Study: PROMIS Applied Cognition-Abilities scales demonstrates robust statistical properties in first Canadian analysis

This study and subsequent article, completed by Boaz Y. Saffer, Dr. Shawnda Lanting, Dr. Michael Koehle and Dr. Grant Iverson, will appear in the Journal of Psychiatry Research.

Context

Having brief, standardized, reliable, and valid questionnaires that assess cognitive impairment is important for both psychiatric and general medical practice. To date, few questionnaires have successfully met these requirements. The PROMIS(R) Applied Cognition-Abilities scales were developed, evaluated, and distributed by the National Institutes of Health (NIH) in the United States to address these limitations. Despite demonstrating encouraging statistical properties, however, the PROMIS(R) Applied-Cognition-Abilities scales have yet to be examined in Canada and with a heterogeneous healthcare population.

Objective and Method

The PROMIS(R) Applied Cognition-Abilities scales were included by the Brain Health Department at Copeman Healthcare as part of an annual wellness screen. Clients consenting to participate in this study completed the scales along with other measures assessing mental wellbeing. The data for these scales were collected and analyzed.

Results

Our analyses found that the PROMIS(R) Applied Cognition-Abilities scales demonstrate robust statistical properties (including excellent internal consistency reliability) adding to the findings that these scales represent promising instruments to include in assessing for cognitive impairment.
