1. Introduction
Currently, the main duty of military personnel is to maintain peace, defending their nation even with their lives if necessary [
1]. Among their virtues are readiness, obedience, and accuracy, driven by honor and love for service, as well as the desire to face risky and fatiguing situations [
2]. These pressures can lead to psychological and social issues, affecting intrapersonal and interpersonal competencies [
3], due to stressors [
4]. Since the wars in Afghanistan and Iraq, the Armed Forces have implemented initiatives to enhance psychological resilience and prevent morbidity in over one million soldiers [
5]. Members of the Armed Forces must have a solid psychological foundation to manage adverse situations throughout their military careers and maintain good mental health [
6].
In Spain, the Armed Forces (FAS), composed of the Army (ET), the Navy, and the Air Force, have an appropriate organization and structure for national defense and security [
7], as a result of the modernization process at the beginning of the 21st century when it joined the North Atlantic Treaty Organization (NATO), aligning with the emerging Common Security and Defense Policy of the European Union [
8].
However, to provide an efficient response by military personnel, training in social skills and emotional competencies is required to aid in emotional management and proper coexistence [
9]. Therefore, it is crucial that military training centers promote ethical principles and standards and develop psychological variables such as resilience and emotional intelligence to improve the professional performance of their members [
10].
Resilience in Military Personnel
The relationship between resilience and its influence on military personnel has become a subject of research in recent years, as the modern combatant faces significant physical and psychological challenges [
11]. Resilience, traditionally linked to morale, has been crucial for the military, as its success in operations depends on it [
12]. The term resilience can be defined as the ability to face adverse situations, grow from them, and prevent them from affecting one’s core [
13], and it can be measured by the absence of post-traumatic stress disorder (PTSD) [
14]. Military personnel with a resilient profile actively seek social support and maintain high self-esteem, which allows them to adapt to their environment in a positive way [
15].
Moreover, an adequate level of resilience is necessary for military personnel to cope with the various stressful situations they encounter in their daily lives [
16]. In fact, a high resilience score is negatively correlated with burnout syndrome [
17]. This syndrome, caused by high levels of stress and low perceived social support, leads to emotional exhaustion, sleep disorders, apathy, and depressive symptoms (feelings of hopelessness and lack of self-confidence), as revealed by Maddah et col. [
18]. At the same time, resilience is also closely related to emotional intelligence (EI), as it has a direct effect on it [
19] and predicts self-efficacy, influencing the relationship between stressors and their outcomes [
20,
21]. According to White et col. [
22], high levels of resilience and emotional intelligence can protect against the symptoms of burnout.
Emotional Intelligence in Military Personnel
Emotional intelligence can be understood as the combination of skills, competencies, abilities, and attitudes that determine an individual's behavior, mental state, or reaction to various situations, in a way that favors the peaceful resolution of problems arising from emotions and promotes overall development, including the ability to recognize both one’s own feelings and those of others [
23]. Authors such as Bar-On [
24] suggest that emotional intelligence consists of mental capacities related to the processing of emotions, as well as personality dimensions such as assertiveness, empathy, and optimism, along with mental and emotional capabilities. Specifically, emotion appears alongside cognition and motivation as an essential element for personal development and optimal performance [
25]. The concept of emotion has evolved beyond the traditional focus on anxiety and depression, highlighting the benefits it provides throughout an individual’s life, shaping their adaptive skills and overall well-being [
26].
According to Goleman [
23], the components that make up emotional intelligence are: 1. Self-awareness (recognizing one’s own emotions); 2. Self-regulation (managing one’s own emotions); 3. Self-motivation (motivating oneself to achieve goals); 4. Empathy (recognizing the emotions of others); 5. Social skills (building good relationships). These components are interrelated and facilitate the emotional process, representing a significant factor in life satisfaction, especially in married individuals [
27]. Its importance lies in the fact that emotions drive human behavior, making emotional intelligence a predictor of future success that should be fostered by institutions [
28]. Emotional intelligence is a learned ability that can be developed through education in self-perception, self-regulation, self-motivation, empathy, and social skills contributing to personal, social, and professional well-being [
30,
31].
In particular, a high level of emotional intelligence in service institutions is linked to better performance in these services [
32]. The emotional state of workers influences their behavior and professional performance, becoming increasingly relevant in organizations [
33]. Emotional intelligence is negatively associated with stress, depression, and negative emotions [
34], and positively associated with motivation [
35]. The development of emotional competencies, such as empathy, promotes cooperative work [
36]. In turn, a high level of emotional intelligence enhances psychological and social functioning, optimizing cognitive, social, emotional, and behavioral processes [
37]. Authors like Corzine et col. [
38] point out that overcoming emotional deprivation increases the capacity for recovery in difficult situations, allowing for successful handling of adverse scenarios [
39]. In addition, Umucu et col. [
40] report that a high level of resilience in military personnel is associated with greater optimism, as well as emotional intelligence, conflict resolution skills, and higher self-esteem, which reduces anxiety, depression, and the risk of PTSD [
41].
