In addition, a few studies found significant associations between spirituality wellbeing, ambiguity intolerance, and happiness in elderly (Argyle & Hills, 2000;Boonroungrut & Worakul, 2009;de Guzman, Lacao & Larracas, 2015;Gomez & Fisher, 2003). According to aforesaid theories in spirituality well-being (Fisher, 2000(Fisher, , 1998Fisher et al, 2000;Laubmeier et al, 2004), uncertainty intolerance (Anderson et al, 2019;Buhr & Dugas, 2009;de Guzman et al, 2015;Nuevo et al, 2009) and happiness (Veenhoven, 2012, Diener, 2006Diener et al 1999); this study suggests that spirituality well-being and uncertainty tolerance can help individuals to experience more happiness in elderly.…”
