Abstract

Smartphones have become a new means of communication and a major method of obtaining information. Dependence on or the excessive use of smartphones may affect health in the long term. However, little attention has been focused on smartphone use and dependence among undergraduates. Therefore, this study investigated the smartphone use behavior of Taiwanese undergraduates and their dependence on smartphones. A cross-sectional study design with a structured questionnaire was used for undergraduates aged ≥ 20 years from four universities. The results suggested that the majority of participants, particularly women, experienced physical discomfort caused by smartphone use. Moreover, the participants exhibited a moderate to high dependence on smartphones. Smartphone use and dependence were both affected by family economic status, monthly allowance, and major. The findings indicated that health care providers, educators, and parents can play critical roles in encouraging the healthy use of smartphones among undergraduates.

1 Introduction

Cell phones have undoubtedly changed and affected people’s lives. First-generation (1G) cell phones used analog signals and could transmit only voice. Second-generation (2G) cell phones were introduced with a more efficient and stable operating system and additional features, such as text messages, a calendar, Bluetooth transmission, and a camera. Third-generation (3G) mobile telecommunication technology enabled cell phones to use a universal wireless communication system and support services including wireless Internet access and multimedia applications [52]. Because of progress in mobile communications and wireless technology, smartphones, using 3G telecommunication technology, now have access to the Internet, multimedia applications, and data processing systems as well as entertainment features, resulting in a rapid increase in the number of smartphone users, including young people, worldwide over the past few years [19]. For instance, in the United States, the rate of smartphone ownership among people aged 18–24 years increased from 60% in 2012 to 75% in 2013 [4]. With Internet services, people can easily and simultaneously communicate with each other, which, in turn, changes social interactions and communication patterns [55, 66, 69]. Nevertheless, because of the excessive use of smartphones, these modern gadgets have negatively influenced physical and psychological well-being, for example, by causing loneliness [50], emotional distress [6], and sleeplessness [30]. Empirical studies on smartphone use and dependence have been conducted mainly in Western countries and few related studies have been conducted in Eastern countries, particularly Taiwan. To elucidate this issue, this study examined smartphone use and dependence among the young people in Taiwan.

2 Literature Review

2.1 Smartphone Use among Taiwanese Young People

Smartphones were introduced to Taiwan in 2007 and have influenced people’s lives through 3G technology, which offers efficiency, convenience, and mobility [43, 47, 52]. Smartphones have become a new means of communication and a major method of obtaining information in Taiwan [70]. In addition, smartphones make social networking and entertainment sites more usable and accessible [43, 56, 70]. According to a 2011 nationwide report on cell phone use among young people in Taiwan, 80% had their own cell phone, which was an increase of 20% compared with 60% of young people owning a cell phone in 2009. In addition, 93% of the young people who owned a cell phone felt anxious when their cell phone ran out of battery, when they made a call and the other person did not pick up or their cell phone use was restricted by parents or left at home [24]. The report revealed that young people in Taiwan are vulnerable to the negative effects of using cell phones, including smartphones. Undergraduates are particularly likely to become heavily dependent on their smartphones [34, 41].

Research on smartphone use and dependence among Taiwanese undergraduates is limited. Studies have mainly focused on the Internet behavior and addiction of high school students [11, 16, 25, 36, 58, 60, 67] and Internet addiction disorders and tendencies of college students [12, 17, 40, 62]. Therefore, in this study, we aimed to investigate smartphone use and dependence and thoroughly examine how demographic factors contribute to smartphone use and dependence among undergraduates in Taiwan.

2.2 Cell Phone Use among Young People

Using cell phones to manage daily communication and maintain social networks is becoming a necessity for young people [22]. The 2011 report of the Office of Communications, London showed that 65% of young people checked their cell phone when talking to others, 34% used a cell phone while eating, and 47% used a cell phone while bathing or while using restrooms. Furthermore, a report demonstrated that 43% of all American young people owning a cell phone reported they had talked on a cell phone while driving. In addition, 40% stated that they had been passengers with drivers who used a cell phone [45]. Smartphones belong to the same information and communication technology as cell phones; therefore, smartphone use should demonstrate similar phenomena and effects.

Studies have reported the reasons for which young people use cell phones. For instance, Ling and Yttri (2002) reported two factors that contributed to cell phone use, namely microcoordination and hypercoordination [42]. Microcoordination refers to using cell phones to complete a task (e.g., making appointments), whereas hypercoordination is defined as communication for expression, such as chatting. Therefore, young people spend a large amount of time on their phones to facilitate social interactions.

