Substance abuse and mental health treatments have been shown to be underutilized by Asian Americans. My research is focused on enhancing service delivery to this special population. Specifically, I am interested in utilizing primary care settings as a vehicle to engage Asian Americans in mental health and substance abuse treatment. My doctoral work at the University of Michigan focused on Asian American mental health. Other previous work includes collaboration with Dr. Lisa Meredith at the Rand Corporation on treatment of subthreshold depression by primary care providers. My current work with Dr. Janice Tsoh integrates my previous trainings with substance abuse by focusing on the development of culturally sensitive nicotine addiction and depression service delivery methods to Asian Americans.

Generally speaking, my research interests lie in the areas of tobacco initiation, maintenance, and relapse, with a focus on the development of novel and potentially more efficacious interventions for intractable smoking behavior. My specific areas of study include smoking-related expectancies and the early time course of smoking withdrawal effects. Currently, I am investigating expectancies related to smoking abstinence with the ultimate goal of improving established tobacco cessation programs by including an intervention aimed at modifying these expectancies. I am also currently exploring the clinical significance of short-term smoking withdrawal effects. In the future, I plan to study issues related to the treatment of early withdrawal via psychological and pharmacological interventions.

My research focuses on the influence of social support on treatment outcome. Specifically, I am interested in how a patient's significant other affects and is affected by the patient’s involvement in treatment, and in turn, how such systemic processes might be used to increase treatment adherence and efficacy. In my doctoral work at the University of Michigan, I examined these questions within the context of individual psychotherapy, interviewing the significant others of patients in one-on-one treatments. Subsequently, while completing a clinical postdoctoral fellowship in PTSD and Substance Abuse at the San Francisco VAMC, I was impressed by the extent to which patients made use of significant others as catalysts and touchstones for entering treatment, leaving treatment, and all points in between. My current work with Dr. Gary Humfleet at the UCSF Habit Abatement Clinic integrates my previous training by examining how partner support and social network variables relate to smoking cessation outcomes. Other projects of interest include Dr. Humfleet’s study of smoking cessation treatment for HIV-positive populations, and his work on U=Internet-based smoking cessation interventions for LGBT individuals.

Dikla is a social psychologist at the San Francisco Treatment Research Center at UCSF. Her primary area of interest involves self-regulation, the process by which people alter their states and behaviors in order to achieve a desired goal. Specifically, she is interested in the way in which individuals balance more than one act which necessitates self-control. In her doctoral work at the University at Albany she investigated this issue, guided by an operational model of self-control as a limited resource, which is consumed or depleted in the process of acts of volition.
In her current work with her primary mentor Dr. Judith Prochaska she is integrating her previous training and applying it to the investigation of co-occurring self-regulation demands in daily life. Current studies include: (1) An examination of tobacco cessation and weight control, specifically how resisting the urge to eat tempting foods may impair subsequent tobacco control; (2) An investigation of the effect of exposure to smoking scenes in films on subsequent smoking behavior, in collaboration with Dr. Stanton Glantz, Director, Center for Tobacco Control Research and Education; (3) A TRDRP-funded project testing an intervention designed to restore depleted self-control strength with positive affect, with the ultimate goal of developing potential interventions for individuals with co-occurring demands.
