The findings revealed that perceived social support was significantly associated with lower death anxiety and hopelessness. This aligns with Walbaum et al., who reported that death anxiety in advanced cancer patients relates to demographic factors including age, gender, and time since diagnosis (
1). Although not analyzed separately here, results suggest social support may moderate these factors' impact. Patients with stronger support networks experienced reduced hopelessness and anxiety, consistent with Soleimani et al. (
2) and Sharif Nia et al. (
17) in Iran. Soleimani et al.'s (
2) systematic review indicated death anxiety is typically moderate and associated with female gender, marital status, and disease progression. In Asian cultures, including Iran, religious and family contexts may either alleviate anxiety through spiritual frameworks or intensify dependency and hopelessness without genuine support. Similarly, Tan and Karabulutlu found higher social support reduced hopelessness and depression among Turkish cancer patients (
18).
The findings of this study are supported by extensive empirical evidence confirming the protective role of social support in mitigating negative psychological consequences among cancer patients. A meta-analysis by Li et al. of 52 studies identified a significant negative correlation between social support and death anxiety, emphasizing that social support enhances patients' quality of life and mental well-being (
19). Similarly, Pehlivan et al. reported that perceived family support was significantly associated with lower hopelessness among Turkish cancer patients (
13). Jimenez-Fonseca et al. found that social support, hope, and optimism significantly reduced anxiety and depression risks in 600 Spanish cancer patients, with high prevalence rates (49.8% anxiety, 36.6% depression) underscoring the urgent need for mental health attention (
20). In the Iranian context, Farahbakhsh et al. demonstrated that perceived social support reduced death anxiety and enhanced self-efficacy in women with breast cancer, accounting for 21% of self-efficacy variance (
21). Hadian et al. reported a significant negative relationship between social support and death anxiety in 160 women with breast cancer (
22). Nezami et al. found significantly higher death anxiety among women with breast and cervical cancers compared to gastrointestinal cancers, highlighting the psychological distress associated with female identity (
23). Dadashi et al. identified that sense of coherence, along with demographic factors, predicted 85% of death anxiety variance (
24). These findings underscore social support's vital role in psychosocial interventions across diverse cultural settings, including Iranian society.
Perceived social support strongly predicts hopelessness (41.1%) and death anxiety (32.6%) through several mechanisms. It fosters belonging and self-worth, helping patients retain existential meaning when facing cancer, especially in family-centered Iranian culture. Emotional and instrumental support enhance control and reduce isolation, buffering against negative thoughts. The greater effect on hopelessness suggests its stronger dependence on support, while death anxiety involves religious and experiential factors. These findings highlight the need for multidimensional interventions including family education, existential dialogue, and supportive environments and for integrating social support within culturally informed, longitudinal research and clinical assessments.
5.1. Conclusions
This study reveals that perceived social support plays a crucial role in reducing death anxiety and hopelessness among cancer patients. Consistent with prior research, the findings emphasize its importance for mental health and the need to integrate psychosocial care with medical treatment. Interventions aimed at strengthening family support, improving coping skills, fostering meaningful communication, and enhancing social interactions can improve patients’ quality of life. Integrating social support assessment into routine care, especially for younger and female patients, is vital to prevent severe psychological distress.
5.2. Limitations
The findings of this study should be interpreted considering several key limitations. First, the cross-sectional design precludes causal inferences between social support and psychological variables; longitudinal studies are required to establish the directionality of these relationships. Second, the study population was limited to hospitalized patients in the city of Kerman, restricting the generalizability of the results to other cancer patients in different regions of Iran or other cultural contexts. Replication in more diverse samples is therefore necessary. Third, the data were collected through patient self-reports, which may be subject to response bias, especially concerning sensitive variables such as death anxiety and hopelessness. Future research could provide a more comprehensive understanding of the dynamics of social support and psychological outcomes in cancer patients by employing longitudinal designs, incorporating cultural and religious dimensions, and investigating moderating or mediating roles of relevant variables.
