PSAS
Pre-Sleep Arousal Scale - deutsche Fassung
Short abstract
The PSAS is a self-assessment tool and measures the level of cognitive and physical arousal in the pre-sleep phase. Cognitive arousal refers to intrusive cognitions experienced as uncontrollable, while physical arousal refers to the perception of vegetative arousal, for example in the form of racing heart or excessive sweating. It consists of two scales: (1) Scale for recording physical arousal (8 items) and (2) Scale for recording cognitive arousal (7 items). Reliability: The internal consistency was Cronbach's Alpha = .94 (cognitive arousal) and Alpha = .80 (physical arousal). Validity: The validity of the procedure is supported by expected correlations between the PSAS totals and the Pittsburgh Sleep Quality Index (Physical arousal: r = .55; Cognitive arousal: r = .61) and between the PSAS total and the PSQI subscales of sleep latency, sleep duration and sleep efficiency (Cognitive excitation: r = .62, r = .27, r = .20; Physical excitation: r = .40, r = .27, r = .16). In addition, the PSAS subscales could distinguish well between bad and good sleepers.
