The effect of body image threat on smoking motivation among college women: Mediation by negative affect.

A recent experimental study found that activation of negative body image cognitions produced urges to smoke in young women (E. N. Lopez, D. J. Drobes, J. K. Thompson, & T. H. Brandon, 2008). This study intended to replicate and extend these experimental findings by examining the role of negative affect as a mediator of the relationship between body dissatisfaction and smoking urges. Female college smokers (N = 133) were randomly assigned to a body image challenge (trying on a bathing suit) or a control condition (evaluating a purse). State levels of urge to smoke, mood, and body dissatisfaction were assessed both pre- and postmanipulation. Trying on a bathing suit increased body dissatisfaction and reported urges to smoke, particularly those urges related to reducing negative affect. Additionally, state negative affect mediated the relationship between the body image manipulation and smoking urge. This study provides additional support, through an experimental design, that situational challenges to body image influence smoking motivation and that this effect occurs, at least in part, through increases in negative affect. Theoretical and applied implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Externalized self-perceptions, self-silencing, and the prediction of eating pathology.

Gender role socialization models posit that the greater prevalence of problematic eating patterns in girls and women is partly due to a socialization process whereby women are taught to view themselves in relation to others, to avoid confrontation, and to conform to societal ideals regarding thinness. This study explored the relationship of these factors to eating pathology. 236 undergraduate women (aged 18-24 years) completed measures related to body image (body dissatisfaction, weight status, perceived importance of shape and weight), relational variables shaped by differential gender role socialization (externalized self-perceptions, self-silencing behaviors and attitudes), and disturbed eating cognitions and behaviors. Perceived importance of shape and weight and externalized self-perceptions were found to predict maladaptive eating-related cognitions, and self-silencing predicted bulimic behaviors when body-related variables were controlled. Thus, it appears that externalized self-perceptions and self-silencing are indeed related to eating disturbances, although further research is needed to demonstrate a causal role for these variables in the development of eating disorders.

A prospective test of the dual-pathway model of bulimic pathology: Mediating effects of dieting and negative affect.

Because there have been few longitudinal investigations of integrative etiological theories of bulimia nervosa, this study prospectively tested the dual-pathway model using random regression growth curve models and data from a 3-wave community sample of adolescent girls (N?=?231). Initial pressure to be thin and thin-ideal internalization predicted subsequent growth in body dissatisfaction, initial body dissatisfaction predicted growth in dieting and negative affect, and initial dieting and negative affect predicted growth in bulimic symptoms. There was prospective evidence for most of the hypothesized mediational effects. Results are consistent with the assertion that pressure to be thin, thin-ideal internalization, body dissatisfaction, dieting, and negative affect are risk factors for bulimic pathology and provide support for the dual-pathway model.

Organizational citizenship behavior and workplace deviance: The role of affect and cognitions.

To investigate the role of affect and cognitions in predicting organizational citizenship behavior (OCB) and workplace deviance behavior (WDB), data were collected from 149 registered nurses and their coworkers. Job affect was associated more strongly than were job cognitions with OCB directed at individuals, whereas job cognitions correlated more strongly than did job affect with OCB directed at the organization. With respect to WDB, job cognitions played a more important role in prediction when job affect was represented by 2 general mood variables (positive and negative affect). When discrete emotions were used to represent job affect, however, job affect played as important a role as job cognition variables, strongly suggesting the importance of considering discrete emotions in job affect research.

Women's body satisfaction at midlife and lifetime body size: A prospective study.

The relationship between past body size and current body dissatisfaction among 933 middle-aged women from a prospective birth cohort study was examined. Women provided self-report data on weight esteem at age 54. Height and weight data were collected at ages 7, 11, 15, 20, 26, 36, 43, and 54. Data on reproductive variables were also collected prospectively. Hierarchical linear modeling and multiple regression analyses were used. Women who were dissatisfied at midlife were heavier at age 7 and showed a more rapid increase in body mass index with age. A late menarche, being postmenopausal, and having started hormone replacement therapy before menopause were associated with less dissatisfaction. Attention to these factors across the life span is necessary to understand body dissatisfaction in women at midlife. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Dissonance and healthy weight eating disorder prevention programs: Long-term effects from a randomized efficacy trial.

