ABSTRACT

BACKGROUND: Internet Gaming Disorder (IGD) has been associated with symptoms of Digital Eye Strain (DES) and poor academic performance among adolescent students. The purpose of this study is to assess whether a student's achievement of a specific academic goal within a short period of time can be directly predicted by symptoms of IGD and DES. METHODS: This is a cross-sectional survey of 140 high school graduates who received an examination of visual acuity as a pre-requisite for entering the written admission examinations of law enforcement and military academies. The students completed the Digital Eye Strain Questionnaire (DESQ) and the Ten-Item Internet Gaming Disorder Test (IGDT-10) and stated their own evaluation of their chances for success. They were contacted following their admission examinations, and their success or failure to be admitted was recorded. RESULTS: The students with IGD symptomatology were more likely to present with symptoms of DES. They were also more pessimistic about their chances of success in the subsequent written admission examinations; none succeeded, while the rest of the students recorded an expected rate of success. A combination of IGD and complaints related to the prolonged fixation of the upper body in a specific viewing position was the best predictor variable set for future success in admission examinations. CONCLUSIONS: IGD is associated with a failure to achieve academic success. Combining a factor for physical discomfort during prolonged sessions of gaming with the typical criteria for IGD may expand the predictive validity of the construct of gaming disorder.

ABSTRACT

Digital Eye Strain (DES) is a clinical syndrome manifested with visual disturbances and/or ophthalmic dysfunction related to the usage of screen-enabled digital equipment. This term is gradually replacing the older term computer vision syndrome (CVS) that focused on the same symptoms found on personal computer users. DES is encountered more frequently during the past years due to the explosive increase in the usage of digital devices and subsequent increase in time in front of any screens. It presents with a series of atypical symptoms and signs stemming from asthenopia, dry eye syndrome, preexisting untreated vision issues and poor screen ergonomics. This review summarizes research data to date to determine whether the concept of DES has been conclusively defined and demarcated as a separate entity and if sufficient guidance is offered on professionals and the lay public. The maturity of the field, grouping of symptoms, examination techniques, treatment and prevention modalities are summarily presented.

ABSTRACT

SIGNIFICANCE: The use of screen-enabled handheld devices has increased exponentially during the last few years among the older adults. Up until now, a general suggestion for preventing symptoms of digital eye strain with large screen use was to address any existing refractive error, including presbyopia. It is unclear whether this advice is of consequence in the case of smaller handheld devices. PURPOSE: The aim of this study was to examine whether correcting presbyopia ameliorates the negative effect on digital screen use, examining handheld devices where these issues are expected to be more acute with presbyopic individuals. METHODS: This is a cross-sectional study of 120 consecutive participants who had received correction for presbyopia during the past month and returned for a routine follow-up examination. The participants filled in a demographics questionnaire, questions on time spent online and using devices with digital screens, data on their eye complaints, and the validated Digital Eye Strain Questionnaire (DESQ). RESULTS: The DESQ factor scores and total score correlated with the near addition ( P < .001). Higher DESQ scores were associated (by order of magnitude) with higher near addition and a lower amount of time spent using a handheld screen-enabled device ( P < .001) while controlling for age and type of corrective lenses. CONCLUSIONS: Results indicate that older adults are at an additional disadvantage while using handheld screen-enabled devices compared with younger adults: they are more likely to be presbyopes and need higher near addition, yet increasing near addition does not guarantee greater comfort in the use of smartphones but rather increase the likelihood of experiencing digital eye strain symptoms.

ABSTRACT

PURPOSE: Patients with age-related macular degeneration (ARMD) are required to follow a treatment protocol that requires regular follow-ups. The COVID-19 pandemic has created an additional burden for patients with ARMD under treatment with anti-vascular endothelial growth factor (anti-VEGF) injections, since patients face a congestion of the health system and closing of the outpatient services. This study examines the impact of the uncertainty regarding patients' treatment on their sense of well-being. METHODS: This is a longitudinal cohort study of eighty patients who were followed during the year following the outbreak of the COVID pandemic. Patients reported their sense of well-being with the WHO-5 questionnaire and their perception and fears for the impact of the pandemic on their ongoing ARMD treatment. RESULTS: There was a significant drop in mental well-being during the pandemic that paralleled the self-reported impact of the pandemic on ARMD treatment. Patients who reported a higher impact of COVID-19 on their treatment had experienced a higher drop in mental wellbeing compared to those who hadn't, with female gender being an additional risk factor. Objective measurements of visual acuity did not factor in the drop of sense of well-being. CONCLUSIONS: The high initial level of uncertainty regarding ARMD patients' long-term course was further exacerbated when exposed to additional uncertainties during the pandemic regarding their standard of care. Planning ahead for continuation of services and close contact with patients during similar health emergencies is of paramount importance.

