The objective of the present study was to examine the relationship among sleep disorders, executive dysfunction, and sluggish cognitive tempo in adolescents utilizing a network approach. The study was performed based on descriptive-correlation method. The population of study contained all the adolescents (ages 12-18 years) in Tehran, Ardebil, Southern Azerbaijan and Western Azerbaijan provinces during 2021-2022 academic year. Data were collected from Two thousand six hundred and fifty-nine adolescents who were recruited through convenience sampling method. Participants completed the Adult Concentration Inventory (Becker et al. 2015), Sleep Disorders Symptom Checklist (Klingman et al. 2017), and Executive Skills Questionnaire-Revised (Strait et al. 2019). The bootnet package in R software used for data analysis. Results showed Sluggish Cognitive Tempo (SCT) was positively and more closely related to Sleep Disorders (insomnia) than Executive Dysfunction. the results showed that the most robust relative bridge connections were Sluggish Cognitive Tempo (SCT) and Plan Management (PM), edge weight = 0.33; Sluggish Cognitive Tempo (SCT) and Insomnia edge weight = 0.26; in addition to the positive bridge connections, a negative robust connection was also recognized between Obstructive Sleep Apnea (OSA) and Emotional Regulation (ER), edge weight = - 0.07. In conclusion, Sluggish Cognitive Tempo (SCT) was positively associated with sleep disorders and executive dysfunction. Future interventions may be developed that emphasize the bridge connections of sleep disorders, executive dysfunction, and sluggish cognitive tempo in adolescents

The main aim of this study this study was explaining the structural model of teacher's perception of school's social capital and teacher's psychological capital with their readiness for change in primary schools. The research statistical population was included all primary school teachers (17500) in Fars province, that 733 of them were selected as the research sample by using systematic sampling method. The research instruments were included three questionnaires: social capital, psychological capital and readiness for changing, which were distributed and collected after calculating validity (speciation analysis) and reliability (Cronbach's alpha). Research data were analyzed using one-sample t-test, Pearson's correlation's matrix and multivariate regression (structural equation model) and also Amos23 and Spss25 software. Findings showed that while the average dimension of social network was higher than the desired level, the rest of the dimensions of social capital and the average total of social capital was less than the desired level. The average of teacher’s psychological capital and all its dimensions was higher than desired. Examining the simultaneous role of social capital and psychological capital in predicting readiness for change, it was concluded that social capital loses its predictive power for readiness for changing (β= 0/07 & p= NS) and psychological capital have a positive and significant predictive power for readiness for change (β= 0/62 & p< 0/01). The output of this research can be use by managers, teachers and other staff in different domains to providing readiness ground for change by developing and strengthening the capacities of psychological capital.
