Abstract
OBJECTIVE: To validate the International Classification of Functioning, Disability and Health (ICF) Generic-6 in daily routine clinical practice in Mainland China. Specific objectives were to analyze (1) interrater reliability, (2) convergent validity, (3) known group validity, and (4) predictive validity of the ICF Generic-6. DESIGN: Multicenter prospective cohort study. SETTING: Fifty hospitals from 20 provinces of Mainland China. PARTICIPANTS: A total of 4510 patients from departments of rehabilitation, orthopedics, neurology, cardiology, pneumology, and cerebral surgery of the participating hospitals with different health conditions were included in this study. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: The assessment was undertaken by nurses with ICF Generic-6 in combination with a numeric rating scale. Interrater reliability was evaluated with intraclass correlation coefficients (ICC). Convergent validity was evaluated with Spearman correlation coefficients between ICF Generic-6 and Medical Outcomes Short Form (SF)-12 items. Known group validity was examined by comparing discharge scores between different discharge destinations. Predictive validity was determined by using ICF Generic-6 baseline scores for estimating length of hospital stay with a loglogistic survival model with gamma shared frailty and cost of in-hospital treatment with a mixed effects generalized linear regression model of the gamma family. RESULTS: The interrater reliability of items and score of ICF Generic-6 was good with ICCs ranging from 0.67-0.87. ICF Generic-6 items were further correlated with respective SF-12 items. Discharge scores of patients differed significantly by discharge destination. The ICF Generic-6 admission score was a significant predictor of length of stay and treatment cost. CONCLUSIONS: The ICF Generic-6 administered in combination with a 0-10 numeric rating scale is a reliable and valid tool for the collection of minimal information on functioning across various clinical settings.
