Triadic gaze intervention for young children with physical disabilities

Area of Science:

• Developmental Psychology
• Pediatric Rehabilitation
• Communication Sciences

Background:

• Joint attention is crucial for social and cognitive development.
• Children with severe motor impairments often face challenges in developing coordinated joint attention.
• Triadic gaze (TG) serves as a vital behavioral indicator of coordinated joint attention.

Purpose of the Study:

• To evaluate the efficacy of a supplemental treatment aimed at teaching triadic gaze (TG).
• To determine if TG treatment significantly enhances TG in children with severe motor impairments compared to standard care.
• To assess TG as a behavioral manifestation of coordinated joint attention.

Main Methods:

• A randomized controlled study involving 18 children (10-24 months) with severe motor impairments.
• Participants were assigned to an experimental (TG treatment + standard practice) or control group (standard practice only).
• Treatment involved 29 sessions over 17 weeks, with masked coders assessing TG productions.

Main Results:

• Triadic gaze (TG) increased in both groups from baseline to final measurement.
• The experimental group exhibited a slightly greater increase in TG.
• Significant differences favoring the experimental group were observed at 12 weeks (medium effect) and at the end of the treatment phase (large effect).

Conclusions:

• The findings suggest that a focused, short-term treatment can effectively teach triadic gaze (TG).
• This intervention shows promise for improving coordinated joint attention in children with severe physical disabilities.
• TG treatment may serve as a valuable tool in pediatric rehabilitation for communication development.
