Motivation Insights®: Instrument Validation Manual

TTI’s Personal Interests, Attitudes and Values 2 instrument (PIAV2) is anchored in design and development of their prior PIAV instrument. During the late summer of 2002, TTI initiated a review of the reliability of the six scales and the associated items. That assessment utilized a sample of 2136 cases from 43,325 available cases. These data contained 60% males and 40% females. These responses represent a diverse range of those utilizing this instrument. This assessment of the revised instrument is based on 1,130 responses containing 50.5% males and 49.5% females collected during the late summer of 2003 through the TriMetrix distribution system.
