OBJECTIVE: Given the prevalence and complexity of @entity1118 , there is a need for measures of disability that (a) provide comprehensive, useful clinical information with regard to @entity1 functioning, and (b) do so as briefly as possible to minimize respondent burden. The primary objective of this study was to reduce the length of a well-known, highly detailed measure of disability, the 136-item @entity3355 ( @entity3355 ), and develop a psychometrically sound short form for use in @entity1118 ( @entity3355 for @entity1118 , @entity2723 ). METHOD: A 2-parameter logistic item response theory model was used to develop the @entity2723 in a sample of adults presenting for treatment at an interdisciplinary rehabilitation program (N = 723). Items were assessed for inclusion at the subscale level; poorly contributing items were removed sequentially, and model fit was evaluated at each step until adequate fit was achieved. Finally, linear regressions examined the variance accounted for by the @entity2723 in relation to the full-length @entity3355 in measures of @entity1 functioning. RESULTS: The @entity2723 contains 42 items that yield 7 subscale scores and 2 summary dimension scores, Physical and Psychosocial disability. Acceptable reliability and evidence of convergent and divergent validity were demonstrated for each component. The @entity2723 accounted for a similar amount of the variance in measures of @entity308 , @entity158 -related @entity148 , @entity158 acceptance, classes of prescribed analgesics, and @entity158 as the full-length @entity3355 . CONCLUSIONS: The @entity2723 appears to provide robust clinical information with little loss of association with other key aspects of functioning, while substantially lowering response burden.
