The purpose of this research was the effectiveness of mindfulness training on executive functions (working memory and attention) and self-efficacy in patients with anxiety disorders. The sample of this research included 30 people from the mentioned community who were selected by available sampling method. 15 people in the experimental group and 15 people in the control group were randomly divided. The research design was semi-experimental with pre-test-post-test with control and experimental groups. The measurement tools included Gioia et al.'s executive function questionnaire (2000) and Scherer's general self-efficacy. To implement, at first, a pre-test was taken from both groups. Then the experimental group underwent mindfulness intervention during 8 sessions of 90 minutes, then a post-test was taken from both groups. Data analysis was done using multivariate covariance analysis (MANCVA) and one-way covariance analysis (ANCVA). The results of the research showed that mindfulness training has a significant effect on executive functions (working memory and attention) and self-efficacy of patients with anxiety disorders.

The aim of this study was to investigate the effectiveness of mindfulness training on time perspective, time metaphorical perception, and Internet addiction. The study used a quasi-experimental pretest-posttest design with a control group. The statistical population included all students of Payam Noor University- Alborz Province (Karaj branch), in 2025. In this study, 50 students from Karaj branch, were selected through convenience sampling, and randomly assigned to two experimental groups (25 people) and control group (25 people). Research tools included Zimbardo and Boyd's Time Perspective Inventory, Raiisi and the Moghadasins' Time Metaphorical Perception Questionnaire, and Young's Internet Addiction Questionnaire. The mindfulness training protocol was implemented on the experimental group in eight 90-minute sessions, and the control group did not receive any intervention. The results of mixed analysis of variance showed that mindfulness training had effects on the means of time perspective, time metaphorical perception, and Internet addiction in the experimental group during the time (P<0.01). It seems that the use of mindfulness-based educational interventions can be an effective solution for managing and viewing time and solving Internet addiction problems in university students.
