Acronym CKTA

Area of Assessment

Executive Functioning

Assessment Type

Performance Measure

Cost

Free

Diagnosis/Conditions

  • Pediatric + Adolescent Rehabilitation

Key Descriptions

  • 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)

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

Typically Developing Children:

(Rocke et al, 2008)

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

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.
