Strengths and Difficulties Questionnaire (SDQ)

The Strengths and Difficulties Questionnaire (SDQ) is a brief questionnaire for assessing the psychosocial adjustment of children and adolescents. Versions are available for parents and teachers of 4- to 16-year-olds, and a nearly identical version can be completed independently by 11- to 16-years olds. The SDQ differs from related instruments in that it is very short, with 25 items that are divided into five scales: emotional symptoms, conduct problems, hyperactivity-inattention, peer problems and prosocial behavior.

In TRAILS Next, the subscales peer problems and social competence were included.
