Costa PT, Jr., McCrae RR. Hypochondriasis, neuroticism, and aging: When are somatic complaints unfounded? Am. Psychol. 1985;40(1):19-28.

Analyzes the relation between subjective and objective health to provide a framework for an evaluation of the view that medical complaints among the elderly are often unfounded. Naive realist, psychiatric-categorical, and dimensional models of somatic concern are compared, and it is argued that individuals differ along a continuum from persistent underreporting of symptoms to frank hypochondriasis. Data are presented showing that, even among psychiatrically normal individuals, the personality dimension of neuroticism is systematically related to the number of medical symptoms reported and that neuroticism- related complaints are best viewed as exaggerations of bodily concerns rather than as signs of organic disease. Psychometric data purporting to show that hypochondriasis increases in the elderly are confounded by real health changes with age, and evidence from longitudinal studies shows that increases in health complaints probably reflect veridical reports of changing health status. It is suggested that the stereotype of elderly men and women as hypochondriacs is unfounded.
