ABSTRACT

Objective The aim of the present study is to evaluate the reliability and validity of the Mandarin version of the PP (MPP) .Methods The first step in the establishment was to translate the original English version into mandarin version with the method of cross -culture translation .The reliability was performed with the internal consistency analysis and test -retest reliability .The validity was performed for the content validity and structure va-lidity .The samples were from 80 Chinese CI children ,and 43 parents answered this questionnaire again 1 month lat-er to evaluate the test -retest reliability .The average age at cochlear implantation were 26 ± 14 months ,ranging from 7 months to 68 months ,the average duration of CI use were 10 ± 7 months ,ranging from 0 month to 24 months .Results The reliability analysis indicates that the Cronbach'sαcoefficient was 0 .797 ,except for the well-being and happiness ,education ,whose coefficients are respectively 0 .303 ,and 0 .341 ,all of the other sundomainscoefficient were greater than 0 .5 ,indicating the internal consistency was good .Test -retest reliability of the scale Cronbach'sαwas satisfactory .All subdomains and total score of the scale coefficients were greater than 0 .70(P<0 .01) .The validity analysis indicated that the pearson correlation coefficients among the total scale and the 8 subdo-mains were 0 .395~0 .992 ,the correlation coefficients among each subdomains were 0 .09~0 .654 ,which confirmed with the psychological characteristics ,proving its good structure validity .Conclusion The Chinese version of the PP show s good reliability and validity and can be used to evaluation the quality of life in mandarin CI children.
