Disability and rehabilitation
-
Purpose: The aim of this study was to evaluate the psychometric properties of the Functional Disability Inventory for assessing pain-related disability in a community sample of children and adolescents. Materials and methods: Five hundred and sixty-one schoolchildren (aged 8-18 years) completed the Functional Disability Inventory. They were also administered measures assessing anxiety sensitivity, internalizing pain coping behaviors, social support seeking, and positive self-statements. ⋯ However, its psychometric properties have not been studied in a community sample. This study shows new and important findings demonstrating that the FDI provides reliable and valid scores when used to assess pain-related disability in a community sample of schoolchildren. These findings support the use of the FDI as a measure of the benefits of community-based pain treatments or the benefits of disability prevention programs over time.
