Relationship between Illness Perception and the need for Professional Medical Interpretation for International Patients in Japan

This study aimed to conduct a cross-sectional questionnaire survey of foreign patients to analyze the impact of patients’ illness perceptions on their need for professional medical interpreters. From February 2022 to May 2023, an online questionnaire was distributed to 4,962 individuals aged 18 years or older who were non-native speakers of Japanese. These individuals were enrolled in organizations such as international exchange associations and Japanese language support classes and had utilized medical institutions in Japan due to their own illness or injury or that of their children. Among the 312 valid responses, international patients with a high score for illness perception were more likely to want to utilize professional medical interpreters than those with a low score for illness perception (odds ratio, 1.968; 95% confidence interval, 1.044–3.709; P = 0.036). Our findings suggest that hospitals should be better prepared to meet the potential language needs of international patients with a higher illness perception.