ABSTRACT

Recent results from a small number of clinical studies have resulted in the suggestion that the process of blocking the transmission of shorter-wavelength light ('blue light' with a wave length of 450 nm to 470 nm) may have a beneficial role in the treatment of bipolar disorder. This critical review will appraise the quality of evidence so far as to these claims, assess the neurobiology that could be implicated in the underlying processes while introducing a common set of research criteria for the field.

ABSTRACT

INTRODUCTION: 'Digital eye strain' (DES) is a clinical syndrome with eyesight symptoms related to continuous engagement in front of a screen-enabled digital device. With use of these devices constantly on the rise, the related symptoms have become prominent, even in younger ages. This study describes the process of validating the Digital Eye Strain Questionnaire (DESQ), a thirteen-item self-report scale in a yes-no format designed to offer a measure of complaints related to digital eye strain syndrome (DES). METHODS: The validation process included 150 outpatients with no long-standing eye disease who were examined for various eye complaints and 50 outpatients who were diagnosed with gaming addiction according to WHO ICD-11 clinical criteria. All participants filled in a demographics questionnaire, the DESQ, the Computer Vision Syndrome Questionnaire (CVS-Q) and the Problematic Internet Use Questionnaire-9 (PIUQ-9). RESULTS: Principal component analysis of categorical variables confirmed the proposed three-factor DES structure with a total of 61.02% of explained variance and Cronbach's alpha equal to.94. Concurrent validity was assessed by comparing the results of the DESQ to the CVS-Q while convergent validity was assessed by examining correlations of the DESQ with results from the PIUQ-9 questionnaire. In all cases the DESQ demonstrated excellent reliability and validity. CONCLUSIONS: Results indicate that the DESQ questionnaire can be employed to reliably measure the symptomatology of digital eye strain in clinical populations who present either with eye issues or with excessive use of the gaming and screen-enabled devices in general.

ABSTRACT

Objectives: The nine-item Problematic Internet Use Questionnaire (PIUQ-9) is a brief self-report screening instrument for problematic internet use. The main objective of the present study was to explore the psychometric properties of the PIUQ-9 among nine different language-based samples of European internet users (Italian, German, French, Polish, Turkish, Hungarian, English, and Greek). Methods: The total sample comprised 5,593 internet users (38.1% men), aged between 18 and 87 years (M = 25.81; SD = 8.61). Via online recruitment, participants completed the PIUQ-9, the Brief Symptom Inventory (BSI) and items about time spent online. Results: Confirmatory factor analysis demonstrated that the bifactor model with one general factor (i.e., general problem) and two-specific factors (i.e., obsession and neglect + control disorder) yielded acceptable or good fit indices in all subsamples except for one. The common variance index in the bifactor model indicated that the general problem factor explained from 57.0 to 76.5% of common variance, which supports the presence of a strong global factor. According to the multiple indicators multiple causes (MIMIC) model, psychiatric symptoms had a moderate-to-strong direct effect on the general problem factor in all subsamples, ranging from ß = 0.28 to ß = 0.52 supporting the construct validity of the scale. Furthermore, in a majority of the subsamples, time spent online during the weekend had considerably higher effect sizes on the general problem factor than time spent online during weekdays. Conclusion: The present study highlights the appropriate psychometric properties of the PIUQ-9 across a number of European languages and cultures.

ABSTRACT

Research on adolescence gambling over the past twenty years has revealed significant incidence and prevalence rates and highlighted the possible negative effects on an adolescent's well-being. Several risk and protective factors have also been identified. Over the course of the past few years, technological advances have heralded the advent of new avenues for gambling as well as new opportunities to gamble without any direct monetary exchange. This review article examines those established trends as well as the new issues that we are faced with, in order to accurately portray the current challenges in research, prevention, and treatment.

ABSTRACT

This study assessed the results from the parallel application of two alternate personality models, the Zuckerman-Kuhlman trait model and Bond's Defense Styles, in a sample of 268 Greek medical students (172 women, M age = 22.0 yr., SD = 1.1; 95 men, M age = 22.3 yr., SD = 1.2) in relation to psychopathological symptoms, so as to clarify whether this practice yielded accurate results while avoiding shared variance. Data from both models are cross-checked with canonical correlation analysis to validate whether there was significant conceptual overlap between them that would mean that their parallel use is an ineffective research practice. Following this analysis, factors from both models are utilized to predict variance in sample psychopathology, so as to compare their relative usefulness. Results indicated that the two models did not share a significant amount of variance, while a combination of personality aspects from both models, including Impulsive Sensation-Seeking, Neuroticism-Anxiety, Aggression-Hostility, and Sociability traits and Maladaptive Action, Image Distorting, and Adaptive Action defense styles, predicted high variance in psychopathology symptoms.

