Addictive personality and problematic mobile phone use

How physical exercise influences academic burnout among Chinese "Double Non" college students: the chain mediation role of mobile phone addiction and learning engagement

Background

With mental anxiety caused by the COVID-19 pandemic, the trend of "lying down" has become increasingly prevalent among Chinese college students such as not thinking ahead, decadent abandonment, and being weak daily. Particularly, Chinese "Double Non" college students are more likely to face academic burnout (AB) due to lower school satisfaction and after-degree employment ratio, in comparison to "Double First-Class" college students.

Objectives

In view of this, the present study examined the structural relationships of physical exercise (PE), mobile phone addiction (MPA), learning engagement (LE), and AB among Chinese "Double Non" college students, aiming at exploring corresponding mechanism to provide supportive guidance for alleviating potential AB.

Methods

This study adopted a cross-sectional survey approach among the sample of "Double Non" college students in China. We recruited 930 participants (272 men and 658 women) in the second half of the 2022-2023 academic year, all of whom completed questionnaires involving Physical Exercise Rating Scale, Mobile Phone Dependence Index Scale, Utrecht Work Engagement Scale-Student, and Maslach Burnout Inventory-Student Survey. A series of statistical analyses, including descriptive statistics, bivariate correlations, and direct and indirect effects among study variables, were proceeded based on the collected data.

Results

The results showed that PE can not only directly and negatively influence AB, but also indirectly and negatively influence AB through the mediation of MPA as well as the chain mediation of both MPA and LE. While PE had no significantly indirect effect on AB via LE.

Discussion

Physical exercise was proved to be an effective way to reduce MPA and then enhance LE, consequently leading to decreased AB in Chinese "Double Non" college students. The findings were discussed in light of related research, and implications and future directions were put forward for application in potential theoretical research and educational practice.

Psychometric properties of the Problematic Online Gaming Questionnaire (POGQ) in a Moroccan sample of university students

BACKGROUND

The Problematic Online Gaming Questionnaire (POGQ) instrument consists of 18 items with a six-factor structure. This questionnaire is widely utilized to measure the degree of problematic online gaming, but the scale has not, up to date, been validated in Arabic language. This study aimed to assess POGQ scale validity and reliability in Moroccan context.

METHODS

The research was conducted from April to June 2023 using an online questionnaire. The selected sample involved Moroccan university students. Data were analyzed in two successive phases. First, exploratory factor analysis (EFA) was used to assess the factor structure in the first sample (n1 = 143). Then, this structure was confirmed in the second sample (n2 = 313) using confirmatory factor analysis (CFA).

RESULTS

The EFA and CFA results demonstrated that the POGQ has a six-factor structure explained 72% of the total variance. The results of this analysis provided an optimal fit to the data confirming a good performance of the measurement model (χ² = 243.6; CFI = 0.981; TLI = 0.976; RMSEA = 0.048; NFI = 0.964; IFI = 0. 981; SRMR = 0.022). The instrument showed sufficient reliability and convergent validity demonstrated by acceptable values of composite reliability (CR = 0.68-0.90), and average variance extracted (AVE = 0.50-0.75), respectively. Finally, the Arabic version of POGQ was found to have a high test-retest reliability.

CONCLUSIONS

The Arabic version of POGQ revealed adequate psychometric properties. As a result, the instrument might be used to measure the degree of problematic online gaming. The use of the POGQ is expected to further promote research on online game dependence treatment and prevention.

Problematic Smartphone Use and Its Relationship With Anxiety and Suicidal Ideation Among South Korean Adolescents

OBJECTIVE

This study aimed to investigate the prevalence of problematic smartphone use (PSU) among adolescents and its association with anxiety and suicidal ideation.

METHODS

The 16th cross-sectional, population-based Korea Youth Risk Behavior Web-Based Survey was administered in 2020 and included 54,948 adolescents. We used the Korean version of the smartphone overdependence scale and the 7-item Generalized Anxiety Disorder scale to assess PSU and anxiety. Suicidal ideation was assessed through responses to the self-report question. Multiple logistic regression analyses with complex sampling were conducted to identify the association of PSU with anxiety and suicidal ideation.

RESULTS

In total, 25.1% of the adolescents reported PSU, 33.2% had anxiety symptoms, and 10.9% had seriously considered suicide during the past 12 months. Girls with PSU had a higher risk of anxiety (adjusted odds ratio [aOR], 2.81; 95% confidence interval [CI], 2.65 to 2.97) and suicidal ideation (aOR, 1.77; 95% CI, 1.64 to 1.91) than non-PSU girls. Boys with PSU reported more anxiety (aOR, 2.89; 95% CI, 2.72 to 3.07) and suicidal ideation (aOR, 1.82; 95% CI, 1.66 to 1.99) than the non-PSU group. In addition, girls with the lowest household income reported more suicidal ideation than girls with the highest household income (aOR, 3.40; 95% CI, 2.69 to 4.28).

CONCLUSION

This study demonstrated the prevalence of PSU among South Korean adolescents in 2020. The prioritization of the detection of PSU and the identification of psychological factors may help improve the diagnosis and management of mental health problems and potentially yield significant psychosocial benefits.

How is the problematic smartphone use affected by social support? A research model supported by the mediation of Ikigai

Social support and ikigai (making life worthwhile) have positive effects on problematic smartphone use and are seen to be related to each other. However, what mediates these relationships has not been adequately analyzed. This study aims to examine how the effect between social support and problematic smartphone use occurs by suggesting the mediator role of ikigai. The study was designed as quantitative and cross-sectional, and 1189 university participants aged 18 and over were reached online. The multidimensional scale of perceived social support, ikigai-9 scale, smartphone application-based addiction scale and sociodemographic information form were used as data collection tools in the study. The data obtained were carried out using SPSS 24 and Amos 25 statistical programs. Established hypotheses were tested with correlation, multiple regression and mediation analyzes. The results confirmed that social support was positively associated with ikigai, and ikigai was negatively associated with problematic smartphone use. In addition, interaction analyzes found that ikigai had a mediating effect. These findings show the importance of implementing specific applications based on the meaning and purpose of life (ikigai), especially for vulnerable groups, to minimize the problems that may arise with the excessive use of smartphones.

Insecure Attachment Styles and Phubbing: The Mediating Role of Problematic Smartphone Use

Lately, increasing concern has focused on the incessant and intrusive use of smartphones across a wide range of interpersonal and relational contexts. Of concern is that many people appear to snub someone during face-to-face interactions by focusing more on their smartphone than on their relational partner, namely, phubbing. Individuals with insecure attachment styles may phub their intimate others more often. However, such relationships have not been examined. This study used a cross-sectional design to examine key relationships between insecure attachment styles on phubbing. An online survey was conducted to examine the relationships between the variables of this study ( $N=444$ , 72% female: mean age 20). The analyses revealed both anxious-preoccupied and dismissive-avoidant attachment styles to be positively associated with phubbing. Moreover, both insecure attachment styles indirectly predicted phubbing through problematic smartphone use (PSU). Insecure attachment styles appear to impact how often people phub others within intimate relationships, and further, PSU may function as a mechanism linking these insecure attachment styles with phubbing.

