National, Sex and Academic Discipline Difference in Smartphone Addiction: A Study of Students in Jordan, Saudi Arabia, Yemen and Sudan

The Association Between Proneness to Smartphone Addiction and Social Anxiety Among School Students and the Mediating Role of Social Support: A Call to Advance Jordanian Adolescents' Mental Health

BACKGROUND

Social anxiety is an emerging public health issue associated with significant impairment of social functioning during adolescence. Among many determinants of social anxiety, proneness to smartphone addiction may significantly contribute to the development of social anxiety. To cope with the consequential development of social anxiety, adolescent school students may rely on various forms of social support. Particularly in the Middle East, including Jordan, the relationship between proneness to smartphone addiction and adolescent social anxiety is understudied.

AIM

To examine the mediating role of social support in the relationship between proneness to smartphone addiction and social anxiety in a sample of adolescent school students.

METHODS

In this cross-sectional study, 432 adolescents were recruited via a random cluster sample from public schools across three provinces in Jordan. The data were collected face-to-face using the Social Anxiety Scale for Adolescents, the Smartphone Addiction Proneness Scale, and the Multidimensional Scale of Perceived Social Support.

RESULTS

Significantly higher levels of social anxiety were associated with females of lower economic status who reported more gaming hours and higher levels of proneness to smartphone addiction. Familial social support significantly mediated the relationship between proneness to smartphone addiction and social anxiety, controlling for the other covariates in the social anxiety model.

CONCLUSIONS

Familial social support reduced the impact of proneness to smartphone addiction on social anxiety. Nurses may supplement treatment for reducing social anxiety in adolescents suffering from proneness to smartphone addiction by fostering sources of familial social support.

Problematic Use of Smartphones and Sleep Quality Among Healthcare Workers in Qassim, Saudi Arabia

Background and objectives Problematic use of smartphones among healthcare workers can affect their performance, patient care, safety, care outcomes, and patient satisfaction. The aim of this study was to determine the prevalence of problematic use of smartphones and the relationship between the problematic use of smartphones and sleep quality among healthcare workers in Qassim, Saudi Arabia. Methods We enrolled 393 healthcare workers conveniently selected online for this cross-sectional survey. We assessed the problematic use of smartphones using the short version of the Smartphone Addiction Scale. For sleep quality, we used the Pittsburgh Sleep Quality Index (PSQI). Linear regression was used to assess the association of problematic use of smartphones with sleep quality. IBM SPSS Statistics, version 23.0 (IBM Corp., Armonk, NY) was used for analyses. Results The prevalence of smartphone addiction (SMA) was 59.0%, and 30.5% were at high risk for addiction. The mean PSQI score was 11.56 ± 2.1 out of 21. It was found that female gender was associated with poor sleep quality (adjusted B = 0.45, p-value = 0.049). On the other hand, SMA was also significantly associated with poor sleep quality (adjusted B = 0.90, p-value = 0.016). Conclusion There is a high prevalence of problematic use of smartphones among healthcare workers, which is associated with poor sleep quality. Given the significant occurrence of problematic smartphone use among healthcare professionals and its detrimental effects on sleep quality, it is crucial for public health initiatives to devise and execute suitable preventive measures, such as smartphone use policies at work and education of workers.

Cyberchondria and smartphone addiction: A correlation survey among undergraduate medical students in Egypt

BACKGROUND

There is an increase in smartphone usage globally. Cyberchondria (CYB) is characterized by excessive Internet searches for health information. Smartphone addiction is constantly rising among medical students together with CYB as a collateral emerging risk, yet there is limited research available on the topic.

METHODS

This cross-sectional study explores the rising phenomenon of smartphone addiction and its potential role in CYB among medical students in seven Egyptian universities. A total of 1435 medical students participated in completing online questionnaires that assessed smartphone addiction and CYB using the Smartphone Addiction Scale-Short Version (SAS-SV) and Cyberchondria Severity Scale (CSS-12). Multivariable regression analysis was applied to assess predictors of smartphone addiction and CYB.

