Validity and reliability of a performance evaluation tool based on the modified Barthel Index for stroke patients

Abstract

Background: The Barthel Index (BI) is a measure of independence in activities of daily living (ADL). In the modified Barthel Index (MBI), a five-point system replaced the original two or three or four point rating system. Based on this modified measure, the performance evaluation tool MBI (PET-MBI) was developed in Japan. Although the reliability and validity of PET-MBI have been verified for older people, the use of this tool in stroke patients has not been evaluated. This study investigated the validity and reliability of PET-MBI for stroke patients. Methods: Ten raters independently determined the BI and PET-MBI scores of stroke patients by direct observation. These patients' ADL were videotaped, and 10 other raters then evaluated the videos privately and assigned PET-MBI scores twice, one month apart. The criterion-related validity of the PET-MBI against the BI was evaluated using the correlation coefficients for their total scores. Furthermore, to assess inter-and intra-rater reliabilities from the results of the first and second sessions, Fleiss' intraclass correlation coefficients (ICCs) were calculated for the total scores, with the lower limits of the 95% confidence interval (95%CI), along with weighted kappa (κ w ) coefficients for agreement in individual tasks of this evaluation tool. ICC and κ w coefficients of 0.81-1.00 were considered to be "almost perfect" agreement.

Effects of Exoskeleton Gait Training on Balance, Load Distribution, and Functional Status in Stroke: A Randomized Controlled Trial

“…Previously reported ICC representing inter-rater reliability for the BI was 0.99. For intra-rater reliability, the value of the ICC was 0.99 (21). In both questionnaires, patients answered the questions themselves as much as possible.…”

Depression and geriatric assessment in older people admitted for hip fracture

“…When scored ≤ 17 a support plan is recommended; 3) Instrumental Activities of Daily Living Scale (IADL) (modified Scale of Lawton and Brody), assesses five items: ability to use the telephone, use of transportation, shopping, responsibility for medication and management of their economy, the rating ranges between 0 (maximum dependence) and 5 (total independence) consistent (Cronbach's Alpha 0.94) 15 ; 4) Basic activities of daily life (BADL) (Barthel Scale modified by Shah et al), with ten items: personal hygiene, bathing, eating, using the toilet, climbing stairs, dressing, moving (walking on a smooth surface or in a wheelchair), transfer chair/bed, stool control and urine control. The results vary between 0 (completely dependent) and 100 points (completely independent), with κ = 0.77 interobserver and κ = 0.85 intraobserver 16 on a numerical scale from zero to ten, in which zero is absence and ten the maximum intensity of pain. The patient tells the number that best indicates that intensity, reliable (r = 0.94), useful even for illiterates (r = 0.71) 19 .…”

Effectiveness of LiuZiJue Qigong versus traditional core stability training for poststroke patients complicated with abnormal trunk postural control: study protocol for a single-center randomized controlled trial

“…The classification of dysfunction is as follows: 100 points = self-care; 61-99 = mild dysfunction; 41-60 = moderate dysfunction; and ≤ 40 = severe dysfunction. The lower the MBI score, the more independent the patients are and the worse their daily living ability [22].…”
