Introduction

Although body image is a construct critically relevant to human development, it has been studied primarily by clinicians. A recent (December, 2009) literature search in PsycInfo for the key words “body image” produced 7,368 articles, books, chapters, and dissertations addressing this topic. Dating back to 1903, “body image” research originally focused on self-image or self-concept and usually examined samples of mentally retarded or otherwise psychologically ill or impaired individuals’ sense of self (not necessarily their physical body). This early research differs from contemporary body image research in its relatively general approach, psychoanalytic undertones, and scarcity (<1% of body image research was published before 1970). The majority (approximately 90%) of body image research has been published since 1980, paralleling an increase in research addressing eating disorders in the last three decades. What may be most striking is not the relatively recent proliferation of research addressing body image, but the predominantly clinical nature of this research. Of all the body image publications, the vast majority can be found in abnormal, clinical, health/medical, or social/personality journals. Only a minority (<1% it appears) can be found in developmental psychology journals and even fewer are longitudinal studies in peer reviewed journals.

Understandably, interest in body image has come to researchers’ attention most often under conditions of extreme distortion or dissatisfaction. Body dysmorphic disorder, anorexia nervosa, and bulimia nervosa represent psychiatric disorders hallmarked by negative body image. However, the range of normal and pathological body image experiences is broad and has psychological, behavioral, and developmental consequences all along its spectrum (Markey and Markey 2009). Body image is not a static property of an individual and it is not merely an intrapersonal quality. Understanding body image requires understanding how individuals feel about themselves as they inevitably undergo physical changes across the lifespan. It also requires considering the myriad factors that contribute to body image as well as the concurrent and longitudinal consequences of body image. The adolescent years provide a particularly salient example of the developmental significance of body image and the contemporary importance of body image research. What follows is a review of recent and classic research addressing developmental precursors and consequences of body image. Although researchers’ current understanding of body image is complex, developmental scientists’ contribution to this research is necessary so that youths’ body image may be improved.

Pubertal Development and Body Image

The physical development that accompanies the adolescent years is more extensive than that experienced at any other time of life (aside from infancy). Girls’ physical changes that accompany puberty often bring them further from the cultural ideal of beauty with significant weight gain (~25 lbs; Warren 1983). Although different studies suggest the effects of these physical changes vary in severity and importance relative to other factors (e.g., sociocultural influences) in predicting girls’ body image, most reveal puberty as a risk factor for girls’ body dissatisfaction (O’Dea and Abraham 1999). The timing of girls’ pubertal development relative to their peers also appears to be significant, with earlier developers more inclined to gain more weight and most likely to report greater body dissatisfaction (Ackard and Peterson 2001; Archibald et al. 2003). Puberty may present a risk factor for boys’ body image as well (Ricciardelli and McCabe 2003); however, post-pubertal boys tend to have higher body satisfaction than do boys who are pre-pubertal or currently experiencing puberty (O’Dea and Abraham 1999). Developmental research that further addresses adolescents’ ability to cope with pubertal changes and incorporate these changes into a positive body image is needed.

Identity Development and Body Image

Identity development has long been viewed (see Erikson 1968) as a central task of adolescent development. Researchers such as Harter (see 1988, 2003) have described different constructs that contribute to adolescents’ sense of self including academic competence, popularity and social acceptance, romantic appeal, and physical appearance. Relevant to researchers’ understanding of body image development, Harter’s work (e.g., 2001, 2003) suggests that adolescents’ perceptions of their physical appearance contributes most significantly to their overall sense of self. With changing bodies to make sense of, adolescents’ views of their bodies no doubt contribute to their physical appearance self-concepts and their identity (Frost and McKelvie 2004; Rosenblum and Lewis 1999). Research that extends our understanding of the relative importance of different factors (e.g., body satisfaction) to youths’ identity and ways in which the value of these factors may be altered may contribute to efforts to improve both youths’ body image and general sense of self.

Family Relationships and Body Image

Adolescents’ relationships with their family members, particularly their parents, change during this developmental period. These relationship changes are speculated to be linked with physical changes accompanying puberty (see Steinberg 1987) and have the potential to impact parents’ influence on their adolescents’ developing body image (McCabe and Ricciardelli 2003). Specifically, low levels of family expressiveness have been found to predict body dissatisfaction (Babio et al. 2008) and longitudinal research examining both adolescent girls and boys shows a link between parental support deficits and later increases in body dissatisfaction (Bearman et al. 2006). Parents’ influences may be most significant when they are explicit, such as actively encouraging their adolescent to try to lose weight or participate in particular dieting techniques (Benedikt et al. 1998; Wertheim et al. 1999). However, some research suggests that parents may indirectly teach their adolescents to be dissatisfied with their bodies by modeling body dissatisfaction and dieting behaviors (Haines et al. 2008). Developmental researchers could contribute to body image research by addressing ways in which parents can sustain and improve their children’s body image.

