Current international efforts to implement ICF in rehabilitation clinics include the implementation of ICF Core Sets and the development of simple, intuitive descriptions for the ICF Generic-30 Set (also called Rehabilitation Set). The present study was designed to operationalize these ICF tools for clinical practice in Japan. This work included 1) the development of the Japanese version of the simple, intuitive descriptions for the ICF Generic-30 Set, 2) the development of a rating reference guide for Activity and Participation categories, and 3) the examination of the interrater reliability of rating Activity and Participation categories. Methods The Japanese version of the simple, intuitive descriptions for the ICF Generic-30 Set was developed following the process employed to develop the Chinese and Italian versions. For further operationalization of this ICF Set in practice, a rating reference guide was developed. The development of the rating reference guide involved the following steps: 1) a trial of rating patients by several raters, 2) cognitive interviewing of the raters to analyse the thinking process involved in rating, 3) drafting of the rating reference guide, and 4) review by ICF specialists to confirm consistency with the original ICF concepts. After the rating reference guide was developed, interrater reliability of the rating with the reference guide was determined. Interrater reliability was examined using weighted kappa statistics with linear weight. Results Through the pre-defined process, the Japanese version of the simple, intuitive descriptions for 30 categories of the ICF Generic-30 Set and the rating reference guides for 21 Activity and Participation categories were successfully developed. The weighted kappa statistics ranged from 0.61 to 0.85, showing substantial to excellent agreement of the ratings between raters. Conclusions The present study demonstrates that ICF categories can be translated into clinical practice. Collaboration between clinicians and researchers would further enhance the implementation of the ICF in Japan.}, language = {en} } @article{MukainoProdingerOkouchietal.2020, author = {Mukaino, M. and Prodinger, Birgit and Okouchi, Y. and Mizutani, K. and Senju, Y. and Suzuki, M. and Saitoh, E.}, title = {Development and assessment of a home environment checklist to evaluate mismatch between patients' ability and home environment}, series = {Annals of Physical and Rehabilitation Medicine}, volume = {63}, journal = {Annals of Physical and Rehabilitation Medicine}, number = {4}, pages = {288 -- 295}, year = {2020}, abstract = {Background Modification of the home environment, together with rehabilitative interventions, is important for maximizing the level of functioning after an individual with disability undergoes rehabilitation in the hospital. Objectives We developed a simple screening scale - the home environment checklist (HEC) - to identify any mismatch between an individual's abilities and their home environment to help clinicians monitor the appropriateness of the home environment to which individuals with disability will be discharged. We also examined the psychometric properties of the HEC. Methods The HEC was developed by a multidisciplinary panel of rehabilitation experts using information routinely collected in rehabilitation clinics before discharge. The reliability of the checklist was assessed in 60 individuals undergoing rehabilitation. The inter-rater agreement and internal consistency of the scale were assessed by weighted kappa statistics and Cronbach's alpha, respectively. Rasch analysis was performed with 244 rehabilitation individuals to evaluate the internal construct validity, and the known-groups validity was confirmed by a comparison of the daily activity levels of 30 individuals with disabilities under rehabilitation to the HEC score. Results The HEC was developed as a simple, 10-item checklist. The weighted kappa statistics ranged from 0.73 to 0.93, indicating excellent inter-rater reliability. Cronbach's alpha was 0.92, indicating high internal consistency. Rasch analysis with a testlet approach on 3 subscales demonstrated a good fit with the Rasch model (χ2 = 13.2, P = 0.153), and the demonstrated unidimensionality and absence of differential item functioning supported the internal construct validity of the HEC. HEC scores were significantly different (P < .01) among individuals with disability and 3 levels of restrictions in their activities (no limitation, home-bound, and bed-bound), which demonstrates the known-groups validity of the HEC. Conclusions The HEC has good reliability and validity, which supports its utility in rehabilitation clinics.}, language = {en} }
