Healthy Growth Abbreviated Pilot Study

Eksperimentel: Pilot Intervention Group

Mothers who are screened and determined to be eligible for this single-group pilot study will be enrolled along with their infants in the Grow Together peer group intervention.

Adfærdsmæssigt: Grow Together peer group

Participants in this intervention will:

• Participate in Facebook group of 6-10 peers for about 8 weeks, led by a professional group mentor.

• Complete an intervention video activity approximately weekly:

  • 1. View educational videos addressing topics related to healthy infant growth
  • 2. Create photos/videos modeling healthy behaviors and post them to the group
  • 3. Provide and receive feedback on posts
  • 4. Be encouraged to share information with key caregivers of their child
• Attend group party soon after enrollment, to meet peers and group leader in person.
• Receive text message reminders, 1) to schedule recommended primary care visits for their infant, and 2) to attend appointments scheduled in CHOP Care Network.
• Have basic program information provided to pediatrician to enhance conversation during office visits.

Intervention Acceptability Survey

Satisfaction with the overall intervention will be assessed for mothers using a standard survey. Subjects will be asked a series of open-ended and Likert-scaled questions.

Study population eligibility and interest

• Proportion of all mothers contacted who meet enrollment criteria
• Proportion of mothers meeting enrollment criteria who enroll

These proportions will be calculated using study recruitment records.

Participant engagement

• Proportion of enrolled mother-infant dyads that comply with intervention participation requirements
• Proportion of enrolled mother-infant dyads that complete each weekly module activity
• Proportion of enrolled mother-infant dyads that complete each study measure
• Number and type of each participant's Facebook group interactions per week (posts, comments, "Likes")
• Frequency, type, and content of each contact between moderator/study staff and each participant

This study process data will be obtained from the Facebook group and study records at study end.

Infant feeding beliefs

Maternal beliefs regarding infant feeding will be measured using the Infant Feeding Style Questionnaire (IFSQ), which contains 10 items measuring beliefs, coded on a 5-point scale (disagree, slightly disagree, neutral, slightly agree, agree).

Infant feeding practices

Maternal behaviors related to infant feeding will be measured using 10 items on the Infant Feeding Style Questionnaire (IFSQ). Behavior items are coded on a 5-point scale (never, seldom, half of the time, most of the time, always).

Also, four items from the validated Infant Feeding Practices Questionnaire (IFPQ) will be used to assess maternal feeding practices related to obesity. The IFPQ contains 20 items, with a 5-point adapted Likert response scale ranging from 0 (Never) to 4 (Always).

Breastfeeding survey

Breastfeeding intent, initiation, and duration will be assessed using a survey

Introduction of solid foods and sugar-sweetened beverages

Timing of initiation of solid foods and sugar sweetened beverages will be assessed using a survey.

Infant sleep behaviors

Infant sleeping and related maternal activities will be measured using the validated Brief Infant Sleep Questionnaire (BISQ). Subjects will complete the abbreviated 13-item BISQ (A-BISQ), as well as 2 additional questions from the expanded version (E-BISQ).

Parenting self-efficacy

The Karitane Parenting Confidence Scale (KPCS) is a 15-item validated scale that will be used to measure parenting self-efficacy. Questions assess the frequency of certain beliefs, skills and abilities related to successful parenting, measured using a 4-point response structure (No, hardly ever; No, not very often; Yes, some of the time; Yes, most of the time).

Positive parenting behaviors

Mothers will be assessed regarding specific parenting practices using the 10-item Infant/Toddler (IT) Home Observation for Measurement of the Environment (HOME) Inventory. Individual responses for each yes/no item are coded to 0 or 1.

Maternal self-care behaviors

Mothers will be asked 11 questions related to their self-care behaviors, including their own sleep habits, support-seeking behaviors, and taking time for themselves. These items are a combination of Likert-scaled items and simple measures of the frequency of behaviors.

Maternal social support

Mothers' level of social support will be assessed using the Multidimensional Scale of Perceived Social Support (MSPSS). This validated scale is made up of 12 items. Responses for this scale are coded from 1 to 7 (very strongly disagree, strongly disagree, mildly disagree, neutral, mildly agree, strongly agree, and very strongly agree).

Maternal stress

The Parental Stress Scale (PSS) is a validated, 18-item public domain scale measuring perceived parental stress using a 5-point Likert rating scale ('Strongly disagree' to 'strongly agree').

Infant weight and growth

Infants' weight will be measured using using a calibrated digital scale and length will be measured using a standard infantometer. Measurements will be taken by a trained nurse or other trained staff member at the primary care recruitment sites, or by a member of the study staff trained in anthropometric measures.
