INTRODUCTION Despite efforts to prevent smoking, the prevalence of smoking in Spanish adolescents remains high. So far, there are no evidence-based smoking cessation programs for adolescents in Spain. METHODS This study describes the evaluation of Project EX, an eight-session school-based clinic smoking cessation program, with Spanish cigarette smokers 13-19 years of age, from 9 schools (four program condition schools and five control condition schools). A group-randomized controlled trial was used. There were 211 smokers at baseline (112 program group, and 99 control group). Evaluation involved an immediate pretest and posttest survey (administered five-weeks later) and six-month follow-up (after the immediate posttest). RESULTS At immediate posttest, Project EX significantly reduced future nicotine dependence scores (mFTQ; p<.001), and increased intention to quit smoking (p<.001), and led to a higher previous day (prior to assessment) quit rate (p<.03). At the six-month follow-up, the percentage of quitters in the program group was 14.28%, whereas no smokers quit smoking in the control group (p<.04), and Project EX had a significant influence on future smoking expectation (p=.006) and overall level of 30-day smoking. CONCLUSIONS Results for the Project EX school-based clinic are promising for adolescent smokers in Spain, although difficulties in recruitment and high attrition are of concern. Findings and limitations are discussed and suggestions for future research are suggested.

BACKGROUND There has been an increase in adolescent substance use that has led to the development and implementation of prevention programs. New evidence is needed in order to improve them and optimize the resources. The aim of this paper is to use a meta-analysis to analyze the effectiveness of school drug prevention programs in Spain. METHOD Twenty-one studies that evaluated drug abuse prevention programs in schools, were published between 2002 and 2013, and that met the selection criteria were identified. RESULTS Preventive program effectiveness was low ( d = 0.16), although it was higher at the follow-up ( d = 0.30). The programs were most effective in changing attitudes ( d = 0.44) towards drugs. The models of health education ( d = 0.48) and social learning ( d = 0.20) were also very effective, especially in combination with oral, written, and audiovisual support material ( d = 0.21) and the implementation of joint programs by health education professionals and faculty members ( d = 0.25). CONCLUSIONS Is possible to determine the need for more rigorous evaluations of interventions to establish useful programs.

Tobacco use is of high prevalence among Spanish adolescents. Programming to counteract tobacco use has been needed. There is a lack of knowledge on the efficacy of teen tobacco use cessation programming. The current study provides an immediate outcome evaluation of the Project EX tobacco use prevention and cessation program among Spanish adolescents. An eight-session, classroom-based curriculum was translated from English to Spanish and adapted to the Spanish culture. Next, it was tested using a randomized controlled trial with 1,546 Spanish students, involving three program and three control high schools. Participants at the program group provided moderately favorable process ratings of the program. Compared to the standard care control condition, the program condition revealed a greater reduction in smoking intentions and CO ppm levels.

Background Tobacco use prevalence rates are high among Spanish adolescents. Programming to counteract tobacco use is needed. Methods and Findings The current study provides a one-year follow-up outcome evaluation of Project EX, an eight-session classroom-based curriculum. The intervention was tested using a randomized controlled trial with 1,546 Spanish students, involving three program and three control schools. Compared to the control condition, the program condition revealed a greater reduction in nicotine dependence (p < .05) and CO ppm levels (p < .001), and lower consumption of cigarettes at last month (p = .03). Conclusions Long-term outcomes of the Project EX classroom-based program are promising for adolescent prevention and possibly cessation in Spain.

Adolescent smoking is a major public health problem, which has led to the development of cessation programs such as Project EX. However, there is no evidence for the long-term efficacy of cessation among Spanish adolescents. This study provides a 1-year follow-up evaluation of the Project EX tobacco use cessation program among 211 smokers. The intent-to-treat 30-day smoking quit rate for the program group was 7.81 percent (p = .04), whereas no smokers quit in the control group (p = .02). The intervention had a significant influence on future smoking expectation, intention, motivation to quit, and overall level of 30-day smoking. Long-term outcomes of the Project EX clinic-based program are promising for adolescent smokers in Spain.

Predicting Alcohol-Impaired Driving among Spanish Youth with the Theory of Reasoned Action

José P. Espada; Kenneth W. Griffin; María T. Gonzálvez; Mireia Orgilés

Alcohol consumption is a risk factor for motor vehicle accidents in young drivers. Crashes associated with alcohol consumption typically have greater severity. This study examines the prevalence of driving under the influence among Spanish youth and tests the theory of reasoned action as a model for predicting driving under the influence. Participants included 478 Spanish university students aged 17-26 years. Findings indicated that alcohol was the substance most associated with impaired driving, and was involved in more traffic crashes. Men engage in higher levels of alcohol and other drug use, and perceived less risk in drunk driving (p < .01). The study confirms that alcohol use and driving under the influence of alcohol are highly prevalent in Spanish young people, and some gender differences exist in these behaviors (p < .01). Furthermore, the study confirms the validity of theory of reasoned action as a predictive model of driving under the influence of alcohol among youth in Spain (p < .001) and can help in the design of prevention programs.