Resilience and problematic smartphone use: a moderated mediation model

BACKGROUND

Problematic smartphone use (PSU) is adversely correlated with resilience. To completely comprehend the mechanism underlying this relationship, however, more investigation is required.

METHODS

For this cross-sectional study, the method of stratified random cluster sampling was applied. 834 Chinese undergraduate students (aged 17 to 24) were recruited, and self-reported questionnaires were administered to measure their levels of resilience, perceived social support, the sense of school belonging, and habitual and problematic smartphone use.

RESULTS

The findings showed that resilience both directly and indirectly predicted PSU through perceived social support and the sense of school belonging. Additionally, there were significant moderating effects of habitual smartphone use between resilience and perceived social support, the sense of school belonging, and PSU.

CONCLUSIONS

Our research identified the negative influence of resilience on PSU, and specifically, highlighted the mediation effects of perceived social support and the sense of school belonging. Of significance, we also found the moderation effect of habitual smartphone use in the development of PSU.

In WAZE we trust? GPS-based navigation application users’ behavior and patterns of dependency

Functional technological applications have become an integral part of our lives changing our patterns of reasoning and behavior. The current study examines whether, how and why use of WAZE app, a popular GPS-based navigation application, demonstrate behaviors and patterns which resemble those of technological dependency. We conducted semi-structured in-depth interviews with 50 WAZE users. The questions took inspiration from the model of IT addiction, which identifies six behavioral parameters: withdrawal, conflict, mood modification, relapse, tolerance, and saliency. The novelty of the study lies in the evidence of patterns and behaviors which resemble technological dependency on the WAZE app. The findings indicate that WAZE app satisfies users’ needs driven by functionality. Four behavioral characteristics associated with IT addiction are applicable to WAZE users: mood modification, conflict, relapse, and withdrawal. The study concludes that functional technological applications may trigger behavioral indicators of technological addiction.

The associations between smartphone addiction and self-esteem, self-control, and social support among Chinese adolescents: A meta-analysis

Background

Smartphone addiction has become a social problem that affects the healthy growth of adolescents, and it is frequently reported to be correlated with self-esteem, self-control, and social support among adolescents.

Methods

A meta-analysis was conducted by searching the PubMed, Web of Science, Embase, PsycINFO, PsycArticles, China National Knowledge Infrastructure (CNKI), WANFANG DATA, and Chongqing VIP Information Co., Ltd. (VIP) databases. Stata 16.0 was used to analyse the overall effect and test the moderating effect.

Results

Fifty-six studies were included, involving a total of 42,300 participants. Adolescents' smartphone addiction had a moderately negative correlation with self-esteem (r = -0.25, 95% CI = -0.29 to -0.22, p < 0.001), a strong negative correlation with self-control (r = -0.48, 95% CI = -0.53 to -0.42, p < 0.001), and a weak negative correlation with social support (r = -0.16, 95% CI = -0.23 to -0.09, p < 0.001). Moderation analysis revealed that the correlation between adolescents' smartphone addiction and self-esteem was strongest when smartphone addiction was measured with the Mobile Phone Addiction Tendency Scale for College Students (MPATS; r = -0.38). The correlation between adolescents' smartphone addiction and self-control was strongest when self-control was measured with the Middle school students' Self-control Ability Questionnaire (MSAQ; r = -0.62). The effect of dissertations on smartphone addiction, self-control, and social support among adolescents was significantly larger than that of journal articles. The correlation between adolescents' smartphone addiction and social support was strongest when smartphone addiction was measured with the Mobile Phone Addiction Index (MPAI; r = -0.24). However, the correlations between adolescents' smartphone addiction and self-esteem, self-control, and social support were not affected by age or gender.

Conclusion

There was a strong relationship between smartphone addiction and self-esteem, self-control, and social support among adolescents. In the future, longitudinal research should be carried out to better investigate the dynamic changes in therelationship between smartphone addiction and self-esteem, self-control, and social support.

Association between trajectories of problematic mobile phone use and chronotype among Chinese college students

AIMS

This study aimed to describe the prevalence of problematic mobile phone use (PMPU) and chronotype among Chinese college students, estimate PMPU development trajectories, and further examine the effect of PMPU trajectories on chronotype.

DESIGN

In a stratified cluster sampling design, PMPU and chronotype were evaluated in 999 college students from two universities in a 2-year prospective investigation from April 2019 to April 2021, and an investigation was conducted every six months (time 1 ∼ time 5, T1 ∼ T5).

PARTICIPANTS

N = 999 college students (mean age at T1: 18.8 years (SD = 1.2), 37.7% male) took part in the study.

MEASUREMENTS

The Self-rating Questionnaire for Adolescent Problematic Mobile Phone Use (SQAPMPU) and the Pittsburgh Sleep Quality Index (PSQI) were used to assess the PMPU and sleep quality of college students at each time point. The Morning and Evening Questionnaire (MEQ) was adopted to investigate the chronotype of college students at T5.

FINDINGS

The prevalence of PMPU at T1 ∼ T5 was 24.3%, 27.3%, 35.1%, 31.2% and 31.9%, respectively. The prevalence rates of morning types (M-types), neutral types (N-types), and evening types (E-types) were 19.1%, 70.8%, and 10.1%, respectively. Using latent growth mixture modelling, we identified three trajectories of PMPU: low-level (49.5%), moderate-level (38.6%), and high-level score trajectories (11.9%). Multivariate logistic regression analysis results showed that a trajectory with a high score was positively associated with E-types (P < 0.05). After stratification by gender, a high-level score trajectory was positively associated with E-types only among female college students (P < 0.05). There were sex differences in the association between trajectories of PMPU and chronotype.

CONCLUSION

Long-term symptoms of PMPU may be a potential risk factor for circadian rhythm disturbance among college students, and this effect was significantly different between genders.

Effects of exercise and psychological interventions on smartphone addiction among university students: A systematic review

Background and aims

Among the large number of studies on smartphone addiction, only a few randomized controlled trials on exercise and psychological interventions for smartphone addiction by university students have been published. This study aims to systematically investigate the impact of exercise and psychological interventions on smartphone addiction among university students.

Methods

The PRISMA guidelines were adopted for this systematic literature review. Prominent academic databases such as Web of Science, PubMed, ProQuest, Cochrane Library, China National Knowledge Infrastructure (CNKI) and PsycINFO were searched to find eligible studies published before Aug 2021. The overall quality of the articles was checked using the "QualSyst" tool by Kmet et al.

Results

From among 600 papers, 23 met the inclusion criteria and were incorporated into our systematic review. All of the studies were randomized controlled trials. The following thematic areas emerged as a result of the content analysis: study selection and design, as well as study characteristics (participants, intervention, comparisons, and outcomes).

Discussion and conclusion

The literature on exercise and psychological interventions for smartphone addiction is scarce. There is a need to introduce new interventions and to validate the effectiveness of combined interventions. Our findings suggest that exercise and psychological interventions may help to reduce smartphone addiction. This combination was more effective compare to exercise or psychological intervention on mental health and addiction among university students. Future research should combine exercise and psychological interventions, focusing on university students, especially females, who are vulnerable to smartphone addiction. Further studies should focus on the cross-section of neuropsychology, cognitive psychology, and sports science to provide combined interventions in physiological and psychological direction.

