   Introduction Top


Pharmacy education has been identified as one among the health disciplines that may promote academic stress in students because of its exhaustive nature of study.[1],[2]Stress negatively affects the mental health of the students resulting in stress-related disorders, low subjective life satisfaction, and poor academic performance.[3],[4],[5],[6] According to the World Health Organization, stress would become a major cause of mortality by 2020.[7],[8]

Pharmacy training is a rigorous and strenuous endeavor, which takes place in a competitive vocational environment. This includes taught lectures, clerkships, and residency in health-care settings that predispose undergraduate students to high levels of stress.[9],[10],[11] Stress screening has been considered in pharmacy students by some accreditation bodies.[12] Studies also report a high prevalence of self-medication of antidepressants to treat stress-resultant depression and anxiety among undergraduate pharmacy students.[13],[14]

There is a plethora of evidence regarding the determinants of stress in university students, which include academic-related matters, environmental factors, and personal events.[5],[15]Academia-related stress is most frequently reported.[3] It is most commonly reported in undergraduates especially in pharmacy students.[16],[17],[18] Several coping strategies have been suggested, however, none provides satisfactory solution.[19],[20]

The role of religiosity in physical and mental health is well established.[21],[22]Previous studies conducted by Al Rasheed et al.,[7] Al-Shagawi et al.,[8] and Albusalih et al.,[23] reported high academic stress and stress-related self-medication practice in pharmacy students of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. This study evaluated the impact of religiosity on subjective life satisfaction and academic stress in pharmacy students enrolled in this university.


   Materials and Methods Top


A descriptive study was conducted in December 2017 (1 month) to evaluate the impact of religiosity on subjective life satisfaction and perceived academic stress in pharmacy students.

Subjects and site

Pharmacy students studying in 2nd–5th year of Doctor of Pharmacy (PharmD) degree program, at Imam Abdulrahman Bin Faisal University located in Dammam, Saudi Arabia, were included in the study. Students enrolled in preparatory year (1st year) and those in their 6th year of study were not included. Students in 1st year are considered as prospective students and study a variety of allied health courses. They do not come under the jurisdiction of a pharmacy college. Students of 6th year of study are pharmacy residents and are stationed in hospitals. Students who did not wish to participate were left out.

Sampling strategy and sample size calculation

Convenient sampling strategy was used. The total number of pharmacy students enrolled at the time of study (December 2017) was 322. The sample size was calculated by an online sample size calculator using this figure, with the margin of error at 5%, and confidence level of 95%. The recommended sample size obtained was 175. A total of 242 respondents participated in the study.

Study questionnaires

The study used the following questionnaires separately as sections: the Duke University Religion Index (DUREL)[24] to assess the religiosity, Subjective Happiness Scale[25] for the assessment of subjective happiness of life, and Perceived Stress Scale (PSS) for documenting perceived stress because of academic load.[26]

Section one included questions related to demographic characteristics such as age, marital status, gender, year of study, smoking status, any diagnosed physical or mental disorder, monthly family income status, grade point average (GPA), and academic expectations, whereas second section incorporated DUREL that contained five items related to religiosity. Subjective Happiness Scale formed section three of the questionnaire and it contained four items related to subjective happiness of life. PSS was included in section four that contained 10 questions regarding perceived stress. Items related to religiosity included questions on frequency of engagement in organized and unorganized religious activities. Items related to subjective happiness investigated the degree of happiness in relation to various life events, and items related to PSS measured students’ perceived stress because of personal, academic, and social factors. All tools measured students’ response on a numeric rating scale. All psychometric tools used, that is, DUREL, Subjective Happiness Scale, and PSS were previously validated.

Data analysis

Data were analyzed through IBM Statistical Package for Social Services (SPSS) statistics for Windows, version 22 (IBM, Armonk, NY). Chi-square (χ2) test, Fisher’s exact test, and Pearson correlation were used as required. A value of P less than 0.05 was considered significant. The continuous variable was expressed as mean (X) and standard deviation (SD), categorical variables were expressed in sample count (N) and percentage (%), and the associations between variables were expressed in χ2 values and P value. The correlation results were interpreted in terms of correlation coefficient (ρ) and P value. Analysis of logistic regression was expressed as odds ratio (OR), probability (%), and relative risk (RR).

Ethics review and consent

The students were briefed about the study. A verbal consent was sought before handing the questionnaire. The study was exempted from review.


   Results Top


Of the total 322 pharmacy students, 242 responded to the survey. The response rate was 75.2%. Most of them were female students (n = 147, 60.7%) with a male:female (M/F) ratio of 1.55. The mean age of students was 20.76 years (SD, 1.3). The study incorporated responses from students studying in 2nd–5th year of PharmD. More than 90% of the students did not smoke and had no physical or mental illness. The mean GPA obtained from students was 4.3 of 5. A quarter of students (n = 57, 23.6%) highlighted that they find it difficult to live on monthly family income. The demographic information is tabulated in [Table 1].

