Factor structure and measurement invariance of Schizotypal Personality Questionnaire-Brief Revised (Updated) in India.

AIM: Schizotypal Personality Questionnaire-Brief Revised-Updated (SPQ-BRU) is an easy-to-conduct, theoretically consistent, and psychometrically better measure of schizotypal personality. However, its study is limited to developed countries. Thus, in the present study, we tested the factor structure and measurement invariance of SPQ-BRU in India. METHODS: A sample of 734 college students was selected from two sites (n = 614 from Muzaffarnagar in western Uttar Pradesh and n = 120 from Guhana in Haryana). Confirmatory factor analysis was used to test the good fitness of the different models of SPQ-BRU and the measurement invariance across sex and region. RESULTS: The first-order nine-factor model was a better-fit model (among a set of first-order and second-order models), whereas the second-order three-factor model was a more parsimonious good-fit model of SPQ-BRU. The nine-factor model was strongly invariant across sex and region. Women had higher social anxiety, ideas of reference, and lower constricted affect than men. Moreover, the Gohana sample was higher on several schizotypal personality facades than the Muzaffarnagar sample. CONCLUSIONS: The present study supported the cross-cultural validity of schizotypal personality and partially established a reliable and valid SPQ-BRU-Hindi language version.

Hand preference and intolerance of uncertainty: Atypical cerebral lateralization advantages lower intolerance of uncertainty.

Left and inconsistent hand preferences are the markers of atypical brain organization that relate with cognitive and behavioural traits as well as with developmental disorders, whereas intolerance of uncertainty is the trait of inability to bear future uncertainty that mediates anxiety disorders and depression. In the present study, relationship of hand preference with intolerance of uncertainty was studied in a sample of 862 college students (age: M = 21.4 years, SD = 3.12). Results show that left-handers had lower prospective intolerance of uncertainty than right-handers. Furthermore, inconsistent right-handers had lower inhibitive intolerance of uncertainty than consistent right-handers. Thus, the present study supports the likelihood that atypical brain organization advantages tolerance of uncertainty (i.e., lower intolerance of uncertainty). Implications of these findings for understanding the contribution of intolerance of uncertainty to anxiety have been discussed.