Correlations between smartphone addiction and alexithymia, attachment style, and subjective well-being: A meta-analysis

Background

Smartphone addiction (SA) has become a social problem that affects peoples’ quality of life and is frequently reported to be correlated with alexithymia, avoidant or anxious attachment styles, and subjective well-being. This study aimed to investigate the relationship between SA and alexithymia, attachment style, and subjective well-being.

Methods

A meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The following electronic databases were searched: PubMed, Web of Science, Embase, PsycINFO, PsycArticles, China National Knowledge Infrastructure (CNKI), WANFANG DATA, and Chongqing VIP Information Co., Ltd. (VIP). Stata 16.0 was used to analyze the overall effect and test the moderating effect.

Results

One hundred and ten studies were included, involving a total of 96,680 participants. SA had a significantly high positive correlation with alexithymia (r = 0.40), attachment anxiety (r = 0.37), and negative emotions (r = 0.31), and a low positive correlation with attachment avoidance (r = 0.17). In addition, there was a high negative correlation between SA and subjective well-being (r = –0.33) and a low negative correlation between SA, life satisfaction (r = –0.17), and positive emotions (r = –0.18). A moderation analysis revealed that age significantly moderated the relationship between SA and positive emotions. The tools for measuring SA significantly moderated the relationship between SA, alexithymia, attachment anxiety, and subjective well-being. Meanwhile, subjective well-being measurement tools significantly moderated the relationships between SA, subjective well-being, and negative emotions.

Conclusion

SA was closely related to alexithymia, attachment style, and subjective well-being. In the future, longitudinal research can be conducted to better investigate the dynamic changes in the relationship between them.

The Relationship between Cellphone Usage on the Physical and Mental Wellbeing of University Students: A Cross-Sectional Study

(1) Background: The study aims to examine the use of cell phones on physical and mental health status and their impact on personality among university students. (2) Methods: A cross-sectional study was conducted using a semi-structured questionnaire. The association of physical and mental health variables with the demographic variables was examined using Pearson’s correlation and χ2-test. The binary logistic regression model was further used to predict the probabilities of negative impact on personality due to excessive use of cell phones. (3) Results: A total of 400 participants participated with a mean age of 24.45 ± 3.45 years. The average eye strain was more in High cell phone users HCPU than in LCPU and that difference was significant p = 0.000. The average neck pain was more in (HCPU) than Low cell phone users (LCPU) and there was a significant difference between the two groups with p = 0.006. The average weight gain was more in HCPU than LCPU and that difference was significant p = 0.000. Considering back pain, back pain was found more in HCPU as compared to LCPU with a statistical difference at p = 0.027. Cell phone usage significantly correlated with eye strain (r = 0.577, p = 0.000), neck pain (r = 0.543, p = 0.000), back pain (r = 0.611, p = 0.000), weight gain (r = 0.423, p = 0.000), depression (r = 0.430, p = 0.000), loneliness (r = −0.276, p = 0.002), and mood disorder (r = 0.608, p = 0.000). Eye strain, neck pain, and back pain was observed more in HCPU than in LCPU. HCPU felt they gained more weight when compared to the respondents in the LCPU group. HCPU felt more changes in mood and feeling low when compared to the LCPU, while LCPU group felt more lonelier when compared to the HCPU group. (4) Conclusions: The study highlights a significant association between excess use of cell phones and negative effects on physical and mental health wellbeing. Based on the results, it is recommended that more physical activities and alternative to minimize cell phone usage should be planned for the students. Public health policy makers and stakeholder need to address the ill effects of excessive use of cell phones through novel policies., especially young students, and alternatives to reduce their cell phone activities.

The Influence of Acute Aerobic Exercise on Craving Degree for University Students with Mobile Phone Dependency: A Randomized Controlled Trial

These days, mobile phone dependency (MPD) has become one of the most imperative and impressive puzzles in the area of behavioral addictions and public health across the world, especially the individuals with MPD that might frequently crave using mobile phones themselves. The target of the current study was to determine whether moderate-intensity aerobic exercise could reduce the craving degree for mobile phones for university students with MPD by a randomized, controlled trial. Sixty Chinese undergraduates, including 30 male and 30 female students aged from 18 to 22 years (20.08 ± 1.94 years) with MPD were recruited and then randomly assigned to the exercise group (n = 30) or the control group (n = 30) with even numbers by gender and major. Participants in the exercise group were required to perform an acute moderate-intensity treadmill exercise lasting for 30 min at 45−68% heart rate reserve (HRR) with background music, while the control group were only asked to listen to the same music for 40 min without any exercise. Sport watches were employed to monitor their heart rate (HR), and the exercise group was also obliged to report their rating of perceived exertion (RPE). After completing the experimental task, a visual analog scale (VAS) was used to evaluate their craving degree for mobile phones, and an independent samples t-test was computed to reveal the difference in the scores of craving degree for mobile phones between the two groups. The results showed that the VAS score for the exercise group (3.77 ± 1.36) was significantly lower (p < 0.001) than that of the control group (6.11 ± 1.39). The findings suggested that acute moderate-intensity aerobic exercise could be an effective and reliable means to help deal with the issue of mobile phones craving for the undergraduates with MPD, and more longitudinal intervention studies and control trial designs should be conducted in the near future to further test the long-term effects of this exercise.

Exploring digital natives' mobile addiction syndrome in Taiwan: psychological issues and beyond

Purpose

This study seeks to explore digital natives' mobile usage behaviors and, in turn, develop an analytic framework that helps articulate the underlying components of mobile addiction syndrome (MAS), its severity levels and mobile usage purposes.

Design/methodology/approach

The investigation adopts a survey method and a case study. The results of the former are based on 411 random classroom observations and 205 questionnaire responses, and the insights of the latter are derived from 24 interviews and daily observations.

Findings

The findings validate five distinctive signs that constitute MAS and their significant correlations with each of the Big Five personality traits. Classroom observations confirm the prevalence of addiction tendency among digital natives in the research context. Seven levels of MAS and six different mobile usage purposes further manifest themselves from case analysis. There appears to be a sharp contrast between the addicted and non-addicted groups in their mobile purposes and behavioral patterns. Additionally, family relationships seem influential in shaping non-addictive mobile usage behaviors.

Research limitations/implications

Psychological perspectives on MAS may be important but insufficient. Empirical investigation on a global scale, especially with distinctive cross-cultural comparisons, will be highly encouraged. How MAS evolves over time should also serve as future research interests.

Practical implications

Teaching pedagogy of college education might need certain adjustments to intrigue digital natives' learning interests. Future managers might also need to adopt better performance measurements for digital natives who barely separate work from personal matters in their mobile devices.

Social implications

Parents and healthcare institutions may need to develop response mechanism to tackle this global issue at home and in society. The long-term effects of the COVID-19 pandemic on MAS might also deserve global attention.

Originality/value

The analytic framework developed provides an original mechanism that can be valuable in identifying MAS severity and associated behavioral patterns.

