Welcome to the 21st WCP Virtual Congress Program Scheduling

Studies in siblings of subjects with ADHD, specifically on psychosocial adversity, have been conducted in developed countries, but there are no known studies in a low/middle-income country, which has different genetic and environmental components. We aim to determine the psychosocial adversity and family characteristics, as potential risk factors associated, in a group of siblings of patients with Attention-Deficit/Hyperactivity Disorder (ADHD), in low/middle-income countries. We will present the results of a multicenter study. We studied siblings of subjects with ADHD with a set of instruments to assess the presence of mental disorders. Rutter indicators of adversity (RIA) were used to measure psychosocial adversity, including low social class, severe marital discord, large family size, paternal criminality, and maternal mental disorder. We will present the most frequent adversity factors in the whole sample and also their role in psychiatric disorders development in the high-risk siblings. Doctor Martinez will present results from the Colombian sample and doctor Palacios-Cruz the Mexican sample. We will present the high prevalence of ADHD in this sibling at risk in a low/middle-income country. It seems that this risk for ADHD is not only determined by a parent with an ADHD history but also by the presence of other environmental and psychosocial factors. We will explain that the best predictor for ADHD in these siblings is to have 3 or more RIA. Attendees will learn about the main psychosocial risk factors for ADHD.
