Irritability Toward People Questionnaire Test - Symptoms and Signs
This measure assesses self-reported irritability and negative reactivity in interpersonal interactions. The Irritability Toward People Questionnaire is intended to help characterize how readily an individual becomes annoyed with others and the perceived impact on day-to-day relationships (Novaco & Deffenbacher). It consists of 22 items and typically takes about 5 minutes to complete.
Results are generally used to support clinical case formulation and to inform discussion of interpersonal stress, conflict patterns, and treatment targets. The Irritability Toward People Questionnaire is not diagnostic on its own; scores should be interpreted in the context of presenting concerns, clinical interview findings, and other relevant measures.
