Methods An extended I-PSS questionnaire (with questions on four other voiding symptomsadded to the standard I- PSS) was administered to 204 men aged 57-72 in a retrospective investigation. Then ina following prospective investigation, the subjects were asked to carefully observe and record daily for 4 weeks theirurinary conditions for questions listed on the I- PSS. Finally, the individually matched-pair data from theretrospective and prospective investigation were compared and analyzed, and the differences in the paired datawere tested for their statistical significance. Results The differences in the mean scores of 8 matched -pair itemsamong the total 13 items in the two investigations are found to be statistically significant, with all of the meanscores from the prospective investigation being lower than those from the retrospective one. The mean differences forthe 8 items in the two investigations range from 0.12 to 1.29 points. The mean differences for the total scores(I-PSS) is 0.87 points and its standard deviation is 4.07 points. Those subjects whose symptom categories werechanged in the two investigations account for 23.5% of the total 204 subjects and those whose total scores (I-PSS)were changed account for 89.7%. The results of this comparative study show that the percentage rates ofcorrectness, overestimate and underestimate of the data collected from the retrospective investigation are 22.1, 45.1and 32.8 respectively. A medium - level correlation exists between corresponding scores of all items in the twoinvestigations. Conclusion The data obtained from I-PSS in retrospective investigation diverges substantiallyfrom the actual conditions of respondents in most cases.展开更多
