In total, 367 patients completed the Turkish HPMDQ and IPSS forms. Of
these, 103 patients met the inclusion criteria, and their Turkish HPMDQs
and IPSSs were evaluated. Of the participants, n = 55 (52.3%) suffered
from PMD (Q1≥1) and n = 48 (45.7%) were found to be completely dry. The
demographic data and clinical findings of the participants are
summarised in Table 1. For the HPMDQ, Cronbach’s alpha was 0.903, mean
inter-item correlation was 0.727 an intraclass correlation coefficient
was 0.903 (CI 95%: 0.869-0.931) (Table 2).
No significant difference was found between the test and retest scores
for the Turkish HPMDQ; the responses to each item mostly overlapped. The
Turkish translation of this questionnaire thus has medium to good
reliability. While the kappa coefficient for the individual item scores
was 0.628–0.838, it was 0.789 for the total score for the Turkish HPMDQ
(Table 3). The relationship between the HPMDQ and the IPSS, which is the
most widely used tool for the evaluation of LUTS, was also investigated.
Considering the concurrent validity, it was observed that the HPMDQ’s
total score correlated significantly with that of the total IPSS (ρ:
0.660, p < 0.001), the voiding symptoms of the LUTS (ρ:
0.621, p < 0.001), and post-void residual volume (ρ:
0.614, p < 0.001) but not with the storage symptoms of
the LUTS (p=0.245). The mean value of HPMDQ-Q5, evaluating the treatment
response of bulbar urethra massage, was 1.81+1.02, suggesting an
effective treatment of PMD.