RESULTS

Based on the used scales, 57.6% of students were suffering from smartphone addiction, and 85.8% exhibited a moderate degree of CYB. There was a significant positive correlation between smartphone addiction scores and CYB (p < 0.05). The multivariable regression models revealed that four factors including using Facebook, using WhatsApp, increasing time spent on the Internet per day, and a higher CYB score increase the probability of smartphone addiction. The factors that increase the probability of CYB are using Facebook, an increase in the frequency of Internet searches, a higher degree of worry about one's health or a family member's health, and being a smartphone addict.

CONCLUSION

Smartphone addiction among undergraduate medical students is prevalent. Social media use, time spent online, and smartphone addiction were linked with the risk of CYB. Regular physical activity decreases the probability of smartphone addiction. Awareness programs and increased mental and physical activities are required to help reduce smartphone addiction among youth.

Attachment Anxiety and Nomophobia: A Moderated Parallel Mediation Model

Nomophobia is the state of being anxious or disturbed when feeling disconnected from the digital world and can have a significant impact on individuals' health and well-being. Drawing upon attachment theory and the previous literature on nomophobia, this study aims to understand how attachment anxiety influences nomophobia and whether this relationship differs between males and females. In the Human Penguin Project (HPP) (N = 1221; 12 countries; participants aged ≥20 years), the Experiences in Close Relationships Questionnaire-Revised (ECR-R), the Toronto Alexithymia Scale (TAS-20), the Perceived Stress Scale (PSS), and the Nomophobia Questionnaire (NMP-Q) were used to assess attachment anxiety, alexithymia, perceived stress, and nomophobia, respectively. The results demonstrated that (1) there were significant positive correlations between attachment anxiety, nomophobia, alexithymia, and perceived stress. Additionally, (2) there was a direct and significant effect of attachment anxiety on nomophobia, and alexithymia and perceived stress partially mediated this relationship. Finally, (3) gender significantly moderated the relationship between attachment anxiety and nomophobia. Specifically, the predicted effect was significant in both males and females, but the direct effect of attachment anxiety and nomophobia was stronger in males.

Sex and national differences in internet addiction in Egypt and Saudi Arabia

BACKGROUND

Understanding individual differences in psychology, and how they relate to specific addictions, may allow society to better identify those at most risk and even enact policies to ameliorate them. Internet addiction is a growing health concern, a research focus of which is to understand individual differences and the psychology of those most susceptible to developing it. Western countries are strongly overrepresented in this regard.

METHOD

Here, sex and national differences in internet addiction are measured, using Young's 'Internet Addiction Test,' in two non-Western countries, Egypt and Saudi Arabia. >800 students aged 18 and 35 years (M = 20.65, SD = 1.48) completed a multidimensional internet addiction instrument. The instrument measures traits such as Withdrawal and Social Problems, Time Management and Performance and Reality Substitute.

RESULTS

Analyses revealed that males scored higher than females and Saudis higher than Egyptians on nearly all scales, including the total score. Factor analysis of the 20-item instrument revealed three factors, all exhibiting sex and culture differences.

CONCLUSIONS

These findings add to the body of evidence that males are higher than females in problematic internet use, as they are in addictive behaviors in general. Our findings may also imply that restrictions on male-female interaction, which are more pronounced in Saudi Arabia, may elevate the prevalence of internet addiction. The internet is also easier and cheaper to access in Saudi Arabia than in Egypt.

Smartphone addiction, gender and interpersonal attachment: A cross-sectional analytical survey in Taiwan

Overview

Smartphone use has dramatically increased worldwide, contributing to a profound change in interpersonal interactions. They have become the primary medium of human interaction, and smartphone addiction, consequently, has become a modern-day reality. Recent research on smartphone addiction has provided diverse explanations regarding the correlation between gender and addiction. Therefore, this study aims to analyse the correlation and variance among smartphone addiction, gender and interpersonal attachment.

Methods

The participants included Taiwanese citizens and the questionnaires were randomly distributed; 1190 valid questionnaires (534 males, 656 females) were collected. Descriptive statistics were computed to observe the average value and standard deviation between interpersonal attachment and gender. Next, Spearman's ρ was conducted to interpret the correlation among smartphone addiction, gender and interpersonal attachment. Finally, the participants were divided into three groups based on their pre-determined level of smartphone addiction: high, moderate and low addictions. The Analysis of variance (ANOVA) was performed based on interpersonal attachment as the independent variable to determine any statistically significant difference among the three levels.

