Legislation is a powerful tool for facilitating mental healthcare. Gender is an important social determinant of physical and mental health. Many jurisdictions are in the process of revising their mental health law, to align with human rights commitments. Consideration of gender in these revisions could enhance the mental healthcare received by women, transgender and non-binary individuals.

This paper examines gender-based provisions in mental health law published in English.

Countries that use English as an official language were identified. Jurisdictions in these countries with stand-alone mental health laws were included. Legislation was reviewed for gender-specific provisions.

Seventy-five countries were evaluated; 71 jurisdictions were included. Thirty-eight jurisdictions had 88 gender-specific provisions. These addressed ten key areas, including: general gender-based protections, female representation on boards and review panels, protections during searching and restraint, gender separated facilities, protections in relation to parenting, fertility, sterilisation and termination. Fiji, Ghana, India, and the Australian jurisdictions had the highest number of gender-specific laws. However, gender-specific provisions are highly heterogeneous and are drafted from a cisnormative perspective and fail to adequately address the specific needs of individuals outside of that framework.

Gender-specific provisions can enhance the protections afforded by mental health law. However, as legislation can be a blunt instrument, careful consideration must be given to potential unintended consequences. During revisions of mental health law consideration should be given to gender-specific provisions and legislation must be inclusive of individuals identifying as transgender, non-binary and other genders.

Bipolar disorder (BD) is a recurrent chronic disorder characterised by fluctuations in mood and energy disposition. Diseases could lead to degenerative alterations in brain structures such as corpus callosum (CC). Studies demonstrated that abnormalities in CC are associated with BD symptoms. The present study aims to analyse the CC of the patients with statistical shape analysis (SSA) and compare the findings with healthy controls.

Forty-one BD patients and 41 healthy individuals in similar age groups, which included 23 female and 18 male subjects, participated in the study. CC was marked with landmarks on the mid-sagittal images of each individual. The mean ‘Procrustes’ point was calculated, and shape deformations were analysed with thin-plate spline analysis.

Significant differences were observed in the shape of CC between the two groups, where maximum CC deformation was observed in posterior region marks in BD patients. There was no significant difference between the CC area of the BD patients and controls.

CC analysis conducted with SSA revealed significant differences between patients and healthy controls. The study findings emphasised the abnormal distribution of white matter in CC and the variable subregional nature of CC in BD patients. This study may enable the development of more targeted and effective treatment strategies by taking into account biological factors and understanding the differences in the brain regions of individuals with BD.

Investigations of computerised cognitive training (CCT) show heterogeneous results in slowing age-related cognitive decline.

To comprehensively evaluate the effectiveness of serious games-based CCT, integrating control conditions, neurophysiological and blood-based biomarkers, and subjective measures.

In this bi-centric randomised controlled trial with parallel groups, 160 participants (mean age 71.3 years) with cognitive impairment ranging from subjective decline to mild cognitive impairment, were pseudo-randomised to three arms: an intervention group receiving CCT immediately, an active control (watching documentaries) and a waitlist condition, which both started the CCT intervention after the control period. Both active arms entailed a 3-month intervention period comprising a total of 60 at-home sessions (five per week) and weekly on-site group meetings. In the intervention group, this was followed by additional 6 months of CCT, with monthly booster sessions to assess long-term training effects. Behavioural and subjective changes were assessed in 3-month intervals. Biological effects were measured by amyloid blood markers and magnetic resonance imaging obtained before and after training.

Adherence to the training protocol was consistently high across groups and time points (4.87 sessions per week). Domain-specific cognitive scores showed no significant interaction between groups and time points. Significant cognitive and subjective improvements were observed after long-term training. Voxel-based morphometry revealed no significant changes in grey matter volume following CCT, nor did amyloid levels moderate its effectiveness.

Our study demonstrates no benefits of 3 months of CCT on cognitive or biological outcomes. However, positive effects were observed subjectively and after long-term CCT, warranting the inclusion of CCT in multicomponent interventions.

There is considerable evidence that waiting list (WL) control groups overestimate the effect sizes of psychotherapies for depression. It is not clear, however, what are the exact causes for this overestimation. We decided to conduct a meta-analytic study to compare trials on psychotherapy for depression with a WL control group against trials with a care-as-usual (CAU) control group.

We used an existing meta-analytic database of randomized trials comparing psychological treatments of adult depression with control groups and selected trials using a WL or a CAU control group. We used subgroup and meta-regression analyses to examine differences in effect sizes between WL and CAU controlled trials.