Oulasvirta and the colleagues (2012) reported that undergraduate respondents spent 2.7 hours a day checking emails, Facebook, update feeds, and news headlines by using smartphones [54]. In addition, Balakrishnan and Raj (2012) investigated cell phone use among the students of a Malaysian university on the basis of the uses and gratifications theory [3]. The authors observed that the students used cell phones for socialization and privacy from their parents. The students generally used their cell phones between 5 and 10 times per day.

Kamibeppu and Sugiura (2005) demonstrated that the e-mail applications of cell phones were frequently used by students in Japan, with the majority of students exchanging e-mails with schoolmates >10 times a day. The students preferred to email through cell phones instead of direct communication because they found it easier to express their feelings [31]. By contrast, Brown, Campbell and Ling (2011) revealed that young people in the United States were likely to use the text messaging feature of cell phones to communicate with peers, with 100 text messages sent per day [9]. Moreover, undergraduates who excessively used cell phones were inclined to report physical problems, such as prolonged sleep, sleeplessness, headache, and muscular soreness [13, 30].

The duration of cell phone ownership and the amount of money spent each month on cell phones are indicators of cell phone use. Young people spend increasing time using cell phones as the duration of ownership increases. Cell phone ownership is positively associated with the number of calls received and feeling that a cell phone is a necessity in daily life [1]. In addition, the monthly cell phone expenditure has a positive relationship with cell phone use [59]. Financially constrained people believe that the main barrier to increased cell phone use is the cost; therefore, they reduce the cost of cell phone use by making few outgoing calls, misscalling [3, 21], or using prepaid services [26]. Wilska (2003) demonstrated that parents generally paid the cell phone bills of their children [68]. However, Coogan and Kangas (2001) revealed that parents typically limited the bill amount to prevent their children from using cell phones excessively, thereby influencing the patterns of mobile use in the young people [18].

Young people were shown to use cell phones while driving [65]. Furthermore, Nemme and White (2010) revealed that young people preferred to read text messages than send text messages while driving because the behavior of sending text messages is less accepted by society [53]. Consequently, the number of text messages sent was less than that received while driving.

Researchers have also investigated how user demographics influence cell phone use patterns. Gender differences in cell phone use were revealed; female university students were more likely to make calls for social interaction [69] and regularly have conversations over cell phones [5, 63]. Affordability affects cell phone use; young people in high-income households were more likely to use cell phones [23, 41, 59]. Moreover, young people with a higher monthly allowance were more likely to use cell phones [23].

Based on the aforementioned studies, the first research question of this study was proposed as follows:

RQ1: How do the characteristics of Taiwanese students influence their smartphone use?

2.3 Cell Phone Dependence Among Young People

Smartphone use has sparked the “phubber” phenomenon. “Phubbers” ignore people who are actually present in a social setting because they use a smartphone excessively, which, in turn, leads to various concerns, including dependence. According to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text revision (DSM-IV-TR), substance abuse includes behavioral and physical dependence [2]. Behavioral dependence refers to substance-seeking activities and the related evidence of pathological use patterns; physical dependence is defined as the physical effects of multiple episodes of substance use, including tolerance and withdrawal. Accordingly, dependence on information technology, such as cell phones and the Internet, is considered behavioral dependence because of the nonchemical human–machine interaction [7, 10]. In addition, technological dependence has characteristics such as intensive use, a craving for technology-related activities, lack of impulse control, mood instability, tolerance, abstinence, interpersonal conflicts, recurrence [27, 28, 72], and poor time management [8]. Oulasvirta et al. (2012) demonstrated that spending 3 hours per day with smartphones would interfere with daily routine [54]. In addition, studies have revealed that people who consider themselves dependent on cell phones are more likely to be depressed [71] and lonely [61].

Research has shown that demographics influence dependence on smartphones. For instance, Morahan-Martin and Schumacher (2000) showed that male college students were likely to use applications such as Internet games and consequently have problematic use of computer technology [50]. Women have a higher level of dependence on cell phones than men do [39, 63], possibly because the female attitude toward computer technology has become more positive [57]. In addition, the monthly allowance and household income [39] and the major in which students studied [38] were positively associated with cell phone dependence.

Based on the aforementioned studies, the second research question of this study was proposed as follows:

RQ2: How do the characteristics of Taiwanese students influence their smartphone dependence?

