A Specific Case of Non-Specificity: Longitudinal Effects of Dysfunctional Attitudes on Depressive, Eating Disorder and Aggressive Symptoms in Children and Adolescents 

Jan 2017 DOI 10.14302/issn.2476-1710.jdt-16-1324
Susanne MeiserCorresponding author

An important step in the validation of disorder-specific etiological models is the examination of the predictive specificity of proposed vulnerability factors. It may advance the understanding of the emergence of comorbidity and the identification of at risk-populations for mental disorders. To enha…
