Objective  To revise the of Perceived Rehabilitation Needs Questionnaire for Schizophrenia Patients (PRNQ-S) and to examine the reliability and validity of the revised questionnaire of Chinese version (PRNQ-S-V).

  Methods  We adopted Perceived Rehabilitation Needs Questionnaire for Schizophrenia Patients-Hong Kong Version (PRNQ-S-HK) and conducted cultural modifications for the PRNQ-S-HK with Delphi method. Then we carried out a survey among 236 stable schizophrenia patients randomly selected in a psychiatry outpatient department of a hospital in Changsha city of Hunan province between January and May, 2016 to evaluate the reliability and validity of PRNQ-S-V.

  Results  For the revised PRNQ-S-V, totally 75 items were retained and 17 factors were extracted via factor analyses, which could explain 78.96% of the total variance. Inter-scale correlation studies showed that the correlation coefficients between items and the total score of the questionnaire ranged from 0.377 to 0.768; the correlation coefficients among the 17 factors ranged from 0.348 to 0.620; and the correlation coefficients between each factor and the total score of the questionnaire ranged from 0.498 to 0.833. All of the correlation coefficients were statistically significant (P < 0.01 for all). The Cronbach's α of the PRNQ-S-V was 0.975; the Cronbach's α for each factor of the revised questionnaire ranged from 0.752 to 0.920. The overall Guttman split-half coefficient of the PRNQ-S-V was 0.912 and the Guttman split-half coefficients for each of the factors were between 0.706 and 0.909.

  Conclusion  The revised PRNQ-S-V is of good reliability and validity.
