Abstract: ABSTRACT Background Personal health-related resources are essential for women with breast cancer, as these help them to maintain their own health and well-being during cancer care. Nurses play an important role in providing support to identify personal health-related resources of women during cancer treatments. Purpose To develop and test the psychometric properties of a new self-assessment personal health-related resources (PHRR) instrument for working-age women receiving breast cancer care. Methods A four-phase instrument development process was used. The data were analysed using the content validity index, content validity ratio and exploratory factor analysis. Reliability was tested using Cronbach's α coefficients. Results The instrument’s content validity index was 0.93. Exploratory factor analysis showed that the instrument version 3.0 comprised three main factors, 12 sub-factors and 46 items, which explained 67.4% of the total variance in the measured variable. The instrument’s internal consistency was high, with Cronbach’s α of 0.92. Conclusion The instrument showed acceptable psychometric properties and was suitable for measuring PHRR in women aged 18-65 years with breast cancer. The instrument provides multidimensional understanding of the PHRR of women with breast cancer. The PHRR instrument can be used to achieve a comprehensive understanding of the personal health-related resources for women with breast cancer during cancer care. This instrument can provide information how to support women and development psychosocial support in different phases of illness.
