A study on the influence of internet addiction and online interpersonal influences on health-related quality of life in young Vietnamese (2017)

In the past 20 years, internet has become an integral part of our lives and an important tool for social interaction and communication [1]. Access to internet is affordable and there has been a rapid growth of users in developing countries. Excessive internet use has led to negative impact on the health of users [2].

A body of research suggests that problematic Internet use can be viewed as an addictive behavior [3, 4]. Signs and symptoms of Internet addiction (IA) include preoccupation, mood symptoms consistent with withdrawal, greater time spent (tolerance) and functional impairment or negative consequences due to excessive use. IA may include internet gaming and other forms of addictive internet usage which include excessive downloading, use of social networking sites and online shopping [5]. While internet is an integral part of our daily life, IA is increasingly more common among young people and has become a pandemic worldwide [6]. For young people, poor social support and social isolation have been shown to result in IA [7]. Furthermore, IA may also have a negative impact on social skills, and interpersonal relationship [8]. Hence, it is important to assess the relationship between online interpersonal influences and IA because young people suffering from IA are often shy [9] and have low social skills [10]. The negative consequences of low social skills associated with IA remain unknown [2]. No studies to date have explored the relationship between IA and online interpersonal influences.

IA leads to negative consequences on mental health. A meta-analysis comprising 1641 patients suffering from IA and 11210 healthy controls found that IA was significantly associated with alcohol abuse, attention deficit and hyperactivity, depression, and anxiety [5]. IA may be associated with other forms of addiction including smoking and alcohol dependence [11, 12]. Andrews et al. (2002) found that peer influences contributed to substance use among young people [13]. Besides adverse psychological problems, IA also causes physical problems including back pain and strain injury [14]. If IA is not intervened upon early, it may lead to adverse effects on both physical and mental health in young people.

In 2013, the six-nation survey was conducted and compared the prevalence of IA among young Asians in China, Hong Kong, Japan, South Korea, Malaysia, and the Philippines [15]. IA was common among young people in these Asian countries and the prevalence of IA was highest in Philippines (21%). The reason for the high prevalence of IA among young Asians may be due to the fact that they often face the conflicts between collective culture [16] and individual identity formation [17]. Online activities allow young Asians to avoid awareness of their actual self and real-life problems [16]. Young Asians may engage in online activities such as online gaming to avoid conflict between the collective culture and their identity formation [16]. In China, problematic internet use was associated with psychosomatic symptoms and life dissatisfaction [14]. In Taiwan, the risk factors for IA were male gender, mental health comorbidity, and poor social support [18]. It is important to study IA among youth in other Asian countries because young people constitute majority of internet users and some of them exhibit addictive behaviors towards internet [18]. One important country which was not included in the 2013 six-nation survey was Vietnam.

The prevalence of IA in Vietnam is unknown. Son et al. (2012) found that young male Vietnamese who were addicted to multiplayer online role-playing game had higher scores on mental disorder scale [19]. Addiction to online game does not represent the whole spectrum of IA. Vietnam is one of the fastest-growing economies and the Kinh ethnic group constituted around 86% of the population. The situation of IA remains unknown in the the Kinh ethnic group which emphasizes on family bonding and spirituality which includes the practice of ancestor worship. In 2015, Vietnam had 44.4 million internet users and is projected to grow to 55.8 million internet users in 2018 [20]. Given the high broadband penetration rate in Vietnam, there is no doubt that IA is becoming increasingly problematic among young Vietnamese. IA is relatively less studied in Vietnam as compared to other Asian countries because the health care system focuses more on physical diseases [19]. Furthermore, there is lack of data for IA in young female Vietnamese.

In this study, we surveyed the prevalence of IA and health-related quality of life (HRQOL) via internet with a specific focus on young Vietnamese who are vulnerable to IA due to access to internet and computer literacy. The objective of this study was to investigate the association of IA, online interpersonal influences and HRQOL. First, we compared the differences between young Vietnamese with and without IA. Next, we investigated the association between online behaviors, HRQOL, physical and mental health problems. We hypothesized there were significant differences between young Vietnamese with and without IA in (i) socio-demographic characteristics; (ii) different domains of online interpersonal influences; (iii) the occurrence of physical and mental health problems; (iv) HRQOL and (v) occurrence of other forms of addiction. By identifying factors associated with poor HRQOL, this study aims to identify targets for future health interventions to improve HRQOL, physical and mental health of young Vietnamese in the era of internet and online culture.

