Validity and reliability of the Arabic version of the Self-Efficacy for Managing Chronic Disease scale in rheumatoid arthritis patients

Abstract

Background and objectives Rheumatoid arthritis (RA) is an autoimmune inflammatory condition that causing disability and affection of patient’s quality of life (QoL). Self-efficacy investigation helps us to detect the requirements of chronically affected patients and evaluation of self-care management programs. The aim of our study was to test validity and reliability of Self-Efficacy for Managing Chronic Disease (SEMCD-Arabic) in RA patients. Method This study included 248 RA patients, carried out at Rheumatology and Rehabilitation Department. The SEMCD-Arabic Validity was assessed by correlating the SEMCD-Arabic scale with the validated Arabic version of the modified Health Assessment Questionnaire HAQ (MHAQ), the Arabic version of the Multidimensional Assessment of Fatigue (MAF) scale, and the Arabic version of Short Form 36 version 2 for quality of life (SF QoL). Internal consistency, test–retest reliability was assessed. Results Convergent validity was confirmed by a positive correlation between (physical, mental) component of SF QoL and SEMCD-Arabic (r = 0.918, r = 0.925) respectively, and negative correlation between MAF and SEMCD-Arabic (r = − 0.657) and MHAQ with SEMCD-Arabic (r = − 0.595). Discriminant validity confirmed by a significant negative correlation between visual analogue scale (VAS) for pain, disease activity scale (DAS28), Morning stiffness, patient health, physician health, age, duration, and SEMCD-Arabic (r = − 0.1–0.7) (P < 0.001). Test–retest reliability was estimated which revealed a high interclass correlation coefficient (ICC = 0.87–0.997) indicating excellent agreement and internal consistency is acceptable as the Cronbach’s alpha value (0.660 to 0.78). Conclusion The SEMCD-Arabic questionnaire can be used as a valid and reliable measure for assessment of patient’s self-efficacy in RA. Key Points• The SEMCD-Arabic questionnaire has a statistically significant validity in correlation with different clinical manifestations MHAQ, SF QoL, and MAF.• The Arabic SEMCD is highly reliable with a Cronbach’s alpha of 0.660 to 0.78.

Psychometric properties of the self-efficacy scale for chronic disease management (SEMCD-S) in older Colombian adults

“…There were no differences in the self-efficacy for the management of chronic disease of the participants analyzed in this study, except when this construct was compared in relation to academic level, in which 52% of the sample completed elementary school and 24% completed secondary school, see Table 4 , which coincides with the research conducted in Chile where a relationship was found between educational level and adherence to treatment in patients with chronic diseases and stress [ 32 ], while educational schooling is not related to self-efficacy [ 19 , 21 , 24 ].…”

“…In contrast to this characteristic, in the rest of the sociodemographic aspects the means of the latent factors were similar, different from studies conducted in Europe and Asia where age and gender marked a significant difference in self-efficacy against the disease and quality of life of patients. [ 19 , 24 ]; in this case, the results suggest that people who completed high school or university studies showed higher self-efficacy than those who reached primary school levels, which implies a statistically significant difference of low magnitude (Dif.=0.38, z = 2.33, p = .020, Cohen’s d = 0.32).…”

“…The 6-item SEMCD scale has been psychometrically evaluated in non-US contexts such as Brazil [ 10 ], Germany [ 11 ], Iran [ 12 ], South Korea [ 13 ], Portugal [ 14 ], Turkey [ 15 ], Sweden [ 16 ], France [ 17 ], Saudi Arabia [ 18 ] and Canada [ 19 ].…”