Impact of Mobile Game Addiction Tendency on Chinese University Students: A Hierarchical Linear Modeling Study

This study used hierarchical linear modeling (HLM) to investigate the differences in mobile game addiction tendencies among universities (i.e., double first-class universities, ordinary colleges and universities, and higher vocational colleges), and to examine the influencing factors of mobile game addiction tendency at the individual and university levels. The participants of this study were 4,024 college students who completed the Chinese Mobile Phone Game Addiction Scale, UCLA Loneliness Scale, and Positive and Negative Affect Scale. Loneliness (β = 0.052), positive emotions (β = −0.126), negative emotions (β = 0.232), and double first-class universities (γ = 0.368) significantly predicted mobile game addiction tendencies. A significant cross-level interaction between double first-class universities and other factors (i.e., positive emotions, negative emotions, and mobile game addiction) was observed. The novelty of this study is that it distinguishes the various effects of mobile phone addiction tendency at the individual and university levels.

Stress, academic burnout, smartphone use types and problematic smartphone use: The moderation effects of resilience

Few studies have investigated stress in association with social and process smartphone use and how these types of use influence problematic smartphone use during the COVID-19 pandemic; furthermore, the moderation effects of resilience have been rarely tested in this model. For these, a cross-sectional survey was conducted involving 766 Chinese undergraduate students (74.4% female; M = 20.1 years, SD = 1.15) who were measured with their levels of stress, academic burnout, smartphone use types (social/process smartphone use), resilience, and problematic smartphone use. Based on the I-PACE theory, we built a structural equation model, and the results indicated that compared with social smartphone use, process smartphone use more related to problematic smartphone use; academic burnout fully mediated between stress and process smartphone use, and between stress and problematic smartphone use. Moreover, resilience moderated between stress and academic burnout, between academic burnout and process smartphone use, and between academic burnout and problematic smartphone use. We discuss the process smartphone use as a key indicator of problematic smartphone use and the role of academic burnout for linking stress and smartphone use behaviors. In addition, interventions for enhancing resilience should be launched in the future.

Effects of Self-Management Training on Smartphone Dependence in Low to Moderate Adolescent Males’ Users

While taking advantage of the educational benefits of smartphones, students also apply this device in inappropriate ways that cause certain disciplinary and educational problems. This study examines the effect of self-management training on smartphone dependence among male high school students. Methods: In this quasi-experimental study, data were collected using the Cell Phone Addiction Scale (Koo, 2009), which was completed by the trial and control groups before and after the educational intervention. After assessing their normal distribution, the data were analysed using the Chi-square test, the independent and paired t-tests, Mann–Whitney's U-test, and the Wilcoxon test at a significance level of p < .05. Results: The results showed significant post-intervention reductions in the mean score of smartphone dependence (35.10) and its three domains, including withdrawal/tolerance (14.80), life dysfunction (8.70), and compulsion/persistence (11.60), in the trial group compared to the controls (44.80, 16.2, 12.10, and 16.50) and also in the mean score of certain applications of smartphones (p < .05). Discussion and conclusions: Despite the existing limitations, the results confirmed the efficacy of self-management training in reducing smartphone dependence in the students. The implementation of this programme is recommended for reducing dependence and promoting the proper use of this device.

Influence of eating with distractors on caloric intake of children and adolescents: a systematic review and meta-analysis of interventional controlled studies

Eating habits developed during childhood can be perpetuated along life and contribute to the emergence of disorders. We aimed to investigate the influence of distractors during experimental meals on the energy intake of children and adolescents. We followed the PRISMA guidelines and the study was registered in PROSPERO (CRD42021259946). The PICOS strategy consisted of children and adolescents (P), exposed to distractors during meals (I), compared with no distraction (C) and the outcome was energy intake (Kcal) (O) evaluated in crossover and parallel randomized clinical trials (RCTs) (S). Searches were conducted in PubMed, Scopus, Web of Science, Cochrane, Proquest, Embase, and LILACs databases. We employed RoB 2 tool and NutriGrade. Databases searches returned 9,576 references. Thirteen articles were selected (five crossover and eight parallel RCTs). Volunteers aged 3 to 17 years-old. All studies evaluated TV as distractor. Most studies presented high/moderate risk of bias. Meta-analysis of parallel RCT indicated no significant difference in energy intake while eating with TV (MD = 0.05; 95% CI -0.13 - 0.23, P = 0.57), with moderate certainty level. In conclusion, under laboratory conditions, eating with distractors seems to barely alter energy intake for children and adolescents.Supplemental data for this article is available online at https://doi.org/10.1080/10408398.2022.2055525 .

The Impact of Nomophobia, Stress, and Loneliness on Smartphone Addiction among Young Adults during and after the COVID-19 Pandemic: An Israeli Case Analysis

Technological development in recent times has dramatically changed the way people live, interact with, and consume information. Since the emergence of the first iPhone in January 2007 until today, mobile phones are used daily for a range of purposes. Using mobile phones for various purposes intensified during the COVID-19 pandemic due to isolation or government lockdown regulations. However, along with the advantages of smartphone usage there are many disadvantages such as smartphone addiction and continuous exposure to digital screens, behaviors known as PSU—problematic smartphone use. This study explores the impact of several variables on PSU: loneliness, the need for social interaction, sleep hours, fear of losing phone access (nomophobia), and stress among young adults in Israel. The variables are examined with respect to two time periods: 1. During the COVID-19 pandemic lockdowns (defined as “T1”) and 2. Following the end of the first wave of COVID-19 lockdowns (defined as “T2”). The results indicated that nomophobia, social affiliation, and sleep hours affect PSU. In addition, the indirect effect of the number of sleep hours on stress and PSU was found to be significant in T2 and in T1. The findings and their implications are discussed.

Validation of a questionnaire on problematic use of smartphones among a rural population of West Bengal

Background

While a smartphone can be a hugely productive tool, excessive use of this device can interfere with work, education, our physical and mental health, and productivity. Nowadays, we do not just use our smartphones, but we rely on them.

Objectives

The present study aims to develop and validate an instrument measuring the problematic use of smartphones among adults in a rural area of West Bengal, India.

Methods

The questionnaire on problematic use of smartphone is a self-designed tool. The items were selected by literature review. The psychometric properties of the questionnaire were assessed by content validity, construct validity, and reliability. Exploratory factor analysis was performed to identify the factors.

Results

Forty-two items were generated by literature review. After final analysis, the main questionnaire contained 28 items with 5 domains, namely "impulsive use of phone," "dependence," "impaired control," "denial," "decreased productivity," and "emotional attachment." The Cronbach's alpha value for three domains was found to be >0.7 and >0.8 for the other three domains.

Conclusion

Excessive mobile phone use is associated with various adverse consequences which is emerging as a public health problem in a large number of population in India. Problematic use of smartphone questionnaire is a valid and reliable tool to assess the pattern of mobile use among Indian population.

