Introduction
Armed conflicts and their consequences create serious obstacles to the development and prosperity of human communities. Children are especially vulnerable in these conditions, as their development at all levels—from physical to personal and social—can be disrupted. This poses particular challenges to the education system and complicates the formation in a child of a sense of safety and a basic trust in the world, which are the most important conditions for psychologically healthy development and maturation.
Traumatic experiences related to warfare have a negative impact on a child’s psyche: they increase anxiety levels, provoke the onset of post-traumatic stress disorder (hereinafter PTSD), and hinder learning and social adaptation. The prevalence of PTSD in certain samples can reach 90%, especially under prolonged exposure to a military conflict. For example, one study notes that PTSD frequency in some groups of children can be as high as 90% under long-term conflict conditions (Carpiniello, 2023).
E. Alisic emphasizes that the very concept of PTSD and most of the methods for its diagnosis were developed for adults. Meanwhile, the consequences of trauma experienced by children go far beyond PTSD, manifesting, for example, in regressive behavior, fears (including fear of losing loved ones), guilt, etc. The recovery process after trauma in children is qualitatively different: their cognitive and emotional spheres are still developing, which affects their situation appraisal, emotion regulation, and overall development. To gain a more complete understanding of the problem of childhood trauma and its consequences, Alisic suggests using various “sources” of information: assessments by the children themselves, their parents, and other significant adults such as teachers (Alisic, 2011).
M. Fennig and M. Denov analyzed children’s direct experiences, focusing on how the children themselves interpret and describe events. They showed that children affected by conflicts are not merely passive victims; they are actively coping with their traumatic experiences, using a variety of adaptation and development strategies (Fennig, Denov, 2024). The researchers point to the necessity of developing programs aimed at a child’s recovery after trauma and at fostering the child’s active stance and agency (Cavazzoni, Fiorini, Veronese, 2022).
A study involving schoolchildren in Malaysia showed that a high level of PTSD symptoms is more frequently observed in younger schoolchildren than in adolescents (Ghazali et al., 2025). In addition, younger schoolchildren affected by military conflicts have a higher risk of developing depressive disorders (Benjet et al., 2020).
I. N. Zakharova et al. studied the impact of stress experienced by younger school-aged children living in the city of Luhansk and those evacuated to other regions of the Russian Federation on their emotional and cognitive spheres. All the children examined showed signs of chronic stress. Most of the children who had not left the Luhansk People’s Republic (LPR) in the past year were found to have severe stress, with fears related to death, fire, and open combat operations. The majority of the children were afraid when receiving medical help, and were afraid of the dark and of nightmares (I. N. Zakharova et al, 2021). I. B. Ershova and co-authors also note increased fatigue, rapid exhaustion and unstable attention, reduced short-term memory capacity, and the presence of intrusive fears of injury and death (Ershova et al, 2019). Re-experiencing of the traumatic event, sleep disturbances, irritability, and heightened excitability were also observed (Ershova et al, 2017).
For children with traumatic experiences, the beginning of primary school can become especially challenging and require additional support and attention from teachers due to possible problems with attention, memory, and the ability to complete school tasks, as well as behavioral and emotional characteristics (such as obstinacy/withdrawal, conflict-proneness/unsociability, emotional instability) that arise as a consequence of the trauma (Jednaszewski, 2025).
Most authors analyzing the effects of traumatic events related to warfare on children’s psyches focus on emotional and cognitive disturbances. There is a lack of studies that take a comprehensive look at the psychological consequences of trauma experienced by a child—keeping both the multi-level negative consequences (such as manifestations of maladaptation and PTSD symptoms) and the child’s psychological coping resources in focus simultaneously, based on comparing assessments of the child’s state by significant adults.
Materials and methods
The goal of the present study was to determine the psychological consequences of traumatic experiences and the current psychological state of primary school students affected by hostilities, based on paired assessments by significant adults (parents (legal guardians or other close relatives) and teachers). The essence of this approach lies in using complementary evaluations from these two groups, who observe the child in different spheres of personal functioning. This approach allows for mass screening of children’s status without their direct participation in diagnostics, in order to organize subsequent targeted assessments of those children who, based on the adults’ evaluations, turn out to be at risk.
