The aim of the study was to evaluate the reliability and validity of the Visual Prostate Symptom Score (VPSS), its correlation with the International Prostate Symptom Score (IPSS), and the time required and need for help when completing the instrument. We also aimed to identify variables associated with difficulty completing these instruments.
Longitudinal, prospective correlational study.
The target population was Brazilian men from different cities within the state of São Paulo with lower urinary tract symptoms followed in urological consultation at a university hospital during October 2017. The sample comprised 59 patients with a mean age of 66.53 years.
Reliability of the VPSS was evaluated using a test-retest approach and its convergent validity with the IPSS. Cronbach α coefficient was also calculated. Both questionnaires were self-administered and, in case of difficulty of comprehension, assistance was provided.
Mean completion time of the IPSS was 6.56 minutes and for VPSS was 5.02 minutes. The variables skin color and educational level were associated with the difficulty in completing the IPSS and for comprehending meaning of the VPSS pictograms. Internal consistency evaluated using Cronbach α coefficient was 0.74 for IPSS and 0.15 for VPSS, respectively. Test-retest reliability testing revealed that both instruments had a high intraclass correlation index (>0.75). There was a significant correlation between the health-related quality of life (QoL) scores of the 2 instruments (0.71, P = .0001) and between the total score of each instrument with its corresponding QoL score.
Although time for response of the VPSS was shorter and it demonstrated good test-retest reliability, it more frequently required help to answer. The VPSS showed low internal consistency and low correlation with the IPSS (except for the QoL item).
本研究旨在评估视觉前列腺症状评分（VPSS）的可靠性和有效性、其与国际前列腺症状评分（IPSS）的相关性，以及完成该工具所需的时间和是否需要帮助。我们还旨在确定与完成这些工具困难相关的变量。
纵向、前瞻性相关性研究。
目标人群为来自圣保罗州不同城市的巴西男性，他们在2017年10月于一家大学医院的泌尿外科门诊就诊时出现下尿路症状。样本包括59名患者，平均年龄为66.53岁。
采用重测法评估VPSS的可靠性及其与IPSS的收敛效度。还计算了Cronbach α系数。两份问卷均为自填式，若理解有困难，则提供帮助。
IPSS的平均完成时间为6.56分钟，VPSS为5.02分钟。肤色和教育水平这两个变量与完成IPSS的困难以及理解VPSS象形图的含义有关。使用Cronbach α系数评估的内部一致性，IPSS为0.74，VPSS为0.15。重测可靠性测试表明，两种工具的组内相关指数均较高（>0.75）。两种工具的健康相关生活质量（QoL）评分之间存在显著相关性（0.71，P = .0001），且每种工具的总分与其相应的QoL评分之间也存在显著相关性。
尽管VPSS的回答时间较短且重测可靠性良好，但它更频繁地需要帮助来回答。VPSS显示出较低的内部一致性，且与IPSS的相关性较低（除生活质量项目外）。
