[Diagnostics of work motivation (DIAMO): optimization and construct validity].
METHODS
Faced with increasing cost pressure of the social insurance system the carriers of rehabilitation programs focus on the efficacy of their measures. The diagnostic instrument for work motivation (DIAMO) has been developed to assess the influence of job-related motivation on the rehabilitation outcome.


METHODS
The inner structure of the instrument was validated and optimized in a cohort of medical rehabilitation patients (n = 422). Construct validity was further tested by using established instruments.


RESULTS
Ten scales related to self-image, intention of action and goodness of fit show good psychometric qualities (Cronbachs alpha: 0.72 - 0.86). The constructs correlate moderately-to-strongly with personality-oriented scales while correlation with disease-related contents is low.


CONCLUSIONS
The DIAMO is a generic and not disease oriented instrument. It would be expected to facilitate the development of vocational interventions to increase the rehabilitation outcome.
