Affective dynamics in daily life are differentially expressed in positive, negative, and disorganized schizotypy.

Schizotypy and schizophrenia are associated with disruptions in the experience of affect. Temporal patterns of affect, or affective dynamics, offer unique information about the expression of multidimensional schizophrenia-spectrum psychopathology. The present study employed experience sampling methodology to examine affective intensity, inertia, variability, reactivity, and instability in positive, negative, and disorganized schizotypy in nonclinically ascertained young adults ( n = 275). As hypothesized, disorganized schizotypy demonstrated the most robust associations with affective dynamics and was characterized by elevated intensity, reactivity, and variability of negative affect. Disorganized schizotypy was also associated with instability of negative affect, but this relation was better accounted for by mean negative affect, which was elevated in disorganized schizotypy. Negative schizotypy was characterized by diminished intensity and variability of positive affect as expected, but was unassociated with affective inertia. Finally, as hypothesized, positive schizotypy was associated with elevated intensity and variability of negative affect at the bivariate level, but was unassociated with affective dynamics when including disorganized schizotypy in the model. These findings indicate that the schizotypy dimensions are differentiated by both mean levels and dynamics of affect, and that affective dynamics convey unique information about multidimensional schizotypy beyond mean levels of affect. The findings provide further support for the multidimensional model of schizotypy. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
