Abstract

Context: Receiving a diagnosis of cancer can be devastating and life-altering news for any person. Recent studies have shown that spirituality and religiosity may have positive effects on physical and psychological well-being in patients with cancer. This review article aimed to assess the effects of spirituality and religiosity on well-being of patients with cancer.

Evidence Acquisition: A literature search was done for related articles published between 2000 and 2014 on PubMed, Science Direct, Embase, Web of Science, and Scopus for both English and non-English language articles by the following keywords: “cancer”, “spirituality”, “religion/religious/religiosity”, and “Well-being”.

Results: Of the 16 studies reviewed, ten studies have found that spirituality and religiosity were positively associated with well-being, two studies found no association, and four studies showed both beneficial and detrimental effects of spirituality and religiosity on well-being of patients with cancer.

Conclusions: Most of the reviewed articles showed the important role of religiosity and spirituality in palliative treatment of patients with cancer. It has recommended that medical care team, especially nurses, pay more attention to spiritual and religious beliefs of patients with cancer to improve their well-being.

1. Context

Cancer is one of the rapidly growing diseases that involves about 12 million people worldwide (1). It is reported that seven million patients die of cancer annually, and 25 million people are currently living with a diagnosis of cancer (2). In developed countries, cancer has become the leading cause of death, and in developing countries, it is second only to heart diseases (3). Based on World Health Organization (WHO) report, the increasing cancer burden affirms the urgent need for prevention and care (2, 4). Today, palliative care is considered as the key goal for patients living with cancer (5, 6). The WHO defines palliative care as an approach that improves the quality of life (QoL) of patients and their families facing life-threatening diseases by means of prevention or early identification and treatment of patients, which could be physical, psychosocial, or spiritual (7). This holistic approach recognized that the needs of dying patients were complex and multifaceted and, therefore, required going beyond a conventional biomedical understanding of the disease and its treatment (8). Based on literature, spirituality and religiosity are two essential subjects in palliative care that have attracted an increasing interest among patients with cancer in the context of health and healthcare practice (6, 9). The National Quality Forum (NQF) identifies spiritual and religious aspects of care as one of eight domains of quality palliative and hospice care in patients with cancer (10). Moreover, WHO definition of palliative care has cited that spiritual and religious aspects of care are essential to good palliative care among patients with cancer (7). According to the National Cancer Institute, spirituality is defined as “an individual’s sense of peace, purpose, and connection to others, and beliefs about the meaning of life” that may be expressed through religion or other means, while religiosity, one type of expression of spirituality, is defined as “a set of beliefs and practices associated with a particular religious tradition or denomination” (11). Today, the role of spirituality and religiosity in the adjustment to cancer has been studied in both qualitative (12-18) and quantitative (19-34) studies. It is recognized that the spirituality and religiosity as a holistic human characteristic can have a positive influence on improvement of patients’ QoL (9, 25, 26, 31, 34-36), functional well-being (37), and physical well-being (38) and reduce of distress symptoms (33, 38, 39) in patients with cancer. It is reported that between 50% and 95% of patients with cancer view religion and spirituality as personally important issues (40, 41). Patients with cancer report their spirituality helps them find hope, gratitude, and positivity in their cancer experience, and that their spirituality is a source of strength that helps them cope, find meaning in their lives, and make sense of the cancer experience as they recover from treatment (42). These two variables also serve multiple functions in long-term adjustment to cancer such as maintaining self-esteem, providing a sense of meaning and purpose, and giving emotional comfort (43). Despite the important role of religious and spiritual beliefs in the lives of patients with cancer, these two variables can also adversely affect patients with cancer’ health (44). Some investigations have found that spiritual and religious experiences and practices cause depression, poorer QoL, and callousness towards others if they saw the crisis as a punishment from God, if they feel excessive guilt, or if they had an absolute belief in prayer and cure and an inability to resolve their anger if cure did not occur (42, 45).

Due to the contradictory results of previous research regarding to the effect of spirituality and religiosity on well-being of people with cancer, and considering that most studies conducted in this regard are qualitative, we decided to review quantitative studies that assessed the effects of spirituality and religiosity on well-being of people with cancer.

