While the emotion of anger has become an increasingly important part of clinical assessment, the theoretical and psychometric adequacy of the instruments used to assess anger and hostility have long been questioned. In the present review, we first provide definitions of anger and hostility in order to provide a theoretical context from which to evaluate the scope of current measures of these constructs. Second, we review the major self-report scales used to assess anger and hostility in light of these definitions and provide a detailed evaluation of psychometric evidence concerning their reliability and validity. Finally, we offer specific recommendations concerning how anger and hostility assessment instruments can be improved and expanded. In particular, we note the need for (a) an expansion of anger assessment methods beyond traditional endorsement approaches, (b) scales to assess specific domains of anger experience, (c) scales that assess unique content domains of anger experience and expressions, such as spouse-specific or driving-related anger scales, and (d) scales that assess the clinical aspects of the anger construct.
