El apoyo social percibido es considerado un factor clave para la reducción del riesgo de estrés psicológico, fracaso académico y abandono de los estudios universitarios; sin embargo, la investigación relativa al modo en que el apoyo social puede incidir en el rendimiento académico de los estudiantes universitarios es escasa. El presente estudio examina la relación de diferentes provisiones y fuentes de apoyo social con el rendimiento académico de estudiantes universitarios españoles, en su primer y tercer curso. La muestra estaba compuesta por 219 adultos emergentes, 149 mujeres y 70 hombres, con una edad media de 18.01 años (SD= 0.46), matriculados en distintas titulaciones de una universidad pública española. Los datos se recabaron durante el primer año académico (tiempo 1) y de nuevo en el tercer año (tiempo 2). Los análisis de regresión realizados  mostraron que diferentes dimensiones del apoyo social percibido predecían el éxito académico en el intervalo de dos años. Los resultados del estudio podrían servir para mejorar programas y políticas dirigidas a promover el ajuste y rendimiento académico de los estudiantes. Perceived social support is considered a key factor for reducing the risk of psychological distress, academic failure and student withdrawal from university; however, research concerning how social support may influence academic performance in undergraduate students is scarce. This study aimed to examine the relation of different provisions and sources of perceived social support with academic achievement of Spanish university students in their first and third year. The sample consisted of 219 emerging adults, 149 women and 70 men, of average age 18.01 years (SD= 0.46), enrolled on different degree courses at a public Spanish university. Data were collected during the first academic year (time 1) and again during the third academic year (time 2). Regression analysis of the data showed that different dimensions of social support predicted academic success throughout a period of two years. The study findings could be used to help university counsellors and administrators refine programmes and policies aimed at enhancing students’ adjustment and academic achievement.

The results of a longitudinal study on the cognitive development of one group of full-term and three groups of low risk preterm children with different gestational ages (GA) are presented. The 181 participants were divided into four GA groups of similar size. The aims were: 1) To check if there are differences in cognitive development (measured through the Batelle scale) among the GA groups. 2) To establish the predictive factors of cognitive development at 22 and 60 months of age, taking into account biomedical, environmental and individual factors. The results of the repeated measures ANOVA performed at 22 and 60 months of age indicated that the cognitive trajectories of the four GA groups were similar. Linear regression analyses showed that the effect of the different predictors changed in relation to the time of measurement of cognitive development. Biological factors and the quality of home environment had a moderate effect on the cognitive development at 22 months of age. Cognitive results obtained at 22 months of age, and, to a lesser extent, working memory had the greatest effect on cognitive development at 60 months. GA does not predict cognitive development. Preterm children do not show cognitive delay if they are healthy.
