Effectiveness of DIR/Floortime™ in Children With Intellectual Developmental Disorder: A Randomized Controlled Trial

This randomized controlled trial aims to evaluate the effectiveness of Integrated Developmental, Individual-differences, Relationship-based (DIR)/Floortime™ intervention in improving functional emotional development and adaptive behavior in children with Intellectual Developmental Disorder (IDD). Participants aged 4-12 years will be randomly assigned to receive either DIR/Floortime™ in addition to standard therapy or standard therapy alone for 10 weeks. Outcomes will be assessed using the Functional Emotional Assessment Scale (FEAS) and the Vineland Adaptive Behavior Scales (VABS).

Detailed Description

Intellectual Developmental Disorder (IDD) is characterized by significant limitations in intellectual functioning and adaptive behavior, affecting conceptual, social, and practical skills. Although conventional therapeutic interventions support developmental progress, many children continue to experience challenges in communication, social interaction, daily living skills, and functional emotional development. The Developmental, Individual-differences, Relationship-based (DIR)/Floortime™ model is a relationship-based intervention designed to enhance emotional, social, and developmental capacities through child-led interactions.

This study is a parallel-group randomized controlled trial evaluating the effectiveness of Integrated DIR/Floortime™ in children with IDD. Participants aged 4-12 years will be randomly assigned to either an experimental group receiving DIR/Floortime™ in addition to standard therapy or a control group receiving standard therapy alone. The intervention will be delivered over a period of 10 weeks.

The primary outcomes include communication, socialization, daily living skills, and functional emotional development. These outcomes will be measured using the Vineland Adaptive Behavior Scales (VABS) and the Functional Emotional Assessment Scale (FEAS) at baseline and after completion of the 10-week intervention. The findings will contribute to the evidence regarding the effectiveness of DIR/Floortime™ for children with Intellectual Developmental Disorder.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Socialization Skills
Time Frame: Baseline and Week 10
Change in Socialization Skills measured using the Vineland Adaptive Behavior Scales, Third Edition (VABS-3), Socialization domain Growth Scale Values (GSVs). GSVs range from 10 to 197, with higher scores indicating better adaptive functioning.
Baseline and Week 10
Communication Skills
Time Frame: Baseline and Week 10
Change in Communication Skills measured using the Vineland Adaptive Behavior Scales, Third Edition (VABS-3), Communication domain Growth Scale Values (GSVs). GSVs range from 10 to 197, with higher scores indicating better adaptive functioning.
Baseline and Week 10
Daily Living Skills
Time Frame: Baseline and Week 10
Change in Daily Living Skills measured using the Vineland Adaptive Behavior Scales, Third Edition (VABS-3), Daily Living Skills domain Growth Scale Values (GSVs). GSVs range from 10 to 197, with higher scores indicating better adaptive functioning.
Baseline and Week 10
Functional Emotional Development
Time Frame: Baseline and Week 10
Change in functional emotional development measured using the Functional Emotional Assessment Scale (FEAS). FEAS items are scored from 0 to 2, with higher scores indicating better functional emotional development. Symbolic, Sensory, and Examiner scores are assessed.
Baseline and Week 10
