Because this work did not focus on causal relationships (above), the implications of our findings for treatment are necessarily qualified. With that said, the thinking behind our hypotheses and the results obtained mesh well with the nascent trans-diagnostic treatment movement. It has been well known for several decades that all of the internalizing disorders are likely to be responsive to serotonergic drugs such as SSRI’s (Tang et al., 2009). More recently, innovators in the area of psychological treatments such as cognitive-behavioral therapy have made similar transdiagnostic observations (Ellard et al., 2010). Because its treatments aim at core pathological features shared across a range of internalizing disorders, the trans-diagnostic treatment approach strikes us as the appropriate place to begin the effort to link the present findings to clinical innovations
