[Confirmatory analysis of the dimensional structure of the ODI, the SF-12 and the HADS-D scales in a sample of rehabilitation patients with musculoskeletal diseases].

| Abstract |
This study aimed at confirmatory testing the factorial structure of the established assessment instruments ODI, SF-12 and HADS-D by means of structural equation modeling in a sample of n=184 rehabilitation patients with musculo-skeletal diseases. According to local and global fit indices for each instrument an acceptable to good fit to the underlying theoretical model could be verified. For the ODI as well as for the HADS-D only single weak item-construct associations indicated shortcomings in the assumed model structure. For the SF-12 the constructs "physical health" and "mental health" could be validated after defining the additional first order factors "role - physical", "role - emotional" and "well-being", respectively. In general, the study findings proved the factorial validity of the instruments. Additionally, specific measurement properties on item and structural level could be identified which might enhance the understanding of construct definitions in rehabilitation patients with musculoskeletal diseases.
