Description of intervention(s) / exposure
This project will collect outcome data for an individual treatment with supported self-help treatment. Treatment will involve student speech pathologists (supervised by the Clinical Educator who is also a member of the research team) facilitating the treatment. The treatment protocol involves teaching fluency techniques, addressing thoughts and feelings associated with stuttering, and individual goal setting. The individual treatment will be provided to 12 individuals using The Camperdown Program to address childhood stuttering and supported self-help using 'The Happiness Trap- Pocketbook Edition'. During the sessions with the student speech pathologists, participants will be taught prolonged speech techniques to control stuttering, using the Camperdown Program method. Participants will be assigned a chapter per night to read and complete the exercises in The Happiness Trap Pocketbook. The student speech pathologists will review The Happiness Trap Pocketbook exercises completed at home during the first third of the session, and spend the remainder of the session teaching and practising prolonged speech, and in later sessions, problem-solving transfer of skills beyond the clinic. In addition to completing the self-help exercises in The Happiness Trap Pocketbook, participants will also be requested to practise their prolonged speech technique between clinic visits.

Outcome measures will be obtained on 4 separate occasions: pre-treatment, immediately post-treatment, one month post-treatment and at a 9 month follow up session.

Treatment occurs twice per week for a total of 3 weeks duration. Treatment will be provided face-to-face at one of three locations: the Flinders University Fluency Clinics (Women's and Children's Hospital or Flinders Medical Centre) or a private practice 'Swift Speech and Stuttering'. The treatment program will be based on standard care but will be personalised dependent on the child and family/caregiver's goals.

Participants will complete a total of 10 study visits - one pre-treatment study visit, 6 treatment sessions (twice weekly for 3 weeks) and a further 3 post-treatment study visits immediately post-treatment, one month post-treatment and 9 months post-treatment.

Statistical methods / analysis
Critical realistic evaluation methodology is the analysis approach used in this study. It provides a holistic approach towards the analysis of the proposed intervention by analysing the various contexts and mechanisms that give rise to positive and negative outcomes and expresses these in the form of Context-Mechanism-Outcome (CMO) configurations or hypotheses. The formulation of CMO hypotheses occurs via semi-structured interviews, supported with quantitative data from various speech, communication and anxiety measures. To form the CMO configurations the data from each participant is entered into a Participation Matrix. The Participation Matrix is a combination of demographic data, quantitative data results, as well as the qualitative data analysis (thematic analysis coding). These contexts, mechanisms and outcomes are combined for each participant and across participants to formulate CMO hypotheses.
Twelve participants were chosen as the target participant number as there is research supporting the achievement of saturation or near-saturation of qualitative data after 12 participants.

Summary
Brief summary
This research aims to collect outcome data from an individual treatment with supported self-help for school-aged children who stutter. The results will be analysed to identify what factors lead to successful and unsuccessful outcomes in school-aged children who stutter. These factors will be compared to existing data to create theories that can explain what factors create optimal outcomes in school-aged children who stutter.

Stuttering can impact upon a child’s academic achievement and affect psychological, emotional and social well-being. Research into treatments for school-aged stuttering is limited. Treatment currently involves teaching fluency-enhancing skills to control stuttered speech and changing negative thoughts, feelings and avoidance behaviours associated with speaking. However, relapse after treatment is estimated to occur in 30% to 60% of clients, and increases with client age. Therefore, it is important to understand what factors are associated with successful and unsuccessful treatment outcomes to guide future speech pathology practice in the area of childhood stuttering treatments.
