An amended version of the SDQ Impact supplement designed to be administered as a stand-alone session-by-session questionnaire.

Focuses on 3 main areas:

  • Change in the recent past: Have things improved since last time?
  • Impact on everyday life at present: To what extent are current difficulties interfering with home life, friendship, learning and leisure?
  • Hope for the future: How much improvement does the respondent anticipate next month?

Psychometric properties 

While the SxS as a stand-alone measure has not yet been tested for psychometric properties, the items it contains are the same as the impact supplement of the full-length SDQ, which has a strong body of research on its validity and reliability. For more detailed information on the psychometric properties of the full SDQ please see here.


Is available in self-report for ages 11-17, and parent/carer report for ages 4-17


We are not currently aware of any non-English versions of this measure. Please contact the measure developer for further information on translated versions.



The measure is intended to be used on a session-by-session basis, and thus can be used at each session, or at less frequent intervals at the discretion of the practitioner.

Scoring and interpretation

The SxS is scored in the same manner as the Total Impact subscale of the full-length SDQ. Instructions for scoring can be found here.
