Biography
My primary interest is the associations between mental disorders and antisocial behavior, as well as assessment issues. I also collaborate with colleagues in different disciplines (e.g., psychology, psychiatry, public health, nursing, neurology) to examine the changes in human behavior (e.g., antisocial behavior, cognition, mental health) over time. I am familiar with a wide range of statistical techniques, including multi-level analysis, structural equation modeling, and item response modeling.

Longitudinal Trajectories of Personality Disorders: A Growth Mixture Modeling Analysis
Author(s): Siny Tsang
Among clinical and community samples, personality disorders (PDs) have been consistently reported to have negative effects throughout the lifespan. Although longitudinal studies have reported a general decline in PD symptoms, it is unclear whether there are subgroups of individuals with different PD trajectories from early adolescence to adulthood. This study aimed to examine this question in a large representative community sample and identify early childhood predictors of these varying trajectories. Longitudinal data collected across 20 years from participants in the Children in the Community (CIC) Study, a representative nonclinical cohort, were used. Trajectories of each PD cluster across four waves of assessments were estimated using growth mixture mode... view more»
