Abstract：BACKGROUND: There were many evaluation scales on activities of daily living(ADL) in rehabilitation medicine, but scale according with rehabilitative nursing programs was less. Therefore, a rehabilitative nursing ADL(RNADL) evaluation scale was studied and designed by the Rehabilitation Center of Zhejiang Province from 2000, and the evaluation content and standard were instituted as well.OBJECTIVE: To make an exploratory discussion of the re-measurement reliability, internal concordance, and reliability of rehabilitative nursing ADL evaluation scales in the assessment of patients' ADL.DESIGN: Design of repeated-measurement.SETTING: Wangjiangshan Convalescent Hospital, Zhejiang Province. Rehabilitation Center, Zhejiang Province.PARTICIPANTS: Forty disordered ADL patients, received rehabilitation care in the Rehabilitation Medical Department of Wangjiangshan Convalescent Hospital, Zhejiang Province from April 2001 to April 2003.METHODS: Intra-rater agreement and inter-rater reliability were undertaken by nurses in 40 residential rehabilitative patients with RNADL scale. Internal concordance was calculated with Cronbach α; evaluation of each item of discharge and admission was performed with RNADL and modified Barthel index(MBI), and then the correlation of admission, discharge and their relationship were analyzed with Pearson.MAIN OUTCOME MEARSURES: Results of reliability and validity detected with the RNADL scale.RESULTS: Reliability of RNADL, intra-rater and inter-rater, was good;each interclass coefficient correlation (ICC) was within 0. 966 -0. 998, r= 0. 996 - 0. 997; The index of intra-rater agreement α = 0. 822; and that of inter-rater reliability α = 0. 925, RNADL internal concordance was good.Comparative study on RNADL and MBI showed that RNADL and MBI changes in discharge and admission had a good dependability( r = 0. 89, P ＜ 0. 001 ).CONCLUSION: RNADL has a high re-measurement reliability, and its internal concordance is good. It has a good correlative validity with MBI, and is a confident and valid scale for the evaluation of rehabilitative nursing ADL.
