“…In contrast, other studies have elected to focus on negatively valanced outcome indicators, such as depression, anxiety, anger, psychological distress, negative affectivity, and symptom distress or severity (Arnett et al, 2002; Barinkova and Mesarosova, 2013; Bartmann and Roberto, 1996; Ben-Zur et al, 2000; Bose et al, 2016). Finally, a substantial number of studies preferred to use, as outcomes, more stable personality characteristics such as optimism, hope, neuroticism, helplessness, resilience, self-efficacy, and self-concept (Lynch et al, 2001; Miller et al, 1996; Murberg et al, 2004; Peter et al, 2014; Shen et al, 2004; Strober, 2017; Sumpio et al, 2017; Tan-Kristanto and Kiropoulos, 2015; Tomberg et al, 2005; Trivedi et al, 2009). Research findings, however, have consistently demonstrated that both positively and negatively measured psychological constructs tap different conceptual domains, and are, therefore, largely independent in nature (Diener and Emmons, 1984; Watson et al, 1988).…”
