VARIABLE(S) MEASURED: Global impairment for children and adolescents

PURPOSE:
Designed as a measure of global impairment that can be administered by trained lay-persons and used in large-scale population surveys.

DESCRIPTION/DEVELOPMENT:
The CIS is a 13-item scale which tap four major areas of functioning: interpersonal relations, broad psychopathological domains, functioning in job or schoolwork and use of leisure time.  The CIS has both parent and child versions.

SUBJECTS: The scale was tested on a sample of 182 children aged 9-17 years.

ADMINISTRATION:
The CIS can be administered by lay interviewers and provides a respondent-based rating that is independent of the clinical judgement.

SCORING:
Items are scored on a Likert scale ranging from 0 (no problem) to 4 (very big problem). The total score can range from a minimum of 0 to a maximum of 52.

RELIABILITY:
1. Internal consistency: Parent CIS :.85 to .89; Child CIS: .70 to .78.
2. Test-retest reliability (mean interval is 14.7 days): Parent CIS:.89; Child CIS: .63.

VALIDITY:
The correlation between the Parent CIS and the clinicians CGAS (Children Global Assessment Scale) was -.73, while the Child CIS was -.48.
