Dr. Williams is currently involved in three treatment outcome studies at the Center for the Treatment and Study of Anxiety, directed by Dr. Edna Foa. The first is a randomized trial of exposure and response prevention (EX/RP) or Risperdal for people with OCD who are having only a partial response to SRIs. The second is a study for people with PTSD and alcohol dependence. The third study is a pilot project to treat cigarette smokers with PTSD.
More information about these studies is available at the CTSA website.

The Internet as a Research Tool and Intervention
Dr. Williams' dissertation work was a project investigating psychological assessment procedures used to study obsessive compulsive disorder (OCD). Of particular interest was the validity of OCD questionnaires, such as the Maudsley Obsessional-Compulsive Inventory (MOCI) and Padua Inventory, when employed with US ethnic minority groups. Prior work had indicated the MOCI lacks predictive validity for African-Americans (Thomas, Turkheimer, & Oltmanns, 2000). My masters thesis documented similar issues with the Padua Inventory (Williams, Turkheimer, Schmidt, & Oltmanns, 2005).
Dr. Williams' doctoral work explained the reasons for Black-White differences in mean scores from the Padua Inventory contamination scale and the Obsessive-Compulsive Inventory (OCI-R) washing scale. Her dissertation was a compilation of four studies — a psychometric study, a laboratory study, an Internet study, and a qualitative study. The Internet study was recently published in a research journal; data was collected through an NSF project called Time-Sharing for the Social Sciences (TESS).
