Household food waste and theory of planned behavior: A systematic review and meta-analysis

Abstract

The darker side of food behavior is that millions of tons of food have been shown the doors of garbage.Therefore, food waste behavior needs an eye to look upon. The purpose of this research is to inculcate the concept of systematic literature review along with meta-analysis in order to examine the Theory of Planned Behavior (TPB) with respect to food waste behavior. The methodology includes Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) that is conducted for identi cation, screening and inclusion of studies. In all, twenty-six independent studies with (N = 13373) met the inclusion criteria. For validating the related literature, Random-effects meta-analysis has been applied for ascertaining average correlation among the variables. More speci cally, the present study also examines the sub-group analysis effect among TPB variables. The ndings reveal that the strongest association was observed between attitude and intention followed by subjective norms and intention, perceived behavioral control and intention, and intention and behavior. Furthermore, the subgroup analysis using multi-cultural groups explores the highest composite correlation in case other cultural groups that included country like Canada.In addition, the sample size subgroup analysis supports that the increase in sample size lead towards more strengthening of association among TPB variables. The outcomes of the present study seek to serve in the best interest of households, event management stakeholders and food policy makers.

Adoption intention and willingness to pay for electric vehicles: role of social-psychological attributes, fiscal incentives and socio-demographics

“…In light of this, we aim at testing an integrated model of consumer’s intentions to adopt EV. As per “theory of planned behavior” (TPB), behavioral intention is the best predictor of actual conduct, and it has three antecedents: attitude, subjective norm and perceived behavioral control (Ajzen, 1991; Srivastava et al. , 2023).…”

“…, 2023; Waris and Ahmed, 2020). According to Schwartz (1977), norms are actively felt “as feelings of moral obligation, not as intentions.” TPB has previously been involved in a range of environmentally friendly practices and acts, such as recycling, household food waste, purchasing organic commodities, buying energy-efficient products, living in green communities and eating at green restaurants (Amin and Tarun, 2022; Srivastava et al. , 2023; Waris and Ahmed, 2020).…”

“…Thus, it has been theorized that a variety of antecedents or predictors drive this behavioral reaction. The first determinant is “subjective norm” which specifies the perceived societal value to engage in or refrain from engaging in the action (Ajzen, 1991; Srivastava et al. , 2023; Tiwari et al.…”

“…In light of this, we aim at testing an integrated model of consumer's intentions to adopt EV. As per "theory of planned behavior" (TPB), behavioral intention is the best predictor of actual conduct, and it has three antecedents: attitude, subjective norm and perceived behavioral control (Ajzen, 1991;Srivastava et al, 2023). The "theory of reasoned action" (TRA) is succeeded by TPB as one of the best theories to explain consumer behavior (Tiwari et al, 2023), particularly pro-environmental behavior (Adnana et al, 2018;Ghaffar et al, 2023;Waris and Ahmed, 2020).…”

“…The first determinant is "subjective norm" which specifies the perceived societal value to engage in or refrain from engaging in the action (Ajzen, 1991;Srivastava et al, 2023;Tiwari et al, 2023). The second antecedent, "personal moral norm," relates to a person's belief that doing something is morally or ethically correct or not (Bamberg et al, 2007;Sang et al, 2020).…”
