Preventing Behavioral Disorders via Supporting Social and Emotional Competence at Preschool Age.

Background: 13-18% of all preschool children have severe behavioral problems at least transiently, sometimes with long-term adverse consequences. In this study, the social training program "Lubo aus dem All! - Vorschulalter" (Lubo from Outer Space, Preschool Version) was evaluated in a kindergarten setting.

Methods: 15 kindergartens were randomly assigned to either an intervention group or a control group, in a 2:1 ratio.
