The problematic use of technology of children and adolescents is becoming a growing problem. Research has shown that excessive technology use predicts a variety of psychological and physical health problems. The aim of this study was to analyze the role of leisure time activities (structured and unstructured) in adolescents as a predictor of problematic technology use. Participants were 7723 adolescents, of which 55% were girls, from four Spanish-speaking countries (Chile, Spain, Mexico, and Peru) between the ages of 13 and 18 years. The evaluation instrument applied was the YOURLIFE project self-report questionnaire. Two executive functions were measured: goal setting and inhibitory control. Using structural equation modeling, findings indicated that structured leisure time activities predicted less PTU, whereas unstructured activities predicted more PTU, MLχ² (69, N = 7723) = 806.60; CFI = 0.929, RMSEA = 0.042, and the model had good predictive capacity for PTU (R² = 0.46). Structured and unstructured activities also showed indirect effects on PTU through executive functions. As adolescents spent more time in unstructured leisure activities, poorer goal setting, inhibitory control skills, and more PTU were found. The opposite was true for structured leisure time activities. Implications of structured leisure activities to develop executive functioning and to prevent PTU for adolescents are discussed.

Participation in organized Extracurricular Activities has contributed to improve academic achievement. However, this does not happen in the same way; it depends on sex, age, or parental educational level. Our objective is to know the importance of these factor interactions’ in the explanation of academic achievement. The sample consisted of 1148 adolescents, aged between 12 and 18 years, 52% of whom were female. Participants completed the Extracurricular Activities questionnaire, and academic and sociodemographic data were collected. The results show that differences in academic achievement depend on the adolescent stage. In early adolescence, girls improve in academic achievement, as well as with better parental education, reading of books and activity duration. On the contrary, in the middle and late adolescence, academic achievement improves with not participating in collective sports and reduced activity breadth, although parental educational level follows the same trend as in the early adolescence. These results reinforce the evolutionary hypothesis of specialization in the choice of activities throughout adolescence. In this sense, some proposals for schools that advocate for greater integration of curricular and non-curricular elements are discussed.

The main objective of this study was to analyze the relationship between structured, unstructured, and family leisure activities on the frequency of adolescent alcohol intake across three different countries (Spain, Peru, and The Netherlands). The self-control of adolescents was also investigated as a moderator in the relationship between leisure activities and alcohol consumption. Methodology: This research involved 4608 adolescents aged between 12 and 17 from three countries (Spain, Peru, and The Netherlands). In Spain and Peru, data was collected through a self-report questionnaire which was part of the Your Life project. In The Netherlands, a self-questionnaire was used, collected by the University of Utrecht. A multiple logistic regression was performed for each country. Results: The results showed that participation in unstructured leisure activities increased the likelihood of drinking more frequently and more heavily in all three countries. Structured leisure activities, in general, did not have a significant predictive effect on alcohol consumption in any of the countries. Family leisure activities reduced the risk of engaging in yearly alcohol use and yearly binge drinking among adolescents, especially in The Netherlands and Spain. The protective effect of family leisure and unstructured leisure risk on yearly alcohol use applied especially to Dutch adolescents with a low level of self-control. Discussion: The article emphasizes the need for parents to engage in leisure activities with their child; participation in unstructured activities is not to be encouraged.

A partir del siglo XX el ocio ha tenido un papel crucial en la sociedad, la economía, la cultura y la educación. Este hecho ha despertado un gran interés por estudiar la conexión que tiene este fenómeno con los estilos de vida, la satisfacción, el entorno, y la relación entre ocio y trabajo. Este artículo analiza la influencia del ocio en la vida de los jóvenes. En la primera parte, se realiza una revisión bibliográfica de las principales teorías sociológicas y psicológicas que explican su sentido, evolución y relación con el trabajo. En la segunda parte, se expone el modelo de desarrollo positivo, centrado más en el florecimiento del potencial de los jóvenes que en prevenir conductas de riesgo. El uso positivo del tiempo libre se basa en la realización de actividades estructuradas, con participación voluntaria, motivación intrínseca y supervisadas por adultos. Se concluye que la implicación de los jóvenes en asociaciones, organizaciones e instituciones que desarrollen actividades estructuradas de participación voluntaria o autoimplicada facilita la transición a la vida adulta, en relación con el uso constructivo del tiempo unido a un ocio libre y placentero.
