Clinical Psychology Psychology irritability children mothers scale development Research on the measurement of youth irritability lacks consensus, and there is need to address the underdeveloped literature on clinical assessment of the tonic (i.e., persistent irritable/angry mood) and phasic (i.e., temper outbursts) components of irritability. Currently, no measure has been developed or validated that assesses tonic/phasic irritability, which presents concerns with existing evidence related to the assessment and treatment of youth irritability. The current study developed and provided initial psychometric support for a parent-report, dimensional rating scale of irritability using empirically-supported steps to scale development. Mothers of children ages 6-12 (N = 397) were recruited through Amazon’s Mechanical Turk (MTurk) and completed items measuring tonic/phasic irritability and related problems. Exploratory factor analysis (EFA) derived a 22-item, two-factor scale that demonstrated excellent reliability and showed convergent validity with other measures of child psychological problems. The ability for tonic and phasic irritability to differentially predict outcomes was not supported, and evidence for using the scale as a screening tool was mixed. These results provided, to my knowledge, support for the first tonic/phasic irritability scale and have important implications for research and practice related to youth irritability. 2020 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou160314468745346 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou160314468745346 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
