“…Several researches have studied the psychometric properties of the GAI, including MárquezGonzález, Losada, FernándezFernández, & Pachana (2012), Gerolimatos, Gregg, & Edelstein (2013), Massena, Bom de Araújo, Pachana, & Camozzato de Pádua (2014), Yan, Xin, Wang, & Tang (2014), Gould, Segal, Yochim, Pachana, Byrne & Beaudreau (2014), Ball, Lipsius, & Escobar (2015), and Guan (2016). In general, they found that the GAI presents good psychometric properties such as internal consistency indexes (Cronbach's α) ranging from 0.91 to 0.93 among healthy communitydwelling older adults and in the psychogeriatric sample, respec tively.…”