Results

There are four patterns of interpersonal attachment: secure, avoidant, dismissing and anxious attachments. The correlation analysis revealed a significant positive correlation between interpersonal attachment and smartphone addiction (p > 0.000), while revealing no relationship between gender and smartphone addiction or gender and interpersonal attachment. Additionally, the ANOVA indicated the difference was statistically significant in the groups of high and moderate addictions; no statistical significance was identified in the group of low addiction (p < 0.204).

Conclusion

This study revealed that there was no correlation between gender and smartphone addiction, but rather, a positive correlation between smartphone addiction and interpersonal attachment. This positive correlation suggests both high and moderate addiction groups display insecurity in their interpersonal attachment. Therefore, to lower the prevalence of unhealthy smartphone addiction, maintaining healthy interpersonal relationships is suggested.

Revealing the Intellectual Structure and Evolution of Digital Addiction Research: An Integrated Bibliometric and Science Mapping Approach

The current study uses "digital addiction" as an umbrella term to refer to addiction to the Internet, social media, smartphones, digital devices, video games, or similar digital technologies. The study aims to investigate the scientific landscape of the digital addiction research field through combining bibliometric and science mapping analysis and to facilitate insight into the development and evolution of this knowledge base. Data for the analysis were extracted from the Scopus database, which covers a wide range of journal articles, with 429 articles addressing digital addiction included in the analysis. The science mapping analysis was performed over three consecutive time periods using SciMAT software to observe the thematic evolution. The results indicated that addictive behavior was the most significant theme across the three time periods. Cross-sectional studies addressing the risk factors or outcomes of addiction among adults and different sexes were prevalent during the first period (1997-2012), while interest moved to the addictive behavior of adolescents and students during the second period (2013-2017). Research during the third period (2018-2022) was driven by smartphone and social media addiction, and resilience as a preventive factor garnered more research interest than previously studied risk factors, which may indicate a perspective change by researchers. Implications are suggested for future investigations of digital addiction.

Smartphone Addiction among University Students in Light of the COVID-19 Pandemic: Prevalence, Relationship to Academic Procrastination, Quality of Life, Gender and Educational Stage

The current study aims to identify the level and proportions of smartphone addiction, and academic procrastination among university students in the light of the Corona pandemic; identify the differences in smartphone addiction, academic procrastination, and quality of life according to gender and stage of study; and revealing the predictive ability of academic procrastination and quality of life for smartphone addiction. Methods: 556 male and female students from Saudi universities participated in the study, whose ages ranged from 18 to 52 years. Measures of academic procrastination and quality of life were used, in addition to the Italian scale of smartphone addiction, which was translated and checked for validity and reliability. Results: The results revealed that 37.4% of the sample were addicted to smartphone use, while 7.7% had a high level of procrastination, and 62.8% had an average level of procrastination. The results did not show statistically significant differences in smartphone addiction and quality of life according to gender and educational stage, while there were statistically significant differences in academic procrastination according to gender in favor of males, and according to stage of education in favor of undergraduate students. The results also revealed a statistically significant positive relationship between academic procrastination and smartphone addiction, and a statistically significant negative relationship between smartphone addiction and quality of life. A negative relationship between quality of life and academic procrastination was found. The results also revealed that addiction to smartphones could be predicted through academic procrastination and quality of life.

Prevalence and predictors of nomophobia among the general population in two middle eastern countries

BACKGROUND

Nomophobia is a psychological condition caused by a fear of disconnecting from others through mobile phones.

AIM

This study aims to determine the prevalence of and predictors of nomophobia and anxiety symptoms among the general population in Saudi Arabia and Jordan.

METHODS

This study was an observational cross-sectional study using a web-based online survey distributed in two middle eastern countries (Saudi Arabia and Jordan) between Jun 24 and Jul 20, 2021. A convenience sample was used to recruit the study participants. Categorical variables were identified as frequencies and percentages. In addition, a binary logistic regression analysis was used to determine the factors associated with nomophobia symptoms. The Statistical Package for Social Science (SPSS) software, version 27 (IBM Corp, Armonk, NY, USA), analyzed the data.

