ABSTRACT=<sec id="sec1"><title>Background</title><p>Mandatory deployment-related quarantining added further constraints on soldiers during the pandemic. Contrary to overwhelming research documenting an adverse impact of quarantining on mental health, no adverse short-term mental health effects of pre-deployment quarantining for German soldiers were identified. Therefore, we are interested in a potentially delayed onset, the impact of an additional post-deployment quarantine, and quarantine-associated risk and resilience factors predicting mental health post-deployment.</p></sec><sec id="sec2"><title>Methods</title><p>In a prospective research design, 928 German soldiers enrolled in the study at the in-processing of pre-deployment quarantine between February 2021 and March 2022. Every German military service member undergoing pre-deployment quarantine could participate. The soldiers were between 18 and 64 years old; 87.5% identified as male and 12.5% as female. Self-reported mental health (Mini-SCL), perceived social support (FSozU-K22), and perceived unit cohesion were assessed three to five times: at the beginning and the end of pre-deployment quarantine (<italic>N</italic><sub>t1</sub> = 928, <italic>N</italic><sub>t2</sub> = 907), if still mandatory—at the beginning and the end of post-deployment quarantine (<italic>N</italic><sub>t3</sub> = 143 and <italic>N</italic><sub>t4</sub> = 132), and 3 months post-deployment, on average 7 to 8 months later than pre-deployment quarantine (<italic>N</italic><sub>t5</sub> = 308). The analyzed quarantine-associated risk and resilience factors were informedness about COVID-19, infection risk, quarantine benefit, clarity of quarantine protocol, need for intimacy/bonding, norms, stigma, practicality, financial disadvantages, boredom, and health-promoting leadership.</p></sec><sec id="sec3"><title>Results</title><p>Despite four different mental health trajectories identified, repeated measures ANOVAs revealed a significant improvement in mental health post-deployment (<italic>F</italic>[2,265] = 21.54, <italic>p</italic> &lt; 0.001), a small decrease in social support (<italic>F</italic>[2,266] = 16.85, <italic>p</italic> &lt; 0.001), and no significant changes in unit cohesion (<italic>F</italic>[2,264] = 0.482, <italic>p</italic> = 0.618) 3 months post-deployment. Using stepwise regression, 24% of variance in mental health symptomatology post-deployment is predicted pre-deployment by a clear quarantine protocol, unit cohesion, intimacy/bonding, and social support (<italic>F</italic>[4,263] = 22.23, <italic>p</italic> &lt; 0.001). In total, 30% of mental health at the end of post-deployment quarantine is predicted by stigma and a clear quarantine protocol (<italic>F</italic>[2,99] = 22.22, <italic>p</italic> &lt; 0.001).</p></sec><sec id="sec4"><title>Conclusion</title><p>Although no overall adverse impact of quarantining on mental health was found, it is recommended to address perceived stigma and clearly communicate the quarantine protocol, and to further follow up on the perceived decrease in social support.</p></sec>