Self-Consistency Congruence and Smartphone Addiction in Adolescents: The Mediating Role of Subjective Well-Being and the Moderating Role of Gender

Adolescent smartphone addiction has increasingly attracted the attention of scholars because of the widespread use of internet technology in educational environments. In addition, previous studies have found that there is a complex relationship between smartphone addiction and self-consistency congruence, and subjective well-being. This research was conducted to examine whether subjective well-being would mediate the relation between self-consistency congruence and adolescent smartphone addiction, and whether gender would moderate the mediating process. A total of 1,011 Chinese adolescents completed self-report questionnaires measuring self-consistency congruence, subjective well-being, and smartphone addiction. Self-consistency congruence was shown to be a significant predictor of smartphone addiction. Furthermore, subjective well-being partially mediated the association between self-consistency congruence and adolescent smartphone addiction. Gender could moderate the mediating process; as compared with boys, girls’ self-consistency congruence and subjective well-being are more easily mediated. We envision the findings as being helpful in guiding scholars who are developing interventions to minimize smartphone addiction and its disrupting effects in adolescents.

The Relationship Between Self-Control and Internet Addiction Among Students: A Meta-Analysis

As past studies of self-control and Internet addiction showed mixed results, this meta-analysis of 83 primary studies with 80,681 participants determined whether (a) these students with less self-control had greater Internet addiction, and (b) age, culture, gender, Internet addiction measures, or year moderated these relations. We used a random-effects meta-analysis of Pearson product-moment coefficients r with Fisher’s z-transformation and tested for moderation with the homogeneity tests. The results showed a positive link between impulsivity and Internet addiction (r = 0.371, 95% CI = [0.311, 0.427]) and a negative link between restraint and Internet addiction (r = −0.362, 95% CI = [−0.414, −0.307]). The moderation analysis indicated that the correlation between impulsivity indicators and greater Internet addiction was stronger among undergraduates (18–22 years old) than among adolescents (10–17 years old). Furthermore, the negative link between a restraint indicator and Internet addiction was greater (a) among students in East Asia than those in Western Europe/North America, (b) among males than females and (c) when using the Internet addiction measures GPIUS or IAT rather than CIAS. Hence, these results indicate a negative link between self-control and Internet addiction, and this link is moderated by age, culture, gender, and Internet addiction measure.

The Italian Version of Smartphone Addiction Inventory (SPAI-I) for Adolescents: Confirmatory Factor Analysis and Relation with Self-Control and Internalized-Externalized Symptoms

The increased smartphone use in adolescence has led clinicians and researchers to carry out in-depth studies on the matter. Adolescents seem to be at risk of smartphone addiction because they are yet to develop self-control in smartphone use. This psychometric study aimed at examining the levels of validity evidence for the Smartphone Addiction Inventory-Italian (SPAI-I) version for adults, among adolescents. Confirmatory Factor Analysis confirmed the factor structure of the SPAI-I version for adults among adolescents but not the exploratory factor structure for adults of the original Smartphone Addiction Inventory (SPAI). Convergent validity was assessed by examining the relationship between SPAI-I, self-control, and internalized and externalized problems. A total of 446 Italian adolescents (mean age = 16.04, SD = 1.72, 36.3% males) completed the Self-Restraint Subscale of the Adolescent Self-Consciousness and the Strengths and Difficulties Questionnaires—with a specific focus on the subscales of internalized and externalized problems. Present findings suggested that the SPAI-I version could be used to assess smartphone overuse among adolescents according to a multidimensional perspective.

Academic Burnout and Problematic Smartphone Use During the COVID-19 Pandemic: The Effects of Anxiety and Resilience

Background: Academic burnout has been associated with problematic smartphone use. However, the mechanism underlying this relation has been inadequately explored during the COVID-19 pandemic. Materials and Methods: A total of 748 Chinese undergraduate students were recruited in the study who were measured with their levels of academic burnout, anxiety, resilience, and problematic smartphone use. Results: Our study showed that academic burnout significantly predicted problematic smartphone use both directly and indirectly via anxiety. By constructing a moderated mediation model, our study found that resilience moderated the direct impact and the second half of the indirect path (between anxiety and problematic smartphone use); however, with the moderation effects of resilience, both the indirect impact of academic burnout on problematic smartphone use via anxiety became insignificant. Conclusions: Our findings brought additional evidence on the association between academic burnout and problematic smartphone use and significantly suggested the potential solution to alleviate the influences.

The validity and reliability of Persian version of smartphone addiction questionnaire in Iran

Background

Smartphone addiction is one of the most important forms of technology addiction that has attracted the attention of all countries around the world. Many studies have been conducted in Iran on cellphone addiction among different groups. There is a necessity to have a native scale for measuring smartphone addiction in particular. Therefore, this study aimed to localize the smartphone addiction questionnaire in Iran (in the Persian language).

Methods

To assess the validity and reliability of the Persian version of the smartphone addiction scale (SAS), the questionnaire was first provided based on the standard back-translation method. Next, content validity ratio (CVR), content validity index (CVI), and face validity was evaluated for translated questionnaire. After making the necessary changes, the questionnaire was given to the community samples and was then reviewed using confirmatory factor analysis of questions grouping. Finally, the reliability of the questionnaire was investigated by the test-retest method.

Results

The CVR and CVI values of all questions were within the acceptable range. Only some of the questions in the original SAS version titled Twitter and Facebook were changed to Instagram and telegram according to experts. Internal consistency and concurrent validity of the questionnaire were confirmed by Cronbach’s alpha of 0.951. The mean correlation coefficient between the responses of the subjects, who received the questionnaire twice, was 0.946 (0.938–0.954). The grouping of questions in the subscales was changed from the original SAS version because the fitting indexes, obtained from the confirmatory factor analysis test (for example CMIN/DF greater than 5 units and RMSEA of approximately 0.07), were not acceptable.

Conclusion

The results showed that the Iranian version of the cellphone addiction questionnaire can be used as a valid, with minimal modification, tool for determining the level of smartphone addiction among Persian speakers.

Longitudinal relationships among problematic mobile phone use, bedtime procrastination, sleep quality and depressive symptoms in Chinese college students: a cross-lagged panel analysis

BACKGROUND

Cross-sectional and longitudinal studies have found that problematic mobile phone use, bedtime procrastination, sleep quality, and depressive symptoms are strongly associated. However, studies are inconsistent regarding whether problematic mobile phone use predicts depressive symptoms or vice versa, and sleep factors have been infrequently focused on in this regard. In addition, few studies have examined the longitudinal associations and directions of effects between these factors. Therefore, this study aims to explore the longitudinal relationship among problematic mobile phone use, bedtime procrastination, sleep quality, and depressive symptoms in college students.

METHODS

Overall, 1181 college students completed questionnaires on problematic mobile phone use, bedtime procrastination, sleep quality, and depressive symptoms at two time points 12 months apart. A cross-lagged model was used to examine the longitudinal relationship between these factors.

RESULTS

Cross-lagged analyses showed significant bidirectional relationships of problematic mobile phone use with bedtime procrastination and depressive symptoms. Additionally, there were also significant bidirectional relationships of sleep quality with bedtime procrastination and depressive symptoms. Problematic mobile phone use predicted subsequent sleep quality one-way, and bedtime procrastination predicted subsequent depressive symptoms one-way.

CONCLUSIONS

This study further expands our understanding of the longitudinal and bidirectional relationships among problematic mobile phone use, bedtime procrastination, sleep quality and depressive symptoms and helps school mental health educators design targeted interventions to reduce problematic mobile phone use, sleep problems, and depressive symptoms among college students.

