title: Validation study of PECC (Psychosis Evaluation tool for Common use by Caregivers): Interscale validity and inter-rater reliability.
abstract: BACKGROUND
  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.
  
  
  CONCLUSIONS
  PECC can now be implemented on a large scale. (Int J Psych Clin Pract 2002; 6: 135-140).