The research hypotheses were: 1) The content of traumatic experiences and their psychological consequences in children of grades 1–4 differ depending on the extent to which their places of residence are or were involved in the consequences of hostilities. 2) Assessments by significant adults are informative regarding the severity of maladaptation manifestations, signs of post-traumatic stress disorder (PTSD), and the child's psychological coping resources; they are complementary to each other and can be used for screening the condition of younger school-age children who have been affected to varying degrees by military actions.
The study employed questionnaires for parents and teachers that were developed on the basis of a Screening Methodology for assessing the condition of children affected by hostilities (hereinafter “screening methodology”). These questionnaires are aimed at evaluating indicators of the child’s maladaptation in five fundamental spheres of personal functioning: psychophysiological, emotional, cognitive, behavioral, and communicative, as well as composite indicators of overall maladaptation and of the child’s psychological resources for coping with stress. The criteria for the levels of maladaptation in the applied screening methodology include: Level I: 1,0 point – no manifestations of maladaptation (norm); Level II: 1,01–2,0 points – isolated symptoms and signs of maladaptation (mild maladaptation); Level III: 2,01–3,0 points – moderate signs of maladaptation (moderate maladaptation); Level IV: 3,01–4,0 points – pronounced signs of maladaptation (Ulianina et al, 2024).
Parents used the parent version of the screening methodology to describe their children’s condition, and teachers used the teacher version. The differences between the versions concern the setting in which the child is evaluated: at home vs. at school. Parents were also presented with a list of events (developed for this study) to inventory the child’s traumatic experiences both related and unrelated to hostilities, as well as the Parental Questionnaire for Assessing Children’s Traumatic Experiences (Tarabrina, 2001). This questionnaire includes scales reflecting the severity of manifestations according to individual PTSD criteria: A (experiencing intense emotions caused by a serious threat to life or health), B (intrusive re-experiencing of the trauma), C (avoidance of stimuli subjectively associated with the traumatic events, and avoidance of activities that were previously appealing), D (presence of arousal symptoms that were not present before the traumatic event), F (impairment in several significant areas of life functioning), as well as a total score summarizing criteria B through F. For this study, the following cut-off values were proposed for categorizing levels based on the total PTSD score: 0 points – no PTSD symptoms (Level I); 1–15 points – presence of some PTSD symptoms (Level II); more than 15 points – multiple PTSD symptoms (Level III).
Analysis was conducted using IBM SPSS Statistics 27.0. The following statistical methods were applied:
-
Descriptive statistics: number of respondents and prevalence of potentially traumatic events in the child’s experience, by region (%).
-
Nonparametric tests: 1) Paired comparisons of parent and teacher evaluations were performed using the Wilcoxon signed-rank test for related samples; 2) Prevalence of traumatic events by region, inter-regional comparisons of the prevalence of traumatic experience, levels of maladaptation, and PTSD were performed using Pearson’s χ² test.
-
Correlation analysis: Spearman correlation coefficients were calculated between (1) the maladaptation and psychological resource indicators obtained from parent (legal guardian) and teacher assessments, and (2) the maladaptation and psychological resource indicators from parent and teacher assessments and the PTSD criteria/overall index, as well as the composite indicators reflecting the children’s traumatic experience.
Results
A total of 2524 pairs of significant adults participated in the study, assessing children aged 6 to 12 years in grades 1–4. The pairs consisted of parents (or other legal representatives; hereafter all referred to as “parents”)—among them 2399 identified as the mother, 81 as the father, and 44 as other family members of the student—and the homeroom teachers of elementary school classes.
In LPR (Luhansk People’s Republic; 644 pairs), Zaporizhzhye region (222 pairs), Kherson region (446 pairs), and Bryansk region (342 pairs), the study participants were teachers and parents of children who had suffered as a result of hostilities. In the Republic of Crimea (255 pairs), the participants were teachers and parents of minors who were among the internally displaced from territories of active fighting as well as from neighboring countries. In Kemerovo oblast – Kuzbass (615 pairs), among others, data are presented on the condition of children from families of participants (veterans) of the special military operation.

The most common type of traumatic experience unrelated to hostilities was parents’ divorce, as well as loss of contact/breakup with friends. Among the potentially traumatic events related to hostilities, the most frequently mentioned were: being in a firing zone, seeing/hearing explosions, hiding in a shelter, and forced displacement.
