Self-initiated quitting among adolescent smokers

A content analysis of smartphone apps for adolescent smoking cessation

Adolescent cigarette smokers have an increased risk of sustained smoking into adulthood. Smartphone applications (apps) for smoking cessation are a promising treatment resource. However, research on apps for adolescent smoking cessation is limited. This study compared smoking cessation mobile apps targeting an adolescent audience with popular cessation apps for a general audience. Adolescent and general-audience apps were identified by searching the Google Play and Apple App Stores (November 2016). Two coders assessed each app for adherence to clinical practice guidelines for tobacco and adolescent-specific content (2016-2017) and developed a summary score that summed all adherence and adolescent content criteria. Eight adolescent apps were identified and compared with the top 38 general apps (as ranked by Apple and Google). Both general and adolescent apps commonly had adherence content related to developing a quit plan (general: 73.68 per cent; adolescent: 87.50 per cent) and enhancing motivation by describing the rewards of not smoking (general: 76.32 per cent; adolescent: 62.50 per cent). Adolescent-specific content such as peer influence on smoking was common in adolescent apps but not in general apps (general: 5.26 per cent; adolescent: 62.50 per cent). Adolescent apps had a higher general adherence content summary score [t (44) = 2.55, p = .01] and a higher adolescent content summary score [t (7.81) = 2.47, p = .04] than the general apps. On average, adolescent cessation apps included more adherence content and adolescent-specific content than general apps. Future research is needed to determine the extent to which adolescents engage with the adherence content available in these apps.

Experimentation with tobacco during adolescence as a factor influencing treatment of smoking in adulthood. A retrospective cohort

BACKGROUND

There are still few studies on predictors of smoking cessation in Brazilian samples. Experimentation with tobacco during adolescence (ETA) may be one of the important predictors.

OBJECTIVE

This study aimed, within the context of a treatment-seeking group of subjects, to test the hypothesis that ETA negatively affects the outcome of smoking cessation during adulthood.

DESIGN AND SETTING

Retrospective (historic) cohort study conducted at a psychosocial care center in São Paulo, Brazil, between 2007 and 2010.

METHODS

Data on sociodemographics, smoking and medical profiles were obtained through self-report questionnaires that were completed at the baseline and at any follow-up appointment. Logistic regression models were constructed to describe factors associated with the outcome of smoking cessation, measured according to the self-reported four-week success rate among 367 outpatient smokers.

RESULTS

ETA was found to be associated with not quitting smoking through the treatment (odds ratio = 0.57; 95% confidence interval = 0.33-0.96; P < 0.05), even after adjustment for dependence level, sociodemographics, nicotine patch use and number of years of smoking.

CONCLUSIONS

Early exposure to nicotine may lead to higher risk of continuing smoking after treatment, in adulthood.

Perceived stress and poly-tobacco product use across adolescence: Patterns of association and gender differences

Perceived stress-an endophenotype indicative of the tendency to appraise stress as frequent, unpredictable and unmanageable-is associated with adolescent cigarette smoking. It is unclear whether this association: (1) extends to alternative tobacco products, like electronic cigarettes and hookah (tobacco water pipe), which are increasingly popular among youth, and (2) differs by gender. In this report, data were drawn from a population-based longitudinal cohort of youth in Southern California. Perceived stress was assessed at baseline (7th or 8th grade; 2010). Electronic cigarette, hookah, combustible cigarette, and cigar use were assessed at a 4-year follow-up (11th or 12th grade; 2014). After adjusting for confounders, polytomous logistic regressions showed that a standardized baseline perceived stress score (M = 0, SD = 1) predicted electronic cigarette, hookah, combustible cigarette, and cigar use and a poly-tobacco use index at the 4-year follow-up in the overall sample. Interactions between perceived stress and gender were also observed (Interaction Ps < 0.05), which demonstrated that the association of perceived stress with tobacco product use and poly-use were stronger in females (ORs for current use range: 1.47 to 1.72) than males (ORs range: 0.93 to 1.31). Adjusting for baseline perceived stress, the change in perceived stress from baseline to follow-up was also positively associated with use and poly-use of most tobacco products in females and in males to some extent. In the current era in which teen use of alternative tobacco products is increasingly common, adolescent tobacco use and poly-use research and prevention strategies should address gender-specific origins of tobacco product use risk and consider perceived stress and other emotional endophenotypes in such risk pathways.

Self-Initiated Cessation from Substance Use: A Longitudinal Study of the Relationship between Postulated Mediators and Quitting

This study examines psychosocial predictors of self-initiated substance use cessation among youths who have had recent substance use experience. Variables included those that are the focus of many primary prevention programs. Middle school and high school students who used either alcohol, cigarettes, smokeless tobacco, marijuana, or inhalants were surveyed on two occasions, one year separating the pretest and posttest. Pretest differences distinguished those who would quit versus those who would continue using alcohol, tobacco, and marijuana, but not inhalants. The largest pretest differences were youths' normative beliefs, manifest commitments to not use substances, and perceived incongruence between drug use and their desired lifestyles. Those who continued to use had scale values for most mediators that continued to worsen in programmatic terms, whereas measures among those who quit significantly improved. School-aged users may benefit from programs that target some of the same mediators currently promoted as effective in primary prevention programs.

Development and validation of a smoking expectancies measure for adolescents seeking to quit smoking

BACKGROUND

A more comprehensive understanding of factors that affect smoking cessation outcomes among adolescents may help enhance treatment interventions. One promising but underexplored factor that may influence cessation success is teens' specific expectancies or beliefs about smoking outcomes. The present study evaluated the validity and reliability of a new measure of expectancies and its association with cessation outcomes among 762 adolescent smokers participating in studies of the American Lung Association's Not On Tobacco cessation program.

METHODS

Self-report questionnaires were collected prior to and following participation in a smoking cessation program. Self-reported cigarette use was verified with expired-air carbon monoxide. A multistep exploratory and confirmatory factor analysis and reliability and validity analyses were performed.

RESULTS

Four theoretically related yet empirically independent factors were identified by the Smoking Expectancies Questionnaire (SEQ): (1) Positive Reinforcement, (2) Negative Reinforcement-Emotional Regulation, (3) Negative Reinforcement-Addiction and Withdrawal, and (4) Negative Outcomes/Risk. These factors could be subsumed by a single SEQ factor that reflected an overall concept of smoking expectancies relevant for adolescent smoking cessation. An overall SEQ Function score reflecting the balance between positive and negative expectancies predicted both preintervention cigarettes per day and cessation outcomes.

