Background and Aims Executive functions, impulsivity, and working memory deficits are central characteristics of attention-deficit/hyperactivity disorder (ADHD). Many adults with ADHD respond partially to pharmacological treatments, highlighting the need for targeted psychological interventions. This study evaluated the effectiveness of mindfulness-based cognitive therapy (MBCT) in reducing impulsivity and improving executive functions and working memory in adults with ADHD. Methods This quasi-experimental study utilized a pretest-posttest design with a control group. The statistical population consisted of adults diagnosed with ADHD living in Tabriz City, Iran, during the last quarter of 2023. 30 individuals were selected through convenience sampling from two psychiatric outpatient clinics in Tabriz. Then, they were randomly assigned to either the experimental group (n=15) or the control group (n=15). The experimental group participated in eight weekly sessions of MBCT, following the protocols developed by Bowen and Marlatt. Data were collected using Bart’s impulsivity scale, Barclay’s executive functions scale, Daneman and Carpenter’s working memory test, and Canner’s adult ADHD rating scales-self-report. The data were analyzed by analysis of covariance in SPSS software, version 23. Results The results indicated that MBCT significantly improved overall executive functions (F=68.48, P<0.001) and its subcomponents (P<0.01) and impulsivity (F=53.18, P<0.001). However, it did not significantly enhance working memory in adults with ADHD (F=3.57, P=0.070). Conclusion MBCT is an effective intervention for improving executive functions and reducing impulsivity in adults with ADHD.
