This study was based upon the theoretical rationale that although we make many assumptions about the nature of health, based on research of disease, relatively little empirical evidence of the characteristics of healthy people can be found. In the literature, prevailing ideas about health had been organized into four models–clinical, role performance, adaptation, and eudaimonistic. These models are considered to proceed hierarchically in the direction of greater complexity and comprehensiveness, with each model subsuming the characteristics of the lesser models. Health in the eudaimonistic or self-actualization model measured by the Personality Orientation Inventory (POI) was the major focus of the study. It was hypothesized that moderation and balance, manifested by mid-range scores on the above characteristics, would be correlates of eudaimonistic health. Cognitive style was measured with the Group Embedded Figures Test (GEFT) and interpersonal need was measured with the Fundamental Interpersonal Relations Orientation-Behavior (FIRO-B). A heterogeneous population of nonclinical adults was sought and volunteers were recruited.The sample consisted of 163 upper-middle-class suburban subjects. The POI chosen to measure health, the GEFT, and the FIRO-B, plus a Personal Information Sheet, were administered to groups of approximately 20. This study did not yield support for the hypotheses. Although not statistically significant, moderation in both cognitive style and interpersonal needs were related to eudaimonistic health in the predicted direction. There is a continuing need to investigate the characteristics of healthy people. Future studies might attempt to control for sex since the patterns were distinctly different when analyzed by sex. Healthy adults in the eudaimonistic, self-actualizing model are described by the findings as busy, effective, loved, loving, and respected, among other traits too numerous to mention. With the development of multivariate, process-oriented instruments, empirical investigation of moderation and balance might be more fruitful.
