title: Factor Structure and Psychometric Properties of the Brief Illness Perception Questionnaire in Turkish Cancer Patients.
abstract: OBJECTIVE
  The main aim of this study was to investigate the factor structure and psychometric properties of the Brief Illness Perception Questionnaire (BIPQ) in Turkish cancer patients.
  
  
  METHODS
  This methodological study involved 135 cancer patients. Statistical methods included confirmatory or exploratory factor analysis and Cronbach alpha coefficients for internal consistency.
  
  
  RESULTS
  The values of fit indices are within the acceptable range. The alpha coefficients for emotional illness representations, cognitive illness representations, and total scale are 0.83, 0.80, and 0.85, respectively.
  
  
  CONCLUSIONS
  The results confirm the two-factor structure of the Turkish BIPQ and demonstrate its reliability and validity.
