BackgroundWhile fluid intelligence has proved to be central to executive functioning, logical reasoning and other frontal functions, the role of this ability in psychosocial adaptation has not been well characterized.Methodology/Principal FindingsA random-probabilistic sample of 2370 secondary school students completed measures of fluid intelligence (Raven's Progressive Matrices, RPM) and several measures of psychological adaptation: bullying (Delaware Bullying Questionnaire), domestic abuse of adolescents (Conflict Tactic Scale), drug intake (ONUDD), self-esteem (Rosenberg's Self Esteem Scale) and the Perceived Mental Health Scale (Spanish adaptation).Lower fluid intelligence scores were associated with physical violence, both in the role of victim and victimizer. Drug intake, especially cannabis, cocaine and inhalants and lower self-esteem were also associated with lower fluid intelligence. Finally, scores on the perceived mental health assessment were better when fluid intelligence scores were higher.Conclusions/SignificanceOur results show evidence of a strong association between psychosocial adaptation and fluid intelligence, suggesting that the latter is not only central to executive functioning but also forms part of a more general capacity for adaptation to social contexts.

Identificar factores instruccionales específicos relacionados con progresos en comprensión lectora es esencial para optimizar el aprendizaje y orientar la intervención, especialmente en contextos de desventaja sociocultural o dificultades de aprendizaje. Este estudio pretende identificar patrones instruccionales de mediación eficaces en la explicación del progreso en comprensión. Se grabaron, transcribieron y analizaron sistemáticamente 82 sesiones-clase, y se registraron pautas de mediación relativas a diferentes procesos lectores. Los patrones de mediación fueron analizados mediante codificación y categorización del contenido con el programa Maxqdea-7. Fueron consideradas 19 categorías, que aglutinaron 178 unidades de información significativas (pautas/conductas de mediación). La muestra estuvo compuesta por 21 docentes y 821 estudiantes de tercero a octavo grado de Educación básica de escuelas públicas de Chile ubicadas en contextos deprivados. El progreso lector se midió con la prueba estandarizada CL-PT, aplicada al principio y al final del curso escolar. Los resultados permitieron identificar pautas específicas de mediación significativas en la explicación del progreso, especialmente el patrón M_17 (Mediación del uso de estrategias para la activación e integración de conocimientos previos) explicaba el 26% de la varianza (r = .55, p < .01; R2ajustado = .26, F(1, 19) = 8.19, p = .01). Se discuten las implicaciones educativas de estos resultados.    Identifying specific instructional factors related to progress in reading comprehension is essential to optimize learning and guide intervention, especially in contexts of sociocultural disadvantage or learning difficulties. This study aims to identify effective mediational instructional patterns in the explanation of progress in reading comprehension. Teaching guidelines were systematically recorded in relation to different reading processes. Eighty-two sessions were recorded, transcribed and analyzed by coding and categorizing the content of the sessions through the Maxqdea-7 program. Nineteen categories were considered, which comprised 178 significant units of information (mediation guidelines). The sample consisted of 21 teachers and 821 students from third to the eighth grade of public schools of Chile located in deprived contexts. Reading progress was measured with the standardized CL-PT test, which was applied at the beginning and end of the school year. The results have allowed identifying mediation patterns with a significant relevance in the explanation of reading progress, especially the pattern M_P17 (Mediation of the use of strategies for the activation and integration of previous knowledge) managed to explain 26% of the variance in the progress (r = .55, p < .01; R2adjusted = .26, F(1, 19) = 8.19, p = .01). The educational implications of these results are discussed.