In Spain, 44% of 14–18-year-olds have smoked, and 12.5% have smoked cigarettes in the last 30 days. Nicotine is one of the most addictive substances, and can lead to serious addiction in adulthood with adverse consequences to one’s health. School plays a relevant role in health promotion and preventing risk behaviors such as tobacco consumption. Despite the fact that some school-based tobacco cessation and prevention interventions prove to be effective for their purposes, there is a lack of understanding as to why these programs succeed or fail. This longitudinal study aims to test the nicotine dependence (ND) as a mediator of Project EX’s effect – a tobacco-use cessation program developed for high school youth to reduce tobacco consumption in scholars. Six high schools located in the Mediterranean coast were randomized for the participation of the program (Spanish version of Project EX) or a waiting-list group with baseline, immediate-posttest, and 12-month follow-up assessments. At baseline, 1,546 adolescents aged 14–21 years old (mean age: 15.28; SD = 1.20; 46% were women) were evaluated by self-administered tests on tobacco consumption and ND. A biomarker of smoke inhalation – a measurement of exhaled carbon monoxide (ECM) – was used. Participants who were smokers (N = 501; 32%) were selected for this study. Mediation analyses were conducted using the PROCESS v2.12 macro for Windows. The significant criterion was p ≤ 0.05, and 5,000 samples were used for bias-corrected bootstrap confidence intervals. Results indicated that Project EX indirectly decreased the number of cigarettes smoked in the last month, the number of cigarettes smoked within the last 7 days, the number of daily cigarettes, and ECM level at 12-month follow up through decreasing the level of ND in the short-term. This is the first Spanish study that explores ND as a mediator of the long-term efficacy of Project EX to reduce tobacco consumption in adolescents. Results suggest that interventions that reduce ND at short-term are more likely to be successful to decrease tobacco use at long-term.

El uso problemático de videojuegos está relacionado con problemas emocionales en adolescentes

María T. Gonzálvez; José P. Espada

Problem use of video games is an increasing risk behaviour. High exposure of adolescents to video games has been linked to a variety of disorders, but the relationship between problem video game playing and emotional welfare is unknown. The aim of the study is to analyse problem video game playing in a sample of adolescents and to determine whether there are differences between online and offline players, in addition to examining its relationship with anxiety and depressive symptomatology. A sample of adolescents (N = 380) completed self-reports measuring video game use and symptoms of anxiety and depression. We found that 7.4% of females and 30% of males can be considered as playing at problem levels. Online players were almost 12 times more likely to play at high frequency than offline players (χ2 (1, 267) = 72.72, p < .001, OR = 11.63, 95% CI [6.31, 21.43]). Males play more frequently, and play more online (χ2 (1, 267) = 50.85, p < .001, OR = 6.74, 95% CI [3.90, 11.64]), with a clear relationship between problem video game playing and anxiety (r = .24; p < .001). In females, there is a relationship between problem video game playing and depression (r = .19; p < .05). Our findings contribute to a better understanding of the psychological variables involved in problem video game playing. The implementation of strategies is suggested in order to prevent pathological gaming and associated problems.

Background: Project EX is a classroom-based smoking prevention and cessation intervention program that has been well evaluated and designed for assessing the prevention and cessation effects among adolescents in Spain. However, its long-term efficacy is still unknown. This study deals with the outcomes of a 2-year follow-up evaluation of Project EX. Methods: The intervention was tested using a clustered randomized controlled trial involving 1,546 Spanish students from 3 program schools and 3 control schools. At the end of the 2-year follow-up period, 722 subjects had completed the questionnaires (266 in the control condition and 456 in the program condition) administered to them. Results: Compared to the control condition, the program condition revealed a greater reduction in nicotine dependence (p = 0.04), smoking intention (p = 0.02), and in the number of cigarettes smoked during the previous month (p = 0.03). The CO monitor repeated assessments revealed a significant decrease of ppm levels in the program group (p < 0.001). Intent-to-treat quit rates were 14.28 and 0%, respectively, for the program and control conditions. Conclusions: This study provides evidence about the long-term effectiveness of the Project EX classroom-based program for smoking prevention and cessation among adolescents in Spain.

María T. Gonzálvez; Alexandra Morales; Mireia Orgilés; José P. Espada

Purpose of ReviewSpain has one of the highest smoking rates among adolescents and young adults worldwide. Smoking prevention and cessation programs have been developed for this population; however, the status of evidence-based programs in Spain remains unknown. Previous reviews evaluated the efficacy of smoking prevention and cessation programs, but an update of the results is needed for these and new interventions implemented in Spain. The objective of this paper was to examine the current status of evidence-based smoking prevention and cessation programs for Spanish adolescents and young adults.Recent FindingsThe current prevalence of tobacco use among Spanish adolescents is described at the state level. We reviewed the results of drug-prevention programs (including tobacco) and provide an in-depth analysis of evidence-based school programs, focused on prevention and cessation of tobacco use in SpainSummaryThe strengths and shortcomings of the programs are identified, and recommendations for future studies and applications are proposed.
