How risk perception regarding the COVID-19 pandemic affected household food waste: Evidence from Brazil

Sustainable food consumption across Western and non-Western cultures: a scoping review considering the theory of planned behaviour

“…Compared to the other TPB factors, subjective norms were the least important predictor for 21 studies across both cultures (Aktas et al, 2018;Barone et al, 2019;Borusiak et al, 2022;Canova et al, 2020a,b;Chang et al, 2022;Çoker & van der Linden, 2020;Deliberador et al, 2023;Dinc-Cavlak & Ozdemir, 2022;Dorce et al, 2021;De Gavelle et al, 2019;Graham-Rowe et al, 2015;Jia et al, 2022;Kirmani et al, 2023;Lorenz et al, 2017;Ng et al, 2021;Rees et al, 2018;Soorani & Ahmadvand, 2019;Sultan et al, 2020;Testa et al, 2019;Vassallo et al, 2016;Watanabe et al, 2021). Our synthesis indicates that subjective norms are not as important as attitudes or PBC, although Western cultures may be influenced by subjective norms more than Non-Western cultures, especially for organic food purchases and potentially meat consumption.…”

“…PBC. PBC was the most influential factor of intentions for 18 studies across Western and Non-Western cultures, particularly for food waste (Abu Hatab et al, 2022;Ashraf et al, 2019;Carfora et al, 2017;Chang et al, 2022;Chen, 2021;Cos ¸kun & Filimonau, 2021;Deliberador et al, 2023;Govindan et al, 2022;Liao et al, 2018;Lorenz et al, 2017;Nair, 2021;Oehman et al, 2022;Schmidt, 2019;Soorani & Ahmadvand, 2019;Tewari et al, 2022;Watanabe et al, 2021).
