Cognitive adaptation theory as a means to PTSD reduction amongst cancer pain patients

Eighty nine patients treated for cancer-induced pain participated in an investigation of the impact of components of the Cognitive Adaptation Index (Taylor, 1983) on symptoms of PTSD. Measurements were taken of optimism, mastery, and self-esteem, which have been identified as being heightened when attempting to minimize stress. Positive correlations were found between these measures. Inverse relationships with a PTSD symptom scale were also established. Multiple regression analyses for aggregate PTSD scores and specific intrusive, avoidance/numbing, and arousal symptoms yielded coefficients of determination significantly different from zero. For each analysis, except for intrusive symptoms, self-esteem played a statistically significant predictive role, mediating the influence of the other independent variables. These results are discussed in terms of their impact on manifestations of this illness, possible intervention strategies, and the overall mental health of individuals in stressful situations.;Key words: Cognitive adaptation, Optimism, Mastery, Self-esteem, Cancer, Cancer pain, Posttraumatic stress disorder, PTSD...
