Schizotypal traits in a non-clinical sample from Hawai'i.
Most research investigating schizotypal traits, and linking schizotypal personality disorder (SPD) to later schizophrenia, has used Caucasian samples. The lack of cross-cultural comparisons on SPD trait scales inhibits confidence in generalizing the link between SPD and schizophrenia to non-Caucasian populations. The few studies investigating cross-cultural rates of schizotypal traits in non-clinical samples report mixed findings with respect to cultural variation. This study report rates of schizotypal traits in an ethnically and culturally diverse non-clinical sample (N = 353) in the state of Hawaii using the Schizotypai Personality Disorder Questionnaire-B (SPQ-B). Analyses did not detect significantly elevated rates between ethnic groups on the Cognitive/Perceptual, Disorganized, or Total SPQ Score Scales. Significant differences between Caucasians and Asians, as well as between Caucasians and Mixed Ethnicity on the SPQ-B Interpersonal Scale suggest relatively less shyness and more sociability in the Caucasian group. Generally, findings of no significant differences between ethnic groups on the SPQ-B suggest that rates of schizotypy are similar across ethnic groups in Hawaii.