Peer Relationships and Body Image

The adolescent years are an important period for the development of peer relationships. Recent research (e.g., Jones and Crawford 2006) suggests the important role peers may play in shaping adolescents’ feelings about their bodies. This research indicates that both adolescent girls and boys talk with their friends about their appearances and changing their appearances (e.g., dieting, muscle building) and peers’ feedback is associated with adolescents’ behavioral attempts to alter their bodies (see Clark and Tiggemann 2006; McCabe and Ricciardelli 2003). Explicit negative feedback from peers in the form of appearance-related teasing has been found to be particularly detrimental to the development of body image and may have long-term consequences for not only body image, but the development of self-concept and interpersonal relationships (Davison and Birch 2002; Eisenberg et al. 2006). Developmental research addressing the potentially positive ways that youths influence each other’s body image and encourage healthy eating and physical activity patterns is needed.

Romantic Relationships and Body Image

Emerging research suggests links between adolescents’ development of romantic relationships, weight status, and body image (Markey and Markey 2009). For example, some research suggests that adolescent girls who are in romantic relationships may be more likely to try to change their bodies via dieting than are their peers who are not in relationships (Halpern et al. 2005). Perceived pressure to be thin from romantic partners has also been associated with body dissatisfaction and disordered eating across time (Shoemaker, personal communication, August 5, 2009). Once in romantic relationships, young men’s and women’s own body satisfaction has been found to be correlated with their perceptions of their romantic partners’ satisfaction with their bodies (Goins and Markey 2009; Markey and Markey 2006). Tantleff-Dunn and Thompson (1995) go as far as to suggest that romantic partners may not only shape body image, but may influence individuals’ vulnerability to disordered eating and their general psychological health. However, some research (e.g., see Markey et al. 2004) hints that romantic relationships may serve a positive role in the development of body image, provided romantic partners communicate supportively about these issues. Future research that addresses the development of body image as a factor in the initiation of romantic relationships and romantic relationships as potential contributors to body image is needed.

Obesity, Eating Disorders, and Body Image

In addition to the nonclinical correlates of body dissatisfaction, consequences of body dissatisfaction includes life-threatening health problems. In particular, obesity is described as a growing “epidemic” that has been linked with body dissatisfaction (Centers for Disease Control and Prevention 2009; World Health Organization 2009). Research seems to clearly suggest that body dissatisfaction and weight concerns are forerunners to dieting and other body-change strategies (Lowe et al. 2006; Markey and Markey 2005; Stice et al. 1999; Tomiyama and Mann 2008). However, the efficacy of most weight-loss approaches is highly questionable, with weight gain being a likely outcome of most attempts to lose weight (Polivy and Herman 2002; Stice et al. 1999). Consistent with these findings is additional research indicating that self-restriction and external attempts to control food intake tend to result in increased food consumption, binge eating, and higher weight status (see Polivy and Herman 2002, for a review). Thus, it appears that body dissatisfaction and related attempts at weight loss may ultimately contribute to obesity (Markey and Markey 2009).

In addition to links between body image and obesity, research has established links between body dissatisfaction and disordered eating. Body dissatisfaction has been found to consistently predict disordered and maladaptive eating behaviors as well as other psychological problems (e.g., clinical eating disorders, depression) among girls (Smolak 2004; Stice and Bearman 2001; Stice and Shaw 2002). In fact, Stice’s meta-analysis (2002) suggests that body dissatisfaction is one of the most significant predictors of disordered eating. Among boys, body image concerns appear to be concurrently associated with dieting, weight loss strategies, low self-esteem, depression, eating disorders, and the adoption of maladaptive body change strategies (e.g., steroid use; see Cafri et al. 2005; McCabe and Ricciardelli 2004). Although less common than obesity (<6% of adolescents are affected), eating disorders represent a significant threat to adolescents’ health and are often referred to as the most deadly of all psychiatric disorders (Hudson et al. 2007). Even though obesity and eating disorders are typically viewed as the terrain of clinical psychologists, collaborations with developmental psychologists may enhance our ability to understand the complex factors contributing to these problems and the inevitably even more complex solutions needed to prevent and treat them.

Conclusion

The above research suggests that body image is related to many issues that psychologists regard as critical to development: puberty, identity, family, peer, and romantic relationships. Significant health concerns, including obesity and eating disorders, are associated with body dissatisfaction. Further, the large number of girls (24–90%) and boys (10–75%)Footnote 1 affected by body dissatisfaction makes it essential that developmental psychologists direct their attention to this area of research (Collins 1991; Jones, personal communication, July 16, 2009; Ericksen et al. 2003; McCabe and Ricciardelli 2004; Neumark-Sztainer et al. 2002; Presnell et al. 2004).

Body image is an important construct for researchers (as well as health care providers and laypersons) to consider even if they are not necessarily concerned with the clinical ramifications of body dissatisfaction. Developmental psychologists are uniquely suited to study body image because of their training and research in topics that overlap with, are correlated with, or represent causes or consequences of body image. In particular, longitudinal research that helps to clarify factors that could help improve adolescent girls’ and boys’ body image should contribute significantly to researchers,’ clinicians,’ and laypersons’ goals of helping young people grow up to become happy and well-adjusted men and women.
