The objective of this study was to complete a teacher questionnaire on a sample of children (N = 232) in nine fourth grade classes in schools in two regions of central Italy to assess the frequency of occurrence of symptoms of attention-deficit hyperactivity disorder (ADHD) and the rates of probable cases in the sample.
Each ADHD symptom was rated by the teacher as either absent (0), sometimes present (1) or frequently present (2).
Of the children 3.9% had eight or more DSM-III-R Criterion A symptoms of ADHD scored at a "frequent" level (score of 2) and were considered to be "likely cases" of ADHD; an additional 6.9% did not meet this threshold but had a total score of 16 or more on the scale and were considered to be "possible cases."
The findings suggest the need for more systematic epidemiological investigations to evaluate the true prevalence of the syndrome and its risk factors in the Italian population.
