RESUMEN
Background and Purpose: This study evaluated the validity and reliability of the Persian version of Positive Body Image among Adolescents Scale (PBIAS-P) in Tehran, Iran, in order to better understand adolescents' positive perceptions of their physical selves and the accompanying thoughts and emotions. Methods: This cross-sectional study was carried out involving adolescents from Tehran Province, Iran, in 2022. Both exploratory factor analysis and confirmatory factor analysis were performed in order to evaluate the construct validity of the PBIAS-P. Cronbach's alpha, McDonald's omega, and intraclass correlation coefficients were also used to confirm the internal consistency of the scale. Results: The findings indicate that three factors extracted from the PBIAS-P account for 50.1% of the total variance. The model fit is considered good based on cut points for various fit indices. All factors had values of Cronbach's alpha, McDonald's omega, and average interitem correlation above .73, .74 and .4, respectively. Also, test-retest reliability for three factors was acceptable. Conclusions: The PBIAS-P has acceptable validity and reliability in Iranian adolescents, making it useful for researchers, psychologists, and health care professionals.
RESUMEN
Background and aim: The correlation between eating attitudes, positive body image, and body esteem is a pivotal area of research that has garnered substantial attention in recent years, given its implications for both mental and physical well-being. The objective of this study was to examine the interplay between positive body image, body esteem, and eating attitudes within an Iranian population. Materials and methods: This study employed a cross-sectional study design and was conducted in the year 2022. A convenience sample of 752 participants residing in Tehran, Iran, was included in the study. The data collection tools were comprised of a demographic registration form, the Adolescence/Adults Scale (PBIAS), the Eating Attitudes Test (EAT), and the Body Esteem Scale (BES) as measurement instruments. Results: Mean age of participants was 26.36 (SD = 8.49). Significant relationships were found among positive body image (B = - 0.095, ß = -0.150, p < 0.001), and body esteem (B = 0.175, ß = 0.149, p < 0.001) with eating attitudes. Conclusion: These findings suggest that individuals with positive body image and high body esteem may have healthier eating attitudes, while those with negative body image and low body esteem may be more likely to have unhealthy eating attitudes.
RESUMEN
Background: Several studies indicate a high prevalence of depression around the world during the period of the COVID-19 pandemic. Using a valid instrument to capture the depression of an individual in this situation is both important and timely. The present study aims to evaluate the psychometric properties of the Persian version of the Center for Epidemiological Studies Depression Scale (CES-D) among the public during the COVID-19 pandemic in Iran. Method: This is a cross-sectional study that was conducted in the Iranian population (n = 600) from April to July 2020. A two-part online form was used: sociodemographic characteristics and depression items (CES-D). The construct validity and internal consistency reliability of the scale were evaluated. Result: The results of the exploratory factor analysis illustrated two factors with 43.35% of the total variance of the depression were explained. Confirmatory factor analysis indicated that this model fits well. Internal consistency reliability was evaluated, and it was acceptable. Conclusion: The findings demonstrated that, in the Iranian sample, this depression scale yielded two factors (somatic and positive affects) solutions with suitable psychometric properties.
