Abstract: Starting with John Bowlby’s attachment theory, by using Waters-Deane Attachment Q-Set, the authors screened out 3 insecurity attachment type left-behind children, and according to their insecurity attachment charac-teristics and their parents’ occupation particularities, designed parent-child sports games to carry out action-specific intervention on them. In this research, single-testee experiment design was used, before the intervention, the testees were multi-point evaluated, so as to acquire a stable baseline, after the intervention and after the intervention was removed, the testees were multi-point evaluated, so as to acquire the testees’ clear changes at each stage. The re-search results indicate the followings: a parent-child sports game participated in by the parents can make the par-ent-child relationship closer, give the insecurity attachment type left-behind child more sense of security, and enable him/her to participated in group activities in a more initiative and confident way; parent-child sports games have positive intervention effects on the issue of left-behind children’s insecurity attachment behaviors.
