Aiken's research interests include both quantitative methods and health psychology. In quantitative methods she is interested in continuous variable interactions in multiple regression. She is also interested in the use of design approaches and mediational analysis to untangle the effects of individual components in multi-component interventions. In health psychology, Aiken is interested in adoption of health protective behaviors across the life span, particularly among women, both from the perspectives of psychosocial models of the putative determinants of health protective behavior and from the perspective of interventions to increase health protective behavior. She has studied mammography screening, condom use, sun protection, and the adoption of hormone replacement therapy. Health psychology research projects: Determinants of perceived susceptibility to diseases of aging, post-decisional processes following the adoption of hormone replacement therapy, strategies for piercing perceptions of invulnerability to disease, understanding of osteoporosis risk and osteoporosis protective health practices among young women, determinants of use of sun protection against skin cancer among young adult males. Quantitative psychology research projects: Analysis of coarsely categorized outcome variables in multiple regression
