Abstract

Objective

To assess the accuracy and reliability of peer exercise leader ratings of balance exercise intensity using the Balance Intensity Scale Therapist version – Global Rating of Effort (BIS-T GRE).

Design

Prospective cohort study.

Setting

Two community peer-led exercise programs in Canada.

Participants

Fourteen leaders (N=14) who were currently teaching or had taught a class in the past year and had completed introductory training on the BIS-T GRE.

Interventions

A 90-minute online facilitated training, including practice rating videos of older adults performing balance exercise tasks and moderated discussion.

Main Outcome Measures

(1) Accuracy of peer exercise leaders’ BIS-T GRE ratings for 8 videos of older adults performing balance exercise tasks in 2 independent rating sessions compared with expert ratings; and (2) interrater and test–retest reliability of BIS-T GRE ratings.

Results

Mean ratings were the same or lower than expert scores, with significant differences in 4 videos in session 1 and 5 videos in session 2 (all P<.03). A total of 97% of ratings had acceptable accuracy in session 1, and 90% in session 2 (P=.027). Interrater reliability was excellent (intraclass coefficient range=0.980-0.988), and test–retest reliability was good to excellent (intraclass coefficient range=0.744-0.986).

Conclusions

Peer exercise leaders in Canadian community programs can accurately and reliably rate balance exercise intensity in older adults using the BIS-T GRE.

同伴运动领导可以准确可靠地评价老年人运动强度的平衡强度量表：一项前瞻性队列研究

目的利用平衡强度量表（BIS-T GRE）评估同伴运动领导者对平衡运动强度评分的准确性和可靠性。前瞻性队列研究。加拿大的两个社区同伴领导的锻炼项目。参与者14位领导（N=14），他们目前正在教学或在过去一年中曾教过一堂课，并完成了BIS-T GRE的入门培训。干预：一个90分钟的在线促进训练，包括老年人进行平衡锻炼任务的练习评分视频和主持讨论。(1)同伴运动领导对8段老年人平衡运动任务视频的BIS-T GRE评分与专家评分的准确性比较；(2) BIS-T GRE评分的解释信度和重测信度。结果平均评分与专家评分相同或低于专家评分，第1组有4个视频，第2组有5个视频，差异有统计学意义（p < 0.05）。在第一阶段，共有97%的评分具有可接受的准确性，在第二阶段，有90%的评分具有可接受的准确性（P= 0.027）。量表间信度极好（类内系数范围=0.980 ~ 0.988），重测信度极好至极好（类内系数范围=0.744 ~ 0.986）。结论加拿大社区项目的speer运动领导者可以使用BIS-T GRE准确可靠地评估老年人的平衡运动强度。
