The context of this research is Bolivia, a country is located between the Andes Mountain range and the Amazon rainforest in South America. It currently has 12,224,110 inhabitants, with more than 40 indigenous nationalities and a poverty level of around 36.4% in 2021 (World Bank, 2023). For data collection, two investigators conducted the questionnaire-based interviews between September to November 2018. We analysed data from 225 questionnaire-based answers of IWEs of the Quechua community of Bolivia. We conducted a factorial and regression analysis to test our hypothesis, finding the significant factors affecting IWEs’ success.
