This report presents the results of a study conducted to determine the reliability and validity of using 100-mm bipolar semantic scales to establish an ideal which can be used as a standard for subjectively evaluating facilities. Such an ideal standard would permit all facilities to be evaluated by looking at the difference between the profiles of ratings of existing and ideal facilities. Data were obtained through questionnaires administered to Air Force enlisted personnel, Army officers, and civilian Army office workers. Items rated using the 100-mm scales were existing and ideal dining facilities, existing and ideal Bachelor Officers Quarters BOQs, an ideal BOQ entrance, and an ideal wristwatch. Additional data were obtained through interviews. Results indicate that the 100-mm bipolar rating scales could be a viable evaluation tool with one qualification to provide any meaningful evaluation, the ideal scales must be paired with some dependent measure, such as existing scales. Without such a basis for comparison, there is very little differentiation between ideal ratings of various objects. The data indicate, in fact, that the 100-mm technique itself may influence a persons response to a greater extent than the type of object being rated does.
