Population
Stroke recovery patients. The age ranges are adolecents13-17, adults ages 18-64 and elderly adults 65 and older.
Setting
Adaptive kitchen, clients home environment
Purpose & Areas Assessed
The purpose of this assessment is to assess cognitive functional performance. It also assesses Attention & Working Memory, Cognition, Executive Functioning and Life Participation
Administration
10-30 minutes to administer.
The clinician observes while the patient completes the task.
The clinician and patient then decide the details of the task to be completed.
The patient’s task is to prepare two hot drinks, one for the clinician and one for the patient.
If the client wants to prepare a beverage, allow them to determine what they want, and then ask for a drink that uses two different ingredients.

Scoring Procedure
Each item is scored on a 4-point scale based on the following criteria:
0) Intact performance
1) Slow and/or trial & error
2) Received general cues
3a) Received specific cueing
3b) Incomplete or deficient performance
4) Received physical demonstration or assistance
Scores are based on 13 indices of performance:
1) Opening the water faucet
2) Filling the kettle with about 2 cups of water
3) Turning off the faucet
4) Assembling the kettle
5) Attaching the electric cord to the kettle
6) Plugging the electric cord in an electric socket
7) Turning on the kettle
8) Assembling the ingredients
9) Putting the ingredients into the cups
10) Picking up the kettle when water boils
11) Pouring the water into the cu
12) Adding milk
13) Indication of task completion (e.g. verbal, gesture, serving)
Maximum score is 52; higher scores indicate more severe problems in performance.
Psychometrics/Standardization
Proper scoring of the data analyzed
Strengths & Weaknesses
Strength: A very client interactive activity, assesses tasks that may be their everyday functional tasks, functional relevance
Weakness: Dependent on the proper equipment and the test may not be challenging enough or may be too easy to detect subtle changes in higher-functioning individuals