Adolescent girls with body dissatisfaction (N = 481, SD = 1.4) were randomized to a dissonance-based thin-ideal internalization reduction program, healthy weight control program, expressive writing control condition, or assessment-only control condition. Dissonance participants showed significantly greater decreases in thin-ideal internalization, body dissatisfaction, negative affect, eating disorder symptoms, and psychosocial impairment and lower risk for eating pathology onset through 2- to 3-year follow-up than did assessment-only controls. Dissonance participants showed greater decreases in thin-ideal internalization, body dissatisfaction, and psychosocial impairment than did expressive writing controls. Healthy weight participants showed greater decreases in thin-ideal internalization, body dissatisfaction, negative affect, eating disorder symptoms, and psychosocial impairment; less increases in weight; and lower risk for eating pathology and obesity onset through 2- to 3-year follow-up than did assessment-only controls. Healthy weight participants showed greater decreases in thin-ideal internalization and weight than did expressive writing controls. Dissonance participants showed a 60% reduction in risk for eating pathology onset, and healthy weight participants showed a 61% reduction in risk for eating pathology onset and a 55% reduction in risk for obesity onset relative to assessment-only controls through 3-year follow-up, implying that the effects are clinically important and enduring.

Predictors of changes in weight esteem among mainland Chinese adolescents: A longitudinal analysis.

Weight and body image concerns are prevalent among adolescents across cultures and pose significant threats to well-being, yet there is a paucity of longitudinal research on samples living in non-Western and developing countries. This prospective study assessed the extent to which select sociocultural, psychological, and biological risk factors contributed to changes in weight esteem among adolescent girls and boys living in the People’s Republic of China. Students (181 boys, 320 girls) from middle schools and high schools in Southwest China completed measures of demographics; weight esteem; thin female and lean, muscular male appearance ideals; positive and negative affect; and appearance-based social pressure, teasing, and comparison. Subsequently, weight esteem was reassessed 18 months later. Girls having stronger preferences for thin ideals, a high body mass index, and more negative affect at Time 1 were more likely to experience losses of weight esteem at follow-up. Among boys, high baseline levels of appearance pressure contributed to later reductions in weight esteem—an effect that was also moderated by age. For both sexes, appearance social comparisons also contributed to weight esteem changes in univariate analyses, albeit these effects were attenuated within multivariate prediction models. In sum, this study highlights how specific experiences implicated previously in research on body dissatisfaction in Western samples are also salient in understanding changes in weight esteem for adolescent girls and boys in rapidly developing China.

Cognitive appraisals and problem-directed coping: A prospective study of stress.

Information-seeking and problem-directed coping behaviors following a stressful event were observed as a function of cognitive appraisals of the coping resources of 138 undergraduates. Subjectively defined failure on a college exam served as an example of a mild stressor. Prior to the 1st midterm exam, Ss generated alternative strategies that could be used in the event of dissatisfaction with performance and rated the feasibility of using these strategies. Academic coping behaviors were measured by self-report and direct observation during the 3 wks prior to the next exam. Results show that coping cognitions predicted academic behaviors but not exam scores. (25 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Relative Importance of Three Domains of Positive and Negative Social Exchanges: A Longitudinal Model With Comparable Measures.

Researchers have expressed considerable interest in the question of whether positive or negative social exchanges more strongly affect psychological health, but previous studies have been limited by using nonparallel measures of positive and negative social exchanges, by measuring negative affect only, and by relying largely on cross-sectional designs. The independent effects of positive and negative exchanges on both positive and negative affect were examined in a short-term longitudinal study of 277 older adults, using social exchange measures with parallel content and equivalent reliability and validity. In cross-sectional analyses, positive exchanges predicted positive affect, and negative exchanges predicted negative affect. In longitudinal analyses, however, negative exchanges predicted both positive and negative affect, whereas positive exchanges were unrelated to either outcome. The more potent and longer-lasting effects of negative exchanges have important implications for theory and interventions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Do positive thinking and meaning mediate the positive affect—Life satisfaction relationship?

The authors tested whether positive cognitions mediated the relationships between positive affect and both meaning in life and life satisfaction, and whether meaning in life partially mediated the relationship between positive cognitions and life satisfaction, among 232 students and community-dwelling adults. Also tested was an alternative model in which positive affect mediated the relationships between positive cognitions and both meaning in life and life satisfaction, and in which meaning in life partially mediated the relationship between positive affect and life satisfaction. Supporting hypotheses and the literature, positive cognitions mediated the relationship between positive affect and meaning in life, and meaning in life partially mediated the relationship between positive cognitions and life satisfaction. Together, positive affect and positive cognitions accounted for 48% of the variance in meaning in life, and the model accounted for 62% of the variance in life satisfaction.

On the role of positive and negative affectivity in job performance: A meta-analytic investigation.

