Study of the Relationship between Food Addiction and Food Craving with Body Mass Index
Leila Khabir, Golsa Karambakhsh, Nurallah Mohammadi,
Volume 1, Issue 3 (9-2017)
Abstract
Background: There is growing interest and debate about whether an addictive process contributes to problematic eating outcomes, such as obesity. Craving is a core component of addiction. Food craving is a state in which people consume foods that are craved. Food craving is a strong driving force for obesity and overweight. This study aimed to examine the relationship between food addiction and food craving with body mass index. Methods: This study was correlational. The community sample for this research was female students of Shiraz University. Data were obtained from 60 female students of Shiraz University and a sampling method was available. Instruments included the Yale Food Addiction Scale (YFAS), Food Cravings Questionnaire (FCQ), and Body Mass Index (BMI). Data were analyzed by SPSS version 22. Results: Regression analyses confirmed the hypothesis that food addiction (F=17, ρ <0.0001) and food craving (F=14, ρ <0.0001) predicted body mass index. 25 percent of body mass index changes are related to food addiction and 18 percent to food craving. Conclusion: The current results highlight the importance of further evaluating the role of an addictive process in problematic eating behaviors and obesity and also potentially targeting food cravings in intervention approaches.
 

The Evaluation of Psychometric Properties of Weight Bias Internalization Scale (WBIS)
Leila Khabir, Kosar Taghizadeh,
Volume 17, Issue 21 (8-2023)
Abstract
Background & Aims: The present research aimed to evaluation of psychometric properties of Weight Bias Internalization Scale (WBIS) and comparison of Internalization of weight bias in women with overweight and normal weight.
Materials & Methods: Sample was 200 female (100 with normal weight and 100 with overweight) selected using random sampling among female referring to Shiraz’s sport clubs. The participants in this research responded to WBIS and Body Image Concern Index (BICI) and their BMI index were calculated.
Results: The coefficients of the internal similarity method and the correlation of the two halves of Spearman-Brown and Guttman were estimated as 0.84, 0.72 & 0.70, respectively. Also, the validity of the questionnaire was checked by confirmatory factor analysis and correlation with the body image concern questionnaire. Confirmatory factor analysis showed that the data of this research has a good fit with the single-factor model of Internalization weight bias scale. The correlation of Internalization weight bias scale with body image concern questionnaire, appearance dissatisfaction factor and social performance interference factor were 0.57, 0.59 and 0.59 respectively. Also, the two groups with normal weight and overweight had a significant difference in terms of Internalization weight bias variable (ρ<0.003, t=4.42).
Conclusion: This research showed that the Persian form of weight bias internalization scale has good reliability and validity and this tool can be used in clinical and research situations to evaluate weight bias internalization.

The Validation of of Trait Self-Objectification Questionnaire (TSOQ)
Leila Khabir, Kowsar Taghizadeh,
Volume 19, Issue 23 (2-2024)
Abstract
The present research aimed to evaluation of Looking at the shape of women's body as a commodity and sexual object has caused abnormal behavior in women, and one of the consequences of this approach is that girls and women consider themselves objects. Therefore, the aim of this study was to investigate the psychometric properties of Trait Self-Objectification Questionnaire (TSOQ). There for, 200 females with age 18 and more selected using random sampling among female referring to sport clubs in shiraz, responded to TSOQ and Body Image Concern (BICI). The reliability of the TSOQ were calculated in internal consistency methods, spearman-brown and guttman spilt-half correlation investigated that coefficients were 0.81, 0.82 & 0.82 for observable appearance-based factor and 0.85, 0.84 & 0.86. The validity of the inventory was investigated by confirmatory factor analysis and concurrent validity with BICI. In confirmatory factor analysis, Goodness Fit Indexes showed that two factorial models had good fit. Concurrent validity showed whole score of TSOQ was correlated with whole score of BICI (r=0.40), dissatisfaction of the body (r=0.42) and interference of social function (r=0.39) too. In general, findings of the research confirm appropriate validity and reliability of the Persian form of Trait Self-Objectification Questionnaire showed that we can simply apply this instrument in clinical and research situation for assessment of self-objectification.
