Experimental: Parent-Implemented Communication Intervention (PICT)
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).

- Caregiver Use of Communication Support Strategies [ Time Frame: Change in monthly samples between pre and post when the child is 12 to 18 months (during intervention) ]Caregiver use of communication support strategies is measured from a 10-minute caregiver-child interaction in which the dyad plays using a standard set of toys. This interaction will be video recorded and coded for their use of communication support strategies to yield the following variables: percentage of adult communication that is within the child's line of sight, percentage of adult communication that is paired with a gesture in the child's line of sight, percentage of child communication that is followed by a contingent response, percentage of adult communication that is in response to child communication, percentage of adult communication that contains a child linguistic target, and percentage of child communication to which the adult imitates and adds a word. These variables will be combined using confirmatory factor analysis to create a single latent variable.
- Total number of pre-symbolic communicative acts from the Language Sample [ Time Frame: Change in monthly samples between pre and post when the child is 12 to 18 months (during intervention) ]The child plays with four different sets of toys and looks at a wordless picture book for 20 minutes, while the assessor engages with the child but does not talk. Then a research assistant transcribes and codes all child communicative behavior.
- Total Scaled Score on the Communication and Symbolic Behavior Scales - Developmental Profile [ Time Frame: Post (immediately after intervention when the child is 18 months) ]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). An overall total scaled score is calculated based on the raw score and the child's age (min = 65; max = 135). Higher scores indicate better skills.
- Caregiver Use of Communication Support Strategies [ Time Frame: Monthly, up to 18 months, between post and follow-up when the child is 18 to 36 months (after intervention) ]Caregiver use of communication support strategies will be measured from a 10-minute caregiver-child interaction in which the caregiver plays with the child using a standard set of toys. This interaction will be coded for their use of communication support strategies to yield the following variables: percentage of intervals in which the adult is communicating within the child's line of sight, percentage of adult communication that is paired with a gesture in the child's line of sight, percentage of intervals in which the adult's play is related to the child, percentage of child non-verbal actions that are imitated, percentage of child communication that is followed by a contingent response, percentage of adult communication that is in response to child communication, percentage of adult communication that contains a child linguistic target, percentage of child communication to which the adult imitates and adds a word. These variables will be combined to create a single latent variable.
- Child Spoken Words [ Time Frame: Monthly, up to 18 months, between post and follow-up when the child is 18 to 36 months (after intervention) ]Total number of spoken words will be collected using two measures that will be combined used confirmatory factory analysis. Total Number of Words Said from the MacArthur-Bates Communicative Development Inventory: Words and Sentences and the total number of different spoken word roots from a 20-minute language sample in which an assessor plays with the child following a standardized protocol.
- Expressive Communication Standard Score on the Preschool Language Scale - 5th Edition [ Time Frame: Follow up (18 months after the study start when child is 36 months) ]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.
- Auditory Comprehension Standard Score on the Preschool Language Scale - 5th Edition [ Time Frame: Follow up (18 months after the study start when child is 36 months) ]The child is presented with different expressive tasks, such as labeling 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 Scores indicate better outcomes.
