Assessment of functioning and disability in patients with low back pain - the low back pain assessment tool. Part 1: development.

This study presents the process used to develop the LBP assessment tool, which is the first tool to address all ICF components and integrate biopsychosocial perspectives provided by patients and health professionals in the same tool. Initial evaluation of content validity showed adequate reflection of the construct "functioning and disability". Further work on the way will evaluate comprehensiveness, acceptability, and degree of implementation of the LBP assessment tool to strengthen its use for clinical practice.Implications for RehabilitationA biopsychosocial and patients-centred approach is a strong foundation for identifying the many relevant aspects related to low back pain (LBP).Responding to a lack of tools to support a biopsychosocial and patients-centred approach the LBP assessment tool was developed using a robust, multi-step process with involvement of patients and health professionals.The LBP assessment tool is a strong candidate for a user-friendly tool to facilitate use of the International Classification of Functioning, Disability and Health in routine clinical practice.
