Psychometric Properties of the Swedish Rheumatic Disease Empowerment Scale, SWE-RES-23

• Empowerment is a central concept in a patient-focused rheumatology care. WHO describes empowerment as a process in which the person receives more control over decisions and actions that affect the own life and health. Today there is no Swedish empowerment instrument for rheumatic diseases created or transl[...]The already existing questionnaire, Swedish Diabetes Empowerment Scale (SWE-DES-23), was adapted for use in patients with rheumatic diseases by exchanging the word diabetes with rheumatic disease in all the questions. No items were added or removed. The adapted questionnaire was called SWE-RES-23. In 2009, 260 patients with rheumatic diseases from a rheumatology unit in the southwest of Sweden completed the questionnaire.In order to establish discriminant validity, a question about self-perceived health from SF-36 was used in addition to SWE-RES-23.Construct validity was tested by using exploratory factor analysis. In order to determine unidimensionality of the empowerment subscales, inter-item correlations were calculated. Internal consistency reliability was tested by the use of the Cronbach-α coefficient.The exploratory factor analysis resulted in five factors (empowerment subscales) with Eigenvalues >1 explaining 64.1% of the variance. The five empowerment subscales were: Goal achievement and overcoming barriers to goal achievement, Self-awareness, Managing stress, Assessing dissatisfaction and readiness to change, and Support for caring. The Cronbach-α values ranged from 0.59 to 0.91 and for the total score 0.92. All inter-item correlations were significant. Patients with very good and good self-reported health scored significantly higher on three empowerment subscales (Goal achievement, Self-awareness and Managing stress). The same patterns were seen in the other two empowerment subscales (Readiness to change and Support for change), but did not reach significance.The SWE-RES-23 was a first step in developing a questionnaire for assessment of empowerment of patients with rheumatic diseases. The questionnaire possesses acceptable validity and reliability. To fully validate the SWE-RES-23 further studies are needed, but the instrument is even now possible to use in empowerment education programmes for patients with rheumatic diseases.
