Key takeaways
-
The three categories internalizing, externalizing, and thought disorder was an attempt to sort diagnoses into three overarching categories. Some problems:
-
Correlations were very high even across these domains
-
Longitudinal data showed that one diagnosis at time 1 predicted the same disorder, but also other disorders at later time points
-
Heritability of psychiatric disorders is strong, but with very little specificity
-
Importantly, we don’t know about the causal directions here.