CONCLUSIONS

A single, overall SEQ Function score may prove useful for understanding the associations among individual, social, and contextual factors in predicting treatment outcomes. Additionally, study findings may assist with modifying smoking expectancies among cessation program participants, thereby enhancing treatment outcomes with diverse youth smoking populations.

Adolescents' movement towards cessation of smoking: role and relative value of the processes of change and nicotine dependence

The present study addresses the applicability of the Transtheoretical Model's processes of change in explaining adolescents' readiness to quit smoking. Furthermore, the association between nicotine dependence and readiness to quit was assessed both directly, as well as indirectly through the processes of change. A cross-sectional survey was conducted, identifying 1547 weekly smokers aged 14-18 years. Structural equation modelling showed that the processes of change were only marginally associated with readiness to quit. Adding nicotine dependence to the model showed a direct association between nicotine dependence and readiness to quit. Only one process of change, self-liberation (i.e. choice/commitment to change and belief in the ability to change), was found to mediate this association. Nicotine dependence appeared to be highly important in adolescents' readiness to quit.

Experience of a smoking cessation program among high school students in Taiwan

In Taiwan, the prevalence of smoking among teenagers has led to a required smoking cessation program in schools. Students caught smoking in school are required to participate in a weekly smoking cessation class. The purpose of this study was to explore the experience of high school students in a smoking cessation program. Fifteen adolescents participated in a one-on-one in-depth semistructured interview, and the content was analyzed for patterns based on the methods of Miles and Huberman. In addition, Lewin's change theory of drive forces and restraining forces was used to describe the change in behavior as a result of the program. Five major themes were identified: the onset of smoking-change influenced by families and friends; intention to quit smoking-driving force; the irresistible temptation to smoke-restraining force; limited change effects-more attention and assistance needed; and change in attitude rather than behavior-smoking remained unchanged. Changes were seen in the perceptions and attitudes of these students toward smoking at the end of the program; however, none of them were able to really quit. Most participants revealed that they used improper means to pass the carbon monoxide test requirement that was used as a measure of not smoking. Alternative future intervention strategies for further study include change in health policy to support nicotine replacement methods for heavy adolescent smoker, use of teacher support, and exercise programs to support students going through the smoking cessation period.

Sex specific trajectories in cigarette smoking behaviors among students participating in the unplugged school-based randomized control trial for substance use prevention

OBJECTIVES

Understanding the developmental pathways and sex differences in cigarette smoking behaviors in adolescents has the potential to positively impact substance abuse prevention and to reduce smoking-related health problems. Using data from the Unplugged school-based prevention trial, we investigated different patterns of smoking behavior development among secondary school students in the Czech Republic.

METHODS

Growth mixture modeling was used to examine different trajectories in cigarette smoking behaviors among male and female students (N=1874 6th graders; 50.4% male, mean age 11.8 years at baseline) participating in the Unplugged school-based randomized control trial for substance use prevention.

RESULTS

A two-class model characterized cigarette use as a function of sex and Unplugged intervention status. More rapid cigarette use increases were observed in females (OR=1.17, p=0.01 in both rapid/moderate and slow smoking escalator classes) as compared to males. Further, in both classes, more rapid increases in smoking were observed for the control group as compared to the intervention group (OR=1.22, p<0.01 slow escalators; OR=1.54, p=0.08 rapid/moderate escalators). There was no difference in sex distribution when comparing the two classes (OR=1.02, p=0.98).

CONCLUSIONS

This study adds to a growing literature on developmental and sex differences in cigarette use among adolescents. This research supports additional multi-year prevention strategies aimed at adolescent females and early treatment programs for adolescent smokers to prevent increasing cigarette use with age.

Health behaviors and mental health of students attending alternative high schools: a review of the research literature

PURPOSE

The purpose of this review is to describe current knowledge about health-risk behaviors and mental health among alternative high school students.

CONCLUSIONS

Substance use, diet and/or physical activity, sexual-risk behaviors, mental health, and violence were reviewed. Students were described as marginalized youth facing significant social environmental challenges. Findings from 43 studies published from 1997-2010 suggested a high prevalence of health-risk behaviors among alternative high school students. Very few studies were conducted by nurse researchers. Suggestions for future research include addressing social environmental factors, resiliency, and emotional/mental health outcomes.

PRACTICE IMPLICATIONS

Alternative high schools offer a venue to conduct research and implement nursing interventions with high-risk, yet resilient, youth.

The development of an adolescent smoking cessation intervention--an Intervention Mapping approach to planning

The objective of this project was to develop a theory- and evidence-based adolescent smoking cessation intervention using both new and existing materials. We used the Intervention Mapping framework for planning health promotion programmes. Based on a needs assessment, we identified important and changeable determinants of cessation behaviour, specified change objectives for the intervention programme, selected theoretical change methods for accomplishing intervention objectives and finally operationalized change methods into practical intervention strategies. We found that guided practice, modelling, self-monitoring, coping planning, consciousness raising, dramatic relief and decisional balance were suitable methods for adolescent smoking cessation. We selected behavioural journalism, guided practice and Motivational Interviewing as strategies in our intervention. Intervention Mapping helped us to develop as systematic adolescent smoking cessation intervention with a clear link between behavioural goals, theoretical methods, practical strategies and materials and with a strong focus on implementation and recruitment. This paper does not present evaluation data.

Waterpipe smoking among students in one US university: predictors of an intention to quit

OBJECTIVE

To examine the intention to quit waterpipe smoking among college students.

PARTICIPANTS

A total of 276 University of Houston students identified through an online survey administered in February 2011. Participants indicated they had smoked a waterpipe in the month prior to the survey.

METHODS

Cross-sectional study. Questions included demographics, tobacco use, perceived risk of waterpipe smoking, and social acceptability. Multivariate logistic regression was used to determine predictors of an intention to quit.

RESULTS

Most of the sample participants (n = 227; 83%) reported that they had no intention to quit. Students believing that waterpipe smoking was harmful were more likely to have an intention to quit (odd ratio [OR] = 2.38, 95% confidence interval [CI; 1.05, 5.36]). Those who smoked for more than 60 minutes were less likely to have a desire to quit (OR = 0.29, 95% CI [0.12, 0.73]).