We included 333 randomized controlled trials (472 comparisons; total number participants: 41,480), 141 with a WL and 195 with a CAU control group (3 included both). We found several significant differences between WL and CAU controlled trials (in type of therapy examined, treatment format, recency, target group, recruitment strategy, number of treatment arms and number of depression outcome measures). The overall effect size indicating the difference between treatment and control at post-test for all comparisons was g = 0.77 (95% confidence interval [CI]: 0.71; 0.84) with high heterogeneity (I2 = 84; 95% CI: 82; 85). A highly significant difference was observed between studies with a CAU control group (g = 0.63; 95% CI: 0.55; 0.71; I2 = 85; 95% CI: 83; 86) and studies with a WL (g = 0.95; 95% CI: 0.85; 1.04; I2 = 80; 95% CI: 78; 82; p for difference < 0.001). This difference remained significant in all sensitivity analyses, including a meta-regression analysis in which we adjusted for all differences in characteristics of studies with a WL versus CAU control group. We also found that pre-post effect sizes in WL control conditions (g = 0.37; 95% CI: 0.28; 0.46) were significantly smaller than change within CAU conditions (g = 0.64; 95% CI: 0.50; 0.78). We found few indications that pre-post effect sizes within therapy conditions differed between WL and CAU controlled trials.

WL control conditions considerably overestimate the effect sizes of psychological treatments, compared to trials using CAU control conditions. This overestimation is probably caused by a smaller improvement within the WL condition compared to the improvement in the CAU condition. WL control conditions should be avoided in randomized trials examining psychological treatments of adult depression.

Between 2008 and 2019, we reported positive change relating to mental health stigma and discrimination among the adult population of England, supporting the effectiveness of the Time to Change campaign.

Using data from the Attitudes to Mental Illness survey (2008/2009 to 2023), we investigated the extent to which positive changes in stigma were sustained by 2023, 2 years after the programme's end in 2021.

We used regression analyses to evaluate trends in outcomes. Measures were of stigma-related knowledge (Mental Health Knowledge Schedule (MAKS)), attitudes (Community Attitudes toward the Mentally Ill scale (CAMI)) and desire for social distance (Reported and Intended Behaviour Scale (RIBS)). We also examined willingness to interact with people based on vignettes of depression and schizophrenia, and attitudes toward workplace discrimination, using data from the British Social Attitudes Survey for comparison.

CAMI scores improved between 2008 and 2023 (s.d. 0.24, 95% CI 0.16–0.31), but decreased since 2019 (P = 0.015). After improvements between 2009 and 2019, 2023 MAKS and RIBS scores no longer differed from 2009 scores, indicating decreases in stigma-related knowledge (MAKS scores declined 7.8%; P < 0.001) and willingness to interact (RIBS scores declined by 10.2%; P < 0.001) since 2019. Conversely, comparison with British Social Attitudes Survey data indicated that willingness to interact with people with depression and schizophrenia increased gradually between 2007, 2015 and 2023, and attitudes to workplace discrimination also improved.

The lasting positive changes reflect support for non-discrimination and willingness to interact with someone after a sense of familiarity is evoked. Besides the end of Time to Change, interpretations for declines in other outcomes include the COVID-19 pandemic and economic stress.

Growing evidence indicates an association between disordered eating and a range of mental health problems, including anxiety, depression and emotional dysregulation.

This study aimed to explore whether reducing risk factors for eating disorders, such as body dissatisfaction and low self-esteem, through school-based programmes can enhance adolescent mental health.

We searched PubMed, PsycINFO, EMBASE and Web of Science from the date of inception to 15 October 2023. Data were synthesised by using a systematic narrative synthesis framework, and formal assessments were conducted to assess the quality of the included studies.

After title/abstract screening and full-text assessment, 13 articles met the pre-specified inclusion criteria, comprising a total of 14 studies (n = 5853). Notably, three studies encompassed multiple programmes, leading to the identification of 17 eating disorder prevention programmes. Among these programmes, seven (41%) employed dissonance-based approaches. Topics covered in the programmes included psychoeducation, body acceptance, sociocultural issues, nutrition and physical activities, self-esteem and stress coping. Ten (59%) of the programmes were effective in improving adolescent mental health. Six of the 14 studies (43%) did not specify follow-up time, and quality assessments found the majority to be of either high (five studies, 36%) or fair (eight studies, 57%) quality.

The findings from the ten effective programmes consistently support the use of body acceptance strategies in improving the mental health of adolescent students. Brief interventions delivered by trained, non-licensed facilitators appear good for the sustainable implementation of in-school psychological services to support well-being among adolescents.

Child and adolescent mental health service in-patient beds are unevenly spread throughout England. Where demand outstrips bed availability, young people may be admitted at-distance or to adult psychiatric wards. The COVID-19 pandemic added pressures to already overstretched services. Understanding experiences during this period is vital to inform strategies for future emergencies.

To investigate the impact of the COVID-19 pandemic on admissions to local, at-distance or adult psychiatric units, from the perspectives of young people, parents/carers and healthcare professionals.

Multi-methods data were collected from February 2021 to September 2022, as part of the Far Away from Home research programme. A 13-month national surveillance study collected information about admissions to general adolescent units >50 miles from home, out-of-region or to adult psychiatric units. Free-text data from respondents (n = 51) were analysed using content analysis. Interviews with young people (n = 30), parents/carers (n = 21) and healthcare professionals (n = 68) were analysed using thematic analysis.

