“…The sample consisted of adolescents who had been attributed a diagnosis according to the ICD 10 of psychotic disorders in 25.4% of cases, personality disorders in 34.3% (20.9% of them as a single diagnosis, 13.4% with comorbidities), behavioral disorders in 11.9%, phobias, stress-related and somatoform disorders in 10.4%, mental retardation in 9.0% and affective syndromes in 9.0% (Table 1) No statistically significant differences emerged between males and females in relation to the diagnosis ICD 10 (χ 2 = 9.72, df = 6, p exact = n.s.). These data do not confirm the literature on psychopathology in developmental age, in which gender variables are reportedly highly significant; for instance, psychosis, somatization, depression and eating disorders all have a different, gender-related prevalence and incidence (Costello et al, 2006;Frigerio et al, 2009;Kessler & Wang, 2008). It is well known that problems of aggressive behavior, mental retardation and psychosis are more frequent in males, while eating disorders and internalizing disorders are more common among females.…”