RESULTS

A total of 5,191 responded to the online survey. Around (26.5%) reported that they suffer from an anxiety problem or use a treatment for anxiety. The median daily time spent using a mobile phone (IQR) (minutes) was around 210 min per day. About half of the study sample (51.2%) are diagnosed with dependence syndrome. The binary logistic regression analysis revealed that those within the age group of 30-49 years and 50 years and above) are less likely to have mobile phone dependence compared to those less than 30 years old. Females were 16% at lower risk of developing mobile phone dependence compared to males Married participants were less likely to have mobile phone dependence compared to single participants (OR: 0.62 (95% CI 0.56-0.70)), while divorced participants were at a 46% higher risk of developing mobile phone dependence.

CONCLUSION

Nomophobia prevalence among Saudi Arabia and Jordon's population is 51.2%. Several factors may predict mobile phone dependence including age, gender, marital status, and previous history of anxiety.

Parent-adolescent relationships, peer relationships, and adolescent mobile phone addiction: The mediating role of psychological needs satisfaction

INTRODUCTION

Prior studies have shown that parent-adolescent relationships and peer relationships may be important factors associated with adolescent mobile phone addiction (MPA). The present study aims to further explore the direct effects of parent-adolescent and peer relationships on adolescent MPA as well as the indirect effects through the mediating roles of autonomy, competence, and relatedness needs satisfaction.

METHODS

Our sample consisted of 1766 Chinese adolescents (53.10% male; M_age = 13.33, SD = 1.94, range from 10 to 18 years) who completed questionnaires regarding parent-adolescent relationships, peer relationships, psychological needs satisfaction, and MPA. SPSS 24.0 was used to analyze correlations among variables and Mplus 7.4 was used to test the structural equation model in this study.

RESULTS

(1) positive parent-adolescent relationships were negatively associated with adolescent MPA, while peer relationships did not show a significant association with MPA; (2) autonomy and competence needs satisfaction significantly mediated the effects of parent-adolescent and peer relationships on MPA, while the mediating role of relatedness need satisfaction between parent-adolescent and peer relationships and MPA was not significant; (3) the mediating effect of competence need satisfaction between peer relationships and MPA was significantly stronger than that between parent-adolescent relationships and MPA.

CONCLUSIONS

This study explored the different mechanisms by which parent-adolescent and peer relationships influence adolescent MPA. These discoveries may contribute to intervention and prevention programs for adolescent MPA.

Prevalence and Associated Factors of Problematic Use of Smartphones Among Adults in Qassim, Saudi Arabia: Cross-sectional Survey

Background

The Kingdom of Saudi Arabia (KSA) ranks third globally in smartphone use. Smartphones have made many aspects of life easier. However, the overuse of smartphones is associated with physical and psychosocial problems.

Objective

The aim of this paper is to estimate the prevalence and associated factors of problematic use of smartphones among adults in the Qassim region of KSA.

Methods

We enrolled 715 participants using cluster random sampling for this cross-sectional survey. We assessed the problematic use of smartphones using the short version of the Smartphone Addiction Scale.

Results

We estimated the prevalence of problematic smartphone use among adults at 64% (453/708). Multivariable logistic regression analysis suggested that students are 3 times more likely to demonstrate problematic use compared with unemployed individuals (P=.03); adults using more than five apps are 2 times more likely to demonstrate problematic use compared to those using a maximum of three apps (P=.007). Protective factors against problematic smartphone use include using apps for academic (odds ratio [OR] 0.66; P=.04) or religious needs (OR 0.55; P=.007) and having a monthly family income of 5001-10,000 SAR (Saudi Riyal; US $1300-$2700; OR 0.46; P=.01) or 10,001-20,000 SAR (US $2700-$5400; OR 0.51; P=.03) compared to the <1501 SAR (US $400) income group.

Conclusions

We reported a very high prevalence of problematic use of smartphones in KSA. Considering its negative impact on physical and psychosocial health, public health programs should develop preventive strategies.