Although interest regarding the role of dispositional affect in job behaviors has surged in recent years, the true magnitude of affectivity's influence remains unknown. To address this issue, the authors conducted a qualitative and quantitative review of the relationships between positive and negative affectivity (PA and NA, respectively) and various performance dimensions. A series of meta-analyses based on 57 primary studies indicated that PA and NA predicted task performance in the hypothesized directions and that the relationships were strongest for subjectively rated versus objectively rated performance. In addition, PA was related to organizational citizenship behaviors but not withdrawal behaviors, and NA was related to organizational citizenship behaviors, withdrawal behaviors, counterproductive work behaviors, and occupational injury. Mediational analyses revealed that affect operated through different mechanisms in influencing the various performance dimensions. Regression analyses documented that PA and NA uniquely predicted task performance but that extraversion and neuroticism did not, when the four were considered simultaneously. Discussion focuses on the theoretical and practical implications of these findings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The causal effects of emotion on couples' cognition and behavior.

The authors conducted 2 translational studies that assessed the causal effects of emotion on maladaptive cognitions and behaviors in couples. Specifically, the authors examined whether negative emotions increased and positive emotions decreased partner attributions and demand-withdraw behaviors. Study 1 (N=164) used video clips to assess the effects of emotion on individuals' attributions. Study 2 (N=47 couples) was a therapy analogue study intended to assess whether emotion generated from couples' conversations would influence subsequent attributions and behaviors. Results indicate that participants in the negative emotion conditions tended to attribute more blame to their partners and were more likely to engage in demand-withdraw patterns and other negative behaviors than were those in the positive emotion conditions. Implications for research and practice are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Eating-Disordered Behaviors, Body Fat, and Psychopathology in Overweight and Normal-Weight Children.

This study examined eating-disordered pathology in relation to psychopathology and adiposity in 162 non-treatment-seeking overweight (OW) and normal weight (NW) children, ages 6-13 years. Participants experienced objective or subjective binge eating (S/OBE; loss-of-control eating), objective overeating (OO), or no episodes (NE). OW children experienced significantly higher eating-disordered cognitions and behaviors than NW children and more behavior problems than NW children: 9.3% endorsed S/OBEs, 20.4% reported OOs, and 70.4% reported NEs. OW children reported S/OBEs more frequently than did NW children (p = .01), but similar percentages endorsed OOs. S/OBE children experienced greater eating-disordered cognitions (ps from     

Interpersonal predictors of dieting practices among married couples.

The relations between couples' marital quality and dieting behavior were examined. One-hundred eighty-seven married couples' dieting behaviors, marital quality, body mass index, weight concerns, depression, and self-esteem were assessed. Results indicate that the relation between healthy dieting behaviors and marital quality is similar for both husbands and wives. However, among wives, marital discord predicted unhealthy dieting behaviors, even after wives' body mass index, weight concerns, self-esteem, and depression were controlled for. Furthermore, wives' self-esteem interacted with marital quality when predicting unhealthy dieting. These findings suggest gender differences in the relations between marital quality and dieting behaviors and are consistent with previous research suggesting that men and women have differential response patterns to marital disharmony, with women tending to internalize negative affect experienced in their marriage.

Are body dissatisfaction, eating disturbance, and body mass index predictors of suicidal behavior in adolescents? A longitudinal study.

Disordered eating, body dissatisfaction, and obesity have been associated cross sectionally with suicidal behavior in adolescents. To determine the extent to which these variables predicted suicidal ideation and attempts, the authors examined these relationships in a longitudinal design. The study population included 2,516 older adolescents and young adults who completed surveys for Project EAT-II (Time 2), a 5-year follow-up study of adolescents who had taken part in Project EAT (Time 1). Odds ratios for suicidal behaviors at Time 2 were estimated with multiple logistic regression. Predictor variables included Time 1 extreme and unhealthy weight control behaviors (EWCB and UWCB), body dissatisfaction, and body mass index percentile. Suicidal ideation was reported by 15.2% of young men and 21.6% of young women, and suicide attempts were reported by 3.5% of young men and 8.7% of young women. For young women, suicidal ideation at Time 2 was predicted by Time 1 EWCB. The odds ratio for suicide attempts was similarly elevated in young women who had reported EWCB at Time 1. These odds ratios for both suicidal ideation and suicide attempts remained elevated even after controlling for Time 2 depressive symptoms. In young men, EWCB was not associated with suicidal ideation or suicide attempts 5 years later. Body mass index and body dissatisfaction did not predict suicidal ideation or suicide attempts in young men or young women. These results emphasize the importance of EWCB.

Magazine exposure: Internalization, self-objectification, eating attitudes, and body satisfaction in male and female university students.

