類風濕性關節炎(Rheumatoid arthritis,RA)是一種慢性、進行性、發炎性的自體免疫疾病，以藥物為主要治療方法，目標以控制病情及維持日常功能為主，因此依循醫囑規則服藥是重要的。本研究目的在了解類風濕性關節炎病人的服藥遵從情形及探討影響因素。本研究為一描述相關研究，採立意取樣法，於98年3月至9月北部某醫學中心收取共150位類風濕性關節炎病人，研究結果顯示研究樣本有不錯的服藥遵從行為，年齡較大的病人會有較佳的服藥遵從行為(r=0.20:p=.01)；來自他人的影響(支持)越好，服藥遵從行為也會越好(α = 0.21, p = .01)。而服藥遵從行為不因病人的疾病及治療因素有顯著差異，感受療效、感受醫療現實亦沒有顯著影響服藥遵從行為。

Rheumatoid arthritis (RA) is a chronic, progressive, and inflammatory autoimmue disease. Medication is
the main treatment. The treatment goals are to control the disease progress and maintain the daily function.
Adherence with the medication treatment is very important. The purposes of this study are to explore the level
of medication compliance of patients with RA and to explore the influence factors. This is a descriptive
correlative study. Purposive sampling method was used and one hundred and fifty patients were recruited
from a medical center in northern Taiwan from March 2009 to September 2009. We found that older patients
showed better adherence (r =0.20, p = .01) than younger patients. The main predictor of adherence was the
“influence or support by others” (β=0.21, p = .01). The compliance did not differ by patients’ illness or
treatment factors, “perception of medication efficacy”, and “medical reality experience”.
