Objective:
This study aimed to evaluate the psychometric properties of the Japanese version of the Cancer Survivors' Unmet Needs (CaSUN-J) scale among cancer survivors in Japan.
Methods:
The CaSUN-J was developed using standardized translation methodology. Content validity was evaluated by a group of experts, and a pilot test was conducted with a convenience sample of 10 cancer patients. A total of 183 Japanese cancer survivors completed the CaSUN-J. The internal consistency of the scale was examined with Cronbach's α. Construct validity was analyzed using correlations with the physical effects, quality of life (QoL), and age. To assess the factorial validity of the CaSUN-J, confirmatory factor analysis (CFA) was performed.
Results:
The CaSUN-J indicated good readability and high content validity for use as an assessment tool among Japanese cancer survivors. All Cronbach's α coefficients were above the minimum acceptable criterion of ≥0.70. For construct validity, higher physical effect scores, as well as poorer QoL scores and younger patients, were significantly positively associated with higher levels of needs. CFA indicated that the five-factor structure of the CaSUN-J was a good fit to the data.
Conclusions:
The CaSUN-J can serve as a valid and reliable tool to evaluate unmet needs among Japanese cancer survivors.

02:49Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
