The purpose of the present study was to develop a measure for functional assertiveness, the Functional Assertiveness Scale (FAS). Functional assertiveness is a new concept of assertiveness that represents a method of appropriate self‐expression. Functional assertiveness is defined as interpersonal communication that occurs when a speaker encounters interpersonal problems that should be resolved or has objectives that should be achieved, and the speaker's message is perceived as appropriate by the listener (Mitamura & Tanaka‐Matsumi, 2010, 2010c). Five studies were conducted in order to develop the FAS. In Study 1, we generated an item pool for FAS, and in Study 2 we developed the FAS prototype using this item pool. Study 3 examined the factorial validity, concurrent validity, and internal consistency of the FAS. Study 4 examined test–retest reliability of the FAS. Study 5 examined responsiveness on the FAS. The validity and reliability of the FAS and potential utility and clinical implication of the FAS are discussed.
