The FOF intervention is based on the Information, Motivation, and Behavioral Skills Model (IMB). This theory asserts that HIV-related information, motivation, and behavioral skills are the fundamental determinants of HIV/STD prevention. If an individual is well-informed, motivated to act, and possesses the skills and confidence to take effective action, he or she is more likely to initiate and maintain patterns of HIV/STD preventive behavior.
FOF also draws from Albert Bandura's Social Learning Theory. This theory states that people learn new behavior through observational learning, imitation, and modeling. If people observe positive, desired outcomes in the observed behavior, then they are more likely to model, imitate, and adopt the behavior themselves. FOF utilizes a Peer Health Advisor (PHA) to model correct condom and lubricant use skills. With the PHA's guidance, the clients then imitate those skills to build their self-efficacy for correct and consistent condom use.
