The influence of the stigma of obesity on overweight individuals
International Journal of Obesity, 2004
OBJECTIVE: To investigate the internalization of anti-fat bias among overweight individuals across a variety of attitudes and stereotypes. DESIGN: Two studies were conducted using the Implicit Association Test (IAT), a performance-based measure of bias, to examine beliefs among overweight individuals about 'fat people' vs 'thin people'. Study two also contained explicit measures of attitudes about obese people. SUBJECTS: Study 1 participants were 68 overweight patients at a treatment research clinic (60 women, 8 men; mean Body Mass Index (BMI) of 37.173.9 kg/m 2). Study 2 involved 48 overweight participants (33 women, 15 men) with a BMI of 34.574.0 kg/ m 2. RESULTS: Participants exhibited significant anti-fat bias on the IAT across several attributes and stereotypes. They also endorsed the explicit belief that fat people are lazier than thin people. CONCLUSION: Unlike other minority group members, overweight individuals do not appear to hold more favorable attitudes toward ingroup members. This ingroup devaluation has implications for changing the stigma of obesity and for understanding the psychosocial and even medical impact of obesity on those affected.
The Stigma of Obesity: A Review and Update
Obesity, 2009
nature publishing group Reviews epidemiology Obese individuals are highly stigmatized and face multiple forms of prejudice and discrimination because of their weight (1,2). The prevalence of weight discrimination in the United States has increased by 66% over the past decade (3), and is comparable to rates of racial discrimination, especially among women (4). Weight bias translates into inequities in employment settings, health-care facilities, and educational institutions, often due to widespread negative stereotypes that overweight and obese persons are lazy, unmotivated, lacking in self-discipline, less competent, noncompliant, and sloppy (2,5-7). These stereotypes are prevalent and are rarely challenged in Western society, leaving overweight and obese persons vulnerable to social injustice, unfair treatment, and impaired quality of life as a result of substantial disadvantages and stigma. In 2001, Puhl and Brownell published the first comprehensive review of several decades of research documenting bias and stigma toward overweight and obese persons (2). This review summarized weight stigma in domains of employment, health care, and education, demonstrating the vulnerability of obese persons to many forms of unfair treatment. Despite evidence of weight bias in important areas of living, the authors noted many gaps in research regarding the nature and extent of weight stigma in various settings, the lack of science on emotional and physical health consequences of weight bias, and the paucity of interventions to reduce negative stigma. In recent years, attention to weight bias has increased, with a growing recognition of the pervasiveness of weight bias and stigma, and its potential harmful consequences for obese persons. The aim of this article is to provide an update of scientific evidence on weight bias toward overweight and obese adults through a systematic review of published literature since the 2001 article by Puhl and Brownell. This review expands upon previous findings of weight bias in major domains of living, documents new areas where weight bias has been studied, and highlights ongoing research questions that need to be addressed to advance this field of study. A systematic literature search of studies published between January 2000 and May 2008 was undertaken on computerized psychological,
Internalization of Weight Bias: Implications for Binge Eating and Emotional Well-being*
Obesity, 2007
Objective: This study examined the relationship between internalization of negative weight-based stereotypes and indices of eating behaviors and emotional well-being in a sample of overweight and obese women. Research Method and Procedures: The sample was comprised of 1013 women who belonged to a national, nonprofit weight loss organization. Participants completed an on-line battery of self-report questionnaires measuring frequency of weight stigmatization and coping responses to deal with bias and symptoms of depression and self-esteem, attitudes about weight and obesity, and binge eating behaviors. In addition, participants were asked to list the most common weight-based stereotypes and whether they believed them to be true or false. Results: Participants who believed that weight-based stereotypes were true reported more frequent binge eating and refusal to diet in response to stigma experiences compared with those who reported stereotypes to be false. The degree to which participants believed stereotypes to be true or false was not related to types or amount of stigma experiences reported, self-esteem, depression, or attitudes toward obese persons. In addition, engaging in weight loss strategies as a response to bias was not predicted by stereotype beliefs or by actual stigma experiences, regardless of the amount or types of stigma reported. Discussion: These findings suggest that obese individuals who internalize negative weight-based stereotypes may be particularly vulnerable to the negative impact of stigma on eating behaviors and also challenge the notion that stigma may motivate obese individuals to engage in efforts to lose weight. This study highlights a new area of research that warrants attention to better understand weight stigma and its potential consequences for health.
