Title of Assessment

Children's Kitchen Task Assessment 

Acronym

CKTA

Instrument Reviewer(s)

Initially reviewed by Jill Smiley, MPH and the Rehabilitation Measures Database Team in August 2014.

Summary Date

8/1/2014 

Purpose

To assess executive function in children 8-12 through the child’s performance of making play dough.

Description

Create this kit before performing the assessment.

It is important for the tools to match the photographs. If unable to match, then take a photograph and replace the one in the kit.

Practicing with another professional is encouraged, as the way a cue is delivered can influence the child’s performance.

Normative Data

Typically Developing Children:
(Rocke et al, 2008; n = 49 typically developing African American children aged 8-12 years; mean age = 10.4 (1.12) years; sex = 69% female; 49% single parent homes) 
  • Mean total score for all participants = 11.84 (8.80)
  • Mean number of cues for test as a whole = 9.02 (5.89)

Children with Sickle Cell Disease (SCD):

(Berg et al, 2012; n = 44 African American Children aged 8-12 years, 22 with SCD and 22 Controls; sex = 26 females and 18 males; mean age of controls = 10(1.52) years; mean age of children with SCD = 10.23 (1.42) years)

Test-retest Reliability

Not Established

Interrater/Intrarater Reliability

Typically Developing Children:

(Rocke et al, 2008)

  • Excellent interrater reliability (ICC = 0.98)

Internal Consistency

Typically Developing Children:

(Rocke et al, 2008)

  • Poor internal consistency (Cronbach's alpha = 0.68)

Criterion Validity (Predictive/Concurrent)

Typically Developing Children:

(Rocke et al, 2008)

  • Adequate correlation between total CKTA and WISC-IV Digit Span (r = -0.31)
  • Adequate correlation between total CKTA and BRIEF (r = 0.34)
  • Adequate correlation between the organization subscale of CKTA and and the plan and organized subscale of BRIEF (r = 0.38)
  • Adequate correlation between the judgement and safety subscale of CKTA and and the monitor subscale of BRIEF (r = -0.35)
  • Adequate correlation between the planning and sequencing subscale of CKTA and and the D-KEFS Confirmed Correct Card Sorts(r = -0.33)
  • Adequate correlation between the planning and sequencing subscale of CKTA and and the Total Description Score (r = -0.30)

Construct Validity (Convergent/Discriminant)

Typically Developing Children:

(Rocke et al, 2008)

  • There is evidence of discriminant validity because two blind raters are able to make the same assessment

Content Validity

Not Established

Face Validity

Children with Sickle Cell Disease:

(Berg et al, 2012)

  • Even when controlled by age and for SES distribution, the CKTA results are apparent. It observes the child in action and is not dependent on verbal instruction or recall.
