title: Study of the psychometric qualities of the Brief Social Phobia Scale (BSPS) in Brazilian university students.
abstract: OBJECTIVE
  To perform a psychometric analysis of the Brazilian version of the Brief Social Phobia Scale (BSPS).
  
  
  METHODS
  Hundred and seventy-eight university students of both genders aged on average 21.2 years and identified as Social Anxiety Disorder (SAD) cases and non-cases was studied, with the structured clinical interview for DSM-IV being used as a parameter. The different instruments were applied in an individual manner in the presence of a rater and of an observer.
  
  
  RESULTS
  The BSPS showed adequate internal consistency (0.48-0.88) and concurrent and divergent validity with the Beck Anxiety Inventory (BAI) (0.21-0.62), Social Phobia Inventory (0.24-0.82) and Self Statements During Public Speaking Scale (SSPS) (0.23-0.31). Discriminative validity revealed a sensitivity of 0.88-0.90 and a specificity of 0.81(0.83 for cut-off notes of 18/19. Factorial analysis demonstrated the presence of six factors that jointly explained 71.79% of data variance. Construct validity indicated some limits of the scale regarding the diagnosis of SAD. Inter-rater reliability was strong (0.86-1.00, p<0.001).
  
  
  CONCLUSIONS
  The BSPS is adequate for use with university students, although further studies in different cultures, samples and contexts are still necessary.
