SDQ: Predictive Algorithm

A computerised algorithm predicts child psychiatric diagnoses from the symptom and impact scores derived from Strengths and Difficulties Questionnaires (SDQs) completed by parents, teachers and young people. The predictive algorithm generates "unlikely", "possible" or "probable" ratings for four broad categories of disorder, namely conduct disorders, emotional disorders, hyperactivity disorders, and any psychiatric disorder.

At present, the algorithm runs in three statistical packages:

In SPSS statistical software
In SAS statistical software
In STATA statistical software
