 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.

Aim: The Ethical and Legal Issues Self-Efficacy in Counseling (ELICSES) has been developed to evaluate counselors' and psychologists' self-efficacy in ethical and legal issues. Psychometric properties of the ELICSES in Iranian counselors and psychologists remain a largely unexplored realm. Method: The present study, therefore, seeks to translate the scale from English to Persian while also investigating the psychometric properties of the Persian version of the ELICSES. Online sampling was utilized to collect data from four hundred and forty-seven counselors, psychologists, and trainees who participated in the study. Ethical and Legal Issues in the Counseling Self-Efficacy Scale and Marlowe–Crowne Social Desirability Scale were used in the study. Results: The results of face (all items earned greater than 1.5 except one item (1.2)), content (overall CVI > 0.79, CVR > 0.62), and construct validity (CMIN=3.65, CFI=0.922, RMSE=0.45; also AVE> .5 and CR> .7) indicated that the ELICSES held appropriate validity and reliability. The results of the confirmatory factor analysis confirm the three factors of the ELICSES among Iranian counselors, psychologists, and trainees. Conclusion: These results suggested the validity and reliability of the ELICSES in evaluating self-efficacy when it comes to ethical and legal issues among Iranian counselors, psychologists, and trainees

Aim: The present study was conducted with the aim of investigating the relationship between the uses of harmful smartphones and externalizing problems with the mediating role of self-control in a sample of self-harming teenagers. Methods: The research method was descriptive-correlation type. The statistical population of the study included all teenage boys and girls of Yazd city were between July and October in 2022-23 in Yazd, Iran. Researchers selected clinics based on convenience methods and randomly selected self-harming teenagers. The data collection tool were Cell Phone Addiction Scale (CAC), Self-control Questionnaire (CSQ), and Child Behavior Checklist (CBC). Results: The results showed that the use of harmful smartphones had a direct and significant effect on aggressive behavior among self-harming teenagers (β=0.387, P=0.001). Similarly, the use of harmful smartphones had a direct and significant effect on the law-breaking behavior among self-harming teenagers (β=0.297; P=0.022). Also, self-control had a negative and significant effect on aggressive behavior (β=-0.54; P<0.01). In addition, self-control had a negative and significant effect on law-breaking behavior (β=-0.497; P<0.01). In the end, the results of the research showed that self-control had a negative and significant mediating role in the relationship between the use of harmful smartphones and externalizing problems in self-harming teenagers. Conclusion: Findings from this research indicate that teenagers who demonstrate good self-control may experience fewer behavioral difficulties and have a reduced tendency to harm themselves, regardless of their harmful smartphone usage. Findings have emphasized that greater attention should be given to assisting teenagers in developing their self-control capabilities.

Aim: The Aim of study was to investigate the effect of deception for intensity of exercise on fatigue in female students.Methods: Sixteen subjects were selected randomly among 30 students who volunteered to participate in the study and they performed maximal exercise test (Bruce) in two states. In the first state, the increase in exercise intensity during steps of Bruce test was correctly announced to the subjects, but in the second state, they were dictated that the increase in exercise intensity was less than in the first state. Dependent variables were measured at the end of the test and the data were compared with paired t-test using SPSS 23.Findings: The results showed that there was a significant difference for median frequency of rectus femoris muscle (p=0.043), maximium heart rate of the subjects at the end of Bruce test (p=0.001) and time to reach exhaustion (p=0.001) between the first state in which the actual increase in exercise intensity during steps of Bruce test was announced to the subjects and the second state in which they were dictated that the increase in exercise intensity, was less than the first state. However, no significant difference was observed for median frequency of vastus medialis (p=0.736) and vastus lateralis (p=0.762) muscles, as well as for rate of perceived exertion (p=1.000). Conclusion: According to the results, it seems that by deception for intensity of exercise during maximal exercise test, the amount of fatigue can be reduced and the time to reach fatigue can be increased.
