AIM The study aimed at evaluating Reliability, Construct and Concurrent Validity of the Italian version of the Arousability Predisposition Scale (APS, Coren, 1988). METHOD 348 participants (61% F) were divided into 3 main groups: People with insomnia (PI-24.5%); Good Sleepers (GS-17.9%); People with subthreshold insomnia (SC-57.6%) based on the Sleep Disorders Questionnaire (Violani et al., 2004). RESULTS AND CONCLUSIONS Exploratory Factor Analysis evidenced 1 factor accounting for the 38.05% of the variance (communalities higher than 0.30). Chronbach’s Alpha index was high (0.86). Significant differences (p50.030) were evidenced among all groups (F(2,328)=17.21 p=0.001). Results thus suggest that this scale is reliable and valid since it reflects differences across groups defined on the bases of sleep quality.

Abstract

AIM The study aimed at evaluating Reliability, Construct and Concurrent Validity of the Italian version of the Arousability Predisposition Scale (APS, Coren, 1988). METHOD 348 participants (61% F) were divided into 3 main groups: People with insomnia (PI-24.5%); Good Sleepers (GS-17.9%); People with subthreshold insomnia (SC-57.6%) based on the Sleep Disorders Questionnaire (Violani et al., 2004). RESULTS AND CONCLUSIONS Exploratory Factor Analysis evidenced 1 factor accounting for the 38.05% of the variance (communalities higher than 0.30). Chronbach’s Alpha index was high (0.86). Significant differences (p50.030) were evidenced among all groups (F(2,328)=17.21 p=0.001). Results thus suggest that this scale is reliable and valid since it reflects differences across groups defined on the bases of sleep quality.
