이 연구의 목적은 계획된 행동 이론을 적용하여 사람들의 장기 기증 등록 의도를 이해하고 사회 자본과 대인 커뮤니케이션이 계획된 행동 이론을 매개로 하여 사후 장기 기증 등록 의도에 미치는 영향을 알아보는 데에 있다. 이를 위해 서울 및 수도권 지역에 거주하는 만 20 세 이상의 성인을 대상으로 설문조사를 실시했다. 조사 결과를 토대로 매개 효과를 검증한 결과, 계획된 행동 이론의 요소들을 확장하여, 대인 커뮤니케이션 요소와 사회 자본 요소가 추가된 새로운 연구 모형을 제시하였다. 이는 계획된 행동 이론의 구성 요소들이 형성되는 인과관계를 설명함과 동시에 계획된 행동 이론이 인간의 행위가 이상적인 의사 결정 행위라는 것을 지나치게 강조하고 사회적인 요소를 배제한 이론이라는 비판을 극복할 수 있는 발견이다. 특히 심리학에 기반을 둔 계획된 행동 이론을 사회학 및 커뮤니케이션학 연구 변수들과 접목함으로써 학제간 연구로서의 의의를 지닌다.

The goal of this study is to articulate the effect of social capital and interpersonal communication on the intention of posthumous organ donation by mediating the theory of planned behavior. As for the verification for mediating effects of TPB between interpersonal communication and registering intention, partial mediating effects of subjective norm between the quality of communication and registering intentions and partial mediating effects of attitude were demonstrated. As for the verification for mediating effects of TPB between social capital and intention, full mediating effects of subjective norm and partial mediating effects of attitude were demonstrated. And partial mediating effects of social capital between the amount of communication and intention were found. Judging from the research results, this present study suggest the expanded model of the theory of planned behavior. This model could overcome the criticisms of its asocial conceptualization and the rational decision-making approach. While previous studies about organ donation concentrated mostly on family communication and mass communication, this study suggested the significance of interpersonal communication. Finally, this study have practical implication for the guideline on campaign planning.
