1. Introduction
The emergence in late 2019 and rapid spread throughout 2020 of the SARS-CoV-2 virus has led to an unprecedented public health crisis in the modern world [
1]. Despite the general availability of vaccines beginning in 2021, political, legislative, and societal factors contributed to pandemic fatigue and vaccine hesitancy during the second year of the pandemic [
2]. This led to a third wave in spring 2021 and a catastrophic fourth one beginning in October 2021 [
3]. with the period in between characterized by fluctuating restrictions, partial lockdown measures, and uncertainty. Since the pandemic’s early days, the indirect toll (e.g., through saturation of public health measures, lockdowns, or restrictions) has been signaled [
4,
5]. Prior pandemics have shown that actions undertaken to control the spread can precipitate mental health issues and reduce compliance down the line [
6]. Comparing suicide statistics around the 2003 SARS outbreak in Hong-Kong, these grew between 2002 and 2003, yet failed to return to pre-outbreak levels even after the outbreak ended [
7]. A pandemic’s psychological footprint can be more extensive than its medical one [
8]. Even after restrictions were lifted in China, most people continued to self-isolate to some degree [
9]. Despite the heterogeneity of distribution, an increase in loneliness compared to pre-pandemic times was described in a meta-analysis [
10].
While social isolation describes the
objective absence of social interactions [
11], loneliness, refers to the
subjective experience arising from the discrepancy between one’s desires and received social interactions [
12]. Though conceptually separate constructs, objective and perceived social isolation are interrelated, with the former a risk factor for the latter [
11,
13]. Even before the full brunt of the pandemic, loneliness has been described as an epidemic affecting developed countries [
14,
15]. It has been identified as a risk factor for somatic illness [
11,
16,
17], neurodegenerative symptoms [
18] and psychiatric disorders [
11,
13]. A comparative analysis of loneliness throughout Europe found that former Soviet Countries had an even higher incidence of loneliness than the rest of Europe in all age brackets [
19]. This is important because the pandemic came superimposed on prior risk factors [
20]. Compared to pre-pandemic times, some risk groups for loneliness remained the same (e.g., women living alone), other groups experienced greater risk (e.g., younger people), and groups previously safe became at risk (e.g., students) [
21].
Ainsworth and Bowlby’s attachment theory emerges as a variant of object relations theory, aimed at studying human development via the initial bonding between children and primary caregivers [
22]. ). Using the behavioral patterns Ainsworth described, Hazan and Shaver (1987) described three types of adult attachment: secure, avoidant, and anxious [
23]. Attachment styles have been linked to loneliness through social skills [
24,
25], with insecure attachment linked to worse social skills [
26]. Thus, attachment appears to predicate loneliness [
26,
27] with greater loneliness associated with insecure attachment styles [
23,
26,
28] and secure attachment predicting the lowest levels of perceived loneliness [
23,
29].
The attachment system reflects how individuals regulate their affect, especially in novel or threatening situations [
30]. Bowlby’s theory also stipulated that novel or threatening conditions, like a pandemic, automatically trigger the attachment system [
31]. Securely attached individuals will seek close partners for comfort and support, helping them cope with distress. Meanwhile, avoidantly attached individuals will try to minimize distress and retreat, while anxiously attached individuals cope by persistently signaling distress and seeking reassurance [
30]. During the Covid-19 pandemic, anxious attachment predicted more suicidal ideation and loneliness during a longitudinal study [
32]. Meanwhile, avoidant attachment was associated with loneliness, perceived stress [
33] and suicidal ideation [
32].
After primary and secondary appraisals of stressors, Lazarus in 1966 described the coping process [
34]. This process is fluid, with both threat appraisal and employed strategies undergoing multiple reappraisals [
35]. The efficiency of coping strategies can also depend on external factors: Park and colleagues pointed out that problem-focused coping substantially impacts positive mood in high-control situations, whereas emotion-focused strategies seem more suitable for uncontrollable stressors [
36]. Problem-focused coping, alternative seeking, and social support were commonly used during the prior epidemics [
37]. Studies measuring coping strategies employed during the Covid-19 pandemic have revealed mixed results, partially due to the different models employed. Thus, more distress was associated with passive coping [
38], self-blame, venting and disengagement [
39], wishful thinking [
40], and stronger problem-focused coping [
41,
42]. In line with Park’s suggestion, Fluharty and colleagues [
43] found that problem-focused, avoidant, and emotion-focused coping strategies were not associated with faster mental health improvements during the pandemic, while socially supported coping was associated with faster decrease in afective symptoms.
