THE RELATIONSHIP BETWEEN FEMININE GENDER ROLE STRESS, BODY IMAGE, AND EATING DISORDERS

The Feminine Gender Role Stress (FGRS) scale was used in two studies to determine whether eating disorders could be linked to the cognitive tendency among women to appraise specific situations as highly stressful because of rigid adherence to the traditional feminine gender role. Study 1 showed the FGRS scale could distinguish eating disorders from other psychiatric disorders in an inpatient setting and from normal college women. This suggests that women who have eating disorders report higher than usual levels of stress as a result of rigid adherence to the traditional feminine gender role. Study 2 looked at cardiovascular reactivity to a “feminine” (i.e., body image threat) and a control stressor and determined the FGRS scale could predict which women are threatened by feminine stressors. Results from these studies suggest feminine gender role stress may be the missing link between cultural values of femininity and vulnerability for eating disorders.

Evaluation of a cognitive–behavioral therapy intervention to improve body image and decrease dieting in college women

This two-group experimental study evaluated the effectiveness of a cognitive-behavioral body image intervention, adapted from an effective clinical intervention, with normal college females. Participants included nonclinical, freshman college women who were assigned randomly to either the experimental intervention or the control group (brief educational session). Participants were assessed prior to the intervention and again 1 month later on dieting behavior, body image, fear of fat, and anxiety concerning physical appearance. Although it was hypothesized that each of these variables would be lower in the experimental group, none of these results, except for a trend for decreased dieting, were found. Overall these results of slightly reduced dieting behavior are consistent with other research targeting primary and secondary prevention. This interventions failure to impact body image and eating behaviors of college students illustrates the continuing challenge of eating disorders prevention.

Development and preliminary validation of the cognitive behavioral dieting scale.

OBJECTIVE The purpose of this research was to empirically develop the Cognitive Behavioral Dieting Scale (CBDS), a measure of current dieting. METHOD The first study involved item generation and a procedure to boost internal consistency while reducing scale length. Study 2 involved a factor analysis and measures of scale reliability. The third study evaluated the ability of the CBDS to predict calorie intake and negative calorie balance from a 24-hr diet recall. Study 4 evaluated construct validity by comparing the CBDS to dietary restraint, body image, and health behavior self-efficacy. RESULTS The CBDS is a 14-item scale which measures current dieting behavior and related thoughts within the past 2 weeks. Internal consistency was alpha = .95 and 2-day test-retest reliability was r = .95. This scale provides a method for operationalizing dieting, provides a construct that is different from restraint, and assess dieting behavior on a continuum. Additionally, this scale was able to predict calorie intake and negative calorie balance above and beyond the predictive ability of physical variables (i.e., body mass index BMI] and exercise calories). An additional study of construct validity showed the CBDS was related to poor body image esteem and dietary restraint, but minimally related to healthy eating self-efficacy. DISCUSSION In conclusion, the CBDS shows promise as a valid and reliable measure of dieting behavior. This scale should have utility in future research on how current dieting relates to eating disorders, dietary restraint, and obesity.

A Writing Intervention for Negative Body Image: Pennebaker Fails to Surpass the Placebo

Abstract Pennebakers therapeutic writing paradigm was assessed as a brief intervention for negative body image. Females were randomly assigned to write about their body image (experimental; n = 23) or their bedroom (controls; n = 25) for four days. Body image, eating-disordered behavior, and mood were assessed at baseline, after the 4th day of writing, and at 1-month follow-up. Despite hypotheses that experimental participants would show more improvement over time, participation in the study, regardless of condition, was related to significant improvements in body image and mood, and decreased eating-disordered behavior over time. Placebo, sensitization effects, and regression to the mean are discussed as potential explanations for this unexpected finding. Suggestions for future research are made.

Empowerment, feminism, and self-efficacy: Relationships to body image and disordered eating

Sociocultural norms pertaining to an ideal of thinness for women likely play a role in the development and maintenance of disturbance in body image, and by extension, disordered eating. However, competing norms associated with feminism may buffer women from pressures associated with achieving the thin ideal. The present study explored the relationship between feminist ideology, empowerment, and self-efficacy relative to body image and eating behavior with a sample of U.S. undergraduate women (N=318) attending a southeastern U.S. mid-sized university. In planned hierarchical multiple regression analyses, endorsement of feminist ideology predicted perceptions of positive body image, but did not appear to predict disordered eating. Self-efficacy emerged as a robust predictor of positive body image and lower disordered eating even after controlling for perceptions of personal empowerment and feminism. Results, although limited by correlational data, suggest that self-efficacy may protect college-aged women from disordered eating and negative body image.

Measuring Adult Picky Eating: The Development of a Multidimensional Self-Report Instrument.