The mean score for intrinsic religiosity (IR) was 12.9 (SD, 2.5), for subjective happiness was 17.5 (SD, 3.8), and for PSS was 19.8 (SD, 5.0). Organized religious activity (ORA) was positively correlated with IR; however, a statistically significant (P < 0.02) negative correlation existed between ORA and PSS. The correlation coefficient was moderate (–0.154). Non-organized religious activity (NORA) had a significant (P < 0.01) and a moderate positive correlation with IR (+0.172) and subjective happiness (+0.182). IR was positively correlated (+0.241) with subjective happiness with statistical significance (P < 0.01). The same was negatively correlated with PSS (–0.137) with statistical significance (P < 0.05). PSS was negatively correlated with subjective happiness (–0.369) with a P value less than 0.01. The correlation is tabulated in [Table 2].

[Figure 1] denotes relationship between PSS and ORA. A downward trend was observed in PSS as ORA score increased. Similarly, in [Figure 2], an inclining trend was observed between subjective happiness score and IR. The subjective happiness score increased with an increase in IR score. [Figure 3] reported a downward trend between subjective happiness and PSS. Subjective happiness decreased as PSS increased among respondents. The dotted lines represent mean value, whereas black line is correlation coefficient. The red circles are individual scores.

The association between gender and academic expectations was significant (P = 0.041) with χ2 value reported at 9.82. The association between gender and PSS score was significant (P = 0.017) with χ2 value reported at 8.129. No cell had expected count less than five, therefore the results are reliable. Moreover, the strength was weak to moderate, that is, phi reported at 0.184. Furthermore, association between expectation and socioeconomic status of students was significant (P = 0.0001) with χ2 value reported at 23.117 with moderate to strong effect, that is, phi value = 0.368. A significant association (P = 0.0162) was also reported between PSS score and physical and mental health profile of students with χ2 value reported at 9.566 and moderate effect, that is, phi reported at 0.209. The association of PSS score with socioeconomic status and health profile with academic expectations was not statistically significant (P < 0.05). The cross tabulation is presented in [Table 3].

The probability of perceiving academic stress for female students as compared to male students was 83.6% (OR, 5.1). The RR for female students having a high perceived stress was reported at 4.5. Similarly, probability of perceiving academic stress for students who have any physical or mental disorder was reported at 80.6% (OR, 4.16) with a RR of 3.257 for being in high stress. The OR and risk estimates are tabulated in [Table 4].

   Discussion Top


Studies have reported high levels of stress in students studying health-related subjects.[27],[28]It affects their happiness, quality of life, and academic performance.[29],[30]Their stress perception and response, coping strategies, and resistance, require an in-depth insight. This may help in devising new strategies and improving the existing approaches.[31] We found that religious activity or religiosity showed a positive effect on life satisfaction and academic stress reduction in pharmacy students.

Happiness is a term used for positive subjective experiences.[25],[32],[33]It consists of three components: experiencing positive emotion, being engaged in life activities, and finding a sense of purpose or meaning.[34] In general, it is a combination of positive emotions and meaningfulness. These attributes contribute to student learning process.

Stress is a complex concept and falls into three categories: stimulus, response, and interaction.[35] It occurs when straining exceeds an individual’s adaptive capacity. It may be caused by life transitions of adolescence, the requirements of a new program, the demands of higher education, and college life in young adults.[36] Evidence suggests that those who struggle with adjustment to college life are at risk for depression, anxiety, physical health problems, and negative health behavior.[37],[38],[39]

DUREL contains the first question about ORA, the second about NORA, and the final three regarding IR.[25] Our study showed a statistically significant positive correlation of NORA and IR with subjective happiness. But ORA failed to show such relationship with the same. This could be interpreted as: NORA and IR may reduce anxiety and increase subjective happiness in pharmacy students.[40] NORA and IR are concerned with personal religious coping or use of own cognitive and behavioral techniques in the face of stressful life events.[41] A successful management of problems in life is the basis of subjective happiness. Studies have proved this relationship in several domains.[42]

A negative correlation of ORA, NORA, and IR was observed with perceived stress in our students. This negative correlation is statistically significant in case of ORA only. This is because religious event may be considered as a social activity, and a research indicated that social relationship is one of the most important contributors to stress reduction.[43] Therefore, ORA had the most significant effect on stress reduction in our sample. This finding is also in line with previous studies.[44],[45]Religion may promote happiness and reduce stress as it gives people a sense of purpose and serves as a resource for coping with negative life experiences and existential fears.

Apart from religiosity, cross tabulation reported statistically significant association between academic expectation and stress in female students. A study published by Hamaideh[46] in 2012 reported that female students had a higher perception of stress, conflicts, and emotional reactions to stressors; however, male students had higher behavioral and cognitive reaction. Levesque and Roger[47] in 2011 reported gender inequality in academic expectation and stress. However, it was independent to religion.[48]

Our study suggests that religion may be considered as life satisfaction–enhancing and stress-relieving tool. This concept is also supported by several studies conducted in undergraduate students.[49],[50],[51] An intervention based on this concept may be possible because of high interest of students in spirituality.[52] Psychology of religion reveals that religious coping styles are conceptually distinct from nonreligious coping styles and uniquely influence psychosocial health above and beyond the effects of nonreligious coping.[53]

Our results also negate the findings of few studies that showed adverse effect of religiosity on life satisfaction and contributed to high stress in students.[52],[53],[54] However, factors that differentiated those studies with ours were the age group of the students, mixed religious affiliations as well as cultural and societal influences. Therefore, our findings apply to this population and may not be exhaustive.


   Conclusion Top


Religious activity was observed to have a positive effect in enhancing life satisfaction and reducing stress in pharmacy students in our study and may prove helpful in improving academic performance.
