Study summary

This study is being done to examine the feasibility and impact of the Infant Achievements caregiver coaching treatment on caregiver child-engagement strategies used during play with their infant. The investigators will examine effects on infants' social and communication behavior. This randomized controlled trial will compare caregivers and infants in the Infant Achievements (IA) coaching group to caregivers and infants in the Caregiver Education (CE) no-coaching group. A total of 64 eligible participants (16 children plus their caregiver per group) will participate in the study.

Read the detailed description

This study is being done to examine the feasibility and impact of the Infant Achievements caregiver coaching treatment on caregiver child-engagement strategies used during play with their infant. The investigators will examine effects on infants' social and communication behavior. This randomized controlled trial will compare caregivers and infants in the Infant Achievements (IA) coaching group to caregivers and infants in the Caregiver Education (CE) no-coaching group. A total of 64 eligible participants (16 children plus their caregiver per group) will participate in the study. Parents in the IA group will be coached, at home twice a week, to implement the intervention by trained research staff. Parents in the CE group will be taught about child development and well-being in their home, weekly, with a weekly follow-up phone call by trained research staff. In both groups: Videotaped caregiver-child interaction data will be gathered in the home. Baseline, post-treatment and follow-up measures will also be collected at the investigators' child development research center.

Families with children between the ages of 8 and 12 months with developmental concerns may be eligible to participate. Developmental concerns are defined as infrequent production of specific communication or social behaviors, or in immature or qualitatively atypical forms. These concerns will be documented via the Autism Observation Scale for Infants, Communication and Symbolic Behavior Scale (CSBS) Infant-Toddler Checklist, and/or Mullen Scales of Early Learning. Recruitment will occur from the Kennedy Krieger Institute (KKI), community agencies, and community events. Recruitment flyers will be distributed within those programs. In addition, a social media blurb will be placed on the KKI and other relevant groups' Facebook pages, KKI Center for Autism and Related Disorders newsletter, KKI websites, and may be sent to relevant local newsletters/magazines for families of young children.

Study arms

  • Experimental
    Infant Achievements

    Families randomized to the IA condition will receive 17 in-home sessions. These include a one-time start up session followed by twice-weekly visits in which they will be coached on how to implement the IA strategies. Families will receive a set of developmentally appropriate toys.

    Behavioral: Infant Achievements

  • Experimental
    Caregiver Education

    In this condition, parents will receive 17 sessions with a trained study team member focused on promoting child development and well-being. Sessions include a one-time start-up visit followed by one in-home visit and one phone contact per week. Families will receive a set of developmentally appropriate toys.

    Behavioral: Caregiver Education (CE)

Interventions

  • BehavioralInfant Achievements

    Play-based intervention for caregivers and infants. The efficacy of the Infant Achievements intervention for improving communication and social behavior in infants who are at risk for communication, social, or developmental delay.

  • BehavioralCaregiver Education (CE)

    Parents in the CE group will be taught about child development and well-being in their home, weekly, with a weekly follow-up phone call by trained research staff.

What researchers measure

Primary outcomes

  1. Change in parent behavior during the Parent-Child Play Sample

    This measure is a natural observation of parent and child unstructured playing, and will be used to assess change in caregiver's use of child-responsive engagement strategies

    Time frame: Change from behavior at Baseline to behavior at 8 weeks post-baseline, and from Baseline to 8 weeks post-intervention

  2. Change in child communication and social engagement sample during the Parent-Child Play Sample

    This outcome will be coded from the Parent-Child Play Sample

    Time frame: Change from behavior at Baseline to behavior at 8 weeks post-baseline, and from Baseline to 8 weeks post-intervention

Secondary outcomes

  1. Change in scores on the Mullen Scales of Early Learning Receptive and Expressive Language Raw Scores

    Receptive Language score (score range 0-48); Expressive Language Score (score range 0-50); higher scores indicate better outcome for both scales

    Time frame: Change from Baseline to 8 weeks post-baseline and from Baseline to 8 weeks post-intervention

  2. Change in scores on the MacArthur-Bates Communication Development Inventory

    Number of words understood (range 0-396); Number of words produced (0-396); Total actions \& gestures (0-63); higher scores indicate better outcomes for all scales

    Time frame: Change from Baseline to 8 weeks post-baseline and from Baseline to 8 weeks post-intervention

  3. Change in scores on the CSBS Behavior Sample

    Frequency of initiation of joint attention; frequency of communicative consonants (range 0-6), gestures (range 0-6) and words (range (0-6); higher scores indicate greater outcome on all scales

    Time frame: Change from Baseline to 8 weeks post-baseline and from Baseline to 8 weeks post-intervention
