“…IRT is also useful in identifying other areas for improvement of a scale, such as item redundancy and poorly performing items. While IRT has been advantageous for confirming the psychometric soundness of many instruments, such as the Parenting Scale (Lorber, Xu, Slep, Bulling, & O'Leary, ), the Autonomy over Tobacco Scale (Wellman, Edelen, & DiFranza, ), and measures of teen dating violence attitudes (Edelen, McCaffrey, Marshall, & Jaycox, ), the technique is rarely applied to research on SOC.
