The purpose of this clinical trial is to answer the question: can the investigators predict which adults with social anxiety disorder (SAD) will successfully respond to treatment? To answer this question, the investigators plan to recruit 190 adult participants who experience extreme forms of social anxiety to undergo brain imaging before and after 12 weeks of group cognitive behavioral therapy (CBT). Adults in the SAD group who do not respond enough to group CBT may be offered the opportunity to complete an additional 12 weeks of individual CBT while receiving SSRI medication (sertraline, see below) for SAD.
Data collected from participants who experience anxiety will be compared to a group of 50 participants with little or no social anxiety, who will serve as a comparison group.
Outpatients with a primary psychiatric complaint (designated by the patient as the most important source of current distress) of social anxiety with social interaction fear as defined by an Liebowitz Social Anxiety Scale (LSAS) score >= 60.
Overall clinical severity of at least mild as defined by Clinical Global Impressions Scale (CGI-S; Zaider et al., 2003) of at least 3.
Medical history interview and laboratory findings without clinically significant abnormalities.
Willingness and ability to participate in the informed consent process and comply with the requirements of the study protocol.
A lifetime history of bipolar disorder, schizophrenia, psychosis, delusional disorders or obsessive-compulsive disorder; an eating disorder in the past 6 months; organic brain syndrome, intellectual disability, or other cognitive dysfunction that could interfere with capacity to engage in therapy; a history of substance or alcohol abuse or dependence (other than nicotine) in the last 6 months or otherwise unable to commit to refraining from alcohol, marijuana, and stimulant use during the acute period of study participation.
. Patients with significant suicidal ideation Montgomery-Åsberg Depression Rating Scale (10 items, self-report) or who have enacted suicidal behaviors within 6 months prior to intake will be excluded from study participation and referred for appropriate clinical intervention.
Patients can be taking a concurrent psychotropic medication (e.g., antidepressants, anxiolytics, beta blockers, sertraline), but the dose must be stabilized for at least 2 weeks prior to initiation of randomized treatment.
Significant personality dysfunction likely to interfere with study participation.
