The network perspective will help, but is comorbidity the question? A commentary on Cramer et al

Behavioral and Brain Sciences, 33:162-163.

Latent variable modeling has revealed important conundrums in the DSM classification system. We agree that the network perspective has potential to inspire new insights and resolve some of these conundrums. We note, however, that alone it cannot really help us understand etiology. Etiology, not comorbidity, is the fundamental question.
