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.
