Area of Science:

  • Maternal Health
  • Nutrition Science
  • Psychometrics

Background:

  • Dietary intake during pregnancy is critical for maternal and fetal health.
  • Barriers to healthy eating can increase the risk of pregnancy complications.
  • A validated instrument is needed to assess these barriers.

Purpose of the Study:

  • To assess the psychometric properties of the Barriers to Healthy Eating Scale.
  • To determine the reliability and validity of the scale in pregnant women.
  • To identify factors impeding healthy dietary intake in this population.

Main Methods:

  • Methodological study involving item generation based on Pender's health promotion model.
  • Instrument testing in two independent samples of pregnant women.
  • Content and construct validity assessments, including factor analysis and reliability testing (Cronbach's alpha, test-retest).

Main Results:

  • The Barriers to Healthy Eating Scale demonstrated good reliability (alpha coefficients .73–.77, test-retest .79).
  • Construct validity was supported by an expected negative correlation with a health promotion lifestyle subscale.
  • Factor analysis identified a 5-factor structure explaining 73% of the variance.

Conclusions:

  • The Barriers to Healthy Eating Scale is a reliable and valid instrument.
  • It can effectively assess impediments to healthy eating in pregnant women.
  • Findings can inform interventions to improve maternal nutrition and reduce complication risks.
