difficulties and increased episodes of dysphoric mood 11,14,15 , indicating the clinical significance of emotion regulation ability in schizophrenia. Nevertheless, schizophrenia is a spectrum disorder 16. There is substantial and increasing evidence showing that, although they fall outside the diagnostic boundaries specified in the current diagnostic systems (e.g., the ICD and the DSM), some aspects of the phenomenology of schizophrenia can also be found in the general population 17-19. The phenomenology of "schizotypy" expresses the inter-individual continuum of schizophrenia and refers to a complex construct that is intimately related to psychotic-spectrum disorders or to stable traits that resemble the signs and symptoms of schizophrenia 16,20-22. Individuals with high levels of schizotypal traits have been shown to display alterations in neurocognitive task performance (e.g., deficits in cognition, perception, and motor control) and altered brain structure (e.g., reductions in volume/cortical thickness in frontal and temporal areas, a lower ratio of prefrontal cortical area to temporal cortex area, and abnormalities in subcortical structures) similar to those of patients diagnosed with schizophrenia 23. Highly schizotypal individuals may be undetected carriers of schizophrenia risk alleles 24-26 , and the existence of such a continuum may provide important clues regarding the etiology of schizophrenia 17,23,27. Indeed, although information on deficits in emotion regulation in chronic patients with schizophrenia has been obtained 2,4 , it is not clear whether abnormal emotion regulation is associated with the onset of the disease. The defects in emotion regulation seen in schizophrenia patients may stem from the side effects of medication, since emotion regulation ability may greatly depend on cognitive functions (e.g., executive function and working memory) that are substantially affected by pharmacological treatment 28. Reduced social contact induced by hospitalization may also lead to abnormalities in emotional characteristics 29. Other treatments in patient studies may also affect emotion regulation. For example, a study reported that patients with schizophrenia can effectively downregulate their negative emotions, but 80% of the participants in that study had received cognitive behavior therapy 30. Given the perspective of a schizophrenia continuum, studying individuals who exhibit high schizotypy, are free from problems stemming from the use of chronic medication or other treatments and whose responses can be measured using objective psychometric questionnaires as a model system of schizophrenia can provide a reliable and less expensive 31 method that can be used to better elucidate the relationship between emotion regulation and schizophrenia. Emotion regulation in high schizotypy individuals is also an important topic for investigation in its own right. Longitudinal studies have indicated that measures of schizotypy are directly predictive of psychosis conversion 32 , suggesting high schizotypes as an ...
