Entwicklung einer Kurzversion des Spinal Function Sort (M-SFS): Ein Mixed-Method-Ansatz ,

Abstract

▼Background: The Spinal Function Sort (SFS) is an illustrated questionnaire including 50 questions for assessing the perceived functional ability regarding activities with negative impact on the spinal column. The SFS developed by the Leonard Matheson in 1989 is used within the scope of the assessment of functional ability. Previous studies recommend a shortened and revised version. Objective: To develop a modified version of the Spinal Function Sort measuring perceived functional ability for work-related activities in patients with chronic low back pain. Methods: A mixed method design consisting of methods (M) was performed. In interviews, participants were asked which postures in daily life were related to their back pain and how often they perform the activities of the 50 SFS items in one week (M1). Quantitative analysis of previously obtained SFS data consisted of measuring floor and ceiling effect, internal consistency with all and half of the items, item-to-total correlations, principal component analysis (PCA) and Rasch analysis (M2). Experts rated the SFS items based on relevance (M3). Based on the results of M a total score for each item of the SFS was calculated, and merged with the results of the interviews (M4). Results: From interviews with 17 participants, eight new items emerged (M 1). Quantitative aDieses Dokument wurde zum persönlichen Gebrauch heruntergeladen.