Investigated the relationships among magazine exposure, self-objectification, body shape dissatisfaction, and eating disorder symptomatology in 150 men and women (aged 18-42 yrs). Women reading beauty magazines and men reading fitness magazines internalized societal ideals (internalization). For women, beauty magazines predicted self-objectification, mediated by internalization. For men, only internalization predicted self-objectification. For men, fitness magazines predicted body shape dissatisfaction, mediated by internalization. For women, only internalization predicted body shape dissatisfaction. Reading magazines also predicted eating problems for men and women, for women this was mediated by internalization. Findings suggest that magazine reading is related to concerns with physical appearance and eating behaviors. Many of the relationships previously found for women are similar for men. A sociocultural model is used to explain these results. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sociocultural factors and the development of disordered eating: A longitudinal analysis of competing hypotheses.

Sociocultural models hypothesize causal paths in the development of eating disorders, yet few longitudinal studies have controlled for temporal stability, leaving open the question as to causality and the directionality of effects. In the present study, the authors tested portions of the socioculturally based dual-pathway model, specifically, the risk factor hypotheses that internalization of the thin ideal predicts body dissatisfaction, that body dissatisfaction predicts depressive affect, and that depressive affect predicts disordered eating. The authors also examined competing hypotheses (e.g., disordered eating predicts depressive affect) as well as the possibility of simultaneous relationships (i.e., variables would be related to one another within a time frame). The 6 models (3 cross-lagged and 3 simultaneous) were evaluated using 236 female freshmen who provided self-report data during their 1st semester in college and 6 months later. While controlling for temporal stability, structural equation modeling revealed that (a) internalization and body image each were related to the other across time; (b) body image was related directionally, but only in the simultaneous context, to depressive affect; and (c) depressive affect and disordered eating were related reciprocally and temporally to one another. Directions for future research and implications for intervention are provided. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Prospective relations of body image, eating, and affective disturbances to smoking onset in adolescent girls: How Virginia slims.

This study tested whether body image, eating, and affective disturbances prospectively predicted onset of cigarette smoking in adolescent girls (N=496). Elevated body dissatisfaction and eating pathology, as well as elevated negative affectivity, showed significant univariate relations to subsequent onset of smoking. In the multivariate model, the effect for body image and eating disturbances remained significant, but the effect for negative affectivity did not. Results support the theory that body image and eating disturbances markedly increase risk for smoking initiation in adolescent girls and further establish the clinical significance of these disturbances. Results also support the theory that negative affect is a risk factor for smoking initiation but suggest that the self-medication model may have less predictive power than previously concluded.

Increasing body satisfaction of body concerned women through evaluative conditioning using social stimuli.

Objective: Many women show weight and body concerns that leave them vulnerable to body dissatisfaction, lowered self-esteem, psychological distress, and eating disorders. This study tested whether body satisfaction could be increased by means of evaluative conditioning. Design: In the experimental condition (n = 26), women with low and high body concern completed a conditioning procedure in which pictures of their bodies were selectively linked to positive social stimuli (pictures of smiling faces). Pictures of control bodies were linked to neutral or negative social stimuli (neutral and frowning faces). In a control condition (n = 28), low and high body concerned women underwent a procedure in which pictures of their own body and of control bodies were randomly followed by positive, neutral, and negative social stimuli. Main Outcome Measures: Changes in body satisfaction and self-esteem before and after the conditioning task. Results: Women with high body concern demonstrated an increase in body satisfaction and global self-esteem when pictorial representations of their own bodies were associated with positive stimuli that signaled social acceptance. Conclusion: A simple conditioning procedure increased body satisfaction in healthy, normal weight women who were concerned about their shape and weight.

Disordered eating and unhealthy weight reduction practices among adolescent females

BACKGROUND: Dissatisfaction with body weight and the use of unhealthy weight reduction practices have been reported among adolescent females. There is a need for methodologically rigorous studies using large representative samples of adolescent females to accurately assess the prevalence of these behaviors and attitudes. METHODS: Eight hundred sixty-nine Australian school girls ages 14-16 years were administered a self-report questionnaire to determine the prevalence of disordered eating behaviors, unhealthy dieting practices, and distorted body image. Anthropometric (height and weight) data were collected on each of these adolescent females. RESULTS: The prevalences of disordered eating, unhealthy dieting, and distorted body image were 33, 57, and 12%, respectively. Over one-third (36%) of the total sample had used at least one "extreme" dieting method in the past month, i.e., "crash" dieting, fasting, slimming tablets, diuretics, laxatives, and/or cigarettes to lose weight. Of the total sample, 77% wanted to lose weight and 51% had tried to lose weight in the past month. Motivating factors for disordered eating and unhealthy dieting behaviors were peer pressure, media pressure, and the perception that extreme dieting strategies were harmless. CONCLUSION: The prevalence of disordered eating and dieting behaviors among adolescent females shown by this study suggests the need for preventive programs encouraging appropriate eating and dieting behaviors.
