Scoring Procedure (how is assessment scored and what does score indicate)
scores are based on 13 indices of performance:
opening the water faucet
filling the kettle with about 2 cups of water
turning off the faucet
assembling the kettle
attaching the electric cord to the kettle
plugging the electric cord in an electric socket
turning on the kettle
assembling the ingredients
putting the ingredients into the cups
picking up the kettle when water boils
pouring the water into the cup
adding milk
indication of task completion (e. g. verbal, gesture, serving)
each of the above items is scored on a 4-point scale:
0- intact performance
1- slow and or trial & error
2- received general cues
3- a) received specific cueing b) incomplete pr deficient performance
4- received demonstration or assistance
maximum score is 52; higher scores indicate more severe problems in performance
Psychometrics/Standardization (norms, reliability/validity studies)
inter-rater reliability 0.851 and 0.916
construct validity -0.566 and -0.659
Strengths & Weaknesses of Assessment
strengths
short
easy to administer
easy to score
free
uses common items
can do in clinic or in home
weaknesses
no normative data to compare scores
does not specify what score means when you find it
has been mostly used for people with CVA, just now beginning to be used for other cognitive deficits
we don't know how good it is for other diagnoses
