Internet Addiction Disorder and Its Pathogenicity to Psychological Distress and Depression among University Students: A Cross-Sectional Pilot Study in Bangladesh

Abstract

Worldwide Internet addiction is a newly emerging mental health and social issue among the youths causing neurological complications, psychological disturbances and social problems. Internet addicts make the Internet urgency more vital than family, friends and work. Several studies exposed that anxiety, backache, blurred vision, dry eyes, headache, sleep disturbance, depression, poor academic performance etc. are results of Internet addiction. Therefore, the objective of this study was to determine the Internet addiction as well as its psychological distress and depression among university undergraduate students of Bangladesh. The study was conducted among 475 students selected from five universities of Bangladesh from July 2015 to September 2015. The selected universities were Southeast University, University of South Asia, Primeasia University, Northern University Bangladesh and State University of Bangladesh. Each willing participants were subject of this study and they shared their opinion. The Young’s Internet Addiction Test (IAT), the General Health Questionnaire (GHQ-12) and Beck Depression Inventory (BDI-2) were used to determine Internet addiction, psychological distress and depression respectively. Results revealed that the university students showed varying degrees of Internet addiction, psychological distress and depression with respect to sex, age, year of study and residential status. The data revealed that 47.7% (127) male and 44.5% (93) female students showed severe Internet addiction followed by 27.1% (72) male and 33.9% (71) female students showed moderate Internet addiction, while 20.7% (55) male and 7.7% (16) female students had mild Internet addiction. The linkage between Internet addiction and sex was significant at P < 0.001. Furthermore, 29.7% (79) male and 32.5% (68) female students had psychological distress. Severe psychological depression was reported among 44.7% (119) male and 41.6% (87) female students. Equally year of study and residential status showed significant (P < 0.001; P < 0.05, P < 0.001) differences in Internet addiction and psychological depression. This study observed that university undergraduate students are at very close to the danger of Internet addiction and its pathological impact on psychological distress and depression. Therefore, the new generation is at great risk. However, without Internet scientific thinking is not possible. So only the rational use of the Internet can be fruitful in the long run.

1. Introduction

Internet Addiction Disorder (IAD) is the extreme use of Internet that interferes with existence (Block, 2008) . It is a multidimensional compulsive cognitive and behavior symptoms that completely dominates the addict’s life (Pies, 2009) . IAD is often comorbid with psychological disorders such as attention deficit hyperactivity disorder (ADHD) and depression (Kratzer & Hegerl, 2008) . Several studies show that within the first six months of using the Internet about 25% of users achieve Internet addiction criteria (Anonymous, 2016a) . Worldwide the prevalence of IAD is 6% in which Middle East accounts for 10.9%, North America accounts for 8%, Asia accounts for 7.1%, South and East Europe accounts for 6.1%, Oceania accounts for 4.3%, North and West Europe accounts for 2.6% (Ryan, 2014; Woollaston, 2014) . The variation of the prevalence of IAD may be because of the variation of assessment questionnaires, diagnostic criteria as well as selective use of participants. A study in the UK has been reported that the prevalence rates of the IAD as high as 18%, whereas very low incidence, 0.8% has reported in the Italy (Poli & Agrimi, 2012; Niemz, Griffiths, & Banyard, 2006) . According to the review of Weinstein and Lejoyeux the incidence rates of IAD in the United States and Europe have shown fluctuating between 1.5% and 8.2% (Weinstein & Lejoyeux, 2010; Young & de Abreu, 2011) . Another review of more than 100 studies in China showed that over 12% of male and 5% of female students disclosed signs of Internet addiction (Wallace, 2014) .

