Note. The numbers in parentheses in the first column reflect the number of items on each RCS followed by the number of items on the corresponding CS. RCS = Restructured Clinical Scale; CS = Clinical Scale; PK = Keane PTSD; MMPI-2 = Minnesota Multiphasic Personality Inventory-2; Corr = correlation; D = demoralization.
