Religious coping is differentially associated with physiological and subjective distress indicators: Comparing cortisol and self- report patterns Alison M. Haney1, Sean P. Lane2 1Department of Community Health and Health Behavior, School of Public Health and Health Professions, University at Buffalo, The State University of New York 2Department of Psychological Sciences, University of Missouri Abstract Use of religious coping in response to life stress is associated with improved mental and physical health outcomes. The aim of this study was to examine the influence of religious coping on conscious self-reported and non-conscious physiological stress responses to an acute, real-world stressor to better understand how this benefit may be conferred. This study examined the trajectory of subjective distress and cortisol patterns leading up to and following a stressful college exam using daily diary and ambulatory saliva samples, respectively (N students = 246). Religious coping was not significantly associated with subjective reports of distress. However, prior to the exam, greater use of religious coping was associated with an ostensibly more adaptive accelerated return to a cortisol baseline. This protective effect was no longer significant when the exam was over, suggesting that religious coping acts as a protective buffer against physiological stress responses rather than aiding in subjective recovery from stress. Keywords Coping; Daily Diary; Religion; Salivary Cortisol; Stress Introduction Involvement in religion is associated with enhanced positive psychological states, stress- buffering, and protection against negative psychological states.1 Turning to religion as a form of distress tolerance is an adaptive strategy that may support overall well-being and buffer against maladaptive behaviors and mental health difficulties.2 Several mechanisms have been proposed to explain how religiosity may improve mental and physical health outcomes, including social support through involvement in a religious community, use of positive religious coping (e.g., turning to the divine for help) to manage distress, Corresponding author: Correspondence concerning the article should be addressed to Alison M.

Religion, as a buffer against psychological stress, has also been found to impact physiological indicators of stress, such as heart rate, blood pressure, and cortisol levels.1 In a sample of individuals with HIV/AIDS, higher levels of religiosity, and a sense of peace from religion, and faith in God, specifically, was associated with lower levels of urinary cortisol and lower levels of psychological distress and mental health problems.7 The association between religiosity and long-term survival in this sample was mediated by optimism, altruistic behaviors, and cortisol concentration.7 In addition to overall chronic and/or stable levels of cortisol, religiosity may be associated with more acute adaptive daily diurnal cortisol reactive changes. In a sample of women with fibromyalgia, a disorder marked by endocrine and psychological stress, those with higher reported intrinsic religiosity (e.g., internal thoughts of a personal connection to the divine) and non-organizational religiosity (e.g., private prayer) had steeper diurnal cortisol slopes, while those with lower reported religiosity showed a more flattened slope.8 Here, steeper slopes are considered to indicate a quicker return to homeostatic baseline, signifying more functional stress regulation.9 This pattern remained after statistically adjusting for social support. However, levels of intrinsic and non-organizational religiosity were not associated with a reduction in self-reported perceived stress. Religious affiliation has been found to predict this steeper diurnal cortisol slope 10 years later, even when adjusting for general emotional coping and social support.10 Participation in specific religious activities also has been found to be associated with diurnal cortisol patterns consistent with adaptive regulation. One ethnographic study of indigenous Sahariya refugees in central India found that over a nine-day period of group religious rituals, the magnitude of difference between morning and evening cortisol levels increased, reflecting a more adaptive peak-deviation cortisol arousal response.11 This corresponded with increased subjective psychological well-being on group ritual days, particularly among those with higher levels of economic insecurity, suggesting that religious affiliation may buffer against other stressors that have documented stress-impairing consequences.11 Research on the connection between religion and cortisol has largely focused on chronic stressors such as illness, though there has been some examination of more acute stressors that impact individuals for a short duration but then may have both short- and long-term consequences, such as public speaking. For acute stress, the connection between religion and cortisol levels has been examined in the context of laboratory-based stress-induction tasks. One study found that low to moderate levels of baseline/pre-stress cortisol levels were associated with greater church attendance.12 However, religious participation was not associated with the trajectory of cortisol during the stress task when estimated alongside baseline cortisol and demographic variables in a regression model (none of the model variables reached statistical significance). The stress task used in this study (the Trier Social Stress Test) is designed to increase cortisol levels then return them to baseline over approximately 75 minutes. These results suggest that cortisol levels taken during an Haney and