Test of Intrarater and Interrater Reliability for the Star Excursion Balance Test

Abstract: [Purpose] The aim of this study was to examine the intrarater and interrater reliability of the Star Excursion Balance Test (SEBT), thereby increasing understanding of its efficient utilization. [Subjects and Methods] There were 67 subjects (49 female; 18 male). For the SEBT, eight lines were made using tape at 45-degree angles from the center of a circle. The experiment was conducted in the following order: the anterior, anterior-medial, medial, posterior-medial, posterior, posterior-lateral, lateral, and anterior-lateral directions. Intraclass correlation coefficients (ICC) (3,1) were used to evaluate the intrarater and interrater reliability (2,1) for each reach distance, while the standard error of measurement (SEM) and smallest detectable distance (SDD) were employed to assess absolute reliability. [Results] For intraratar reliability, the ICC values for all directions ranged from 0.88 to 0.96, SEM values ranged from 2.41 to 3.30, and SDD values ranged from 6.68 to 9.15. For interrater reliability, the ICC values for all directions ranged from 0.83 to 0.93, SEM values ranged from 3.19 to 4.26, and SDD values ranged from 8.85 to 11.82 [Conclusion] The SEBT is a highly reliable tool for measuring dynamic balance. Measurements for intrarater reliability are more reliable than measurements for interrater reliability. When measurement for eight directions was difficult, the SEBT was used. While the anterior, posteromedial, and posterolateral directions employed in the Y Balance Test KitTM can be utilized, this study recommends using the reverse Y Balance Test KitTM method with the posterior direction, not the anterior direction.

A Reliability test system for educational purposes-basic data

Abstract: The IEEE Reliability Test System (RTS) developed by the Application of Probability Method Subcommittee has been used to compare and test a wide range of generating capacity and composite system evaluation techniques and subsequent digital computer programs. A basic reliability test system is presented which has evolved from the reliability education and research programs conducted by the Power System Research Group at the University of Saskatchewan. The basic system data necessary for adequacy evaluation at the generation and composite generation and transmission system levels are presented together with the fundamental data required to conduct reliability-cost/reliability-worth evaluation

The reliability of portable fixed dynamometry during hip and knee strength assessments.

Abstract: Context: Insufficient lower extremity strength may be a risk factor for lower extremity injuries such as noncontact anterior cruciate ligament tears. Therefore, clinicians need reliable instruments to assess strength deficiencies. Objective: To assess the intrarater, interrater, intrasession, and intersession reliability of a portable fixed dynamometer in measuring the strength of the hip and knee musculature. Design: Crossover study. Setting: Sports medicine research laboratory. Patients or Other Participants: Three raters (A, B, C) participated in this 2-phase study. Raters A and B tested 11 healthy college graduate students (2 men, 9 women) in phase 1. Raters A and C tested 26 healthy college undergraduate students (7 men, 19 women) in phase 2. Main Outcome Measure(s): The dependent variables for the study were hip adductor, hip abductor, hip flexor, hip extensor, hip internal rotator, hip external rotator, knee flexor, and knee extensor peak force. Results: The phase 1 intrasession intraclass correlation coefficients for sessions 1, 2, and 3 ranged from 0.88 to 0.99 (SEM 5 0.08–3.02 N), 0.85 to 0.99 (SEM 5 0.26–3.88 N), and 0.92 to 0.96 (SEM 5 0.52–2.76 N), respectively. Intraclass correlation coefficients ranged from 0.57 to 0.95 (SEM 5 1.72– 13.15 N) for phase 1 intersession values, 0.70 to 0.94 (SEM 5 1.42–9.20 N) for phase 2 intrarater reliability values, and 0.69 to 0.88 (SEM 5 1.20–8.50 N) for phase 2 interrater values. Conclusions: The portable fixed dynamometer showed good to high intrasession and intersession reliability values for hip and knee strength. Intrarater and interrater reliability were fair to high, except for hip internal rotation, which showed poor reliability.

A METHOD and RESOURCES for ASSESSING the Reliability of Simulation Evaluation Instruments

Abstract: Aim. This article describes a successfully piloted method for facilitating rapid psychometric assessments of three simulation evaluation instruments: the Lasater Clinical Judgment Rubric, the Seattle University Evaluation Tool, and the Creighton-Simulation Evaluation InstrumentTM. Background. To provide valid and reliable evaluations of student performance in simulation activities, it is important to assess the psychometric properties of evaluation instruments. Method. This novel method incorporates the use of a database of validated, video-archived simulations depicting nursing students performing at varying levels of proficiency. A widely dispersed sample of 29 raters viewed and scored multiple scenarios over a six-week period. Analyses are described including inter- and intrarater reliability, internal consistency, and validity assessments. Results and Conclusion. Descriptive and inferential statistics supported the validity of the leveled scenarios. The inter- and intrarater reliability and internal c...
