Validation study of PECC (Psychosis Evaluation tool for Common use by Caregivers): Interscale validity and
Introduction:
PECC (Psychosis Evaluation tool for Common use by Caregivers) is a recently developed tool for the longitudinal evaluation and follow-up of psychotic patients. This integrated evaluation tool covers different functional and symptomatic outcome measures, which are relevant for both the patient and the planning of interventions. PECC was especially designed to be easily implementable in the daily practice of nursing work. In this study we aimed to evaluate the inter-rater and interscale validity of PECC.
Results:
The results indicate that both the inter-rater validity and the interscale validity of PECC are satisfactory.
Conclusion:
PECC can now be implemented on a large scale. (Int J Psych Clin Pract 2002; 6: 135-140).
