This study examined whether Internet addiction (IA) and digital competence (DC) mediated the association between digital technology use and mental health problems in adolescents before and during the COVID-19 pandemic, when digital device use increased dramatically. Repeated cross-sectional data from a 3-year cross-cohort study adopting stratified random sampling were analyzed. In 2019, 569 adolescents (female = 312) from 14 secondary schools completed a DC assessment and an online survey on their digital technology use, IA, and mental health. In 2021, 775 adolescents (female = 397) from 11 of those 14 schools completed both instruments. Results showed that adolescents in 2021 spent more time using digital devices, were more digitally competent, and reported more mental health problems than adolescents in 2019. The prevalence of IA was 8 percent in 2019 and 12.4 percent in 2021. In both years, more frequent digital technology use predicted a higher risk of IA, which was associated with more mental health problems (indirect = 0.08, < 0.001 for 2019 and = 0.05, < 0.001 for 2021). In addition, in 2021, DC was positively associated with digital technology use and negatively with IA, which indirectly related to fewer mental health problems (indirect = -0.01, = 0.03). In conclusion, DC is a protective factor alleviating the positive associations of digital technology use and IA with mental health problems in adolescents when the ecological context requires high levels of digital device use.

Department of Medical Psychology, Air Force Medical University, Xi'an, China.
Purpose: The purpose of this study was to use the advanced technique of Network Intervention Analysis (NIA) to investigate the trajectory of symptom change associated with the effects of self-control training on youth university students' chronic ego depletion aftereffects.
Methods: The nine nodes of chronic ego depletion aftereffects and integrated self-control training were taken as nodes in the network and analyzed using NIA. Networks were computed at the baseline, at the end of treatment, at 1-, 3-, 6-, 9- and 12-month follow up.

Background: Given the increasing recognition of the value of greater integration of physical and mental health services for children and young people, we aimed to evaluate preferences among parents for the characteristics associated with integrated health service provision for two conditions (eating disorders, functional symptom disorders).
Methods: Two discrete choice experiments (DCEs) were conducted, using electronic surveys. Participants were adult parents of children and young people.

Background: Over one-third of the global stillbirth burden occurs in countries affected by conflict or a humanitarian crisis, including Afghanistan. Stillbirth rates in Afghanistan remained high in 2021 at over 26 per 1000 births. Stillbirths have devastating physical, psycho-social and economic impacts on women, families and healthcare providers.

Background: Breast cancer is the most diagnosed cancer in women worldwide and carries a considerable psychosocial burden. Interventions based on Acceptance and Commitment Therapy (ACT) and compassion-based approaches show promise in improving adjustment and quality of life in people with cancer. The Mind programme is an integrative ACT and compassion-based intervention tailored for women with breast cancer, which aims to prepare women for survivorship by promoting psychological flexibility and self-compassion.

BMC Psychiatry

Department of Behavioural Science and Health, University College London, London, 1-19 Torrington Place, WC1E 7HB, UK.
Background: Smoking rates in the UK have declined steadily over the past decades, masking considerable inequalities, as little change has been observed among people with a mental health condition. This trial sought to assess the feasibility and acceptability of supplying an electronic cigarette (e-cigarette) starter kit for smoking cessation as an adjunct to usual care for smoking cessation, to smokers with a mental health condition treated in the community, to inform a future effectiveness trial.
Methods: This randomised controlled feasibility trial, conducted March-December 2022, compared the intervention (e-cigarette starter kit with a corresponding information leaflet and demonstration with Very Brief Advice) with a 'usual care' control at 1-month follow-up.
