Dear Bruno,

I wonder if these articles are of interest to you:

• Using the Strengths and Difficulties Questionnaire (SDQ) to screen for child psychiatric disorders in a community sample by Robert Goodman.
• Eating disorders in children and adolescents. First results of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) by H. Hölling & R.Schlack. [Article in German].
• The hyperactivity/inattention subscale of the Strengths and Difficulties Questionnaire predicts short- and long-term weight loss in overweight children and adolescents treated as outpatients by A. van Egmond-Froehlich, M. Bullinger and others.

Best wishes,

Stephen
