The aim of this study is to adapt and validate the Game Addiction Scale for Adolescents (GASA) to the Spanish youth population. Cultural adaptation and validation study. Secondary Education centres. Two independent studies were conducted on a group of 466 young people with a mean age of 15.27 years (13-18, SD: 1.83) and 48.7% ♀ and on another group of 566, with a mean age of 21.24 years (19-26; SD: 1.86) 44.1% ♀. Addiction to video games (GASA); Game behavior (Game habits usage questionnaire), Impulsiveness (Plutchik Impulsiveness Scale) and Group Pressure (Ad hoc questionnaire). The Spanish version of GASA has shown good reliability and true to the original scale factor structure. As regards criterion validity, GASA scores are significantly different according to four criteria related to problem gambling: Game intensity and frequency, impulsiveness, and peer pressure. The results show that the adapted version GASA is adequate and a valid tool for assessing problematic gaming behaviour.

Gambling disorder in youth is an emerging public health problem, with adolescents and young adults constituting a vulnerable age group for the development of gambling-related problems. Although research has been conducted on the risk factors for gambling disorder, very few rigorous studies can be found on the efficacy of preventive interventions in young people. The aim of this study was to provide best practice recommendations for the prevention of disordered gambling in adolescents and young adults. We reviewed and synthesized the results of existing RCTs and quasi-experimental studies covering nonpharmacological prevention programs for gambling disorder in young adults and adolescents. We applied the PRISMA 2020 statement and guidelines to identify 1483 studies, of which 32 were included in the systematic review. All studies targeted the educational setting, i.e., high school and university students. Most studies followed a universal prevention strategy, that particularly targeted adolescents, and an indicated prevention strategy for university students. The reviewed gambling prevention programs generally showed good results in terms of reducing the frequency and severity of gambling, and also regarding cognitive variables, such as misconceptions, fallacies, knowledge, and attitudes towards gambling. Finally, we highlight the need to develop more comprehensive prevention programs that incorporate rigorous methodological and assessment procedures before they are widely implemented and disseminated.

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. 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. 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). Is possible to determine the need for more rigorous evaluations of interventions to establish useful programs.

Although gambling is forbidden for minors, the prevalence of gambling among adolescents is increasing. In order to improve preventive interventions, more evidence on predictors of gambling onset is needed. A longitudinal study was proposed to (1) establish the prevalence of gambling; (2) identify factors associated with gambling behavior the following year; and (3) adjust a model to predict gambling behavior. A cohort of 1074 students (13–18 years old) was followed for 12 months. The prevalence of gambling reached 42.0% in the second measure. Boys gambled 2.7 times more than girls, and the highest percentages of gambling onset showed up between 13 and 14 years old. Gambling onset and maintenance was associated with gender, age, sensation-seeking, risk perception, self-efficacy for not gambling, parents’ attitude towards gambling, group pressure (friends), subjective norm, exposure to advertising, accessibility, normative perception, gambling in T₁ and parents gambling behavior. Gender, gambling in T₁ and risk perception were significant in all three logistic adjusted regression models, with the fourth variable being sensation seeking, peer pressure (friends) and accessibility, respectively. It is suggested that universal prevention should be aimed preferably at children under 15 years old and to alert regulators and public administrations to the directly proportional relationship between accessibility and gambling onset.

En España, uno de cada cuatro jóvenes de 14 a 18 años declara haber consumido cannabis en el último año. La demanda de tratamiento ha aumentado en todos los países europeos. Ello ha motivado el desarrollo de intervenciones preventivas que requieren instrumentos para el cribado de la población en riesgo y la evaluación de la prevención. La Teoría de la Acción Planificada (TAP), ampliamente utilizada para predecir las intenciones conductuales, ha mostrado una buena capacidad predictiva en el campo de las adicciones. El objetivo del presente trabajo es diseñar y validar un Cuestionario de Intención de Consumo de Cannabis (CUIQ, Cannabis Use Intention Questionnaire) basado en la TAP. 1011 adolescentes completaron una batería de cuestionarios que se compone de cuatro subescalas: actitud hacia el consumo, norma subjetiva, autoeficacia hacia la abstinencia e intención de consumo. El Cuestionario CUIQ obtuvo buenas características psicométricas. Las ecuaciones estructurales confirmaron el modelo predictivo sobre la intención de consumo en adolescentes españoles (consumidores y no consumidores), llegando a explicar el 40% de la varianza. El CUIQ tiene como objetivo una mejor comprensión del proceso psicológico que conduce al consumo de cannabis y permitir la evaluación de programas. Esto puede ser especialmente útil para mejorar el diseño e implementación de programas de prevención selectiva.

Problems related to the use of the internet have triggered the appearance of internet addiction. With this problem comes the need for prevention. The objective of this study is to update the knowledge about the effectiveness of internet addiction prevention programs in schools. The specific aims are: (1) to identify the objectives of school’s prevention programs, (2) to analyse the components and instruments used, (3) to evaluate the quality of the relevant studies and (4) to compare the results of the publications. A search with the terms "Internet", "Internet Use Disorder", "addiction", "prevention", "school", "effectiveness", and "prevention program" was carried out in 10 bibliographic databases in August 2021. For the selection of articles, the 25 quality criteria of the CONSORT 2010 list were used. Only articles that evaluated school prevention programs and had a quality score greater than 10 were selected. The results are shown in three tables. Eleven publications that met the inclusion criteria were identified. The measurement scales used are very heterogeneous. Ten of the 11 programs were effective in preventing adolescent internet misuse, abuse, or addiction. Increasing students' self-control reduces the problem of internet abuse. The validity of the results is discussed considering the methodological quality of the studies.
