La escala Strength and Difficulties Questionnaire (SDQ) como predictora del TDAH: Comportamiento de las subescalas SDQ respecto a las dimensiones “Hiperactividad/Impulsividad” e “Inatención” en una muestra clínica

Abstract

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.
