    The Kidney Transplant Questionnaire (KTQ) is a quality-of-life instrument designed specifically for renal transplant recipients.
    The purpose of this work was to evaluate the validity and reliability of a Persian translation of the KTQ-25 questionnaire as a tool for use in Iran and also to compare the quality of life between dialysis and transplant patients.
    We collected 143 subjects in a cross-sectional study. Their mean age was 40.3±13.3 years (range=15-72). All KDQ-25 scales met the criteria for internal consistency(Cronbach's alpha ranged from 0.8-0.95) and in construct validity, the correlation coefficient between 5 scales and the total scale was also acceptable (0.84-0.91). Furthermore, significant correlations were detected between the scales (P<.001).
    The mean total score was 2.8±1.4 (range=5.8-1.5). The best mean score observed in uncertainty and fear item was 3.1±1.6 (range=0.5-7), while the lowest was detected in the emotional item, 2.4±1.3 (range=0.17-6). Mean follow-up was 50.1 (range=1-264) months. The most common physical problem was aching, tired legs in 77 (55%) subjects.In comparison between dialysis and transplant patients using the standard Iranian version of Kidney Disease Quality of Life (KDQOL) questionnaire, the total and disease-specific scores for dialysis patients were significantly better than the total score in the KDQ-25 (55.8±14 vs 40.7±20.2, P=.000) and (49.7±15.8 vs 40.7±20.2, P=.000), respectively.
    Considering its validity and reliability, the Persian version of KTQ-25 questionnaire may be useful to assess the health-related quality of life among Iranian transplant recipients.
