Uso problemático de Internet y móvil en adolescentes y jóvenes españoles

The objective of this study was to examine the variables that affect the use of PowerPoint by university professors. Based on the revised unified theory of acceptance and use of technology (UTAUT-2), a theoretical model adapted to the study context was proposed. The impact of the attitude towards PowerPoint, performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic motivations, and habit, in the intention to use and actual use of PowerPoint was evaluated. A survey was applied to 106 university professors from two Spanish universities, and the theoretical model was subsequently tested using a path analysis. The results suggest the existence of a direct non-critical path consisting of social pressure and habit, and an indirect critical path consisting of performance expectancy via the attitude towards PowerPoint. This research highlights the importance of critical reflection in the use of technological tools such as PowerPoint in classrooms. The practical implications of these findings to improve pedagogical practices are discussed.

The level of life satisfaction perceived during childhood and adolescence is an excellent indicator of healthy psychological emotional development. The main aim of this work is to study the levels of life satisfaction perceived by young people throughout their childhood and adolescence. To this end, an innovative retrospective approach is adopted that shows how the evolution of life satisfaction is perceived at different ages according to gender. The present study is based on a sample of 600 Spanish adolescents (58.1% girls; mean age = 16.64) who report the evolution of their life satisfaction from 6 years to 18, through the Life Satisfaction Chart (LSCh). The Goldberg Anxiety and Depression Scale (GADS) is also administered to record levels of anxiety and depression. The results indicate no gender differences in terms of life satisfaction during childhood. Levels of life satisfaction are significantly higher in childhood than in pre-adolescence and adolescence and a significant decrease in levels appearing towards the age of 11. As for gender, significant differences in life satisfaction appear from the age of 12, with girls being significantly more dissatisfied, more depressed and more anxious than boys. Current levels of anxiety and depression do not appear to interfere with retrospectively reported levels of life satisfaction throughout the developmental years studied, except among the female population, where minimal interference is detected. Life satisfaction retrospectively reported by young people shows a significant decrease after the age of 11 years, with greater emotional and psychological vulnerability after this age, mainly and notably among girls. The present results highlight the importance of psychological/affective care in the pre-adolescent and adolescent stages, especially among the female population.

Casual videogames (CVGs), played on smartphones, are becoming increasingly popular, especially among females and adults. Whereas the addictive potential of online (computer) videogames is well-established, there is yet insufficient evidence for Internet gaming disorder (IGD) in mobile gamers and for the mediating role of some mechanisms involved. The aim of this study is to investigate the impact of the frustration of psychological needs on mobile videogamers’ addictive behavior as well as the role of cognitions (game-use expectancies) and behaviors (time spent playing) through a hypothesized serial mediation model, while controlling for important correlates, such as game genre, age, gender and payment during play. A total of 471 mobile game users (211 males) with an average age of 21.73 replied to an online survey containing sociodemographic and game variables, the Need Satisfaction and Frustration Scale (NSFS), the Internet Gaming Disorder Scale-Short Form (IGDS9-SF) and a slightly modified version of the Internet Use Expectancies Scale (IUES). The results corroborate the negative effects of need frustration on IGD among mobile gamers and clarify the role of time spent playing and game-use expectancies in the development of IGD, highlighting the important role of cognitions in this relationship. We conclude that both the time spent playing and game-use expectancies should be important targets for clinical interventions, even though they are not included in the diagnostic criteria.

Research on personality and circadian typology indicates evening-type women are more impulsive and novelty seeking, neither types are more anxious, and morning types tend to be more active, conscientious, and persistent. The purpose of this study is to examine the differences between circadian typologies in the light of the Zuckerman's Alternative Five-Factor Model (AFFM) of personality, which has a strong biological basis, in an adult sample of 412 women 18 to 55 yrs of age. The authors found morning-type women had significant higher scores than evening-type and neither-type women on Activity, and its subscales General Activity and Work Activity. In contrast, evening-type women scored significantly higher than morning-type women on Aggression-Hostility, Impulsive Sensation Seeking, and its subscale Sensation Seeking. In all groups, results were independent of age. These findings are in accordance with those previously obtained in female student samples and add new data on the AFFM. The need of using personality models that are biologically based in the study of circadian rhythms is discussed. (Author correspondence: anna. muro@uab. cat )

Objetivo Analizar los efectos de la estabilidad contractual de los profesores universitarios en las dimensiones psicosociales de satisfacción, salud y estrés.Método Estudio descriptivo cuasi-experimental, tomando como muestra a 145 profesores de siete universidades públicas catalanas. El estudio se realizó durante el mes de abril de 2014. Se utilizó como base el cuestionario ISTAS21, versión media, en lengua castellana, del Cuestionario Psicosocial de Copenhaguen. De las 21 escalas incluidas, sólo se han tenido en cuenta las siete escalas relacionadas con los factores evaluados. Se realizaron una serie de análisis de varianza (ANOVA) considerando las puntuaciones obtenidas en las tres dimensiones psicosociales evaluadas como variables dependientes y la estabilidad laboral (permanencia y dedicación laboral) como variable independiente.Resultados Los profesores de tiempo completo con contratos laborales temporales muestran una peor salud física y mental —a pesar de ser el grupo más joven—, mayores síntomas de estrés y una menor satisfacción laboral, en comparación con profesores a tiempo completo y contrato estable; o profesores de tiempo parcial.Conclusiones La estabilidad laboral tiene repercusiones en la salud y calidad de vida laboral de los profesores que se encuentran en situación de inestabilidad, teniendo ello además repercusiones en la docencia y la investigación.
