SDQ (Strengths and Difficulties Questionnaire)

The Strengths and Difficulties Questionnaire (SDQ) is a clinically validated emotional and behavioural screening questionnaire which can be used with all ages.

Research has shown that it is a reliable and valid tool. It is concise and easy to use and it gives a score that indicates when difficulties may be present.

Scores are added together to produce a total overall difficulties score. The questionnaire then asks for the impact of the behaviour to be rated to determine whether it is chronic, how much distress it causes, the level of social impairment and the burden to others.

The information gathered will be used as:

- An indicator to track the levels of difficulties the individual is experiencing and any improvements that are made

- A guide for putting in place the appropriate support services

The form has 5 separate subscales for different aspects of problems or behaviours some positive others negative:

  • Emotional problems
  • Conduct problems
  • Hyperactivity
  • Peer problems
  • Prosocial behaviours
