The Behavior Identification Form (BIF; Vallacher & Wegner, 1989) was developed as part of a study examining action identification. The BIF was designed to measure individual differences in level of personal agency. Each item on the BIF presents an act identity followed by two alternative identities, one lower and one higher in level; respondents are …
