{Abstract}: BACKGROUND: ChatGPT has been tested in many disciplines, but only a few have involved hearing diagnosis and none to physiology or audiology more generally. The consistency of the chatbot's responses to the same question posed multiple times has not been well investigated either. This study aimed to assess the accuracy and repeatability of ChatGPT 3.5 and 4 on test questions concerning objective measures of hearing. Of particular interest was the short-term repeatability of responses which was here tested on four separate days extended over one week.
METHODS: We used 30 single-answer, multiple-choice exam questions from a one-year course on objective methods of testing hearing. The questions were posed five times to both ChatGPT 3.5 (the free version) and ChatGPT 4 (the paid version) on each of four days (two days one week and two days the following week). The accuracy of the responses was evaluated in terms of a response key. To evaluate the repeatability of the responses over time, percent agreement and Cohen's Kappa were calculated. Results: The overall accuracy of ChatGPT 3.5 was 48-49%, while that of ChatGPT 4 was 65-69%. ChatGPT 3.5 consistently failed to pass the threshold of 50% correct responses. Within a single day, the percent agreement was 76-79% for ChatGPT 3.5 and 87-88% for ChatGPT 4 (Cohen's Kappa 0.67-0.71 and 0.81-0.84 respectively). The percent agreement between responses from different days was 75-79% for ChatGPT 3.5 and 85-88% for ChatGPT 4 (Cohen's Kappa 0.65-0.69 and 0.80-0.85 respectively).
CONCLUSIONS: ChatGPT 4 outperforms ChatGPT 3.5 both in accuracy and higher repeatability over time. However, the great variability of the responses casts doubt on possible professional applications of both versions.
