Aim:
To detect attention deficit hyperactivity disorder (ADHD) in children between 4 and 14 years of age by means of the Questionnaire for screening Latin American schoolchildren and adolescents for ADHD (QLSA-ADHD) and the criteria of the Diagnostic and statistical manual of mental disorders, fourth edition, ADHD version (DSM-IV ADHD).
Patients And Methods:
A prospective, cross-sectional, analytical study was conducted to detect ADHD in the child population that visited the outpatient department at the Rodolfo Nieto Padron Children's Hospital. These children were administered two surveys: the DSM-IV ADHD and the QLSA-ADHD. The results were analysed using graphs and test statistics from the SPSS package, such as the correlation coefficient and chi squared.
Results:
The questionnaires were analysed by finding the overall sum of the criteria of the 200 children included in the DSM-IV ADHD and the average score values were found to be 64 'yes' (32%) and 137 'no' (68%). The QLSA-ADHD was evaluated in the same way and the average was 50 'yes' (25%) and 149 'no' (75%). The chi squared test was then performed for the two, the result being 1.762, with 1 degree of freedom and p > 0.05; that is to say, there was no significant difference between the scores obtained in both surveys. With the QLSA-ADHD, 25% of children with ADHD were detected, whereas the figure rose slightly to 25.5% (51 patients) with the DSM-IV. The chi squared test was conducted between the results from the two surveys, the value being 3.405, with 1 degree of freedom and p > 0.05.
Conclusions:
Our findings show that, in our population, there is no difference between the QLSA-ADHD and the DSM-IV for detecting ADHD.
