Chronic pain is a multifaceted experience that involves physiological, psychological, and situational components.17 The experience of pain may vary widely among individuals; differences have been observed by gender,51 ethnicity,32,42 and even certain personality characteristics.41 The pain experience may also vary greatly among individuals reporting equally high levels of pain; while one may function poorly in several areas, another may experience minimal pain-related interference. Although sophisticated diagnostic tools (e.g., imaging studies) can assess anatomic contributions to pain, these are not reliable predictors of the extent to which pain affects functioning, disability, or quality of life.
