Strengths and Difficulties Questionnaire - Parent (SDQ-Parent) and Impact Supplement (SDQ-Parent-Impact) - Lebanon

​​ML guidance 2The Strengths and Difficulties Questionnaire (SDQ) is a brief screen for child psychiatric disorders designed for children aged 4-17, with subscales measuring emotional problems, conduct problems, hyperactivity, peer problems, and prosocial behaviour. There is also an Impact Supplement that measures distress and impairment due to emotional and behavioural problems.

Evidence Snapshot

In testing, there was limited evidence for internal consistency of subscales and for the hypothesized subscale structure. Nonetheless, the total difficulties score and the externalizing score showed reasonable ability to discriminate between children with disorders (any common mental disorder and externalizing disorders, respectively) and those without. The internalizing scale performed poorly and the subscale score is not recommended as a way to screen for internalizing disorders in this context.
