Standardized
Performance-based
Criterion-referenced
Cost: Free
How to Access: https://www.sralab.org/sites/default/files/2017-06/somct.pdf
Age: Adults (18-64), Geriatrics (65+)
Diagnoses: Alzheimer's, Progressive Dementia, Non-specific populations at risk of cognitive decline
Setting: inpatient rehab, acute rehab, home health, SNF, community programs
Short assessment examining cognitive ability and used to differentiate cognitively impaired clients while sensitive to early cognitive changes with Alzheimer's disease
Attention
Working memory
Cognition
Executive functioning
Reasoning
Problem-solving
Time: 5-10 mins
Group/Individual: Individual
Subtests: 6 items
Instructions: Clinician reads the following directions to clients: "Now I would like to ask you some questions to check your memory and concentration. Some of the questions may be easy and some of them may be hard, but please try to answer them all."
Q4- If subject begins to forget task or change instructions, repeat instructions
Acceptable responses are available on the administration & scoring guidelines
Materials: evaluation form & pencil
User Qualifications: N/A
How to Score: A sum of all incorrect answers is compiled to determine the areas of need:
Score of 1 for each error based on the number of errors allowed on each question (eg. Q1 allows 1 error max while Q6 allows 5 errors to be made)
Normal-Minimum Impairment (within normal limits): 0-8
Minimal-Moderate Impairment: 9-19
Severe Impairment: 20-28
Score Indications:
Lower scores are within normal limits with minimal impairments
Higher scores indicate severe impairments
Reliability:
Retesting 3 weeks after the initial assessment resulted in a score within 4 points of the original score
Validity:
Construct Validity-Alzheimer's: Adequate
Wechsler Memory Scale: Pearson r = - 0.562, p < 0.01
Progressive Matrices; Raven PM47: Spearman r = 0.590, p < 0.01
Criterion Validity - Non-specific Populations: Mixed
Excellent - Full Blessed Test: r=0.941
Not Significant - Barthel ADL: r=0.23
Sensitivity = 88%
Specificity = 94%
False positive = 11%
False negative = 5%
Strengths:
Quick, easy administration
Free
Dose not require additional supplies
Assesses changes in verbal memory
Sensitive to dementia symptoms/diagnoses
Weaknesses:
Scores are related to level of education attainment
Specificity in African American groups is low; cultural translation can be biased
May not validate findings with other assessments to provide a sufficient idea of cognitive impairments (this test is not enough)
No manual - administration can be swayed
