Sammanfattning
Chronic or recurrent pain is a common experience in children and adolescents. One
questionnaire that is frequently used
to assess pain-related disability is the Functional Disability Inventory (FDI). The aim of this study
was to evaluate the
psychometric properties of the Swedish version of the FDI. The patient group consisted of 30
patients, 8 - 17 years old. The
comparison group consisted of 78 pupils, 8 - 17 years old. Reliability was assessed using Cronbach
’ s alpha and intraclass
correlation (ICC). Validity was assessed in terms of construct validity and face validity. To assess
construct validity, Spearman
’ s rho was used. Internal consistency reliability was high, with Cronbach ’ s a 0.90. Similarly, test -
retest reliability was
good, with an ICC of 0.90 (95% confi dence interval 0.78 - 0.95). Concerning interrater reliability, the
result was good, with
an ICC of 0.67. Construct validity correlations, assessed using Spearman ’ s rho, were signifi cant.
Most participants (85.7%)
did not report any areas in their everyday lives where they experienced any disabilities not covered
in the FDI, indicating
acceptable face validity. In this context and used in this population, the results indicate that the FDI
is a reliable and valid
questionnaire for assessing pain-related disability in children and adolescents.
