Characterizing the spectrum of irritability in preadolescence: Dimensional and pragmatic applications.

ABSTRACT:

Objectives

Characterize the dimensional spectrum of preadolescent (PA) irritability, a robust transdiagnostic vulnerability marker, using the youth version of the Multidimensional Assessment Profiles Temper Loss (MAPS-TL-Youth) scale including common and with developmentally specific items. Based on this, derive and validate a clinically optimized irritability screener to flag psychopathology risk in preadolescents.

Methods

The normal:abnormal irritability spectrum was modeled using MAPS-TL-Youth data from the Multidimensional Assessment of Preschoolers Study (MAPS) Study PA wave (n = 340) via item response theory. Both cross-cutting core items from the MAPS scales and developmentally specific items were used to generate this dimension. Stepwise logistic regression was then
