Fertility Intention Scale in Breast Cancer Survivors: Turkish Validity and Reliability Study

This study aimed to adapt the fertility intention scale (FIS) for Breast Cancer Survivors into Turkish and assess its validity and reliability.

The study sample consisted of 157 women of reproductive age who had completed chemotherapy and radiotherapy for breast cancer. The Turkish version of the scale was developed using the translate-back translation method for language validity. Expert opinions were sought for content validity, and the content validity index was calculated. For construct validity, confirmatory factor analysis was performed using Structural Equation Modeling in Amos 23.0. Reliability was assessed through Cronbach's alpha, Pearson correlation for scale dimensions, and intraclass correlation coefficient for test-retest reliability, with P < .05 considered significant.

The reliability coefficients for the total FIS and its four subdimensions ranged from 0.77 to 0.97. Intraclass correlation coefficient analysis showed a significant fit (0.87-0.97) between test-retest measurements for the FIS and its subdimensions. Pearson correlation revealed a significant positive relationship between the FIS and the Post-traumatic Growth Inventory (r = 0.238, P < .001). Exploratory factor analysis confirmed the scale's four subdimensions: "Pregnancy risk," "Disease control," "Social support," and "Happiness."

As a result, the 15-item scale and four factors were found to be theoretically and statistically acceptable. The FIS for Breast Cancer Survivors is a valid and reliable measurement tool.

The FIS can help nurses assess breast cancer survivors' fertility concerns, enabling them to provide personalized counseling and support related to reproductive health options.
