Life Satisfaction and Violent Behaviors among Middle School Students

We explored relationships between violent behaviors and perceived life satisfaction among 2,138 middle school students in a southern state using the CDC Middle School Youth Risk Behavior Survey (MSYRBS) and the Brief Multidimensional Student Life Satisfaction Scale (BMSLSS). Logistic regression analyses and multivariate models constructed separately revealed significant race by gender results. Odds ratios and 95% confidence intervals were calculated for the variables of interest. Having ever carried a gun, ever carried a knife/club, physical fighting and physical fighting with need for medical treatment were associated (p ≤ .05) with reduced life satisfaction for specific race/gender groups, while controlling for SES and grade. Results suggest implications for school-community based violence prevention programs. Future research should consider measures of life satisfaction as a component of comprehensive assessments of middle school student violence and aggressive behaviors in fieldwork, intervention research and program evaluation.     

Similar stimulus features control visual classification in orangutans and rhesus monkeys

Many species classify images according to visual attributes. In pigeons, local features may disproportionately control classification, whereas in primates global features may exert greater control. In the absence of explicitly comparative studies, in which different species are tested with the same stimuli under similar conditions, it is not possible to determine how much of the variation in the control of classification is due to species differences and how much is due to differences in the stimuli, training, or testing conditions. We tested rhesus monkeys (Macaca mulatta) and orangutans (Pongo pygmaeus and Pongo abelii) in identical tests in which images were modified to determine which stimulus features controlled classification. Monkeys and orangutans were trained to classify full color images of birds, fish, flowers, and people; they were later given generalization tests in which images were novel, black and white, black and white line drawings, or scrambled. Classification in these primate species was controlled by multiple stimulus attributes, both global and local, and the species behaved similarly.     

Relationships amongst body dissatisfaction, internalisation of the media body ideal and perceived pressure from media in adolescent girls and boys

Sociocultural factors that underpin gender differences in body dissatisfaction have not frequently been explored. We examined the relative contribution of internalization of media body ideals and perceived pressure to achieve this ideal in explaining body dissatisfaction in adolescent boys and girls. A sample of 819 boys and 791 girls completed measures of internalization of body ideals, perceived pressure, body mass index (BMI) and body dissatisfaction. As expected, girls showed higher body dissatisfaction, internalization and pressure than boys. Internalization, pressure and BMI contributed to the prediction of body dissatisfaction in boys and in girls although these variables explained less variance in body dissatisfaction in boys. In addition, for girls the strongest predictor of body dissatisfaction was internalization, whilst for boys the strongest predictor was pressure. Differences in extent of internalization and pressure may contribute to higher body dissatisfaction in girls than boys. These sociocultural factors may affect girls and boys differently.     

Is BodyThink an efficacious body image and self-esteem program? A controlled evaluation with adolescents

This study aimed to evaluate the efficacy of BodyThink, a widely disseminated body image and self-esteem program. Participants were 277, grade 7 students from 4 secondary schools in Australia. The intervention group (62 girls, 85 boys) participated in BodyThink during four 50-min lessons, while the control group (65 girls, 65 boys) received their usual classes. All participants completed baseline, postintervention and 3-month follow-up questionnaires. For girls, the intervention group reported higher media literacy and lower internalization of the thin ideal compared to the control group. For boys, the intervention group reported higher media literacy and body satisfaction than the control group. Although some positive outcomes were observed, it would be valuable to find ways to enhance the impact of BodyThink, especially in light of its wide dissemination. Suggestions for improving BodyThink are presented.     

An exploration of the tripartite influence model of body dissatisfaction and disordered eating among Australian and French college women

The aim of the study was to compare levels of body dissatisfaction, disordered eating and risk factors, and to examine the tripartite influence model of body image and eating disturbance among French and Australian young adult females. Participants were 188 Australian (mean age=19.6 years, SD=1.0) and 190 French (mean age=20.7 years, SD=2.6) students. Media, peer and family influences, internalisation of media ideals, appearance comparison, body dissatisfaction, drive for thinness, bulimia and self-esteem were assessed. Australian participants reported perceiving more peer and media influence, and higher levels of appearance comparison, internalisation of media ideals and bulimic symptoms than French participants (p<.001). Path analyses revealed that the tripartite model was a good fit in both samples, with similarities and differences. Findings suggest the importance of identifying cultural specificities, and developing a global framework of body image and eating disturbance with a view to prevention.     