Lower extremity muscle strength reference values for young Saudi male adults aged 21 to 23 years and their correlation with anthropometric parameters and balance

Normative reference values for muscle strength are needed for muscle strength assessment and estimation of prognosis in lower extremity related neuromuscular disorders, as muscle strength influenced by anthropometric parameters and muscle strength itself affects balance. Normative reference values for muscle strength in the Saudi Arabian population is lacking in the literature. Hence, the current study aimed to establish normative reference values for lower extremity muscle strength and to correlate these values with anthropometric parameters and balance. Lower extremity muscle strength and balance were assessed by baseline hand-held dynamometer and by forward, lateral, and oblique direction reach tests in 421 young male adults between 21 and 23 years of age. The mean and standard deviation of lower extremity strength ranged from 43.83 ± 16.92 lb to 62.07 ± 10.74 lb. Body weight, body mass index, and oblique and lateral reach distances were correlated with some knee and ankle muscle strength values. Body weight, body mass index, and balance showed significant effect on lower extremity muscle strength. Furthermore, decreased muscle strength may impair balance; the current clinical practice should evaluate body weight, body mass index, and muscle strength during the assessment process.

The effect of smartphone addiction on physical activity level in sports science undergraduates

BACKGROUND

Smartphones are thought to have many negative effects on interpersonal relationships, physical-mental health, and general functionality as well as bring many conveniences to our daily lives. This study aimed to determine the effect of smartphone addiction on physical activity level in sports science undergraduates. Secondly, comparing the physical activity level in students by gender was aimed.

METHOD

A total of 300 (134 female, 166 male) healthy university students were included in this study. The mean age of the subjects was 21.36 ± 2.33 years. The universe of the study consisted of volunteer students (Coaching Education, Physical Education and Sports Teaching, Sports Management, Recreation Departments) at the Faculty of Sport Sciences. Participants' demographic information was obtained and their physical activity levels were questioned with International Physical Activity Questionnaires (IPAQ) and smartphone addictions with the Smartphone Addiction Scale- Short Version (SAS-SV). The significance level was accepted as p < .05 in statistical evaluations.

RESULTS

According to IPAQ scores, physical activity levels of the participants were as follows; 65.3% were adequate, 32.7% low and 2% inactive. One-hundred and twenty-six participants (42%) were smartphone addicts according to the SAS-SV results. When the departments were examined within themselves, it was found that IPAQ and SAS-SV scores were negatively correlated for Physical Education and Sports Teaching (r = - 0.262; p = .021) and Sports management (r = - 0.295; p = .01).

Anxiety about COVID-19 Infection, and Its Relation to Smartphone Addiction and Demographic Variables in Middle Eastern Countries

This study explores the level and frequency of anxiety about COVID-19 infection in some Middle Eastern countries, and differences in this anxiety by country, gender, workplace, and social status. Another aim was to identify the predictive power of anxiety about COVID-19 infection, daily smartphone use hours, and age in smartphone addiction. The participants were 651 males and females from Jordan, Saudi Arabia, the United Arab Emirates, and Egypt. The participants’ ages ranged between 18 and 73 years (M 33.36, SD = 10.69). A questionnaire developed by the authors was used to examine anxiety about COVID-19 infection. Furthermore, the Italian Smartphone Addiction Inventory was used after being translated, adapted, and validated for the purposes of the present study. The results revealed that the percentages of participants with high, average, and low anxiety about COVID-19 infection were 10.3%, 37.3%, and 52.4%, respectively. The mean scores of anxiety about COVID-19 infection in the four countries were average: Egypt (M = 2.655), Saudi Arabia (M = 2.458), the United Arab Emirates (M = 2.413), and Jordan (M = 2.336). Significant differences in anxiety about COVID-19 infection were found between Egypt and Jordan, in favor of Egypt. Significant gender differences were found in favor of females in the Jordanian and Egyptian samples, and in favor of males in the Emirati sample. No significant differences were found regarding workplace and social status. The results also revealed a significant positive relationship between anxiety about COVID-19 infection, daily smartphone use hours, and age on the one hand, and smartphone addiction on the other. The strongest predictor of smartphone addiction was anxiety about COVID-19 infection, followed by daily use hours. Age did not significantly contribute to the prediction of smartphone addiction. The study findings shed light on the psychological health and cognitive aspects of anxiety about COVID-19 infection and its relation to smartphone addiction.

