The aim of the study was to assess the prevalence of online exposure to pornography in European adolescents and its relationship to sociodemographic and psychopathological correlates. A cross-sectional school-based survey of 10,930 adolescents (5211 males/5719 females), aged 14–17 years old (mean age 15.8 ± 0.7) was carried out in six European countries (Greece, Spain, Poland, Romania, the Netherlands, and Iceland). Anonymous self-completed questionnaires covered exposure to pornography, internet use and dysfunctional internet behavior, and psychopathological syndromes (measured by Achenbach’s Youth Self-Report). The prevalence of any online exposure to pornography was 59% overall and 24% for exposure at least once a week. The likelihood of online exposure to pornography was greater in male adolescents, heavier internet users, and those who displayed dysfunctional internet behavior. Country-specific analyses confirmed that the gender effect existed in every country, although its strength varied, from an odds ratio of 1.88 in Poland to 14.9 in Greece. Online exposure to pornography was shown to be associated with externalizing problem scale scores, especially rule-breaking and aggressive behavior, but also associated with higher scores in competences, namely activities and social competence. Exposure to pornography is ubiquitous, more relevant to boys, and is associated with both positive qualities/competences and externalizing behavioral problems.

Bullying is a universal problem which continues to be a serious threat to physical and emotional health of children and adolescents. This article highlights the prevalence, the common characteristics of bullies and victims, as well as the short- and long-term impact of bullying involvement. Key areas highlighted include the efficacy of bullying prevention programs, which can help health care providers to assess and provide interventions to children and adolescents affected by bullying.

Exposure-based cognitive-behavior therapy (EBCBT) is the treatment of choice for panic disorder (PD). However, little is known about early treatment processes that facilitate retention in treatment and positive outcomes of PD treatment. We studied the development of early treatment process with semi-structured individual in-depth interviews with 12 patients with PD, conducted post session 3. Grounded theory was used to analyze the transcripts. The development of early treatment process was captured by four thematic categories: approaching the problem, easing in and opening up, building trust and bonding, and making sense of panic. The developmental scheme culminated to the core category: Jointly Engaging in PD Therapy versus Awaiting Relief, capturing early engagement or disengagement from PD therapy respectively. The emergent core category was cross-validated against distal treatment outcome. Emergent processes can be replicated and incorporated in early treatment procedures of EBCBT for PD. Clinical practice recommendations are discussed.

Objectives: This study explored perceptions, experiences, and outcomes associated with the choice of insulin therapies among pediatric patients with type 1 diabetes mellitus (T1D). Methods: This study included 20 adolescents (8 male and 12 female) with T1D, with a mean age of 15.05 ± 0.91 years, a mean diabetes duration of 5.19 ± 1.2 years, and a mean most recent HbA1c of 7.03 ± 0.16%. Ten of the participants were using an insulin pump (n = 10) and another 10 had either refused (n = 7) or discontinued (n = 3) insulin pump therapy. A qualitative inductive method was employed, using in-depth individual interviews. The interview material was transcribed verbatim and grounded theory was used to analyze the verbal material. Results: Four main thematic categories were identified from the narrations that captured both common and divergent perceptions of insulin pump users versus non-users: (1) adjusting to the lifelong diagnosis, (2) exposing diabetes versus hiding it, (3) becoming autonomous and integrating insulin pump therapy into daily life, and (4) worrying over the pump. The third theme, capturing autonomy and integration, surfaced as the core thematic category of this study. Conclusions: This grounded theory study revealed that, by using insulin pump therapy, adolescent T1D patients can enhance their autonomy and facilitate the integration of insulin treatment into their life. This study identified processes that inform diabetes education and contribute to ameliorating gaps in the uptake and maintenance of pump therapy in pediatric care.
