Experimental: CAMCI Validation
Completion of computerized tasks (Computer Assessment of Memory and Cognitive Impairment) and traditional neuropsychological tests administered via paper-pencil method by a trained administrator
|
CAMCI is a computerized screening tool for the assessment of cognitive status.
CAMCI accurately assesses cognitive performance using standard neuropsychological tests of memory, attention, and executive ability modified for computer administration, and an innovative Virtual Environment task, testing domains such as incidental memory, not easily assessed using paper-pencil tests.
Computer-administered tasks ensure standard administration and scoring, avoiding inter-site and inter-examiner variability.
The CAMCI battery consists of tasks testing multiple aspects of cognitive function, and a series of self-report questions administered via tablet computer.
Using touchscreen technology for response input, CAMCI takes approximately 15-20 minutes to complete.
Other Names:
The Montreal Cognitive Assessment (MoCA) is a rapid screening tool used to detect mild cognitive impairment (MCI), assessing cognitive domains (visuospatial skills, executive function, memory, attention, language, and orientation). Individual test scores are summed into a total score from 0 (worst) to 30 (best). Individuals may achieve any score within that range. Individual test scores are not reported. Scores: 26-30 considered Normal; 19-25 may suggest Mild Cognitive Impairment (MCI); 10-18 can suggest moderate impairment; < 10 may indicate severe impairment
Other Names:
Cognitive status assessed by traditional neuropsychological tests measuring visuospatial skills, executive function, memory, attention, language, orientation. Results compared to age-adjusted norms, reviewed by expert neuropsychologists for consensus classification, per Univ of Pittsburgh Alzheimers Disease Research Ctr and Ntl Alzheimers Coordinating Ctr, and Alzheimer's Assoc criteria. Final classification adjusted per clinical judgment. Impaired: ≥3 scores ≥2SD below norms Indeterminate: ≤2 scores >1SD below norms Normal: Neither criteria met. Total and domain scores not reported.

Primary Outcome Measures

Measure Description |
Time Frame |
|---|---|---|
|
Agreement Analysis (Agreement to Reference Standard) - Test Group
Time Frame: baseline
|
Comparison (positive and negative percent agreement, confidence interval estimates, and quadratic weighted kappa) between CAMCI and clinical adjudication classifications for the Test group.
Power calculations for agreement were assessed for Cohen Kappa's assuming at least 75% Normals with 80% power and .05
significance level, finding that we were sufficiently powered with at least 120 individuals in the test set, for a Kappa of at least 0.3.

|
|
Agreement Analysis (Agreement to Non-Reference Standard) - Test Group
Time Frame: baseline
|
Linear regression agreement analysis (linear regression equation and confidence intervals, and Pearson correlation) between CAMCI and Montreal Cognitive Assessment (MoCA) for the Test group. Comparison (positive and negative percent agreement, confidence interval estimates, and quadratic weighted kappa) between CAMCI and Montreal Cognitive Assessment (MoCA) for the Test group. CAMCI Scores ranged from 0-50, higher scores mean better outcome. MoCA scores ranged from 0-30, higher scores mean better outcome. Power calculations for agreement were assessed for Cohen Kappa's assuming at least 75% Normals with 80% power and .05 significance level, finding that we were sufficiently powered with at least 120 individuals in the test set, for a Kappa of at least 0.3. |

Criterion validity correlation analysis
Time Frame: baseline
|
Analysis of correlations between CAMCI accuracy measures (i.e., accuracy of responses within individual tasks) and individual paper and pencil neuropsychological tests (i.e., scores achieved on individual tests) to assess both convergent (high correlations with related measures) and divergent (lower correlations with measures that should not be related) validity.

Change Metric (Measure of Significant Change)
Time Frame: baseline, 6 months, 12 months, 24 months post baseline
|
To derive a measure of reliable change that addressed unbalanced repeated measures and unequal timing of repeat measures, we built a two-stage hierarchical model for longitudinal data using Bayesian methods. Additionally, the standard deviation (SD) was allowed to change over time, which allowed for computation of an intraclass correlation coefficient (ICC), a measure of reliability. With an SD and ICC that can change over time, reliable change was computed for follow-up months from 3 to 24, in groups of 3. Reliable change was then adjusted for practice effects according to Duff, K. (2012). Computer Assessment of Memory and Cognitive Impairment (CAMCI) scores were calculated as the weighted sum of individual task scores converted to a total score from 0-worst to 50-best. As the intended use of CAMCI is to provide a single score of overall cognitive status, individual task scores were not reported. |

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
IPD Plan Description
Quality-controlled raw data as well as processed data used in publications will be made available. Shared data will include computerized task scores, neuropsychological test scores, and full analytical codes used to process and analyze the data. Workflows will be described and documented to allow replication of results from the raw data.
Data and corresponding documentation will be made available through Open Science Framework, in addition to any potential requirements on software sharing by journals.
The PI or Co-Investigators will disseminate results from this research through presentations at public lectures, scientific institutions and meetings, and/or publication in major journals. The PI and Co-Investigators will adhere to the NIH Grants Policy on Sharing of Unique Research Resources including the Sharing of Biomedical Research Resources: Guidelines for Recipients of NIH Grants and Contracts on Obtaining and Disseminating Biomedical Research Resources.
IPD Sharing Time Frame
Data will be deposited into the repository indicated above as soon as possible, but no later than 4 years after the end of the award project period.
The Small Business Act provides authority for NIH to protect from disclosure and nongovernmental use all Small Business Innovative Research (SBIR) data developed from work performed under an SBIR funding agreement for a period of 4 years after the closeout of either a phase I or phase II grant unless NIH obtains permission from the awardee to disclose these data. The data rights protection period lapses only upon expiration of the protection period applicable to the SBIR award, or by agreement between the small business concern and NIH.
