Subjective Happiness (SHS)
Participants of the control group presented statically higher scores in the SHS at T1 and T2 in the third (p=0,008) and forth (p=0,002) items of the scale, when compared with the experimental group (Table 2). 
Comparison of the SHS scores between T1 and T2 revealed a significantly lower score in the control group at T2 in the first item of the scale (p=0.014). On the contrary, in the experimental group statistically significant higher scores were detected in items “In general, I consider myself…” and “Compared to most of my peers, I consider myself…” at T2 (p= 0,046 and p= 0,014 respectively) when compared with T1(Table 3).
