Brain Correlates of Self-Focused Processing as a Biomarker of Treatment Response

The purpose of this study is to determine whether neuroimaging-based markers of maladaptive
self-focused processing are better predictors of treatment response to cognitive-behavioral
therapy than behavioral markers.

First, the investigators propose to identify the neural correlates of self-focused
processing. The investigators will assess baseline resting state connectivity within the
default network, as well as regional brain activation using a well-validated event-related
fMRI task that manipulates self-focused processing in patients with body dysmorphic and
socially anxious symptoms, compared to healthy controls. This clinical sample was selected
because such patients display heightened self-focused attention, and sampling individuals
across these symptom dimensions will ensure greater variability on this dimension of
maladaptive self-focused processing. Second, the investigators will examine the neural
correlates of self-focused processing as a predictor of treatment response. Neuroimaging data
will be acquired from patients with body dysmorphic and socially anxious symptoms during two
scan sessions, before and after 12 weeks of individual cognitive behavioral therapy, and
compared with healthy controls scanned twice at a 12 week interval. Finally, the
investigators will compare the prediction of treatment response between neural measures and
behavioral measures of self-focused processing. The investigators will assess the behavioral
correlates of self-focused processing using a self-reference effect paradigm, and assess
their relation to treatment response. If the investigators hypotheses are borne out, the
investigators will have new targets for treatment, a method to identify promising candidates
for treatment, and sensitive surrogate markers of treatment response.

Inclusion Criteria:

- Men and women, age 22-45

- For healthy controls only: no current or lifetime history of psychiatric disorders,
and score of below 1 SD of mean on the SCS-R

- Current or past manic/hypomanic episode or psychotic symptoms

- Active alcohol and substance dependence (as assessed by the SCID-5-RV

- Current use of psychotropic medications, except antidepressants taken at a stable dose
for 2 weeks, to maximize generalizability of sample

- Current CBT and/or formal mindfulness/meditation training
