Acquiring a better understanding of what drives pro-environmental and sustainable behaviour is important for both researchers and practitioners alike. The purpose of this paper is to explore the moderating role of locus of control and self-construal on the relationship between pro-environmental beliefs and pro-environmental consumer behaviour. We explicitly model the endorsement of the New Ecological Paradigm (NEP) as a predictor of three specific types of environmental behaviour—travel, purchasing and day to day activities. The results show a positive and significant association between the endorsement of NEP and a person’s pro-environmental traveling behaviour, purchasing behaviour and day to day activities. Moreover, we find that the effects are moderated by a person’s locus of control, specifically, it remains positive and significant only for people with an internal locus of control. However, we found no moderating effect of a person’s self-construal on the association between NEP and pro-environmental behaviour. The findings are important in the continuing work to understand what is limiting consumers to behave according to their beliefs. Practical and theoretical implications of the results as well as suggestions for future research are presented.

The problem of unsustainable food consumption among vulnerable residents of nursing homes who suffer from dementia is often multifaceted. From an individual perspective, people with dementia who do not finish their meals are likely to encounter serious health issues associated with malnutrition. Moreover, at the institutional level, nursing homes generate tons of nonrecoverable food waste each year, impairing not only their economic position but also the natural and social environment at large. The purpose of this study is to explore the possibility of reducing food waste in Norwegian nursing homes by appraising how large this reduction could be as one replaces traditional dining white porcelain with plates with diverse color combinations. A quasi-experimental method was adopted. The results of the pilot study were extrapolated to the annual amount of food wasted at the national level. The findings indicate that, on average, 26% of food was thrown away when served on white plates compared to only 9% when served on one of the colored plate options tested. Nationally, approximately 992.6 tons of food per year could potentially be saved with only a single change, ultimately ameliorating the unsustainable food consumption problem among residents of nursing homes.

Educating and changing consumers´ attitudes towards sustainable and more environmentally friendly holiday choices is often seen as a key challenge for the tourism industry. The primary objective of this study is, therefore, to increase our understanding of psychological mechanisms underlying consumers’ responses to communication that aims to alter their holiday behavior in a more sustainable direction. Drawing on reactance theory, as well as first- and third-person perception effects, we present an experimental study designed to test how different levels of message assertiveness (i.e., hard versus soft pressure) affect consumers’ intentions to change their traveling behavior. The results suggest that when respondents are presented with a socially desirable message, their individual intentions to change one’s holiday plans are affected to a greater extent compared to their perception of how others would react to such cuing. Furthermore, this first-person effect is most prominent under lower levels of message assertiveness, and when conveyed messages address socially desirable behavior in line with one’s current values. Hard pressure messages loaded with highly assertive prompts, on the other hand, are likely to evoke motivational reactance, especially when a consumer holds a weaker attitude towards sustainability and environmental issues. Practical and theoretical implications of the provided findings as well as avenues for future research are discussed.

Limited research has focused on consumption reduction as one potential pathway to meet sustainable development goals. This paper investigates consumers’ intentions to undertake consumption reduction through the lens of an extended theory of planned behavior (TPB), where selected individual differences, namely the need for evaluation (NE) and self-referencing (SR), are given considerable attention. In total, 226 respondents participated in this web-based survey study. The results from structural equation modeling analysis confirm that the extended theory of planned behavior effectively explains consumers’ intentions to undertake consumption reduction. Notably, the individual differences of the NE and SR each uniquely moderate the relationships within the TPB model. This study provides a theoretical contribution by integrating the selected moderators (i.e., the NE and SR) into the TPB framework, increases the TPB’s predictive power, and further provides a novel understanding of the underlying influences of individual differences on consumers’ intentions to undertake consumption reduction for the benefit of the environment. Moreover, the findings offer practical implications for policymakers and social marketers in designing tailor-made interventions and consumption reduction strategies by considering the important role of individual differences.

Followers do not passively observe leaders—they actively infer intentions, and these inferences shape their attitudinal and behavioral responses toward leader behaviors. While such attributional processes are central to social psychology, they have been largely overlooked in leadership research. Instead, leadership measurement models often conflate inferred intentions with behavioral constructs, making causal claims indeterminate. Empirical evidence, in its current form, risks misleading leadership theory into assuming causality without clarifying whether leadership outcomes result from leaders’ actions or from what followers believe they want to achieve through those actions. This conceptual entanglement introduces a unique form of endogeneity bias by embedding into behavioral measures what would otherwise be treated as an omitted explanatory variable—namely inferred intentions. This conflation is particularly salient in responsible leadership research and, when combined with challenges such as limited dimensional coverage, weak qualitative grounding, and overreliance on reflective models, poses substantial challenges to valid and reliable measurement. To address these concerns, this study develops and validates the Responsible Leadership Intentions (RLIs) Index, a new instrument designed to capture how followers evaluate a leader’s underlying intention. A multi-methods approach was adopted, combining a literature review, topic modeling of qualitative interviews, and a cross-sectional survey of service sector employees (N = 506). The RLIs index was modeled as a second-order reflective–formative construct across five distinct but complementary dimensions. The scale demonstrated strong psychometric properties and predictive power in explaining overall leader trust. This study contributes to reducing endogeneity bias in leadership research and marks a conceptual shift toward intention-based evaluations of leadership.
