The Kitchen Task Assessment (KTA)
Transcript of The Kitchen Task Assessment (KTA)
Validity & Reliability
1. Place to the left on the counter
• 2-3 types of pudding mix (the kind that requires cooking; not instant)
• 1-1 ½ quart saucepan with heat-resistant handle
• A wooden spoon
• A rubber scraper
• A 2 cup measuring glass
• 4 small dishes (paper cups will do)
2. Have a quart of milk in the refrigerator
3. Print the instructions in large letters on a piece of paper and mount the instructions where the person can read them. Use the same instructions that are on the box, except add, "pour into cups."
4. Have hand soap and paper towels near the sink.
5 Analyses Conducted:
Kendall's tau B to determine the inter-rater reliability of the KTA;
Correlation analysis to examine the relationship among the six variables in the measure;
Factor analysis to identify common relationships among the variables;
Correlation analysis with other valid instruments to determine the construct validity of the KTA;
Analysis of variance to examine the KTA across stages of SDAT and between men and women.
The Kitchen Task Assessment (KTA) is a “functional measure that records the level of cognitive support required by a person with Senile Dementia of the Alzheimer's Type (SDAT) to complete a cooking task successfully.”
The KTA tests the cognitive ability of the impaired person to complete the task of making cooked pudding from commercial package.
Developed in 1983 in order to provide occupational therapists with a performance-based standardized assessment that can also be used to record change in performance over time.
The Kitchen Task Assessment (KTA)
The KTA evaluates:
Cognitive processes that affect task performance and records the level of cognitive support necessary for successful task completion;
Can be performed either in a clinic or in the person's home in a short period of time;
Allows the clinician to observe and translate the person's performance into strategies the caregiver may use to manage the cognitively impaired person on other activities of daily living and instrumental tasks;
Generates a score to measure changes in performance over time (either progression or improvement).

OTP I- Individual Project
Tell the person to:
• Mix a box of pudding and pour the mixture into four dishes
• That the milk is in the refrigerator
• How the stove works and what burner to use
• That the instructions are on the box and on the wall
• To begin when ready
• You will cue only after you have determined he or she cannot perform without help (wait five seconds) UNLESS safety is an issue.
• The level of support required from the tester for each component is scored:
0 (independently competent), 1 (required verbal cue),
2 (required physical assistance),
3 (totally incapable).
• The higher the score, the more impaired the performance (total scores range from 0 -18)
