Key result
Persian RA-SMBS shows excellent internal consistency with ~0.92 alpha and a robust four-factor structure.
Why the study?
Self-management behaviors are critical in rheumatoid arthritis, requiring a dedicated and comprehensive instrument with strong validity and reliability for their assessment.
Cross-Sectional (n=334)
Yes
The Persian version of the Rheumatoid Arthritis Self-Management Behaviors Scale (RA-SMBS) is a reliable and valid tool for assessing self-management behaviors in Iranian patients with rheumatoid arthritis.
May enable self-management assessment in Persian-speaking RA patients; leaves open effects on adherence or outcomes.
OBJECTIVE: Self-management behaviors play a critical role in controlling disease complications, improving treatment outcomes, and enhancing quality of life for Rheumatoid arthritis (RA) patients, a dedicated and comprehensive instrument with demonstrably strong validity and reliability is crucial for their assessment. To address this need, the present study undertook the translation and validation of the Persian version of the "Self-Management Behaviors Questionnaire" specifically for RA patients. Employing a cross-sectional research design, the study involved 334 participants from four Iranian cities. Following the meticulous translation of the original RA-SMBS instrument into Persian, a comprehensive evaluation of its psychometric properties was conducted using the established COSMIN criteria. RESULTS: The exploratory factor analysis (EFA) revealed statistically significant factor loadings ranging from 0.62 to 0.89 for all 23 items, indicating a robust underlying factor structure. Furthermore, the instrument demonstrated excellent internal consistency, with a Cronbach's alpha coefficient of 0.92 for the entire scale. These findings collectively establish the Persian version of the Rheumatoid Arthritis Self-Management Behaviors Scale (RA-SMBS) as a reliable and valid tool. Consequently, healthcare administrators can confidently utilize this questionnaire to assess self-management behaviors in their RA patient population. This information can then be leveraged to develop and implement targeted programs and strategies aimed at enhancing self-management skills among individuals living with rheumatoid arthritis.

Rezaeian et al. (2025) conducted a cross-sectional in Rheumatoid arthritis (n=334). Persian version of the Rheumatoid Arthritis Self-Management Behaviors Scale (RA-SMBS) was evaluated on Psychometric properties (internal consistency and construct validity). The Persian version of the Rheumatoid Arthritis Self-Management Behaviors Scale demonstrated excellent internal consistency with a Cronbach's alpha of 0.92 and a robust four-factor structure.