3 Methods

3.1 Design

This cross-sectional study employed a structured questionnaire to collect data. Before collecting data, the study protocol was approved by the Institutional Review Board of authors’ university, which waived the need for a written consent. The researchers first contacted the administrative units of universities for permission and arranged to collect data. The researchers then personally explained the research purposes, questionnaire content, and instructions to complete the questionnaire to the target students. After obtaining their verbal consent, the students were given the questionnaire and an envelope used to maintain the students’ privacy. During data collection, the participants could quit at any time if they felt uncomfortable or were unwilling to answer the questions. To increase the number of completed questionnaires, the participants received an incentive to compensate them for their time and effort. Finally, the researchers collected the envelopes containing the completed questionnaires at the end of the test.

3.2 Participants

In 2012, there were 436,812 Taiwanese undergraduates including 225,216 men and 211,596 women, aged over 20 years [48]. According to the sampling method of Krejcie and Morgan (1970), with a 95% confidence level and a 5% margin of error, the minimum sample size for this study should be 385 participants [33]. This study used convenience sampling to collect data from four universities in Northern Taiwan during the period from October to December 2013. A total of 397 students were approached and they returned the questionnaires. Among them, 22 were excluded because they did not own a smartphone. Finally, 375 students, whose ages ranged from 20 to 24 years, were included because they completed the questionnaire and were valid for analysis (completion rate = 94%).

3.3 Instruments

The contents of the self-administered structured questionnaire were based on the foreign and domestic literature. Six experts in public health, health education, and health care professions were invited to examine the relevancy, appropriateness, necessity, and clarity of the questionnaire. The questionnaire was also reviewed and modified according to the item-level content validity index (I-CVI) [44]. The majority of I-CVI values ranged from 0.83 to 1.00. Only 4 items regarding dependence on smartphones had I-CVI values of 0.66. These 4 items were modified according to the opinions of the experts. Moreover, a pilot test (n = 43) was conducted on September 13, 2013 at a university in Northern Taiwan to establish the reliability of the scale of dependence on smartphones. The pilot test results showed that the Cronbach’s α of the scale was 0.92. The contents of the final questionnaire are described as follows.

3.3.1 Smartphone use

To assess smartphone use patterns, 5 items were included in this section: the duration of using a smartphone, monthly cost of using a smartphone, payer of the smartphone bill, use of a smartphone while driving a car or scooter, and experience of physical discomfort (e.g., myofascial pain syndrome, dry eye syndrome, or joint pains) because of using a smartphone. The duration of using a smartphone was categorized from <1 year to >5 years. Smartphone cost per month included choices from ≤ NT$300 to ≥ NT$3,001. The payer of the smartphone bill included “self,” “parents,” “siblings,” “other relatives,” and “boyfriend or girlfriend.” Regarding the items “had used a smartphone while driving a car or a scooter” and “had experienced physical discomfort,” respondents were asked to respond either “yes” or “no.”

3.3.2 Dependence on smartphones

To assess the level of dependence on smartphones, this scale included 25 items, with a 5-point Likert scale (1 = strongly disagree; 5 = strongly agree), that included tolerance for smartphone use, compulsive smartphone use, withdrawal, social interactions, and self-management, which were based on the literature [35, 64]. The total possible score ranged from 25–125, with a higher score indicating a higher level of dependence on smartphones. Tolerance for smartphone use was measured by 4 items. An example item was “I realize that I spend more time using a smartphone now than I did 3 months ago.” Compulsive smartphone use was measured by 6 items. An example item was “I cannot control my impulse to use a smartphone.” Withdrawal was measured by 4 items. An example item was “I feel anxious when there is no signal.” Social interactions were measured by 5 items. An example item was “I feel I got more friends after I started using a smartphone.” Self-management was measured by 6 items. An example item was “I often have difficulty staying on my schedule due to use of a smartphone.” In this study sample, the Cronbach’s α for dependence on smartphones was 0.92, indicating satisfactory internal consistency.

3.3.3 Demographics

Participants reported four characteristics: gender, the major in which they studied, monthly allowance, and monthly household income. Gender was coded as male or female. The majors included Medical Science and Engineering, Management and Business, and Liberal Arts and Foreign Languages. The item assessing monthly allowance included choices ranging from “none” to ≥ NT$12,001. Monthly household income was reported from “none” to ≥ NT$150,001.

