Considerations
This section of the module focuses on the different considerations that should be taken into account when deciding on an AAC system.
It is broken into four categories:
Learner Characteristics
The qualities the individual (the learner) has that might affect the way they are able to interact with AAC.
In order for AAC to be effective, the person using it needs to be able to engage with it without there being a clash between the function and running of the system and the individual’s needs.
Below is a list of some of the personal characteristics of the individual that might be taken into account when thinking about a form of AAC.
Goals
Does the form of AAC align with current and future goals for the individual?
Is the AAC adaptable to when these goals shift over time?
Attention Span
Can they hold attention long enough to use the AAC system?
Does the individual have the energy to use or operate the AAC system consistently?
Desire to communicate
Does the individual desire to communicate enough that they will persist in using this AAC system even if they are having difficulties?
Developmental stage
Is it age/developmental stage appropriate?
It is worth noting that many young children begin using easier forms of AAC, and then
progress to more intensive forms as they grow older.
Learning Ability
Is it a form that will work with the individual’s ability to learn new techniques and skills?
Literacy
Does the form of AAC align with their ability to read and write?
Mobility and Motor Skills
Are they physically able to engage with or operate the form of AAC? It is important to ensure that they are consistently able to do this most of the time.
Speech Skills and Intelligibility
Do they currently have any ability to use speech to communicate?
If they do use speech, are other people usually able to understand them?
Is the AAC form intended to replace or supplement their speech skills?
Communication/Understanding
Level of:
Receptive language: how much they understand words that have been spoken to them.
Expressive language: how much they can form their own words, sentences or phrases
and express them to other people.
For many people, one of these is easier than the other. This will influence the AAC system
chosen as different systems target different language skills, with some (such as SGDs)
targeting both.
Predicted future needs and abilities
Some individual’s use different forms of AAC throughout their life. Gaining an understanding of a person’s predicted needs and abilities early can mean that they can start learning foundational skills for current and future AAC forms early. This can help make transitions between AAC easier.
Preferences
Does the individual have clear preferences for one system over another?
Device Characteristics
The elements of the device or resource that can be considered when choosing an AAC system.
Battery Life
Does the battery last long enough that the individual is able to reliably and consistently use it?
Durability and Reliability
How strong are the systems?
Is the device known to reliably work? Or does it frequently break or stop?
Cost
Consider: upfront cost, maintenance, running and replacement costs.
Layout/Display
Is it easy to understand, operate and interact with? Is it able to be customised to individual
needs?
Portability
Can it be transported when necessary? Is the individual able to carry/move it or do they require assistance?
Vocabulary
Is the vocabulary already predetermined by the device's software? Does the device allow
for additions/removals or other control of the vocabulary by the user?
Supplier Support
Is the supplier reliable when it comes to maintenance and/or repairs?
Ease of Use
How many actions are required to complete an action? Can you expect the individual to do
this regularly?
Vocal Quality
If the AAC has a voice generation component, is the voice generation good quality?
The truth is, just giving AAC to an individual is not enough to ensure they can use it well.
To get the best outcomes, the individual needs to be taught how to use it. This means that it is vital that AAC is used in a consistent way across different areas of a person's life. This helps the person to know what is expected of them and how to gain access to what they want and need. It also helps to avoid the person getting confused, stressed, anxious or disappointed.
This next section will discuss two different areas of an individual's life where AAC can/should be implemented to get the best results.
Family
Family and whānau are an incredibly valuable resource to the individual when learning how to use the AAC. These people can provide information, reinforcement and reminders to the AAC user about when, how or why to use the AAC. An AAC system is going to be most effective when it fits into the family/whānau's daily life and creates opportunity, rather than being a stressor or chore to use. Therefore, some areas of daily life should be considered when selecting the AAC, including;
Attitudes
Whānau should be prepared to engage with the AAC.
Caregivers particularly will likely need to model using the AAC and encourage the individual to use it themselves.
Family Background
Bilingual or multilingual whānau’s - What language will the AAC use?
Does it fit within the cultural background and context? (eg. religious views/backgrounds, community values, ethics and morals).
Lifestyle
Is it compatible with regular occurring family activities?
Does the family have the time to try to support the use of the AAC?
Does the family have the resources to support the use of the AAC?
Education and Community
Education institutions (like schools or support organisations) and other places where the individual spends time are another very valuable resource when it comes to supporting them to effectively use the AAC. Many individuals with CCN also attend community education or recreational institutions where being able to communicate and connect is useful to their experience.
School/Educational Institution
Do they have any experience using AAC?
Do the staff have the knowledge and skill to work with the AAC?
If no, can they undergo training to learn it?
Is it reasonable to expect school staff to have the time and resources to work with the system consistently?
Is this space equipped and prepared to handle and implement the AAC in the same way?
The school/education space should work collaboratively with the whānau and professionals to make sure there is continuity in teaching.
Community
Are the community willing and able to learn how to use the AAC?
Does the AAC form sit in the cultural/community in a comfortable way?
Will the AAC form positively influence the individual’s ability to interact with the community in a positive way?
Ongoing collaboration and partnership between family/whānau and school/education institutions strengthens the support networks for the individual AAC user and those around them. By collaborating, the different areas of the individuals life have the same understanding of the purpose and goals of AAC use for this individual. This also creates an important support network between family/whānau and educators.