Taking it all together, our study focused on the general population of Romania between the third and fourth Covid-19 outbreaks and aimed to investigate: (i) attachment, coping, and their relationship to loneliness and emotional distress; (ii) loneliness as a mediator between attachment dimensions and emotional distress. Secondary goals included measuring the impact of gender and age.
3. Results
3.1. Gender Differences
Independent-sample t-tests were conducted to compare age, loneliness, emotional distress, avoidance, and coping styles between genders. Significant differences in the scores for problem-focused coping were found between male (M=8.06, SD=4.05) and female responders (M=10.23, SD=4.34), t(139)=-2.45, p = .014). Male participants also presented lower scores (M=33, SD=14.84) versus female participants (M = 41.08, SD = 14.31) on emotion-focused coping, t(139) = -2.60, p = .010. Avoidant coping presented significant gender differences between male (M = 22.50, SD = 9.21) and female participants (M=27.32, SD=10.61), t(139) = -2.29, p= .023. Finally, gender differences were also found for socially supported coping between males (M=15.50, SD=7.47) and females (M=19.43, SD = 9.94). Statistical analysis failed to reveal gender differences for age, loneliness, emotional distress, and attachment. Results are summarized in

3.2. Correlational Analyses
Pearson correlation coefficients were computed to assess the linear relationships between loneliness, emotional distress, attachment, and coping styles. Loneliness presented positive correlations with emotional distress (r(139) = .70, p <.001), attachment anxiety (r(139) = .63, p <.001) and avoidance (r(139) = .51, p <.001), along with problem-focused coping (r(139) = .21, p <.013) and socially supported coping (r(139) = .20, p <.016). Emotional distress presented positive correlations with attachment anxiety (r(139) = .53, p <.001) and attachment avoidance (r(139) = .41, p <.001), as well as problem-focused coping (r(139) = .24, p = .004) and socially supported coping (r(139) = .26, p = .002). Results are summarized in
Table 2.
3.3. Regression Analysis
Attachment as Predictor of Loneliness and emotional distress
Multiple linear regression analysis was used to test if attachment styles significantly predicted loneliness while also correcting for age. The results of the regression indicated that the two predictors explained 42.3% of the variance (R2 = .42, F(3, 137)=33.54, p < .001). Model coefficients (see
Table 3) indicated that attachment anxiety (b= 1.07, SE = .17, β = .50, t(137) = p < .001) and attachment avoidance (b = 3.83, SE= 1.55, β = .20, t(137) = 2.46, p =.015) predicted loneliness.
The model for emotional distress was also significant, explaining 30.9% of the variance (R2 = .30, F(3, 137) = 20.39, p < .001). Individual coefficients (see
Table 3) indicated that only attachment anxiety (b = .87, SE = .18, β = .42, t(137) = 4.72, p < .001) predicted emotional distress.
Coping styles as predictors of loneliness and emotional distress
We conducted a similar analysis using coping styles as the predictor of interest, once more controlling for age as a covariate. The overall model for depression was statistically significant, explaining 11.8% of the variance (R2 = .11, F(5, 135) = 3.64, p = .004). Individual coefficients revealed that problem-focused coping (b = 1.03, SE = .36, β = .33, t(135) = 2.79, p = .006), emotion-focused coping (b = -.34, SE = .14, β = -.38, t(135) = -2.42, p = .015) and socially supported coping (b = .39, SE = .16, β = .28, t(135) = 2.38, p = .019) predicted loneliness.
Our emotional distress model achieved statistical significance, predicting 18.8% of the variance (R2 = .18, F(5, 135) = 6.23, p < .001). Model coefficients revealed only problem-focused coping (b = .91, SE =, β = .30, t(135) = 2.67, p = .008), socially supported coping (b = .61, SE = .15, β = .45, t(135) = 3.93, p < .001) and age (b = -.31, SE = .10, β = -.24, t(135) = -3.01, p = .003) predicted emotional distress.
Model 1
The results of our mediation analysis indicated that attachment anxiety was a significant predictor of loneliness (B = 1.33, SE = .13, 95% CI[1.05,1.60], β = .63, p <.001) and loneliness was a significant predictor of emotional distress (B = .58, SE = .07, 95% CI[.44, .73], p<.001]. With the inclusion of loneliness as a mediator, attachment anxiety no longer significantly predicted emotional distress (B=.30, SE=.15, 95% CI[-.00,.61], p = .054), consistent with complete mediation. The predictors accounted for approximately 50.3% of the variance (R2 = .50).