Restrictions during the COVID-19 pandemic affected young people's contact with others; the requirement to self-isolate on admission and following overnight leave felt distressing, and visiting was limited. This disincentivised overnight leave, leading to some discharges being delayed and others feeling rushed and high risk. The COVID-19 pandemic also accelerated the introduction of virtual meetings, enabling community teams and families to be more involved in therapies, meetings and decision-making.

Restrictions imposed during the COVID-19 pandemic were often negatively perceived. However, the increased use of technology was felt to be positive, widening inclusion and mitigating some negative effects of distance on admissions.

Despite mounting evidence linking neurological diseases with climate change, the link between autism spectrum disorder (ASD) and global warming has yet to be explored.

To examine the relationship between the incidence of ASD and global warming from 1990 to 2019 and estimate the trajectory of ASD incidence from 2020 to 2100 globally.

We extracted meteorological data from TerraClimate between 1990 and 2019. To estimate the association between global ASD incidence and temperature variation, we adopted a two-stage analysis strategy using a generalised additive regression model. Additionally, we projected future ASD incidence under four representative shared socioeconomic pathways (SSPs: 126, 245, 370 and 585) by bootstrapping.

Between 1990 and 2019, the global mean incidence of ASD in children under 5 years old was 96.9 per 100 000. The incidence was higher in males (147.5) than in females (46.3). A 1.0 °C increase in the temperature variation was associated with a 3.0% increased risk of ASD incidence. The association was stronger in boys and children living in a low/low-middle sociodemographic index region, as well as in low-latitude areas. According to the SSP585 scenario, by 2100, the children living in regions between 10 and 20° latitude, particularly in Africa, will experience a 68.6% increase in ASD incidence if the association remains. However, the SSP126 scenario is expected to mitigate this increase, with a less than 10% increase in incidence across all latitudes.

Our study highlights the association between climate change and ASD incidence worldwide. Prospective studies are warranted to confirm the association.

Higher specialist trainees (HSTs) in psychiatry in Ireland were recruited to complete a 21-item online questionnaire anonymously. Questions were designed to establish the research experience of HSTs in various years of training, identify perceived barriers to participation and generate potential strategies to overcome these barriers.

Of 165 HSTs surveyed, 50 (30%) responded. Most respondents (58%) were in the second or third year of HST. Most (72%) were training in general adult psychiatry. Themes that emerged from analysis of the qualitative data were ‘collaborative research culture’, ‘guidance’, ‘choice’ and ‘access to resources’. Participants felt they needed more structured guidance and regular supervision, and expressed a desire for more networking and collaboration.

The need for a supportive, collaborative research culture within psychiatry was predominant among responses. Structured research programmes and access to resources may facilitate a more positive research culture and should be considered as part of the training curriculum.

Existing self-rated depression measurement tools possess a range of psychometric drawbacks, spanning a range of validity and reliability constructs. The gold standard self-rated depression scales contain several variable items that are often non-specific, require respondents to have a certain level of language understanding and limited scoring options resulting in low sensitivity. The Maudsley three-item visual analogue scale (M3VAS) was developed to address these challenges.

This study aimed to translate the M3VAS into Chinese and test its reliability and validity.

First, both M3VAS scales (assessing current severity and change in severity) were translated according to a standardised protocol to finalise the Chinese version. Reliability and validity were then examined among 550 young people with moderate to severe depression (patient health questionnaire-9 (PHQ-9) score ≥15) in a cross-sectional opportunistic questionnaire survey.

The content validity of each item (six items, across both scales) ranged from 0.83 to 1.00. Exploratory factor analysis denoted a total of two common factors, with a variance contribution rate of 64.34%. The total score correlated positively with the PHQ-9 total score (r = 0.241, P < 0.01). The Chinese version of the M3VAS had good reliability and validity values, and the confirmatory factor model fit well.

The psychometric properties of the Chinese version of the M3VAS suggest that this scale can feasibly evaluate depression among young people in China.

Despite the frequent co-occurrence of depression and diabetes, gender differences in their relationship remain unclear.

This exploratory study examined if gender modifies the association between depressive symptoms, prediabetes and diabetes with cognitive-affective and somatic depressive symptom clusters.

Cross-sectional analyses were conducted on 29 619 participants from the 2007–2018 National Health and Nutrition Examination Survey. Depressive symptoms were measured by the nine-item Patient Health Questionnaire. Multiple logistic regression was used to analyse the relationship between depressive symptoms and diabetes. Multiple linear regression was used to analyse the relationship between depressive symptom clusters and diabetes.

The odds of having depressive symptoms were greater in those with diabetes compared to those without. Similarly, total symptom cluster scores were higher in participants with diabetes. Statistically significant diabetes–gender interactions were found in the cognitive-affective symptom cluster model. Mean cognitive-affective symptom scores were higher for females with diabetes (coefficient = 0.23, CI: 0.10, 0.36, P = 0.001) than males with diabetes (coefficient = −0.05, CI: −0.16, 0.07, P = 0.434) when compared to the non-diabetic groups.

Diabetes was associated with higher cognitive-affective symptom scores in females than in males. Future studies should examine gender differences in causal pathways and how diabetic states interact with gender and influence symptom profiles.