Smartphone Use Among University Students During COVID-19 Quarantine: An Ethical Trigger

To reduce the spread of COVID-19, Jordan enforced 10 weeks of home quarantine in the spring of 2020. A cross-sectional study was designed to assess this extended quarantine's effect on smartphone addiction levels among undergraduates. A random sample of 6,157 undergraduates completed an online questionnaire (mean age 19.79 ± 1.67 years; males 28.7%). The questionnaire contains different sections to collect socio-demographic, socio-economic, academic, quarantine-related information, and smartphone usage. The smartphone addiction scale-short version was used to assess the degree of addiction during the quarantine. The mean addiction score across the whole sample was 35.66 ± 12.08, while the prevalence of addiction among participants was 62.4% (63.5% in males and 61.9% in females). The majority of the participants (85%) reported that their smartphone usage during the quarantine increased or greatly increased (27.6 and 57.2%, respectively), with some 42% using their smartphones for more than 6 h a day. Nevertheless, three-quarters of the students wished to reduce their smartphone usage. Several demographic and quarantine factors have been assessed, and students' gender, the field of study, parental education, household income in addition to the location of quarantine (urban, rural) and the house specifications (apartment, independent house, with/without a garden) showed statistically significant associations with smartphone addiction during the quarantine. Female students, students studying scientific- and medical-related majors compared to those studying humanity majors, those with higher incomes, those who had been quarantined in an apartment without a garden, and those who lived in urban areas showed significantly higher addiction scores.

Does the smartphone use affect the determination of daily goals: A nursing students' example?

PURPOSE

To examine how the risky use of smartphone in nursing students affects their daily goals.

DESIGN AND METHODS

A total of 419 nursing students participated in this study. A Descriptive Data Form, Smartphone Addiction Scale-Short Version, and Daily Goals Scale were used to collect the data.

FINDINGS

According to our study results; students who are afraid of forgetting or losing their phone have a higher risk of being smartphone addiction. As the risks of students' smartphone addiction increase, their daily goal setting levels decreased.

PRACTICE IMPLICATIONS

The risky use of smartphone effects negatively daily goals setting. Education and counseling programs that will prevent the risky use of smartphones and the associated risk of addiction should be provided for nursing students.

Effects of personality disorders and attitudes towards social networking services: evidence from family business successors in the Arab world

Purpose

This paper examines the effect of personality disorders, namely loneliness and shyness, on the family business successors' attitude towards social networking services (SNS).

Design/methodology/approach

In this study the personality disorder and attitude towards using WhatsApp are analysed in a sample of 511 family business successors, aged 18 and up to more than 50 years. Participants completed questionnaires designed for the purposes of the study specifically using for loneliness factor the UCLA Loneliness Scale (Russell et al., 1978) and for shyness the Sociability Scale (Cheek and Buss, 1981). We use two statistical methods: the first statistical technique is an exploratory factor analysis to show that shyness can be measured down into two dimensions (1) lack of confidence and (2) hesitancy, while loneliness also can be measured into the two dimensions: (1) amiability and (2) abandonment. The second statistical method uses structural equation modelling (SEM) to fit the data to the proposed model.

Findings

The results indicate that neither a lack of confidence nor amiability has a significant effect on the attitude towards instant messaging, while hesitancy and abandonment both have significant effects on attitude. Moreover, abandonment has a stronger effect on attitude than hesitancy.

Research limitations/implications

In this study were not included other related social disorders that other scholars normally study in such projects. For example, narcissism, addiction and socially anxious are very important and have results that conflict with ours.

Originality/value

The causal relations between the two independent factors of shyness and loneliness and the dependent factor of attitude towards using an Internet and SNS in family businesses from the Arab world have not yet been clearly and fully explored. This study aims to fill this gap through studying the impact of personality disorder (loneliness and shyness) on attitude to use SNS by the successors of family businesses.

