Abstract
BACKGROUND
Assessment of psychomotor symptoms may lead to better classification of depressive disorders.
AIM
To test the inter-rater reliability of the Dutch version of CORE, an observational instrument for psychomotor symptoms.
METHOD
The CORE was used with 37 depressed in-patients and was scored by 5 psychiatrists. Intra-class correlation (ICCagreement) was tested.
RESULTS
ICCagreement of the total score (0.80), and the subscales non-interaction (0.74), retardation (0.70) and agitation (0.79) were sufficient.
CONCLUSION
The Dutch version of the CORE is a reliable instrument.
