복합부위통증증후군 환자들의 MMPI 프로파일 및 심리적 특성 = MMPI Profiles and the Other Psychometric Characteristics of Patients with Complex Regional Pain Syndrome

다국어 초록 (Multilingual Abstract)

This study aimed at identifying the psychometric characteristics of patients with complex regional pain syndrome (CRPS). CRPS refers to neuropathic pain disorders developing as a disproportionate consequence of painful trauma or a nerve lesion affecting the limbs or a bone fracture, or as a consequence of a remote process like stroke, spinal cord injury or myocardial infarction. Although CRPS mechanism for the disease is still controversial, its onset and progress are widely known to be related to psychological factors. The subjects of this study included 102 patients suffering from CRPS. Their demographic data, responses to the illness behavior questionnaire (IBQ), multidimensional health locus of control scale (MHLC) and coping strategies questionnaire (CSQ), and their MMPI T scores were analyzed. Multivariate clustering analysis divided the patients' MMPI profiles into three homogeneous subgroups. Group I was characterized by 'conversion V' pattern with elevated Hs and Hy scores. Group II showed relatively normal profiles, but had more internal control than group III. Group III showed simultaneous increases in Hs-D-Hy scores and Pa-Pt-Sc scores. It also acquired higher scores than the other two subgroups in illness behavior characteristics, such as the hypochondriasis, disease conviction, affective inhibition and affective disturbance. Besides, with respect to a way to handle the pain, group III displayed more disastrous thinking than group II. In conclusion, an appropriate therapeutic approach that takes into account the characteristics of each sub group should be considered in the psychological treatment of patients suffering from CRPS.

국문 초록 (Abstract)

본 연구는 복합부위통증증후군 환자들의 심리적 특성을 살펴보고자 하였다. 복합부위통증증후군(Complex Regional Pain Syndrome: CRPS)은 사지의 외상이나 신경손상, 골절, 뇌졸중, 척수손상, 심근경색 등 다양한 인자에 의해 발생하는 신경병증성 통증이다. 복합부위통증증후군의 발병 기전에 대해서는 아직까지 논란이 있으나, 발병 및 경과에 있어 심리적인 요인이 많이 관여되어 있는 것으로 알려져 있다. 참여자는 102명의 복합부위통증증후군 환자들이었고, 이들의 인구통계학적 자료들, 질병행동질문지, 다차원 건강 통제척도, 통증대처전략질문지, MMPI T 점수결과가 분석되었다. 그 결과, 복합부위통증증후군 환자들의 MMPI 프로파일은 세 개의 하위 군집으로 구분되었다. 즉 군집 Ⅰ은 Hs와 Hy가 상승된 전환 V형태를 보였으며, 군집 Ⅱ는 비교적 정상프로파일을 보이는 집단으로 군집 Ⅲ에 비해 내적통제를 더 많이 나타냈다. 군집 Ⅲ은 신경증 세 척도(Hs, D, Hy)와 함께 정신증 세 척도(Pa, Pt, Sc)가 동시에 상승되어 있는 것으로 나타났다. 또한 질병행동 특성에 있어서 건강염려, 질병확신, 감정억제, 정서적 혼란감 척도에서 다른 하위집단에 비해 높은 점수를 보였으며, 대처방식에 있어서는 군집 Ⅱ에 비해 재앙적 사고가 높게 나타났다. 이러한 결과로 볼 때, 복합부위통증증후군 환자의 심리치료에 있어서 이들 하위유형군 간의 적절한 치료적 접근이 고려되어야 할 것으로 보이며, 일부 환자의 경우는 정신과적인 치료적 개입과 함께 통증대처전략을 수정시키는 훈련 프로그램이 치료에 큰 도움을 줄 수 있을 것으로 기대된다.
