Objective : This study aims to compare the awareness of adolescent occupational therapy (AOT) among university students majoring in occupational therapy (OT) in Korea and the United States through an online survey. Methods : This online survey was conducted from January 9 to 13, 2023 to investigate the awareness about AOT among 55 students majoring in OT in Korea and the United States. An online survey was formulated in Korean and English. Data analysis was performed using descriptive statistics and an independent t-test. Results : In response to the question “Have you ever heard of AOT?”, 65.5% of Korean students answered yes and 58.2% of the United States students answered no. In both countries, the average score for the question “Can AOT help improve the quality of life of teenagers?” was the highest, while the score for “Is AOT sufficiently advanced in your country?” was the lowest. For “Potential for future development of AOT,” the scores for the two countries showed a significant difference (p < .05). Conclusion : Students in both countries acknowledged the necessity and importance of AOT, but there were differences noted in terms of prospects of the therapy.
