Abstract :

    Mindfulness is effective via transdiagnostic mechanisms such as planning. The aim of this study was to evaluate the impact of mindfulness meditation training on planning function of female adolescents with subthreshold symptoms of attention deficit-hyperactivity disorder (ADHD) in Tower of London Test (TLT). The current study was experimental including pretest-posttest design with control group. The statistical population of this study was all female adolescents (13 to 15 years) with subthreshold ADHD symptoms that after screening, 30 subjects as the members of sample were randomly assigned to the treatment group (n = 15) and control group (n = 15). Mindfulness meditation practices was presented to the treatment group in 8 sessions of 90 minutes during 8-week however, the control group received no training. TLT was performed on both groups before and 1 month after intervention. The results of one-way analysis of covariance showed that the planning function of the treatment group in TLT was improved significantly (p<0.05) in number of correctly solved items and percentage correct score in 1 month after intervention relative to the control group with large effect size however, there was no significant difference between two groups in planning time and total time in 1 month after intervention. Totally, mindfulness meditation training improves the planning function in TLT in subthreshold ADHD female adolescents. Treatment development efforts should target clinical populations that exhibit difficulties in this transdiagnostic mechanism.
