Staff will maintain logs of the number of families who express interest in the study and of those, the number who qualify and enroll in the study

Staff will maintain logs of when a family completes each phase of the study, including pre-intervention data collection, the online program sessions, and data collection immediately after completing the intervention. Family completion is defined as both parent and child completion of a phase.

The 10-item measure has been used by Dr. Thompson in previous studies with children and adults. Items will be rated using a 2-point Likert scale (no=1, yes=2). Scores can range from 10-20, with higher scores representing higher satisfaction

The survey will be adapted from the Treatment Self-Regulation Motivation Questionnaire-diet which has demonstrated strong construct validity. This is a 15-item questionnaire that uses a 7 point Likert scale, ranging from 1, not at all true, to 7, very true. The scale was designed to be adapted for different behaviors and situations. The scale measures regulatory style and has three subscales, ranging from amotivation, controlled motivation, autonomous motivation.

The 13-item self-efficacy scale of the Cooking and Food Provisioning Action Scale will be adapted to assess parent self-efficacy for involving their child in home food preparation. The scale uses a 7-point Likert response scale ranging from strongly disagree to strongly agree.

The Competence/Self-Efficacy for Vegetable Food Parenting Practices is an 18-item scale scored using a three category response scale - disagree=1, neither agree nor disagree=2, agree=3. Responses are summed, with higher scores indicating higher self-efficacy.

This inventory is a 51 item checklist (yes=1, no=0) that assesses healthful and less healthful food available in the home. Foods are grouped into 13 major food groups and 2 categories of ready-access foods. Scores are summed, with higher scores indicating greater availability. The scale has demonstrated criterion and construct validity.

Parents will report child involvement in home food preparation using the question Larsen et al used in Project EAT "In the past week, how many times did your child help prepare food (meals, snacks) for your family".

The child will participate in 2, 24 hour dietitian-assisted recalls at each data collection time point. Diet will be assessed using a laptop computer, Nutrition Data System for Research software, and 2 dimensional food and measurement images. One weekday and one weekend day will be collected.

Parents will complete the validated online food parenting practice item bank which is based on an expert-informed conceptual framework assessing food parenting practices within three key domains of food parenting practices (autonomy promotion, control, and structure). Parents respond to each item using a 5 point response scale, ranging from never to 5-7 times a week. Responses are averaged to create a construct score, with higher scores indicating higher endorsement.

The Harvard semi-quantitative food frequency questionnaire includes 126 items. The Rumawas et al method will be used to compute the Mediterranean Diet Index

Prior to and after participation in the online intervention, parents will wear a recording device for 3 days during food preparation events and meals to obtain an objective measure of parent use of food parenting practices. Recordings will be reviewed to assess food parenting practices used during the time of wearing. Food parenting practice use will be rated as yes/no

A trained research coordinator will remotely view parent assessment of child height in inches using a professional grade measuring tape provided by the research team. Parents will assess child height in inches twice. If the measurement differs by more than .5 inches, a third assessment will be taken. Measures will be separated by 1-3 minutes.

A trained research coordinator will remotely view parent self-assessment of height in inches using a professional grade measuring tape provided by the research team. Parents will self-assess height in inches twice. If the measurement differs by more than .5 inches, a third assessment will be taken. Measures will be separated by 1-3 minutes.

A trained research coordinator will remotely view parent assessment of child weight in pounds using professional grade digital scales provided by the research team. Parents will assess child weight in pounds twice. If the measurement differs by more than .5 pounds, a third assessment will be taken. Measures will be separated by 1-3 minutes.

A trained research coordinator will remotely view parent assessment of child blood pressure in mmHg using a professional grade digital blood pressure monitor provided by the research team. Parents will assess child blood pressure twice. If the measurements of systolic or diastolic blood pressure differ by more than 2 mmHg, a third assessment will be taken. Measures will be separated by 1-3 minutes.

parents will complete a standard survey assessing demographic and household characteristics

Parents will complete the 18-item United States Department of Agriculture household food security questionnaire. The survey contains a series of questions about conditions and behaviors occurring during the past 12 months. The questionnaire identifies households that are having difficulty meeting basic food needs. The questionnaire contains 3 questions about household food conditions, 7 questions about food conditions of adults in the household, and 8 questions about child food conditions. Responses enable categorization of the household on food security status.

Parents will complete a checklist of household/adult participation in programs such as the Supplemental Nutrition Assistance Program, Women, Infants, and Children program and other federal programs designed to provide assistance to families in need. Responses will be used to characterize the home food environment.
