The need to reduce consumption is evident, and a way of achieving this is through austerity and frugal practices. The aim of this research was to advance the understanding of frugal behavior and its relation to consumer identities, and to analyze any possible mediating effects of environmental self-identity. In Study 1 (n = 492), the factor structure of the consumer identities scale was tested and three distinct identities were defined: moral, wasteful, and thrifty consumer identities. In Study 2 (n = 500), the influence of consumer identities on frugal behavior was studied and the possible mediating effect of environmental self-identity was analyzed. Environmental self-identity completely mediated the relationship between moral identity and frugal behavior and partially mediated the relationships of both wasteful and thrifty identities with frugal behavior. The model was able to predict 27.6% of the variance of environmental self-identity and 47.9% of the variance of frugal behavior, with a strong influence by the thrifty consumer identity. This emphasizes the economic dimension of frugal consumption patterns and the importance of considering how people view themselves, both as individuals and as consumers, in order to more effectively engage and maintain long-term sustainable frugal actions.

Meaningful work is the subjective experience that work has meaning and is understood as an avenue for personal development, from a eudaimonic point of view. The aim of this study is to adapt the WAMI scale of meaningful work to Spanish, as well as to explore its relationship with job and life satisfaction. Two independent studies were developed. A first study analyzed the consistency of the original factorial model using a sample of Spanish varied workers (N = 350) through a confirmatory factor analysis. Results show an adequate replication of the original model and the validity of the Spanish version. A second study addressed the predictive capacity of the scale in relation to two satisfaction measures in a sample of Spanish health workers (N=312), through a mediation analysis. The relationship between meaningful work and job satisfaction is mediated by life satisfaction. The idea of meaningful work as a eudaimonic construct discards it as a variable resulting from or consequence of work, as it is an inherent part of occupational activity itself.

Purpose: The paper aims to determine whether people with different eating patterns, specifically meat-free diets, engage in other types of eco-friendly behaviours and whether the meanings attributed to food allow for a better understanding of this relationship.Design/methodology/approach: Data were collected between 2019 and 2020, on the island of Tenerife, Canary Islands, Spain. Different instruments were used: The meaning of food in life questionnaire (MFLQ; Arbit et al., 2017); the dietarian identity questionnaire (DIQ; Rosenfeld and Burrow, 2018) and the frugal behaviour scale (Muiños et al., 2015) and two items were used to identify the frequency with which participants purchased ecological or second-hand products. The final sample consisted of 202 participants who ate a vegan, vegetarian or omnivorous diet. Spearman's Correlations were performed and the Kruskal–Wallis statistical test was used.Findings: People with a vegan or vegetarian diet purchased ecological (p ≤ 0.001) and second-hand products (p = 0.006) more frequently compared to omnivores. Furthermore, the meanings attributed to food, specifically the moral, sacred and health meanings, were related to differences in eating patterns (p ≤ 0.001), while also being related to some eco-friendly purchase and consumption behaviours. Lastly, frugal behaviour was only found to be related to the health factor of meaning in food (rs = 0.27).Research limitations/implications: The measurement used to evaluate the purchase of ecological and second-hand products is very simple/the role of the meaning of food in guiding more eco-friendly behaviours and promoting less ecologically impactful eating patterns.Originality/value: The study provides valuable information on how vegan, vegetarian and omnivorous diets relate to eco-friendly behaviours.

The aim of this study is to adapt and validate the Dietarian Identity Questionnaire (DIQ) into the Spanish context. In an initial study, a confirmatory factor analysis was performed, obtaining good validity and goodness-of-fit indices (CMIN/DF = 2.026; CFI = .976; NNFI = .972; SRMR = .054 and RMSEA = .057). In a second study, evidence of validity based on the relationship with other variables was analysed using the ‘Meaning of Food in Life’ questionnaire. Correlations were made and differences between people with a vegan (N = 43), vegetarian (N = 44) and omnivorous (N = 115) diet were analysed. The results indicate that vegans and vegetarians differ from omnivores in all identity factors (p = ≤ .001). In addition, differences were found between vegans and vegetarians in the Public Regard (p = .035), Outgroup Regard (p = .036) and Moral Motivation (p = .036) factors. DIQ is a good instrument that can be used in studies on food choices and sustainability.

High levels of textile consumption and waste have made the fashion industry one of the most polluting sectors, highlighting the need to understand the factors influencing clothing consumption. This study aims to develop a comprehensive instrument to measure clothing consumption, adapt the Clothing Style Confidence Scale for use in a Spanish-speaking context, and explore explanatory models of sustainable clothing consumption. Using a convenience sample of 500 participants, including psychology undergraduate students from a Spanish public university, data was collected through an online questionnaire. The new instrument includes four dimensions: quantity of consumption, focus on fashion, focus on quality, and product disposal. The Clothing Style Confidence Scale was adapted through confirmatory factor analysis. Structural equation modeling was used to test a model examining the influence of consumer identities, environmental self-identity, frugal behavior, and clothing style confidence. The model explained 66% of the variance in clothing consumption, with style confidence and wasteful consumer identity as the strongest predictors.
