“…The trait of cheerfulness is primarily predicted by high extraversion, emotional stability, and agreeableness. While these results are generally in line with our expectations and the results of previous studies (Carretero-Dios et al, 2014;Lau, Chiesi, Saklofske, & Yan, 2019;Ruch & Köhler, 1998;Wrench & McCroskey, 2001), it was not predicted that the correlation of cheerfulness with agreeableness would be of the same size as that with extraversion. However, "socially warm humor," as measured by the HBQD (Craik, Lampert, & Nelson, 1996), and "affiliative humor," as measured by the HSQ (Martin, Puhlik-Doris, Larsen, Gray, & Weir, 2003), are typical of cheerful individuals (Martin et al, 2003;Ruch et al, 2011) and these dimensions overlap with agreeableness (e.g., Mendiburo-Seguel, Páez, & Martínez-Sánchez, 2015), which makes a strong link between cheerfulness and agreeableness plausible.…”