CONCLUSIONS

The low level of a desire to quit demonstrated underscores the urgent need to develop interventions that educate users about expected harms of continued use.

How Distinct are the Stages of Change for Smoking Cessation? A Comparison of the Stages of Change and the Contemplation Ladder Using an Adolescent Sample

The stage of change approach to smoking cessation posits that smokers can be divided into categories based on the extent to which they are motivated to quit smoking. Recent research, however, suggests that the stage of change algorithm systematically misclassifies smokers by underestimating motivation to quit. The hypothesis of the current study was that the systematic misclassification by the stages of change results in stages that blend together smokers varying widely in motivation to quit. We tested this hypothesis by contrasting the stages of change with the contemplation ladder (an alternative measure of motivation to quit smoking) using cross-sectional data on ten cessation-relevant variables. The sample consisted of 401 adolescent smokers. The results were consistent with the hypothesis. The cross-sectional analyses indicated that the contemplation ladder is a more discriminating measure of motivation to quit, and that the stage of change algorithm is an unnecessarily imprecise instrument.

The relative role of nicotine dependence and smoking-related cognitions in adolescents' process of smoking cessation

The present study evaluates the role of distinct components of nicotine dependence (craving, withdrawal, behavioural dependence) in comparison to smoking-related cognitions (attitudes, perceived social approval, self-efficacy) in adolescent smoking cessation. In the process towards smoking cessation, we distinguish between distinct behavioural transitions, respectively, short-term abstinence, reduction in smoking behaviour and prolonged cessation, to evaluate differences in cessation-related antecedents as a function of varying behavioural outcomes. A total of 850 adolescent smokers (age 14-16) participated in the present study. Smoking behaviour was assessed 1 year after baseline. Results showed that all dependence components had a distinct role in the prediction of behavioural change towards cessation. Furthermore, each behavioural transition was predicted by a distinct set of variables, indicating that contributions of cessation-related factors vary across the course towards cessation. Overall, our findings suggest that smoking-related cognitions are particularly relevant in the initiation of behavioural change, such as short-term abstinence, whereas nicotine dependence, craving in particular, becomes increasingly important in the prediction of maintained behavioural change, such as prolonged cessation. Implications encompass enhanced attention to the multidimensional nature of nicotine dependence and the value of comparing different behavioural outcomes in a comprehensive understanding of cessation-related factors.

State-level tobacco control policies and youth smoking cessation measures

OBJECTIVE

Research on the effects of state-level tobacco control policies targeted at youth has been mixed, with little on the effects of these policies and youth smoking cessation. This study explored the association between state-level tobacco control policies and youth smoking cessation behaviors from 1991 to 2006.

METHODS

The study design was a population-based, nested survey of students within states. Study participants were 8th, 10th, and 12th graders who reported smoking "regularly in the past" or "regularly now" from the Monitoring the Future study. Main cessation outcome measures were: any quit attempt; want to quit; non-continuation of smoking; and discontinuation of smoking.

RESULTS

Results showed that cigarette price was positively associated with a majority of cessation-related measures among high school smokers. Strength of sales to minors' laws was also associated with adolescent non-continuation of smoking among 10th and 12th graders.

CONCLUSIONS

Findings suggest that increasing cigarette price can encourage cessation-related behaviors among high school smokers. Evidence-based policy, such as tax increases on tobacco products, should be included as an important part of comprehensive tobacco control policy, which can have a positive effect on decreasing smoking prevalence and increasing smoking cessation among youth.

Predictors of intention to quit smoking in Hong Kong secondary school children

BACKGROUND

Behavioral theories suggest that a past quit attempt influences psycho-social determinants to predict smokers' intention to quit, although no study has tested the hypothesis among youth smokers.

METHODS

A sample of 1561 Chinese secondary students, who were current smokers, were collected in a cross-sectional school-based survey in Hong Kong.

RESULTS

For the 943 students with past quit attempts, those with lower daily cigarette consumption; who perceived smoking would not elicit positive social responses from others; who had one parent/teacher who prohibited them to smoke; who were aware of the health hazards of smoking and being male smokers, were more likely to have an intention to quit smoking. For the 618 students without a past quit attempt, those who did not perceive any benefit from smoking; who had parents and teachers to prohibit them to smoke and who received social support to quit, were more likely to have an intention to quit smoking.

CONCLUSION

Strengthening the prohibition of smoking and providing social support may help initiate the intention to quit among youth smokers without a past quit attempt, while de-normalizing social images of smoking, providing information about the health hazards of smoking and relieving nicotine addiction may sustain quitting intentions among youth smokers with past quit attempts.

Key factors in smoking cessation intervention among 15-16-year-olds

The authors aimed to investigate factors associated with smoking cessation among adolescents after tobacco intervention. They examined smokers (n = 127) from one birth cohort (n = 545) in the city of Kotka in Finland. These smokers were randomized in 3 intervention groups the dentist (n = 44) and the school nurse (n = 42 groups), and a control group (n = 39). After 2 months, the authors sent a follow-up questionnaire to the initial smokers to find out who had quit.The authors found that those whose best friend was a nonsmoker were more likely to stop smoking (relative risk RR 7.0 95% Cl 4.6-10.7). Moreover, the nicotine-dependent participants (measured according to the Fagerström Test for Nicotine Dependence(36)) were less likely to stop (RR 0.1 95% Cl 0.08-0.11) compared to non-nicotine dependent participants. Last, of the diurnal types, the morning types found it easier to quit smoking than the evening types (RR 2.2 95% Cl 1.4-3.6). Thus, the authors concluded that the best friend''s influence, nicotine dependence, and diurnal type could be taken more into account in individual counseling on smoking cessation.

Examination of a Process Model of Adolescent Smoking Self-Change Efforts in Relation to Gender

Little information describes how adolescents change their smoking behavior. This study investigated the role of gender in the relationship of motivation and cognitive variables with adolescent smoking self-change efforts. Self-report and semi-structured interview data from a prospective study of smoking self-change efforts were examined among 98 adolescent smokers ages 14-18 (55% female). Social disapproval motives and short-term consequence reasons for quitting, quit self-efficacy and intentions to quit were modeled in relation to prospective self-quit attempts assessed at a 6-month follow-up, separately by gender. Hypothesized mediating relationships were not supported although gender differences were noted. Social influence motives related to intention to quit and prospective self-quit attempts among girls. For boys, intention to quit predicted making a self-quit attempt. Findings emphasize the importance of examining adolescent models separately by gender and contribute to understanding of mechanisms involved in adolescent smoking change efforts.

