导盲鞋可以帮助盲人在日常生活中身心健康。他们的资格取决于健康、工作表现和气质；大约 70% 不合格的木鞋因行为原因而被取消资格。为了实现资格的早期预测，第一步必须确定导盲犬的重要气质特征。因此，我们对经验丰富的训练师进行了一份包含22个气质项目的问卷，以在三个月的训练后对日本导盲犬协会的候选犬进行评估，这距离最终的成功（作为导盲犬资格）或失败（因行为原因被取消资格）判断至少三个月之前。对问题项进行因素分析，稳定提取出三个内部一致性较高的因素：Distraction、Sensitivity、Docility。当我们比较成功的狗和失败的狗之间的因素点时，成功的狗表现出显着且一致的较低分心点和较高的顺从点。此外，分心点可以以 80.6% 的准确率预测资格，并检测出 28.2% 的失败狗的分心点高于任何成功狗。在三个因素中未包含的九个问题项目中，有两个项目（“攻击性”和“动物兴趣”）始终与资格相关。这些结果表明，分心是可以稳定评估的，并且对成功或失败判断的影响最大；因此，建立可以早期预测导盲犬资格的行为测试将是第一个目标。
Guide clogs for the blind help blind people physically and mentally in their daily lives. Their qualifications are based on health, working performance and temperament; approximately 70% of clogs that fail to qualify are disqualified for behavioral reasons. In order to achieve early prediction of qualification, it would be essential as the first step to identify important temperament traits for guide dogs. Therefore, we administered a questionnaire consisting of 22 temperament items to experienced trainers to assess candidate dogs at the Japan Guide Dog Association after three months of training, which was at least three months prior to the final success (qualified as a guide dog) or failure (disqualified for behavioral reasons) judgment. Factor analyses of question items stably extracted three factors with high internal consistency, Distraction, Sensitivity and Docility. When we compared factor points between successful dogs and failed dogs, the successful dogs showed significantly and consistently lower Distraction points and higher Docility points. Additionally, Distraction points could predict qualification with 80.6% accuracy and detect 28.2% of the failed dogs that had higher Distraction points than any of the successful dogs. Of the nine question items not included in the three factors, two items ('Aggression' and 'Animal interest') were consistently associated with qualification. These results suggest that Distraction is stably assessable and has the strongest impact on success or failure judgment; therefore, it will be the first target to establish a behavioral test that may lead to early prediction of guide dog qualification.
