The comparison between the average and normal deviation of the overall quality of life before and after education, in the intervention group, showed that overall quality of life increased from 40.30 ± 7.25 to 47.12 ± 9.28, and the paired t-test revealed that this variation was statistically important (p = 0.001). Additionally, the comparison between the 8 concepts of the quality of life showed the differences in all demotions: role restriction due to mental issues (0.005), role limitations because of physical health concerns, (0.02), general mental health (0.01), physical functioning (0.04) and social functioning (0.02), bodily disorder (0.02), general health perception (0.005), vitality (energy, fatigue) (0.002), being significantly increased (Table 5).
