Positive ego and coping functions in chronic pain and depressed patients.

Three groups of elderly subjects (chronic pain patients, patients with major depression, and healthy individuals) were administered measures of self-esteem, ego defense mechanisms, and coping style to examine how these personality components are affected by illness. Ego defense mechanisms and self-esteem for all three groups were not found to be different and were positive except for depressed patients, who used greater levels of projection and demonstrated lower levels of self-esteem. Each subject group utilized equally problem-focused and emotion-focused coping styles. These findings from a preliminary study are consistent with previous research demonstrating stability of personality throughout the life span, and suggest that the psychological functioning of older individuals with chronic pain syndromes or depression remains positive and resilient.
