© 2017 American Speech-Language-Hearing Association. Purpose: The aim was to evaluate the effectiveness of computer-assisted input-based intervention for children with speech sound disorders (SSD). Method: The Sound Start Study was a cluster-randomized controlled trial. Seventy-nine early childhood centers were invited to participate, 45 were recruited, and 1,205 parents and educators of 4- and 5-year-old children returned questionnaires. Children whose parents and educators had concerns about speech were assessed (n =275); 132 children who were identified with phonological patternbased errors underwent additional assessment. Children with SSD and no difficulties with receptive language or hearing, typical nonverbal intelligence, and English as their primary language were eligible; 123 were randomized into two groups (intervention n = 65; control n = 58), and 3 withdrew. The intervention group involved Phoneme Factory Sound Sorter software (Wren & Roulstone, 2013) administered by educators over 9 weeks; the control group involved typical classroom practices. Participants were reassessed twice by a speech-language pathologist who was unaware of the initial assessment and intervention conditions. Results: For the primary outcome variable (percentage of consonants correct), the significant mean change from pre- to postintervention for the intervention group (mean change = +6.15,
The Speech-Associated Attitude of Children Who Do and Do Not Stutter and the Differential Effect of Age
Fifty-five Flemish children, ages 6 to 13, who stuttered and 55 who did not were the subjects of a two (group) by eight (age) factorial investigation of their response to a Dutch translation of the Communication Attitude Test (C.A.T.). The main effect results confirmed previous C.A.T. findings that, as early as age 6, children who stutter exhibit significantly more in the way of a negative speech-associated attitude than their peers do. In addition, the between-group difference in attitude diverged with age. The C.A.T. scores increased for those who stuttered and decreased for the normally fluent children. These data suggest that the attitude of the two groups of children was differentially affected by their speech-related experience history. It follows from this, and the other findings of the study, that the attitude toward speech of children who stutter warrants early clinical consideration and attention
