The relationship between dispositional optimism, dispositional pessimism, repressive coping and trait anxiety

The purpose of this study was to investigate the relationship between dispositional optimism, dispositional pessimism, repressive coping and trait anxiety. The Marlowe-Crowne scale (MC) and the Bendig version of the Taylor Manifest Anxiety Scale (MAS) were used to select repressor and control groups (N=143, aged between 18 and 47 years), who subsequently completed a measure of dispositional optimism, the Life Orientation Test (LOT), which consists of two sets of items: optimism and pessimism. Repressors (high MC, low MAS) reported significantly lower pessimism than all other participants. When the pessimism scale was divided into high and low categories, there were significantly more repressors in the low pessimism group than the other low trait anxiety group, low anxious (low MC, low MAS). However, for the optimism scale the opposite pattern of results was found, with significantly more low anxious in the high optimism group than repressors. These results support the assertion that the pessimism and optimism scales of the LOT are not the same construct and should be measured separately.
