My research examines the longitudinal pathways from child maltreatment to the onset of adverse health outcomes in childhood, adolescence and young adulthood. This work uses both experimental and observational research to identify the mechanisms of various outcomes present in the child maltreatment population across multiple levels of analysis (e.g. psychological, biological, familial). A central translational goal of this research then is to develop novel prevention programs and optimize existing clinical interventions by targeting putative risk and protective mechanisms more directly and effectively. Thus, prevention, clinical trials and dissemination research are current interests in the lab. Active projects where graduate and undergraduate students play an active role include:
The Life Events and Reactions Study (LEARS; Shenk, PI). LEARS is a genetic case control association study examining the genetic and epigenetic mechanisms associated with the onset of psychiatric disorders in the child maltreatment population. Children between the ages of 8 and 15 years of age who have experienced substantiated child maltreatment are currently being recruited for this study. Graduate and undergraduate students collect biospecimens (oral fluid, buccal swab) and administer a structured psychiatric interview determining the presence and course of multiple disorders. Students are also actively involved in the entry, coding, and cleaning of data in preparation for eventual analysis. Results from this study will provide insight into the genetic, epigenetic, and psychological contributions for these disorders in the child maltreatment population so that interventions targeting these processes can be developed or applied more effectively. This multi-site project is funded by a KL2 award from Penn State.
Selective Prevention of Psychiatric Disorders Subsequent to Child Maltreatment (Shenk, PI). Recent research on the etiology of psychiatric disorders suggests that child maltreatment affects a circumscribed set of centralized risk mechanisms, known as transdiagnostic mechanisms, responsible for the increased incidences of multiple psychiatric disorders in this population. This recently funded and IRB-approved study is testing the feasibility of a newly developed selective prevention program that aims to alter transdiagnostic mechanisms in order to optimize treatment effects and reduce the incidences of multiple psychiatric disorders subsequent to child maltreatment. Graduate students and clinical staff are developing treatment protocols, beginning recruitment efforts, organizing treatment evaluation materials, and developing databases.
The Female Growth and Development Study (FGDS; Shenk, Co-I). FGDS is a 30-year prospective cohort study of the long-term effects of childhood sexual abuse (CSA) on subsequent female health outcomes. Research from this study has provided some of the most definitive results to date on the adverse developmental effects following CSA, including neuroendocrine disruption, premature cognitive aging, sexual risk behaviors, and pubertal timing. Recent funding (Co-PI’s: Noll & Trickett) is extending this study into middle adulthood where the effects of CSA on some of the leading health risks of this developmental period, such as cardiovascular disease, cancer, and obesity, are being examined. FGDS will also examine the changes in suspected biobehavioral mechanisms across development that may increase the risk for these adverse outcomes in this population. Such efforts will inform multiple types of clinical intervention as well as identify the optimal point in development to deliver such interventions. Graduate students are actively involved in conducting home visits, administering research protocols evaluating developmental outcomes in both adults and children, observational coding of parent-child interactions, as well as data entry and coding.
