Relation between access to tobacco and adolescent smoking.

OBJECTIVE: To examine the relation between rates of sales of tobacco to minors and youth smoking prevalence. DESIGN: Repeated annual cross sectional surveys. SETTING: Seventy five communities in Oregon. PARTICIPANTS: A random sample of students in grades 8 and 11 (ages 13 and 17 years) and retail outlets in each participating community. MAIN OUTCOME MEASURES: Thirty day and daily smoking prevalence. RESULTS: The rate of illegal merchant sales in the communities was related to the smoking rate for 11th graders in those communities, but not for 8th graders. For every 10% increase in illegal sales rates there was an estimated 0.8% increase in 11th grade 30 day smoking prevalence and a 0.4% increase in daily smoking. Communities with lower illegal merchant sales rates had expanded use of social sources and reduced use of commercial sources by 11th graders, with the opposite pattern seen in 8th graders. CONCLUSIONS: There appears to be a relatively small positive linear relation between the community rate of sales to minors and 11th grade youth smoking prevalence in those communities. Youth adjust their tobacco sources depending on the level of commercial availability.

Why have we been more successful in reducing tobacco use than violent crime?

Tobacco control efforts have been associated with a significant reduction in the prevalence of tobacco use in the United States. Efforts to reduce the incidence of violent crime have been much less successful. This paper argues that progress on tobacco control stems from the existence of a clear, empirically based, and widely understood analysis of the tobacco problem that articulates (a) the harms associated with its use, (b) the causes of tobacco use, and (c) the programs and policies that could reduce tobacco use. This analysis has guided the development of a network of social organizations that have been advocating for policies and programs that are reducing tobacco use. In contrast, there is not a widely shared, cogent, and empirically based analysis of the problem of violent crime. As a result, efforts to combat violent crime are fragmented and it has proven difficult to generate support for preventive programs and policies. Substantial empirical progress has been made, however, on how violent crime could be prevented. That evidence is reviewed. It is argued that the articulation of this evidence is a critical first step for achieving widespread reduction in the incidence of violent crime. Communication of that evidence to audiences that matter will require that behavioral scientists become better organized to advocate for the adoption of empirically supported practices.

The value of interrupted time-series experiments for community intervention research.

Greater use of interrupted time-series experiments is advocated for community intervention research. Time-series designs enable the development of knowledge about the effects of community interventions and policies in circumstances in which randomized controlled trials are too expensive, premature, or simply impractical. The multiple baseline time-series design typically involves two or more communities that are repeatedly assessed, with the intervention introduced into one community at a time. It is particularly well suited to initial evaluations of community interventions and the refinement of those interventions. This paper describes the main features of multiple baseline designs and related repeated-measures time-series experiments, discusses the threats to internal validity in multiple baseline designs, and outlines techniques for statistical analyses of time-series data. Examples are given of the use of multiple baseline designs in evaluating community interventions and policy changes.

Planning and initiation of the ONDCP National Youth Anti-Drug Media Campaign.

An alarming upsurge in substance use among American youth in the past decade prompted the Office of National Drug Control Policy (ONDCP) to organize the multifaceted, primary prevention National Youth Anti-Drug Media Campaign. The campaign focuses on adolescents (especially ages 11-13 years), but also targets adolescents' parents and other influential adults. The campaign's main goal is to educate and enable American youth to reject illegal drugs. The purpose of this article is to describe the origin of campaign objectives, processes for the development of specific advertising messages to fulfill these objectives, and how the ONDCP experience could provide a model for other health-oriented media campaigns.

A randomised controlled trial of a community intervention to prevent adolescent tobacco use.

OBJECTIVE: Experimental evaluation of comprehensive community wide programme to prevent adolescent tobacco use. DESIGN: Eight pairs of small Oregon communities (population 1700 to 13 500) were randomly assigned to receive a school based prevention programme or the school based programme plus a community programme. Effects were assessed through five annual surveys (time 1-5) of seventh and ninth grade (ages 12-15 years) students. INTERVENTION: The community programme included: (a) media advocacy, (b) youth anti-tobacco activities, (c) family communications about tobacco use, and (d) reduction of youth access to tobacco. MAIN OUTCOME MEASURE: The prevalence of self reported smoking and smokeless tobacco use in the week before assessment. RESULTS: The community programme had significant effects on the prevalence of weekly cigarette use at times 2 and 5 and the effect approached significance at time 4. An effect on the slope of prevalence across time points was evident only when time 2 data points were eliminated from the analysis. The intervention affected the prevalence of smokeless tobacco among grade 9 boys at time 2. There were also significant effects on the slope of alcohol use among ninth graders and the quadratic slope of marijuana for all students. CONCLUSION: The results suggest that comprehensive community wide interventions can improve on the preventive effect of school based tobacco prevention programmes and that effective tobacco prevention may prevent other substance use.

The value of the Parenting Scale for measuring the discipline practices of parents of middle school children.

