Investigating Parental Factors for Adolescent Problematic Gaming and Social Media Use - A Cross-sectional and Longitudinal Approach.

PURPOSE: Increasing concern has been raised on the addictive potential of digital games and socialmedia platforms, especially in adolescent users. Hence, investigating the etiology of problematic gaming (PG) and problematic social-media use (PSMU) is of great scientific and clinical interest. Parental factors have not been sufficiently addressed yet. Therefore, this study aims to investigate the predictive values of parental demographic, psychological, parenting, and role model factors for adolescent PG/PSMU. METHODS: In a representative parent-child (10-17 years) sample parental factors and adolescent PG/PSMU were assessed cross-sectionally (Ndyads = 1221) and longitudinally (Ndyads = 659) using online-questionnaires at two measurement points 14 months apart. Parental factors included parental media-use patterns, sociodemographic aspects, (digital) emotion regulation, stress perception, (digital) parental self-efficacy, and media rules. Best subset linear regression models were estimated to identify parental factors with greatest predictive values. These were included in prospective linear regression analyses. RESULTS: At the cross-sectional level, 18% of model variance predicting PG and 24% predicting PSMU could be explained by parental media-use patterns, media rules, and (digital) parental self-efficacy after controlling for adolescent age. Longitudinally, 33% of variance in the PG model and 34% of variance of the PSMU model could be explained by parental media-use patterns and parental self-efficacy after controlling for adolescent age and baseline PG/PSMU. DISCUSSION: This study is the first to differentially investigate parental factors in the context of adolescent PG/PSMU in a prospective representative parent-child study. Aspects of digital parental role modeling and parenting could be identified as promising anchors for prevention and treatment.

Prevalence of substance use disorders and associations with mindfulness, impulsive personality traits and psychopathological symptoms in a representative sample of adolescents in Germany.

Adolescence is a critical phase for the development of substance use disorders (SUDs). For Europe and Germany, there are limited data on problematic substance use from representative youth samples. Trait mindfulness is relevant in buffering against substance use-related problems and associated deficits in self-regulatory control. The objective of this study is to estimate 12-month prevalence rates for SUDs in a representative sample of adolescents in Germany and to examine associations with mindfulness and related factors such as stress, impulsivity, sensation seeking and symptoms of psychopathology. A sample of 4001 adolescents aged 12-18 years from Germany was surveyed based on DSM-IV diagnostic criteria for SUDs. Logistic regression analyses were used to examine associations with mindfulness-related variables. Criteria of at least one of the assessed SUDs were endorsed by 11.2% of the adolescents. Alcohol use disorders had the highest prevalence rate (10.1%) followed by cannabis use disorders (2.6%). For both substances, the criteria for abuse were met about twice as often as those for dependence. The prevalence of cigarette dependence was 1.7%, while the prevalence for e-cigarette dependence was only 0.1%. Prevalence rates were higher for male youth and increasing with age. SUD prevalence was also related to mindfulness, impulsivity and sensation seeking and externalizing symptoms of psychopathology. The statistically significant associations varied across different SUDs. SUDs appear highly prevalent among German adolescents. The results have public health implications with regard to treatment needs and prevention measures in the youth population in Germany.

Fear Without Context: Acute Stress Modulates the Balance of Cue-Dependent and Contextual Fear Learning.

During a threatening encounter, people can learn to associate the aversive event with a discrete preceding cue or with the context in which the event took place, corresponding to cue-dependent and context-dependent fear conditioning, respectively. Which of these forms of fear learning prevails has critical implications for fear-related psychopathology. We tested here whether acute stress may modulate the balance of cue-dependent and contextual fear learning. Participants (N = 72) underwent a stress or control manipulation 30 min before they completed a fear-learning task in a virtual environment that allowed both cued and contextual fear learning. Results showed equally strong cue- and context-dependent fear conditioning in the control group. Stress, however, abolished contextual fear learning, which was directly correlated with the activity of the stress hormone cortisol, and made cue-dependent fear more resistant to extinction. These results are the first to show that stress favors cue-dependent over contextual fear learning.
