Relationships between self-efficacy on health behavior and patient's assessment of rheumatoid arthritis conditions / 日本プライマリ・ケア連合学会誌

ABSTRACT

<b>Objective</b> The purpose of this study was to examine the relationships between levels of self-efficacy on health behavior of outpatients with rheumatoid arthritis (RA) and patient's assessment of RA conditions.<br><b>Methods</b> A cross-sectional study was performed using a self-administered anonymous questionnaire between October and December 2010 on 406 RA outpatients who consecutively visited 3 urban hospitals in Japan. The following variables were investigated ; (1) the scale of self-efficacy on health behavior in chronic disease patients (CD-SES), which has 2 subscales active coping behavior with disease (14 items) and controllability for health (10 items). (2) The demographic data ; age, gender, duration of disease, treatment. (3) patient's assessment of RA conditions painful joint count, swollen joint count, serum C reactive protein (CRP), patient estimate of global status (PGS) which was measured on a 100-mm visual analogue scale (0=best score), functional disability according to Japanese version of modified Health Assessment Questionnaire.<br><b>Results</b> CD-SES data were obtained from 191 patients. 80<b>%</b> was female with mean age 64.4 yr. Total CD-SES scores significantly correlated with age, PGS and functional disability. The scores of active coping behavior with disease correlated with age, and the scores of controllability for health correlated with PGS. The other variables such as painful joint counts, swollen joint counts, and serum CRP showed no relationship with the scores of self-efficacy.<br><b>Conclusion</b> Self-efficacy on health behavior of RA patients related to PGS and functional disability. The longitudinal study is necessary to ascertain whether the psychological support enhances self-efficacy, and affects clinically important outcome measures such as PGS.
