Bioelectrical impedance analysis ( BIA) is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body, and the voltage is measured in order to calculate impedance ( resistance and reactance) of the body. Most body water is stored in muscle.

video-based instructional materials (VBIMs) have been sought (Donkor, 2010). The use of video in the delivery of practical lessons has some advantages that are acknowl-edged in the literature.

In addition, each section is designed to test a listener’s ability in both short-term and long-term listening contexts (e.g., conversations, lectures, etc.).
Finally, researchers surveyed an additional 25 pediatric audiologists and 25 caregivers unfamiliar with the IT-MAIS to assess the videos' content validity. Analyses showed that the audiologists and caregivers agreed on which video best depicted each of the 10 ITMAIS questions, thus suggesting that the videos had strong content validity.
