Abstract
Schizotypy is a useful and unifying construct for examining the etiology, development and expression of schizophrenia-spectrum psychopathology. Studies have shown that positive, negative, and disorganized schizotypy dimensions are differentiated by mean levels of psychotic-like, negative, and disorganized schizotypic experiences in daily life, and by temporal dynamics of affect. Extending this work, the present dissertation employed experience sampling methodology in a large non-clinically ascertained sample (n=693) to examine psychotic-like, negative, and disorganized schizotypic experiences in daily life, as well as the temporal dynamics (variability, reactivity, inertia, and instability) of these experiences in multidimensional schizotypy. We first replicated the mean-level associations between multidimensional schizotypy and schizotypic experiences in daily life. Second, we established that schizotypic experiences in general exhibit dynamic patterns in daily life. Lastly, positive, negative, and disorganized schizotypy demonstrated hypothesized, differential patterns of schizotypic dynamics. Disorganized schizotypy demonstrated the most robust associations, including intensity, variability, and inertia of disorganized schizotypic experiences. Disorganized schizotypy also moderated reactivity of psychotic-like and disorganized schizotypic experiences following previously reported stress. Positive schizotypy was associated with intensity and variability of psychotic-like experiences. Negative schizotypy was associated with intensity and variability of negative schizotypic experiences. The findings indicate that schizotypy dimensions can be differentiated by both mean levels and temporal patterns of psychotic-like, negative, and disorganized schizotypic experiences in daily life, with disorganized schizotypy uniquely characterized by stress reactivity.
