“Hypnotic” Attachment to the Night Sky: Theoretical Considerations and an Abbreviated Measure of Noctcaelador

Noctcaelador (attachment to the night sky) was conceptualized as a hypnotic, self-stabilizing attachment most often present among individuals with a flexible, permeable psychic structure. An abbreviated version of the Noctcaelador Inventory (the NI4) was developed and evaluated in six samples (N=747). Across all samples the NI-4 correlated highly with the original scale. The NI-4 possessed good structural validity, criterion validity, convergent and discriminant validity, internal consistency, and test-retest reliability. A 60% reduction of items led to little decrease in the psychometric properties of the scale or its ability to detect relationships with hypothetically related variables. With its brevity, the NI-4 can easily be included as a measure of noctcaelador in longer research protocols and in situations in which time is extremely limited.
