Convergent validity was tested through correlation analyses with the , the , the , the , and the . According to the CFA results, the structure of the Russian version differs from the original one slightly (item 1 was moved from the subscale to the subscale and item 4 was excluded); however, the modified factor model showed the best absolute and comparative fit statistics [CFI = 0.961, TLI = 0.949, RMSEA = 0.050 (90% CI [0.40; 0.60]) and SRMR = 0.037]. The reliability (McDonald's Omega) of the subscales was satisfactory and ranged from 0.78 to 0.84. It was revealed that youth are more likely to have high scores on and than adults.