Weighing obesity stigma: the relative strength of different forms of bias
International journal of obesity (2005), 2008
To compare the strength of weight bias to other common biases, and to develop a psychometrically sound measure to assess and compare bias against different targets. A total of 368 university students (75.4% women, 47.6% white, mean age: 21.53 years, mean body mass index (BMI): 23.01 kg/m(2)). A measure was developed to assess bias against different targets. Three versions of the universal measure of bias (UMB) were developed and validated, each focusing on either 'fat,' 'gay' or 'Muslim' individuals. These were administered to participants, along with two established scales of bias against each target and a measure of socially desirable response style. The UMB demonstrated good internal consistency, appropriate item-total and inter-item correlations, and a clear factor structure suggesting components of Negative Judgment, Distance, Attraction and Equal Rights. Construct validity was indicated by strong correlations between established measures of bias and eac...

Current measures of internalized weight bias assess factors such as responsibility for weight status, mistreatment because of weight, etc. A potential complementary approach for assessing internalized weight bias is to examine the correspondence between individuals' ratings of obese people, normal weight people, and themselves on personality traits. This investigation examined the relationships among different measures of internalized weight bias, as well as the association between those measures and psychosocial maladjustment. Prior to the beginning of a weight loss intervention, 62 overweight/ obese adults completed measures of explicit and internalized weight bias as well as body image, binge eating, and depression. Discrepancies between participants' ratings of obese people in general and ratings of themselves on both positive and negative traits predicted unique variance in measures of maladjustment above a traditional assessment of internalized weight bias. This novel approach to measuring internalized weight bias provides information above and beyond traditional measures of internalized weight bias and begins to provide insights into social comparison processes involved in weight bias.
Understanding Self-directed Stigma: Development of the Weight Bias Internalization Scale
Obesity, 2008
The present study developed the Weight Bias Internalization Scale (WBIS), an 11-item measure assessing internalized weight bias among the overweight and obese. Methods and Procedures: An Internet sample was recruited through online community discussion groups and snowball sampling via e-mail. Women (n = 164) and men (n = 34) with a BMI >25 kg/m 2 completed the WBIS and the Antifat Attitudes Questionnaire (AAQ), as well as measures of self-esteem, body image, mood disturbance, drive for thinness, and binge eating. Results: Results indicate that the WBIS had high internal consistency (Cronbach's α = 0.90) and correlated significantly with antifat attitudes but was not a completely overlapping construct (r = 0.31). The scale showed strong partial correlations with self-esteem (r = -0.67), drive for thinness (r = 0.47), and body image concern (r = 0.75), controlling for BMI. Internalized weight bias was also significantly correlated with measures of mood and eating disturbance. Multiple regression analyses were conducted using WBIS scores, antifat attitudes, and BMI as predictor variables of body image, mood, self-esteem, and binge eating. WBIS scores were found to significantly predict scores on each of these measures. Discussion: The WBIS showed excellent psychometric properties and construct validity. The study highlights the importance of distinguishing antifat attitudes toward others from internalized weight bias, a construct that may be closely linked with psychopathology.
Prejudicial and Stereotypical Attitudes about the Issue of Obesity: An Action Project
Psychology, 2017
Scientific literature about stereotypical and prejudicial attitudes toward obese people indicates rejection toward the obese individuals and preferences toward thin and average ones, as well as a stereotypical profile that attributes to obese people traits such as weakness, laziness, and sickness, while to thin and average people characteristics as beauty, strength, health, and successfulness (Tiggemann & Anesbury, 2000; Carels & Musher-Eizenman, 2010). One of the most useful strategies for reducing the effects of negative prejudices and stereotypes toward the obesity and obese people is constituted by contact, achievable both in face to face and imagined setting. Purpose: analysis of the exposure effects to stimuli (training course about prejudice on obesity) functional to reduce negative attitudes toward obese people. Participants: 55 psychology university students at University of Catania, Sicily (Italy). Implicit and explicit measures: 1) Anti-fat Attitudes and Dislike of Fat People Scale; 2) Semantic Differential Technique for Fat and Thin People Representation and Physical Self; 3) Fat Stereotypes Questionnaire; 4) GNAT (Nosek & Banaji, 2001). All measures were used before and after the training course (for three months) about the "obesity issue". Results (before-after the training course): a) low levels of anti-fat prejudice and of dislike of fat people; b) absence of change of fat stereotypes; c) significant increase in fat and thin people positive representation, as well as in self-representation; d) significant effects of the training course only in relation to an increase of accuracy in the GNAT application. Future suggestions regarding to the effects of the direct and imagined contact with obese people functional to reduce negative attitudes toward these target were discussed.
