General Description

The SIB-S uses two scales applied to the same 25 items in order to evaluate the discomfort felt when required to act assertively and the frequency with which one acts assertively. Moreover, each one of these scales considers four contexts of assertive performance: expression of negative feelings (i.e., 7 items), expression and management of personal limitations (i.e., 6 items), taking initiative (i.e., 6 items), and expression of positive feelings (i.e., 6 items). Its Portuguese version was validated using a community adolescent sample aged 16 to 21 years old.
