Prevalence of pathological internet use among adolescents in Europe: demographic and social factors

Abstract: Aims To investigate the prevalence of pathological internet use (PIU) and maladaptive internet use (MIU) among adolescents in 11 European countries in relation to demographic, social factors and internet accessibility. Design Cross-sectional survey. Setting The 7th Framework European Union (EU) funded project, Saving and Empowering Young Lives in Europe (SEYLE), is a randomized controlled trial (RCT) evaluating interventions for risk behavioursamongadolescentsinAustria,Estonia,France,Germany,Hungary,Ireland,Israel,Italy,Romania,Slovenia andSpain,withSwedenservingasthecoordinatingcentre.Participants Atotalof 11 956adolescents(female/male: 6731/5225; mean age: 14.9 0.89) recruited from randomly selected schools within the 11 study sites. Measurements Internet users were classified by gender into three categories: adaptive, maladaptive and pathologi- cal, based on their score in the Young Diagnostic Questionnaire for Internet Addiction (YDQ). Findings The overall prevalence of PIU was 4.4%; it was higher among males than females (5.2% versus 3.8%) and differed between countries (c 2 = 309.98; d.f. = 20; P < 0.001). PIU correlated significantly with mean hours online and male gender. Thehighest-rankedonlineactivitieswerewatchingvideos,frequentingchatroomsandsocialnetworking;significantly higherratesof playingsingle-usergameswerefoundinmalesandsocialnetworkinginfemales.Livinginmetropolitan areas was associated with PIU. Students not living with a biological parent, low parental involvement and parental unemployment showed the highest relative risks of both MIU and PIU. Conclusions Across a range of countries in Europe, using the Young Diagnostic Questionnaire for Internet Addiction yields a prevalence of 'pathological internet use' of 4.4% among adolescents, but varies by country and gender; adolescents lacking emotional and psychological support are at highest risk.

The Association between Pathological Internet Use and Comorbid Psychopathology: A Systematic Review.

Abstract: Background: Pathological Internet use (PIU) has been conceptualized as an impulse-control disorder that shares characteristics with behavioral addiction. Research

Maternal depressive symptoms in the postnatal period are associated with long-term impairment of mother-child bonding.

Abstract: BACKGROUND: Postnatal Depression has demonstrated long-term consequences on child cognitive and emotional development, however, the link between maternal and child pathology has not been clearly identified. OBJECTIVE: This study examined whether maternal bonding to the infant and young child is impaired by maternal depressive symptoms. METHODS: 101 mothers of newborn infants were recruited from local obstetric units and examined for psychopathology using Symptom Checklist, the Edinburgh Postnatal Depression Scale (EPDS) and the Postpartum Bonding Questionnaire at two weeks, six weeks, four months and fourteen months postpartum. RESULTS: Maternal depressive symptoms at 2 weeks, 6 weeks and four months postnatally but not at fourteen months of infant's age were found to be strongly associated with lower quality of maternal bonding to the infant and child from two weeks until fourteen months of postnatal age. Even mild and unrecognized maternal depressive symptoms had a significant impact on maternal bonding, if they occurred during the first four months of life. CONCLUSIONS: This gives reason for increased concern for mother-infant dyads in the first few months after birth that could be regarded as a highly sensitive period for the development of the mother-child relationship. The findings warrant further studies and inspire the development of preventive programs focussing on infant and early childhood mental health by emphasizing protection and support during the first critical months.

Adolescent subthreshold-depression and anxiety: psychopathology, functional impairment and increased suicide risk

Abstract: Background: Subthreshold-depression and anxiety have been associated with significant impairments in adults. This study investigates the characteristics of adolescent subthreshold-depression and anxiety with a focus on suicidality, using both categorical and dimensional diagnostic models. Methods: Data were drawn from the Saving and Empowering Young Lives in Europe (SEYLE) study, comprising 12,395 adolescents from 11 countries. Based on self-report, including Beck Depression Inventory-II (BDI-II), Zung Self-Rating Anxiety Scale (SAS), Strengths and Difficulties Questionnaire (SDQ) and Paykel Suicide Scale (PSS) were administered to students. Based on BDI-II, adolescents were divided into three groups: nondepressed, subthreshold-depressed and depressed; based on the SAS, they were divided into nonanxiety, subthreshold-anxiety and anxiety groups. Analyses of Covariance were conducted on SDQ scores to explore psychopathology of the defined groups. Logistic regression analyses were conducted to explore the relationships between functional impairments, suicidality and subthreshold and full syndromes. Results: Thirty-two percent of the adolescents were subthreshold-anxious and 5.8% anxious, 29.2% subthreshold-depressed and 10.5% depressed, with high comorbidity. Mean scores of SDQ of subthreshold-depressed/anxious were significantly higher than the mean scores of the nondepressed/nonanxious groups and significantly lower than those of the depressed/anxious groups. Both subthreshold and threshold-anxiety and depression were related to functional impairment and suicidality. Conclusions: Subthreshold-depression and subthreshold-anxiety are associated with an increased burden of disease and suicide risk. These results highlight the importance of early identification of adolescent subthreshold-depression and anxiety to minimize suicide. Incorporating these subthreshold disorders into a diagnosis could provide a bridge between categorical and dimensional diagnostic models. Keywords: Categorical diagnostic model, dimensional diagnostic model, subthreshold-depression, subthreshold-anxiety, adolescent, suicide, SEYLE.

Annual Research Review: A meta-analysis of the worldwide prevalence of mental disorders in children and adolescents

Abstract: Background The literature on the prevalence of mental disorders affecting children and adolescents has expanded significantly over the last three decades around the world. Despite the field having matured significantly, there has been no meta-analysis to calculate a worldwide-pooled prevalence and to empirically assess the sources of heterogeneity of estimates. Methods We conducted a systematic review of the literature searching in PubMed, PsycINFO, and EMBASE for prevalence studies of mental disorders investigating probabilistic community samples of children and adolescents with standardized assessments methods that derive diagnoses according to the DSM or ICD. Meta-analytical techniques were used to estimate the prevalence rates of any mental disorder and individual diagnostic groups. A meta-regression analysis was performed to estimate the effect of population and sample characteristics, study methods, assessment procedures, and case definition in determining the heterogeneity of estimates. Results We included 41 studies conducted in 27 countries from every world region. The worldwide-pooled prevalence of mental disorders was 13.4% (CI 95% 11.3–15.9). The worldwide prevalence of any anxiety disorder was 6.5% (CI 95% 4.7–9.1), any depressive disorder was 2.6% (CI 95% 1.7–3.9), attention-deficit hyperactivity disorder was 3.4% (CI 95% 2.6–4.5), and any disruptive disorder was 5.7% (CI 95% 4.0–8.1). Significant heterogeneity was detected for all pooled estimates. The multivariate metaregression analyses indicated that sample representativeness, sample frame, and diagnostic interview were significant moderators of prevalence estimates. Estimates did not vary as a function of geographic location of studies and year of data collection. The multivariate model explained 88.89% of prevalence heterogeneity, but residual heterogeneity was still significant. Additional meta-analysis detected significant pooled difference in prevalence rates according to requirement of funcional impairment for the diagnosis of mental disorders. Conclusions Our findings suggest that mental disorders affect a significant number of children and adolescents worldwide. The pooled prevalence estimates and the identification of sources of heterogeneity have important implications to service, training, and research planning around the world.
