Objective: Fibromylagia (FM) is a rheumatic disorder characterized by widespread bodily pain, tenderness, and fatigue. It has a major impact on the quality of life including the quality of marital life. The objectives of this study were to assess the quality of marital life in patients with FM in Korea and to identify the correlation of the quality of marital life with disease severity. Methods: Subjects were the patient group, composed of 50 married patients with FM, and a comparison group composed of 50 healthy married adults with similar demographic characteristics. The quality of marital life was measured using the Korean-Marital Satisfaction Inventory (K-MSI). The K-MSI consists of two valid scales, one global affective scale, and eleven additional scales measuring specific dimensions of relationship distress. The clinical parameters were assessed by Korean Fibromyalgia Impact Questionnaire (KFIQ) and tender point, respectively from 50 patients with FM. Results: Of the 50 subjects, 48 (96%) were women with mean (±SD) age of 52.6(±8.8) years. The mean (±SD) duration of disease was 25.7 (±19.8) months. The mean (±SD) scores of KFIQ and tender point count were 52.9 (±14.9) and 13.1 (±1.6), respectively. The T-score of most scales of K-MSI of FM patients were higher than that of healthy controls (p＜0.01). The scores of KFIQ were positively correlated with the eight scales of K-MSI and negativelycorrelated with one scale (Role orientation) of K-MSI. The tender point count was positively correlated with only one of scale (Conflict with in-law) of K-MSI. Conclusion: The results suggest that the quality of marital life in Korean patients of FM is lower than healthy subjects. In a simple correlation analysis, KFIQ was a meaningful variable correlated with the quality of marital life.
