Confirmatory Factor Structure and Predictive Validity of the Early Identification System-Student Report in a...

The purpose of this paper is to confirm the factor structure, examine the invariance, and investigate the predictive validity using disciplinary data for 5262 high school students who completed the Early Identification System-Student Response (EIS-SR). The development and theory of the EIS-SR is discussed along with prior work. Building off of prior factor analytic work with a separate sample, it was hypothesized the items of the EIS-SR would coalesce into seven factors representing Externalizing Behavior, Internalizing Behavior, Peer Relationship Problems, School Disengagement, Emotional Dysregulation, Attention and Academic Issues, and Relational Aggression. Furthermore, it was hypothesized that EIS-SR scores would be invariant with regard to gender and grade level. Lastly, it was hypothesized that students with high EIS-SR subscale scores would be predictive of school discipline events. Our analyses indicated the EIS-SR did fit the previously observed factor structure with the items loading on seven distinct scales. Tests for measurement invariance indicated support that the EIS-SR measured the seven factors equally well regardless of both gender and grade level. Lastly, EIS-SR subscale scores predicted spring office disciplinary referrals, both in and out of school suspensions, and attendance.
