163. Association of Sleep, Anxiety, and Psychotic-Like Experiences
Anxious thoughts can lead to and may exacerbate sub-threshold, non-clinical symptoms of psychosis (psychosis-like experiences; PLEs). The mechanisms through which anxiety impacts PLEs are, however, largely unknown. Sleep disturbances are prevalent and can be distressing for individuals who experience PLEs and/or anxious thoughts. The present study seeks to investigate the relation between anxiety, sleep, and PLEs within an undergraduate population who previously reported experiencing psychosis-spectrum symptoms. We hypothesized that sleep behavior will moderate the relation between anxious thoughts and PLEs. Using Ecological Momentary Assessment (EMA) methods, participants were sent questions via mobile phones that probed levels of anxiety, sleep quality and quantity, and PLEs six times a day for one full week. Such assessment methods gather information on social and emotional state of the individual in real time, aiming to limit recall bias and increase ecological validity. Results will serve to further elucidate the relation between all three variables and may aid in determining intervention targets for those experiencing PLEs.
