Computer Assessment of Memory and Cognitive Impairment(CAMCI)-Research is a customizable battery of computerized tasks to assess cognitive performance. Computer-administered and self-paced, this investigative tool allows researchers to arrange a protocol of tasks to collect accuracy and reaction time data for comparison to normative data. There are 9 behavioral tasks included in the complete CAMCI-Research battery. Additionally, a series of self-report questions may be presented to gain information from the participant regarding factors that could affect the participant’s performance on the CAMCI-Research tasks (e.g., perceived memory loss, alcohol use, depression, anxiety, etc.).
CAMCI-Research accurately assesses cognitive performance using standard neuropsychological tests of memory, attention, and executive ability modified for computer administration. Plus – an innovative Virtual Environment task tests 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-Research application allows the researcher to design protocols by selecting and arranging tasks to run from the battery provided. The researcher may define instructions to be presented to the examiner prior to or following a test session, or choose to present screens to welcome or dismiss the subject. Customization also allows the researcher to select events to assess the suitability of the computer’s timing for data collection and the accuracy of the input calibration, or to require a security pass code to limit the accessibility to reports after a test session is completed.
Results are available immediately following each test session, including comparison of task measures to age and/or education adjusted normative data. Performance on each CAMCI-Research task is recorded in trial-level and summary task-level data files to allow further, detailed analysis.
Intended use: The CAMCI-Research product is for research, investigational, or educational use only. CAMCI-Research does not offer a medical diagnosis.

The length of time to complete depends on the tasks selected by the researcher and the pace of the subject. During normative data collection, the average time to complete the entire battery of tasks was 25 minutes, with individual tasks ranging from 2-7 minutes to complete.
CAMCI-Research is administered via tablet computer using touchscreen technology for response input, and takes about 25 minutes to complete. The tasks are administered via computer, so no task administration training is required. The subject completes the tasks at their own pace, requiring little to no oversight during a test session. The test runs on a tablet computer allowing greater portability and flexibility than desktop computers. This approach ensures standardized administration and scoring, thus avoiding inter-site and inter-examiner variability. Performance can be age and education adjusted (based on normative data) to provide a comprehensive summary score.
The CAMCI-Research tasks have used in research studies addressing cognitive assessment of primary care patients, intervention in dementia, traumatic brain injury, HIV-related cognitive decline, mobility assessment and exercise interventions, as well as in studies examining the elderly and arthritis, and neurocognitive outcomes following cardiac arrest. Thousands of participants have completed the CAMCI-Research tasks with overwhelmingly positive results. A list of studies that have used the CAMCI-Research tasks with brief summaries is below:

- The study examined detecting HIV-associated dementia at the earliest possible time by using cognitive screening. The examiners used the CAMCI-Research tasks for the testing. The study demonstrated that the CAMCI-Research tasks were sensitive to mild forms of cognitive impairment and was stable over weeks of follow-up.
