Abstract
Thirty-one parents of children suffering from fatal illnesses were studied psychologically. Urinary 17-hydroxycorticosteroid (17-OHCS) levels were measured concurrently. Throughout the extended crisis, these parents had characteristic mean 17-OHCS excretion rates along the continuum from high to low excretion. The hypothesis was tested that the more effectively a parent defends against the threat of loss, the lower will be his mean 17-OHCS excretion rate. Criteria for “effective” defense were derived. Each parent was interviewed, and a prediction of the mean 17-OHCS excretion rate was made according to the criteria and independently of the endocrine data. The methods of interviewing and predicting are briefly described. The results indicated significant correlation between the predictions and the mean 17-OHCS excretion rates. The 17-OHCS and psychologic data of a representative high and a representative low excretor are presented. The authors suggest that these chronic differences between individuals in mean 17-OHCS excretion rates and effectiveness of defense are importantly related aspects of the individual's response to threat.
