* Items listed in the order they were deleted; ± modifications suggested when subscales analysed separately. £ Same results if delete item 19 first followed by items 3 and 8. Original adaptive subscale 13 items = Cognitive avoidance (11,17,26,27); Fighting spirit (2,10,18,23) and Fatalism (1,3,8,19,24). Original maladaptive subscale 16 items= Helplessness-hopelessness (4,6,12,14,15,16,20,21) and Anxious preoccupation (5,7,9,13,22,25,28,29).
