RESUMEN
BACKGROUND: The Modified Yale Food Addiction Scale 2.0 (mYFAS 2.0) was developed with the primary objective of evaluating food addiction (FA). The present study aimed to undertake the translation, pilot testing, and evaluation of the psychometric properties of the mYFAS 2.0 within the Persian-speaking population. METHODS: The transcultural adaptation of the mYFAS 2.0 to the Persian language was conducted. Data collection was carried out through an anonymous online questionnaire. Participants completed the Persian versions of the mYFAS 2.0, Binge Eating Scale (BES), Barratt Impulsivity Scale (BIS-11), and Connor-Davidson Resilience Scale (CD-RISC). The assessment encompassed the evaluation of internal consistency reliability, factor structure, as well as convergent and discriminant validity of the aforementioned questionnaires. RESULTS: Confirmatory factor analysis revealed that the single-factor model of the Persian translation of mYFAS 2.0 performed satisfactorily, with comparative fit index (CFI) and Tucker-Lewis index (TLI) values exceeding 0.95, standardized root mean square residual (SRMR) less than or equal to 0.09, and root mean square error of approximation (RMSEA) below 0.03. The internal consistency and composite reliability of the mYFAS 2.0 were favorable in the entire sample, as well as in both male and female groups, with alpha (α) values of 0.83, ordinal alpha (αord) of 0.93, and composite reliability (CR) of 0.86. Additionally, significant relationships were observed between the total score of BES (r = 0.59, p < 0.001), BIS-11 (r = - 0.16, p < 0.001), and CD-RISC (r = 0.22, p < 0.001) with mYFAS 2.0-diagnosed FA presence, severity, and symptom count. CONCLUSIONS: The Persian version of the mYFAS 2.0 exhibited satisfactory psychometric properties.
In this study, researchers developed a Persian version of the Modified Yale Food Addiction Scale 2.0 (mYFAS 2.0) to assess food addiction in Persian-speaking individuals. They translated and tested the scale's reliability and validity through an online survey with 9606 Persian speaking participants. The results showed that the Persian mYFAS 2.0 performed well, with a reliable single-factor model. The internal consistency and reliability were good across the entire sample and in both male and female groups. The relationships between mYFAS 2.0 and other scales measuring binge eating, impulsivity, and resilience were significant. The findings suggest that the Persian version of mYFAS 2.0 is a reliable tool for assessing food addiction in the Persian-speaking population. The study used statistical analyses like confirmatory factor analysis, indicating the scale's robustness. Overall, the psychometric properties of the Persian mYFAS 2.0 were satisfactory, providing a valuable instrument for researchers and healthcare professionals studying and addressing food addiction in this population. The study contributes to cross-cultural research and enhances our understanding of food addiction in diverse linguistic communities.
RESUMEN
Background: In this study, the purpose was to investigate the risk and protective factors affecting craving among patients with substance use disorders (SUDs) on buprenorphine, methadone, or opium maintenance treatment in Isfahan, Iran. Methods: In the current cross-section path analysis model, the statistical population was all SUD patients in Isfahan who were under treatment with Methadone or Buprenorphine in 2018. The study sample included 482 people who were on maintenance treatment in Isfahan who were selected by random sampling in two stages. The Franken, Hendriks, and Brink Opiate Craving Questionnaire (OCQ), Substance Related Beliefs Questionnaire (SRBQ), Cognitive Emotion Regulation Questionnaire (CERQ), Patient Health Questionnaire, Sixbey Family Resilience Assessment Scale (FRAS) and the Self-Resiliency Scale (SRS) were used to collect data. A path analysis method and PLS software were used to analyze the data. Results: The results showed that the direct impacts of self-resilience (ß=-0.147, p = 0.009) and uncompromising strategies (ß = 0.249, p = 0.0001) on depression are significant. Also, the direct effects of belief in drugs (ß = 0.518, p = 0.0001) and depression (ß = 0.219, p = 0.0001) on craving are significant. Conclusion: Substance-related beliefs play an essential role in craving both directly and indirectly. The results of the present study can be used to carry out educational and therapeutic interventions for drug SUD patients.
