Self-Awareness, Task Failure, and Disinhibition: How Attentional Focus Affects Eating

ABSTRACT Dieting and nondieting subjects were given either failure or neutral performance feedback on a problem-solving task. Failure subjects were then assigned to one of three self-awareness conditions: One group was forced to watch a video clip of themselves failing on the problem-solving task, one group was asked to watch a distracting video clip on bighorn sheep, and the final group was asked to sit quietly for 10 minutes. Subjects were then allowed to eat as much ice cream as they wanted. Only in those conditions which allowed—or promoted—low self-awareness (the failure/distraction and simple failure condition) did dieters show disinhibited eating. In the failure/videotape condition, which enforced high levels of self-awareness, eating in dieters remained inhibited. This supports the proposal that a reduction in self-awareness is necessary for lifting of inhibitions. Eating in nondieters was reduced in the failure/videotape and simple failure conditions, possibly because of the autonomic correlates of distress.     

Relations among weight control behaviors and eating attitudes, social physique anxiety, and fruit and vegetable consumption in Turkish adolescents

This study examined the relationship among dieting, eating attitudes, social physique anxiety, and fruit and vegetable consumption among Turkish adolescents. Abnormal eating behavior (EAT-26 > or =20) was found in 32.8% of the total sample; this included 26.4% of the males and 38.7% of the females. Weight-control and weight-related behaviors are associated with high fruit and vegetable consumption in adolescents. Dieting was significantly associated with types of consumption in female adolescents. In addition, EAT-26 scores were significantly positively correlated with high fruit and vegetable consumption, but this association was not observed in SPAS scores among adolescents. Adolescents who engage in dieting behaviors seem to consume more fruit and vegetables than do other adolescents. Female adolescents may be more likely to display abnormal eating attitudes and dieting behaviors than do males. Although some weight-control behaviors may be risky, adolescents who were practicing dieting behaviors engaged in the positive dietary behavior of consuming more servings of fruit and vegetables than did non-dieters.     

The Effects of a List of Food Items on Motivations to Eat in Dieters and Nondieters

A major health problem in our society is obesity, which is frequently caused by overeating or eating inappropriate foods. It has been suggested that the prevalences of food and food-related cues contribute to overeating and that dieters are particularly sensitive to food stimuli. In the present study, the influence of dieting was examined in a representative sample of college students who were exposed to a list of written food cues or who served as controls. The list of food cues increased motivation to eat in nondieting subjects, but did not appear to influence the appetites of dieters. It may be that dieters are more resistant to the effects of more subtle food cues, even when many cues are presented sequentially.     

The effects of self-attention and public attention on eating in restrained and unrestrained subjects

Two experiments were conducted to assess the effects of self-attention and public attention to food intake on eating by dieters and nondieters. Female dieters ate the greatest number of candies ad lib after consuming a forced two-milk shake preload; the addition of either self-attention or implied public attention, through the manipulated availability of a waste basket for the disposing of candy wrappers, inhibited eating substantially. For nondieters, the preload itself inhibited candy consumption, which declined further only under conditions of public attention to candy intake. In a second experiment, self- and public attention again inhibited the cookie consumption of preloaded dieters, but preloaded nondieters were not influenced by the attention manipulations, eating minimally in all conditions. Nondieters who were not preloaded, however, did reduce their intake in the two attention conditions. Implications for regulatory self-control were discussed.     

Through the eyes of dieters: Biased size perception of food following tempting food primes

Why do some dieters succeed in controlling their diet while others do not? This research focused on a perceptual process—size perception of food objects—that may moderate the success of dieters in self-control dilemmas. We assessed successful and unsuccessful dieters' size perception of palatable food (Study 1) and diet-food (Study 2) after pre-exposing them to tempting food primes. Dieters perceived palatable food as bigger when primed with tempting food (vs. control prime), regardless of self-regulatory success in dieting (Study 1). Palatable food thus looms larger for both unsuccessful and successful dieters when in a “hot” state. In contrast, the perceived size of diet-food was increased by a tempting food prime only for successful dieters, but decreased for unsuccessful dieters (Study 2). These results are interpreted in terms of differences in the mental accessibility of competing goals (eating enjoyment vs. dieting) in successful vs. unsuccessful dieters. Indeed, when the dieting goal was made accessible for all dieters by a diet prime, even unsuccessful dieters perceived diet-food as bigger (Study 2). This research provides insight into a perceptual process that may be detrimental or beneficial in resolving self-control conflicts in the domain of eating and dieting behavior—and probably other domains of self-control as well.     

Psychological characteristics of dieters and bulimics.

