Indirect effect of each mediate pathway from IA to suicidal behavior.

Path	UC (SE)	SC (SE)	p-Value	Effect size
Total indirect effects	0.109 (0.003)	0.309 (0.009)	< 0.001	100%
IA → insomnia → SB	0.036 (0.002)	0.103 (0.007)	< 0.001	33.3%
IA → DAS → SB	0.044 (0.002)	0.125 (0.006)	< 0.001	40.5%
IA → insomnia → DAS → SB	0.029 (0.001)	0.081 (0.004)	< 0.001	26.2%

Effect size was calculated using the ratio of the total mediating effect.

UC, unstandardized coefficients; SC, standardized coefficient; SE, standard error; IA, Internet addiction; DAS, depression, anxiety, and stress; SB, suicidal behavior.
