Conceptualizing schizotypal ambivalence: factor structure and its relationships.

Ambivalence is an important facet of pathology that has received limited attention despite its importance in understanding negative emotionality within schizophrenia spectrum disorders. Central to understanding the role of ambivalence in schizophrenia is characterizing its manifestation within schizotypal individuals-those with the purported genetic liability for schizophrenia. The present study used the Schizotypal Ambivalence Scale (SAS) to examine the nature of ambivalence. An exploratory factor analysis of SAS scores revealed three factors: interpersonal, indecision, and contradictory feelings of ambivalence. Group differences in SAS scores were found such that psychometrically defined schizotypal individuals reported higher levels of ambivalence than controls, and different schizotypy traits exhibited different relationships with SAS factors and quality of life. The inclusion of implicit and explicit measures of positive and negative attitudes revealed that individuals with schizotypy might lack insight into their affective experiences as suggested by the incongruence between our explicit and implicit measures of social attitudes. As hypothesized, the Schizotypal Personality Questionnaire trait dimensions associated with greater SAS ambivalence and the different trait dimensions of schizotypy showed both common and disparate relationships with the ambivalence factors. The current results support the notion that schizotypal ambivalence is a multifaceted construct that not only is affective but also reflects broader processes that dynamically interact with one another to influence functional outcomes.
