This study aimed to compare the change in consumer behaviour in the face of high inflation with respect to food security in the Turkish population by developing a 3-factor The Impact of Food Inflation on Consumer Behaviour (IFI-ConB) scale. Item generation and expert evaluation, item purification by preliminary application, and final administration were conducted. The moderate to severe food insecure individuals exhibited a higher inflation impact score on food consumption patterns, food shopping behaviours, and food purchasing motives factors compared to secure to mild insecure individuals. A positive correlation was found between the inflation impact score by IFI-ConB and the price motive for food choice. The primary food choice motive was health among the secure to mild insecure individuals, while for the moderate to severe food insecure individuals, it was price. The findings indicate that food insecure individuals are more affected by high food inflation compared to food secure individuals.

Objectives: The single-item Food Choice Questionnaire (FCQ) is a self-reported instrument with 11 dimensions to assess food choice motives alternative to the multi-item FCQ. This study aimed to examine the validity and reliability of a Turkish version of the questionnaire. Materials and Methods: In phase 1, forward-backwards translation, cognitive debriefing with thirty participants, and content validity with ten experts were carried out. In phase 2, the psychometric properties were evaluated through a cross-sectional survey. A total of 350 responses were analyzed for convergent validity by comparing dimensions of single-item and multi-item FCQs. The questionnaire was reposted after a month, and 50 re-administration data (11.4% retest rate) were examined for test-retest reliability. Results: The eight dimensions of single-item FCQ (health, mood, convenience, sensory, price, weight, and familiar) were correlated with corresponding factors in multi-item FCQ, ranged between 0.431 to 0.646. The three dimensions (environment friendliness, animal friendliness, and social justice) corresponding to a single factor regarding ethical concern in multi-item FCQ were analyzed separately and significantly correlated (0.569, 0.433, and 0.572 respectively). All correlations were statistically significant at p <0.001 significance level. The Pearson’s correlations of test-retest analysis ranged from r = 0.407 to 0.673 (p = 0.000). The intraclass correlation coefficient values ranged between 0.581 to 0.796, indicating moderate to good reliability for all dimensions. The sensory appeal, convenience, and price dimensions were the most crucial motives. Conclusion: The results indicate that the single-item FCQ is a valid alternative instrument in the Turkish population.

Food insecurity, as a reflection of both material deprivation and the broader social and psychological challenges related to accessing food, has emerged as a core indicator of sustainable development. This cross-sectional study examines the link between food security status and multidimensional well-being in Türkiye, a country facing high inflation and income inequality. An online survey was conducted in December 2024, involving 526 participants. Food security was assessed by the Food Insecurity Experience Scale, and the Flourish Index was used to assess multidimensional well-being across five domains. Perceptions of inflation and income inequality were assessed using single-item questions, alongside sociodemographic information. Food insecurity was significantly associated with the perceived inflation impact (d = − 0.37, p = .009) and income inequality (d = − 0.23, p < .001). The moderately or severely food insecure group reported a lower Flourish Index (d = 0.56, p < .001), particularly in life satisfaction (d = 0.53, p < .001) compared to food secure or mildly food insecure group. Hierarchical linear regression analysis identified monthly income status and influence of religious belief as significant positive predictors of the Flourish Index (p < .001), while food insecurity showed a significant negative association even after adjusting for these factors (β = − 0.16, p < .001). Cluster analysis revealed four distinct profiles based on food security, income status, and religious influence. Significant differences were observed in the Flourish Index and all its domains across the clusters (p < .001). The largest effect sizes were found in life satisfaction (η² = 0.17), happiness (η² = 0.137), and the overall Flourish Index score (η² = 0.127) indicating variation in well-being. Participants in the “Financially Fragile & Low Religious” group reported the lowest scores across most domains, whereas those in the “Financially Secure & Highly Religious” group exhibited the highest levels of flourishing. Food insecurity was associated with reduced flourishing across multiple domains under economic uncertainty, and well-being outcomes differed across groups defined by financial conditions and religious engagement. This suggests that policy and intervention strategies targeting food insecurity should adopt a multidimensional perspective on well-being.

