A validation study of the Italian version of the Attitudes Toward Obese Persons (I-ATOP) questionnaire

A psychometric examination of the cognitive flexibility scale and its association with Orthorexia Nervosa

BACKGROUND

The Cognitive Flexibility Scale (CFS) is a 12-item self-report questionnaire designed to assess cognitive flexibility. Despite its widespread use, its psychometric properties have yet to be evaluated in the Italian context. Furthermore, while cognitive flexibility has emerged as a central correlate in Feeding and Eating Disorders, only a limited number of studies have investigated its association with Orthorexia Nervosa (ON), a clinical condition characterized by a pathological fixation with healthy eating. The present study aimed to fill these two knowledge gaps.

METHODS

A total of 803 participants (Mage = 33.89, SD = 9.44; 68.6% females) were enrolled in the investigation. The sample was randomly split into two subsamples: the first one for examining the psychometric properties of the CFS, and the second one for evaluating its association with ON symptoms. Participants completed self-report questionnaires assessing the constructs under investigation.

RESULTS

Confirmatory factor analysis revealed a global dimension of cognitive flexibility, alongside a method factor accounting for covariance arising by reverse-worded items. The CFS, which was factorially invariant across genders, yielded a reliable total score (ω = 0.834) and provided evidence of convergent and criterion-related validity. Importantly, structural equation modelling showed that cognitive flexibility was negatively associated with emotional distress resulting from violations of orthorexic dietary rules (β = -0.279, p < .001).

CONCLUSIONS

The CFS demonstrated to be a psychometrically robust instrument in the Italian context. Moreover, cognitive flexibility may be an important treatment target for mitigating the distress derived from ON symptoms, informing the development of future therapeutic approaches.

Body shaming and internalized weight bias as potential precursors of eating disorders in adolescents

Introduction

Body shaming (BS) is a growing phenomenon within the school context, especially among adolescents. Recently, it has been described as an unrepeated act in which a person expresses unsolicited, mostly negative comments about an individual's body. The targeted person perceives these comments as negative, offensive or body shame-inducing. Empirical evidence also suggests that body weight is the most common reason that youths are teased and bullied. Indeed, weight stigma, described as bias or discriminatory behaviors, attitudes, feelings, and thinking about individuals, because of their weight, can lead to weight-based discrimination and victimization. Preliminary evidence suggests that BS and weight stigma have negative effects on psychological health both in the short and long term. In the delicate stage of adolescence development and pubertal maturation, BS experiences can be highly prevalent and it can lead to adverse outcomes such as eating disorders (ED). However, prevalence data in the Italian context are still lacking.

Methods

The study aims to estimate weight-related BS perceived by different sources (i.e., peers and family members) and their associations with public and internalized weight bias, body mass index (BMI), body dissatisfaction, and ED symptoms. A sample of 919 high school students (Mage = 15.97, SD = 1.58; 57.1% boys) completed a battery of self-report questionnaires assessing these variables.

Results

One in four students reported experiences of weight-related BS by peers or family members. A total of 37% reported having at least one BS experience in a lifetime. Higher scores of ED symptoms, body dissatisfaction, and weight bias were reported by adolescents who experienced BS, especially females. Among overweight participants, results showed that internalized weight bias partially mediated the relationship between BS by family members and ED symptoms and fully mediated the relationship between BS by peers and ED symptoms, after controlling for age, sex and BMI.

Discussion

These findings, despite their cross-sectional nature, add an important contribution to the creation of quantitative empirical evidence on the phenomenon of BS. Its role in explaining eating disorders, both alone and with the mediation of internalized weight stigma has been first proved and needs to be confirmed by longitudinal results.

The relationship between internalized weight stigma and physical and mental health-related quality of life in a large sample of women: a structural equation modeling analysis

PURPOSE

Health-related quality of life (HRQOL) refers to an individual's perception of their physical and mental health status over time. Although emerging evidence has documented a negative association between weight stigma (i.e., negative weight-related attitudes and beliefs towards individuals with overweight or obesity) and mental HRQOL, its influence on physical HRQOL still needs to be fully clarified. This study aims to investigate the impact of internalized weight stigma on mental and physical HRQOL by employing a structural equation modeling (SEM) approach.

METHODS

The Short Form Health Survey 36 (SF-36) and the Weight Bias Internalization Scale (WBIS) were administered to a sample of 4450 women aged 18-71 (M_age = 33.91 years, SD = 9.56) who self-identified in a condition of overweight or obesity (M_BMI = 28.54 kg/m²; SD = 5.86). Confirmatory factor analysis (CFA) was conducted to assess the dimensionality of the scales before testing the proposed structural model.

RESULTS

After establishing the adequacy of the measurement model, SEM results revealed that internalized weight stigma was significantly and negatively associated with both mental (β = - 0.617; p < 0.001) and physical (β = - 0.355, p < 0.001) HRQOL.

CONCLUSION

These findings offer additional support to prior research by confirming the association between weight stigma and mental HRQOL. Moreover, this study contributes to the existing literature by strengthening and extending these associations to the physical HRQOL domain. Although this study is cross-sectional in nature, it benefits from a large sample of women and the use of SEM, which offers advantages over traditional multivariate techniques, e.g., by explicitly accounting for measurement error.

Reliable Knowledge about Obesity Risk, Rather Than Personality, Is Associated with Positive Beliefs towards Obese People: Investigating Attitudes and Beliefs about Obesity, and Validating the Polish Versions of ATOP, BAOP and ORK-10 Scales

Obesity has reached epidemic proportions. With the increase in the number of obese people, we have also witnessed a rise in the stigmatisation of this population. The aim of our study was to: (I) validate Polish versions of the attitude toward obese people (ATOP) scale, the beliefs about obese persons (BAOP) scale, and translate the obesity risk knowledge scale (ORK-10); (II) analyse the relationship between personality and the knowledge about obesity, as well as attitudes and beliefs towards obese people.

METHODS

The translation procedure was based on the principles of intercultural validation scales. The study was conducted on a group of 306 individuals, including 189 females and 117 males.

RESULTS

The original three-factor structure of the ATOP scale was confirmed in the Polish version. Factor analysis confirmed the one-factor structure of the BAOP scale in the Polish version. A very strong correlation was found between ATOP/BAOP and ORK-10. The correlation of personality with ATOP/BAOP scales was at a low level. Regression analysis indicated that knowledge of obesity risk predicted ATOP and BAOP by more than 58% and 50%, in turn, personality only 20% and 3.7%, respectively.

CONCLUSION

The polish versions of ATOP, BAOP and ORK-10 scales are fully useful measurement tools. The knowledge about obesity risk is associated with beliefs and attitudes about obese people.
