“…The original component or long trait form of the STCI (i.e., STCI-T106) in German, Chinese, and English consists of 106 items in a 4-point Likert scale for the three traits of cheerfulness (STCI-T CH; 38 items), seriousness (37 items), and bad mood (31 items; Chen, Ruch, & Li, 2016;Ruch et al, 1996;Ruch & Hofmann, 2012). A standard trait version has also been created with 60 items derived from the larger set of 106 items to provide a more economic assessment of the three traits and this version has been widely used and translated in 13 languages (Chen et al, 2016;Ruch & Hofmann, 2012). Chen et al (2016) translated the STCI-T106 from English to Chinese but instead of using the same set of items as the other standard versions with 60 items (i.e., 20 items per subscale), the authors selected items from the long form for their own version with cheerfulness (21 items), seriousness (21 items), and bad mood (18 items).…”