Problematic smartphone use and affective temperaments among Lebanese young adults: scale validation and mediating role of self-esteem

BACKGROUND

Adults all over the world face serious issues from problematic smartphone use (PSU). It influences them negatively on a cognitive, behavioral, and emotional level, as well as on their tendencies and well-being. In Lebanon, the prevalence of PSU was shown to be 20.2% within the adult population, specifically with young adults (18-34 years old). This study investigates the validity and reliability of the Smartphone Addiction Scale (SAS) Arabic version. In addition, this study evaluates the association between PSU and affective temperaments and the mediating role of self-esteem in this association.

METHOD

A cross-sectional study was carried out between August and September 2020, using a sample of community-dwelling participants aged 18 to 29 years. The Smartphone Addiction Scale-Short Version was used to evaluate smartphone addiction among adolescents and adults. The five different temperaments of the patients were assessed by using the Affective temperament Scale (TEMPS-A). The Rosenberg Self-Esteem Scale was used to evaluate self-esteem.

RESULTS

461 participants were included in this study. All items of the SAS were extracted and yielded a one-factor solution with Eigenvalues > 1 (variance explained = 49.96%; α_Cronbach = 0.886). The confirmatory analysis results consolidated those obtained from the factor analysis. Higher depressive temperament (B = 0.46) was significantly associated with more smartphone addiction, whereas higher self-esteem (B =  - 0.28) was significantly associated with less smartphone addiction. Self-esteem was found to mediate the association between depressive and hyperthymic temperaments with smartphone addiction.

CONCLUSION

This study added a better understanding of the high smartphone addiction rate among adults in Lebanon. It confirms the association between affective temperaments and PSU through the mediating effect of self-esteem on Lebanese adults.

Measurement invariance of the Phubbing Scale across 20 countries

Mobile phone addiction is a robust phenomenon observed throughout the world. The social aspect of mobile phone use is crucial; therefore, phubbing is a part of the mobile phone addiction phenomenon. Phubbing is defined as ignoring an interlocutor by glancing at one's mobile phone during a face-to-face conversation. The main aim of this study was to investigate how the Phubbing Scale (containing 10 items) might vary across countries, and between genders. Data were collected in 20 countries: Belarus, Brazil, China, Croatia, Ecuador, India, Israel, Italy, Netherlands, Pakistan, Poland, Portugal, Serbia, Slovakia, Slovenia, Spain, Turkey, UK, Ukraine and USA. The mean age across the sample (N = 7696, 65.8% women, 34.2% men) was 25.32 years (SD = 9.50). The cross-cultural invariance of the scale was investigated using multigroup confirmatory factor analyses (MGCFA) as well as the invariance analyses. Additionally, data from each country were assessed individually via confirmatory factor analyses (CFAs). We obtained two factors, based on only eight of the items: (a) communication disturbances and (b) phone obsession. The 8 items Phubbing Scale.

The Effects of Children's Smartphone Addiction on Sleep Duration: The Moderating Effects of Gender and Age

BACKGROUND

Smartphones are an important part of children's and adolescents' lives, and they often spend a lot of time using them. This study aims to precisely discover the effects of smartphone addiction on sleep duration as moderated by age and gender.

MATERIALS AND METHODS

The data utilized in this study are from the 'Korean Children and Youth Panel Survey 2018' by the National Youth Policy Institute; a total of 4940 youths (2399 in grade 4 and 2541 in grade 7) from the survey were analyzed by Stata 15.0 S. The dependent variable is sleep duration, and the independent variables are the sub-factors of smartphone addiction: disturbance of adaptive functions, virtual life orientation, withdrawal, and tolerance. An independent t-test was conducted to confirm the differences in the main variables according to gender and age. Multiple regression analysis was conducted to verify the moderating effects of gender and age in the relationship between children's smartphone addiction and sleep duration.

RESULTS

First, the average sleep duration among grade 4 students was 9.17 h and grade 7 students was 7.96 h. Second, sleep duration was significantly higher for males than females, while there was no difference in smartphone addiction by gender. Third, smartphone addiction, particularly the sub-factor of tolerance significantly affected sleep duration. Fourth, age significantly affected sleep duration and gender had a moderating effect on sleep duration.

CONCLUSIONS

Interventions to develop a healthy smartphone usage culture on family and societal levels would be beneficial for increasing awareness of smartphone addiction and its adverse effects on children and adolescents. Furthermore, targeted intervention would be more effective at modifying addictive behavior and sleep duration than trying to administer blanket interventions to youths as a whole.

Negative Effects of Mobile Phone Addiction Tendency on Spontaneous Brain Microstates: Evidence From Resting-State EEG

The prevalence of mobile phone addiction (MPA) has increased rapidly in recent years, and it has had a certain negative impact on emotions (e.g., anxiety and depression) and cognitive capacities (e.g., executive control and working memory). At the level of neural circuits, the continued increase in activity in the brain regions associated with addiction leads to neural adaptations and structural changes. At present, the spontaneous brain microstates that could be negatively influenced by MPA are unclear. In this study, the temporal characteristics of four resting-state electroencephalogram (RS-EEG) microstates (MS1, MS2, MS3, and MS4) related to mobile phone addiction tendency (MPAT) were investigated using the Mobile Phone Addiction Tendency Scale (MPATS). We attempted to analyze the correlation between MPAT and corresponding microstates and provide evidence to explain the brain and behavioral changes caused by MPA. The results showed that the total score of the MPATS was positively correlated with the duration of MS1, related to phonological processing and negatively correlated with the duration of MS2, related to visual or imagery processing, and MS4, related to the attentional network; the score of the withdrawal symptoms subscale was additionally associated with duration of MS3, related to the cingulo-opercular emotional network. Based on these results, we believe that MPAT may have some negative effects on attentional networks and sensory brain networks; moreover, withdrawal symptoms may induce some negative emotions.

mHealth: Potentials and Risks for Addressing Mental Health and Well-Being Issues Among Nepali Adolescents

Adolescents are slowly being recognized as a generation, worldwide, that may require different policy approaches to improve staggering statistics on their failing well-being, including mental health. By providing the support to allow the next generation to achieve better mental health outcomes, they are going to be more economically successful and the future economic growth of nations can be better assured. Adoption of mobile-based health interventions (e.g., mHealth) has garnered a lot of attention toward this end. While mHealth interventions are growing in popularity, many researchers/policy-makers appear to have neglected assessing potential (indirect) costs/negative consequences from their use. Evidence from the developed world shows strong associations between extensive cell phone use and negative mental health outcomes, but similar research is minimal in developing world contexts. Additionally, the bulk of work on the outcomes of mobile phone use is studied using a unidirectional approach with blinders to front-end motivations. Using primary data from a large-scale, school-based survey of older adolescents in southwestern Nepal (N = 539), this work investigates such a tension between mobile/smartphone usage as a true mobile health (mHealth) opportunity in Nepal or as a potential problem, introducing additional deleterious well-being effects from over-use. Founded in Basic Psychological Needs Theory (BPNT), robust results of analyses using full structural modeling approaches (and traditional regression-based sensitivity analyses) indicate support for the BPNT framework in explaining statistically significant positive associations between bullying and anxiety, as well as, negative associations between bullying and grit, including evidence to support the mediating role of problematic mobile phone use in these relationships. More than 56% of the sample showed indicators of mild to moderate anxiety and over 10% claim experiences of bullying, coupled with over 75% of the sample scoring above the midline of a problematic mobile phone use scale, all of which motivates the relevance of our findings. Potential policy implications of these findings, and mention of other intriguing avenues for future work are further discussed.

