3.2 Cronbach’s alpha coefficients of the SSQOL and the SF-36 Scales
Cronbach’s alpha coefficients for SSQOL and SF-36 scales ranged from 0.74 to 0.97, and from 0,59 to 0.95, respectively, which supports the presence of a robust internal consistency. When the similar subdimensions of the scales were examined, it was seen that the Cronbach’s alpha coefficient of SF-36 was lower than that of SSQOL (SF <SFR, VT˂E, MH˂ M). Cronbach’s alpha coefficient of SF-36 was found to be 0.70 in three subdimensions (VT, SF, MH). However, the Cronbach’s alpha coefficient of the SSQOL scale was> 0.74 in all subscales (Table 2).
