Note: not significant (N.S.); Launay-Slade Hallucination Scale (LSHS) ranges from 0–48; Scores on the depressive symptom frequency subscale of the Community Assessment of Psychic Experiences (CAPE) range from 0–24. Analysis of group differences for cortisol was conducted utilizing analyses of covariance (ANCOVA) with sampling time of day as a covariate. The units of cortisol are listed in μg/dl. AUCg refers to the total area under the curve with respect to ground.
