Left-Behind Experience and Behavior Problems Among Adolescents: Multiple Mediating Effects of Social Support and Sleep Quality.

We found that social support and sleep quality had a series of multiple mediating effects in the pathway from left-behind experience to behavior problems, and both significantly moderated behavior problems. Therefore, we suggest that we should pay more attention to students' psychological status and improve their use of social support for left-behind adolescents, in addition to giving more external social support. And paying attention to their sleep problems to reduce the occurrence of behavior problems, considering that their psychological development is not mature.
