screen time

 Objective: This study investigated the relationship between screen time and green time with academic engagement and academic performance of secondary school students in Tabriz city.Methods: The present study was part of cross-sectional and descriptive studies of the correlation and prediction type. Three hundred eighty-five people from Tabriz secondary school students were selected in the first semester of the 2022-2023 academic year by multi-stage cluster sampling based on Morgan's table. All sample members completed Reeve's academic engagement scale (AES) and Screen Time Questionnaire (STQ). The student's GPA was considered their academic performance and was evaluated by adding two questions to the research questionnaires of the green time variable. The collected data were analyzed using Pearson's correlation coefficient, simultaneous regression, and SPSS23 statistical software.Results: The results showed a negative and significant relationship between screen times, the dimensions of academic engagement, and the student's GPA. It was also found that there is a positive and significant relationship between green time and the dimensions of academic engagement (except the emotional involvement dimension) and students' GPA. Screen time and green time significantly contributed to explaining students' academic engagement and academic performance.Conclusion: The results highlighted the importance of screen and green time in educational variables.

Objective: The present study aimed to investigate the predictive model of marital relationship quality based on multi-screen addiction with the mediating role of maintenance-oriented relationship commitment in married individuals.Methods: The current research method was applied in terms of purpose, descriptive in data collection, and correlational based on the analysis process. The statistical population of the present study was the married teachers of Zanjan province in 2023, and 402 teachers participated in this research through convenience sampling. Data collection tools included the Relationship Quality Questionnaire (RQ) by Chonody et al. (2016), the maintenance-oriented relationship commitment Scale (MORC) by Schoebi et al. (2015), and the Multiple screen Addiction Scale (MSAS) by Saritepeci (2021). Data analysis was conducted using Pearson correlation tests, confirmatory and exploratory factor analyses, and structural equation modeling with SPSS 27 and AMOS 26 software.Results: The results revealed that all scales had appropriate reliability. According to the Pearson correlation matrix, there was a significant positive relationship between MORC and RQ (r=0.593, P<0.01), as well as between MSA and RQ (r=-0.237, P<0.01). Structural equation modeling also indicated a good fit of the research conceptual model with the data (RMSEA=0.074).Conclusion:It can be concluded that maintenance-oriented relationship commitment mediates the relationship between multi-screen addiction and marital relationship quality, suggesting that considering these factors in therapeutic interventions and marital enrichment programs can be beneficial.
