    Raw data from the study. This study aimed to develop a measure of assertiveness, the Assertiveness Skills Scale (ASS). Assertiveness is the attitude of a person toward himself and other people, which means treating oneself and others with equal respect and regard for the rights. Assertiveness serves to increase self-satisfaction and good relationships with those around you. Four studies were conducted to develop the ASS. In Study 1., we generated an item pool for the ASS and established its internal structure using Principal Component Analysis (PCA). In Study 2., we confirmed the internal structure of the ASS using the Confirmatory Factor Analysis (CFA). Study 3. examined the convergent and discriminant validity of the ASS. Study 4 examined test–retest reliability of the ASS. The psychometric properties of the ASS and the potential utility of the ASS are discussed.