Two studies examined the continuum and discontinuity models of the relation between dieting and bulimia nervosa. In Study 1, 21 dieters, 19 bulimics, and 33 nondieting controls were compared on 24 measures. Multivariate analyses revealed that each of the groups differed significantly from the other two. Univariate analyses found 18 significant differences between bulimics and dieters and 1 significant difference between dieters and controls. In Study 2, 86 subjects completed measures of psychological functioning, dieting, and bulimia nervosa. On the basis of regression analyses using factor scores from the psychological variables as predictors, high scores on a psychopathology factor and low scores on a defensiveness factor predicted both bulimia and dieting. Low self-concept scores also predicted bulimia. These data indicate that both continuity and discontinuity characterize the relation between dieting and bulimia.     

Does Familism Lead to Increased Parental Monitoring?: Protective factors for Coping with Risky Behaviors

We examined coping with risky behaviors (cigarettes, alcohol/drugs, yelling/ hitting, and anger), familism (family proximity and parental closeness) and parental monitoring (knowledge and discipline) in a sample of 56 adolescents (11–15 years old) predominantly of Mexican descent at two time points. Multiple linear regression analysis indicated that more time spent with family (proximity) at Time 1 significantly predicts higher parental monitoring at Time two. Coping with more risky behaviors at Time 1 was significantly associated with less parental monitoring at Time 2. More parental closeness Time 1, more parental monitoring Time 1, and more parental monitoring Time 2 were associated with less coping with risky behaviors at Time 2. The cultural value of familism, particularly spending time with family in positive activities, appears to increase parental monitoring which may lead to less coping with risky behaviors among Mexican descent adolescents. Future studies may investigate gendered mechanisms for how extended family may increase not only parental knowledge of youth activities, but also youth perception of supervision.     

Dieting behavior in Norwegian adolescents

In a sample of Norwegian adolescents (n = 1117) 27, 4% of the girls and 9% of the boys reported that they were dieting. Using multiple regression analyses, we were able to predict 50% of girls dieting behavior and 24% of boys dieting behavior. Psychological concerns relating to weight and eating (WEC) as well as perceptions of feeling fatter than others were the only significant predictors of dieting in girls, whilst dieting in boys could also be predicted by their Body Mass Index. Dieting girls who scored high on the Weight and Eating Concerns Inventory were found to suffer constipation and binge eating attacks more often than other dieting girls. This was taken as an indication that these girls were at risk of developing an eating disorder.     

Distractibility in dieters and nondieters: an alternative view of "externality"

Two experiments were performed in an investigation of the effects of distraction and emotional arousal on the proofreading performance of dieting female subjects. In Experiment 1, it was found that distraction initially impaired the performance of dieters and facilitated the performance of nondieters, a pattern previously shown by Rodin to apply to obese and normal weight subjects, respectively, and interpreted as evidence of greater externality in the obese. Subsequent retesting of the same subjects in succeeding months, however, revealed a complete reversal of the original results. In Experiment 2, the reaction to distraction found in the first phase of Experiment 1 was obtained when subjects were in a situation of minimal threat. In a situation of high threat, the relative distractibility of dieters was reversed, as in the latter phases of Experiment 1. An explanation is offered for these data in terms of the greater emotionality of dieters, the susceptibility of cognitive performance to arousal (distraction, anxiety) manipulations, and the potentially competing effects of distraction and anxiety. Implications for the prevailing "trait" view of externality (stimulus binding) are discussed.     

Parental Psychological Control and Adolescent Problem Behaviors: The Role of Depressive Symptoms

Parental psychological control has consistently been linked to greater engagement in problem behaviors among adolescents, including over-eating behaviors, under-eating behaviors, risky cyber behaviors, and substance use. Previous research has suggested that child characteristics, such as temperament, may moderate this association. However, little research has examined characteristics of the adolescent that may place them at greater risk for experiencing such problem behaviors as a result of psychologically controlling parenting. Therefore, the current study examined the role of adolescents’ depressive symptoms as a risk factor (moderator) for the association between parental psychological control and adolescent problem behaviors. Participants included 161 adolescents (M_age?=?14.42, SD?=?1.73; 80.7% Caucasian; 59.6% female) living in a University city in a Mid-Atlantic state. Participants completed survey questionnaires about parental psychological control, problematic eating behaviors, risky cyber behaviors, substance use, and depressive symptoms. Results indicated that psychological control was significantly and positively associated with under-eating behaviors. Psychological control was also found to be associated positively with risky cyber behaviors and substance use, but only for adolescents who reported greater depressive symptoms. The findings provide support for the role of depressive symptoms as a risk factor for the associations between psychological control and problem behaviors among adolescents.     

