El teléfono móvil: disponibilidad, usos y relaciones por parte de los adolescentes entre 12 y 16 años

Presentamos los resultados de una investigación sobre el uso, la disponibilidad y algunos aspectos relativos a las relaciones que se establecen con diferentes personas en torno al teléfono móvil en una muestra de adolescentes (N=1211) entre 12 y 16 años de la provincia de Girona. Los resultados ponen de manifiesto la existencia de diferencias de género en cuanto a su disposición y uso, siendo las chicas las que en mayor porcentaje poseen un móvil y más horas dedican a usarlo. Los adolescentes prefieren hablar sobre lo que hacen con el móvil con los iguales, seguido de los hermanos o las hermanas y, en último lugar, con los adultos (progenitores y profesores o profesoras). Finalmente, se analiza cómo los adolescentes se muestran más interesados por e informados sobre Internet y el móvil en comparación con los otros cuatro medios audiovisuales explorados (televisión, ordenador, juegos para ordenador y videojuegos)

Measurement invariance of Personal Well-Being Index (PWI-8) across 26 countries

This report examines the measurement invariance of the Personal Well-being Index with 8 items (PWI-8). University students (N = 5731) from 26 countries completed the measure either through paper and pencil or electronic mode. We examined uni-dimensional structure of PWI and performed a Multi-group CFA to assess the measurement invariance across the 26 countries, using conventional approach and the alignment procedure. The findings provide evidence of configural and partial metric invariance, as well as partial scalar invariance across samples. The findings suggest that PWI-8 can be used to examine correlates of life satisfaction across all included countries, however it is impossible to compare raw scores across countries

Belief in a Zero-Sum Game and Subjective Well-Being Across 35 Countries

This article presents a short research report on the relationship between perceived antagonism in social relations measured using the Belief in a Zero-Sum Game (BZSG) scale, life satisfaction, and positive and negative affect. Given that individuals who believe that life is like a zero-sum game are likely to perceive their daily interactions with others as unfair, we expected that individuals with high BZSG experience more negative affect and fewer positive one, resulting in a lower satisfaction with life. In addition, we examined whether country-level BZSG may play a moderating role in these associations. Data were collected from student samples (N = 7,146) in 35 countries. Multilevel modelling revealed that perceived social antagonism in social relations is negatively associated with satisfaction with life and that this relationship is mediated by both positive and negative affect at the individual level. The relation of individual BZSG and negative affect on satisfaction with life were weaker in societies with higher country-level BZSG, suggesting that the effects of BZSG may be less detrimental in these countries. These findings extend previous knowledge about predictors of life satisfaction and suggest that social beliefs might also be an important factor that influences subjective well-being. The contribution of the study is that the separate treatment of life satisfaction and positive and negative affect may be helpful in many research situations, particularly from a cross-cultural perspective
