Abstract

ABSTRACT Drawing on a carefully controlled sample of 52 women with a history of breast carcinoma and 34 healthy controls, this prospective study examined empirical associations between psychological factors and the progression of neoplastic disorders over a follow-up period averaging 624 days Psychological variables were psychometrically assessed by self-report measures A multiple regression analysis which controlled for disease stage at original diagnosis, age, total length of disease course, hematological factors, and blood chemistries measured at study onset showed neoplastic spread to be associated with a repressive personality style, reduced expression of negative affect, helplessness-hopelessness, chronic stress, and comforting daydreaming The identified model of medical and psychological variables accounted for 56% of the observed variance A psychobiological model of brain-body deregulation provided the best account of the observed associations between psychological functioning and the progression of disease Future research is necessary to examine the role which psychological functioning may exert upon health-relevant behaviors that might blunt the benefits of professional health care
