VARIABLES MEASURED: Psychiatric symptoms and their severity

PURPOSES: To detect the changes in treatment

DESCRIPTION/DEVELOPMENT :
The comprehensive psychopathological is designed to measure changes in psychopathology over a comparatively short period.

This rating scale covers 65 psychopathological variables which are selected from a wide range of psychiatric signs and symptoms drawn from clinical experience.  In the scale, an explicit description of each item is provided.

The severity of each symptom is operationally defined on a 3-point scale.  The dimensions used for ranging the severity are intensity, frequency, and duration of the symptom.

The scale can be used in whole or in part.  The number of items included in the scale may vary depending on the project for which the rating is used.

SUBJECTS: The scale is tested among a group of depressive patients.

ADMINISTRATION:
This scale can be used by all trained mental health workers.  Training for interviewer is required in using the scale because clinical judgment is involved.  The duration of the interview will partly depend on the number of items selected, but the initial interview will most often take about an hour.

SCORING:
Each item of the scale is rated on a 3-point scale.  The total severity of the illness is the sum of scores on each item related to this illness.

RELIABILITY:
Interrater reliability of the severity of depression (17-item) is assessed.  The correlation among psychiatrist general practitioner, psychiatrist psychologist, and psychiatrist nurse ranges from .33 to .99.

VALIDITY:
The criterion validity of severity of depression is assessed against Hamilton Rating Scale.  The correlation between 10-item depression scale and HRS are .70 and .67 in two tests.

COMMENTS: This scale is in file.
