Study Description
Brief Summary:

Early connections has two broad goals:

  • to identify risk indices for autism spectrum disorder (ASD) in 6 to 24 month old infants who have an older sibling with ASD or infants who have an older neurotypical sibling.
  • to assess whether it is possible to alter risk processes through early intervention with high-risk infants, thereby reducing social-communication delays or the severity of autism symptoms.

Condition or disease Intervention/treatment
Autism Spectrum Disorder Behavioral: Assessment, Monitoring & Intervention

Detailed Description:

Researchers at the University of Washington want to learn more about the benefits of early monitoring and intervention for younger siblings of children with autism spectrum disorders (ASD). The information gained in this study may improve methods of early detection and intervention for infants who may be at risk for developing autism and lead to better outcome for these young children and their families.

Participants include families with a child who has been diagnosed with an autism spectrum disorder or typical development and a younger sibling 12 months old or younger. The study protocol includes: (1) comprehensive infant evaluations at the University of Washington Autism Center at 6-months, 12-months, 18-months and 24-months of age. (2) Developmental screening for the older sibling. (3) Questionnaires and phone interviews for parents. (4) Random assignment to an assessment and monitoring intervention group or a University of Washington intervention group. All families will receive advice regarding appropriate intervention services. Families who are assigned to the UW intervention will take part in a parent delivered intervention.

Arms and Interventions

Arm Intervention/treatment
No Intervention: Assessment & Monitoring
No Intervention. Parent-Child participants in assessment and monitoring visits but does not receive any study provided treatment.
Experimental: Assessment, Monitoring + Intervention
Parent-Child participants in assessment and monitoring visits but also the Promoting First Relationships PFR intervention (http://pfrprogram. Org). PFR is a 10 weekly 60-85 minute in-home visits by a masters level mental health provider trained in the PFR curriculum. The PFR curriculum focuses on increasing parenting sensitivity using attachment theory-informed, strength-based consultation strategies. The curriculum is fully manualized and fidelity was assessed according to the manual.
Behavioral: Assessment, Monitoring & Intervention
Assessment and monitoring at 6, 12, 18 and 24 months; Parent delivered intervention provided between 6 and 12 months.
Other Name: Promoting First Relationships