Smoking cessation for adolescents: a review of pharmacological and psychosocial treatments

Unlike the vast literature on smoking cessation in adults, research in adolescents has gained significant attention only within the last decade. Even with this increase in focus, research into pharmacological aids for smoking cessation in adolescents (e.g., nicotine replacement therapy, bupropion) is a more recent phenomenon and has produced only modest results. While more extensive, much of the research on behaviorally- or psychosocially-based adolescent smoking cessation interventions has been limited by a lack of control for contact time, biochemical verification of self-reported abstinence, and/or a theoretical focus for the interventions. The MEDLINE, PubMed, PSYCInfo, EMBASE, ERIC, CINHAL, Cochrane CENTRAL and Systematic Review databases were searched for articles relevant to adolescent smoking cessation treatment. After briefly examining the adolescent smoking cessation research prior to 2000, more recent developments in pharmacological aids and psychological treatment will be reviewed. Investigations have made progress in elucidating efficacious treatments for adolescent smokers, but much work remains to be done in both pharmacological and non-pharmacological areas of treatment. With the current state of the literature as a guide, future directions for research into smoking cessation for adolescents will be proposed.

Coping with temptations and adolescent smoking cessation: an initial investigation

INTRODUCTION

Although a great deal of research focuses on adolescent cigarette smoking, little is known about the process by which adolescents attempt to stop smoking. Resisting temptations to smoke is one of the key challenges encountered by individuals who attempt smoking cessation. A large body of literature has examined coping with temptation among adult smokers, and research on this issue for adolescents is lacking. To further our understanding in this area, the present study reports on an initial examination of the Smoking Temptation Coping Questionnaire (STCQ). The STCQ, which assesses coping in a social pressure situation involving cigarettes, was adapted from the Temptation Coping Questionnaire, a brief self-report measure of adolescent coping with temptations to use alcohol and other drugs.

METHODS

The present study included 109 adolescent participants (aged 14-19 years) in a naturalistic study of smoking self-change. Participants completed baseline and 6-month follow-up interviews.

RESULTS

Exploratory factor analysis of the STCQ coping scale yielded a single factor including six strategies for coping with temptations. Analyses provided support for the concurrent, predictive, and construct validity of the STCQ. In particular, the coping scale score significantly predicted prospective duration of abstinence for adolescents who engaged in smoking cessation efforts.

DISCUSSION

These results provide preliminary support for the utility of the STCQ. In addition, findings support the role of temptation coping in the adolescent smoking cessation process.

Internally-developed teen smoking cessation programs: characterizing the unique features of programs developed by community-based organizations

We have compared the unique features of teen tobacco cessation programs developed internally by community-based organizations (N=75) to prepackaged programs disseminated nationally (N=234) to expand our knowledge of treatment options for teen smokers. Internally-developed programs were more likely offered in response to the sponsoring organization’s initiative (OR=2.16, p<0.05); had fewer trained cessation counselors (OR=0.31, p<0.01); and were more likely found in urban areas (OR=2.89, p=0.01). Internally-developed programs more often provided other substance-abuse treatment services than prepackaged programs and addressed other youth-specific problem behaviors (p≤0.05). Studies that examine the effectiveness of internally-developed programs in reducing smoking and maintaining cessation for teen smokers are warranted.

Examining unsupervised time with peers and the role of association with delinquent peers on adolescent smoking

INTRODUCTION

This study explored the association between unsupervised time with peers and adolescent smoking behavior both directly and indirectly through interaction with delinquent peers, social expectancies about cigarette smoking, and cigarette offers from peers.

METHODS

A cross-sectional survey was used for the study and included 248 male and female middle school students.

RESULTS

Results of structural equation modeling revealed that unsupervised time with peers is associated indirectly with adolescent smoking behavior through the mediation of association with delinquent peers, social expectancies about cigarette smoking, and cigarette offers from peers.

DISCUSSION

Interventions designed to motivate adolescents without adult supervision to associate more with friends who engage in prosocial activities may eventually reduce adolescent smoking. Further implications for structured supervised time for students outside of school time are discussed.

Salient environmental and perceptual correlates of current and established smoking for 2 representative cohorts of Indiana adolescents

PURPOSE

A secondary analysis of 2000 and 2004 Indiana Youth Tobacco Survey (IYTS) data was conducted to investigate salient environmental and perceptual correlates of adolescents' current and established smoking while controlling for demographic variables such as gender, grade, and race/ethnicity and to compare the pattern of significant correlates between the years.

METHODS

The IYTS was an anonymous school-based survey regarding tobacco use; familiarity with pro- and anti-tobacco media messages; exposure to environmental tobacco smoke (ETS); minors' access to tobacco products; and general knowledge, attitudes, and beliefs about tobacco. In 2000, a representative sample of 1416 public high school students in grades 9-12 and 1516 public middle school students in grades 6-8 (71.44% and 72.53% response rates, respectively) were surveyed. In 2004, 3433 public high school students and 1990 public middle school students (63.04% and 65.44 % response rates, respectively) were surveyed.

RESULTS

Significant predictors of adolescents' current and established smoking habits included exposure to ETS either in homes or in cars, exposure to pro-tobacco messages, perceived benefit of smoking, and perceived peer acceptance of smoking. The influence of exposure to pro-tobacco messages greatly outweighed exposure to any anti-tobacco messages.

CONCLUSIONS

The findings of this study warrant that more efforts and resources be placed on preventing youth from being exposed to ETS, and to control pro-tobacco marketing and improve the tobacco counter-marketing messages. The perceived benefits of smoking found here indicate that smoking for relaxation and weight control may be major influencing factors on adolescent smoking.

