New Questionnaire Validated to Assess Parental Influence on Children's Fruit and Vegetable Intake

A new study has successfully developed and validated a questionnaire designed to evaluate parental practices regarding their children's fruit and vegetable (FV) consumption. This new tool offers a standardized way to measure behaviors crucial for healthy eating habits in early childhood.

Background

Most American children do not meet recommended daily fruit and vegetable intake targets, a deficiency that impacts long-term health and contributes to food waste. Early childhood is a critical period for establishing dietary preferences.

Parental behaviors significantly influence children's early taste preferences and habits, including making FV available, encouraging consumption, and repeated exposure to various tastes.

Despite this importance, there has been a notable lack of validated tools specifically designed to measure FV-promoting parental practices in early childhood, especially those that are culturally inclusive.

Study Design

Researchers conducted a rigorous three-phase study, utilizing data from a larger project focused on parental FV practices. The primary goal was to develop and rigorously test a new measure of FV parenting practices within a racially/ethnically diverse, low-income sample of preschool children enrolled in Head Start programs.

  • Phase 1: Researchers identified key areas of parental practices from existing measures, initially generating a comprehensive 107-item questionnaire.
  • Phase 2: This extensive item list was subsequently revised using valuable insights gathered from 18 focus groups involving 62 parents (predominantly mothers) of preschoolers.
  • Phase 3: A significantly reduced, 21-item questionnaire was administered to 281 newly recruited parents of 3-5-year-old children. This diverse participant group was mostly mothers (mean age of 31.9 years) and comprised approximately 38% Black, 36% Hispanic White, and 27% White individuals.

Key Findings

The 21-item questionnaire underwent refinement and was ultimately structured into four distinct subscales: availability, modeling, child-focused, and pressure. Each subscale demonstrated strong internal consistency, indicating its reliability in accurately measuring its intended concept.

Cultural Equivalence

The subscales largely exhibited configural and metric invariance across the studied cultural and racial-ethnic groups (Black, Hispanic, White). This crucial finding suggests that the questionnaire effectively captured similar underlying behaviors related to FV parenting across these diverse groups.

Differences Noted: An exception was observed within the child-focused subscale, where Hispanic parents differed from White parents on three of five items. Specifically, Hispanic parents focused more on having prepared FV readily available, while White parents emphasized including the child in food preparation.

Validity

The subscales showed significant correlations with other well-validated measures of parental feeding practices, such as the Child Feeding Questionnaire, and with children's reported fruit and vegetable intake over the previous week. Importantly, the questionnaire scores did not correlate with the child’s BMI, parental education, income, or age, suggesting its broad applicability across diverse socioeconomic samples.

Strengths and Limitations

Strengths

The study boasts several significant strengths:

  • The development of a brief, easily administered questionnaire suitable for diverse populations.
  • A rigorous multi-phase approach to item development and validation.
  • The use of a racially and socioeconomically diverse sample, enhancing its relevance.
  • The questionnaire's ability to explore parental practices for fruits and vegetables separately, offering more nuanced insights.

Limitations

Despite its strengths, the study acknowledges certain limitations:

  • The use of a convenience sample may introduce selection bias.
  • The limited generalizability of findings to other racial/ethnic groups beyond those specifically studied.
  • The questionnaire's temporal (test–retest) reliability was not assessed.
  • The cross-sectional design prevents conclusions about causality between parental practices and child FV consumption.

Conclusion

The initial validation analyses successfully established a new questionnaire for assessing parental behaviors related to children's fruit and vegetable consumption. This tool demonstrated initial validity and measurement equivalence across three distinct ethnic-racial groups.

Further research is highly recommended to confirm the questionnaire's reliability and to explore longitudinal associations in larger, more varied samples.
