Comparing family, friends and satisfaction with school experience as predictors of SWB in children who have and have not made the transition to middle school in different countries

The overall analysis of the results from the two models indicates that support agents (family and friends) are significant to SBW before and after the transition to middle school period. In concrete, friend support is more important than family support to 10 and 12-year-old children. Nevertheless, satisfaction with school experience behaves as a mediator between friend support, family support and SWB, and has the greatest effect on SWB at both ages. Finally, differences observed in the invariance analysis across different countries are discussed.