Therapy for specific problems: youth tobacco cessation

Cigarette smoking is the leading cause of premature morbidity and mortality in the United States. The majority of children smoke their first cigarette in early adolescence, and many older teens have well-established dependence on nicotine. Efforts to promote and support smoking cessation among these youth smokers are critical. The available experimental studies of youth cessation interventions find that behavioral interventions increase the chances of youth smokers achieving successful cessation. Currently there is insufficient evidence for the effectiveness of pharmacological treatments with youth smokers. Many innovative studies have been compromised by challenges in recruiting sufficient numbers of youth, obtaining approval for waivers of parental consent, and high attrition in longitudinal studies. Key areas for future work include bridging the fields of adolescent development and treatment design, matching treatments to developmental trajectories of smoking behavior, better understanding treatment processes and treatment moderators, and building demand for evidence-based cessation treatments.

Beyond quitting: predictors of teen smoking cessation, reduction and acceleration following a school-based intervention

There remains a great need for effective, cost-efficient, and acceptable youth smoking cessation interventions. Unfortunately, only a few interventions have been demonstrated to increase quit rates among youth smokers, and little is known about how elements of cessation interventions and participants' psychosocial characteristics and smoking histories interact to influence program outcomes. Additionally, few studies have examined how these variables lead to complete smoking abstinence, reduction or acceleration over the course of a structured cessation intervention. Data for the present investigation were drawn from a sample of teen smokers (n=5892) who voluntarily participated in either a controlled study or field study (i.e., no control group) of the American Lung Association's Not On Tobacco (N-O-T) program between 1998 and 2006 in five states. Results suggest that those who reduce smoking (but do not achieve full abstinence) are similar to those who quit on most measures except stage of change. Furthermore, it was found that those who increased smoking were heavier smokers at baseline, more addicted, were more likely to have parents, siblings, and significant others who smoked and reported less confidence in and less motivation for quitting than did those who quit or reduced smoking. Finally, a path model demonstrated how peers, siblings and romantic partners affected tobacco use and cessation outcomes differently for males and females. Implications for interventions are discussed.

Smoking cessation recruitment among African American youth: what youth think will help them attend

Data on the perceived sources of cessation information and the reasons why alternative school students would attend a smoking cessation program were collected from 302 students at an alternative high school who were surveyed through the Safer Decisions Program in Houston, Texas. Data collection took place between September 2006 and January 2007. Logistic regression identified that non-smokers were more likely to believe it was important to receive cessation information from doctors (4.93 adjusted odds ratio 95% confidence interval CI=1.96; 12.40), health educators (4.70 AOR; 95% CI=1.46; 15.10), people who have been affected by smoking (3.20 AOR; 95% CI=1.04; 9.80), teachers (2.73 AOR; 95% CI=1.3; 5.60), and celebrities (2.44 AOR; 95% CI=1.21; 4.92) compared to smokers. In addition, persons who had smoked in the past 30 days were twice as likely to report embarrassment (1.86 AOR; 95% CI=1.00; 3.44) and feel that it was not right to smoke (2.24 AOR; 95% CI=1.00; 5.00) compared to respondents who had not smoked during the past 30 days. While the relationships tested in this study are exploratory, they provide initial evidence for understanding the importance of smoking cessation recruitment strategies that may impact minority alternative school youth.

"I did it my way"--an explorative study of the smoking cessation process among Danish youth

OBJECTIVE

To explore the smoking cessation process of adolescents and their attitudes and beliefs towards smoking cessation and cessation interventions.

METHOD

Focus group discussions and individual interviews during April-May 2004 with 26 persons aged 15-21 years who all initiated a quit attempt on 1 January 2004.

RESULTS

The approach towards all stages of the youth smoking cessation process varied greatly among both successful and unsuccessful quitters. Apart from 'commitment' or the amount of energy put into a cessation attempt, there were no differences in the way successful and unsuccessful quitters approached the quit attempt. 'Smoking friends' and 'social support' were important for maintaining cessation. Further, participants had negative attitudes towards formalized smoking cessation interventions.

CONCLUSION

There are many approaches to the smoking cessation process. Whether an attempt is successful depends more on individual conditions and the amount of commitment invested in the attempt than on the specific cessation strategy used.

PRACTICE IMPLICATIONS

Future adolescent smoking cessation interventions should be flexible regarding both structure and content and should focus on the individual learning process, rather than adhering to rigid cessation strategies.

Reducing early smokers' risk for future smoking and other problem behavior: insights from a five-year longitudinal study

PURPOSE

To identify risk and protective factors during early and later adolescence that predict future regular smoking and multiple problem behavior among at-risk youth, defined as those who tried smoking by grade 7.

METHODS

At grades 7, 10, and 12, data were collected from 2,000 early smokers drawn from California and Oregon. Multivariate regression analyses tested predictors of the two grade 12 outcomes in separate models using data from grades 7 and 10. Gender interactions and buffering of risk factors by protective factors were assessed.

RESULTS

For at-risk youth, consistent protective factors against future smoking and problem behavior included living in an intact nuclear family (all four models) plus getting good grades and parental disapproval of smoking/drug use (three of four models). Consistent risk factors included exposure to substance-using peers (four models) and problems in school (three of four models). Adult substance use was a predictor during early, but not later, adolescence; pro-smoking/drug use beliefs were significant predictors during later adolescence. There were few differences across gender and no significant buffers against risk.

CONCLUSIONS

At-risk youth would likely benefit from peer resistance training, parental involvement in prevention efforts, and efforts to improve educational performance during both middle school and high school. Changing pro-drug beliefs may be more effective among older adolescents.

A randomized trial of nicotine nasal spray in adolescent smokers

OBJECTIVES

Nicotine nasal spray has been 1 of the most successful forms of nicotine-replacement therapy in adult populations. The nasal sprayer has not been studied in adolescent smokers. The objective of this pilot study was to determine the feasibility and utility of using nicotine nasal spray for adolescent smokers who wanted to quit smoking.

METHODS

Forty adolescent smokers who were between 15 and 18 years of age and smoked >/=5 cigarettes daily for at least 6 months were recruited from several San Francisco Bay area schools from 2005 to 2007. Using a randomized, open-label, 12-week trial, adolescent smokers were assigned to receive either weekly counseling alone (control) for 8 weeks or 8 weeks of counseling along with 6 weeks of nicotine nasal spray. Self-reported smoking abstinence was verified by both expired-air carbon monoxide and salivary cotinine.

