Abstract

Background and Objective. Anxiety is an emotional and behavioral disorder that may disturb the student’s quality of learning and its outcome. This study is aimed at assessing the prevalence and associated factors among pharmacy students at a university in Saudi Arabia. Methods. We used a cross-sectional design, and data collection was carried out over a period of two months from September 2018 to November 2018 using paper-based self-administered questionnaires. The General Anxiety Disorder-7 (GAD-7) scale was used to measure and classify anxiety among the study participants. Results. The prevalence of anxiety among pharmacy students was 49% (83 students); 44 students (25.9%) had mild anxiety, while 24 (14.1%) students had moderate anxiety, and 15 (8.8%) severe anxiety. There were statistically significant differences in anxiety scores according to faculty type () and nutritional status (). Conclusion. The findings of this study revealed that half of the pharmacy students suffered from anxiety incidence during their studies at the university. However, the majority of them are experiencing mild to moderate. This may have a significant impact on academic performance and necessitates special attention.

1. Introduction

In the context of education and learning, healthcare students can experience high levels of stress in their everyday activities due to a variety of factors such as study burden, high amount of content to be learned in relatively short periods, and continuous exams and tests [1, 2]. This continuous stress can lead to anxiety, nervousness, and worry associated with the arousal of the nervous system [14]. Anxiety is a psychological condition as well as an emotional and behavioral disorder characterized by extreme worrying, a sense of fear, agitation, excessively sensitive responses, and deleterious thinking [5, 6]. It was evidenced that anxiety may decrease student’s academic interest, due to its physiological symptoms which include sweaty palms, cold hands and feet, panic attacks, fast breathing, racing heartbeat, and upset stomach [3].

Previous studies from different countries and discipline revealed that anxiety and its associated symptoms greatly influence students’ academic performance [710]. Moreover, several studies reported that most students (75%) during their under graduation and postgraduations at universities and colleges experienced some degree of anxiety symptoms [6, 11]. A large number of studies revealed the association between higher levels of anxiety and poorer academic performance among students [9, 10, 12]. Moreover, earlier data also showed that increased levels of anxiety were associated with decreased memory, loss of concentration, and cognitive decline [13].

Numerous studies reported that the prevalence of anxiety was found to be higher in students compared to the general public [1418]. The most common form of reported anxiety among the general community was specific phobias with a prevalence rate of 13.2%, followed by social anxiety disorder (5.8%) and generalized anxiety disorder (GAD) (5.1%) [19]. However, the most common prevalent form of anxiety among students was social phobia with 11.9%, showing an early age of onset while panic disorder and GAD had somewhat later onset [20, 21]. Another recent systematic review evaluated the prevalence of depression and anxiety and reported that an estimated prevalence of anxiety was 35% among college students [14]. With regard to Saudi Arabia, recent data indicated that the prevalence of anxiety among graduate and undergraduate medical students was 31.8%; however, the prevalence was higher in first year students compared to those in other years [4]. Another study conducted among undergraduate students in the south region of Saudi Arabia reported a prevalence of 47.2% for mild anxiety, 42.3% for moderate, and 10.5% for severe anxiety [22]. Similarly, a study conducted in the central region of Saudi Arabia with a multiethnic sample of medical students from Al Faisal University reported a high prevalence of 63% of anxiety. To the best of our knowledge, there is scarce data about the prevalence of anxiety among Saudi pharmacy students. Therefore, we aimed this study to assess the prevalence and socioeconomic correlates of anxiety among pharmacy students at Saudi University, Riyadh Saudi Arabia.

2. Materials and Methods

2.1. Study Design and Participants

The study population consisted of students in the second, third, and fourth year of the Doctor of Pharmacy (PharmD) program and bachelor courses (Bpharm) from King Saud University College of Pharmacy Saudi Arabia. The study excluded junior students, as many of them are not aware of some medical terminology used in the generalized anxiety disorder GAD-7 questionnaire. This was a descriptive cross-sectional study using paper-based questionnaires. Students were randomly invited to participate in the study. We contacted students in their free time before lectures, invited them to participate, and provided them with a summary of the study aims. We started data collection in September 2018 and completed it in the same semester. For the students in each academic year, we picked an exam-free time to gather the data. All participants signed an informed consent form before proceeding for the research.