Sürdürülebilirlik küresel kalkınmada temel strateji olup bu doğrultuda besin sistemlerinin dönüşümü gerekmektedir. Besin sistemi sadece besinin nasıl elde edildiğini değil, besinin ilişkili olduğu tüm süreçlerin ve unsurların yanı sıra ortaya çıkardığı sonuçları da kapsamakta olup sürdürülebilirliği hedeflenmektedir. Besin sistemlerinin sürdürülebilir olması; ekonomik, sosyal ve çevresel temellere dayanması ve herkese besin güvencesi imkânı sağlayabilmesine bağlıdır. Mevcut besin sisteminde gizli maliyetlerin dikkate alınmaması besin sistemlerinin sürdürülebilirliğini etkilemektedir. Besinin piyasa değerine yansıtılmayan bu maliyetler dışsallaştırmaları ifade etmektedir. Çevresel, sağlık, sosyal ve ekonomik olarak kategorize edilebilen bu dışsallaştırmalar negatif de olsa pozitif de olsa sonuçta bir kesimin tercihleri ve bunların sonuçları başkalarını hatta sonraki nesilleri etkilemektedir. Besinin gerçek maliyeti yaklaşımı, dışsallaştırmalardan gelen gizli maliyetlerin değerlendirilerek pazar değerine yansıtılmasını sonuçta besinin gerçek fiyatını hedeflemektedir. Mevcut ekonomiler tüketicilerin besinleri gizli maliyetleri dâhil olmadan iki hatta üç kata kadar daha ucuz alabildiği fakat farkında olmadan başta vergilerle olmak üzere bu maliyetleri kendisinin ödediği düzene dayanmaktadır. Besinin fiyatı gerçek değerini yansıtmamakta olup toplumda farkındalığın oluşmasını engellemekte, sürdürülebilir olmayan, sağlıksız ve satın alınabilirliği düşük besinlerin üretimini teşvik etmektedir. Fakat hem gerçek maliyet muhasebesinde dışsallaştırmaların değerlendirilmesinde problemler hem de bu maliyetle belirlenecek besinin gerçek fiyatının tüketici ve üretici açısından potansiyel riskleri mevcuttur. Bu derlemede sürdürülebilir kalkınmada beslenme ve besin sistemlerinin rolüyle beraber besin sisteminin dönüşümünde besinin gerçek maliyeti ve fiyatı teorilerinin açıklanması amaçlanmaktadır.

Aims: Trust plays a critical role in the decision‐making and responsible use of artificial intelligence within professional contexts in health science. This study aimed to develop and validate a novel scale to assess dietitians' perceived trust in dialogue‐based artificial intelligence systems within professional practice. Methods: A three‐phase approach was employed to develop and validate the Dietitians’ Perceived Trust in Artificial Intelligence for Professional Practice Scale. Phase I involved generating 53 items from a literature review, which were reduced to 33 items by 10 experts via the Davis technique. In Phase II, exploratory factor analysis was conducted on data from 92 participants, resulting in a 12‐item, four‐factor structure: Data Security, Professional Competence, Scientific Accuracy, and Usability. In Phase III, the psychometric properties were evaluated, and its relationship with the Artificial Intelligence Literacy Scale was examined in a sample of 190 dietitians. Results: Confirmatory factor analysis confirmed model fit with all standardised loadings ranging from 0.69 to 0.89. Internal consistency was high (Cronbach's alpha = 0.89), and reliability values ranged from 0.84 to 0.94 across the factors. Test–retest reliability was supported by intraclass correlation coefficients ranging from 0.66 to 0.86. A significant correlation was observed between the total scores of the Dietitians’ Perceived Trust in Artificial Intelligence for Professional Practice Scale and the Artificial Intelligence Literacy Scale ( r _s = 0.256, p < 0.001). Conclusions: The Dietitians’ Perceived Trust in Artificial Intelligence for Professional Practice Scale is a valid and reliable instrument capturing multidimensional aspects of trust in artificial intelligence tools among dietitians.
