Validation of the Malay Version of the Fear of Progression Questionnaire-Short Form (FoP-Q-SF-M) in Malaysian Cancer Patients

ABSTRACT

@#Introduction: Fear of cancer progression may lead to worsening of psychological complications of cancer and affects the quality of life of cancer patients. Hence, fear of cancer progression needs to be monitored. This study translated the original English version of the Fear of Progression Questionnaire-Short Form (FoP-Q-SF) into the Malay language and investigated the reliability and validity of the Malay version of the FoP-Q-SF (FoP-Q-SF-M) among Malaysian cancer patients. Methods: Concurrent translation and back translation of the English version of the FoP-Q-SF to the FoP-Q-SF-M was performed, and the FoP-Q-SF-M and the Malay version of the Cancer Therapy Satisfaction Questionnaire (CTSQ-M) (as a comparison to assess the discriminant validity of the FoP-Q-SF-M) were administered to 200 cancer patients with different sites, stages, and duration of cancer diagnosis. Results: The CTSQ-M exhibited excellent internal consistency (Cronbach’s α= 0.927) as well as demonstrated good convergent and discriminant validity. Exploratory factor analysis of the FoP-Q-SF-M extracted one factor with twelfth items, thereby this supports the single-factor model reported by the English version of the FoP-Q-SF. Conclusion: The FoP-Q-SF-M exhibited acceptable psychometric properties and valid for use to assess fear of cancer progression in the Malaysian cancer population.