The causes of Internet addiction are not well known, but there are some known causes of Internet addiction that can vary by sex, age and personality. Social networking is one of the most common causes of Internet addiction (Kuss & Griffiths, 2011) . An Internet addicted person sometime feels web life just like a real one and develops highly emotional connections to online friends or even online dates. Online relationship via social network is another main source of Internet addiction (Leung & Lee, 2012; Griffiths, 2013) . A study has been reported that certain people may be predisposed to online addictions as like as one can be predisposed to an alcohol addiction (Echeburua & de Corral, 2010) . In fact, like drug addiction in Internet addiction, an analogous situation exists. The Internet similar to drugs in other addicted persons offers the euphoria feeling and addicts become reliant on this cyberspace in order to control the high feeling to normal. In addition to this when an Internet addict feels dazed, stressed, depressed and anxious, they use the Internet to search for comfort. Studies showed that people who are suffering from depression are more likely to develop Internet addiction (Ha et al., 2007; Young & Rogers, 1998; Kim et al., 2006; Lee et al., 2001) . Several studies suggest the presence of genetic predisposition to addictive behaviors (Eisen et al., 1998; Grant, Brewer, & Potenza, 2006) . As per to this concept genetic predisposition among people is due to lack of adequate number of dopamine receptors or have an insufficient amount of serotonin/dopamine, as a result they experience normal level of pleasure in events in which most people would find rewarding (Beard, 2005) . In order to increase the level of pleasure these types of individuals are more disposed to search for such type of behaviors like Internet that make them reward, but simultaneously placing them at higher risk for addiction (Cash et al., 2012) . The CIAR (Center for Internet Addiction Recovery) stated that Internet addicts suffer from emotional problems, including depression and anxiety- associated disorders and frequently use the fabulous world of the Internet to psychologically escape unpleasant feelings or stressful situations (Young, 2009; Anonymous, 2016b) . In addition to this Internet addicts are also addicted to drugs, alcohol, tobacco, sex, chronic overeating etc. (Morris, 2009; Ho et al., 2014) . Many scientists and researchers have claimed that the uncontrollable Internet users can generate morphological mutations in the structure of the brain. A study in Chinese college students exposed that use of computer for about 10 hrs a day and for 6 days a week, showed decreases in the dimensions of the dorsolateral prefrontal cortex, rostral anterior cingulate cortex, supplementary motor area and parts of the cerebellum compared to control students (Yuan et al., 2011) . It has been hypothesized that these variations reveal learning-type cognitive optimizations for using computers more competently, but correspondingly diminished temporary memory and decision-making capabilities as well as increase the pleasure to remain online rather than the actual world (Mosher, 2011) . Many researchers and clinicians have marked that a diversity of psychological disorders occurs together with IAD. There is controversy about which came first, the addiction or the co-occurring disorders (Ryan, 2014; Kratzer & Hegerl, 2008) . A previous study showed that depression, anxiety, hostility, interpersonal sensitivity and psychoticism were consequences of IAD (Ryan, 2014) .

Researchers observed that most Internet users are young people, especially university undergraduates (Jones, 2002) . Previous study exposed that Internet user is higher in younger than adult and mainly 19 to 24 years of age group are considered as a high risk group for Internet addiction (Koo & Kwon, 2014) . Another study exposed that university students are more at risk of becoming Internet addicts due to more free time, lack of monitoring on account of being away from parents and sometimes efforts to become away from arduous university routines (Soule, Shell, & Kleen, 2003; Young & Rogers, 1998; Kandell, 1998) . As well as this Internet addiction is more predominant on university campuses because of laptops and computer labs are within easy proximity.

In Bangladesh the use of computer began in the 1960s and assumed widespread in the nineties (Zaman & Rowshon, 2011) . Like many developed and developing countries, the Internet in Bangladesh has perceived remarkable growth. However, only 0.1% of the population used the Internet in 2000 and it rises to 31.9% in 2015 (Anonymous, 2016b) .

Previously, there was no study that showed the prevalence of IAD and its association with psychological problems in Bangladeshi students. Therefore the objective of this study was to analyze Internet addiction disorder and its co-relation with psychological distress and depression among undergraduate university students in Bangladesh.

