High-intensity vs Low-intensity Speech Intervention in Children With Phonological Speech Sound Disorders
The Short- and Long-Term Effects and Cost-Effectiveness of High-Intensity Versus Low-Intensity Speech Intervention in Children With Phonological Speech Sound Disorders.
Achieving speech that is understandable and acceptable to others is the key outcome in the treatment of phonological speech sound disorders. Therefore, speech therapy provided by a speech-language pathologist is essential. Traditionally, this intervention has been delivered twice per week for 30 minutes, often over the course of several months or even years, by first-line speech-language pathologists. Unfortunately, this low-intensity approach is largely based on historical practice rather than scientific evidence.
The current study aims to provide stronger evidence regarding the optimal intensity of intervention. Specifically, this project will compare the effects of high-intensity and low-intensity speech intervention in children with phonological speech sound disorders in terms of speech outcomes, quality of life, and cost-utility. The interventions will be provided by first-line speech-language pathologists within a large-scale randomized controlled trial. The ultimate goal is to implement this program in clinical practice and raise awareness among stakeholders about its benefits for children with phonological speech sound disorders

Eksperymentalny: High-intensity Speech Intervention
To investigate the (cost-)effectiveness of speech therapy for children with phonological speech sound disorders, a community based SLP will provide a high-intensity speech intervention.
|
Children will receive phonological speech therapy supplemented by phonetic principles.
A next level will be introduced when the child is able to correctly produce the sound in 80% of the time with minimal cues from the therapist.
Multiple errors will be targeted simultaneously by focusing on a process.
Child-friendly games will be played to illustrate the contrast between concepts.
Exercises will be embedded in meaningful language contexts such as minimal pairs.
Therapy will be provided 5 times 30' per week for 2 times 2 weeks.

Consonant proficiency (percentage correctly produced consonants)

Incremental cost-utility ratio
Ramy czasowe: Assessment immediately pre-intervention, after 5 hours of therapy, after a 6-week rest period, immediately post-intervention, at 12 weeks post-intervention
|
The cost-utility of the high intensity speech intervention compared to the low intensity speech intervention will be examined by calculating the ratio of the incremental costs to the incremental health effects (QALYs) called the incremental cost-utility ratio (ICUR), calculated as Cost intervention - Cost control / Effect intervention - Effect control.
The EQ-5D-Youth version will be used for children aged 8-12 years and the EQ-5D proxy version for children aged 4-7 years to collect information on HRQoL ("utilities").
Cost information will be obtained using a self-reported questionnaire on health care use.

The cost-effectiveness of the high intensity speech intervention compared to the low intensity speech intervention will be examined by calculating the ratio of the incremental costs to the incremental health effects (percentage correctly produced consonants) called the incremental cost-effectiveness ratio (ICER), calculated as Cost intervention - Cost control / Effect intervention - Effect control.
The effectiveness will be estimated using the primary outcome (percentage correctly produced consonants) obtained from the randomized controlled trial.
Cost information will be obtained using a self-reported questionnaire on health care use.

Intelligibility in Context Scale (ICS)
Ramy czasowe: Assessment 2 weeks pre-intervention, immediately pre-intervention, after 5 hours of therapy, after a 6-week rest period, immediately post-intervention, at 2 weeks post-intervention, at 12 weeks post-intervention
|
To assess possible transfer of learned speech skills to contexts outside the therapy setting, the Intelligibility in Context Scale (ICS) will be administered.
The ICS rates the degree to which children's speech is understood by different partners (caregivers, immediate and extended family, friends, acquaintances, teachers, and strangers) on a 5-point scale (1 - never intelligible to 5 - always intelligible) with a minimum score of 7 and a maximum score of 35.
The higher the score, the better the result.

Communication attitudes of children aged 4 and 5 years (KiddyCAT)
Ramy czasowe: Assessment immediately pre-intervention, after 5 hours of therapy, after a 6-week rest period, immediately post-intervention, at 12 weeks post-intervention
|
To evaluate the change in communication attitudes of children aged 4 and 5 years during the intervention, the KiddyCAT will be administered before, during and after the intervention.
This questionnaire evaluates the extent to which the child has a negative attitude toward speaking.
The higher the score, the more negative the attitude toward speaking.
the scores range from 0 (no negative communication attitudes) to 14 (negative communication attitudes only).

Phonological Awareness subtest from the CELF-Preschool-II-NL
Ramy czasowe: Assessment immediately pre-intervention, after 5 hours of therapy, after a 6-week rest period, immediately post-intervention, at 12 weeks post-intervention

The instrument targets two hierarchical levels of phonological awareness and consists of 6 subtests of 4 test items.
Minimum raw score is 0 and maximum possible score is 24, with higher scores reflecting better phonological awareness skills.

Dutch Phonological Awareness Test (Proef Fonologisch Bewustzijn)
Ramy czasowe: Assessment immediately pre-intervention, after 5 hours of therapy, after a 6-week rest period, immediately post-intervention, at 12 weeks post-intervention
|
The instrument targets three hierarchical levels of phonological awareness and consists of four subtests of 10 test items.
Children are asked to rhyme, to segment words in syllables, to combine phonemes into words and the repeat non-words.
Minimum raw score is 0 and maximum possible score is 40, with higher scores reflecting better phonological awareness skills.
