Detailed Description
This study was a nonrandomized, controlled trial to determine whether a series of 6 weekly parent-child vegetable cooking skills classes and parent-led strategies informed by behavioral economics (1/week) (intervention group) improved dietary and non-dietary outcomes of a racially and ethnically diverse sample of low-income children (ages 9-12) more than a vegetable cooking skills program alone (control group).

Intervention / Treatment |
---|---|
EXPERIMENTAL: Intervention
The intervention consisted of an enhanced Cooking Matters® for Families program that included behavioral strategies derived from behavioral economics, to be implemented by parents at home for increasing vegetable intake of low-income 9-12 year old children
|
Intervention parents participated in an additional 20-25-min segment led by the nutrition educator during which the week's behavioral strategy was introduced.
The following six behavioral strategies were introduced (one each week) as a segment of each cooking skills session: 1) have your child help prepare vegetables for meals (Child Help), 2) use a plate that shows the amount of vegetables to include for a meal (My Plate), 3) make vegetables visible and accessible by removing other foods from the dining area during the meal and leaving the vegetables (Make Avail/Visible), 4) serve at least 2 vegetables with the meal (Serve 2), 5) serve vegetables before the meal (Serve First), and 6) use a bigger spoon to serve the vegetables (Big Spoon).
|
NO_INTERVENTION: Control
The control arm consisted of the enhanced Cooking Matters® for Families program alone--without lessons about the behavioral strategies for the parents

Child cooking skills self-efficacy was measured using scales that have shown internal consistency and test-retest reliability in a psychometric evaluation of a cooking-based nutrition education intervention among low-income 9-11 year old children (Cronbach α = ≥ 0.74, test-retest r ≥ 0.66).(Lohse

Response options for the child self-efficacy questions: 1 = YES! - 5 = NO!).
The child-self-efficacy scale was calculated by summing 8 items measuring self-efficacy.
A lower score indicated greater self-efficacy and more positive attitudes toward cooking.

Parents completed the Cooking Matters for Families Before and After Course Survey to assess change in cooking skills confidence.
Internal consistency and ability of the scales to reflect positive self-reported changes were previously among low-income adults (Pinard CA, Uvena LM, Quam JB, Smith TM, Yaroch AL.

Response options for the 4 cooking confidence questions: (4 items, 1 = not at all confident - 5 = very confident).
An aggregate score for each parent was tabulated by averaging the 4 questions.
A higher score indicated greater cooking skills confidence.
