Past research has linked the symptoms of ADHD to inattention and deficiencies in processing speed and working memory. The efficacy of the Wechsler Intelligence Scale for Children (WISC) and the Child Behavior Checklist (CBCL) have been studied for screening children for ADHD, however direct correlations between WISC indexes and individual CBCL scales have not been examined in the past. The present study is aimed at finding if there is a correlation between the Attention Problems scale on the CBCL, for both parent and teacher ratings, and the Freedom from Distractibility Index (FDI)/ Working Memory Index (WMI) and the Processing Speed Index (PSI) of the WISC-111 and WISC-IV. The results indicated that for both the Full Group and the ADHD Group, there was only one significant correlation. This correlation was between the WISC-111 FDI and parent ratings of AP in the Full Group, meaning that the WISC- 111 measure of working memory is significantly correlated with parent-rated attention problems. All other correlations for the Full Group and the ADHD Group were not significant; there was no significant correlation between the WISC tests of working memory and processing speed and parent and teacher ratings of AP. The WISC and the CBCL are both very valuable tools to use with children; however, to use these as diagnostic tools, especially screening for ADHD, may not be their most effective use.
