Tamra Loeb

Associate Research Psychologist

Dr. Loeb works at the Department of Psychiatry and Biobehavioral Sciences at UCLA, and has most recently been an Investigator for a study housed in the UCLA Center for Culture, Trauma, and Mental Health Disparities. In this capacity, she examines the impact that sociocultural factors, economic status, ethnicity, gender, and cumulative histories of child trauma and adversity have on mental and physical health among ethnically diverse samples of men and women. This background in research has provided her with rich opportunities to conceptualize complex relationships among psychological variables, as well as conduct interviews and collect both quantitative and qualitative data. She is particularly interested in issues concerning the measurement of child sexual abuse.

Dr. Loeb has also recently worked on the Fogarty International Collaborative Program, a multi-disciplinary training program for research in trauma, injury and the effects on health and mental health.  Dr. Loeb mentored fellows and assisted them in training to conduct research that addressed the biological, social and psychological factors related to trauma, injury and its effects.
Dr. Loeb was the Principal Investigator for the NIMH-funded grant “Disclosure & Appraisal of CSA: Relationships with PTSD, Depression and Biomarkers”, housed in the The Center for Culture, Trauma and Mental Health Disparities.  This study investigated the relationship between the severity of child sexual abuse, disclosure and appraisal of child sexual abuse on depression, PTSD, and biological indicators of stress among African American and Latino women and resulted in the publication of numerous manuscripts.

Dr. Loeb provided data management and coding of sexual abuse data for the NIHM-funded     “HIV/STD Risk Reduction in African American Couples”, an interactive U10 Government Cooperative with University of Pennsylvania, Columbia and Emory Universities.  The study was a five-year randomized clinical trial with African American, serodiscordant couples.
Dorothy Chin

Associate Research Psychologist

Dr. Dorothy Chin works at the Department of Psychiatry and Biobehavioral Sciences at UCLA.  After she conpleted her post-doctoral fellowship on the Biobehavioral Aspects of HIV/AIDS at UCLA in 1999, she published the first HIV behavioral risk study on Asian Pacific-Islander (API) American women, describing how risks are assessed and defined among this under-researched population.  Since then, she has expanded her research on HIV risk behaviors to include other under-researched and underserved populations, including African-American and Latina women and those with childhood sexual abuse and histories of other, cumulative adversities.  Her body of work rests on a background in cross-cultural and clinical psychology, which includes expertise in the theory in cultural and cross-cultural psychopathology and cross-cultural research methods.  Within these spheres, she has published articles about the sociocultural influences of psychopathology, taking an international cross-cultural approach, as well as papers on cross-cultural qualitative methodology and psychometric evaluations in minority and under-researched groups.  

Dr. Chin is currently affiliated with the UCLA Center for Culture, Trauma, and Mental Health Disparities, which examines the effects of trauma on psychological functioning, including depression, anxiety, and PTSD among primarily ethnic minority populations.   Prior to that, she was Principal Investigator of a two-year grant Healing Our Women (HOW) Project, a capacity-building effort funded by the California Endowmnet to increase integrated HIV-trauma interventions in community-based organizations in Los Angeles.  After being implemented in New York City in a collaboration with Planned Parenthood, the HOW curriculum has since been reviewed and designated by the CDC as an evidenced-based intervention demonstrated to be effective in the community.  Dr. Chin was also Co-Investigator of a NIMH-funded four-year grant to test a model of HIV risk-reduction among women in L.A. County. 

Dr. Chin has been a regular reviewer for several journals, including Journal of Traumatic Stress, Psychological Assessment, and Psychological Trauma: Theory, Research, Practice, and Policy, and have been on the Editoral Board for Psychology of Women Quarterly, Cultural Diversity and Ethnic Minority Psychology, and Psychological Assessment.  She has been an ad-hoc reviewer for the Demography and Populations Studies Branch of the National Institute of Child Health and Development (NICHD), as well as a regular seed grant reviewer for the UCLA AIDS Institute.  She has also mentored doctoral-level scholars from South Africa as part of the Fogarty International International Collaborative Program, a multi-disciplinary training program for research in trauma and the effects on health and mental health.
