The most outstanding social factors are: children-parent relationship, parent relationship, maternal depression, siblings and classmates interaction, school achievement and the number of negative events. Most of these factors work as the previous ones (maternal depression, personal structure) whereas others do it as tigers, coming from the environment (negative events, bad relationships) or become consequences (achievement, problem disorders). Nevertheless, all of them work in a complex interaction. The results are very similar to other data obtained in different countries and cultures, which indicates that depression is a homogenous dysfunctional reaction and with similar risk factors.
