Contextual Memory Test

Contextual Memory Test

Last Updated

Purpose

The Contextual Memory test (CMT) assesses immediate and delayed recall of 20 objects related to a scene in children and adults with memory impairments. In addition, questions before and immediately after recall objectively assess awareness of memory abilities and strategy use.

It can also be used as a screening tool to identify if a patient has a memory impairment present or if further tests need to be performed.

Key Descriptions

  • The CMT was designed to objectively measure awareness and strategy use. Testing procedures are flexible to assess various areas of recall and recognition.
  • The original paper version of the CMT was developed and published for use with adults with memory disorders in 1993. The CMT-2 is an updated, computerized version released in 2019. The CMT-2 is similar to the original CMT, but it uses colored photos and includes some item updates; Additionally, 2 scenes (morning and school) have been added for use with children.
  • Part I and II each measure 3 domains: immediate recall, delayed recall, and self-recognition
  • Part I: A picture card containing 20 related, everyday objects is presented for 90 seconds. After the 90 seconds, the screen remains hidden from the client. The therapist performing the test should say: “Tell me everything that you just saw”. The therapist will then select from a list on their computer the correct responses their client gives.
  • Part II: In this portion, the client is given a cue by being told the theme of the pictures given before viewing the pictures. Time will go for 15 minutes.
  • The scores for immediate recall, delayed recall and recognition range between 0–18 for each part of the CMT. Higher scores indicate better memory performance.
  • Scores for entire test can be summed for an overall score: Within Normal Limits = 166+; Suspect = 146 - 165; Mild = 132 - 145; Moderate = 107 -131; and Severe = 1-106 (Toglia, 1993).

Number of Items

  • 2 test cards
  • 14 cut-apart sheets (80 picture cards)
  • 25 score sheets

Time to Administer

20-60 minutes

Part I takes 10-20 minutes, then there is a 15-20 minute delay before Part II if additional testing is needed.

Required Training

Reading an Article/Manual

Required Training Description

The CMT-2 was designed to be used by licensed occupational therapists, or other licensed health professionals such as speech language pathologists and psychologists. The manual is lengthy and should be understood thoroughly prior to testing.

Examiner should be aware of administration protocol and be able to correctly score and interpret the test. Examiner should also know how to perform a dynamic assessment, including providing cues to the patient and identifying strategies to help the client optimize their performance.

Considerations

 

  • The CMT was designed to objectively measure awareness and strategy use. Testing procedures are flexible to assess both recall and recognition. Administering the CMT is simple, but the scoring and interpretation is complex. Users are encouraged to consult the original CMT manual. Assessment results are associated with treatment plans and suggested areas for additional testing
  • The CMT is not a diagnostic test. This test must be used along with other tests for diagnosis of memory impairments. Information obtained on awareness, strategy use and recall are interpreted together and are used, along with other data and tests, for the purposes of choosing and planning rehabilitation interventions.
  • The CMT-2 is appropriate for adults with traumatic brain injury (TBI), stroke, brain tumor, multiple sclerosis, Parkinson’s Disease, mild cognitive impairment (MCI), mild-mod dementia, depression, bipolar disease, schizophrenia, substance abuse disorders and other neurological or mental health conditions that can affect memory. Similarly, the CMT-2 can be used for children with neurological, developmental or mental health conditions such as intellectual developmental disability (IDD), autism, fetal alcohol syndrome, childhood brain tumor, childhood depression.
  • Not an appropriate instrument for patients with moderate or severe aphasia or visual perceptual (neglect or object recognition) deficits.
  • The CMT-2 may not be sensitive to patients with subtle memory deficits.
  • The test utilizes familiar objects as the items tested for memory. However, language and cultural barriers may affect the efficacy of the CMT if the patient is not able to recognize the items utilized in the CMT. However, It was found that the CMT can be properly used in Israeli participants, indicating that the CMT way be appropriate for use in different populations across regions. (Josman, 2000)

Standard Error of Measurement (SEM)

Mild Cognitive Impairment: (Liao, 2020; n = 83; Age Range= 57.5-80; Taiwanese Mandarin-speaking sample)

  • SEM for healthy individuals (n=44): Ranged from 0.34 - 2.75.

Minimal Detectable Change (MDC)

Mild Cognitive Impairment: (Liao et al, 2020)

  • Individuals with MCI (n=39): 
    • Acceptable random measurement error for five domains (self-awareness, self-perception/evaluation of performance, immediate/delayed/total recall): MDC% all below 30%
    • Large measurement error for the TSS domain (Part II): MDC% = 35.14%
  • Individuals with no cognitive impairment (n=44): 
    • Acceptable random measurement error for five domains (self-awareness, self-perception/evaluation of performance, immediate/delayed/total recall): MDC% all below 30%
    • Large measurement errors for the self-efficacy domain (prediction discrepancy) and TSS domain (Part II): MCD% = 32.22% and 35.24%, respectively