2. Materials and Methods

2.1. Study Site

The study was conducted on undergraduate students selected from five universities of Dhaka, Bangladesh which were Southeast University, University of South Asia, Primeasia University, Northern University Bangladesh and State University of Bangladesh.

2.2. Study Design and Data Collection

This was a student based, cross-sectional study conducted among students selected from five universities in Dhaka, Bangladesh. The study was conducted between July 2015 to September 2015 and throughout this period a total of 475 students were selected. Information about sex, age, year of study, residential status and study relevant information were collected that is listed in Table 1.

2.3. Internet Addiction Test

In this study modified version of the Young’s Internet addiction test was used (Young, 1998) . It was a 20 item test with six point range from 0 to 5. The response options were; 0 indicated did not apply, 1 indicate rarely, 2 indicated occasionally, 3 indicated frequently, 4 indicated often and 5 indicated always. The obtainable scores ranged from 0 to 100 in which higher total scores indicated excessive Internet uses. Scores ranging from 0 to 30 indicated normal Internet use, 31 to 49 indicated mild Internet addiction, 50 to 79 indicated moderate Internet addiction and scores ranging from 80 to 100 indicated severe Internet addiction (Young, 1998) .

2.4. General Health Questionnaire

Goldberg DP et al., introduced the General Health Questionnaire (GHQ) for the determination of the presence or absence of psychological distress among respondents (Goldberg et al., 1978) . General health questionnaire, ver- sions-12 (GHQ-12) was used in this study. It contains 12 questions in which six of which are positively phrased

Table 1. List of collected information.

and six negatively phrased. Each item was rated on a four point scale includes; less than usual, no more than usual, rather more than usual, or much more than usual. The binary scoring method (0-0-1-1) was used for this study whereby the two least symptomatic answers scored 0 and the two most symptomatic answers scored 1. So the obtainable scores ranged from 0 to 12 in which a score of 1 and above indicates a greater degree of psychological distress (Goldberg et al., 1978) .

2.5. Beck Depression Inventory

Beck Depression Inventory, second edition (BDI-2) developed by Beck et al., was used for the determination of depression and its severity among respondents (Beck, Steer, & Brown, 1996) . It contains 21 questions, each answer being scored on a scale value of 0 to 3. The obtainable scores ranged from 0 to 63 in which higher total scores indicated more severe depressive symptoms. Scores ranging from 0 to 13 indicated minimal depression, 14 to 19 indicated mild depression, 20 to 28 indicated moderate depression and scores ranging from 29 to 63 indicated severe depression (Beck, Steer, & Brown, 1996) .

2.6. Statistical Analysis

Data were collected and the results were finally compiled and presented. Chi-square tests of goodness of fit was performed to find relationships between variables. SPSS 15.0 (Chicago, IL, USA) and Microsoft Excel 2010 (Roselle, IL, USA) was used for the statistical and graphical evaluations. The results were considered as statistically significant at P < 0.05.

2.7. Scope for Error

Since the study was based on the answers provided by the students and their prescriptions, so there was no scope for error unless they provided misinformation.

2.8. Ethical Considerations

The study protocol was approved by the ethics committee of the Department of Pharmacy, Southeast University, Dhaka, Bangladesh. The study was conducted in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki.

3. Results

Among 475 students, 56% (266) were male and 44% (209) were female. The age group of the 41.5% (197) students were 18 - 21 years, followed by 58.5% (278) in the age group between 22 - 25 years. The students were in various years of study ranging from first to fourth (i.e., final) years; in which 26.7% (127) were in 1st year, 22.7% (108) were in 2nd year, 22.5% (107) were in 3rd year and 28% (133) were in 4th year student. The majority of the students, 71.2% (338) lived without family. Detailed participant related information is given in Table 2.

Table 2. Socio-demographic profile of the students.

