The present study was designed to test the chronic patients' construing of pain by means of the Rep Grid technique from Personal Construct Psychology. The subjects were 40 chronic pain patients. The instruments were the 12 constructs × 12 elements Rep Grid, Pain Questionnaire, SF McGill Pain Questionnaire, and Korean CES-D. The data were analysed by the INGRID Program. The main results were as follows: First, for chronic pain patients the pain was superordinate construct. Second, for chronic pain patients, self now with pain offered the more implications than other elements. Third, chronic pain patients had difficulty in expressing or inhibited anger, depression, and sensitivity toward themselves and others. Finally, the results were discussed with reference to the literature and suggestions are made for future research areas.