Changing the body image concern and eating behaviour of chronic dieters: The effects of a psychoeducational intervention

Abstract

A program designed to diminish body image concern and to normalise the eating of chronic dieters was evaluated experimentally and by monitoring outcomes for 12 months. The subjects were 82 females (mean age 44.4 years, mean BMI 31.4). Data from repeated measures of eating style, self-esteem and body shape concern revealed a strong, positive and enduring intervention effect. At 12 months the majority (86%) of the subjects were not dieting and 73% reported “sometimes” or “often” engaging in natural eating, i.e., unrestrained and physiologically cued eating. A positive relationship was found between extent of natural eating and the likelihood of weight loss or weight maintenance. It is concluded that female dieters can derive considerable benefits from programs promoting natural eating.     

A diathesis-stress model of engagement in risky behaviors in Chinese adolescents

The current study examined whether the association between the occurrence of negative events and increased engagement in risky behavior is moderated by maladaptive and/or adaptive coping strategies. At time 1, 411 adolescents (ages 14–19) from Yue Yang, Hunan, completed self-report measures assessing coping strategies, engagement in risky behaviors, and the occurrence of negative events. Once a month for the subsequent 6 months, adolescents completed measures assessing engagement in risky behaviors and the occurrence of negative events. In line with our hypotheses, results of hierarchical linear modeling analyses indicated that adolescents possessing high levels of maladaptive coping strategies reported greater engagement in risky behaviors following the occurrence of negative events than adolescents possessing low levels. In contrast to our hypotheses, the association between the occurrence of negative events and increased engagement in risky behavior was not moderated by adaptive coping strategies.     

Associations between Race and Eating Disorder Symptom Trajectories in Black and White Girls

Epidemiological research suggests racial differences in the presentation of eating disorder symptoms. However, no studies have examined associations between race and eating disorder symptom trajectories across youth and adolescence, which is necessary to inform culturally sensitive prevention programs. The purpose of the current study was to examine the trajectories of eating disorder symptoms from childhood to young adulthood and to examine whether race was associated with trajectory group membership. Data were drawn from 2,305 Black and White girls who participated in a community-based longitudinal cohort study (Pittsburgh Girls Study) examining the development of psychopathology. The child and adult versions of the Eating Attitudes Test assessed self-reported eating disorder symptoms at six time points between ages 9 and 21 years. Growth mixture modeling was used to examine developmental trajectories of dieting, bulimia/food preoccupation, and total eating disorder symptom scores. Given potential confounds with race and disordered eating, financial strain (i.e., receiving public assistance) and weight were included as covariates. Four to six distinct developmental patterns were found across eating disorder symptoms, including none, increasing, decreasing, or increasing-decreasing trajectories. Black girls had a greater likelihood of being in the decreasing trajectories for dieting, bulimia/food preoccupation, and total eating disorder symptom scores. White girls were more likely to follow increasing trajectories of dieting and total eating disorder symptom scores compared to Black girls. These results highlight the importance of examining the influence of racial background on eating disorder symptoms and the potential need for differences in the timing and focus of prevention interventions in these groups.     

Significance of overvaluation of shape and weight in an ethnically diverse sample of obese patients with binge-eating disorder in primary care settings

Undue influence of shape or weight on self-evaluation--referred to as overvaluation--is a core feature across eating disorders, but is not a diagnostic requirement for binge-eating disorder (BED). This study examined overvaluation of shape/weight in ethnically diverse obese patients with BED seeking treatment in primary care. Participants were a consecutive series of 142 (105 female and 37 male) participants with BED; 43% were Caucasian, 37% were African-American, 13% were Hispanic-American, and 7% were of "other" ethnicity. Participants categorized with overvaluation (N=97; 68%) versus without clinical overvaluation (N=45; 32%) did not differ significantly in ethnicity/race, age, gender, body mass index, or binge-eating frequency. The overvaluation group had significantly greater levels of eating disorder psychopathology, poorer psychological functioning (higher depression, lower self-esteem), and greater anxiety disorder co-morbidity than the group who did not overvalue their shape/weight. The greater eating disorder and psychological disturbance levels in the overvaluation group relative to the non-overvaluation group persisted after controlling for psychiatric co-morbidity. Our findings, based on an ethnically diverse series of patients seeking treatment in general primary care settings, are consistent with findings from specialist clinics and suggest that overvaluation does not simply reflect concerns commensurate with being obese or with frequency of binge-eating, but is strongly associated with heightened eating-related psychopathology and psychological distress. Overvaluation of shape/weight warrants consideration as a diagnostic specifier for BED as it provides important information about severity.     

