I am a Senior Lecturer at the Discipline of Psychology, Faculty of Health. My research over the last 20 years, and that which I plan to continue in the future, focuses on social and individual influences on psychological health across the adult lifespan. In addressing this topic, my work utilizes multiple methodologies, and is informed by an interdisciplinary theoretical framework. Drawing from the World Health Organization’s definition of mental health and the work of a number of researchers, such as Carol Ryff’s extensive work, I conceptualize psychological health as a state of well-being in which individuals realize their potentials and can cope successfully with the normal stresses of life. Within this broad framework, I address three questions. First, what are the psychosocial determinants of psychological health? That is, what personality and social factors predict individuals’ psychological health status? Second, do the effects of psychosocial determinants of psychological health vary across age groups? Third, how do adults of different ages maintain an optimal level of psychological health in the face of stress?
