Validity and Reliability Study of the Turkish Adaptation of the Reproductive Concerns After Cancer Scale

This methodological study aimed to evaluate the validity and reliability of the Turkish version of the Reproductive Concerns After Cancer Scale.

The study included 301 women aged 18-45 diagnosed with cancer in Izmir, Turkey. The language validity was established through the translation-back-translation. Construct validity was assessed via exploratory factor analysis and confirmatory factor analysis. Reliability was evaluated using internal consistency coefficients and test-retest analysis.

The Content Validity Index was 0.90. Exploratory factor analysis identified a four-factor structure explaining 67.88% of the total variance (KMO = 0.87, p < 0.001). Confirmatory factor analysis confirmed this structure with acceptable fit indices (X²/df = 3.34, RMSEA = 0.07, CFI = 0.90). The total Cronbach's alpha was 0.88, with subscales ranging from 0.75 to 0.90. Test-retest reliability was high (ICC = 0.99). Item-total correlations ranged from 0.31 to 0.72.

The Turkish version of the Reproductive Concerns After Cancer Scale is a valid and reliable 18-item tool. Oncology nurses can utilize this scale to effectively assess reproductive concerns in women of reproductive age, guiding counselling and supportive care interventions.