Effect of the mobile phone-related background on inhibitory control of problematic mobile phone use: An event-related potentials study

The present study aims to provide electrophysiological evidence for deficient inhibitory control in problematic mobile phone use and to investigate whether reduced inhibition is more pronounced during exposure to a mobile phone related background cue. A screen scale of smartphone addiction was completed by 227 college students, and finally an experimental group and a control group consisting of 20 problematic mobile phone users and 19 controls were included in the study. Event-related potentials were recorded during a backgrounded Go/NoGo task performed by those two groups, in which either a frequent Go signal (letter "M") or a rare NoGo signal (letter "W") was superimposed on three different background cues: neutral, mobile phone application-related and mobile phone using-related pictures. Results showed that problematic mobile phone users performed more commission errors than controls following mobile phone application background. Furthermore, problematic mobile phone users displayed a weaker NoGo P3 amplitude than controls on the mobile phone application background. The result might suggest that there is no general impairment of inhibitory control in problematic mobile phone use. The deficient inhibitory control on behavioral and psychophysiological level appeared merely in the mobile phone-related background. Such deficient stimuli-specific inhibitory control appears at the late stage of inhibitory control. Prevention programs should be designed to curtail exposure to the mobile phone-related stimulus and enhance cognitive control of potential problematic mobile phone users.

Translation of the Chinese Version of the Nomophobia Questionnaire and Its Validation Among College Students: Factor Analysis

Background

Nomophobia or phobia of no mobile phone is the fear of being without a mobile phone or being unable to contact others via a mobile phone. It is a newly emerging psychiatric disorder among mobile phone users.

Objective

There are no psychometric scales available in China for examining nomophobia, although China has become the largest mobile phone handset consumer market in the world. Therefore, this study aimed to translate the original English version of a psychometric scale into Chinese and further examine its reliability and validity among Chinese college students.

Methods

The original version of the Nomophobia Questionnaire (NMP-Q) was first translated into Chinese using the backward and forward translation procedure. An exploratory factor analysis (a principal component analysis plus varimax rotation) and a confirmatory factor analysis (CFA) were performed to examine the underlying factor structure of the translated questionnaire. The internal consistency reliability of the scale was determined by computing the Cronbach alpha coefficient, the test-retest reliability, and the corrected item-total correlation. A multivariate regression analysis was used for examining associations between nomophobia and independent variables among the college students.

Results

A total of 2000 participants were included in the study. Their ages ranged from 16 to 25 years, with 51.95% (1039/2000) being male participants. The Chinese version of NMP-Q retained 18 items. The eigenvalues, total variance explained, and scree plot jointly support a 4-factor structure of the translated questionnaire. The CFA reached the adaptive standard, and the discriminant validity of the scale was good. The Cronbach alpha coefficient of this scale was .925, and the Cronbach alpha coefficients of the subscales were .882, .843, .895, and .818. The test-retest reliability was 0.947. Corrected item-total correlation ranged from 0.539 to 0.663. The significant predictors for each of the dimensions of nomophobia and total score of the questionnaire were the average number of hours spent on a mobile phone daily and gender.

Conclusions

The Chinese version of the NMP-Q exhibited satisfactory psychometric properties.

Prevalence and Correlates of Excessive Smartphone Use among Medical Students: A Cross-sectional Study

BACKGROUND

Increasing smartphone use has led to the introduction of smartphone addiction as a behavioral addiction with detrimental effects on health. This phenomenon has not been widely studied in the Indian context. This study assessed the rate of smartphone addiction in a sample of medical students, with a focus on its correlation with sleep quality and stress levels.

METHODS

A cross-sectional study was conducted between November 2016 and January 2017 in 195 medical students. Their smartphone use, level of smartphone addiction, sleep quality, and perceived stress levels were measured using the Smartphone Addiction Scale-Short Version (SAS-SV), the Pittsburgh Sleep Quality Index (PSQI), and the Perceived Stress Scale (PSS-10), respectively.

RESULTS

Of the 195 students, 90 (46.15%) had smartphone addiction as per the scale. A self-reported feeling of having smartphone addiction, use of the smartphone right before sleeping, PSS scores, and PSQI scores were found to be significantly associated with the SAS-SV scores. Significant positive correlations were observed between the SAS-SV and PSS-10 scores, and the SAS-SV and PSQI scores.

CONCLUSIONS

There is a high magnitude of smartphone addiction in medical students of a college in Western Maharashtra. The significant association of this addiction with poorer sleep quality and higher perceived stress is a cause for concern. The high self-awareness among students about having smartphone addiction is promising. However, further studies are required to determine whether this self-awareness leads to treatment seeking. Further studies are required to explore our finding of the association of smartphone addiction with using the smartphone before sleeping.
