Purpose: The purpose of this study was to develop an uncertainty scale for infertile women. Methods: The process
included construction of a conceptual framework, generation of 12items, verification of content validity, selection of
secondary items, verification of construct validity and extraction of final items. In order to verify the reliability and
validity of the preliminary instrument, data were collected from 50 infertile women in an In Vitro Fertilization (IVF)
clinic. Data were analyzed by item analysis, Varimax factor analysis and Cronbach's alpha. Results: There were 10
items in the final instrument categorized into 2 factors labeled as "personal (6 items)" and "relational (4 items)" The
total variance explained was 73.36%. The instrument was shown to have good reliability with a Cronbach’s alpha
of .899. Conclusion: Validity and reliability of the scale were confirmed in this study showing its utility to measure
uncertainty for infertile women. The instrument can help understand sterility and accurately measure uncertainty for
infertile women. The instrument can also be used to evaluate nursing interventions designed for mitigating uncertainty
for infertile women.
