Differences in military personnel's hardiness depending on their leadership levels and combat experience: An exploratory pilot study.

Constant challenges and permanently stressful conditions at military workplaces demand high levels of hardiness for military personnel. We aimed to determine possible differences in Ukrainian military personnel's hardiness depending on their leadership levels and existing combat experience. The study involved 543 Ukrainian service members (85.8% male and 14.2% female, aged 18 to 61 years). We used the Professional Hardiness Questionnaire and the Brief Resilience Scale. The obtained data showed that the higher leadership levels the military personnel had, the higher their hardiness was (up to the company commander level in our study). We revealed a significant predominance of professional challenge acceptance in the structure of military personnel's hardiness, followed by professional control and professional commitment. This proportion of professional hardiness components did not differ depending on service members' leadership levels. Additionally, we showed significantly higher hardiness stability after participating in combat operations in military leaders compared to service members without subordinates. Our findings necessitate hardiness examination during military personnel selection and its development during military training, in particular for deployment.

Military personnel's stress reactivity during pre-deployment in a war zone.

Many studies have been conducted on the numerous negative post-deployment outcomes for military personnel. However, data on service members' pre-deployment stress reactivity are absent. This is a serious gap in existing research, as stress has an important regulatory role. This study aimed to determine possible manifestations of military personnel's stress reactivity during pre-deployment in a war zone in eastern Ukraine. The study involved 270 Ukrainian service members (all male, aged 18 to 58 years). Sample 1 (n = 108) were preparing to be deployed for the first time, sample 2 (n = 84) were preparing to be deployed and had previous experience of deployment, and sample 3 (n = 108) were not preparing to deploy and had no previous deployment experience. We used the Ukrainian adaptation of the Giessen Subjective Complaints List (GBB-24), the Symptom Checklist-90-Revised (SCL-90-R), the Short Screening Scale for DSM-IV posttraumatic stress disorder and the Combat Exposure Scale (CES). We found that indicators for physical complaints, psychological problems and psychopathological and posttraumatic symptoms among service members from samples 1 and 2 were significantly higher than those of sample 3 in 15 of 18 cases (p < 0.001-0.05). The indicators obtained for sample 2 were higher than those of sample 1 in six of nine cases (p < 0.001-0.05). Both our study hypotheses were confirmed. The present findings can be used to develop efficient psychological interventions for military personnel during pre-deployment in a war zone.