Lane Page 2 Behav Med. Author manuscript; available in PMC 2025 October 01. A uthor M anuscript A uthor M anuscript A uthor M anuscript A uthor M anuscript acute stress task may not be significantly related to religious participation when considered alongside baseline cortisol and other demographic variables. In another study with a laboratory stress task, religious participation (as measured by frequency of service attendance) alone did not predict cortisol responses.13 However, those with higher levels of religiously-motivated forgiveness and frequency of prayer showed significantly lower cortisol responses to the stress-inducing task.13 This suggests that dimensions other than frequency of service attendance, such as intrinsic religiosity, may be more strongly related to cortisol responses to acute stressors. The impact of religious coping on time-bound stressors that may exert influence over the course of a day or several weeks is still unclear. This study seeks to examine the role of religious coping when dealing with short-term, real-life stressors. Specifically, the influence of religious coping is examined before and after a stressful, time-limited event, with stress measured both by a physiological indicator and a subjective indicator. Notably, the impact of the stressoris assessed over the course of continuous days, which examines a different timescale of both cortisol and self-report response profiles than the reviewed experimental paradigms that operate on the order of minutes to hours. By using this design, it is possible to determine whether religious coping differentially influences reactions to a non-chronic life stressor and begin to elucidate a possible physiological contribution of religiosity to ecologically valid subjective and physical well-being over time. Methods Participants Participants were college students preparing for premedical midterm science examinations. Informed consent was obtained from each participant, and all procedures were approved by the New York University and Columbia University Institutional Review Boards. A total of 246 individuals were initially recruited to participate in a two-week diary study (see Table 1 for demographic information). The study included three components: a background questionnaire, diary reports, and cortisol assessments. Two hundred and thirty- four individuals completed the background questionnaire, which contained demographic information, psychological functioning, coping style, and personality measures. The daily diary portion consisted of morning and evening reports of mood, health, and interpersonal functioning. We restrict our analyses to the 228 participants who completed at least one diary. In addition to the diary protocol, an a priori random subset of participants (N = 81) were invited to also provide multiple saliva samples per day to estimate diurnal cortisol levels. In the daily diary study, participants were primarily women (70.1%), with an average age of 20.1 years, and most identified their ethnicity as Asian (44.1%) or White (42.0%). The most commonly reported religious affiliations were Catholic (21.2%) and Protestant (16.0%), with 38.1% of the sample reporting that they did not belong to any religion. The cortisol subsample demographics were not significantly different than the whole sample in terms of demographics or other variables of interest. Haney and Lane Page 3 Behav Med.

A uthor M anuscript A uthor M anuscript A uthor M anuscript A uthor M anuscript Daily Diary Procedure Participants were randomly assigned to start the diary survey between 8 and 2 days before the selected midterm exam that they reported being the most stressful, only if they were enrolled in more than one qualifying premedical course. Regardless of the day participants started, each person completed a morning and an evening diary for at least 14 consecutive days, such that participants who started the daily diaries 2 days before the exam completed diaries until 11 days after the exam, and those that started 8 days before the exam completed diaries until 5 days after the exam. Morning diary surveys were completed online via an emailed web link using a smart phone or personal computer at the time the participant awoke, and evening diaries were completed via the same method before the participant went to bed. For additional details, refer to work by Shrout and colleagues.14 Cortisol Procedure As part of an independent nested experimental study design, participants provided saliva samples for either, 1) 5 consecutive days before the exam and 5 consecutive days following the exam, starting 2 days after the exam day, or 2) 2 consecutive days before and after the exam with a gap of 5 days in between, starting either 5, 4, 3, or 2 days before the exam. Participants provided 4 samples per day: upon waking, 30-min post-waking, before lunch, and before bedtime. Saliva was obtained using salivette collection devices and cotton swabs (Sarstedt, Numbrecht, Germany). Participants received written instructions and color-coded and numbered salivettes and completed a written log at each collection time providing information about the exact time of the collection, sleeping patterns, eating behaviors, medication, caffeine, and alcohol use, and other adjustment variables (e.g., chewing gum or brushing teeth). Saliva samples were stored in individuals’ home refrigerators until they were returned to the principal investigators to store at −20°C until all samples were collected and shipped for processing. Upon completion of the saliva sampling procedure, the salivettes were shipped to the MIDUS Biological Core at the University of Wisconsin, where