“…Since previous scholars have reported direct and indirect positive relations between gratitude, forgiveness, happiness, and prosocial behavior (Meier and Stutzer, 2008;Rudd et al, 2014;Light et al, 2015;Sulemana, 2016;Riek and DeWit, 2018;Yost-Dubrow and Dunham, 2018), a positive relationship between these variables and prosocial behavior in bullying was anticipated. Moreover, prosocial behavior was expected to influence character strengths and happiness, as previous empirical evidence has shown (Lerner et al, 2003;Dunn et al, 2014;Aknin et al, 2015;Carlo et al, 2015;Fu et al, 2017;Al-yaaribi et al, 2018;Bieda et al, 2019). Finally, no hypothesis was made about the effect of gender and adolescence stage in the proposed model due to the fact that the current literature is inconclusive and even contradictory (Carlo et al, 2007(Carlo et al, , 2015Luengo Kanacri et al, 2013;Flynn et al, 2014;Van der Graaff et al, 2014;Padilla-Walker et al, 2018).…”
