Abstract

This paper has identified five major categories of the T2D patients' concerns based on an online forum where the patients voluntarily verbalized their naturally occurring emotional reactions and concerns related to T2D. We have emphasized the fact that the lexical and phrasal analysis brought to the forefront the prevailing negative reactions and desires for clear information, professional advice, and emotional support. This study used lexical and phrasal analysis based on text-mining tools to estimate the potential of using a large sample of patient conversation of a specific disease posted on the internet for clinical features and patients' emotions. As a result, the study showed that quantitative analysis based on text-mining is a viable method of generalizing the psychological concerns and features of T2D patients.

본 연구는 질병과 관련한 온라인 포럼에서 추출한 언어 데이터를 통해 제 2형 당뇨병 환자의 질병에 대한 담론을 양적으로 분석하였다. 또한 환자 언어행위의 양적분석을 통해 환자들의 주요 관심사와 심리적 특징의 일반화가 가능한지에 대해 실증적으로 검증하였다. 분석방법으로는 기존의 인터뷰에 기반한 정성적 연구방법론과 달리 환자들의 담론 표본 전체를 파싱 (parsing)과 POS 태깅을 통해 언어학적으로 형태소 분류를 하였다. 주요 어휘빈도 추출과 N-gram을 통한 최빈도 구문구조 분석을 병행하여, 질병과 관련한 이슈의 주요 범주와 심리상태에 관한 언어적인 특징을 살펴보았다. 연구 결과 환자들의 자발적 대화는 주로 다이어트, 운동, 증상, 약물치료, 심리상태의 5가지 범주로 나타나고 있음을 확인하였고, 최빈도 구문구조 분석을 통해 질병치료와 식생활습관 개선 전반에 대한 부정적인 견해가 두드러진 것을 확인하였다. 결과적으로 의료진의 정확한 정보 전달과 전문가의 조언, 정서적 지원 등이 당뇨환자에 대한 심리적 상태에 중요한 만큼 심리치료 서비스이 개선이 필요할 것으로 보인다. 이런한 결과는 기존의 의료제도 안에서의 환자의 관심사와 심리적 특징이 온라인 상에서도 적절하게 투영되고 있음을 시사한다.
