A team from the University of California (USA) has published an article questioning the scientific evidence supporting bans on social media for teenagers. Among other reasons, they argue that studies conducted to date on restricting social media use have focused on adults. Furthermore, as one of the authors points out in a press release, these restriction experiments "show weak, negligible, and mixed effects, with 40% of experimental studies reporting harmful effects (e.g., lower life satisfaction and increased loneliness) or no effect from social media restrictions." Some of the authors, whose article is published in Frontiers in Developmental Psychology, declare having ties to companies in the social media industry.

The American Psychiatric Association has unveiled the new features of the forthcoming Diagnostic and Statistical Manual of Mental Disorders (DSM) in five articles published in The American Journal of Psychiatry. Among the highlights are the proposed change of name — it will become the Diagnostic and Scientific Manual — and the intention for it to be more dynamic, incorporating biomarkers for diagnosis and integrating the socioeconomic, cultural and environmental determinants of health. According to the authors, the aim is to enable a more personalised and inclusive clinical practice, aligned with scientific rigour. The most recent update was published in 2022 with the DSM-5-TR, and specialists are currently unaware of the date of the next edition, as they reported during a briefing with journalists.

A study published in Scientific Reports concludes that adults who use Instagram very frequently overestimate their ‘addictive’ use, which complicates self-control and increases feelings of guilt. According to the research, excessive use, in most cases, is not an addiction but a habit. The study was conducted on more than 1,000 Americans and suggests that the fact that many think they have an ‘addiction’ may be related to the media's frequent use of this term when talking about social media. 

From 2014 to 2023, one in six people in the world suffered from loneliness, according to a World Health Organisation report, which outlines the causes of this phenomenon and its multiple impacts: on physical and mental health and mortality, as well as on work and the economy. The report estimates that loneliness is linked to more than 871,000 deaths per year and highlights a higher incidence among young people and in low- and middle-income countries.

Unmarried people - whether single, divorced/separated or widowed - have a higher risk of having depressive symptoms than married people, says an international study. The paper, published in Nature Human Behaviour, includes data from more than 100,000 adults in China, Indonesia, Ireland, Korea, Mexico, the UK, the USA and the UK.

People who have a parent, sibling, or step-sibling with major depression have a higher risk of major depression themselves, according to research based on data from 2.9 million people in Denmark. This risk increases with the number of affected relatives and when exposure to depression occurs in childhood and adolescence, but does not vary by sex or kinship, says the study published in JAMA Psychiatry.
