Validity and reliability of the Finnish version of the Functioning Assessment Short Test (FAST) in XXXX .

@entity1 @entity162
BACKGROUND: The Functioning Assessment Short Test (FAST) was developed for the clinical evaluation of functional impairment of @entity1 suffering from @entity162 . The aim of this study was to validate the Finnish version of FAST. METHODS: Translation and back-translation of FAST were performed. Fifty @entity1 with the Diagnostic and Statistical Manual of Mental Disorders-Fourth edition (DSM-IV) bipolar type I and II were interviewed at the @entity162 Research and Treatment Centre, City of Helsinki, Finland. @entity1 completed the FAST, the Social and Occupational Functioning Assessment Scale (SOFAS) of DSM-IV, and the Sheehan Disability Scale (SDS) as part of the assessment. Internal consistency and correlations between FAST and SOFAS and SDS were analysed. Twenty-five @entity1 participated in a reliability assessment carried out 1 week apart by a different rater. RESULTS AND DISCUSSION: The internal consistency coefficient obtained was very good, with a Cronbach alpha of 0.870. Reliability of FAST was also found excellent (correlation between two measures r   =   0.896, p   <   0.001). A highly significant negative correlation between FAST and SOFAS scores was found (r   =   -0.723, p   <   0.001). FAST and SDS were also highly significantly correlated (r   =   0.742, p   <   0.001). CONCLUSIONS: The psychometric validity and reliability of FAST in the Finnish sample of @entity1 with @entity162 types I and II were good.
