Identifying mechanisms that explain the relationship between anxiety and depression are needed. The Tripartite Model is one model that has been proposed to help explain the association between these two problems, positing a shared component called negative affect. The objective of the present study was to examine the role of loneliness in relation to anxiety and depression. A total of 10,891 school‐based youth (Grades 2–12) and 254 clinical children and adolescents receiving residential treatment (Grades 2–12) completed measures of loneliness, anxiety, depression, and negative affect. The relationships among loneliness, anxiety, depression, and negative affect were examined, including whether loneliness was a significant intervening variable. Various mediational tests converged showing that loneliness was a significant mediator in the relationship between anxiety and depression. This effect was found across children (Grades 2–6) and adolescent (Grades 7–12) school‐based youth. In the clinical sample, loneliness was found to be a significant mediator between anxiety and depression, even after introducing negative affect based on the Tripartite Model. Results supported loneliness as a significant risk factor in youths' lives that may result from anxiety and place youth at risk for subsequent depression. Implications related to intervention and prevention in school settings are also discussed. 相似文献

Physical activity attenuates the symptoms of fibromyalgia, and its level is oftentimes associated with the perceived environment of fibromyalgia patients. Within this context, we aimed to study the reliability of the Spanish version of the Assessing Levels of Physical Activity (ALPHA) environmental questionnaire and the mode of commuting questionnaire. We also studied the association between the perceived environment and mode of commuting with physical activity levels among female fibromyalgia patients in Spain. Test–retest reliability was judged by the intra-class correlation coefficient (ICC), weighted kappa statistic, Spearman correlations and the proportion of agreement. We calculated bivariate Pearson’s correlations between environmental sum scores and physical activity measured by both International Physical Activity Questionnaire (IPAQ) and accelerometry. More than 70% of the scales and items showed a good reliability regarding the ICC, the weighted kappa, the Spearman correlation and the percentage of inter-agreement (higher than 50%). The perceived environment assessed with the ALPHA showed a low correlation with both IPAQ and accelerometry. The Spanish version of the ALPHA environmental questionnaire proved to be reliable and showed a weak degree of association with physical activity in female fibromyalgia patients. 相似文献

ResumenEn el presente trabajo se reinterpreta el problema de la motivación para el rendimiento académico desde una perspectiva cognitiva, fundamentada en la teoría de la autoeftcacia. Se hace hincapié en el papel de las expectativas de eficacia como mediadoras entre las habilidades y el rendimiento de los sujetos y se acentúa el papel que juega la motivación cognitivamente basada en el proceso de aprendizaje. Postulamos, asimismo, la necesidad de fomentar la autoevaluación frente a la evaluación externa y los sistemas que permitan el desarrollo de la motivación intrínseca para el aprendizaje. 相似文献

ResumenSe hace una revisión de las investigaciones soviéticas y occidentales sobre el desarrollo de las acciones de memoria (estrategias en la terminología occidental). La distinción entre actividades y procesos de memorización no deliberada y actividades y procesos de memorización deliberada facilita la integración de las aportaciones de ambas vías de investigación, soviética y occidental. En todo el desarrollo de las acciones de memoria, el aspecto central es la adquisición de control por parte del sujeto (control que va transfiriéndose del adulto al niño de forma gradual) que culmina con la constitución del sistema ejecutivo de control de la memoria. Se afirma, finalmente, que el concepto de Zona de Desarrollo Próximo de Vigotsky permite caracterizar este desarrollo de modo más realista y complejo que la noción de deficiencia de producción. 相似文献

This paper investigates the determinants of the transition from higher education to work across Europe using various specifications
of duration models and a one-time multi-country survey of university graduates from nine European countries. Results point
to differences between the North and South of Europe in the difficulty of getting a first job. They confirm that individual
characteristics such as the field/level of studies or the socioeconomic background, and individual job search bear a significant
relationship to the probability of finding a job. Evidence of unobserved heterogeneity is also found. 相似文献
