About Me

Measuring psychological constructs that cannot be directly observed is a challenging process. When they can be observed, measurement is often costly and not realistic in low-income settings. Measuring psychopathology and interpersonal constructs, such as parenting, is critical for clinical settings, and it has been a primary focus of my research. For instance, recently, despite years of use of the Bayley Infant Neurodevelopmental Screener (BINS) in South Africa among HIV-exposed infants, I was the first to replicate the original factor structure of the BINS in this context.¹ I also developed a measure to optimize evaluation of the Prevention of Mother-to-Child HIV Transmission (PMTCT) program and its effectiveness.² In the United States, under the mentorship of Dr. Shaffer, I developed a preliminary version of the Regulating Emotions in Parenting Scale (REPS), which has utility promoting greater specificity in parenting interventions.³ I have also collaborated with other researchers on optimizing other measures for use in low-income settings, international contexts, and racially and ethnically diverse samples⁴:

Another area of research focus is psychopathology among understudied, underserved, and underprivileged groups, which informs my research on measurement. Under the mentorship of Drs. Anne Shaffer and Deborah Jones, I examined cross-lagged effects between depressive symptoms and intimate partner violence among women living with HIV in South Africa,¹ as well as factors associated with suicidal ideation in this group.² Working with both Drs. Jones and Alcaide, I found that the use of efavirenz, an antiretroviral medication, predicted suicidal ideation in pregnant women living with HIV.³ These findings had important implications for women’s mental health and their infants’ socioemotional development. In the United States, under the mentorship of Drs. Jones and Kumar, I published a manuscript showing an association between child maltreatment and depression, an association that was moderated by levels of social support, which differed by whether the individuals were infected with HIV.⁴ These projects resulted in the following selected publications:

Consistent with my interest on the role of parenting factors that predict infant development and health in at-risk environments, several of my publications have examined the role of perinatal intimate partner violence and perinatal depression on neurodevelopmental outcomes among HIV-exposed children born to women living with HIV in rural South Africa under the direction of Dr. Jones.^1,2 I have also collaborated on projects, contributing to the data analysis, that aim to optimize infant health by preventing mother-to-child HIV transmission.^3,4 Under the direction of Dr. Alcaide, I examined biological maternal factors that contribute to neurodevelopmental delays among HIV-exposed uninfected infants. In working with Dr. Cook, I learned Bayesian analyses in the process of identifying psychosocial factors predicting nonadherence to infant HIV medication regimen, which increases the risk for infant HIV infection.

As a graduate student, I have focused on the measurement of family-related constructs to address the increasing need for psychometrically sound measures in parenting. In this process, I have sought several quantitative training opportunities to enhance the psychometric properties of measures in research and clinical settings, particularly those used with vulnerable families. I have also sought extensive training opportunities in qualitative research and mixed methods research, which I plan to use in the proposed project.^1-4 As part of my training, I have eagerly sought exposure to different methods, cultural contexts, and worked with understudied, underserved, and underprivileged groups under the mentorship of several accomplished researchers.
