The purpose of this study was to examine the relationship between task complexity and decision-making consistency using a normative decision model. The Decision Analytic Questionnaire (DAQ), an instrument designed to measure nurses' decision making under increasingly uncertain and complex conditions, was administered to a stratified random sample of 101 paid volunteer medical-surgical nurses drawn from three public teaching hospitals. Probit analysis was used to construct a profile of the decision maker whose decisions coincided with those of the model. Results indicated that nurses made clinical decisions that coincided with those recommended by a normative decision model but that agreement diminished as task complexity increased (p less than .005). The results also indicated that consistency was task specific, that predictive variables were a function of decision task and that more predictor variables were needed to explain consistency as task complexity increased.

The authors examined the effects of materials for educating patients about treatment options for breast cancer on knowledge about the disease, preferences for alternative treatments, and how changes in knowledge and preferences were related. Eighty-two undergraduate students acted as advisors to a hypothetical patient. They completed a knowledge test and rated their preferences for three options--breast-sparing surgery with radiation, mastectomy followed by reconstructive surgery, and mastectomy followed by use of a breast prosthesis--before and after viewing a videotape or a booklet version of the educational materials. Both formats increased knowledge scores. Treatment preferences were not affected by reading the booklet, but viewing the videotape resulted in a preference shift toward breast-sparing surgery. This media difference may be due to features of the video that were not reproduced in the booklet, such as interviews with other patients. Knowledge gains were uncorrelated with preference changes.
