Family Matters Intervention

"Families will participate in eight in-home education activities. The visits will focus on family meal quality (dietary, interpersonal) and quantity (meal frequency) factors found in prior studies to be associated with child weight and weight-related behaviors. Eight of the visits (every other week) will be delivered by a CHW and will last 90 minutes. Additionally, a family meal food preparation activity will occur to help support families in learning skills to increase family meal quality and quantity. On weeks opposite of the in-home education visits with a CHW, families will be given a Try it Yourself activity to reinforce the messages (e.g., use family meals as a family connection time) and skills (e.g., recipe that requires families to steam vegetables) taught by the CHW during the in-home education visits."

Parents will receive daily EMI messages regarding suggestions for increasing meal quality/quantity via a smartphone application, based on the stress level and source of stress they reported earlier in the day. Specifically, parents will receive two push notifications in the morning to report their stress level and type/source of stress (e.g., work, children, finances). Then, based on the reported stress level and source of stress, parents will be texted tips/ideas for carrying out a nutritionally and emotionally healthful family meal the same night, in the face of stress. If parents report no stress on their EMI measure earlier in the day, they will be provided with a menu of options regarding what type of meal tip they would prefer later in the day (e.g., recipe ideas, meal prep tips, mealtime conversation starters. Parents will be able to respond to the EMI messages indicating preferred tips so that EMI tips become more meaningful/relevant to the needs of each family.

Parents will video-record and upload via their cellphone one family meal every other week, which will be watched by intervention staff. Using Motivational Interviewing, CHWs will give specific feedback on how to adapt negative mealtime behaviors and provide reinforcement for positive behaviors seen in the videos, based on a validated interpersonal coding tool called the Iowa Family Interaction Rating Scales (IFIRS). Additionally, feedback will be given on the dietary healthfulness of the meal, based on a validated coding tool called the Healthfulness of Meal Index (HOM). After feedback, family members will be taught specific skills to improve their family meal processes and behaviors that vary from food preparation skills, to increasing healthful food options at meals, or role-playing family interactions to improve the emotional atmosphere at the meal. Families will also set SMART goals at each visit regarding family meal quality and quantity.

After 16 weeks, EMI family meal tips for all arms will be reduced to only the days in which parent's report their highest stress levels. Stress profiles will be created for each parent in order to tailor the EMI family meals tips to days in which they experience their highest levels of stress. For example, during the 16-weeks of EMI, a parent may report their highest stress levels on Tuesdays and Thursdays. The stress profile that would be created for the parent during the maintenance phase would include receiving text messages only on Tuesdays and Thursdays. The parent would then receive these EMI family meal tips only on Tuesdays and Thursdays throughout the 8-week maintenance phase..
