Abstract
PurposeAnger and irritability are common and impairing symptoms in children. The PROMIS Anger scales assess self- and parent-reported irritable and angry mood over the past 7 days. The aim of this study was to evaluate the psychometric properties of the German version of the PROMIS Parent Proxy Short Form v1.0—Anger and to provide normative data.MethodsTo evaluate the psychometric properties, data from the study ADOPT Epidemiology were used. In this study, the PROMIS Anger Scale was administered to a population-based sample of n = 8746 parents of children aged 8–12 years. Psychometric analyses were carried out including the investigation of distribution characteristics, factor structure, model fit, internal consistency, and congruent validity. Normative data were calculated as percentile ranks and T-scores.ResultsThe PROMIS Anger Scale demonstrated good psychometric properties, including satisfactory distribution characteristics, unidimensionality, good internal consistency as well as congruent validity. German normative data for the PROMIS Anger Scale are presented.ConclusionBased on first psychometric analyses, the German version of the PROMIS Anger Scale can be recommended for use in research and practice; however, further investigations using clinical data are needed. The normative data will allow researchers and clinicians an interpretation of the test scores in future applications.

Summary
Anger is a negative emotional state that is elicited by interpersonal provocation or frustration and often manifests itself in verbal and/or physical aggressive behavior [1, 2]. Irritability is conceptualized as a low threshold for experiencing symptoms of negative affectivity such as anger in response to frustration. Anger, frustration, aggression, and irritability are interrelated psychological constructs [3]. Anger and irritability are common and impairing symptoms in children and adolescents and are among the most common reasons for referrals to child and adolescent mental health services [3]. Since irritability can have serious psychosocial implications and can predict long-term adversities [7, 8], the reliable and valid assessment of anger and irritability is important in order to identify and treat affected children at an early stage
