Curriculum Vitae


Negative social interaction and social support among older adults; health behaviors among older adults; applied statistical analysis (especially applications of structural equation modeling, longitudinal research design, and analysis), and receiving care among physically impaired older adults.


Dr. Newsom has served as a principal or co-investigator for studies funded by National Institutes of Health Research that focus on social relationships, health behavior, and caregiving . Current and recent projects include an investigation of changes in health behaviors in mid to late life among those with chronic disease as well as a national longitudinal study of the mental and physical health consequences of negative social exchanges. He recently completed editing (with Richard N,. Jones and Scott M. Hofer) a book on data analysis of longitudinal studies on aging.
