The Family System Functioning (FSF) scale is a new instrument for measuring dimensions of the intrafamilial environment thought to be important in recovery from major psychiatric illness. Modest statistical correlations were obtained when FSF ratings of laboratory-based family interactions were compared with researcher-guided therapist ratings of FSF based upon the family's behavior in family therapy sessions during the subsequent month. The data from these two settings provide support for the validity of some of the scales. Because of the modest size of the correlations, however, behavior in the laboratory setting may not always be an accurate indicator of how the family will behave in the early weeks of family therapy.  相似文献

Within our present health care system, there is a growing movement that argues that our perceptions of health and illness are in need of change. This change includes redefining what we mean by health in terms of the whole person—the emotional, social, and spiritual dimensions of our being, as well as the physical. An increasing number of health professionals and social scientists believe our concepts of health and illness must consider all these aspects of life. It is believed that the quality of life may be enhanced by such perceptions of health, which include social and spiritual factors. Using data from the 1985 Akron Area Survey—The Subjective Quality of Life in the Akron Area—this study explores the effects of spiritual well-being and emotional well-being on health satisfaction. Results indicate that emotional and spiritual factors do significantly contribute to the subjective evaluation of health, especially for individuals who are physically limited.An earlier draft of this paper was presented at the joint session of the Association for the Sociology of Religion and the American Sociological Association, August 20, 1986. The author would like to thank Margaret Poloma, Ph.D., The University of Akron, and Mark Tausig, Ph.D., The University of Akron, for their helpful comments.  相似文献

Orientation discrimination and cortical function in the human newborn   总被引:1,自引:0,他引:1  
A Slater  V Morison  M Somers 《Perception》1988,17(5):597-602
There is some controversy concerning whether or not the visual abilities of the newborn are mediated entirely through subcortical pathways or whether the visual cortex is functioning at birth. A critical test of cortical functioning is discrimination of orientation: orientation-selective neurons are found in the visual cortex but not in subcortical parts of the visual system. An experiment is described in which newborn infants were habituated to a square-wave grating oriented 45 degrees from vertical. After habituation, significant preferences for the novel, mirror-image, grating were found, a result which argues for some degree of visual cortical functioning at birth.  相似文献
