| Attention-Deficit/Hyperactivity Disorder (ADHD) is often regarded as a disorder of childhood and adolescence, but it affects millions of adults each year. For adults the symptoms of ADHD can include inattention, impulsivity and a poor working memory. Computerized cognitive working memory training has previously been used with children and adolescents with ADHD to see how it affects their symptoms with some success; however, this work had not been done yet with adults with ADHD. This study used a quantitative quasi-experimental design with an experimental group and a wait list control group to look at the effects of working memory training on ADHD symptoms on a sample of adults with ADHD. All participants met with this researcher for pretest and posttest measures, which consisted of two subtests from the Wechsler Memory Scales III (Spatial Span Board and Letter Number Sequencing) that were combined as one measure, and the overall ADHD score on the Attention of Variable's Test (TOVA) as a second measure. The experimental group used a computerized working memory training program for a period of five weeks (or 25 sessions) in their homes. A MANOVA was used to look at within and between group differences on post test scores. A statistically significant improvement in working memory scores was seen in the experimental group from pretest to posttest. An improvement on TOVA scores was also seen, but not to a statistically significant degree. |