A brief multidimensional measure of adult picky eating (PE) behavior was developed using a large U.S. adult sample. In addition, the study explored associations between specific aspects of adult PE behavior and psychosocial impairment in effort to support the inclusion of adults in the Diagnostic and Statistical Manual for Mental Disorders-Fifth Edition (DSM–5) avoidant-restrictive food intake disorder (ARFID). The study included 3 phases of qualitative and quantitative data collection. Participants were 1,663 U.S. adults who completed online surveys. Exploratory and confirmatory factor analyses were used to develop PE subscales. Associations among the PE subscales and measures of psychosocial impairment were examined. Exploratory and confirmatory factor analysis supported a 16-item 4-factor model of adult PE that included subscales of meal presentation, food variety, meal disengagement, and taste aversion. The measure also demonstrated convergence with previous measures of PE. The meal disengagement and meal presentation subscales demonstrated significant associations with social eating anxiety, anxiety sensitivity, eating related quality of life (QOL), and psychological flexibility. Meal disengagement alone was significantly associated with depressive symptoms. The Adult Picky Eating Questionnaire (APEQ) demonstrated sound psychometric properties and may be used to further investigate adult PE behavior. The relationships between adult PE and psychological impairment, particularly social anxiety, support the inclusion of ARFID in the DSM–5.

Recollections of pressure to eat during childhood, but not picky eating, predict young adult eating behavior

Picky eating is a childhood behavior that vexes many parents and is a symptom in the newer diagnosis of Avoidant/Restrictive Food Intake Disorder (ARFID) in adults. Pressure to eat, a parental controlling feeding practice aimed at encouraging a child to eat more, is associated with picky eating and a number of other childhood eating concerns. Low intuitive eating, an insensitivity to internal hunger and satiety cues, is also associated with a number of problem eating behaviors in adulthood. Whether picky eating and pressure to eat are predictive of young adult eating behavior is relatively unstudied. Current adult intuitive eating and disordered eating behaviors were self-reported by 170 college students, along with childhood picky eating and pressure through retrospective self- and parent reports. Hierarchical regression analyses revealed that childhood parental pressure to eat, but not picky eating, predicted intuitive eating and disordered eating symptoms in college students. These findings suggest that parental pressure in childhood is associated with problematic eating patterns in young adulthood. Additional research is needed to understand the extent to which parental pressure is a reaction to or perhaps compounds the development of problematic eating behavior.

Predicting Ideal Body Mass Index: What Does Clothing Size Have To Do With It?

This study examined demographic and anthropometric variables as predictors of ideal body mass index (BMI) from cross-sectional, archival, self-reported data from the Psychology of Size Survey of 4014 U.S. residents collected in 2007. As hypothesized, ideal BMI can be predicted by a within gender hierarchical multiple regression analysis with the predictor variables of age, number of clothing sizes from ideal size, and current BMI; these variables account for 54.1% of variance in womens ideal BMI and 65.5% of variance in mens ideal BMI. Findings also demonstrated a logarithmic relationship between current BMI and ideal BMI, with increasing variance in ideal BMI for individuals with high current BMIs. These findings evidence the strong role of current body characteristics in the formation of ideals. Understanding how individuals conceptualize body ideals can inform researchers and practitioners alike, as this evidence has important implications related to both medical and psychological health.

Motivational Interviewing for Smoking Cessation Among College Students

Motivational interviewing has shown some success as an intervention for college student cigarette smokers. We tested the efficacy and process of a two session motivational-interviewing-based smoking intervention compared to an assessment/information session. College student participants assigned to the motivational interviewing condition did not differ significantly from participants in the assessment/information condition on smoking outcome variables one month later. However, both groups reported significant decreases in self-reported smoking over time, suggesting that brief interventions for college student smoking can be efficacious. Consistent with theory, the motivational interviewing group reported a significant increase in self-efficacy over time and reported stronger perceptions of the therapeutic alliance after the first session compared to assessment/information participants.

Body size dissatisfaction and avoidance behavior: How gender, age, ethnicity, and relative clothing size predict what some won’t try

Sixty-eight percent of U.S. adults are overweight/obese, and this epidemic has physical, psychosocial, and behavioral consequences. An internet sample of adults (N=2997) perceiving themselves as larger than ideal in clothing size reported their body mass index (BMI), relative clothing size (RS; discrepancy between current and ideal size), and avoidance behaviors. Exploratory factor analysis of 10 avoidance items produced social avoidance and body display avoidance factors. A relative importance analysis revealed RS as a better predictor than BMI for avoidance. A hierarchical multivariate analysis of covariance found RS to predict both avoidance constructs. The relationship between RS and both avoidance constructs was stronger for women than men, and for younger as compared to older participants. Caucasians reported more body display avoidance than African Americans. This suggests that personal dissatisfaction with body size may deter involvement in varied life events and that women are especially avoidant of activities that entail displaying their bodies.
