title: [Reliability of the Neuropsychiatric Inventory-Nursing Homes Polish version].
abstract: OBJECTIVE
  The present study evaluated the reliability of the Neuropsychiatric Inventory-Nursing Homes) (NPI-NH) Polish version.
  
  
  METHODS
  43 nursing home residents fulfilling the ICD-10 criteria for dementia were assessed with NPI-NH.
  
  
  RESULTS
  For analysis of data we used Cronbach's alpha and Spearman's rank correlation coefficients. The internal consistency of the NPI-NH was satisfactory (Cronbach's alpha for the total was 0.25 and only 0.881 for the frequency and severity of symptoms). Spearman's rank correlation coefficients for the test-retest reliability was 0.75 for the total scale results and ranged from 0.40 to 0.85 for each symptom assessed. Interrater reliabilities were 0.86 for the total and from 0.71 to 1.00 for each symptom reported.
  
  
  CONCLUSIONS
  The preliminary results of the Neuropsychiatric Inventory-Nursing Homes Polish version reliability were all satisfactory.