they were stored at −60°C. For analysis, salivettes were thawed and centrifuged at 3000 rpm for 5 min, yielding a clear fluid with low viscosity. Cortisol concentrations were quantified with a commercially available luminescence immunoassay (IBL, Hamburg, Germany), with intra-assay and inter- assay coefficient of variations below 5%.15 A random subset of 10% of all saliva samples were double-assayed to estimate measurement reliability, which was r = .99. While a number of factors can influence cortisol levels, in healthy adults, cortisol levels are typically 10–27 μg/dL in the morning after waking and 2–4 μg/dL in the evening.16 Measures Religious Coping—Religious coping was assessed at baseline using the “turning to religion” items on the COPE, an inventory of coping strategies.17 These items (e.g., “I seek God’s help”) were rated on a 4-point Likert scale from 0 (“I usually don’t do this at all”) to 3 (“I usually do this a lot”). To reduce participant burden, only two items that were consistently the highest loading in the original study and replications were administered. In this sample, the mean for the religious coping subscale was 0.76 (SD = 1.07). The Haney and Lane Page 4 Behav Med. Author manuscript; available in PMC 2025 October 01. A uthor M anuscript A uthor M anuscript A uthor M anuscript A uthor M anuscript correlation between the two religious coping items on the COPE was r = 0.91 (pacross days (morning Rc = 0.80, evening Rc = 0.82). Analytic Plan Multilevel modeling (MLM) was used to examine the influence of religious coping on daily measures of cortisol and subjective distress, using SAS PROC MIXED (v9.4; SAS Institute).21 Our sample size was selected so that effect sizes of d = .23 would be 82% powered. In our first model with cortisol as the outcome, we utilized a 3-level model (moments nested within days, days within participants), as there were 4 collection times per day and 4/10 days of data collection per participant. In this 3-level model, cortisol estimates would be interpreted as the level of cortisol at a given time on a given day for a given individual. The model for cortisol included a time-coded variable to represent the morning cortisol response (“Peak”), data collection time adjusted for deviations in initial time at waking (“Time”), and collection time squared (“Time2”). Religious coping, the interaction of religious coping and cortisol peak, and the interaction of religious coping and time (and with time2) were included to determine the impact of religious coping on cortisol trajectories over the course of the day. Covariates included gender (0 = man, 1 = woman), a dichotomous religion variable (0 = not religious, 1 = religious), and several cortisol-relevant variables to adjust for confounding influences (medication use, overall health, hours of sleep, consumption of sour food, chewing gum, brushing teeth, and time Haney and Lane Page 5 Behav Med. Author manuscript; available in PMC 2025 October 01. A uthor M anuscript A uthor M anuscript A uthor M anuscript A uthor M anuscript of awakening; consistent with work by Stawski and colleagues).22 In order to examine differences between the pre- and post-exam period, interactions were included between each variable in the model and dichotomous variables representing whether a given measurement occasion was before (“pre”) or after the exam (“post”). Random intercepts for person and day were also included in the model. Random slopes were included for peak, time, time2, pre-, and post-exam to account for expected non-random variation by measurement time due to person-specific diurnal cortisol patterns. Subjective distress was modeled using a 2-level mixed-effects design, with moments nested within participants. Therefore, subjective distress estimates are interpreted as the level of subjective distress at a given measurement occasion for a given individual. The model predicting subjective distress included the number of days before or after the exam (−8 to 11; “Day”), whether the diary was completed on a weekday or weekend (0 = weekday, 1 = weekend; “Weekend”), whether it was completed in the morning or the evening (1= morning, 0 = evening; “Time of Day”), and the same gender and dichotomous religion variables used in the cortisol model. The predictor of interest was religious coping, and interactions between religious coping and day, and religious coping and time of day were also included. As in the cortisol model, each variable was simultaneously estimated by pre- and post-exam. Finally, the model included a random intercept for person, along with random slopes for day, time of day, pre-, and post-exam. Results Cortisol Table 2 presents fixed-effect estimates from the model predicting cortisol levels before and after the exam. Cortisol assessments displayed the well-established within-person/day pattern of acute elevation following waking (b = 4.54, t(76) = 5.99, pwas due to differences between individuals. At post-exam, the variance due to individual differences was 57.4%. This shift is the reverse of what was observed in pre- versus post-exam cortisol response variability, which may inform the veridicality, or at least the multidimensionality, of stress experiences as they are operationalized in psychological research. Discussion These findings indicate that the impact of religious coping on well-being varies both as a function of particular indicator (cortisol vs. subjective distress), and as a function of stress context. In this study, religious coping was associated with cortisol levels, in a Haney and Lane Page 7 Behav Med. Author manuscript; available in PMC 2025 October 01. A uthor M anuscript A