title: [Validity and reliability of a questionnaire to assess patients' satisfaction for home care].
abstract: OBJECTIVE
  Specific instruments to measure patients satisfaction for home care are missing in Italy. A questionnaire was devised, based on two well known and validated instruments (La Monica-Oberst Patient Satisfaction Scale (LOPSS) and the The Patient Satisfaction With Health Care Provider Scale (PSHCPS) and validated.
  
  
  METHODS
  The questionnaire was discussed with nurses and psychologists. The questionnarie was initially administered to a sample of 25 patients home care patients, not cognitively impaired, and to their caregivers. The concordance was measured with the K di Cohen, Sperman tau of Cograduation and tau of Kendall coefficiencies, with very satisfactory results (K = 0.68, p = 0.72, tau = 0.61). After 30 days the questionnaire was administered to the same patients and relatives, to test stability/reliability and internal coherence. Finally, it was administered to a stratified sample of 139 patients (or to their relatives) to assess validity with factorial analysis, and again internal coherence.
  
  
  RESULTS
  The final questionnaire has 20 closed ended and three open questions. Concordance between patients and relatives on closed questions was good, therefore the questionnaires can be administered to patients or relatives. The test retest showed also a good stability (K 0.83). The factorial analysis identified two sub scales: one that measures patients satisfaction for the organization and for the interpersonal relationship between patients and nurses.
  
  
  CONCLUSIONS
  The questionnaire has good psychometric properties and can be reliably administered also to caregivers. Some questions with higher number of missing answers could be improved.