Influence of False Self-Presentation on Mental Health and Deleting Behavior on Instagram: The Mediating Role of Perceived Popularity

The present study explored motivations (need for approval, impression management) for lying self-presentation on Instagram as well as the mental and behavioral outcomes (depression, perceived popularity, deleting behavior on Instagram) of this presentation. We also examined the differential mediational roles of perceived popularity in accounting for the association between lying self-presentation and depression. Our results showed that individuals with a strong need for approval reported higher levels of lying self-presentation. The results also revealed that lying self-presentation positively influenced depression, perceived popularity and deleting behaviors. Furthermore, we found that even if lying self-presentation increased depression, perceived popularity served as a psychological buffer against depression.

Assessing Mobile Phone Attachment: Validation of the Mobile Attachment Questionnaire in Turkish University Students and Examination of Related Variables

The main aim of this study was to adapt the Mobile Attachment Questionnaire (MAQ) to Turkish culture. It was also aimed to investigate whether mobile phone attachment (MPA) exists in Turkish university students and whether it has the main characteristics of interpersonal attachment. This study also aimed to investigate the MPA's relationship with nomophobia, smartphone addiction and materialism, and to examine the predictive power of them on MPA. The study group consisted of a total of 242 university students. Exploratory and confirmatory factor analyses were conducted to determine the structural validity of the MAQ-TR. The goodness of fit indices met the model fit requirements for the four-factor 13-item MAQ-TR. Reliability analyses results provided high internal consistency coefficients. Correlation analyses results showed that individuals highly attached to their phones experienced more severe symptoms of nomophobia and smartphone addiction and materialists were more likely to accept their phones as attachment object. Regression analysis showed that nomophobia, smartphone addiction and materialism were significant predictors of MPA. Given that MPA is an understudied concept, this study provides a starting point for future researches on problematic and non-problematic phone use.

Mobile phone applications use while driving in Ukraine: Self-reported frequencies and psychosocial factors underpinning this risky behaviour

Despite the fact that mobile phones have been transformed over the last decade into information and communication hubs that are fundamental to modern life, there is little information on how this has impacted on mobile phone use while driving. The present study was conducted in Ukraine, where this risky behaviour remains a common driving practice, despite legislative bans. A total of 220 (male = 82%; mean age = 35.53; SD = 10.54) drivers completed an online survey assessing frequency of engaging in a range of mobile phone applications while driving. Four variables of the theory of planned behaviour (general attitude and intention towards phone use while driving, social norms towards mobile phone use, perceived behavioural control, the specific beliefs about being able to engage in distracting activities and drive safely), and type A behaviour pattern were also collected. The results showed that, during the last year, 65% of drivers had read a text message and 49% had written a text using mobile phone applications. Likewise, a substantial proportion of the sample reported using social media while driving, by checking (34%), sending or typing a post (25%) on social network applications. Hierarchical stepwise regressions showed that a positive attitude towards mobile phone use while driving and beliefs about being able to drive safely and write or read a text message were significantly associated with the mobile phone applications use while driving. No associations were found between the type A behaviour pattern and mobile phone applications use.

Is psychological resilience a protective factor between motivations and excessive smartphone use?

Excessive smartphone use has recently become a topic of interest. Prior studies have suggested that psychological well-being variables and motivations are important predictors of excessive smartphone use. However, few have examined the internal mechanism of these factors in leading to excessive smartphone use. Based on Compensatory Internet Use theory, we investigated the moderating role of psychological resilience between two types of motivation — escapism and social interaction — and excessive smartphone use. Selecting 576 typical smartphone users, we found: (1) Escapism motivation and psychological resilience significantly correlate with excessive smartphone use, whereas social interaction motivation does not; (2) Psychological resilience moderates the relationship between both escapism and social interaction motivation and excessive smartphone use. Our study demonstrates the mechanism of different types of motivation and the protective effect of psychological resilience on excessive smartphone use. Thus, we emphasize resilience training that would help train people to be able to cope with life problems more effectively.

Predictors of Habitual and Addictive Smartphone Behavior in Problematic Smartphone Use

OBJECTIVE

Smartphones have become common, and problematic smartphone use (PSU) is increasing. Predictors of PSU should be identified to prevent it. Little is known about the role of content types of smartphone use as predictors of PSU. Therefore, we aimed to evaluate the predictors of two proposed concepts of PSU, namely habitual smartphone behavior (SB) and addictive SB, within the context of the application (app) categories.

METHODS

We studied 1,039 smartphone users using online surveys conducted between January 2 and 31, 2019. We employed multiple regression analysis to identify the predictors of habitual and addictive SB. We controlled for sex and age (mean=39.20).

RESULTS

Common predictors of habitual and addictive SB were the use of social networking services, games, entertainment apps, and average weekend smartphone usage time. The predictors of habitual SB were the use of web and lifestyle apps, weekly usage frequency, and sex (female) and the predictors of addictive SB were the use of shopping apps and sleep duration.

CONCLUSION

This study revealed the need to consider habitual and addictive SB in evaluating PSU. The predictors in terms of the content types of smartphone usage can be used to develop monitoring and prevention services for PSU.

Problematic mobile phone use: Validity and reliability of the Problematic Use of Mobile Phone (PUMP) Scale in a German sample

•

The German PUMP scale demonstrated very good reliability and validity and a high test-retest reliability.

•

Reasonable stability of the construct “problematic mobile phone use” was shown.

•

Problematic mobile phone use is a relevant issue in Germany.

Background

Mobile phones are ubiquitous in everyday life. Scientific studies on the problematic use of mobile phones have given initial indications of negative consequences, such as increased depression and anxiety rates and reduced sleep quality. The Problematic Use of Mobile Phone (PUMP) scale is a well evaluated, 20-item questionnaire, but a German version of the scale is still lacking.

Method

An online sample (n = 723, age 27.8 ± 11.2 years, 25.2% men) completed a German translation of the PUMP scale (PUMP-D). We conducted standard item analyses and calculated internal consistency and retest reliability. An exploratory (EFA) and a confirmatory factor analysis (CFA) were conducted using a random split of the sample, and correlations with the self-estimated time of mobile phone usage and a global self-rating of patterns of problematic use were computed. Additionally, a second sample (n = 256, age 25.0 ± 8.8 years, 34.0% men) completed the paper version of the PUMP-D scale twice to determine the 14-day retest reliability.

Results

The item-total correlations ranged from r = 0.35 (p < 0.001) to r = 0.75 (p < .001). The internal consistency was α = 0.90. The self-estimated time of usage correlated with the total value of the PUMP-D scale at r = 0.50 (p < .001). The EFA resulted in a single factor, which explained 36% of the variance. The CFA of the showed a moderate fit. The two-week retest reliability in the second sample was r_tt = 0.87 (p < .001).

Discussion

The German translation of the PUMP-D demonstrated a single factor structure, good psychometric properties and can be used in further research.