4 Analysis

Statistical Analysis System (SAS, version 9.3; SAS Institute Inc., Cary, NC, USA) was used to analyze statistical data. A chi-square test was used to compare participant characteristics and smartphone use; however, several variables had values of <5. Based on Munro’s (2004) principles, the variables were collapsed to form dichotomous or fewer measures, including years of smartphone use (<3years and ≥ 3years), smartphone cost per month (≤NT$500 and >NT$500), bill payer (“parents” and “self or other relatives”), monthly allowance (≤NT$6,000, NT$6,001–9,000, and ≥NT$9,001), and monthly household income (≤NT$50,000, NT$50,001–100,000, and ≥NT$100,001) [51, 64]. A t test and analysis of variance (ANOVA) with pairwise comparisons, using the Sidak method, were used to analyze participant characteristics and smartphone dependence. Scheffe’s post hoc test and Fisher’s protected least significant difference (LSD) test were also used. The significance level was set at p < 0.05.

Among the participants, 62.14% had used a smartphone for ≥1years, <3years. Most of the participants (39.74%) paid NT$501–1,000 for their monthly phone bill, and most of the phone bills (74.67%) were paid by parents. Furthermore, although 64.00% of the participants stated that they never used a smartphone while driving a car or scooter, 36% of participants had used a smartphone while driving a car or scooter. Approximately 76% of the participants experienced physical discomfort because of using a smartphone. The mean value of dependence on smartphones within the past 3 months was 73.42 (standard deviation (SD) = 16.54; range = 25–125), indicating a moderate to high level of dependence on smartphones (Table 2).

5.2 Relationships between Participant Characteristics and Smartphone Use

Table 3 shows statistically significant differences between gender and having used a smartphone while driving a car or scooter (χ2 = 6.23, p = 0.013) and experiencing physical discomfort (χ2 = 10.79, p = 0.001); between major and smartphone cost per month (χ2 = 6.00, p = 0.049) and having used a smartphone while driving a car or scooter (χ2 = 6.86, p = 0.032); between monthly allowance and years of smartphone use (χ2 = 12.68, p = 0.002) and smartphone cost per month (χ2 = 14.60, p < 0.001); between monthly allowance and the smartphone bill payer (χ2 = 8.53, p = 0.014) and having used a smartphone while driving a car or scooter (χ2 = 7.81, p = 0.020); and between monthly household income and years of smartphone use (χ2 = 17.71, p < 0.001) and having used a smartphone while driving a car or scooter (χ2 = 9.58, p = 0.008).

5.3 Relationships Between Participant Characteristics and Smartphone Dependence

Smartphone dependence showed statistically significant differences among the major in which participants studied (F = 5.85, p < 0.01), monthly allowance (F = 3.37, p < 0.05), and monthly household income (F = 4.25, p < 0.05). According to the results of Scheffe’s post hoc test, participants from colleges of Management and Business had the highest dependence on smartphones. Participants with a monthly allowance of ≥NT$9,001 had the highest dependence on smartphones. Participants whose monthly household income was ≥NT$100,001 had a higher dependence on smartphones than those whose monthly household income was NT$50,001–100,000. On the other hand, participants whose monthly household income was ≤NT$50,000 had a higher dependence on smartphones than those whose monthly household income was NT$50,001–100,000 (Table 4).

6 Discussion

This study assessed smartphone use and dependence among undergraduates in Taiwan. Moreover, this study examined individual factors that have been identified as crucial in information and communication technology use behaviors. In this study, most of the undergraduates had a monthly allowance of NT$6,001–9,000, which was similar to the results of a national report showing that undergraduates had a monthly allowance of NT$5,000–10,000 [15]; however, the monthly household income of most of the participants was NT$50,001–80,000, which was lower than the national average monthly household income of NT$93,532 [20]. The difference may have been caused by using convenience sampling in this study.

