The existing array of evidence-based body image prevention and intervention approaches has evolvedover time. However, the majority originated directly or indirectly from a cognitive-behavioral conceptu-alisation of body image pioneered by Thomas F. Cash. In this way, it is difficult to overstate the impactTom Cash has had on body image intervention research and practice. His ground-breaking work, buildingon the work of Schilder and Fisher, was the first to provide a comprehensive model of body image thatreflected the broad range of influences and consequences of body image. His differentiation of the com-ponents of body image as a construct and between body image traits and states allowed us to identifyand influence targets for intervention. Moreover, the intervention strategies that Tom Cash employed arestill used today and laid the foundations for contemporary intervention programs. There is a gap of morethan 15 years between the first and last of us receiving our PhDs, yet Cash’s work has been an importantinfluence on us all. We are extremely grateful for the theoretical and practical tools that he has given toour field. In this paper, we will outline how Cash’s work has informed contemporary body image inter-vention and prevention. We will describe Cash’s theory and intervention tools before discussing how thiswork paved the way for subsequent research and practice.
