Why the study?
Morning stiffness significantly affects functional ability, quality of life, and employment status, creating a need for a valid, reliable tool to comprehensively assess it.
Is the newly developed Morning Stiffness Assessment Scale valid and reliable in patients with rheumatoid arthritis?
Is the newly developed Morning Stiffness Assessment Scale valid and reliable in patients with rheumatoid arthritis?
The newly developed 10-item Morning Stiffness Assessment Scale provides a valid, reliable, simple, and brief tool for comprehensively evaluating morning stiffness in rheumatoid arthritis patients.
May offer a brief RA morning stiffness measure; hypothesis-generating and requires further validation before clinical use.
Morning stiffness is known to exert a significant impact on functional ability, quality of life, and employment status. There is an increasing need for a valid, reliable tool to comprehensively assess morning stiffness. The purpose of this study was to develop and verify a Morning Stiffness Assessment Scale. Items were developed on the basis of a framework of the conceptual attributes of morning stiffness. Validity and reliability tests were conducted on the devised scale. Eighty-five patients with rheumatoid arthritis were included to verify the devised scale. A 10-item Morning Stiffness Assessment Scale was developed. Its content and construct validities were well supported. The scale was found to have good reliability. The devised scale is simple and brief, but it provides a more comprehensive means of evaluation for morning stiffness. We believe this scale offers a clinically useful means of properly assessing morning stiffness and has potential utility for evaluating the effects of morning stiffness treatments.
