The study aim was to examine the relationship between acute stress disorder and job burnout among primary and secondary school teachers, and to explore the moderating effect of sense of control on this relationship. A total of 751 teachers completed self-report questionnaires during the COVID-19 pandemic. The results showed that acute stress disorder, emotional exhaustion, and depersonalization were significantly lower in female teachers than in male teachers. Age was positively associated with acute stress disorder and negatively associated with inefficacy. Acute stress disorder was significantly and positively associated with emotional exhaustion and depersonalization dimensions of job burnout. The relation between acute stress disorder and inefficacy was moderated by sense of control: acute stress disorder was positively associated with inefficacy when the sense of control was strong and was negatively associated with inefficacy when the sense of control was weak. These findings demonstrate that acute stress disorder is a risk factor for job burnout, and that sense of control is a protective factor for some aspects of job burnout. However, in individuals with a strong sense of control, acute stress disorder is associated with greater inefficacy, suggesting that sense of control can both positively and negatively affect burnout.

The COVID-19 pandemic impacts people’s mental health and behaviors, but the influence mechanism between pandemic exposure, conflict behaviors, and online aggressive behaviors during the COVID-19 outbreak remains unclear. This study will address this gap. Data were collected from 1,153 college students in an online survey that included an pandemic experiences scale, a post-traumatic stress disorder (PTSD) scale, a conflict behaviors scale, and an online aggressive behaviors scale. Structural equation modeling and multi-group comparisons were used to analyze the data. Pandemic exposure positively predicted conflict and online aggressive behaviors through hyperarousal symptoms, and negatively predicted these behaviors through intrusive symptoms. The mediating roles of avoidance and negative alterations in cognition and mood symptoms in the relations between pandemic exposure and conflict behaviors and online aggressive behaviors were non-significant. Among male students, pandemic exposure directly predicted conflict and online aggressive behaviors, but for female students, pandemic exposure indirectly influenced these behaviors through intrusive and hyperarousal symptoms. The intrusive and hyperarousal symptoms play mediating roles in the relations between pandemic exposure and conflict behaviors and online aggressive behaviors. Gender plays a moderating role in the above mediating mechanism.