The psychometric properties of the Parenting Scale (Arnold, O'Leary, Wolff, and Acker, 1993), a 30-item instrument originally developed to assess the discipline practices of parents of preschool children, were examined for parents of middle school students. Subjects were 298 parents of middle school student identified as at-risk for problem behavior. An exploratory factor analysis identified two factors labeled 'Overreactivity' and 'Laxness', closely resembling two of the factors found by Arnold et al., but each of these factors contained only six items. Confirmatory factor analyses, using data from the first two assessments, replicated this factor structure. The factors were significantly correlated with measures of parents' behavior, with scales from the child Behavior Checklist and Parent Daily Reports, and with the Beck Depression Inventory. The Laxness factor was less robust than the Overreactivity factor.

Interpersonal skills training to reduce aggressive and delinquent behavior: limited evidence and the need for an evidence-based system of care.

The prevention of aggressive and delinquent behavior during childhood and adolescence is one of the highest priorities for public health and crime prevention. The most common approach to preventing or treating these conduct problems has been to provide interpersonal skills training to the affected youth. This paper reviews all randomized controlled trials evaluating interpersonal skills training programs as an intervention to reduce conduct problems. Research shows that such programs have weak empirical support as isolated interventions. An alternative evidence-based system of care is described. Such a system would include behavioral parent training and behavioral classroom-based interventions for young children at risk of developing problems, as well as multisystemic family therapy or multidimensional treatment foster care for chronic delinquents. Within such a network of services, interpersonal skills training could play an important supportive role. Such a system holds the greatest promise for reducing the prevalence of aggressive and delinquent behavior in communities.

Development of adolescent problem behavior.

The developmental model of adolescent antisocial behavior advanced by Patterson and colleagues (e.g., Patterson, Reid, & Dishion, 1992) appears to generalize the development of a diverse set of problem behaviors. Structural equation modeling methods were applied to 18-month longitudinal data from 523 adolescents. The problem behavior construct included substance use, antisocial behavior, academic failure, and risky sexual behavior. Families with high levels of conflict were less likely to have high levels of parent-child involvement. Such family conditions resulted in less adequate parental monitoring of adolescent behavior, making associations with deviant peers more likely. Poor parental monitoring and associations with deviant peers were strong predictors of engagement in problem behavior. These constructs accounted for 46% of the variance in problem behavior. Although association with deviant peers was the most proximal social influence on problem behavior, parental monitoring and family factors (conflict and involvement) were key parenting practices that influenced this developmental process.

The effectiveness of a parenting skills program for parents of middle school students in small communities.

This study provides evidence of the effectiveness of behaviorally based parenting skills classes provided by carefully trained and supervised group leaders who were not mental health clinicians. A program for parents of at-risk middle school students was evaluated in a randomized controlled trial in 8 small Oregon communities. Parents (N = 303) were randomly assigned to immediate treatment or a wait-list condition. Data were analyzed using latent growth modeling. Participation in the program led to significant improvements in problem-solving interactions as indicated by parent reports and a Taped Situations Test. Parents' over-reactivity and laxness toward their children's behavior were reduced and their feelings toward their children improved significantly as a function of treatment. Parent-reported child antisocial behavior was also reduced.

Parent-daughter discussions to discourage tobacco use: feasibility and content.

Parents engaged their 6th- and 8th-grade daughters in a conversation about tobacco. The parents were guided by a pamphlet designed to encourage effective family communication about tobacco. Conversations were audiotaped for later coding. Evidence is presented that such parent-daughter conversations about tobacco use can be successfully carried out in a nonaversive manner. Overall, the conversations were perceived to have gone well, with very little conflict reported. Further, the daughters reported that the parental advice was helpful and they did not resist receiving such advice. Among the topics suggested by the pamphlet, the following were most frequently discussed: consequences of smoking as experienced by friends and relatives, difficulty of quitting, promotional tactics of tobacco companies, making rules about tobacco use, and deciding on the consequences of rules adherence or violation. Other frequently discussed topics, which were not covered in the pamphlet, may also be appropriate for parent-daughter conversations: diminished physical attractiveness and body-image issues, how to resist peer pressure, and health risks.

Contributions of the social context to the development of adolescent substance use: a multivariate latent growth modeling approach.

This article demonstrates a latent growth curve methodology for analyzing longitudinal data of adolescent substance use. Hypotheses concerning the form of growth in alcohol, cigarette, and marijuana use, and covariates influencing the form of growth, were tested. Participants were male and female adolescents (n = 664) assessed at three time points. A common trajectory existed across the developmental period with significant increases in all three substances. Second-order multivariate extensions of the basic latent growth modeling framework suggested that associations among the individual differences parameters, representing growth or change in the various substance use behaviors, could be adequately modeled by a higher-order substance use construct. Inept parental monitoring, parent-child conflict, peer deviance, academic failure, gender, and age, were significant predictors of initial levels and the trajectory of substance use.

