Body image, strategies to change muscles and weight, and puberty: do they impact on positive and negative affect among adolescent boys and girls?

The purpose of this study was to examine the impact of strategies to both decrease weight and increase muscle tone on negative (depression, anxiety) and positive affect among adolescent males and females. The respondents were 1185 adolescents (587 males, 598 females) who were enrolled in grades 7 and 9 (mean age for males=13.22 years; mean age for females=13.21 years). Respondents completed the Body Image and Body Change Inventory that assessed body image satisfaction, body image importance, body change strategies to decrease weight, body change strategies to increase muscle tone, and food supplements. Respondents also completed the Pubertal Development Scale, the depression and anxiety scales of the Depression Anxiety and Stress Scale, and the positive affect items from the Positive and Negative Affect Scale. Structural equation modelling was used to determine how body satisfaction and importance, body change strategies, and puberty impacted on depression, anxiety, and positive affect. The results demonstrated that for both boys and girls, there was a strong association between body change strategies and negative affect. For boys, body dissatisfaction did not predict negative affect, although this was a strong predictor for girls. Body change strategies did not strongly predict positive affect for either boys or girls, although body image satisfaction was a strong predictor for both genders. The implications of these findings for obtaining a better understanding of the role of pubertal development, body image, and body change strategies in predicting positive and negative affect among adolescent males and females are discussed.

Extra relationship involvement among women: are they different from men?

Factors related to three types of Extra Relationship Involvement (ERI) in women were explored: emotional ERI, sexual ERI, and a combination of sexual and emotional ERIs. A model, based on a decision-making model of male ERI and the additional variable of commitment, was evaluated. The research involved two studies with female participants (N = 112, N = 44) who had been involved in heterosexual relationships of at least 6-month duration. The major finding was that women engage in emotional and combined ERIs but rarely enter into solely sexual ERIs. It was demonstrated that social norms, planning, relationship satisfaction, and commitment were influential in predicting emotional and combined ERI intentions. Past ERI behavior was a strong predictor of future emotional and combined ERI behavior, but planning also added to the prediction of combined ERI behavior. Women who had engaged in emotional ERIs and combined ERIs indicated romantic affect as the main reason for their ERI behavior. Overall, it was demonstrated that women's intentions to engage in ERI were related to cognitive processes and relationship variables, and that ERI behavior, although generally habitual, was also predicted by cognitive processes.

Body image and body change methods in adolescent boys. Role of parents, friends and the media.

OBJECTIVE: This study examines sociocultural influences affecting both body image and body change methods in adolescent boys. METHODS: Twenty boys in grade 7 (aged 12-13) and twenty boys in grade 9 (aged 14-15) were individually interviewed. The influence of parents, siblings, friends and the media on both body image and body change methods was evaluated. RESULTS: For approximately a third of the boys, parents, siblings, friends and the media were perceived to have at least some influence over boys' feelings about their bodies and body change methods. In particular, feedback from mothers and female friends were viewed as having a positive impact on boys' body image whereas feed-back from fathers and male friends was viewed as more important in influencing body change methods. The media was also viewed as contributing to boys' body satisfaction but it was seen to encourage greater exercise to alter body size and shape. CONCLUSION: The differences and similarities between the sociocultural messages received by males and females are discussed. The implication of these findings in fostering better health among adolescent males are explored.