Examination of a model of multiple sociocultural influences on adolescent girls' body dissatisfaction and dietary restraint

This study examined the perceived role of three types of sociocultural agents (peers, parents, and media) in influencing body dissatisfaction and dietary restraint in adolescent girls. Participants were 577 grade 10 girls from six schools who completed questionnaires in class and had height and weight measured. Two path analyses resulted in a similar pattern. While current body size strongly predicted ideal body size and body dissatisfaction, perceived influence of multiple sociocultural agents regarding thinness also had a direct relationship with body ideal and dissatisfaction. Dietary restraint was predicted directly from body dissatisfaction and sociocultural influences. Peers, parents, and media varied in their perceived influence. The findings support the idea that those girls who show the most body dissatisfaction and dietary restraint live in a subculture supporting a thin ideal and encouraging dieting.     

Test-retest reliability and construct validity of Contour Drawing Rating Scale scores in a sample of early adolescent girls

Test–retest and construct validity of Contour Drawing Rating Scale (CDRS) scores were examined in 1056 Grades 7 and 8 girls. Questionnaires were completed four times, including retests at 2, 6 and 14 weeks. Test–retest reliability for current size, ideal size and current–ideal discrepancy mostly exceeded 0.70 (0.65–0.87, for the full sample, with higher rs for shorter retest periods). Ideal and current size ratings increased slightly over time. High correlations between perceived current figure and measured body mass index; moderate rs between current–ideal discrepancy and body dissatisfaction and restrained eating; and very low or no significant correlations with social desirability supported construct validity in this group. The study supported the use of the CDRS in early adolescent girls.     

Prolonging the effects of deposit contracts with smokers

Three group-comparison studies are reported which investigate possible ways of prolonging the effectiveness and increasing the acceptability of deposit contracts with smokers. In Experiment 1 deposits held for a total of 4 months were compared with those lasting 2 months. In Experiment 2 a ‘reinforcement thinning’ procedure in which the intervals between deposit repayments are progressively increased was compared with contracts involving equal intervals between repayments. In Experiment 3 the effects on compliance, drop-out rates and treatment outcome of a cumulative-deposit procedure were studied. Subjects in this condition were asked to supply a deposit in 4 weekly instalments rather than as a lump sum. The results of Experiments 1 and 2 were disappointing. There were no significant differences between treatments, although there was a trend in favour of ‘thinning’ deposits. Experiment 3, however, showed that the cumulative-deposit procedure was effective in influencing more subjects to provide deposits. Neither drop-out rate nor treatment outcome was adversely affected. It is difficult for a straightforward reinforcement model to account for these results. Other models are discussed, and ways of testing them suggested. A larger study is still needed to determine whether certain deposit-contract procedures can add to the long-term effectiveness of behavioural-package programmes for stopping smoking.     

Examination of a multi-factorial model of body-related experiences during pregnancy: the relationships among physical symptoms, sleep quality, depression, self-esteem, and negative body attitudes

The aim of this cross-sectional study was to investigate relationships among women's body attitudes, physical symptoms, self-esteem, depression, and sleep quality during pregnancy. Pregnant women (N = 215) at 15–25 weeks gestation completed a questionnaire including four body image subscales assessing self-reported feeling fat, attractiveness, strength/fitness, and salience of weight and shape. Women reported on 29 pregnancy-related physical complaints, and completed the Beck Depression Inventory, Rosenberg Self-esteem Scale, and Pittsburgh Sleep Quality Index. In regressions, controlling for retrospective reports of body image, more frequent and intense physical symptoms were related to viewing the self as less strong/fit, and to poorer sleep quality and more depressive symptoms. In a multi-factorial model extending previous research, paths were found from sleep quality to depressive symptoms to self-esteem; self-esteem was found to be a mediator associated with lower scores on feeling fat and salience of weight and shape, and on higher perceived attractiveness.     

Effects of parental comments on body dissatisfaction and eating disturbance in young adults: A sociocultural model

This study examined a sociocultural model of the influence of parental comments on body shape and eating concerns among males and females. Questionnaires were completed by 338 undergraduates. Participants reported levels of perceived parental comments, internalization of media ideals, appearance comparison, body dissatisfaction, drive for thinness and bulimia. Results revealed that, regardless of gender, internalization and appearance comparison only partially mediated the relationship between parental comments and the outcome variables. The final model for females explained a larger proportion of the variability in body shape and eating concerns than in males, with positive and negative parental comments directly related to body dissatisfaction and through it to eating outcomes. In males, only negative comments were directly related to body dissatisfaction. These findings highlight the role of parental influences in sociocultural models of the development of body dissatisfaction and eating concerns, and the gender-specific patterns of sociocultural influence.
