Much of my early research focused on depression and anxiety in older adults, including depression in Alzheimer disease caregivers, suicidality in older African-Americans, depression and anxiety in older adult psychiatric outpatients, and chronic benzodiazepine use in older primary care patients. This work included my master’s thesis, doctoral dissertation, and first National Institute of Mental Health (NIMH) grant. This research was important in documenting not only the occurrence of depression and anxiety in these particular populations but also the variables that were uniquely associated with each.

A significant amount of my research and related publications focus specifically on the prevalence, phenomenology, assessment and treatment of older adult trauma survivors. In addition to conducting original quantitative and qualitative research on this population, I have completed systematic reviews of the literature on several older traumatized subgroups including older adults who experienced natural and man-made disasters, and older women who have been sexually or physically assaulted. This work has documented how trauma experienced early in life can continue to have devastating mental and physical problems in older adults decades later and how traumatic stress related disorders can be reliably assessed and effectively treated.

A large part of my programmatic research portfolio has examined the dissemination and implementation of evidence-based psychotherapies, particularly those for trauma survivors with posttraumatic stress disorder (PTSD). Three of my four NIMH grants have focused on this topic and have resulted in evidence-based recommendations on how to overcome barriers to achieving effective treatments in the community.

Relatedly a part of my professional efforts have involved understanding how mental health providers clinically work with trauma survivors. My group and I spearheaded a national consensus conference to articulate key knowledge, attitudes and skills that providers working with traumatized populations must have from a competency perspective. These are broad based and include not only evidence-based treatments but basic science information on traumatic stress, ethical issues and diversity effects.
