This chapter describes Dynamic Functional Interaction (DFI), a revisionist and sequential theoretical model of adolescent psychological development and behavior. DFI theory explains common problems encountered by adolescents today. Its concepts account for the processes and dynamics of adolescent development. In the DFI model, problem behaviors are defensive actions that occur when the psychological growth tasks of adolescence become too difficult and painful. Practical applications of DFI frame the diagnostic model of defensive glitches, diagnostic protocols, and Peer Arena Lens group therapy. DFI also offers explanations for the functional purpose of most adolescent interactions and how adolescents pursue their quest to reach maturity and attain identity. This chapter also considers Sigmund Freud's structural theory and developmental theory and places adolescent comparison behavior within the theoretical context of adolescent development and behavior.
