Divided the Minnesota Multiphasic Personality Inventory Pd scale into obvious (O), neutral (N), and subtle (S) subscales. Using college students results were: Pd-O scores were the most powerful predictor of criterion; Pd-S scores made a smaller but unique contribution; and Pd-N scores made no contribution not already in Pd-O criterion…

Obvious items were good predictors of all criteria; neutral items overlapped considerably with obvious items; and subtle items generally did not contribute uniquely to the prediction of any of the concurrent measures of depression. (Author)

THE PROBLEM OF THIS RESEARCH WAS TO DEVELOP AND VALIDATE A K SCALE FOR A MOTIVATIONAL TEST BATTERY. APPROXIMATELY 4,200 11TH GRADE, MICHIGAN PUBLIC HIGH SCHOOL STUDENTS COMPRISED THE STUDY. PROTOCOLS OF ABOUT 300 IDENTIFIED OVER- AND UNDERACHIEVERS WERE USED. AN ANALYSIS WAS CONSTRUCTED TO IDENTIFY ITEMS ON WHICH UNDERACHIEVERS SCORE AS…