The outcomes of Internet addiction test is shown in Table 3 with respect to sex in which 20.7% (55) male and 7.7% (16) female students were affected by mild Internet addition. 27.1% (72) male and 33.9% (71) female students were moderately addicted by Internet and severe addiction was seen among 47.7% (127) male and 44.5% (93) female students. The association between Internet addiction and sex was significant at P < 0.001. In the age group 18 - 21 years, 36.5% (72) students were affected by severe addiction and 41% (114) in the age between 22 - 25 years. From 1st year students, 37% (47) had severe addiction and among 2nd year students, severe addiction was realized for 34.3% (37) students. In case of 3rd year students, 47.7% (51) possessed severe addiction, but for 4th year students severe addiction was reported for 51.1% (68) students. The relationship between Internet addiction and year of the study was significant at P < 0.001. Among students who lived with family 26.3% (36) had severe addiction. For students who lived without family, 30.2% (102) were moderately addicted and severe addiction was shown for 47.9% (162) students. The link between Internet addiction and residential status was significant at P < 0.001.

The results of psychological distress are given in Table 4. Psychological distress was reported among 29.7% (79) male and 32.5% (68) female students and remaining 70.3% (187) male and 67.5% (141) female students did not possess any distress. In the age group 18 - 21 years, 28.4% (56) had psychological distress and for age group 22 - 25 years, 83% (29.9) had psychological distress. Among 1st year students, 24.4% (31) had psychological distress followed by 35.2% (38) in 2nd year, afterward 25.2% (27) in 3rd year and 34.6% (46) in 4th year. Psychological distress was reported for 29.9% (41) students who lived with family and 37.9% (128) students who lived without family.

In the age group 18 - 21 years, 36% (71) had moderate depression and in the age group 22 - 25 years, severe depression was reported for 39.2% (109) students. 40.2% (51) 1st year students were affected by severe depression after that 38.9% (42) in 2nd year, followed by 40.2% (43) in 3rd year and 55.6% (74) in 4th year students. The relationship between psychological depression and year of study was significant at P < 0.05. According to residential status, students who lived without family, 46% (63) had moderate depression and in case of students who lived without family, moderate depression was reported for 26.9% (91) and 52.9% (179) had severe depression. The bond between psychological depression and sex was significant at P < 0.001.

4. Discussion

The Internet is making the world smaller by making information more accessible to all and creating connections with different people around the world (Howe, 2016) . However, it has also attracted many people to spend more time on the Internet, so that it becomes the center of their lives and causing neurological difficulties, psychological disorders and social complications (Griffiths, 2005; Shaffer et al., 2004) . The younger generation is more prone to Internet addiction as a means of communicating, learning and seeking new challenges (Gordon, Juang, & Syed, 2007) . This is the first study showing prevalence of Internet addiction and its correlation with psychological distress and depression among undergraduate university students in Bangladesh.

The socio-demographic profile of the students shows that the prevalence of Internet addiction and its pathogenicity to psychological distress and depression was greater in male that female students. In addition to this 22 - 25 years aged students who lived without family in 4th year of study had greater Internet addiction as well as psychological distress and depression among 475 students of this study.

The prevalence of Internet addiction, psychological distress and depression varied among the students. In this study out of 475 students, 47.7% male and 44.5% female students were in the range of severe Internet addiction, then 27.1% male and 33.9% female students were in the range of moderate addiction, whereas 20.7% male and 7.7% female students were in the range of mild addiction. Young to adult every age people use the Internet, especially university students use the Internet for the preparation of the assignment, presentation, intern paper, reports etc. As well as to obtain current information the role of the Internet is unavoidable. However, the Internet assists university students in their academic endeavors, but it may also decrease the academic performance of students in fact, it is very easy for them to get addicted to the Internet (Greenhow, Robelia, & Hughes, 2009; Katz, 2010) . Due to excessive use of some site on the Internet these include web surfing, social media, pornography, freelancing, dating and video games that has been reported to be characterized by anxiety, agitation, headache, backache, weight gain or loss, blurred vision, dry eyes, sleep disturbance, depression, poor academic