Using Smartphones When Eating Increases Caloric Intake in Young People: An Overview of the Literature

Recent literature highlights that the use of smartphones during meals increases the number of calories ingested in young people. Although the distraction interferes with physiological signals of hunger and satiety, a social facilitation effect has also been suggested. Cognition is a pivotal component in regulating food intake, and activities requiring high perceptual demands should be discouraged during meals.

Problematic Internet Use and Psychosocial Well-being: Role of Mindfulness Mediated by Self-Control and Negative Affect

With the growing concern about excessive Internet use and accompanying adverse psychosocial outcomes, unveiling the underlying mechanisms related to problematic Internet use has become an important topic to study. The present study examines the relationship between dispositional mindfulness and psychosocial well-being through problematic Internet use. An attempt has also been made to investigate whether negative affect and self-control are useful in explaining the relationship between dispositional mindfulness and problematic Internet use or not. The data was derived from a questionnaire survey of 246 postgraduate management students from a leading business school (approximately 48% females) and structural equation modelling technique was used for data analysis. The results suggest that higher mindfulness is associated with lower problematic Internet use, and the relationship is partially mediated by negative affect and self-control. Problematic Internet use partially mediate the relationship between mindfulness and depression/loneliness (indicators of psychosocial well-being). The study outcomes may prove helpful in empirical understanding of previously unidentified mediating mechanisms through which mindfulness may impact problematic Internet use, which further influences psychosocial well-being. Limitations and future directions, as well as potential implications, are also discussed.

Mobile Phone Addiction, Phubbing, and Depression Among Men and Women: A Moderated Mediation Analysis

For several years, the number of studies on the links between excessive mobile phone use and mental health has been increasing. The aim of the study was to establish if there is a relationship between mobile phone addiction and depression in university students and if phubbing is a mediator of this relationship. The authors also tested if this mediation effect was moderated by loneliness and if the model of relationships between these variables was the same in women and in men. The participants were 402 university and college students from Ukraine, aged 17 to 31; 74% of them were women. The authors used the Adapted Mobile Phone Use Habits, the Phubbing Scale, the Center for Epidemiologic Studies Depression Scale, and the Loneliness Scale. The results of the study have shown that higher mobile phone addiction and higher phubbing is associated with a higher level of depressive moods, with phubbing functioning as a mediator of the relationship between mobile phone addiction and depression. A moderator of this mediation is loneliness, the moderation effect being asymmetrically dependent on gender: in men, high loneliness increases the mediating role of phubbing, which more markedly translates into depression, while in women the analyzed mediation effect becomes weaker with an increase in the sense of loneliness (phubbing correlates less strongly with depression).

Addictive use of smartphone, depression and anxiety among female undergraduates in Nigeria: a cross-sectional study

Purpose

This study examined the prevalence and relationship between addictive use of smartphones and symptoms of depression and anxiety among female undergraduates.

Design/methodology/approach

Standardized scales were used to measure the addictive use of smartphones, depression and anxiety among 398 female students (mean age 21.75 years, SD = 2.67) at two large higher institutions in southwest Nigeria and were opportunely sampled. Two hypotheses were tested using Spearman's rho and Mann–Whitney U tests.

Findings

The results showed that 1.01% of the respondents were probable smartphone addicts and 17.34% were at-risk, while 14.32% and 16.33% manifested symptoms of anxiety and moderate-to-severe depression, respectively. Depression (r = 0.24, p < 0.01) and anxiety (r = 0.21, p < 0.01) have significant relationship with addictive use of smartphone. Addictive/at-risk smartphone users significantly scored higher on symptoms of depression (average rank of 233.40) than normal smartphone users (average rank of 191.88); U = 9387.50; z = −2.81, p < 0.05; Also, addictive/at-risk smartphone users reported significantly higher level of anxiety (average rank of 229.27) than normal smartphone users (average rank of 192.81); U = 9689.00; z = −2.46, p < 0.05.

Research limitations/implications

Generalizing these results to a clinical setting and other at-risk demographic groups might prove difficult due to the respondents' condition of homogeneity.

Practical implications

The findings suggest that relationships exist between the addictive use of smartphones and symptoms of depression and anxiety among undergraduate students in southwest Nigeria. Clinicians should assess smartphone use in the management of depression and anxiety disorders.

Social implications

University administrators should target prevention and intervention strategies that would assist students to be taught positive ways of using their smartphones.

Originality/value

The study contributes to the body of knowledge by revealing relationships between smartphone addiction and mental health in an African sample.

Cell Phone Use Habits Among the Spanish Population: Contribution of Applications to Problematic Use

Mobile phone abuse may be associated with health problems as well as with interferences in daily life. However, beyond the mobile as a device, the contributions of specific utilities and applications to the problematic mobile phone use remains to be analyzed. To address this important question we conducted 1,126 online interviews in Spain with participants aged 16 to 65 who are representative of the general population. The aim of the study was to analyze the patterns and differences of cell phone use based on habitual use, abuse, and problematic use, considering the most frequently used utilities and applications. Additional variables used were personal perception of cell phones, intensity of use, and participant's lifestyle with regard to entertainment and the maintenance of healthy habits. Further, we aimed to analyze difference between problematic and non-problematic mobile phone users in the utilization of applications, controlling for additional variables such as age, gender, educational level, consumption of tobacco and alcohol and illegal drugs. Results show that problematic use is consistent with the self-perception of abuse and is related to internet browsing, social media, music, and mobile games; particular applications of interest include Facebook, music applications, and Twitter. Furthermore, among problematic users, a pattern of interference with other activities or inappropriate use in certain contexts is observed, with a differential pattern of entertainment and abandonment of healthy habits. Finally, two binary logistic regression analyses demonstrated that beyond the cell phones themselves, specific utilities and applications such as browsing, chatting, or downloading and listening to music contribute to the differences between problematic and non-problematic users. Specifically, the use of Facebook, Twitter, and music applications have the greatest power to discriminate between the two types of users.

Smartphone addiction in students: A qualitative examination of the components model of addiction using face-to-face interviews

BACKGROUND AND AIMS

Smartphone use has increased markedly over the past decade and recent research has demonstrated that a small minority of users experience problematic consequences, which in extreme cases have been contextualized as an addiction. To date, most research have been quantitative and survey-based. This study qualitatively examined the components model of addiction for both "addicted" and "non-addicted" users.

METHODS

A screening tool comprising 10 dichotomous items was administered to 40 college students. Of these, six addicted and six non-addicted participants were identified on the basis of their score on the screening tool and were asked to participate in a semi-structured interview. The interview questions were based on the components model of addiction comprising six domains (i.e., salience, withdrawal, conflict, relapse and reinstatement, tolerance, and mood modification). Directed content analysis was used to analyze the transcribed data and subthemes as well as emerging themes for the study as a whole were established.

RESULTS

There was some evidence of demarcation between smartphone addicts on the dimensions of salience, tolerance, withdrawal, and conflict. Mood modification was not much different in either group, and no participant reported relapse.

CONCLUSIONS

The non-addicted group had much greater control over their smartphone usage than the addicted group on four (of six) aforementioned dimensions of behavioral addiction. Consequently, the main findings of this study provided good support for the components model of behavioral addiction.