uthor M anuscript A uthor M anuscript A uthor M anuscript suggestively adaptive way, only during a period of acute stress, in the days leading up to an important exam; but it was not predictive of cortisol after the exam, when individuals would be recovering from a stressful period. While this might suggest that religious coping is not associated with cortisol levels outside of a stressful period, extant literature does not necessarily bear this out. Instead, these findings may indicate that religious coping is not a significant predictor of stress recovery from a time-limited stressor but rather pre-emptive stress-buffering, consistent with decades of theory but little direct evidence until now.23 The way that religion was associated with cortisol during the pre-exam period offers some insight into the nature of this association. Those who reported higher levels of religious coping also had higher overall cortisol levels (though they did not have higher daily peaks). Individuals often increase their use of religious coping in response to life stress, and prior research on cortisol and coping has similarly found that using more coping techniques than typical is associated with increased cortisol levels.3,24 It is important to note that simply identifying as religious was not associated with cortisol during this exam stress phase, suggesting that using religious coping is unique from religious affiliation more generally in predicting cortisol. Importantly, religious coping seems to be used effectively to manage cortisol, as those who endorsed higher levels of religious coping also had overall steeper declines and faster asymptotes in cortisol levels over the course of the day than those with lower levels of religious coping, regardless of mean cortisol level. While religious coping was significantly associated with the physical stress response of individuals as they were approaching a significant stressor versus when they were recovering from it, religious coping was not associated with changes or differential trajectories in subjective reports of distress. These findings align with other literature identifying differences between physiological and subjective stress correlates of religious coping.8,13 These results are also consistent with literature indicating that religion may primarily act as a buffer against negative mental health outcomes (e.g., depression), rather than improving general mental functioning and well-being.25,26 There are several limitations to the current study, including that only one dimension of religious coping was captured. These data did not capture negative religious coping, a form of religious coping that involves feelings of persecution and abandonment. While religious individuals may differ in whether they use negative religious coping concurrently with positive religious coping, extant research suggests the two forms of coping may interact in clinically meaningful ways.27 Future work should include multidimensional measures of religious faith in order to determine what aspects of religiosity may most influence these stress-relevant processes. Additionally, there may be some unique properties of performance-based stress that are being captured in this study. While there was variability between subjects in their reports of religious coping and cortisol levels, on average this sample endorsed using religious coping only occasionally and had cortisol levels within a healthy range.16 The average level of stress reported by the sample was relatively low, and it is possible that these associations may differ during higher-stress events. This sample was primarily composed of young, mostly white students, and those who identified as religious primarily identified as Catholic or Protestant. This limits our ability Haney and Lane Page 8 Behav Med. Author manuscript; available in PMC 2025 October 01. A uthor M anuscript A uthor M anuscript A uthor M anuscript A uthor M anuscript to generalize these findings to other sociocultural groups or religious traditions. Importantly, this study lacked adequate power to examine group-level differences in religious affiliation and ethnicity, which are two highly interwoven factors known to contribute to the association between religion and health.28 Further, more representative research is necessary in order to comprehensively map the manifold of associations linking religiosity and health outcomes, especially given disparities in healthcare access that have robust epidemiological correlations with ideological markers. The initial patterns identified in this study warrant additional consideration, as these factors may influence the degree to which religion reduces cortisol levels. Conclusions The current study uniquely examines the impact of religious coping on a real-life acute, not chronic, stressor. These findings suggest that even when an individual does not perceive changes in their mental state, religious coping is still significantly associated with and may play a regulatory role in reducing cortisol levels. Of clinical relevance, this protective influence may buffer against future mental and physical health problems, and healthcare providers may consider inquiring about positive religious coping as part of their overall stress assessment of an individual. Researchers seeking to understand how religion influences health should consider measuring both self-reported and relevant physiological indicators, as our findings demonstrate the potential for distinct patterns. Clarifying the association identified in this study may improve our understanding of how religion influences long-term physical and mental health outcomes.
