      with executive function, emotion experience, and emotion expressivity in college 
      students.

AB  - Empirical findings suggest that there is an overlap between schizophrenia and 
      obsessive-compulsive disorder (OCD). These disorders also have a high comorbidity 
      rate. However, little is known about the impact of co-occurring schizotypal and 
      obsessive-compulsive traits on executive function, emotion experience, and 
      emotion expressivity in the normal population. The present study examined the 
      prevalence of coexisting schizotypal and obsessive-compulsive traits and the 
      relationship between these two traits in a sample of healthy college students. We 
      also conducted a moderation analysis to explore the effect of these two type of 
      traits on executive function, emotion experience, and emotion expressivity. We 
      recruited 3,319 participants to complete the Schizotypal Personality 
      Questionnaire (SPQ) and the Obsessive-Compulsive Inventory - Revised (OCI-R). A 
      subset of them (n = 575) also completed the Chinese versions of the Dysexecutive 
      Questionnaire (DEX), the Temporal Experience of Pleasure Scale (TEPS), and the 
      Emotional Expressivity Scale (EES). We found that the prevalence of co-occurring 
      schizotypal and OCD traits was 3.33%. All the subscales of the SPQ and the OCI-R 
      significantly correlated with each other. Both traits had a negative impact on 
      executive function and emotion expressivity. The interaction between the 
      disorganization dimension of schizotypal traits and OCD traits had a significant 
      effect on executive function, but not emotion experience or emotion expressivity. 
      This study was limited by its cross-sectional design and recruitment of only 
      college students. These findings suggest that there is an approximately 3% rate 
      of co-occurring schizotypal and obsessive-compulsive traits in a healthy college 
      student sample. The interaction between these two types of traits may influence 
      executive function.
