Introduction: Strength and Difficulties Questionnaire (SDQ) is an international screening tool widely used for research and clinical practice on child and adolescents. Objective: The aim of this study was to explore the relationship between SDQ indices and “Hyperactivity/Impulsivity" and "inattention" domains of specific ADHD scale. Method: The SDQ and ADHD-RS-IV were administered to parents and teachers of a sample of 212 children aged between 6 and 16 years old with a prior diagnosis of ADHD. Results: A significant relationship between "Hyperactivity/inattention" Scale (SDQ) and "hyperactivity/impulsivity" and "inattention" ADHD dimensions was confirmed. However, other SDQ scales were also related, depending of informant and ADHD domain. For the family, "hyperactivity/impulsivity" domain was related with high scores on "behavior problems" scale, while the "inattention" was related with "emotional symptoms" scale. Conclusions: This results suggest the possibility of to take into account rating scores on SDQ scales to increase the sensitivity of the scale to discriminate ADHD clinical subtypes The underwater environment is an extreme environment that requires a process of human adaptation with specific psychophysiological demands to ensure survival and productive activity. From the standpoint of existing models of intelligence, personality and performance, in this explanatory study we have analyzed the contribution of individual differences in explaining the adaptation of military personnel in a stressful environment. Structural equation analysis was employed to verify a model representing the direct effects of psychological variables on individual adaptation to an adverse environment, and we have been able to confirm, during basic military diving courses, the structural relationships among these variables and their ability to predict a third of the variance of a criterion that has been studied very little to date. In this way, we have confirmed in a sample of professionals (N = 575) the direct relationship of emotional adjustment, conscientiousness and general mental ability with underwater adaptation, as well as the inverse relationship of emotional reactivity. These constructs are the psychological basis for working under water, contributing to an improved adaptation to this environment and promoting risk prevention and safety in diving activities.
El medio subacuático constituye un entorno extremo que exige un proceso de adaptación humana con demandas psicofisiológicas especí-ficas para garantizar la supervivencia y la actividad productiva. En este trabajo explicativo se analiza, bajo la óptica de los actuales modelos de inteligencia, personalidad y rendimiento, la contribución de las diferencias individuales para explicar la adaptación de personal militar en un entorno estresante. Se verifica, mediante análisis de ecuaciones estructurales, un modelo donde se contemplan los efectos directos de las variables psicológicas sobre la adaptación personal a un medio adverso, comprobando sus relaciones estructurales durante la realización de cursos básicos de buceo militar y su capacidad para predecir un tercio de la varianza de un criterio poco estudiado. De esta manera, se confirma en una muestra de profesionales (N = 575) la relación directa de ajuste emocional, responsabilidad y habilidad mental general con la adaptación subacuática, atribuyendo una relación inversa a reactividad emocional. Estos constructos constituyen el fundamento psicológico para desenvolverse con seguridad y trabajar bajo el agua, contribuyen a la mejora de la adaptación al medio subacuático y favorecen la prevención de riesgos y la seguridad en las actividades de buceo.
