A study of the suitability of videophones for psychometric assessment

In order to determine whether videophones are appropriate communication tools for psychometric assessments, we need to determine whether the quality of videophones is adequate to enable this type of assessment or whether it places a burden on the communication. The purpose of this study is to measure the subjective quality of video and audio features of commercially available videophones in the context of a psychometric assessment session. We recruited 52 subjects who used the videophone to participate in a psychometric assessment using the Perceived Stress Scale. After each session, participants filled out the ITU-T P.920 that assesses the context-specific quality of the video-call. Findings indicate that the overall audio and image quality of the video-call was satisfactory and participants perceived the videophones as useful in the context of psychometric assessment. These findings strengthen the call for use of video mediated communication in home and hospice settings and disease management.
