There is no doubt that the search for organic products is already more than a trend; it is an indisputable reality. More and more people are opting for a healthier lifestyle that starts with food, which has awakened a growing interest in understanding the reasons for these purchases. The motivational attributes of consumers’ decisions regarding the consumption of organic products are the main aim of this study. The survey included 250 respondents that filled a questionnaire by email and by personal interviews. We used a non-probabilistic sampling method, namely convenience sampling and the best–worst scaling method to analyze 10 attributes of organic purchasing decisions. Then, we studied the impact of the classification variables age, gender, academic level, place of residence, children under 18 living at home, and place of purchase of organic products on the attributes. Applying a chi-square test, we only obtained statistically significant differences for children under 18 living at home and the certification warranty (p = 0.011). The results show the dominance of credence attributes and egoistic motivations on organic consumption and may indicate a path towards the standardization of the organic consumer profile. This study emphasized that we may be facing a new organic consumer, for whom health-related factors are not just significant but overwhelming as well.

Consumer interest in organic food has surged globally, driven by health, sustainability, and ethical considerations. Key factors include perceived safety, nutritional benefits, and environmental impact, while high prices and limited availability remain barriers. This study examines the factors influencing organic food preferences among Greek consumers, focusing on attribute importance, demographic variations, purchasing locations, and regional differences. A sample of 250 consumers was analysed using a best-worst scaling methodology to research the importance of organic food attributes. The two main attributes were then further analysed using ordinal regression models. Health benefits, particularly the absence of chemicals, emerged as the most valued attribute, followed by nutritional value, absence of GMOs, better taste expectations, and environmental impact. Certification showed intermediary importance, and price, country of origin, availability, and natural appearance were found to have lower importance. Women and highly educated individuals show greater recognition of organic food’s health and nutritional advantages. Consumers in rural regions exhibited stronger preferences for organic products, influenced by cultural traditions, trust in local sourcing, and economic accessibility, while urban consumers displayed more scepticism. For the Greek participants included in the study, supermarkets dominate organic food sales due to affordability and convenience.

The consumption of organic products has consistently increased over the last decades, covering increasingly diversified consumers, both in the characteristics and the reasons associated with consumption. This heterogeneity evidences the need to examine in depth the reasons for the purchase and consumption of these products. The core aim of this study is related to the motivational drivers of organic consumption. The survey included 250 respondents from Andalusia (Spain) who completed an online questionnaire and personal interviews. A convenience sampling method was applied, and the best-worst scaling method allowed us to analyze ten attributes of organic purchasing behavior. Health benefits and environmental impact are the key attributes explaining the consumption of organic products. To deeply understand organic consumer motivations, we studied the influence of six classification variables over the studied attributes. Applying ordinal regressions, we found that having children under 18 at home and a consumer’s academic level contribute in a relevant way to explain the valorization of the health benefits attribute. Also, the place to purchase organic food and academic level correlates with the valuation of GMOs in food. Andalusia is one of the largest European regions for organic production but with minor relevance in consumption. Nevertheless, despite this apparent paradox, the results of the present study point to a consumer profile very similar to other European countries with consolidated organic consumption.

O Projeto de investigação AgeNortC resulta da parceria entre Institutos e Escolas Politécnicas que ministram formação em Gerontologia e as Autarquias dos respetivos territórios (Viana do Castelo, Bragança e Coimbra) e visa avaliar o impacto da participação em atividades promovidas pelas autarquias no envelhecimento bem-sucedido. Neste artigo apresentam-se os resultados de Viana do Castelo relativos ao bem-estar psicológico, avaliado pelas Escalas de Bem-estar Psicológico de Ryff. Recolheu-se informação numa amostra de 52 participantes, com idades dos 55 aos 84 anos e que frequentam iniciativas promovidas pelas autarquias, os quais foram emparelhados segundo género e idade com pessoas que não frequentam essas iniciativas. Conclui-se que, a partir dos 75 anos de idade, a participação em atividades dos projetos públicos de intervenção comunitária resulta em ganhos significativos no bem-estar psicológico, nomeadamente nas dimensões crescimento pessoal e propósito na vida.

Consumer demand for organic products has grown substantially in Southern Europe, driven by health, environmental, and ethical concerns. Understanding cross-country differences in attribute preferences and sociodemographic influences is critical to inform marketing strategies and policy interventions targeting organic food consumption. To perform a comparative study across Portugal, Spain, and Greece, regular organic consumers were surveyed (250 per country) using a culturally adapted Best–Worst Scaling questionnaire. Socio-demographic variables and ten organic food attributes were analysed using MANOVA, Kruskal–Wallis tests, PCA, and cluster analysis. Spanish and Portuguese consumers prioritised health, environmental impact, absence of GMOs, and certification, while Greeks emphasised price, appearance, taste expectation, and nutrition. Age, gender, and education influenced attribute importance differently across countries, revealing distinct national consumption patterns and preferences. Findings highlight substantial heterogeneity: health and environmental attributes dominate in Portugal and Spain, reflecting strong certification and sustainability awareness, whereas Greek consumers focus on value, sensory qualities, and nutrition, indicating lower organic uptake and stronger price sensitivity. Older and more educated consumers valued certification and provenance, women emphasised health and environmental benefits, and men responded more to convenience and status cues. These patterns suggest that marketing and policy strategies should combine universal motivators with tailored approaches addressing national, demographic, and cultural differences to enhance organic consumption. Cross-country differences reveal the need for context-specific interventions promoting organic food while leveraging common health and sustainability drivers.
