In the current issue of this journal, Rapee (2013) reports that the incidence of internalizing disorders was reduced as a result of a brief parent centered intervention amongst adolescents who as young children were characterized with the temperament of behavioral inhibition (BI). The intervention was administered when children were 3 to 5 years of age and consisted of a short parent training program (i.e., six 90-min group sessions). Now, some 10 years later, those adolescents whose parents participated in the intervention were less likely to develop both anxiety and depressive disorders. Although the current study demonstrated prevention/intervention effects, the approach raises a number of issues in need of careful consideration, which are addressed in this commentary.
