Abstract

Purpose

This study was designed to develop a valid and reliable scale for the evaluation of preconception health behavior in women preparing for pregnancy.

Methods

The initial strategy included a literature review, interviews, and construction of a conceptual framework. The preliminary items were evaluated twice for content validity by experts, and modified two preliminary investigations. Participants in the 2 main investigations and the confirmation investigation were tested for reliability and validity of the preliminary scale in women preparing for pregnancy. The data were analyzed for different items exploratory and confirmatory factors.

Results

The 5-point Likert scale consisted of 6 factors and 27 items. The 6-factors included ‘hazardous substance factor,’ ‘medical management factor,’ ‘rest and sleep factor,’ ‘stress management factor,’ ‘information acquisition factor,’ and ‘resource preparation factor.’ Goodness of fit of the final research model was very appropriate and based on the following measures: Q=1.98, comparative fit index=.91, Tucker-lewis index=.89, standardized root mean square residual=.07, and root mean square error of approximation=.07. The criterion validity was .64. The reliability coefficient was .92 and the test-retest reliability was .61.

Conclusion

The study findings indicate that the scale can be used for the development of nursing interventions to promote preconception health behavior in women preparing for pregnancy.
