The Pathology of Imagination: Picturing the Worst.

Imagination, often celebrated for its role in creativity and development, also may be a feature in a range of personality pathology and psychopathology. This pre-registered study evaluates the relationship between imagination and maladaptive personality traits using the Four-Factor Imagination Scale and Personality Inventory for DSM-5. Large-scale, multinational, cross-sectional data (<italic>N</italic> = 114,559) were collected from the SAPA-Project using a planned-missingness design. Functional sample size (pairwise-<italic>n</italic> = 600) was derived from the mean number of pairwise-complete administrations of all items. Significant associations were found between imagination and PID-5 facets saturated with negative affect and psychoticism. Extreme groups analysis demonstrated participants with non-normative levels of PID-5 Depressivity and Anxiousness had elevated levels of emotionally negative imagination (mean <italic>d</italic> = 1.14, <italic>p</italic> < .001); non-normative Perceptual Dysregulation and Emotional Lability featured greater overall imaginative activity (mean <italic>d</italic> = 1.00, <italic>p</italic> < .001). Item-level analyses using machine learning revealed the content of PID-5 items predicted facet-level imagination scores, suggesting imagination features in some pathological traits. All statistical analyses are reproducible and publicly available in the Supplemental Materials file. [ABSTRACT FROM AUTHOR]