Moving beyond the trait conceptualization of self-esteem: The prospective effect of impulsiveness, coping, and risky behavior engagement

Past research has largely focused on examining self-esteem as an independent as opposed to a dependent variable. At the same time, research suggests that during adolescence, self-esteem is subject to yearly, monthly, as well as daily change, and consequently, it is important to identify underlying vulnerability factors and behaviors, which shape self-esteem lability. In the current multi-wave, longitudinal study, 142 adolescents between the ages of 12-18 completed monthly assessments across 4 months. At the initial assessment, adolescents provided self-report data pertaining to impulsiveness, maladaptive coping, risky behavior engagement, and self-esteem. At each of the follow-up assessments, adolescents provided information about risky behavior engagement and self-esteem. Results of time-lagged, idiographic multilevel mediation analyzes indicated that risky behavior engagement mediated the relationship between impulsiveness/maladaptive coping and subsequent low self-esteem. Critically, when included in the same model, impulsiveness was significant above and beyond maladaptive coping. Additionally, the reverse model with self-esteem as the predictor and risky behavior included as the dependent variable was not significant suggesting that our effect was unidirectional. As a whole, these findings suggest that impulsive youth may engage in behaviors, which ultimately precipitate negative self-evaluations and transient declines in self-esteem.     

Angry rumination moderates the association between perceived ethnic discrimination and risky behaviors

Perceived ethnic discrimination (PED) is associated with increased engagement in risky behaviors in ethnic minority emerging adults. Risky behaviors may reflect efforts to cope with emotional distress like depression or anxiety resulting from PED, particularly for individuals with poor emotion regulation skills. We hypothesized that the association between PED and risky behaviors would be particularly strong for emerging adults with tendencies for angry rumination. We further hypothesized that increased depressive and anxious symptoms would mediate the effect of the PED-rumination interaction on risky behaviors. In this survey study, 155 ethnic minority college students completed measures of PED, depressive and anxiety symptoms, trait angry rumination, and risky behaviors. Analyses revealed that angry rumination moderated the association between PED and greater risky behaviors. Depressive and anxiety symptoms did not mediate this effect. Although cross-sectional, these findings suggest that individuals with poor coping skills may be especially likely to respond to stressors such as PED by engaging in risky behaviors. Implications include using rumination-focused interventions in order to prevent engagement in risky behaviors in ethnic minority emerging adults.     

Prevalence of Disordered Eating Behaviors and Bulimia Nervosa in a Sample of Mexican American Female College Students

Disordered eating behaviors and bulimia nervosa were examined in a sample of female Mexican Americans. Results showed that 1.4% to 4.3% could be classified with bulimia. Just over 11% indicated regular binge eating; dieting and exercising were the primary techniques used for weight control. Implications for intervention are briefly discussed.     

Self‐regulatory strength amplification through selective information processing

We propose and demonstrate that although depletion of self-regulatory strength is common, it is not inevitable. Four experiments show that under certain conditions, consumers can amplify their self-regulatory strength and, as a result, increase their ability to control their behavior. Experiments 1–3 examine the depleting effects of information processing by exposing dieters and nondieters to either cost or pleasure information about chocolate. The results of experiments 1–3 show that when dieters have the ability to monitor the costs of consumption, they are motivated to mobilize additional strength and increase their ability to self-regulate. In experiment 4 we show the practical implications of our work and show that dieters are better able to control their eating because they choose to focus more on the cost (versus pleasure) of consumption.     

Prevalence of bulimic behaviors and trends in eating attitudes among Turkish late adolescents

The eating attitudes and the prevalence of bulimic behaviors in a group of 300 late adolescents were investigated using the key questions from the Bulimia Investigatory Test, Edinburgh (BITE), and additional questions. Only four subjects (1.3%) scored above the cut-off point on the BITE, and prevalence rates of males and females were the same. Results showed that higher symptom scale scores were associated with the emergence of binge eating behavior and high energy intake. Females were less likely than males to see themselves as normal eaters and more likely to feel "miserable" when they binge. Higher score groups evidenced more dieting behavior than other groups and also more abnormal eating behavior. It was concluded that the prevalence of bulimic behaviors in Turkish late adolescents was low, but there was an increasing risk since they share Western ideals of slimness and engage in dieting.     

An experimental test of the effects of dieting on bulimic symptoms: the impact of eating episode frequency

Prospective studies suggest dieting increases bulimic symptoms, but experiments suggest that dieting decreases bulimic symptoms. One possible explanation for the conflicting findings is that real world dieting involves less healthy dieting techniques, such as meal skipping, than prescribed diets. We tested whether the manipulation of eating episode frequency during dieting impacted bulimic symptoms. We expected that people on a diet involving fewer eating episodes would exhibit greater increases in bulimic symptoms than people on a diet involving more frequent eating episodes or waitlist controls. Participants on both 6-week diets lost more weight than controls, confirming dieting was manipulated, and showed greater reductions in bulimic symptoms than controls; however, the dieting conditions did not differ on either outcome. Results provide further experimental evidence that dieting does not increase bulimic symptoms, but suggests that eating episode frequency has little impact on this outcome.
