Abstract
The aim of this research was to investigate the executive functions in two groups of individuals with opioid-dependent, amphetamine- dependent and to compare them with the executive functions in the individuals of the control group. Executive functions were investigated in 4 sub-scales including working memory sustain attention, inhibitory control and planning. To do so, 90 participants were selected via simple nonrandom or convenience sampling. Of these participants, 30 individuals were opioid-dependent, 30 individuals were amphetamine dependent and 30 individuals were healthy. Subjects of the study were evaluated using color-word Stroop, Wisconsin card sorting, continuous performance and digit span sub-scale test. The results of one way analysis of variance indicated significant deficits in amphetamine dependent group in 4 sub-scales of executive functions, but opioid dependent individuals had deficits in inhibitory control and planning compared to the control group. As a result, there were more deficits in the executive functions of amphetamine group in comparison to the opioid-dependent and control group. There were fewer deficits in the opioid-dependent group in comparison to the Amphetamine- dependent group.

Abstract
The aim of the current study was to examine the effectiveness of cognitive behavioral group therapy based on executive functions in improving the executive functions in students with Attention Deficit / Hyperactivity Disorder (ADHD). This study was carried out in 2011-2012 academic year using pre-post- test design with a control group. Students of Mashhad’s Ferdowsi University who were previously diagnosed with ADHD or who were showing the symptoms of ADHD at the time of the study were invited to participate in this study. Primary diagnosis was based on the Barkley Adult ADHD Rating Scale—IV (BAARS-IV) and final diagnosis of the disorder was done through psychiatric interview. Finally, 32 students were selected as the subjects of the study and were randomly divided into a control and an experimental group. The experimental group received EF based cognitive-behavioral group therapy. In addition to BAARS-IV all participants completed Barkley Deficits in Executive Functioning Scale (BDEFS) at pre-post-test assessments. Results of MANCOVA & ANCOVA tests showed that participants in the experimental group improved their executive functions including time management, planning, organization, self-motivation, and emotional self-regulation. Results of the study demonstrated that EF based cognitive-behavioral group therapy was effective in improving the executive functions in student with ADHD. Therefore, along with other treatments this treatment can be used as a modern approach for improving the executive functions of students with ADHD.
