The findings of this study indicate that the participating adolescents had moderate spiritual well-being, with those without chronic diseases displaying significantly higher levels of spiritual health than their counterparts with chronic diseases. These results align with the findings of Taheri et al., who reported an average spiritual well-being score of 74.2 among adolescents with chronic diseases, and 84% of them had moderate spiritual health. Furthermore, this study found no statistically significant relationship between spiritual well-being and factors such as age, gender, and economic status (
20). Ahmadpoori and Motaghi also researched the spiritual health of adolescent students and found their spiritual well-being, including existential and religious health dimensions, to be at a moderate level, corroborating the findings of the current study (
18). The use of the same questionnaire across these studies facilitates the comparison of results.
The study by Rubin et al. found no difference in the spiritual well-being of adolescents with chronic diseases compared to healthy adolescents, which contrasts with the findings of the current study (
21). Leung et al. assessed the spiritual health of end-of-life cancer patients and found it to be high (
22). This may be attributed to the chronic nature of cancer, the different life cycles, and the progression of the disease.
Davis et al. observed that during the COVID-19 pandemic, there was little evidence of significant changes in individuals' mental and spiritual health outcomes. It suggests that pandemics like COVID-19 might not markedly affect the spiritual well-being of vulnerable populations, such as those with chronic illnesses, or might even mildly improve their attitudes and spiritual health (
23). This could be due to individuals with chronic illnesses already having adapted to challenging conditions, thereby diminishing the pandemic's impact on their spiritual response. This aligns with the current study's findings and other research indicating a relatively stable spiritual well-being in individuals following disasters (
24).
Contrary to some studies (
25,
26), the current study found that adolescents, both with and without chronic diseases, experienced low levels of COVID-related anxiety. This discrepancy could be due to the timing of the respective studies. Other research has shown adolescents to perceive high levels of COVID-related anxiety, stemming from direct exposure to the disease, school closures, and quarantine measures leading to restricted social interactions and heightened anxiety.
Lavigne-Cervan et al. reported on the effects of COVID-19 restrictions on anxiety, sleep, and performance among children and adolescents in Spain, revealing that 66.9% and 67.9% of adolescents scored moderate to high levels of anxiety, respectively (
27). This is in line with Jiao et al., who identified behavioral-emotional disorders among 320 adolescents aged 13 - 18 during the COVID-19 pandemic, noting common issues like attention problems, irritability, fear of discussing the coronavirus, and clinginess (
28). Similarly, a study by Cao et al. on university students in China at the onset of the pandemic found that 24.9% of students experienced moderate to severe levels of COVID-related anxiety, with social support inversely related to anxiety levels (P < 0.001), highlighting the importance of monitoring adolescents during COVID-19 to mitigate the risk of mental health issues (
29).
Contrarily, the study by Chen et al. found no significant relationship between anxiety and the COVID-19 pandemic, suggesting that the pandemic did not affect participants' anxiety levels. This conclusion diverges from the findings of the current study and others (
1). By examining other research (
26,
30) in line with the current study's results, it emerges that insufficient information about the new disease and inadequate knowledge regarding appropriate immunization methods tend to heighten anxiety levels. Conversely, increased awareness, participation, and adherence to health protocols among adolescents and their families can reduce anxiety following news related to COVID-19.
Moreover, adolescents without chronic diseases reported higher spiritual health scores and experienced less anxiety, a trend also observed among adolescents with chronic diseases, albeit to a lesser extent. In other words, adolescents with chronic diseases displayed lower spiritual health levels and experienced greater anxiety during the COVID-19 pandemic. A study in Portugal aiming to explore the impact of religious-spiritual compatibility on fear and COVID-related anxiety levels found that participants with higher scores on the spiritual well-being scale reported lower anxiety levels due to coronavirus (
31), echoing the findings of the present study. Supporting these results, Nodoushan et al. investigated the link between spiritual health and stress in pregnant women during the COVID-19 pandemic, discovering that spiritual well-being effectively reduces stress during the crisis, potentially influencing factors related to preterm delivery and unhealthy births (
32). However, Blumenthal et al. did not establish a significant connection between spiritual health and heart disease, anxiety, or stress (
33). The discrepancies among these findings could be attributed to cultural and religious differences across the study populations, individual beliefs, the type of spirituality enhancement programs, and the sample sizes (
34).
These studies suggest that in the face of the COVID-19 pandemic, spirituality could serve as a means to promote health, prevent disease spread, and effectively alleviate stress and COVID-related anxiety while fostering hope and tranquility, thereby enhancing immunity against the virus (
35,
36). Since spirituality is linked with life stability, wellness, harmony, and a sense of connection to oneself, the divine, society, and the environment, individuals with higher spiritual health levels tend to be more patient and capable of enduring and managing life's challenges. They view problems from different perspectives, which helps in better coordinating the body's internal mechanisms and reducing dysfunctional thoughts and anxiety compared to those with lower levels of spiritual health (
37).
The influence of spiritual well-being in life can serve as a mechanism for coping with anxiety induced by crises. Anxiety related to COVID-19 adversely affects all facets of health, quality of life, and individuals’ outlook on the future, while spiritual well-being can mitigate these adverse effects (
36). Studies have indicated that the widespread COVID-19 pandemic, the anticipation of adverse events affecting oneself and one's family, along with the stress and challenges brought about by the pandemic in the country, have negatively impacted adolescents' mental health, elevating their levels of COVID-related anxiety (
1). However, a higher sense of spiritual well-being has been associated with reduced levels of COVID-related anxiety among adolescents.
5.1. Limitations
Due to the widespread presence of the disease in Iran and the partial operation of schools during this research, opportunities for face-to-face sampling were limited. Moreover, the comparison samples differed significantly in terms of age and gender, with the group of patients with chronic diseases being significantly younger than the group without chronic diseases. The results of this research are correlational and do not establish causality.
5.2. Conclusions
The findings suggest a significant relationship between spiritual well-being and the level of COVID-related anxiety, showing that spirituality plays a beneficial role in reducing the anxiety provoked by COVID-19. Adolescents with high levels of spiritual well-being during this crisis experienced less COVID-related anxiety. It is thus vital for caregivers and policymakers to focus on enhancing spiritual health and offering planned spiritual care as part of comprehensive services to lessen adolescents' anxiety during this period.