Out of the 2524 children for whom responses were obtained from both teachers and parents, 50,4% have some traumatic experience (N = 1272). In 40,6% of the total number of children, this experience was in some way related to hostilities (N = 1031).
The results of a comparative analysis of children’s maladaptation indicators based on the teacher and parent questionnaires—which allow assessment of the degree of similarity or divergence between teachers’ and parents’ evaluations of the child’s maladaptation and the presence of psychological resources in each child—are presented in Table 3.

It was found that the only relative agreement between parent and teacher evaluations of children’s maladaptation was in the behavioral sphere. The observed discrepancies in evaluations concerning maladaptation in the other spheres are expected, since teachers assess the child during social interactions with peers and teachers, whereas parents assess the child in an informal family setting.
The interrelations between the severity of maladaptation manifestations and the children’s psychological resources, as obtained from the surveys of teachers and parents, are presented in Table 4.

Note: «**» — correlation is significant at the p < 0,01 level (two-sided), «ос» — small correlation significance (0,1-0,3), «с» — medium correlation significance (0,31-0,5), by the Cheddock scale.
Owing to the large sample size, all correlation coefficients turned out to be highly significant, so effect sizes were calculated using Cheddock’s scale. Statistically significant (predominantly small and moderate) correlations were found between the evaluations by significant adults of the children’s maladaptation manifestations and psychological resources. Higher indicators based on parent evaluations corresponded to higher indicators based on teacher evaluations.
Based on the criteria for classifying different levels of maladaptation proposed above (see “Materials and Methods” section), we analyzed the distribution of maladaptation levels among children in the studied regions according to parent evaluations (Fig. 1) and teacher evaluations (Fig. 2). Differences in the distribution of maladaptation levels by region show a greater level of statistical significance according to the data from teacher evaluations (χ² = 46,942, p ≤ 0,001) than according to parent evaluations (χ² = 25,815, p ≤ 0,040).
Fig. 2. The levels of maladaptation of students, based on version of screening instrument for teachers
To assess the intensity of traumatic experiences and PTSD symptoms in the children, the “Parental Questionnaire for Assessing Children’s Traumatic Experiences” was used (Tarabrina, 2001). The criteria for categorizing levels are presented in the Methods section. The levels of severity of PTSD symptoms in the children are shown in Fig. 3.
Among students from LPR and Kuzbass, in more than 50% of cases parents reported no PTSD symptoms in the children, and the number of identified cases of pronounced PTSD symptoms was around 2%. In contrast, the results of parent questionnaires for students in Zaporizhzhya, Kherson, Bryansk regions, and Crimea indicated a predominance of children with some PTSD symptoms. The percentage of children with multiple PTSD symptoms in these regions was also higher. The differences in the distribution of PTSD symptom severity levels by region are statistically significant (χ² = 71,860, p ≤ 0,001).
Finally, we examined the interrelations between the severity of the child’s PTSD symptoms, maladaptation, and personal psychological resources for coping with stress on the one hand, and the composite indicators reflecting the presence and “variety” of traumatic experience the child has lived through on the other. The results of the correlation analysis using Spearman’s coefficient are presented in Table 5.

The results indicate that the composite indicators of traumatic experience, both related and not related to hostilities, have significant (predominantly small and moderate) positive correlations with virtually all the metrics of the instruments used to assess children’s maladaptation and the severity of PTSD symptoms. In other words, greater trauma exposure is accompanied by increased manifestations of maladaptation and PTSD.
Discussion of results
The traumatic experiences of primary school students living in territories that have been affected to varying degrees by hostilities can be conditionally divided into those related to hostilities (being in a shelling zone or in immediate proximity to it, loss of loved ones, destruction/loss of home) and those unrelated to hostilities (parents’ divorce, loss of social ties). The high percentage of children with such traumatic experiences, as revealed by the parent survey, points to the significance of the problem; however, it does not fully reflect its scale, since the questions asked were about the types of events (multiple choice from a given list), not their frequency.
The study of regional differences in the severity of maladaptation and PTSD manifestations showed that children in Zaporizhzhye, Kherson, Bryansk regions and Crimea have a higher prevalence of maladaptation manifestations and PTSD symptoms than children in LPR and Kuzbass. It is important to note that in Crimea the participants were students who moved to the republic from regions affected by hostilities, fleeing shelling and destruction. Kuzbass is the only region in this study geographically distant from the war zone, so the lower levels of maladaptation and PTSD manifestations were expected. At the same time, the relatively low levels found in children from LPR may reflect a habituation effect under conditions of prolonged living in close proximity to a combat zone.
