Psiquiatria Alemanya (República Federal) Diagnòstic psiquiàtric Psychiatry Germany (West) Psychiatric diagnosis Background: The Functioning Assessment Short Test (FAST) is an interviewer-administered scale assessing functional impairment originally developed for psychiatric patients. Objectives: To adapt the FAST for the general population, we developed a self-administered version of the scale and assessed its properties in a pilot study. Methods: The original FAST scale was translated into German via forward and backward translation. Afterwards, we adjusted the scale for self-administered application and inquired participants from two ongoing studies in Germany, 'STAAB' (Würzburg) and 'BiDirect' (Münster), both recruiting subjects from the general population across a wide age range (STAAB: 30-79 years, BiDirect: 35-65 years). To assess reliability, agreement of self-assessment with proxy-assessment by partners was measured via intraclass correlation coefficient (ICC) over the FAST score. Construct validity was estimated by conducting correlations with validated scales of depression (PHQ-9), anxiety (GAD-7), and health-related quality of life (SF-12) and regression analyses using these scales besides potentially disabling comorbidities (e.g. Chronic Back Pain (CBP)). Results: Participants (n=54) had a median age of 57.0 years (quartiles: 49.8, 65.3), 46.3% were female. Reliability was moderate: ICC 0.50 (95% CI 0.46-0.54). The FAST score significantly correlated with PHQ-9, GAD-7, and the mental sub-scale of SF-12. In univariable linear regression, all three scales and chronic back pain explained variance of the FAST score. In multivariable analysis, only CBP and the SF-12 remained significant predictors. Conclusion: The German self-administered version of the FAST yielded moderate psychometric properties in this pilot study, indicating its applicability to assess functional impairment in the general population. 2021-04-21T14:57:47Z 2021-04-21T14:57:47Z 2020-09-25 2021-04-21T14:57:47Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1745-0179 https://hdl.handle.net/2445/176541 703979 33088336 eng Reproducció del document publicat a: https://doi.org/10.2174/1745017902016010192 Clinical practice and epidemiology in mental health : CP & EMH, 2020, vol. 16, p. 192-203 https://doi.org/10.2174/1745017902016010192 cc-by (c) Riegler, Christoph et al., 2020 http://creativecommons.org/licenses/by/3.0/es info:eu-repo/semantics/openAccess 12 p. application/pdf BioMed Central Articles publicats en revistes (Medicina)
