Abstract:
Objective To develop suitable hand hygiene questionnaire for maintenance hemodialysis (MHD) patients and test its reliability and validity,so as to prepare for the next stage of investigations and interventions.Methods Documentary,focus group discussion and expert-consulting methods were used to help formulate the questionnaire.300 MHD patients were collected by systematic sampling to test its reliability and validity.50 MHD patients were chosen randomly for validating analysis after a month.Results The last questionnaire included 5 dimensions:consciousness of washing hands,indication of washing hands,knowledge about hand hygiene and correct methods of washing hands,factors of patients' unwillingness to wash hands and methods of washing hands,with 34 items.The Cronbach' s αcoefficient of the questionnaire was 0.972,and the coefficient of 5 dimensions was respectively 0.813,0.909,0.846,0.853 and 0.898.All 34 articles of the questionnaire were determined by exploratory factor analysis,and the value of the KMO was 0.807,the approximate x2 value of Bartlett's spherical inspection was 1282.117,with statistical significance (P ＜0.01).The accumulative contribute rate of 6 common factors whose eigenvalue exceeded 1 was 69.41％.Validating analysis showed that no difference was found between scores of all items,and the test-retest reliability of r was greater than 0.8 with good reliability.Conclusions The reliability and validity of hand hygiene questionnaire for maintenance hemodialysis patients are good enough to reach the standard of formulation,which can be used an effective tool to measure the hand hygiene of MHD patients to some extent.
