Abstract
Eighty-nine cancer pain patients participated in a study evaluating components of the Cognitive Adaptation Index on symptoms of posttraumatic stress disorder (PTSD). Positive correlations were found between optimism, mastery, and self-esteem. Inverse relationships with a PTSD symptom scale were also established. Multiple regression analyses for aggregate PTSD scores, avoidance/numbing, and arousal symptoms were each significant at p < 0.0001, intrusive symptoms at p < 0.020. Except for intrusive symptoms, self-esteem played a statistically significant mediating role for the influence of other variables. These results are discussed regarding their impact on PTSD, intervention strategies, and mental health of individuals experiencing stress.