The Present Study
Currently, military institutions must promote the development of resilience and emotional intelligence in their members [
42,
43] to improve their coping capacity in adverse situations [
44] and enhance their well-being [
45]. However, no study has yet analyzed the relationship between the marital status of military personnel and their level of resilience and emotional intelligence. Therefore, the main objective of this study is to analyze the psychological variables of resilience and emotional intelligence in Spanish Army personnel and their relationship based on marital status. Specifically, the study aims to: a) establish the relationship between resilience and marital status; b) analyze profiles or groups according to resilience and emotional intelligence levels and marital status; c) identify the predictive role of resilience on emotional intelligence. The initial hypotheses previously outlined for this study are as follows (
Figure 1):
Hypothesis 1 (H1): There are positive relationships between resilience and emotional intelligence; H2: There are no mean differences based on gender and levels of resilience and emotional intelligence; H3: Military personnel who are widowed show lower levels of resilience and emotional intelligence compared to those who are single, married, or divorced/separated; and H4: Resilience is a predictor of emotional intelligence.
3. Results
Firs,
Table 1 presents the results for the sociodemographic variables, where
n = 410 (55.5%) fell within the highest age range of 26-35 years, while
n = 1 (0.1%) was in the age group over 65 years, which in this case, represented the lowest. Regarding marital status,
n = 387 (52.4%) were single, followed by
n = 294 (39.8%) who were married,
n = 44 (5.9%) who were divorced/separated, and finally, n = 14 (1.9%) who were widowed.
On the other hand,
Table 2 presents the correlations found between resilience and emotional intelligence and the factors and components that make up emotional intelligence. The results show statistically significant positive correlations (
p < .05) or very significant correlations (
p < .01) in most relationships.
Regarding the mean differences (
Table 3), the t-test results showed no statistically significant differences between men and women in terms of resilience (
t = .46;
p = .642;
d = .05) nor in emotional intelligence (
t = 1.36;
p = .171;
d = .15). However, statistically significant mean differences were found based on gender in the Stress Management component (
t = 2.85;
p < .05;
d = 0.31), with men showing a higher level (
M = 12.41;
SD = 2.48) compared to women (
M = 11.61;
SD = 2.63), as well as in General Mood (
t = 2.78;
p < .05;
d = 0.32), where the male gender also showed a higher mean (
M = 12.89;
SD = 2.49) compared to the female gender (
M = 12.07;
SD = 2.63).
The results showed a significant effect according to the post hoc Turkey test regarding the overall resilience level (
F = 7.73;
p < .001;
η² = .030) and overall emotional intelligence (
F = 4.17;
p < .01;
η² = .016) across the different groups: single, married, divorced/separated, and widowed. In all cases, it was the widowed military personnel who showed the lowest mean in both resilience factors and the five components of emotional intelligence, as can be seen in the following
Table 4:
Figure 2 illustrates that it is the widowed military personnel who report the lowest levels of both overall resilience and emotional intelligence. In terms of resilience, they are followed by divorced/separated personnel, married personnel, and finally, single personnel, who present the highest level. However, in emotional intelligence, after widowed personnel, the divorced/separated group is followed by single personnel, and lastly, married personnel, who exhibit the highest levels.
The summary of the model obtained in the two-step cluster analysis identified a total of 4 clusters, where the cases were classified based on their scores in resilience and emotional intelligence. The first cluster (c1), with 39.6% of the cases (
n = 59), was characterized by scoring below the sample mean in both resilience and emotional intelligence. This was followed by cluster c2 (
n = 153), with 31.7% of the cases, cluster c3 (
n = 293), with 20.7% of the cases, and finally, cluster c4 (
n = 234), with 8% of the cases, as shown in the following
Figure 3:
The regression analyses resulted in a model where resilience explains 15% of the variance in emotional intelligence (R² = .15). The results of the linear regression indicated that resilience has a positive impact on emotional intelligence (B = 1.13; SE = 1.09). The coefficients for the predictor variable were greater than 0.05, and the p-values were less than 0.05. The standardized effects of resilience on emotional intelligence were statistically significant and supported (β = 0.39; t = 11.69; p < .001). The Durbin-Watson statistic confirmed the validity of the model (D = 1.98).

Regarding the t-statistic, an association with an error probability lower than 0.05 was found for the variables in the model: resilience on emotional intelligence. The absence of multicollinearity between the variables was confirmed by low tolerance values and high VIF values.