RESULTS

There was no difference in cessation rates, the numbers of cigarettes smoked per day, or cotinine levels at 12 weeks. Fifty-seven percent of participants stopped using their spray after only 1 week. The most commonly reported adverse effect was nasal irritation and burning (34.8%) followed by complaints about the taste and smell (13%).

CONCLUSIONS

The unpleasant adverse effects, poor adherence, and consequent lack of efficacy observed in our pilot study do not support the use of nicotine nasal spray as an adjunct to counseling for adolescent smokers who wish to quit.

Is cigarette smoking related to alcohol use during the 8 years following treatment for adolescent alcohol and other drug abuse?

AIMS

The present study examined the relationship between cigarette smoking and alcohol use outcomes over an 8-year period following treatment for adolescent alcohol and other drug (AOD) use disorders.

METHODS

The present study was based on a sample of 166 adolescents recruited during inpatient AOD abuse treatment. Included in this study were 123 (74% of the full sample) participants, of whom 41% were female, 81% identified themselves as White and who averaged 15.9 years of age (SD = 1.3) when entering treatment. Data for the present study were drawn from interviews conducted at the time of treatment and 2-, 4-, 6- and 8-years post-treatment.

RESULTS

Twenty six percent of participants had quit smoking for > 1 year at the 8-year assessment, while 44% reported persistent smoking over time. Overall smoking rates decreased significantly over time. Subjects associated with the highest alcohol involvement trajectory reported significantly greater likelihood of persistent smoking as well as higher current smoking and cigarette consumption across time points.

CONCLUSIONS

The significant declines observed in smoking from adolescence into young adulthood were contrary to expectations, indicating that this behaviour may be less stable than previously thought among adolescent AOD abusers. Smoking involvement over time was greater within the highest alcohol use trajectory, consistent with previous evidence for a positive relationship between these behaviours. However, when compared with the general population smoking rates remained very high regardless of alcohol involvement. Thus, individuals treated for AOD abuse as adolescents remained at elevated risk for tobacco related disease regardless of post-treatment AOD use outcomes.

Evaluation of an Internet virtual world chat room for adolescent smoking cessation

The goal of this longitudinal study was to test an innovative approach to smoking cessation that might be particularly attractive to adolescent smokers. The study was a participatory research effort between academic and school partners. The intervention used an Internet-based, virtual reality world combined with motivational interviewing conducted in real-time by a smoking cessation counselor. Participants were 136 adolescent smokers recruited from high schools randomized to the intervention or a measurement-only control condition. Those who participated in the program were significantly more likely than controls to report at the immediate post-intervention assessment that they had abstained from smoking during the past week (p<or=.01), smoked fewer days in the past week (p<or=.001), smoked fewer cigarettes in the past week (p<or=.01), and considered themselves a former smoke (p<or=.05). Only the number of times quit was statistically significant at a one-year follow-up assessment (p<or=.05). The lack of longer-term results is discussed, as are methodological challenges in conducting a cluster-randomized smoking cessation study.

Addressing challenges in adolescent smoking cessation: design and baseline characteristics of the HS Group-Randomized trial

OBJECTIVE

Well-documented challenges have hampered both intervention development and research in teen smoking cessation. Addressing these challenges, the Hutchinson Study of High School Smoking (HS Study), the largest group-randomized trial in adolescent smoking cessation to date, incorporates several design innovations to investigate the effect of a counselor-initiated, individually tailored telephone counseling smoking cessation intervention for older adolescents. This paper presents and discusses these innovative design features, and baseline findings on the resulting study population.

METHOD

The trial used a population-based survey to proactively identify and recruit all high school juniors who had smoked in the past month - potentially expanding intervention reach to all smokers, even those who smoked less than daily and those not motivated to quit. For ethical and intervention reasons, some nonsmokers were enrolled in the intervention, also. Other important design features included the random allocation of schools into experimental conditions (intervention vs. no-intervention control) and a multi-wave design.

RESULTS AND CONCLUSION

The design innovations address problems and challenges identified in adolescent smoking cessation literature. The heterogeneous baseline characteristics of the study population, well-balanced between the two arms, have three significant implications: They (1) demonstrate the effectiveness of the trial's design features, (2) highlight several intervention-related issues, and (3) provide assurance that the trial's evaluation of intervention effectiveness will be unbiased.

Smoking cessation and stress among teenagers

The authors describe the experience of quitting smoking, focusing on the obstacles youth struggle with, based on individual interviews and focus groups with 54 teenagers in New York City. A major obstacle was the belief that people should stop smoking forever. The youth had to cope with temptation, frequent and often intense urges or cravings for cigarettes, and lack of social support from their family and friends. The young participants not only had to cope with general life stresses without being able to use cigarettes to reduce tensions but also had to contend with new stressful situations, such as friends who put them down for not smoking. In addition, the teens had to give up things that were important to them, such as friendships, during their quit attempts. The study describes how quitting can be a much more stressful experience for youth than research typically acknowledges. The authors discuss public health implications.

Getting it right: designing adolescent-centred smoking cessation services

AIMS

To demonstrate the importance of identifying adolescent preferences for smoking cessation in order to inform the design of effective adolescent cessation services.

DESIGN

Structured qualitative interviews drawing on means-end theory.

SETTING

Three youth-clubs and two secondary schools in south-east Wales.

PARTICIPANTS

Twenty-five male and female 13-18-year-olds, mainly daily smokers.

FINDINGS

Interviewees did not assume immediately that a smoking cessation service is something that will be available to them, and therefore they initially encountered difficulties in identifying attributes of such support. With further prompting interviewees were able to express a preference for support attributes, but these were not attributes that traditionally form part of cessation provision. Their main preference was for support from friends and family, access to nicotine replacement therapy and non-school-based, flexible support and guidance.

CONCLUSION

The results re-emphasize the inadequacies of existing cessation provision for meeting adolescent preferences and suggest that developing more adolescent-appropriate support requires a reconceptualization of existing interventions, with service users situated at the core of intervention design. The study highlights a number of service development points for intervention planners including: rethinking the timing and location of provision; placing more emphasis on the selection of facilitators; harnessing support from friends and family; and rooting these developments in broader tobacco control strategies.