Behavioral family interventions for improving child-rearing: a review of the literature for clinicians and policy makers.

This paper reviews evidence that behavioral family interventions are effective at improving child-rearing in distressed families and families with children exhibiting disruptive behavior. Essential therapeutic strategies offered within a collaborative therapeutic process are identified. Exemplary materials for parents and clinicians are identified. Differences between behavioral family interventions and two popular press parenting approaches are highlighted, including the lack of empirical support for these widely used programs and the advice they offer which runs counter to behavioral approaches. Recommendations are offered for combining behavioral family interventions with other empirically supported approaches, promoting more widespread use of empirically supported treatments, such as behavioral family interventions, and the need for a public health perspective on family functioning, involving collaboration among clinicians, policy makers, and researchers.

Mobilizing positive reinforcement in communities to reduce youth access to tobacco.

A community intervention to mobilize positive reinforcement for not selling tobacco to young people was evaluated. The intervention had five components: (a) mobilization of community support, (b) merchant education, (c) changing consequences to clerks for selling or not selling to those under 18, (d) publicity about clerks' refusals to sell, and (e) feedback to store owners or managers about the extent of their sales to adolescents. A multiple baseline design experiment was conducted, in which two small Oregon communities received the intervention, while two other continued in baseline. Outlets' willingness to sell was assessed repeatedly by teenage volunteers. The intervention significantly reduced the proportion of stores willing to sell. Mobilizing social and material reinforcement for stores not selling tobacco to young people is a viable means of reducing such sales. It may be especially valuable in communities where laws against sales to minors go unenforced.

Experimental evaluation of a modular approach to mobilizing antitobacco influences of peers and parents.

The experimental evaluation of two components of a community intervention to prevent adolescent tobacco use are described. Youth antitobacco activities (e.g., peer quizzes, sidewalk art, poster and T-shirt giveaways, etc.) and family communications activities (pamphlets to parents and student quizzes of parents) were evaluated in two time-series experiments, each of which was conducted in two experimental and one control community. Students in Grades 6 and 8 and their parents were assessed in a series of four phone surveys in the first experiment and six phone surveys in the second. Implementation of the youth antitobacco and family communications activities led to significantly greater exposure of young people to antitobacco information. They led to increases in parent and youth knowledge about tobacco use and more negative attitudes toward tobacco. In Experiment 2, youths in intervention communities had significantly lower rated intentions to smoke. The findings suggest the value of a modular approach to community interventions for influencing the social context relevant to the onset of adolescent tobacco use.

Correlation of retinopathy of prematurity in fellow eyes in the cryotherapy for retinopathy of prematurity study. The Cryotherapy for Retinopathy of Prematurity Cooperative Group.

OBJECTIVE: To examine the similarity of extent (sectors) and severity (stage) of acute-phase retinopathy of prematurity (ROP) between fellow eyes and the concordance of cicatricial outcomes at age 1 year of eyes that did not develop threshold disease. METHODS: Four thousand ninety-nine infants with birth weights of less than 1251 g who participated in a natural history segment of the Cryotherapy for Retinopathy study underwent biweekly eye examinations from 4 to 6 weeks after birth until retinal vasculature was complete or until ROP regressed or reached threshold severity. Eyes were categorized as follows: (1) no ROP, (2) less than prethreshold ROP, (3) prethreshold ROP, (4) threshold ROP, and (5) unable to determine. The presence and stage of ROP residua in fellow eyes were evaluated at 12 months. RESULTS: Acute-phase ROP status between 32 and 42 weeks postconceptional age showed a high degree of correspondence between fellow eyes in severity (stage) and location (zone) of ROP, presence of plus disease, and sectors of stage 3 retinopathy. More variability between eyes was seen when cicatricial status at age 1 year was examined. This higher variability was evident even though results from patients with threshold ROP (many of whom underwent cryotherapy) were excluded. CONCLUSION: The usual course of ROP during its acute phase is for fellow eyes to be very similar in ROP status. However, asymmetry between eyes is not unusual in eyes with posterior pole residua of ROP.

Peer and parental influences on adolescent tobacco use.

Longitudinal models of the development of adolescent smoking and smokeless tobacco (ST) use were tested for a sample of 643 adolescents, age 14 to 17. The sample was assessed at three time points. Smoking, smokeless tobacco, and other problem behaviors formed a single problem behavior factor. Structural equation modeling indicated that inadequate parental monitoring and association with deviant peers at Time 2 predicted tobacco use at Time 3. When parental and peer smoking at Time 2 were added to the model, each accounted for significant variance in predicting Time 3 smoking, but inadequate parental monitoring and association with deviant peers still accounted for some of the variance in Time 3 smoking. In predicting boys' smokeless tobacco use, monitoring at Time 2 predicted smokeless tobacco use, but only when parental approval of ST use was not included. Fathers approval of ST use at Time 2 predicted ST use at Time 3, while maternal disapproval predicted its use.
