- Coffee in capsules consumers' behaviour: a quantitative study on attributes, consequences and valuesPublication . de Oliveira, Alessandro Silva; Souki, Gustavo; Gandia, Rodrigo Marcal; Boas, Luiz Henrique de Barros VilasPurpose Coffee in capsules consumers' behaviour depends not only on the products' attributes, but also the consequences perceived by them and the alignment with their values. This paper aims to investigate the impacts of the Attributes of coffees in capsules on the consequences perceived by consumers concerning their consumption and the effects of these Consequences on consumers' Values. Design/methodology/approach This study developed a scale for assessing the perception of consumers of coffee in capsules about Attributes, Consequences and Values (A-C-V) regarding its consumption. A link to this survey's electronic questionnaire was posted on the social networks Facebook and Peabirus. This research sample is for convenience and accessibility and has 213 consumers of coffee in capsules. Structural Equation Modelling (SEM) was the statistical method used for data analysis. Findings Attributes have two sub-dimensions (Own attributes and Functional attributes), while Consequences have three sub-dimensions (Handling Benefits, Rational Benefits, Convenience Benefits) and Values have just one dimension. Also, SEM has shown a statistically significant positive relationship between A-C-V perceived by consumers of coffee in capsules. These results confirm the hypotheses developed based on the Means-End Chain Theory (MEC). Originality/value As academic contributions, this paper develops a structural model that quantitatively demonstrates the impacts of Attributes perceived by consumers of coffee in capsules on the Consequences of consumption and its effects on their Values. The present survey is the first in the literature that uses structural models contemplating A-C-V. As managerial contributions, this survey provides relevant information to the decision-making of several stakeholders of the chain of coffee in capsules.
- The moderating effect of health orientation and subjective norms on the relationship between personal values and organic food purchase intentionPublication . Oliveira, Alessandro Silva de; Campos, Rita de Cássia Leal; Quiroga Souki, Gustavo; Boas, Luiz Henrique de Barros VilasUnderstanding how organic food consumers' (OFCs) values influence their organic food purchase intention (OFPI) is paramount. This study examines the impact of OFCs ' values on OFPI and the moderating role of health orientation and subjective norms in this relationship. This study involved 307 OFCs who filled out an online form regarding attributes, consequences, and values (A-C-V), OFPI, health orientation, and subjective norms related to organic food consumption. Using PLS-SEM and the Means-End Chain Theory, results indicate that OFCs' values positively influence OFPI. Health orientation positively moderates the relationship between values and OFPI, while subjective norms negatively moderate it.
- Organic food-buying intention drivers: a study based on means-end chain theoryPublication . Oliveira, Alessandro Silva de; Quiroga Souki, Gustavo; Boas, Luiz Henrique de Barros VilasPurpose – Understanding how attributes, consequences and values (A-C-V) influence the predisposition to purchase and buying intention of organic food consumers (OFC) is crucial for its stakeholders. This study aims to (1) investigate whether OFC perceptions of the A-C-V impact their predisposition to purchase and buying intention; (2) examine the mediating effect of predisposition to purchase on the relationship between OFC personal values and their buying intentions and (3) verify whether consumers with distinct levels of organic food-buying intention perceive differently of the A-C-V, predisposition to purchase and consumption frequency. Design/methodology/approach – This quantitative study comprised 307 consumers who filled out a form about their perceptions of organic foods’ A-C-V and their consumption frequency, purchasing predisposition and buying intention. Partial least squares strutural equation modelling (PLS-SEM) tested the hypotheticalmodel that resorted to themeans-end chain (MEC) theory (Gutman, 1982). Cluster analysis based on OFC’s buying intentions compared their perceptions of the A-C-V, purchasing predisposition and consumption frequency. Findings – The OFC’s perception of the attributes of these foods impacts the consequences of their consumption and values. Such values positively influence their purchase predisposition and buying intention. Predisposition to purchase measured the relationship between OFC values and purchase intention. Three OFC clusters were identified according to their buying intentions. Such groups perceive the A-C-V singularly and have different purchasing predispositions and consumption frequencies. Originality/value – OFC values directly influence buying intentions. However, the predisposition to purchase strongly mediates the relationship between values and buying intentions, producing an indirect impact more notable than a direct one. It brings academic and managerial contributions to organic food stakeholders.
