EXAM REVIEW
Assessment of Aphasia
Formal and Informal Assessment
Assessment defined as the quantitative and qualitative data-gathering process for
circumscribing an individual’s communicative function and activity limitations,
understanding their participation restriction, and devising appropriate rehabilitation
objectives.
Tools and procedures for establishing a diagnosis and prognosis, describing and
understanding all components of language functioning, gathering background
information regarding the individual with aphasia and the family, seeking input from the
person with aphasia and the family about assessment and rehabilitation goals,
supporting initial communication interactions with the individual with aphasia, and
providing family and other healthcare team members with an accurate description of
the individual’s current strengths and weaknesses are essential in the assessment
process.
No one set of tests or measures can be prescribed when assessing individuals with
aphasia. The selection of an assessment approach and procedures must be made on a
case-by-case basis, taking into consideration variables such as the client’s previous and
current level of functioning, unique current and future needs and priorities, the positive
and negative impacts of the environment, and the amount and types of assessment
resources available to the clinician.
Formal Versus Informal Assessment Procedures
Formal assessment involves administering one or more commercially available or
standardized tests, while informal assessment encompasses all the strategies that the
clinician employs to translate the symptomatology displayed by the person with a
communication disorder into clinically useful information.
Formal tests are any published quantification tool, differ in length and breadth,
purposes, and the conclusions clinicians are able to draw from the results. Formal
assessment results are quantitative and cannot guide the development of specific
treatment procedures. Informal assessment includes the essential process of gathering
specific background information through record review and interviews with the person
with aphasia and their family and caregivers.
