“…The Hope Scale (Snyder et al, 1996) was the most used instrument to evaluate hope in the studies (six out of ten). Other evaluation methods were: the Emotion Scale (Richman et al, 2005), individual qualitative interviews (Halding and Heggdal, 2012), the Beck Hopelessness Scale (Johnson et al, 2001), and the Basic Hope Inventory (Hawro et al, 2014). As for the studies that addressed both constructs, the following instruments were used: the Hope Scale Optimism–Affective valence of future perspectives scale (Schöllgen et al, 2011); the Life Orientation Test, the Gottschalk Hope Scale (Scioli et al, 1997); and the Chinese version of the Life Orientation Test and Hope Scale (Scheier and Carver, 1985; Scheier et al, 1994; Snyder et al, 1996; Scioli et al, 1997; Johnson et al, 2001; Kubzansky et al, 2001, 2002; Giltay et al, 2004; Richman et al, 2005; Hou et al, 2010; Schöllgen et al, 2011; Halding and Heggdal, 2012; Hawro et al, 2014).…”