The indirect effect was tested using a percentile bootstrap estimation approach using 10000 samples, implemented via the PROCESS macro (Hayes, 2017). These results indicated that the indirect coefficient was significant (B=.73, SE = .15, 95% CI[.49,1.09], standardized β = .38. Standardized coefficients are presented in
Figure 1.
Model 2
The results of our second mediation analysis revealed that attachment avoidance was a significant predictor of loneliness (B = .81, SE = .11, 95% CI[.58,.1.03], β = .51), and loneliness was again a significant predictor for emotional distress (B = .64, SE = .06, 95% CI[.50,.77], p < .001). Once loneliness was introduced as a mediator, attachment avoidance no longer significantly predicted emotional distress (B=1.22, SE=.10, 95% CI[-.08,.33], p = .25), consistent with complete mediation. Approximately 49.9% of the variance was accounted for by the two predictors (R2 = .49).
The bootstrapped results for indirect effect indicate that it achieved statistical significance (B = .51, SE = .11, 95% CI [.30,75], standardized β = .33. Standardized coefficients are presented in

4. Discussion
The Covid-19 pandemic, and the public health measures that accompanied it, came superimposed over what was already being described as a loneliness epidemic in developed countries [
15]. The persistence of socially isolating behavior and perceived isolation after the release of pandemic measures could be explained by a wide variety of factors, from learned helplessness, global and economic stressors [
54] to social withdrawal as a coping mechanism[
55]. The pandemic’s widespread psychological footprint is still being discussed, though some have already argued for the emergence of a Pandemic Disengagement Syndrome [
56]. The present study, undertaken during the second year of the pandemic in Romania, set out to measure the general population’s emotional distress and loneliness while accounting for predisposing factors like attachment, coping styles, and demographic variables like age and gender.
Demographic factors in our study revealed weak to statistically insignificant results. Correlational analysis showed that age presented statistically significant, albeit minimal-to-low strength negative correlations with emotional distress, attachment anxiety, problem-, emotion-focused, and avoidant coping. Our results align with prior research that named young adults at risk for more mental health symptoms during the pandemic [
57,
58,
59]. Age, however, was a significant predictor of emotional distress when considered alongside coping, but not attachment, suggesting the latter plays a more salient role in the resilience of older age groups during the pandemic. This aligns with Okely and colleagues’ [
60] suggestions that with age, more refined emotional and cognitive skills provide individuals with better ways of coping with the lockdown. One of the mechanisms Okely mentioned was emotional stability, which has been consistently linked to attachment theory [
61,
62], as our results indicate a small yet significant decrease in attachment anxiety with age. Adult attachment is not set in stone [
63,
64]). Parent-child bonds can predict attachment stability for the first fifteen years, yet said stability diminishes past that point [
65]. Our study found no significant differences between genders in our samples for emotional distress, loneliness, or attachment dimensions. Gender differences in attachment are still being debated [
66] and are subject to important cross-cultural factors [
67], and the similar scores for attachment dimensions reported by both men and women could account for the lack of group differences regarding loneliness, or emotional distress, contrary to most reports on women being as greater risk than men for both loneliness [
21] and mental health symptoms [
68,
69]. Our sample’s predominantly female, predominantly younger distribution could explain the minor effects and lack of statistical significance.
Consistent with previous studies, insecure attachment influences emotional distress [
33,
70,
71]. The attachment styles are closely tied to how an individual handles their affect, especially during novel and/or threatening conditions [
30] and are linked to both the sympathetic nervous system stress response [
72] and the hypothalamic-pituitary-adrenergic stress response [
72,
73], and partially depend on relationship context (Pietromonaco & Beck, 2019). Considering the restrictions imposed by social distancing, partner presence and relationship quality might have become a critical support pillar for some individuals. Moreover, attachment styles predict potentially protective or damaging behaviors arising in response to stressors [
74]. These secondary attachment strategies [
75,
76] vary according to attachment, with anxiously attached individuals displaying hyperactivating strategies and those avoidantly attached employing deactivating strategies. Predisposing, precipitating, and crisis-state factors can mediate the link between attachment insecurity and suicidality [
77]. Loneliness has been found to mediate the effect between insecure attachment and the medical lethality of suicide attempts [
78].
