Abstract<\/strong><\/p>\n

Fidelity of Implementation (FOI) measures how well an intervention is delivered as intended, which is crucial for evaluating its effectiveness. This thesis examines how FOI influences intervention outcomes, focusing on stuttering interventions for children in home settings. It aims to understand FOI reporting in previous studies, evaluate a pilot home-based stuttering intervention (STOC) with detailed FOI measurements, achieve high FOI in a controlled study, and determine the relationship between FOI and outcomes in school-aged children who stutter.<\/p>\n

The research involved a systematic literature review of 36 papers (1981-2021) analyzing four FOI components: dosage, adherence, quality, and responsiveness. A single case experimental design was used with seven children (9-13 years) for the STOC intervention, monitored over 18-30 months. The intervention sessions were evaluated based on the four FOI components.<\/p>\n

Results showed inconsistent FOI reporting, with dosage most frequently reported and responsiveness least reported. The STOC pilot study demonstrated reduced stuttering and improved fluency and quality of life for participants. Higher dosage and adherence were linked to better outcomes, while quality and responsiveness increased speech output but didn’t reduce stuttering.<\/p>\n

In conclusion, poor FOI reporting in stuttering research hinders accurate interpretation of findings. The STOC study showed that better adherence leads to improved outcomes. Comprehensive FOI examination can provide insights into intervention variability, highlighting the need for thorough FOI measurement and reporting in future studies.<\/p>\n
