Age-related Correlates of Treatment for Late-acquired Sounds (ARC)

Age-related Correlates of Treatment Efficacy and Efficiency for Late-acquired Sounds

Late-acquired sounds, such as /r/ are difficult to learn and many children experience persistent errors on these sounds. The purpose of the present study is to determine whether treating these sounds earlier in the child's life may result in better outcomes.

Detailed Description

Late-acquired sounds, such as /r/ are difficult to learn and many children experience persistent errors on these sounds. However, these sounds are often treated later in a child's life because they are not expected to be fully acquired until quite late--age 7-8 for some sounds. This practice places treatment in a time of the child's development in which they struggle to learn new sounds.The purpose of the present study is to determine whether treating these sounds earlier in the child's life may result in better outcomes, and to examine treatment efficacy and efficiency for two methods of treatment.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Non-Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Motoric Arm
Children will participate in an intervention based on traditional articulation approaches to speech therapy.
children receive instruction in producing new sounds at the isolation, syllable and word level.
Active Comparator: Phonologic Arm
Children will receive intervention that targets the conceptual representation of sounds.
children receive instruction in producing new sounds at the word level

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Treatment Efficacy: Number of correct productions of treated speech sounds in treatment words
Time Frame: baseline until accuracy criterion is met; up to 18 weeks after final baseline session
Accurate Production of treatment sound at baseline and at posttest
baseline until accuracy criterion is met; up to 18 weeks after final baseline session
Treatment Efficiency: Number of sessions required to meet accuracy criteria
Time Frame: baseline until accuracy criterion is met; up to 18 weeks after final baseline session
Number of treatment sessions required to meet accuracy criteria (90% accuracy across three consecutive sessions or a maximum of 35 treatment sessions)
baseline until accuracy criterion is met; up to 18 weeks after final baseline session
Session Length: Mean duration of sessions in minutes
Time Frame: First treatment session until final treatment session. Final treatment session occurs when accuracy of treatment sound is met (90% accuracy across three consecutive sessions or a maximum of 35 treatment sessions)
Start and end time of session is recorded on scoresheet, then number of minutes for each session for each participant is found and the mean across all sessions is calculated.
First treatment session until final treatment session. Final treatment session occurs when accuracy of treatment sound is met (90% accuracy across three consecutive sessions or a maximum of 35 treatment sessions)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Accuracy of production of untreated sounds measured on pretest and posttest probes
Time Frame: baseline and at posttest up to 18 weeks after final baseline session
Some children may generalize their skills learned through treatment to sounds that were not treated in the trial.
baseline and at posttest up to 18 weeks after final baseline session
