Reliability and validity of the Chinese version of the COMPI Fertility Problem Stress Scale-Short Form for infertile...

To translate and culturally adapt the COMPI Fertility Problem Stress Scale-Short form (COMPI-FPSS-SF) and to test its reliability and validity in China.

The cross-sectional study adopted Brislin's translation model to translate, synthesize, back-translate, and cross-culturally adapt the COMPI-FPSS-SF for the Chinese setting. A total of 279 infertile women were invited to participate in the study to test the reliability and validity of the scale between March and June 2021.

It was verified that the Chinese version of the COMPI-FPSS-SF has three domains with nine items. The Cronbach's α coefficient of the total scale was 0.907, and the coefficient for each dimension ranged from 0.760 to 0.855. The test-retest validity was 0.891. The exploratory factor analysis extracted three common factors with eigenvalues of 4.499, 1.124, and 1.011 and a cumulative variance contribution of 73.706. The validity factor analysis showed good results for the three-factor structure fit. The criterion-related validity with the Fertility Inventory Short-Form Scale was 0.649. The above analysis revealed statistically significant differences (P < 0.001).

The Chinese version of the COMPI-FPSS-SF can be used for the assessment of fertility-related stress in infertility patients in China with good reliability and validity.