[Benefit of brief interventions and pharmacotherapies for smoking cessation in teenagers]

Management of smoking includes approaches such as health advice against smoking, brief or intensive interventions, and pharmacotherapy. However, we do not have enough information on the use of such approaches in teenagers. School programs aimed at children and adolescents are perhaps the most widely used intervention and the one for which we have the most experience. Such programs should meet a series of well-defined criteria, but in recent years their effectiveness has been questioned. Currently, information is lacking on how effective these interventions are in young smokers who wish to stop. Several clinical guidelines recommend advice and a brief intervention in adolescents but are less specific regarding pharmacotherapy. By integrating advice and a brief intervention into existing smoking prevention and control programs in schools, such approaches could be used to combat smoking in children and adolescents. However, the information available on the use of such interventions in children and adolescents is insufficient and more research needs to be done, particularly by health care professionals specialized in the identification of susceptible individuals and treatment of smoking.

Readiness to change smoking behavior in adolescents with psychiatric disorders

There has been recent increased interest in utilizing motivational interviewing (MI) to increase adolescent readiness to quit smoking, but attempts to impact quit rates have thus far been discouraging. A better understanding of factors associated with adolescent readiness to quit smoking prior to receiving any intervention may provide guidance when tailoring future MI interventions in order to increase their effectiveness with this population. Adolescent smokers (N=191) who had been admitted to a psychiatric hospital and enrolled in a clinical trial evaluating MI completed questionnaires that assessed smoking behavior and variables thought to be related to smoking. Confidence to quit smoking and negative beliefs about smoking were significant predictors of adolescents' baseline readiness to quit smoking. The failure to demonstrate relationships between health consequences and readiness suggest that caution may be warranted in the use of feedback, a common component of MI-based interventions. Such feedback tends to focus on health consequences, which was unrelated to adolescent baseline readiness to change smoking behavior in the current study. Parallels between current results and the Theory of Planned Behavior are discussed in consideration of developing more effective MI-based interventions for adolescent smokers.

Five-year prospective prediction of self-initiated quitting of cigarette smoking of high-risk youth

This paper provides a 5-year replication-extension of a previous 1-year follow-up study of the same sample of southern California alternative high school youth. Demographic, behavioral, psychosocial, and emerging adult function predictors of adolescent self-initiated smoking cessation were investigated. Based on the first (1-year) prospective study and this follow-up, one may speculate that smoking cessation programs for adolescents should include counteraction of problem-prone attitudes, assistance with job aspirations and information about drug-free workplaces, motivation to quit strategies, and assistance with overcoming withdrawal symptoms.

Short-term effects of Project EX-4: a classroom-based smoking prevention and cessation intervention program

OBJECTIVE

Researchers continue to try to develop effective teen tobacco use prevention and cessation programs. Three previous school clinic-based studies established the efficacy of Project EX for teen smoking cessation. This fourth study adapts Project EX to the classroom context. This paper reports the findings based on pretest and posttest surveys conducted immediately prior and post-intervention.

METHODS

An eight-session classroom-based curriculum was developed and tested with a randomized controlled trial that involved a total of 1097 students in six program and six control continuation high schools. Program-specific knowledge and smoking measures were assessed at both the pretest and posttest surveys, and were used to evaluate the program's effect on the immediate outcomes. The immediate outcomes effects were analyzed with multi-level random coefficients models.

RESULTS

Program students provided favorable process ratings of the overall program and each session. Compared with the students in the control condition, students in the program condition showed a greater change in correct knowledge responses from pretest to posttest (beta=+5.5%, p=0.0003). Students in the program condition also experienced a greater reduction in weekly smoking (beta=-6.9%, p=0.038), and intention for smoking in the next 12 months (beta=-0.21 in 5-level scale, p=0.023).

CONCLUSIONS

EX-4 immediate outcome results revealed favorable student responses to the program, increases in knowledge, and decreases in smoking relative to a standard care control condition.

A national survey of tobacco cessation programs for youths

OBJECTIVES

We collected data on a national sample of existing community-based tobacco cessation programs for youths to understand their prevalence and overall characteristics.

METHODS

We employed a 2-stage sampling design with US counties as the first-stage probability sampling units. We then used snowball sampling in selected counties to identify administrators of tobacco cessation programs for youths. We collected data on cessation programs when programs were identified.

RESULTS

We profiled 591 programs in 408 counties. Programs were more numerous in urban counties; fewer programs were found in low-income counties. State-level measures of smoking prevalence and tobacco control expenditures were not associated with program availability. Most programs were multisession, school-based group programs serving 50 or fewer youths per year. Program content included cognitive-behavioral components found in adult programs along with content specific to adolescence. The median annual budget was 2000 dollars. Few programs (9%) reported only mandatory enrollment, 35% reported mixed mandatory and voluntary enrollment, and 56% reported only voluntary enrollment.

CONCLUSIONS

There is considerable homogeneity among community-based tobacco cessation programs for youths. Programs are least prevalent in the types of communities for which national data show increases in youths' smoking prevalence.

Initial evaluation of a real-world self-help smoking cessation programme for adolescents and young adults

There is a lack of effective smoking cessation programmes for young people, despite the urgent need for them. The present study reports the initial results of a real-world self-help cessation programme which also contained a "quit and win"-contest component designed for adolescents and young adults. Consecutive registrants (N=1265) were surveyed 11 to 23 months after they registered to the programme to assess continuous abstinence. Results must be interpreted cautiously because this is an uncontrolled study with a 20.7% response rate (N=262). The programme was assessed positively by the participants. Results showed an 8.5% intention-to-treat quit rate with an average duration of 51.30 weeks continuous abstinence. Predictors for successful smoking were occasional smoking (not daily smoking) and older age.

