Dynamic Assessment of Phonological Disorders
Speech Sound Disorder
About this trial
This is an interventional treatment trial for Speech Sound Disorder focused on measuring phonology, delay, disorder, speech
Eligibility Criteria
Inclusion Criteria: monolingual English speakers; scores in the mild to profound range for phonological disorder based on the Hodson Assessment of Phonological Patterns (Hodson, 2004); scores above 9th percentile on receptive language and cognitive abilities based on measures from the Preschool Language Scale-4 (PLS-4) (Zimmerman, Steiner, & Pond, 2002) and the Peabody Picture Vocabulary Test (PPVT) (Dunn & Dunn, 1997); perform adequately on a structural-functional examination adapted from the Oral and Speech Motor Control Protocol (Robbins & Klee, 1987) and Motor Speech Examination (Strand & McCauley, 1999); exhibit voice and fluency skills within normal limits, pass a hearing screening adequate for understanding speech. Exclusion Criteria: will not exhibit the prime characteristics of developmental apraxia of speech and/or dysarthria

Easier Targets
Harder Targets
All participants will participate in a modified Cycles approach where speech targets are worked on for a short period of time and switched within a cycle. During the Easier Targets arm, children will work on target sounds that are "easier" based on their pre-treatment scores of 8, 9, 10, or 11 on the Glaspey Dynamic Assessment of Phonology. Children will complete 8 sessions in this arm that are each 50-minutes long and occur two times per week with each target addressed for 2 sessions.