4. Discussion
The results obtained have allowed for the achievement of the general objective set out in this study, which was to analyze the psychological variables of resilience and emotional intelligence in military personnel of the Spanish Army and their relationship based on marital status. Resilience was found to be positively related to the level of emotional intelligence. Being widowed seems to negatively affect the presence of higher levels of resilience and emotional intelligence in military personnel, which results in poorer coping with stressful situations [
42] and worse emotional regulation [
45]. This could be associated with the presence of PTSD [
41], lower optimism [
40], and a reduced ability to recognize, manage, and self-motivate emotions, as well as empathize and demonstrate prosocial behaviors [
23]. These factors could negatively impact their professional performance [
32,
33,
36].
Regarding the first specific objective of this study, the results report a positive relationship between resilience and emotional intelligence, consistent with findings in other research lines [
20], thus supporting the first hypothesis. This suggests that increasing resilience levels positively influences emotional intelligence. Consequently, higher levels of these psychological variables could prevent the onset of emotional burnout in military personnel [
17,
22] and facilitate better adaptation to different contexts they may [
15], promoting higher levels of perceived social support and lower levels of stress and depression [
18,
34]. On the other hand, in response to the second hypothesis of this study, no significant differences were found in the mean scores for gender and overall resilience or overall emotional intelligence in the t-tests, nor in any of the factors that make up these instruments. Therefore, this second hypothesis is confirmed. This suggests that the current Spanish Army provides educational resources that support the development of psychological strategies to mitigate the underlying effects of stressors related to military service [
4].
Regarding the third research hypothesis, the results obtained in the MANOVA analysis indicate that military personnel who are widowed show lower levels of resilience and emotional intelligence compared to those who are single, married, or divorced, supporting this third hypothesis. In this regard, although there is a lack of previous studies related to this line of research, Corzine et col. [
38] suggest that this could be a consequence of the absence of the spouse’s emotional support, which may negatively impact both the resilience and emotional intelligence of military personnel [
44].
In this direction, it could be inferred that military personnel who are widowed may exhibit lower self-confidence, independence, strength, invincibility, wit, perseverance, and less flexible thinking compared to those with other marital statuses, as well as behavioral patterns of maladaptation [
48]. Furthermore, effective problem-solving may be impaired, as they tend to have a less optimistic attitude [
50]. Tsirigotis [
37] suggests that a good level of emotional intelligence would allow military personnel to optimize cognitive, social, emotional, and behavioral processes, improving not only their psychological functioning but also positively impacting their interpersonal relationships.
Through cluster analysis, four profiles were identified in relation to emotional resilience and resilience, addressing the second specific research objective. On the one hand, the first cluster is made up of military personnel who are widowed, showing lower scores on the psychological variables studied. The second cluster consists of military personnel who are separated or divorced, and in this case, they show higher levels than those who are widowed. The third cluster consists of those who are single, who report higher scores than the first two clusters. Finally, the fourth cluster, which consists of married military personnel, shows the highest scores in both resilience and emotional intelligence.
Regarding the third specific objective, the results found in the linear regression analyses suggest that resilience predicts the level of emotional intelligence in military personnel, confirming this fourth and final research hypothesis. These results align with previous research, which also indicates that resilience mediates perceived stress [
19] and life satisfaction [
21].
All of the above highlights the importance of resilience and emotional intelligence in the military context, especially considering the professional trajectory that requires confronting multiple challenges. Therefore, designing intervention programs focused on resilient and emotional skills in the military appears to be an effective measure to assist military personnel in dealing with the challenges they face in their professional careers. This would promote the development of personal resilience to successfully cope with adverse situations and enhance their personal and collective well-being [
59,
60].
This study has significant implications for professional practice, emphasizing the strong relationship between resilience and emotional intelligence, which points towards improving the quality of life for military personnel, enhancing their ability to cope with adversities, and improving emotional stability. This, in turn, strengthens their well-being and professional competence by fostering proactive behaviors, which benefits the achievement of previously established institutional objectives. These findings are likely to contribute to the design of future intervention programs aimed at promoting resilience and emotional intelligence among military personnel.
Among the limitations of this study, it is important to note that the sample evaluated is specific and limited to one type of profession within the military field. The results may not be generalizable to other branches of the military, such as the Navy or Air Force, or to other professions. Furthermore, since this is a cross-sectional design, these findings should be corroborated in studies with longitudinal designs that allow for the establishment of cause-and-effect relationships between the studied variables.
For future research directions, a deeper study of the relationship between resilience and emotional intelligence in this context would be beneficial. Consequently, it would be interesting to implement intervention programs that consider the variables analyzed in this study, allowing for pre-posttest comparisons to draw solid conclusions. Moreover, given the relevance of stress in the development of resilience and emotional intelligence, future studies should include this variable, as well as other variables that promote the proper development of military personnel, to enhance these psychological traits and increase their personal well-being.