"Withdrawal symptoms" in adolescents: a comparison of former smokers and never-smokers

Since the early 1980s, investigators have been reporting that adolescent smokers felt "dependent" on cigarettes and that adolescents trying to quit smoking experienced the same withdrawal symptoms observed in adult quitters, including restlessness, insomnia, increased appetite and weight gain, irritability or anger, depression, craving for cigarettes, and trouble concentrating. We hypothesized that most of these symptoms might be attributed to adolescence itself. To investigate this hypothesis, we examined the prevalence of these seven "adult" withdrawal symptoms in a population of adolescent former smokers and never-smokers. Participants were high school students in Houston, Texas, participating in a nested, group-randomized control group study designed to estimate the impact of a CD-ROM intervention for smoking prevention and cessation. We measured differences in symptoms frequency between never-smokers and former smokers, matched in a 2:1 ratio on sex and race/ethnicity, and differences in symptoms among former smokers as a function of time since final quit attempt and prior level of smoking. Only former heavy smokers have shown significantly higher prevalence of withdrawal symptoms compared with never-smokers. Of the seven symptoms assessed, only craving incrementally increased with the intensity of smoking. Overall the individual withdrawal symptoms did not effectively differentiate between 112 never-smokers and 34 former lighter smokers (persons who used to smoke less than "a few cigarettes on most days"). Withdrawal symptoms can reliably differentiate former heavy smokers from light smokers and never-smokers, among adolescents. Because most adolescents tend to be lighter smokers, future tobacco use and cessation studies should interpret adult withdrawal symptoms among adolescents with caution.

Public and private domains of religiosity and adolescent smoking transitions

We used data from a nationally representative sample of US adolescents in school grades 7 through 12 to explore the effects of public and private religiosity on initiation, escalation, and cessation of smoking. We found that adolescents' decisions to experiment with smoking are influenced by both their individual practice of their faith and by participation in a larger faith community. However, the effects of private and public religiosity are specific to different decision points on the smoking uptake process. Private religiosity was protective against initiation of regular smoking among nonsmokers. It also was protective against initiation of experimental smoking but only when the young person frequently attended religious services or a religious youth group. Although private religiosity appeared to discourage the uptake of smoking, it was unrelated to reduction or cessation once a young person has become addicted to cigarettes. In contrast, public religiosity did predict reduction and cessation of cigarette use among regular smokers. Taken together, these findings demonstrate that the domains in which religiosity are important extend beyond the individual and include religious institutions.

Facilitating youth self-change through school-based intervention

Early interventions for youth with high rates of alcohol use have often suffered from lack of willing participation due to negative stereotypes about treatment and the impression that alcohol interventions are not developmentally relevant for adolescents. This study evaluated the effectiveness of a school-based voluntary secondary intervention for alcohol use (Project Options). 1254 high school students (55% girls; M age = 15.9, SD = 1.2) with a history of lifetime drinking completed survey measures after the first year of Project Options in 3 schools. These results suggest that the intervention was successful in recruiting high-frequency drinkers into the intervention as well as facilitating attempts to cut down or quit alcohol use in this group of adolescents. This study provides preliminary support for a consumer-based approach to alcohol intervention and design and use of voluntary secondary interventions in a school-based population.

Evaluation of an adolescent smoking-cessation media campaign: GottaQuit.com

OBJECTIVE

To evaluate the impact of a smoking-cessation media campaign for teens on utilization of a cessation Web site, GottaQuit.com.

METHODS

Telephone surveys were conducted before and after the implementation of a countywide media campaign to promote the use of a smoking-cessation Web site for youths. The surveys were designed to assess teen awareness and utilization of the Web site, as well as tobacco use and cessation attempts. Supplemental 2003 Youth Risk Behavior Survey items also assessed use of the Web site.

RESULTS

Most teen smokers reported that they wanted to quit smoking. Almost all teens reported exposure to GottaQuit.com ads and accurately identified GottaQuit.com as a Web site that offers cessation help for youths. Nearly 1 in 4 smokers who were trying to quit had visited GottaQuit.com or another Web site for cessation assistance.

CONCLUSIONS

The GottaQuit.com campaign effectively reached almost all teens, regardless of smoking status. Smokers were more likely than nonsmokers to have visited the Web site for help with quitting. Web adjuncts are likely to be used by adolescents who seek assistance in quitting.

An exploration of self-reported negative affect by adolescents as a reason for smoking: implications for tobacco prevention and intervention programs

BACKGROUND

Negative affect is related to initiation and maintenance of smoking among youth and understanding its role is important when developing effective prevention and cessation programs. This study investigates the relationship between adolescent negative affect and smoking dependence, behaviors, attitudes, and self-efficacy in order to shed light on differences in adolescent smoking maintenance and cessation.

METHODS

721 smoking youth participated in a cognitive-behavioral smoking cessation program. Reasons for smoking were categorized (alpha = 0.87) and youth were placed into one of two groups based on presence or absence of negative affect. One-way repeated measures ANOVA determined if differences existed between the groups on smoking behaviors, attitudes, and self-efficacy. One-way ANOVA determined if differences existed on Fagerström Nicotine Tolerance Dependence (FTND) scores.

RESULTS

Adolescents indicating negative affect for smoking were significantly more likely to have future smoking intentions and had significantly less self-efficacy to quit smoking than adolescent reporting other reasons.

CONCLUSIONS

This study supports the need to address negative affect among adolescents participating in prevention and cessation programs. An examination of negative affect will provide program developers and facilitators with information to improve their interventions, assist with cessation, and provide an avenue to access other needed health services.

Contemplating to quit current smoking status: differences in behavioural and psychosocial patterns in a population-based cohort of current smokers

BACKGROUND

Smokers actively considering to quit smoking were compared with hard-core smokers completely unwilling to change smoking habits with respect to psychosocial variables.

METHODS

A total of 3,229 current regular smokers aged 25-74 years were drawn from three population-based MONICA/KORA Augsburg surveys conducted between 1984 and 1995. Among them, 592 (8.4%) subjects were defined as active contemplators (AC) and 776 (22.6%) as immotives (IM). Multivariate logistic regression analysis stratified by sex was used to identify active contemplators.

RESULTS

No differences between ACs and IMs were observed for sex and age. Active contemplating in females was strongly mediated by impaired self-rated health [Odds ratio (OR) 2.29; 95% CI 1.42-3.69] and somatic complaints (OR 2.10; 95% CI 1.29-3.48). For men, depression (OR 2.49; 95% CI 1.64-3.79) and not living alone (OR 2.20, 95% CI 1.51-3.20) promoted being AC. Long-term survival was impaired for IM compared to AC. The odds ratio for smoking cessation of ACs compared to IMs was 1.77 (95% CI 1.25-2.50).

CONCLUSIONS

Sex-specific differences in factors associated with the intention to quit smoking were observed and may lead to sex-specific targets in prevention strategy. IMs may be victims of a conceited healthy smoker effect triggered by the absence of disabling body or affective symptoms.
