Background and Aim: attention-deficit/hyperactivity disorder or ADHD is one of the most common problems of children and adolescents and the reason for referral to psychiatrists and psychologists. Therefore, the aim of this research was to the effectiveness of parent-child interaction training on behavioural problems and aggression of children with ADHD symptoms. Methods: In terms of the purpose, the current research design was of an applied type and in terms of the method of conducting it, it was a quasi-experimental research with a pre-test, post-test and two-month follow-up plan with the experimental and control groups. The statistical population of this study consisted of 6-10-year-old children with ADHD who were referred to a private counselling centre in the 10th district of Tehran in 1401. An available sampling method was used for sampling, and 30 people were selected, and 15 people were equally assigned to the experimental group and 15 people to the control group. In this research, the tools used included Achenbach's Child Behavior Checklist (CBCL), and Buss & Perry's (1992) Aggression Questionnaire. Parent-child interaction therapy was performed according to McNeil & Hembree-Kigin's (2010) protocol on the experimental group, but the control group did not receive any intervention. Statistical data was analyzed with spss software and using analysis of variance with repeated measurements, and Bonferroni's post hoc test was used to check the stability of the effects of the interventions. Results: F values were calculated for behavioural problems (F = 7.63) and aggression (F = 10.74). It can be concluded that the effect of the group membership factor, or in other words, the treatment of parent-child interaction, has led to a significant decrease in dependent variables (p<0.01). The results of Benferroni's post hoc test indicate that the effect of parent-child interaction therapy on behavioural problems and aggression of children with ADHD was stable. Conclusion: It can be concluded that parent-child interaction training was effective on behavioural problems and aggression of children with ADHD symptoms, and this effect was stable.

The present study aimed to investigate the effectiveness of metacognitive learning strategies in working memory among university students. This quasi-experimental research adopted a pretest-posttest control group design with follow-up. The statistical population included 268 students at Applied Sciences and Technology University in Tehran in 2022. The convenience sampling method was employed to select 30 students randomly assigned to two groups with 15 participants, i.e., the metacognitive training (experimental) and the control groups. The experimental group received 10 sessions of metacognitive strategy training based on the protocol of Wells (2011). Daneman and Carpenter's (1980) working memory test was conducted to collect data which were then analyzed using the repeated measures analysis of variance in SPSS. According to the findings, the pretest mean scores of the experimental group for storage and processing differed significantly from those of the posttest and follow-up stages (p<0.01). Furthermore, in terms of information storage and processing, there was a statistically significant difference between the mean scores of the experimental group and those of the control group (p<0.05). Thus, it can be stated that metacognitive learning strategies had a positive effect on improving the working memory of university students. University instructors can enhance students’ learning by creating conducive conditions for acquiring metacognitive strategies and fostering an engaging and appropriate educational environment.