2. Evidence Acquisition

In this review article, we performed an electronic search on articles published from August 1, 2000 through April 28, 2014, on PubMed, Science Direct, Embase, Web of Science, and Scopus for both English and non-English language articles, using the following keywords as medical subject heading (MeSH): “cancer”, “spirituality”, “religion/religious/religiosity”, and “Well-being”. The references of retrieved items were also searched to identify additional items about this topic. In addition, reference lists of journal papers were searched by hand for relevant papers. We included articles that examined the role of spirituality and religiosity in patients aged ≥ 18 years with a diagnosis of cancer within the last five years. We excluded studies that examined spirituality and religiosity in children with cancer, in relatives of patients with cancer, or in professionals and caregivers. Moreover, we excluded quantitative and review studies.

In total, we found 1032 items (including duplication). After careful reading of title, abstract, and full text (when available), 110 articles were initially selected, but after further reading, 40 studies that met the eligibility criteria were included. We excluded 24 of these 40 articles due to lack of patient history (14 articles), being quantitative and review studies (8 articles), being done in children (2 articles). Therefore, 16 studies were finally included in this review.

3. Results

Among 16 evaluated studies, 12 studies were cross-sectional (19-22, 24-26, 29, 31-34), three were longitudinal (23,27,28), and one was randomized clinical trial (RCT) (47) in design. Based on results, eight were conducted in the United States (20, 21, 24, 25, 27-29, 31), two in Canada (19, 32), two in Iran (34, 46), two in Taiwan (32, 33), one in Australia (22), and one in both Korea and the United States (26). Most patients were English speaking with a Christian or Jewish religion. Sample sizes of studies ranged from 32 to 198. Ages of the participants ranged from 19 to 84 years. Seven studies examined mixed cancer groups (20, 25, 26, 31). Of the 12 studies that examined specific types or sites of cancers, the majority examined breast cancer (19, 21, 23, 24, 27-29, 34). Of the 16 reviewed studies, ten studies (19, 22, 23, 26, 28, 29, 31, 33, 34, 46) have found that spirituality and religiosity were positively associated with well-being, two (21, 27) found no association, and four (20, 24, 25, 32) showed both beneficial and detrimental effects of spirituality and religiosity on well-being of patients with cancer (Table 1).

4. Conclusions

In this review, we have summarized studies that assessed the effects of spirituality and religiosity on wellbeing of patients with cancer. Although reviewed studies vary in terms of methodology, kinds of cancer, and objectives, results consistently show the importance of religiosity and spirituality in coping with a cancer diagnosis and subsequent treatment. Based on evidences, most review studies that investigated the effects of religiosity and spirituality in patients with cancer showed mixed results. Thune-Boyle et al. (47) reviewed 17 studies examining religious and spiritual cognitions and/or behaviors as coping strategies in adults dealing with cancer. They found only seven of 17 studies with some evidence for the beneficial effect of religious coping, but one of these also found religious coping to be detrimental in a sub-sample of their population. Three studies found religious coping to be harmful, and seven did not find significant results. In another review study that was conducted by Visser et al. the majority of the cross-sectional studies (31 of 36) found a positive association between spirituality and well-being and four studies with a longitudinal design showed mixed results (48). Moreover, a recent systematic review confirmed that spirituality and religiosity were associated with reduced mortality only in studies on healthy populations, but not in studies on diseased population (49). However, there are some review studies that indicated the association of religiosity and spirituality with better well-being in patients with cancer. In a review, Schreiber et al. (50) suggested that religion and/or spirituality can play a role in maintaining and/or increasing well-being among breast cancer survivors. Moreover, in an integrative review of the current literature, Tate provides support that spirituality is a meaningful part of the breast cancer experience for African-American women, and has important role for patients to overcome the physical, psychological, and emotional burdens that accompany a breast cancer diagnosis (51).

The discrepancy in the findings may result from using insensitive measures of religiosity and spirituality, relying on cross-sectional designs, or failing to incorporate cultural diversity in measures and designs. Today, various mechanisms are identified to be implicated in the relation between religiosity and spirituality and outcomes of cancer treatment. Results of recent studies have shown that cancer survivors have adjusted to their life-threatening illnesses by holding onto hope, compensating for losses, and actively maintaining their personal lives through a process of experiential learning. This learning process allowed individuals to create or discover opportunities that might lead to maintaining or gaining some enjoyment of life even as suffering continue during the course of their cancer and recovery (52, 53).