ABSTRACT

The increasing use of computers and the internet - especially among young people - apart from its positive effects, sometimes leads to excessive and pathological use. The present study examined the relationship among the excessive use of the internet by university students, the alexithymia components and sociodemographic factors associated with internet users and their online activities. 515 university students from the University of Thessaly participated in the study. Participants anonymously completed: a) the Internet Addiction Test (IAT), b) the Toronto Alexithymia Test (TAS 20) and c) a questionnaire covering various aspects of internet use and demographic characteristics of internet users. Excessive use of the internet among Greek university students was studied within a multi-factorial context and was associated with the alexithymia and demographic factors in nonlinear correlations, forming thus a personalized emotional and demographic profile of the excessive internet users.

ABSTRACT

BACKGROUND: The introduction of new technological media worldwide has had a number of unfortunate side effects for some adolescents, including cases of bullying others through the new media (cyberbullying) and over-involvement to the point of addiction. We examine the epidemiology of cyberbullying in a Greek setting, compare it with earlier data, determine the impact of any related psychosocial factors, and propose measures to combat the phenomenon. METHODS: A cross-sectional study of the entire adolescent high-school student population of the island of Kos examined the relationship between their experiences of Internet cyberbullying and respective parental characteristics, including aspects of psychological bonding and online security measures. The sample consisted of 2017 students (51.8% boys, 48.2% girls). Comparisons are made with results obtained from an earlier survey in the same setting, 2 years earlier. RESULTS: There was a significant rise in reported experiences of Internet cyberbullying over the 2-year period. Security practices exercised by parents had a protective role with regards to whether a child had been cyberbullied, yet failed to prevent the perpetration of online victimization. A regression model indicated that impulsive use of the Internet and related online activities were predictive of whether an adolescent victimized others online. CONCLUSION: Cyberbullying frequency with regards to both victims and victimizers was high and associated with online impulsiveness, pointing to the possible existence of some commonalities. Further research is necessary to ascertain common underlying psychological factors and neurobiology.

ABSTRACT

BACKGROUND: Affective temperaments may represent heritable subclinical manifestations of mood disorders. The concept of ego defense mechanisms also has provided a model for the comprehension of mood psychopathology. The relationships between affective temperaments, defense styles and depressive symptoms remain unknown. METHODS: We obtained data from a subsample of the Brazilian Internet Study on Temperament and Psychopathology (BRAINSTEP). Socio-demographic information was collected and participants completed the Affective and Emotional Temperament Composite Scale (AFECTS), the defense style questionnaire (DSQ-40) and the Symptom Checklist-90-Revised (SCL-90-R). RESULTS: Among 9937 participants (4472 male; 45%), individuals with hyperthymic or euthymic temperaments were more likely to present a mature defense style, whereas an immature defensive style was predominantly observed in individuals with cyclothymic, volatile, depressive, dysphoric, euphoric and disinhibited temperaments. Higher immature and lower mature defense style scores were independently associated with depressive symptoms. Participants with either euthymic or hyperthymic temperaments were less likely to endorse depressive symptoms. Euthymic and hyperthymic temperaments moderated the correlations of mature/immature defenses with depressive symptoms. LIMITATIONS: The data was collected from a convenience web-based sample. The study was cross-sectional. CONCLUSIONS: Affective temperaments are associated with distinct defense styles. These two personality theories provide distinct but interacting views for comprehension of depressive psychopathology.

ABSTRACT

We present results from a cross-sectional study of the entire adolescent student population aged 12-19 of the island of Kos and their parents, on the relationship between their Internet gambling and respective parental practices, including aspects of psychological bonding and online security measures. The sample consisted of 2,017 students (51.8% boys, 48.2% girls). Our results indicate that gender, parenting practices as perceived by the adolescents and distinct patterns of adolescent Internet activities are among the best predictor variables for Internet gambling. Security practices exercised by the parents failed to make an impact on the extent of Internet gambling, demonstrating the need for specific measures to tackle this phenomenon since the provision of simple education on the dangers of the Internet is not sufficient to this regard.

ABSTRACT

This study examines the nature of the relationship between psychosocial factors and insomnia complaints in an adolescent non-clinical population. It is a cross-sectional study of a stratified sample of 2,195 Greek adolescent high-school students. Subjects were given the Athens insomnia scale, the Symptom Checklist scale (SCL-90-R) and a questionnaire concerning demographic characteristics. None of the subjects had received help for insomnia complaints or other overt psychopathology. Adolescents classified as suffering from insomnia presented higher levels of general psychopathology. Age, tobacco and alcohol use, self-reported patterns of communication in the family, perceived economic status and school performance were identified as correlates of the insomnia complaints. A significant number of adolescents fail to receive appropriate treatment for insomnia. Psychosocial correlates are important factors to consider when faced with insomnia complaints in this age group. More research is needed in important timelines in the developmental history of a young adult.
