Dr Kia-Chong Chua is a methodologist in psychometrics and biostatistics, with an academic background in psychology and sociology, and a PhD in health service and population research.

Using advanced statistical methods (e.g., item response theory and structural equation modelling), he seeks to understand and mitigate the inherent impact of measurement issues on statistical analyses that investigate theoretical mechanisms, empirical profiles, and/or change over time.

As a methodologist co-Investigator in grant-funded projects, he contributes to shaping research direction and analysis design by discerning an interplay between substantive hypotheses, measurement issues, and statistical modelling approaches, in applied health research across fields like epidemiology, public health, medicine, psychiatry and psychology (click here for his Orcid research profile).