The results showed that several individual factors were correlated with both smartphone use patterns and dependence among the undergraduates. The economic status of the family and the monthly allowance of the student are the two major factors influencing smartphone use by undergraduates. In Taiwan, most undergraduates receive a monthly allowance from their parents; therefore, undergraduates with a higher family income are likely to receive a higher monthly allowance, and, in turn, have more years of experience with smartphones, higher monthly phone bills, and more dependence on smartphones. This finding is consistent with those of previous studies, in which a higher economic status indicated more monthly telecommunication expense, more cell phone use [10, 29], and more dependence on smartphones [39]. By contrast, students having a lower monthly allowance are likely to have lower monthly smartphone expenses and lower dependence levels. Undergraduates may have a low financial capability to pay bills [13] or those having a lower monthly allowance might effectively use their allowance and control their smartphone use. These findings indicate that restricting undergraduates’ allowance might reduce their dependence on smartphones. Therefore, parents should understand and help their children to manage their allowance and smartphone use. If children excessively spend money and time on smartphones, parents can advise the children about the adverse effects of smartphone overuse. Furthermore, research has shown that undergraduates generally have maladaptive behaviors and lack knowledge about dependence and addiction [49]. Health care providers and educators can hold seminars or provide relevant information to students to help students manage their smartphone use.

Similar to the findings of Korpinen and Pääkkönen (2011), we discovered that more women than men reported experiencing physical discomfort caused by using a smartphone [32]. This difference may be explained by the different psychology and physiology of men and women [53, 59]. In addition, although we did not find a statistically significant difference between the two genders with regard to smartphone dependence, female undergraduates had a higher average score of smartphone dependence than male undergraduates did. Accordingly, women might constitute a risk group of people with a high dependence on smartphones and who suffer physical symptoms. Therefore, additional tailored interventions are required to prevent or reduce the adverse health effects of smartphone overuse among female students. Furthermore, we suggest that health care providers, parents, and educators direct students identified as having smartphone dependence to obtain appropriate treatment as well as play major roles in preventing smartphone dependence by organizing health promotion activities about using smartphones in a controlled manner at home and on campus.

This study showed that 36% of undergraduates had used a smartphone while driving a car or scooter and that women were more likely than men to use a smartphone while driving a car or scooter. Evidence has revealed that using a cell phone while driving is associated with a four-fold increase in crash risk [46] or increase in the occurrence of motorcycle accidents. [37] Although the Taiwanese government has established regulations to prohibit smartphone use while driving to prevent accidents [14], our study data indicate that the regulations do not prevent young people, particularly women, from continuing to use their smartphones while driving, possibly because of poor legal enforcement. Therefore, obeying the regulations could be promoted on campus by reminding students not to use a smartphone while driving a car or scooter.

According to the study results, students studying in different colleges had different levels of smartphone dependence; this finding is consistent with those of previous studies [38, 41]. In this study, students from colleges of Management and Business had significantly higher scores of smartphone dependence than those from other colleges. A possible reason for this difference could be that Management and Business students are often required to use electronics products, such as computers, smartphones, and tablet computers for their future business activities and career; consequently, they would have higher smartphone dependence. By contrast, Medical Science and Engineering students had lower smartphone dependence, possibly because they may be more aware of the adverse health effects of prolonged smartphone use. Such information on the responsible use and avoidance of dependence on new technology might be included in a school course, particularly for Management and Business students.

7 Limitations and Future Research

This study used a cross-sectional design to investigate the predictive factors of smartphone use and dependence among undergraduates. However, this study did not include all possible factors, such as social stress in student life and the locus of control and personality type, influencing smartphone use patterns and dependence. Future studies are required to investigate the extent to which psychosocial factors contribute to smartphone use and dependence among undergraduates. Furthermore, the study methodology was unable to verify the cause and effect among factors. An interventional approach with a longitudinal design is recommended for use in future studies to examine the cause and effect of smartphone use, smartphone dependence, and behavioral changes with smartphone use patterns. Thus, effective strategies for preventing smartphone dependence can be developed. Because of limited funds and manpower, only four universities were included. Expanding the sample size by using random sampling or big data is recommended for future studies to obtain more accurate information regarding smartphone use patterns, so that the findings can be applied to other undergraduates and more efficient strategies can be developed to reduce and prevent smartphone dependence. Furthermore, the self-administered structured questionnaire of smartphone dependence was used only by the undergraduates; consequently, common method bias may be a potential limitation. The opinions of parents and peers should be included in future studies to obtain more objective results of smartphone dependence among undergraduates.

8 Conclusion

Because of the efficiency and convenience of smartphones, an increasing number of people rely on them. In particular, smartphones have constituted a part of the lifestyle of undergraduates. In this circumstance, smartphone overuse may cause adverse health effects. The present study provides a basis for the direction of future studies in efforts to prevent or reduce the negative effects caused by this new technology. Importantly, the present study provides foundation for developing multi-faceted strategies designed to discourage the overuse of smartphones among undergraduates.
