“…Also, if definitions of 'lower SES' were provided, they varied a lot between studies. To describe low-income participants, studies for example applied a threshold of <100% (e.g., Nieves et al, 2022), ≤185% (e.g., Bird & McClelland, 2017;Seguin-Fowler et al, 2021;Skalka, 2020), <200% (e.g., Hayashi et al, 2010;Ritten et al, 2016) or <250% (e.g., Gray et al, 2021) of the federal poverty line.
