Although the interaction between Internet use status and left-behind status reached only marginal significance (β = 0.713, p < 0.1), the positive coefficient indicates that the mental health benefits of Internet use status were also attenuated in this group.
The term for the interaction between Internet use status and gender was marginally significant (β = −0.937, p < 0.1), indicating that the depressive-symptom-reducing effect of Internet use status was approximately one CES-D point greater for left-behind older men than for left-behind older women.
Accordingly, coefficients of approximately half a point or more are interpreted as substantively relevant, while differences exceeding one point are viewed as practically significant.