The aim of this pioneering study was to understand the interaction between IA, online interpersonal influences and HRQOL among young Vietnamese. The hypotheses that there were significant differences between young Vietnamese with and without IA in different domains of online interpersonal influences, the occurrence of physical and mental health problems and HRQOL were confirmed. In contrast, the hypotheses that there were significant differences between young Vietnamese with and without IA in socio-demographic characteristics and occurrence of other forms of addiction were not confirmed.

In this study, the prevalence of IA was 21.2% and it was established by a validated questionnaire, the IAT which was able to capture essential features of IA [11]. Our prevalence rate is higher or similar than other Asian studies (the prevalence of IA in Philippines was 21% (Mak et al. 2014); Korea was 20% [31]; Taiwan was 17.9% [18]; Singapore was 17.1% [32], Hong Kong was 16.4% [15]; Malaysia was 14.1% [15]; South Korea was 9.7% [15] and Japan was 6.2% [15]). The prevalence of IA in Vietnam is higher than the prevalence of IA reported in China [15, 33]. The prevalence of IA was reported to vary widely from study to study [14]. The variations could be caused by differences in the assessment methods for IA, as well as national differences in the prevalence of IA due to underlying cultural and social differences [14]. There is a possibility that IA is an emerging problem and prevalence of IA has increased since 2009. It is of utmost importance for each country to conduct studies to measure the prevalence of IA at regular intervals.

Contrary to findings from previous Asian studies, there was no significant difference between the IA and non-IA groups in the proportion of gender although previous Asian studies reported that male gender was a risk factor for IA [14, 18]. Researchers further postulated that online games and pornography were the main reasons contributing to IA in young men. Our findings suggest that young women are equally vulnerable to IA. This observation could be due to the fact that young men and women tend to be equal in manyaspects of life including the access to internet. Further studies are required to monitor the gender differences in IA in other countries. Young Vietnamese with IA were not more likely to be cigarette smokers, water-pipe smokers and alcoholics as compared to their counterparts without IA. This can be explained by the fact that the Kinh ethnic group views smoking water-pipe as part of their cultural practices and not associated with IA.

With regard to the forms of interpersonal influences from online relationship, online relationship demonstrated significantly higher influences on behaviors and lifestyles in young Vietnamese with IA. This study also showed that young Vietnamese with IA were significantly more likely to visit places and engage in activities recommended by their online friends. These are interesting findings since no studies to date have explored online interpersonal influences on lifestyles and behaviors in young people suffering from IA. These findings serve as a reference and require further replication in other countries. This is an expected finding because young Vietnamese with IA are spending ever-increasing amounts of time on internet. Internet is the only medium for socialization because the lack of social support from family and non-online friends is the main causes of IA [7]. From the cognitive perspectives, people with IA require greater cognitive efforts to make decision [34]. As a result, they may prefer to seek advices from online peers to help them deciding on activities or visiting places. From the social perspectives, one explanation is that young people with IA feel that they are safer or more comfortable with online communications [2], especially among those who suffer from IA and loneliness [18]. As a result, young people with IA are more open to suggestions by their online friends. Not surprisingly, young Vietnamese with IA spent significantly more time on social media such as Facebook on a daily basis.

Young Vietnamese with IA were more likely to report the occurrence of having problems in self-care and usual activities, pain or discomfort, anxiety or depression. These results are in line with previous research that has shown associations between IA and minor mental health morbidity [11, 14, 18]. Our findings confirm that IA could impair psychological well-being of young Vietnamese. Cao et al. (2009) suggested that excessive internet use often lead to heightened psychological arousal and result in health problems [14]. Primary care physicians need to assess physical and mental health status of young people with IA in developing countries. In addition, with regards to the HRQOL, young Vietnamese with IA had significantly lower scores in the EQ-5D index and EQ-5D VAS. These findings correspond to previous reports on IA and dissatisfaction with life [14]. The current finding confirms the results of previous research which found that long duration of internet use leads to functioning impairments [18]. The regression analysis showed that IA and alcohol dependence contribute to poor HRQOL in young Vietnamese. This finding suggests that IA could be as harmful as alcoholism.

This study found that IA is a common problem in young Vietnamese and the prevalence of IA is among the highest as compared to other Asian countries. Both genders are at risk for IA. Our study has contributed to the understanding of important interactions between IA, online interpersonal influences and HRQOL in young Vietnamese. The findings help health professionals to design evidence-based intervention to tackle adverse online interpersonal influences associated with IA in young Vietnamese.
