Abstract
Objective
To assess the validity of 5 parental stage-of-change (SOC) measures: (1) providing
5 servings/d of fruits and vegetables (FV), (2) limiting television (TV) to 2 h/d,
(3) helping children achieve 1 h/d physical activity (PA), (4) limiting sugary drinks
(SD) to 1 serving/wk, and (5) limiting fruit juice (FJ) to 4–6 oz/d.
Design
Cross-sectional instrument development study. Construct validity was evaluated by
examining whether parental self-efficacy, parental readiness ladder (ladder), and
child's behavioral levels (eg, FV consumption) exhibited a theoretically consistent
pattern across the SOC.
Setting/Participants
Convenience sample (n = 283) of parents of children aged 4–10 years.
Measures
Survey assessed SOC, ladder, and child's behavioral level score for each topic (FV,
TV, PA, SD, and FJ), and parental self-efficacy for measure except TV.
Analysis
Analysis of variance with Tukey–Kramer post hoc tests examined whether variables differed by SOC.
Results
Percentages of parents in the pre-action SOC were 34% (PA), 39% (FV), 42% (SD), 45%
(TV), and 63% (FJ). Parental self-efficacy, ladder, and child's behavioral level differed
significantly by SOC for each topic area (P < .001). Maintenance SOC was significantly higher than pre-action SOC.
Conclusions and Implications
Measured variables exhibited a theoretically consistent pattern across SOC, suggesting
construct validity and potential usefulness for obesity prevention efforts.
