Thesis:

Strukturelles Modell der Beziehung zwischen akademischem Aufschieben und Arbeitsleistung mit Angst, die vermittelnde Rolle der Selbstregulierung bei Krankenpflegeschülern in der Stadt Sabzevar.

Objective: The aim of this study was to investigate the structural relationship between academic procrastination and job performance with anxiety, considering the mediating role of self-regulation, among nursing students in Sabzevar. Methodology: This research adopted a descriptive-correlational (survey) approach with an applied objective. The statistical population included all 214 female nursing students at Sabzevar University during the academic year 2024–2025. Based on Morgan’s table, a sample of 160 students was selected using random sampling. Data collection instruments included the Beck Anxiety Inventory (1990), Tuckman Academic Procrastination Scale (1989), Paterson Job Performance Questionnaire (1970), and Zimmerman and Pons’ Student Self-Regulation Questionnaire (1988). Data analysis was performed using SPSS version 22 and PLS version 3 software. Findings: The results indicated that both academic procrastination and job performance have a significant indirect effect on nursing students’ anxiety, mediated by self-regulation. Furthermore, the following direct relationships were found to be significant: • A positive relationship between academic procrastination and anxiety. • A negative relationship between academic procrastination and self-regulation. • A negative relationship between job performance and anxiety. • A positive relationship between job performance and self-regulation. • A negative relationship between self-regulation and anxiety. Conclusion: Self-regulation serves as a crucial mediating mechanism, playing a key role in explaining the relationship between the study variables. .
