  • By combining vocabulary selection methods (i.e., reviewing source lists to identify core words, using a categorical framework, using open-ended questions, and employing a blank sheet approach), the questionnaire presents a multifaceted approach to vocabulary selection.

    SPRING 2010
    Evidence Based Practice
  • Client Information
    KH
    3:8
    Cerebral Palsy; motor speech disorder
    Little to no functional speech
    Status at the beginning of semester:
    Sign vocabulary of approx. 35 signs (mostly nouns)
    /jae/ & /nae/ to answer yes/no questions
    Guessing game
    No type of AAC device used
  • The need for more....
    Signs/speech did not reflect her ability level
    She has no cognitive deficits & receptive vocabulary is at age appropriate level
    Vocabulary increasing, MLU should be increasing
    Prevention of communication breakdowns
    The answer....Alternative Augmentative Communication (AAC) device
  • Hesitations
    No previous experience with AAC devices or board maker software
    No in depth coursework involving AAC devices
    Thus, no idea where to begin....
    Perfect opportunity for EBP
  • Clinical Question
    Population
    Intervention
    Outcome
    For children with little to no functional speech(P) , what is the best process of design for an AAC device(I) to facilitate communication outcomes during therapy (O)?
  • Vocabulary Selection
    Vocabulary selection for augmentative communication systems: A comparison of three techniques.
    Enhancing vocabulary selection for preschoolers who require augmentative and alternative communication (AAC).
  • Results
    Article #1) Vocabulary checklist was most effective in comparison with blank sheets & categorical tools, Parents provide the most vocabulary information.
    Article #2) Vocabulary Selection Questionnaire allows one to efficiently select appropriate, meaningful vocabulary by combining vocabulary selection methods . Parents provide most information.
  • Color Cues
    Article 3: The effect of color cues on typically developing preschoolers’ speed of locating a target line drawing: Implications for augmentative and alternative communication display design
  • Results
    Color characteristics of certain stimuli influence reaction time of locating target symbols
    Foreground color
    Background color (relevance)
  • Item Example
  • How was this information applied?
    Discussed AAC device with the parents (needs, benefits)
    Sent home the Vocabulary Selection Questionnaire
    Used board maker software to compile personalized boards based on VSQ
    Used specific color cues within design of each board
  • Results in Therapy
    First session served as introduction to new AAC
    Discussed the importance of modeling
    Applicable Short term goals:
    KH will use communication board to express wants/needs in 3 parts with verbal prompts and visual modeling .
    • Able to use new AAC device in 3 parts during first trial (“I am happy,” “I want pancakes”)
    • Both parents & client seem more excited and appreciative
  • Next Steps
    Electonic AAC device
    Dynavox
    Use current design as a guide for limitations/improvements
    Parent Training
