Cognitive Linguistic Quick Test (CLQT)

By: Grace Castillo & Christine Truong

What Does This Assessment Test?

• The purpose of the CLQT is to quickly assess

the relative status of 5 cognitive domains:

○ Attention ○ Memory ○ Language ○ Executive Function ○ Visuospatial Skills

• An individually administered test designed to

gain information about cognitive-linguistic functioning

• Provides an overall measure of

cognitive-linguistic function

• May be used to identify an individual’s

cognitive strengths and weaknesses

What Does This Assessment Test?

• It yields information that can identify

domain-specific strengths that may be used to compensate for compromised areas of cognition

• This information is essential both to

identifying areas for direct treatment and the everyday management of impaired skills

• It can also indicate the need for more in-depth

testing & assist in determining a differential diagnosis

○ The CLQT was not developed as a comprehensive tool to determine differential diagnosis

• The results should lead to additional
• bservation and/or the administration of

more in-depth formal & informal measures in the specific areas in which the examinee had difficulty

• The CLQT is a quick “snapshot” of the

individual’s skills in order to develop a plan of action, advise family members, and direct care staff

What Target Population is it Appropriate For?

• Adults with known or suspected acquired

neurological dysfunction

○ Stroke ○ TBI ○ Dementia

• Appropriate for English or Spanish speaking

adults

• Adults between the ages of 18-89

What Are the Different Sections of the Test?

5 Cognitive Domains:

• Attention
• Memory
• Executive Function
• Language
• Visuospatial Skills

10 CLQT Tasks:

• Personal Facts*
• Symbol Cancellation*
• Confrontation Naming*
• Clock Drawing
• Story Retelling
• Symbol Trails
• Generative Naming
• Design Memory
• Mazes
• Design Generation

10 CLQT Tasks

1. Personal Facts: designed to help assess episodic memory, orientation to place & year, and the ability to communicate these facts through language. 2. Symbol Cancellation: Designed to help assess visual attention, scanning, discrimination, inhibition, and response shifting within quadrants of space. 3. Confrontation Naming: Designed to help document anomia. 4. Clock Drawing: Designed to help obtain a quick gauge of spontaneous recovery, progress during rehabilitation, or declines caused by progressive disease. 5. Story Retelling: Designed to help assess the examinee’s working memory for facts embedded in a story narrative and to assess auditory processing and verbal production skills. 6. Symbol Trails: Designed to help assess the executive function of working memory and of planning and mental flexibility without placing demands on the language system.

10 CLQT Tasks Cont.

7. Generative Naming: Designed to help evaluate the examinee’s ability to conduct a systematic mental search for words according to specific semantic & phonological rules, as well as to employ their working memory skills to remember task rules and words already named. 8. Design Memory: Designed to help assess the examinee’s immediate/working visual memory with minimal language demands. 9. Mazes: Designed to help assess executive functions while placing minimal demands on the language system. 10. Design Generation: Designed to help assess the examinee’s executive skills of productivity and creativity, the ability to vary responses rapidly, to self-monitor, to remember and follow rules, and to develop and use effective strategies.

How Do You Give the Assessment?

Test Supplies Needed:

• CLQT Examiner’s Manual
• CLQT Stimulus Manual
• CLQT Record Form
• CLQT Response Booklet
• CLQT Scoring Transparencies for Symbol

Cancellation and Symbol Trail tasks

• Pen for the examinee’s use
• Stopwatch or a watch that can measure

seconds Administration Tips:

• The test can be administered in 15-30

minutes

• It can be administered bedside or while

seated at a table, though 5 out of 10 tasks require the examinee to manipulate a pen with the dominant or non-dominant hand

• 4 of the tasks require only verbal responses
• Administer all tasks in the order they appear

in the Record Form

• Follow specific directions in the Record Form
• Read the dark blue instructions in the Record

Form to the examinee

Testing Environment

• Schedule a testing time when the examinee is

alert and rested

• Make sure examinee has devices he/she

typically uses (hearing aids, glasses, dentures)

• Choose a quiet, well-lit room
• Have a clear table or flat surface available
• Sit across from the examinee or on their

unaffected side if he/she has hemiparesis, hemianopia or visual field neglect

• Position the examinee where he/she cannot

see a clock or calendar

• Keep Record Form away from examinee’s

view

Cognitive Domains Evaluated

How Severity Ratings Are Determined

Scoring Each Task

• Personal Facts

○ 1 point= correct response ○ 0 points= incorrect response ○ Only verbal responses receive credit ○ Description: ■ 5-second delay ■ Self-corrected ■ Probe needed ■ Perseveration ■ Unintelligible ■ No response

• Symbol Cancellation

○ Total correct-Total incorrect= symbol cancellation score

• Confrontation Naming

○ 1 point= correct response ○ Half point= at least half of phonemes or syllables correctly ○ 0 points= less than half of phonemes or syllables correct

• Clock Drawing

○ Place check marks under corresponding responses ○ Numbered scores for correct/incorrect

Scoring Each Task

• Story Retelling

○ Checkmark when the examinee recalls either the element in boldface print or an acceptable variation

• Symbol Trails

○ Scoring transparency page is used ○ 1 point=each line that corresponds to the transparency

• Generative Naming

○ Record the examinee’s responses verbatim in each of the 15-second increments in the spaces provided on the record sheet

• Design Memory

○ 0= incorrect ○ NR= no response ○ SC= self corrected

Scoring Each Task

• Mazes

○ 4 points= correctly completing the maze ○ 3 points= if the examinee completes Maze 2 until the wall directly above the money ○ 0 points= look at scoring guidelines ○ Subtract 1 point each time a line goes half an inch out of the alley

• Design Generation

○ Count the total number of designs drawn by the examinee ○ The scoring guidelines will help determine the score

How Do You Score the Test?

Overall Test

• Criterion-referenced test with severity ratings

for 2 age categories

• Severity ratings: mild, moderate, severe and

WNL are established for each of the 5 cognitive domains Recording Summary Scores

• Transfer the scores for each task to the

Cognitive Domain Score

• Determine Criterion Cut Scores of Individual

Tasks

• Transfer the Cognitive Domain Scores to the

Severity Ratings Table to determine severity

• Determine the Composite Severity Rating
• Complete the Severity Ratings Summary