Individuals high in attachment anxiety perceive others to be emotionally unpredictable and unreliably responding to their affective needs, closely monitoring significant others for cues of emotional unavailability [
33,
79]. This hyperactivation strategy leads to further activation of the attachment system and inhibition of exploratory behavior [
33]. Our regression analysis showed that attachment anxiety and avoidance explained nearly half the variance in perceived social isolation, with the former displaying an effect twice as strong as the latter. Attachment anxiety also significantly predicted nearly one-third of emotional distress symptoms, though attachment avoidance failed to reach the significance threshold. Furthermore, our first mediation model revealed that attachment anxiety fully predicted emotional distress via loneliness, with the direct effect becoming insignificant once the mediator was introduced. Individuals that score high on attachment anxiety tend to use hyperactivating strategies that lead to increased perception and expression of threatening signals making them more prone to developing anxiety disorders [
80,
81], post-traumatic stress symptoms [
82,
83] and post-natal depression [
84].
Conversely, individuals high in attachment avoidance present a different attachment strategy: deactivation, inhibiting the attachment system, and minimizing perceived frustration and distress [
79]. Attachment avoidance presented a statistically significant predictor for loneliness in our regression analysis, albeit not as strong as attachment anxiety. Relationship quality is more related to avoidance rather than attachment anxiety [
85], with avoidant individuals experiencing their partners as less supportive [
86]. Considering the restrained social options during the pandemic, it would explain why those more avoidantly attached perceived themselves as lacking support and described themselves as lonely. Our regression analysis failed to find a significant effect for attachment avoidance of emotional distress once attachment anxiety was considered. However, our subsequent mediation model revealed a significant, fully mediated path from attachment avoidance to emotional distress via loneliness. Attachment avoidance has been linked with the risk of depression [
83] and suicide ideation [
62,
87]. Finally, since both attachment avoidance and anxiety presented essential effects on mental health, a synergistic effect cannot be disconfirmed. This is conceptually equivalent to This is conceptually equivalent to Bartholomew’s ‘fearful’ type [
88] which feature individuals with high attachment anxiety (model of self) and high avoidance (model of other) and is conceptually similar to the disorganized attachment style observed further described by Main and Solomon [
89]. Though disorganized attachment is less studied in adults [
90], it has been shown to be associated with high levels of attachment avoidance and anxiety [
91] and clinically associated with more severe personality traits [
92].
In contrast, correlation and regression analyses revealed more mixed, weaker interactions between coping, loneliness, and emotional distress. Notably, problem-focused and socially supported coping was associated with more loneliness and perceived emotional distress. Our results align with those of Fluharty and colleagues [
43], which found that participants with higher scores for problem-focused and socially supportive coping had higher mental health symptoms at the start of the pandemic lockdown in the UK. Socially supportive coping is known to be associated with better mental health and increased resilience[
93], as are problem-focused strategies [
94]. During the pandemic, coping strategies mediated the relationship between uncertainty and psychological distress [
95]. As the period between the third and fourth waves was marked by uncertainty and mixed messaging from the media and authorities, it is possible that outward-focused, reactive strategies like active coping and planning might have proved insufficient and detrimental for the individual. Similarly, socially supported coping, by depending on the presence of others, might have proven inefficient a strategy during a time marked by restrictions and reduced social opportunities. Meanwhile, emotion-focused coping seemed to have a negative predictive effect on loneliness alone but not on perceived emotional distress. Because loneliness is defined as the reduced perceived quality of social support, it would be reasonable to assume those that focused on addressing the emotions of the situation would have a better-perceived quality of social interactions with peers or partners. These results again reinforce Park’s [
36] suggestion that context is essential in determining the efficacy of coping strategies.
Our study is not without strengths or limitations. The dimensional approach and utilizing an attachment scale focused on romantic attachment strategies can be considered a fundamental strength of our study. To the best of our knowledge, aside from an ongoing study by Edjolo and colleagues [
96], this is the only pandemic-related study to measure attachment and coping styles in the same sample. Similarly, exploring loneliness in Romania, an at-risk country, is a developing field to which our research will hopefully contribute. Among the more important limitations, we mention our sample’s predominantly female and more educated distribution, which restricts its application to the general population. The cross-sectional design also severely restricts any causal inferences from being drawn. Finally, selection bias inherent in online questionnaires cannot be disconsidered.
Loneliness is not only a symptom of social isolation. Future research should consider the importance of dyadic relationships, the role of partners, or lack thereof, in emotion regulation, and how childhood attachment is pivotal between received and perceived support. Furthermore, coping strategies should not be automatically segregated into ‘adaptive’ or ‘dysfunctional,’ as the controllability of the context plays a crucial role in the efficacy of the strategies employed.
