Hyperarousal Scale: Italian Cultural Validation, Age and Gender Differences in a Nonclinical Population

Objectives. Studies on hyperarousal have increasingly developed in the last decade. Nevertheless, there are still very few valid measures of hyperarousal. The aim of the study is to verify the psychometric properties of the Italian version of the Hyperarousal Scale (H‐Scale), in order to provide researchers with a valid measure for the target population. Method. The questionnaire was translated, back‐translated, pre‐tested, and cross‐culturally adapted. Subsequently, the Italian version of the H‐Scale, the Anxiety Sensitivity Index (ASI‐3) and the Health Survey Questionnaire (SF‐36) were administered to 982 adults, 456 males and 526 females, aged from 18 to 80 years (M = 35.61 ± 12.47). Results. Cronbach’s alpha of the translated H‐Scale was 0.81. Furthermore, positive correlations with the ASI‐3 and negative correlations with the SF‐36 emerged. The H‐Scale is also sensitive to catch age and gender differences. Conclusions. The Italian version of the H‐Scale demonstrated good reliability and validity. Its sufficient discriminative and evaluative psychometric properties provide the theoretical evidence for further application in evidence‐based research studies.
