IntroductionOver the years, research has implicated a number of developmental (e.g., pubertal timing), psychological (e.g., self-esteem), and sociocultural (e.g., culturally-defined and transmitted messages regarding attractiveness) factors in the development and maintenance of body image disturbance and related issues in adolescents. In this chapter, we will focus exclusively on sociocultural factors that affect adolescent body image, using the Tripartite Influence Model of body image and eating disturbance as our conceptual framework. We will begin by providing some background information on body image and body image disturbance, and offer an explanation as to why adolescents may be particularly vulnerable to the latter. Then, we will explicate the role of the media in transmitting messages to adolescents regarding culturally defined and encouraged images of attractiveness that suggest that females have thin bodies and males have lean, muscular bodies. Next, we will discuss the direct and indirect influences of parents and peers, including appearance-related teasing and criticism and modeling of eating-and weight-related behaviors, which may serve to reinforce mediatransmitted messages. Finally, we will highlight the role of cultural factors such as acculturation and the connection between body image disturbance and other areas of health.
Body Image and Body Image DisturbanceDefining body image is so "tricky" that Thompson et al. (1999) pointed out the existence of 16 different terms used interchangeably by researchers and clinicians (Table 201.1). The common consensus, however, is that body image is a complex, multidimensional construct
