Brophy‐Herb 2017

Trial name or title	Simply Dinner Study
Methods	Multiphase Optimization Strategy (MOST), where the main, additive and interactive effects of 6 support strategies are first tested in a screening phase to identify the intervention components most robustly associated with increased family meals and improvements in dietary quality. The MOST factorial design includes 6 intervention components with a Usual Head Start Exposure condition (usual‐care control); thus, individual participants are randomised to one of 64 experimental conditions. The 64 experimental conditions result from the crossing of 6 Simply Dinner intervention components, each of which has 2 conditions (present vs. not), and reflect all possible pairings of the intervention components, including a no‐intervention condition. These components are then tested in the confirming phase via RCT.

Interventions	6 intervention components ranging from the most to least intense forms of support Meal delivery‐ MD: home delivery of pre‐made healthy family meals including recipes that are ready to heat and eat; Ingredient delivery‐ ID: home delivery of ingredients with recipes to make and cook healthy family meals; Community kitchen‐ CK: sessions in which families make healthy meals with recipes to take home and cook; Didactics healthy eating classes with recipes via the Parents of Preschoolers‐ POPS curriculum; Cooking demonstration‐ CD: demonstration of meal preparation with recipes; and Cookware/flatware: delivery of flatware/cookware to utilise for family meals
