An Exploratory Investigation of Noctcaelador and Sleep Disturbance Ascribed to Worry

Noctcaelador, defined as psychological attachment to the night sky, has been linked to personality traits, coping, and habitual sleep-length. However, little is known about its relationship with sleep disturbance ascribed to worry (SAW), a tendency to attribute sleep difficulties to worry. The present exploratory study examined associations between noctcaelador and SAW in a sample of 235 university students who completed the Noctcaelador Inventory and the Sleep Disturbance Ascribed to Worry Scale. Noctcaelador and SAW were modestly but significantly correlated (r = .23, p < .001). Item-level stepwise regression analyses indicated that waking from sleep worrying was the only SAW component uniquely predictive of noctcaelador, whereas enjoyment of going outside to view the night sky was the only noctcaelador item uniquely predictive of SAW. These findings suggest that noctcaelador may intersect with cognitive–affective processes linked to nocturnal worry and may reflect behavioral tendencies relevant to nighttime self-regulation. Implications and avenues for future research are discussed.
