Primary: Development and functioning Secondary: General mental health assessment
Social and psychiatric functioning.
To assess a child or adolescent's lowest level of social or psychiatric functioning in a specified time period.
This measure may be used to assess current level of social/psychiatric functioning in children and adolescents, or to establish a baseline level of functioning prior to implementing an intervention or treatment program.
Global functioning is assessed on a scale from 1 to 100, broken down into 10 equal parts. The measure describes the level of functioning represented by each decile.
20-30 minutes
Raters must be clinicians familiar with behavioural rating scales and the administration and interpretation of psychological measures.
The child is rated on a scale of 1 to 100, with lower scores indicating greater impairment. The authors suggest that scores above 70 indicate normal functionality. Interpretation should be done by clinicians familiar with the administration and interpretation of psychological measures.
The norms, reliability and validity statistics included in each measure profile are those reported by the author(s) of the measure. It is important to note that altering, adding or removing questions from a measure voids these reported statistics, possibly making the revised tool unreliable and invalid.

The authors report an inter-rater reliability of 0.84, and a test-retest reliability of 0.85. Further studies have found inter-rater reliabilities ranging from 0.53 to 0.92.
The authors report evidence of discriminative validity. Further studies have found evidence of discriminant validity, minimal divergent validity, and mixed convergent validity.
