The Bystander Behavior (For Friends) Scale: Factor Structure and Correlation With Prior Victimization:

The Bystander Behavior (for Friends) Scale (BBS) offers a promising method of studying prosocial bystander behavior in the context of sexual assault and intimate partner violence. The underlying structure of the BBS has only been studied in the development sample, which was predominantly White and from one university in the Northeast region of the United States. This single sample raises questions about the replicability and generalizability of the factor structure. In addition, confirmatory factor analytic (CFA) methods, which are favored for binary data, were not used in the developmental sample. There also is limited research on individual characteristics that may relate to engagement in different types of bystander behavior. The primary aims of the current study were to (a) use CFA to evaluate the factor structure of the BBS in a sample of university undergraduates recruited from four universities and (b) test associations between prior victimization (general and family-specific) and BBS factors.