In addition, studies suggested that spirituality and religiosity with such mechanisms include behavioral, physical, social support, and psychologic buffering of the severity of cancer symptoms. Behavioral mechanisms include religious encouragement (i.e. the religion encourages the adoption of a set of behavioral practices) to engage in various health behaviors such as offering diet guidelines (e.g. diets low in fat or to avoid nicotine). Physiologic mechanisms include participating in religious practices (e.g. prayer and meditation) offering means of relaxation and thereby contributing to better health outcomes. Socialization is a key element of religious attendance and it increases with increased religious involvement. The benefits of social support are extensively documented in the health psychology literature; however, it also appears that religious and spiritual beliefs provide benefits in their own right because they facilitate increased intimacy and connection with others. Regarding psychological mechanisms, spirituality and religiosity are found to enhance psychologic well-being through lowering levels of depression, anxiety, and hopelessness, and consequently, indirectly affect physical health. Another mechanism is cognitive improvement that has not been extensively investigated as mediator in the association between religious coping and cancer treatment outcome (38, 54). Therefore, more research is needed in this area to better understand the specific factors, mechanisms, and pathways of action that mediate religiosity and spirituality in cancer treatment. Despite the beneficial effects of religiosity and spirituality on cancer, these patients are prone to spiritual distress upon facing with their diagnosis, change in disease stage, and the difficulties of ending their lives that may lead to poorer outcomes and is, therefore, considered maladaptive.

Today, the importance of spiritual and religious beliefs in patients with cancer was discussed from numerous perspectives in the nursing literature (55, 56). Florence Nightingale noted that spirituality is intrinsic to human nature and is our deepest and most potent resource for healing in patients with cancer (57). In a recent study conducted by Winkelman et al. on terminally ill patients with cancer, most patients (87%) agreed it was important for nurses to consider patients’ spiritual concerns within the medical setting (36). However, it is reported in many studies that religious and spiritual needs of advanced patients with cancer are not supported by nurses (9, 58, 59). Based on studies, 81% of patients with cancer reported that most nurses ignored their spiritual or religious beliefs (59), and 72% reported their spiritual needs were supported minimally or not at all by nurses (9). The main reason for this negligence may be the lack of healthcare professional training, design of clinical practices, shortages of healthcare providers, payment, and policy constraints. Therefore, to provide holistic nursing care, nurses must understand that spirituality and religiosity are important in most patients with cancer. It is recommended that nurses assess the role of spirituality and religiosity in patients with cancer and develop personalized plans of care as they accompany these patients throughout the cancer journey. Totally, spiritual and religious beliefs are not a static and often changes as the cancer experience unfolds. Therefore, close surveillance of patients is necessary to ensure that cues indicating spiritual and religious needs are not missed. Nurses also should nurture and support their own spirituality and religiosity to be available as a spiritual and religious resource for their clients.

Our study had some limitations that should be considered. First, many reviewed studies were cross-sectional in design that make it impossible to establish causality among spirituality, religiosity, and various physical and psychosocial symptoms. Second, the sample sizes of most reviewed articles were relatively small. Third, most studies used mixed cancer groups at different stages of their illness, which could affect their sense of well-being. Fourth, the majority of the studies in this review were conducted in the United States (8 of 16). According to the United States Central Intelligence Agency, 81% of Americans adhere to one of the three major religions (Christianity, Judaism, and Islam), which may differ considerably from other countries. Therefore, in order to fully understand the role of religiosity and spirituality in cancer treatment, future studies should examine these two factors as their main aim, using specific cancer groups that are similar in terms of length of illness. In addition, use of more longitudinal and randomized clinical trials and specific questionnaires are suggested. Furthermore, future studies should consider a systematic control for possible influential variables such as perceived social support.

The most reviewed articles show the importance role of religiosity and spirituality in palliative treatment of patients with cancer, thus, confirming the place of spirituality and religiosity in the holistic construct of palliative care among patients with cancer.
