Study Description

Brief Summary:

Recent research reveals genetic and symptomatic overlap among children with speech sound disorders (i.e., those who (misarticulate more sounds than would be expected for their age) and children with dyslexia (i.e., those who struggle to learn to read). Children who have speech sound disorders as preschoolers are at risk for the later emergence of dyslexia, a risk that often reveals itself in the form of poor phonological awareness skills during the preschool period. Traditional speech therapy methods focus on articulation accuracy and do not focus on the child's more abstract knowledge of the sound system of the language. The ultimate objective of this research program is to prevent reading disability in children who present with speech sounds disorders. The relative effectiveness of different interventions to help these children achieve age-appropriate phonological processing skills prior to school entry will be investigated. It is expected that a combination of treatment approaches that focus on speech perception skills and vocabulary knowledge will have a superior impact on phonological awareness in comparison with a treatment approach that focuses solely on articulation accuracy.

Detailed Description:

The 72 children participating in the study will be randomly assigned (with concealment of the randomization sequence from study staff) to one of two Child Speech Interventions: Speech Perception or Speech Production. These interventions will be provided in individualized one-hour treatment sessions once per week for six consecutive weeks during the first treatment block. During the second 6 week treatment block all children will receive a group phonological awareness intervention. Concurrently their parents will be randomly assigned to receive instruction in the provision of a home program, either Articulation Therapy or Dialogic Reading. This will result in 4 groups of 18 children with each group receiving one of four combinations of intervention: Speech Production Intervention + Articulation Parent Group; Speech Production Intervention + Dialogic Reading Parent Group; Speech Perception Intervention + Articulation Parent Group; and Speech Perception Intervention + Dialogic Reading Parent Group. Assessments will occur pretreatment, after the first treatment block, after the second treatment block, and 9 months after the end of the second treatment block.

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: 1 Speech Production Intervention + Articulation Parent Group	Behavioral: Speech Production Intervention Individual speech therapy directed at teaching the child to articulation specific speech sounds or word shapes accurately using traditional procedures such as phonetic placement and imitated and spontaneous speech production practice with feedback from the clinician about accuracy of articulatory gestures and knowledge of results. Other Name: Articulation therapy Behavioral: Articulation Parent Group Parents are taught to carry out home practice activities that focus on the child's ability to correctly articulate target speech sounds and word shapes.
Experimental: 2 Speech Production Intervention + Dialogic Reading Parent Group	Behavioral: Speech Production Intervention Individual speech therapy directed at teaching the child to articulation specific speech sounds or word shapes accurately using traditional procedures such as phonetic placement and imitated and spontaneous speech production practice with feedback from the clinician about accuracy of articulatory gestures and knowledge of results. Other Name: Articulation therapy Behavioral: Dialogic Reading Parent Group Parents are taught to read to their children using interactive techniques that help their children acquire new vocabulary, verbal reasoning abilities, and preliteracy skills.
Experimental: 3 Speech Perception Intervention + Articulation Parent Group	Behavioral: Speech Perception Intervention Individualized intervention in which the Speech Assessment and Interactive Learning System is used to teach the child to identify recordings of words as either correct or incorrect pronunciations of the target word. In the event that the child is completely unable to pronounce the target speech sounds or word shapes focused stimulation activities are used to provide the child with further auditory exposure to the target forms. If the child stimulable for the target forms, the child is given opportunities the produce the target speech sounds or word shapes in the context of minimal pair games in which the child receives feedback about the communicative effectiveness of his or her attempts to produce the target words. Behavioral: Articulation Parent Group Parents are taught to carry out home practice activities that focus on the child's ability to correctly articulate target speech sounds and word shapes.
Experimental: 4 Speech Perception Intervention + Dialogical Reading Parent Group	Behavioral: Speech Perception Intervention Individualized intervention in which the Speech Assessment and Interactive Learning System is used to teach the child to identify recordings of words as either correct or incorrect pronunciations of the target word. In the event that the child is completely unable to pronounce the target speech sounds or word shapes focused stimulation activities are used to provide the child with further auditory exposure to the target forms. If the child stimulable for the target forms, the child is given opportunities the produce the target speech sounds or word shapes in the context of minimal pair games in which the child receives feedback about the communicative effectiveness of his or her attempts to produce the target words. Behavioral: Dialogic Reading Parent Group Parents are taught to read to their children using interactive techniques that help their children acquire new vocabulary, verbal reasoning abilities, and preliteracy skills.
