Development of an infertility perception scale for women (IPS-W)

The purpose of this study was to develop an Infertility Perception Scale for Women (IPS-W).

Initial items were based on an extensive literature review and in-depth interviews with five infertile women and fifteen women not diagnosed with infertility. Forty-one items were derived from a pilot survey. Data were collected from 203 women who had experienced intrauterine insemination (IUI) and in-vitro fertilization (IVF) more than once. The data were analyzed to verify the reliability and validity of the scale.

Four factors containing 21 items were extracted from the exploratory factor analysis (EFA) to verify the construct validity. The four factors of infertility perception scale were perceived feelings, personal stigma, social stigma, and acceptance. These factors explained 59.3% of the total variance. The confirmatory factor analysis (CFA) confirmed a four-factor structure of the 21-item IPS-W. All fit indices were satisfactory (χ²/df ≤ 3, RMSEA < 0.08). These items were verified through convergent, discriminant, known group validity, concurrent validity testing. The internal consistency reliability was acceptable (Cronbach's α = 0.90).

The scale reflects the perception of infertility within the cultural context of Korea. The findings can help nurses provide support that is appropriate for individual circumstances by examining how women experiencing infertility perceive infertility.
