Psychometric Testing of a New Instrument for Assessing Cancer Patient Preparedness for the Survivorship Transition.

Background and Purpose: This study aimed to develop and examine the psychometric properties of the "Preparedness for Transition to Survivorship Care Instrument" (PTSCI) for cancer survivors. Methods: A cross-sectional study of cancer survivors in Korea was conducted to test the reliability and validity of the PTSCI. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and concurrent validity tests were conducted. Results: The EFA showed that the 7-factor structure of a 34-item PTSCI accounted for 61.5% of the total observed variance. In CFA, three competing models were created and compared to a 7-factor solution model. A 6-factor 31-item model showed the best fit and was chosen as the final PTSCI model. PTSCI is significantly associated with quality of life, psychological distress, and health promotion. Conclusions: PTSCI can be helpful in preparing for diverse psychosocial and behavioral issues faced by cancer survivors in the survivorship phase.