2.2. Study Questionnaire

A structured questionnaire to collect the data for this study was developed according to an extensive review of the study in this field [23]. The questionnaire from the previous study [23] was collected and then redesigned and validated by senior researchers. After validation, a pilot study was initially conducted among senior staff with the help of a researcher at the university school of pharmacy after explaining the study details. Based on the results, the questionnaire was used with some minor modifications. This questionnaire measured pharmacy students’ anxiety and was adapted from the GAD-7 [23]. The first section of the questionnaire consisted of demographics and other participant characteristics, including gender, age group, year of study, sleeping habits, source of food, and smoking habits; the second part of the questionnaire included seven items on anxiety parameters (i.e., “Over the last 2 weeks, how often have you been bothered by the following anxiety problems?”) based on the GAD-7.

2.3. Prevalence Rate Calculations

The anxiety diagnostic questions were formulated according to the GAD-7, developed by UK clinicians and based on research evidence as well as the UK and European guidelines. The instrument classifies anxiety into three primary types: mild (score of 5-9), moderate (score of 10-14), and severe (>15) anxiety. The GAD-7 score was calculated by assigning scores of 0, 1, 2, and 3, to the response categories of “not at all,” “several days,” “more than half the days,” and “nearly every day,” respectively, and then adding together the scores for the seven questions. Total scores of 5, 10, and 15 were taken as the cutoff points for mild, moderate, and severe anxiety, respectively. When this scale is used as a screening tool, further evaluation is recommended when the score is 10 or greater.

2.4. Data Analysis

Manual data entry was carried out from each completed questionnaire received from participants. Data did not include any personal information of respondents such as name or address. A unique identifier associated with the survey questionnaire was used to identify individual responses and analyze the data. The students were informed that their participation was part of a study and voluntary.

Descriptive statistics included frequency counts and percentages and were calculated for each anxiety item. Statistical analyses were performed using SPSS version 25. Mann-Whitney and Kruskal-Wallis tests were applied to explore the association between participant characteristics and anxiety items with a significance level of 0.05. This study was approved by the Research Committee of College of Medicine, King Saud University, Saudi Arabia.

3. Results

3.1. Participant Characteristics

A total of 170 male pharmacy students from the second, third, and fourth year of bachelor and PharmD programs completed the survey. The majority of the participants (, 76.5%) were aged 21-25 years, and about 23% () were aged 18-20. One-quarter of the students (, 22%) were enrolled in bachelor’s degree programs, while the majority (, 77.6%) were completing the PharmD program (Table 1).

Most of the students were Saudis (, 96%). Of the 170 students who completed the questionnaire, 81 (47.6%) were second year, and 89 (52.3%) were third and 25 (14.7%) fourth year students. Less than a quarter of the students (, 23.5%) were overweight, and 9.4% () were obese. With regard to lifestyle habits, only 17.6% () smoked; 45.3% () ate homemade food, and 40.6% () restaurant food. A detailed description of participant characteristics is provided in Table 1.

3.2. Prevalence of Anxiety

The prevalence of anxiety among the study participants was 49% (): 44 students (25.9%) had mild anxiety, 24 (14.1%) had moderate anxiety, and 15 (8.8%) had severe anxiety (Figure 1).

3.3. Anxiety Parameters

Regarding the symptoms of anxiety, a detailed description of the frequencies of responses to anxiety parameters over the previous 2 weeks is given in Table 2.

As seen in Table 3, there were no differences in total anxiety scores between PharmD () and bachelor students () (); smokers () and nonsmokers () (); between those sleeping less than 6 h/day (), 6-8 h/day (), and 8-10 h/day () (); or those in the second (), third (), and fourth year () ().