performance, carpal tunnel syndrome etc. (Wetterneck et al., 2012; Wise, Kim, & Kim, 2010; Baird, 2010) . Furthermore, 29.7% (79) male and 32.5% (68) female students were found to be psychologically distressed. Severe psychological depression was reported among 44.7% (119) male and 41.6% (87) female students. This form of finding was in line with previous reports which have predicted many psychological problems arising from Internet addiction by university students (Weiser, 2000) . Gnisci et al., stated that male college students were more addicted to the Internet than the female students (Gnisci et al., 2011) .

The age of the students in this study ranged from 18 - 25 years. Severe Internet addiction 41% (114) was reported in the age group 22 - 25 years, whereas moderate addiction was 34.5% (96) and mild addiction was 10.4% (29). In the age group 18 - 21 years, 36.5% (72), 28.9% (57) and 16.2% (32) students had severe, moderate and mild addiction respectively. Like Internet addiction, psychological distress was also maximum, 29.9% (83) in the age group 22 - 25 years. Stress is highly connected with depression. It is well known that depression appears after a stressful event (Monroe & Reid, 2010) . In this study severe psychological depression of this aforementioned aged (22 - 25 years) group was 39.2% (109) and moderate depression was reported for 31.3% (87) students whereas mild depression was reported for only 16.5% (46) students. A previous study revealed high levels of Internet addiction and psychological distress in young adolescents than adult adolescents (Okwaraji et al., 2015a) .

From 1st to 4th year students severe Internet addiction was reported among 4th year students than remaining year students, which was 51.1% (68) consequently psychological stress was 34.6% (46) and severe depression was 55.6% (74). This is may be as a result of preparing them for final year examinations and this may make them stay more on the Internet in the process of searching for study materials to help them write up their assignments as well as prepare very well for their job life. During this period they may tend to become addicted to the Internet more than other undergraduates who are not in their final years (Okwaraji et al., 2015b) . Moderate Internet addiction was reported among 2nd year students, which was 40.7% (44) than 1st and 3rd year students. Addition to Internet lead to psychological problems in this study greater number of 2nd year students, 35.2% (38) had psychological distress than 1st and 3rd year students. This is not astonishing because young students are more at risk of becoming addicted to the Internet than older students due to the availability of free time, lack of monitoring by parents or caregivers and as a way of getting away from tough university routines. Okwaraji et al., showed that final year university undergraduates were at higher risk of developing Internet addiction and depression (Ozgul et al., 2013; Shaw & Gant, 2002) .

Regarding the residential status significant difference was noticed for Internet addiction, psychological distress and depression among students. In this study, 26.3% (36) students lived with family were severely Internet addicted, then 29.9% (41) had psychological distress and 26.3% (36) had severe psychological depression. On the other hand, students who lived without family had more addicting behavioral than students lived with family. In this study, 47.9% (162) students lived without family had severe Internet addiction, but 37.9% (128) had psychological distress and 52.9% (179) had severe depression. Family plays an important role in the growth of student life (Christensen, 2013) . The finding of this study suggests that Internet addiction and its psychological effect among students lived without family are probably due to lack of family bonding or lack of family care, aloneness and adjusting them with virtual life (Young, 2004) .

5. Conclusion

The study exposed that the more addicted the students are to the Internet the more they develop psychological distress and depression. This is an alarming statistic that needs to be addressed as soon as possible. By considering the current fact of Internet addiction and psychological problems among undergraduate students as noticed in this study, there is prerequisite for parents and caregivers to monitor the Internet use and activity of the students. For students who are gradually addicted to the Internet or already addicted to the Internet, there is compulsory to screen them for proper counseling; mainly psycho education can be given to prevent the students from developing the Internet addiction and psychological problems. Furthermore, the government may take necessary action to regulate the Internet usage by students for the greater benefit of the nation.
