Key Descriptions

  • The EFPT is a top-down performance assessment designed to examine cognitive integration and functioning.
  • The EFPT serves three purposes:
    1) To determine which executive functions are impacting function
    2) To determine an individual’s capacity for independent functioning
    3) To determine the amount of assistance necessary for task completion
  • The assessments requires participants to complete the following tasks (in order):
    1) Hand Washing - only use this task if the person has severe cognitive impairment and you want to see if they can follow directions. If they cannot, do not proceed.
    2) Oatmeal Preparation
    3) Telephone
    4) Taking Medication
    5) Paying Bills

Considerations

  • The EFPT should only be administered once per patient secondary to a learning effect that may confound the results of a second assessment.
  • A Korean version of the EFPT, the EFPT-K,  was created in order to be more culturally appropriate (Kim, H., Lee, Y., Jo, E., Lee, E., 2017).
  • The EFPT has also been translated into Swedish. (Cederfeldt, M., Carlsson, G., Dahlin–Ivanoff, S., & Gosman–Hedstrom, G., 2015).
