“…The majority of the studies (N = 16) used a cross-sectional research design, with only three studies using a longitudinal approach (Demerouti et al, 2000;Grau et al, 2009;Kim et al, 2011). All studies employed quantitative research methods and ranged in statistical analysis from correlation (Bakir, Ozer, Ozcan, Cetin, & Fedai, 2010;Bhana & Haffejee, 1996;Iglesias & de Bengoa Vallejo, 2013;Maslach & Florian, 1988) and t tests for difference between groups (Jayaratne, Chess, & Kunkel, 1986) to discriminant analysis (Bennet, Kelaher, & Ross, 1993) Jahrami et al, 2013;Kim, 2011;Laschinger & Grau, 2012;Um & Harrison, 1998).…”
