Chronic pain patients (16) rated their mood, anxiety level, pain, muscle tension and reclining time daily over a period of about 6 wk. Correlations were calculated for each combination of variables for each individual patient. A good deal of variability between patients was indicated. The majority of patients did have significant correlations for pain vs. mood, pain vs. anxiety, pain vs. reclining time, anxiety vs. muscle tension, anxiety vs. mood and reclining time vs. mood. However, the size of the correlations was sometimes small and some patients even occasionally had correlations in the opposite direction of that predicted. Psychological variables are evidently related to the experience of chronic pain, but the size of the relationship may be smaller than previously thought. The high degree of individual variability needs to be stressed.
