The relationship of arthritis self-efficacy to daily pain, daily mood, and daily pain coping in rheumatoid arthritis patients.

This SLR  aimed to identify studies investigating measurement properties of PROMs for spondyloarthritis, and to evaluate their methodological quality and level of evidence relating to the measurement properties of PROMs. 

This study examined psychometric properties of the 8-item English version of the Arthritis Self-Efficacy Scale (ASES-8) and differences in ASES-8 scores across sample subgroups.

The original ASES was developed to measure patients’ arthritis-specific self-efficacy, or patients’ beliefs that they could perform specific tasks or behaviors to cope with the consequences of arthritis. It remains the most widely used arthritis-specific measure.

It  measures three SM constructs: pain self-efficacy, function self-efficacy and other symptoms self-efficacy. 8-item version includes two items from the pain subscale, four items from the other symptoms subscale, and two new items that relate to preventing pain and fatigue from interfering with daily activities.  

The ASES refers throughout to arthritis. The symptoms that AS patients experience are usually related to the spine and less frequently to peripheral joints, raising concerns that AS patients may not feel that assessing only arthritis encompasses their experience of disease. Therefore direct use of the ASES in an AS population is not feasible. In view of this, a rephrase of the ASES to specifically assess the impact of AS was conducted.

The ASES-AS is based on the 8-item ASES with minor alterations in phraseology. 

The score is the mean of the eight items. At least six items must be completed to obtain a score.
