Abstract. The vulnerability for schizophrenia-spectrum disorders is expressed across a continuum of clinical and subclinical symptoms impairment known as schizotypy. Schizotypy multidimensional construct with positive, negative, disorganized dimensions. Openness to experience offers useful personality domain exploring This study examined the factor structure openness its relation schizotypy usi...

BACKGROUND Psychometrically identified positive schizotypy and negative schizotypy are differentially related to psychopathology, personality and social functioning. However, little is known about the experience and expression of schizotypy in daily life and the psychological mechanisms that trigger psychotic-like experiences. METHOD The present study employed experience sampling methodology ...

OBJECTIVES Schizotypy relates to rejection sensitivity (anxiety reflecting an expectancy of social exclusion) and neuroticism (excessive evaluation of negative emotions). Positive schizotypy (e.g., perceptual aberrations and odd beliefs) and negative schizotypy (e.g., social and physical anhedonia) could relate to altered attention to rejection because of neuroticism. METHODS Forty-one health...

Positive and negative schizotypy exhibit differential patterns of impairment in social relations, affect, and functioning in daily life. However, studies have not examined the association of schizotypy with real-world expression of psychotic-like, paranoid, and negative symptoms. The present study employed experience-sampling methodology (ESM) to assess positive and negative schizotypy in daily...

INTRODUCTION Correlational methods, unlike cluster analyses, cannot take into account the possibility that individuals score highly on more than one symptom dimension simultaneously. This may account for some of the inconsistency found in the literature of correlates of schizotypy dimensions. This study explored the clustering of positive and negative schizotypy dimensions in nonclinical subjec...

The present study examined the validity of psychometrically assessed positive and negative schizotypy in a study of 214 Spanish young adults using interview and questionnaire measures of impairment and psychopathology. Schizotypy provides a useful construct for understanding the etiology and development of schizophrenia and related disorders. Recent interview, laboratory, and experience samplin...

BACKGROUND The disorganized and negative dimensions of schizotypy are characterized by cognitive disorganization and anhedonia, respectively. The aim of the study was to investigate the relationships between these two dimensions of schizotypy by taking into account ambivalence and the distinction between consummatory and anticipatory anhedonia. METHODS Dimensional analysis and categorical ana...

The present study examined the factor structure underlying the Wisconsin Schizotypy Scales and the validity of these dimensions. Confirmatory factor analysis with 6137 nonclinical young adults supported a 2-factor model with positive and negative schizotypy dimensions. As predicted, the schizotypy dimensions were differentially related to psychopathology, personality, and social impairment. Bot...

People high in schizotypy, a risk factor for schizophrenia-spectrum disorders, can have negative symptoms, including diminished experience of motivation/pleasure (MAP) and emotional expressivity (EXP). Additionally, people high in schizotypy often report elevated depressive symptoms, which are also associated with diminished MAP and EXP. In this study, we examined whether negative symptoms were...

Schizotypy and schizophrenia involve social disinterest (anhedonia) and social anxiety. To clarify the role of social dysfunction in schizotypy, this study examined the relationship of social anxiety and social anhedonia in 364 young adults. As hypothesized, there was a moderate association between these constructs, which diminished after partialing out positive schizotypy. A series of CFAs fou...