The correlation analysis results showed significant positive relationships between the composite indicators of children’s traumatic experience and the severity of their maladaptation and PTSD symptoms. Thus, greater trauma exposure is accompanied by heightened maladaptation and PTSD manifestations. In contrast, the children’s psychological resources are negatively correlated with the volume of traumatic experience, which confirms their buffering role in mitigating its negative effects. At the same time, the trauma experienced by the child depletes the child’s psychological resources, reducing the effectiveness of coping with traumatic events.
The analysis of parent and teacher assessments revealed statistically significant discrepancies in the perceived severity of children’s maladaptation signs in most spheres. However, the correlation analysis indicates that high parent ratings correspond to high teacher ratings, and vice versa. It was also found that teachers rate the manifestations of children’s maladaptation in other spheres of functioning lower than parents do.
Considering the child’s maladaptation through the eyes of significant adults allows one to see the child’s state and functioning from different angles and in different conditions: teachers observe children in the process of learning and interacting with peers, while parents observe them in a family and informal setting. Furthermore, teachers are focused on the children’s educational and social development aspects, whereas parents are more sensitive to emotional and personal manifestations. The evaluation of a child’s psychological resources by significant adults may need to be adjusted for social desirability; however, such evaluations can be relied upon when analyzing cases of markedly deficient or insufficient resources. The presence of such a deficiency—combined with pronounced signs of maladaptation—should serve as a warning signal for the teachers and psychologists working with these children.
Research designs for assessing children’s condition, including those based on evaluations by parents and teachers, have been proposed by other authors as well (Alisic, 2011). The present study has shown that a rapid assessment of the condition of children affected by hostilities can be carried out based on expert evaluations by significant adults. These assessments make it possible to identify risk groups, which include children with Level IV maladaptation and Level III PTSD symptom severity, who require professional attention and in-depth individual diagnostics. However, these assessments do not allow for a comprehensive understanding of the prevalence of maladaptation and PTSD manifestations in younger schoolchildren affected to some degree by hostilities.
Conclusion
Our study revealed that children who have experienced the consequences of hostilities face a wide range of traumatic events. Most often, children see and hear explosions and find themselves in shelling zones. Such experiences were found to be closely associated with manifestations of maladaptation and PTSD in the child, while simultaneously depleting the child’s psychological resources that are necessary for effective coping with stress.
The negative consequences of the traumatic experiences were evaluated by a pair of significant adults (a teacher and a parent) in the contexts in which they observe the child—at home and at school. This approach allows one to assess how similar the child’s adaptive/maladaptive behaviors are across settings, and whether they are situation-specific or pervasive. PTSD manifestations, however, were evaluated only by the parents/legal guardians. Although the obtained figures are substantially lower than those reported by other authors, they indicate a need for psychological assistance and for the development of assessment tools that can be used in mass examinations of children.
The results of our study provide a general picture of the spectrum of traumatic events children experience, the severity and prevalence of maladaptation and PTSD manifestations, and the psychological resources the child has for coping with stress that mediate the negative impact of traumatic events. These findings support the utility of a design that relies on surveys of significant adults—parents/legal representatives and teachers working with the children—for conducting a screening assessment of the psychological state and psychological consequences of traumatic experiences in younger school-age children related to hostilities.
It is important to take these data into account when developing targeted psychological assistance programs for children who have experienced trauma related to hostilities, considering both the degree of involvement of the region of residence in the consequences of hostilities and the severity of the diverse psychological consequences observed in the child.
Prospects for further research may be associated with: (1) taking into account actual data on the intensity of hostilities in the child’s area of residence at the time of assessment; (2) considering the family situation and health status when analyzing the psychological consequences of the traumatic experience; (3) in-depth study of the characteristics of the traumatic experience, maladaptation manifestations, and psychological coping resources; (4) evaluating the dynamics of children’s state who have been affected to some degree by hostilities; (5) considering the psychological state of the significant adults and their role in the process of coping with the traumatic experiences of children in this age group.
Limitations. The study was based only on assessments of significant adults, objective indicators (academic success, data on behavior and general health of students, etc.) were not taken into account.
