PURPOSE
To validate a paper-based visual acuity (PBVA) questionnaire.
METHODS
In 2015, a cross-sectional survey was conducted among 301 young and middle-aged, mostly male, Japanese subjects. The participants were asked to self-rate their visual acuity (VA) on a scale from 1 to 5. Self-ratings of VA were categorized into three groups: good (1 and 2), normal (3), and poor (4 and 5). For objective validation, we performed a functional VA (FVA) assessment in the same subjects.
RESULTS
A total of 301 subjects answered the PBVA and completed the FVA test including initial VA. We found out that the result of PBVA was significantly correlated with FVA test and initial VA (=0.33, <0.0001, =0.273, <0.0001). The trend test analysis between PBVA and FVA also showed statistically significant (<0.0001).
CONCLUSION
There was a significant statistical correlation between the PBVA and the FVA, as well as the initial VA. This short questionnaire on VA might be a sensitive tool that is easy to implement and utilized in large epidemiological and clinical researches.
目的
验证一份纸质视力（PBVA）问卷。
方法
2015年，对301名日本中青年受试者（大多数为男性）进行了横断面调查。要求参与者在1至5的量表上对自己的视力（VA）进行自评。VA自评分为三组：良好（1和2）、正常（3）、差（4和5）。为进行客观验证，我们对同一受试者进行了功能性视力（FVA）评估。
结果
共有301名受试者回答了PBVA问卷并完成了包括初始视力在内的FVA测试。我们发现PBVA结果与FVA测试及初始视力显著相关（=0.33，<0.0001，=0.273，<0.0001）。PBVA与FVA之间的趋势检验分析也显示具有统计学意义（<0.0001）。
结论
PBVA与FVA以及初始视力之间存在显著的统计学相关性。这份简短的视力问卷可能是一种敏感工具，易于在大型流行病学和临床研究中实施和应用。
