Trial Outcomes & Findings for Early Communication Intervention for Toddlers With Hearing Loss (NCT NCT03803943)
NCT ID: NCT03803943
Last Updated: 2025-10-15
Results Overview
Parent use of communication support strategies was measured from a 12-minute parent-child interaction in which the dyad plays using a standard set of toys. Interactions were video recorded and coded for 13 items representing subcomponents of seven communication support strategies. Each item was rated on a 5-point scale (1 = novice use, 5 = expert use), reflecting the quality and proficiency of parent strategy use. Items were averaged to yield a Total Composite Score (Min = 1, Max = 5), with higher scores indicating more proficient and consistent use of communication strategies.

Participant Flow
Randomization occurred at the dyad level, with each dyad consisting of one parent and one child. The dyad was considered the enrolled unit in the study, and each dyad was randomly assigned to either the intervention or control group. The arm/group title is labeled based on the dyad's assignment and reflects the joint participation of both caregiver and child.

Parent-Implemented Communication Intervention (PICT) - Children
Participants assigned to the PICT condition will receive weekly hour long intervention sessions in their home for 6 months. Parents will learn four sets of communication support strategies: (a) visual (e.g., modeling language within the child's line of sight), (b) interactive (e.g., following the child's attentional focus), (c) responsive (e.g., responding to all communicative attempts), and (d) linguistically stimulating (e.g., modeling language targets, expanding child communication).

PRIMARY outcome
Timeframe: Change from Baseline to Month 7Population: This is an outcome measure of the parent participants only.
Parent use of communication support strategies was measured from a 12-minute parent-child interaction in which the dyad plays using a standard set of toys. Interactions were video recorded and coded for 13 items representing subcomponents of seven communication support strategies. Each item was rated on a 5-point scale (1 = novice use, 5 = expert use), reflecting the quality and proficiency of parent strategy use. Items were averaged to yield a Total Composite Score (Min = 1, Max = 5), with higher scores indicating more proficient and consistent use of communication strategies.

Participants assigned to the PICT condition will receive weekly hour long intervention sessions in their home for 6 months. Parents will learn four sets of communication support strategies: (a) visual (e.g., modeling language within the child's line of sight), (b) interactive (e.g., following the child's attentional focus), (c) responsive (e.g., responding to all communicative attempts), and (d) linguistically stimulating (e.g., modeling language targets, expanding child communication).

PRIMARY outcome
Timeframe: Change from Baseline to Month 7Population: This is an outcome measure of the child participants only.
During the 10-minute interaction, the child played with toys and wordless picture books. A research assistant transcribed and coded all communicative acts. Each communicative act was assigned a weight reflecting its developmental complexity: gestures and vocalizations = 1 point, single words = 2 points, and multiple-word utterances = 3 points. The Total Weighted Frequency Score (Min = 0, Max = NA) is the sum of the weighted frequency of each act, with higher scores reflecting more frequent and complex communicative acts.

PRIMARY outcome
Timeframe: Month 7Population: This is an outcome measure of the child participants only.
The child is presented with 6 different activities (wind-up toy, balloon, bubbles, jar, books, play) designed to elicit child communication. The interaction is video recorded and then scored for 20 items across 7 communication scales (emotion and eye gaze, communication, gestures, sounds, words, understanding, and object use). The weighted raw scores for each of the 7 scales were grouped into 3 clusters (social, speech, and symbolic) and combined into a total raw score (min = 0; max = 113). Higher scores indicate better skills.

The child is presented with different receptive tasks, such as following simple directions and pointing to pictures, until the child provides an incorrect response to six consecutive items. A total standard score is calculated based on the raw score and the child's age (min = 50; max = 150). Higher score indicate better outcomes.
