smoking has remained elevated, like those receiving SUD treatment, local menthol bans may have only modest impacts on smoking behaviour. Broader regional, state or national bans, that effectively restrict access to menthol products, may be needed to show stronger effects on smoking behaviour
State Policies Targeting Alcohol Use during Pregnancy and Alcohol Use among Pregnant Women 1985–2016
Differential Effects of Pregnancy-Specific Alcohol Policies on Drinking Among Pregnant Women by Race/Ethnicity
Purpose: Alcohol use during pregnancy is a significant public health concern. Nearly all U.S. states have enacted policies targeting alcohol use during pregnancy, but there has been little research examining their impact, particularly across racial/ethnic groups. Methods: Using data from the Behavioral Risk Factor Surveillance System and about eight state-level, pregnancy-specific alcohol policies from 1985 to 2016, the aim of this study was to e…

The Association Between Psychiatric Disorders and Telomere Length
Do cigarette graphic warnings encourage smokers to attend a smoking cessation programme
Smokers who received GWLs on their cigarette packs were more likely to attend a cessation programme. Thus, this study is one of the first to document a change in a directly observed behavioural outcome as a function of month-long exposure to cigarette pack GWLs

Mapping Engagement in Twitter-Based Support Networks for Adult Smoking Cessation
We examined engagement in novel quit-smoking private social support networks on Twitter, January 2012 to April 2014. We mapped communication patterns within 8 networks of adult smokers (n = 160) with network ties defined by participants’ tweets over 3 time intervals, and examined tie reciprocity, tie strength, in-degree centrality (popularity), 3-person triangles, 4-person cliques, network density, and abstinence status. On average, more than 50%…

An elevated prevalence of menthol use was found among persons with severe psychological distress, suggesting another group that could potentially benefit from the regulation of menthol cigarettes
Global Reach of an Internet Smoking Cessation Intervention among Spanish- and English-Speaking Smokers from 157 Countries
This investigation is a secondary analysis of demographic, smoking, and depression information in a global sample of Spanish- and English-speaking smokers who participated in a series of randomized controlled smoking cessation trials conducted via the Internet. The final sample consisted of 17,579 smokers from 157 countries. Smoking profiles were similar across languages and world regions and consistent with characteristics of participants in tra…
Creating classrooms that students experience as communities
Although prior research has shown sense of community in schools to be related to many positive student characteristics, effective interventions that can create or enhance this sense have not been demonstrated. In this paper we describe a comprehensive elementary school program, implemented by teachers, that was successful in creating a sense of community in the classrooms, as perceived by students. The program was implemented in three elementary …
The use and misuse of chi-square
proper use of Karl Pearson's chi-square for the analysis of contingency tables is reviewed. 1949 article by Lewis and Burke, who cited nine sources of error in the use of chi-square, is updated. Research on the application of the chi-square statistic is examined and supplementary and alternative approaches are discussed. Emphasis is placed on techniques that are of use to the practicing researcher who often deals with qualitative ordered and unor…
Enhancing Children’s Prosocial Behavior in the Classroom
A program designed to enhance children’s prosocial development was conducted in three suburban elementary schools for 5 consecutive years, focusing primarily on a single cohort of children as it moved from kindergarten through fourth grade. Repeated observations were conducted each year to assess program implementation and student interpersonal behavior in classrooms in the three “program” schools and in three “comparison” schools. Analyses of th…
