Background: Knowledge regarding the possible influence of self-efficacy, pain intensity and disease duration on hand functional disability could promote new intervention strategies for activities of daily living (ADLs) in patients with rheumatic disease (RD). These approaches could prevent the health problems and socioeconomic costs associated with these diseases.


Objective: The aims of this study were to evaluate if there are differences between the levels of perceived self-efficacy, pain intensity and disease duration among people with RD and non-RD diseases, and to analyze if hand functional disability in ADLs is related to self-efficacy, pain intensity and disease duration in a sample of patients with RD.


Methods: A multicenter, observational, cross-sectional study was conducted on a total sample of 335 participants over 50 years old (176 patients with RD and 159 individuals with non-RD). The Duruoz Hand Index, the General Perceived Self-Efficacy Scale, the Rheumatic Diseases Self-Efficacy Scale (RDS-ES), the Visual Analog Scale (VAS), and the mean time of evolution in years of the disease (disease duration) were used to analyze the possible relationships surrounding hand functional disability in ADLs.


Results: The comparison analysis showed significant differences between the RD/non-RD sample for the General Perceived Self-Efficacy Scale, RDS-ES, and VAS scores (p < .001). The multiple regression results showed that age, General Perceived Self-Efficacy Scale scores, RDS-ES scores, VAS scores, and disease duration (or a combination of some of them) explained the variability of hand functional disability in almost 68% of kitchen tasks, 44% of dressing tasks, 46% of hygiene and other tasks, and 47% of office tasks.


Discussion: Our study shows that general and domain-specific self-efficacy, pain intensity, and disease duration are predictors of the dimensions of hand functional disability in patients with RD. Early evaluation of these components with an interdisciplinary approach would help to manage hand disability properly.
