“…Survey items aligned with variables and measures were drawn from extant risk perception literature further adapted for water risks and the context of Ontario (Slimak and Dietz 2006, Krewski et al 2006, 2008, Dupont et al 2014, Bouman et al 2018, Robinson 2018, Thistlethwaite et al 2018, Mumbi and Watanabe 2020, Grima et al 2021. Operationalizing our theoretical framework, water risk perception factors (independent variables) to be examined included Nature of Risk (different water issues, likelihood, drivers, extent of integration), Attitudes (confidence, scope, controllability, equity, impact awareness, benefits, previous exposure to water issues, overall concern, and urgency), Knowledge (assessment of experience, knowledge in different sectors, source of knowledge), Values and beliefs (biospheric, altruistic, egoistic, technological optimism), Trust (in institutions to manage water risks), and Sociocultural demographic characteristics (cultural importance of water, sector, discipline, professional role, gender, ethnicity, location).…”
