Abstract
As new measures of memory become available, clinicians may be cautious to adopt them without evidence supporting their validity. The present study assesses the convergent and divergent validity of the Child and Adolescent Memory Profile (ChAMP), with the California Verbal Learning Test Children’s (CVLT-C) and the Rey Complex Figure Test (RCFT) in children with epilepsy.
Twenty four clinically referred children (16 female, 8 male, - age = 12.37 years, SD = 2.68) completed the ChAMP, CVLT-C, and RCFT. Pearson correlations assessed the ChAMP’s convergent and divergent validity with the CVLT-C and the RCFT. Base rate of impairment was calculated for scores ≤2nd percentile.
The ChAMP verbal tasks demonstrated strong relations with CVLT-C (lists; r = 0.678 p = < .001, instructions; r = 0.724 p = < .001 with CVLT-C learning trials and ChAMP lists free recall with CVLT-C long delay r = 0.580 p = .003). The ChAMP visual tasks correlated strongly with the RCFT delay (objects; r = 0.570 p = .004, places; r = 0.619 p = .001, Visual Memory Index; r = 0.657 p = < .001). However, divergent validity was limited as ChAMP Verbal Memory Index correlated with RCFT delay (r = 0.550 p = .005) and ChAMP Visual Memory Index with CVLT-C delay (r = 0.606 p = .002). Eight percent were deemed impaired on ChAMP lists delay similar to the CVLT-C delay (13%), however, ChAMP places delay identified 21% impaired, compared to the RCFT delay (42%).
ChAMP scores are strongly correlated with older established measures, but identify fewer cases as clinically impaired. This may reflect the more contemporary normative data or the fact that ChAMP tasks are less multifactorial in nature than are the CVLT-C and RCFT.
