Children's Kitchen Task Assessment

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)

Typically Developing Children:

(Rocke et al, 2008)

• Excellent interrater reliability (ICC = 0.98)

Typically Developing Children:

(Rocke et al, 2008)

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

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)

Typically Developing Children:

(Rocke et al, 2008)

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

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.
