Psychometric Testing of the Traditional Chinese Version of the Fear of Progression Questionnaire-Short Form in Cancer Survivors

Background and Purpose: Fear of cancer recurrence (FCR) is a frequent psychological adverse effect among cancer survivors. This study aimed to test the psychometric properties of the Traditional Chinese version of the 12-item Fear of Progression Questionnaire-Short Form (FoP-Q-SF). Methods: An online survey was conducted with 311 cancer survivors in Hong Kong. The factor structure, known-group validity, and internal consistency reliability were examined. Results: The values measuring validity is good, with acceptable goodness-of-fit indexes (RMSEA = 0.073, SRMR = 0.042, CFI = 0.954), moderate to large correlations with unmet needs (0.339-0.816), being female, younger, had completed treatment <= 2 years, and had undergone chemotherapy/radiotherapy scored significantly higher on the FoP-Q-SF. The Cronbach's alpha of the scale was.922. Conclusion: High validity and reliability indicate the scale's value in assessing FCR in Hong Kong cancer survivors.