4. Discussion

This study identified the incidence of anxiety among pharmacy students from a Saudi university. The total prevalence of anxiety was found to be 49%. A large number of previous studies from different countries utilizing diverse study populations, including both medical and pharmacy students, have investigated the prevalence of anxiety [2, 4, 22, 24]. The prevalence of anxiety in this study was found to be higher in comparison with other studies; for example, a recent study by Ibrahim and Abdelreheem using a sample of () both medical and pharmaceutical students from Alexandria University reported 29.3% of the prevalence [24]. Similarly, another study from Saudi Arabia estimated the prevalence of anxiety and depression among medical and nonmedical students () using a cross-sectional design and reported a prevalence of 14% among medical students and 23% among nonmedical students [25]. Another study by Bayram and Bilgel in 2008 among Turkish university students () found 47.1% of anxiety [26]. Consistently, another study by Shamsuddin et al. among Malaysian students reported 34% of anxiety [27]. Our study findings were lower than a previous study by Yusoff et al. among medical students () who reported a high prevalence of anxiety of 64.3% [28], although previous findings suggested that a high prevalence of anxiety (7.7% to 65.5%) among undergraduates were reported in American and European students [29]. However, the prevalence of anxiety may differ among gender, age group, educational year, and academic curriculum [4, 22, 24]. This might be the reason for the high prevalence of anxiety in this current study.

According to previous reports, students from various disciplines such as pharmacy and allied healthcare professions are more likely to be affected by high stress levels related to educational strategies, which results in different levels of consequences in students’ academic and social life [2225]. On the whole, variation in anxiety is expected and can be attributed to the difference in the used study tool and risk factors of anxiety, among which lifestyle (including smoking and student residential status) are critical players.

Recently, there have been important changes in the education curriculum, including the grading system and curriculum [30]. The academic grade will have a great impact on students’ ranking system, which will in turn reveal students’ status of education and knowledge, affecting their careers [31]. This might be the main factor contributing to the high levels of anxiety and other stress-related problems among students. A number of previous studies found that the prevalence of anxiety was associated with lifestyle factors of students which includes student social status [3133]. However, two other studies have revealed that females and smokers are more likely to report anxiety [19, 32] in comparison to males and nonsmokers. Additionally, earlier studies also reported that smoking is strongly associated with mental health [31, 33, 34]. On the other hand, it has been reported that increased episodes of anxiety and stress were principal factors leading to an increased smoking prevalence [35, 36]. Moreover, some studies found an association between anxiety and living status, with those living alone reporting more anxiety [31]. However, our study results revealed no significant differences in students’ anxiety according to demographic characteristics. Additionally, our results reported significant differences in anxiety according to the course of the study and nutritional status.

Anxiety is regarded as an important factor for students of any discipline, but particularly healthcare, that may negatively influence students’ life, both academic and personal. The present results indicated that pharmacy students suffered from some form of anxiety, ranging from mild to severe, reporting that they often felt nervous and were afraid that something awful might happen. Earlier literature on the management of anxiety advised that offering immediate treatment is beneficial to prevent serious consequences [37]. In fact, it was reported that anxiety contributes to depression, which in turn may lead individuals to entertain suicidal thoughts [36, 38, 39]. Furthermore, student counseling is widely used in developed countries such as the USA and the UK to cope with the students’ mental and emotional disorders [40]. The British Association for Counseling & Psychotherapy (BACP) has reported the importance of student counseling for achieving advanced knowledge in their curriculum [41]. In Saudi Arabia, previous reports suggested that a student counseling programme was not well recognized like in the USA and the UK. Although studies also reported that public and private universities in Saudi Arabia do have student counselors, but counselors may sometimes lack sufficient or adequate professional qualifications, or lack of adequate experience or understaffed to deal with the students [40, 42]. Undoubtedly, this is a serious issue not only for students but also for society, and further studies are needed to answer these questions.

Our study has several potential limitations. First, it included only second, third, and fourth year pharmacy students; secondly, this study was carried out in a single university in Saudi Arabia; the results may not completely reflect the anxiety of all pharmacy students. The generalizability of our findings should thus be evaluated in future studies. Additionally, we recommend the importance of assessment of anxiety and other behavioral and mental illness using noninvasive tools like questionnaires. This type of assessment may help the policymakers to assess the problems of society timely and make necessary recommendations.

5. Conclusion

The findings of this study revealed that half of the pharmacy students suffered from anxiety during their studies at university, with the majority of them experiencing mild to moderate. In addition, our study found no significant differences in anxiety according to participant characteristics. The high burden of studying along with repeated exams are likely to be the major reasons for anxiety. Students’ psychological problems such as anxiety, if recognized in early stages, can be treated with behavioral therapy, emotional support, and social skills training. This may help future graduates to overcome their difficulties and lead a healthier life. The present study results highlight the need for further research including larger groups of students in different fields.
