心身互動（mind-body interaction, MBI）係指人的心智、思維、信念與身體反應之間的整體關聯和互動過程，對健康頗具影響，而促成心與身安適是護理維護健康之終極目標。目前雖然有不少的文獻針對MBI的評估與實務應用進行探討，但尚缺整體性的概念分析。因此，本文根據Walker與Avant所提出的概念分析步驟介紹及分析MBI，結果指出MBI的定義特徵為：（1）覺察個人心身作用，（2）出現心理、神經、免疫等系統間之相互作用，以及（3）產生心理、生理、社會狀態之結果。MBI的前因包括地理文化、種族、性別、年齡、教育、專業、價值觀、個性、經歷和健康狀態等。MBI的結果會導向安適、疾病或死亡。期望透過概念分析釐清MBI之意涵，以提供實務照護人員對於MBI有較完整的認識與應用。

Mind-body interaction (MBI) refers the holistic association and interactive process between wisdom, thinking, belief, and physiological reaction, which critically affects health. The main goal of nursing is to maintain mind and body in a healthy state of well being. Few reports in the literatures have addressed the evaluation and application of MBI. Thus, a conceptual analysis of this subject is worth exploring in depth. This paper analyzes the MBI concept step by step based on the procedures of Walker and Avant. The result defines the characteristics of MBI as (1) being aware of psychosomatic effects, (2) interacting between psychology, neurology, immunology and others, and (3) turning out a bio-psycho- social status. Antecedents include geography, culture, race, gender, age, education, profession, values, personality, experience, and health status. Consequences of MBI include well-being, illness, and death. This paper provides new information on MBI that clarifies its meaning, provides comprehensive cognition, and suggests useful applications.
