Challenges and opportunities in the mental health landscape of the Maldives.

This article outlines the history of mental health service delivery with contemporary challenges and opportunities in the Maldives. Mental health has been traditionally the domain of faith healers in the Maldives. This changed gradually with the availability of treatments as well as increased public awareness, and mental health is now recognized as an emerging health issue. The current challenges for the mental health system include governance issues, access to services, human resource limitations, poor prevention efforts, and lack of research. These challenges may be overcome by focussing on opportunities through strengthened governance, intersectoral collaboration, mainstream integration of mental health, and local research.

Characteristics of Clinical Supervision for Mental Health Nurses: A Survey Study Using the MCSS-26.

To describe the characteristics and perceived effectiveness of clinical supervision mental health nurses are receiving and further explore any statistical correlations between the perceived effectiveness and satisfaction with the supervisee, supervisor and supervision characteristics. A cross-sectional survey. An online survey was distributed to nurses working in public mental health services in Victoria, Australia. A universal recruitment approach was used, and 422 nurses participated in the survey. Of these, 220 nurses who are participating in clinical supervision were eligible for the MCSS-26 survey. A licensed MCSS-26 questionnaire. Mental health nurses in the studied environment were likely to receive individual supervision from a senior mental health nurse, with the most common frequency being monthly for 31-60 min, and half receiving it within their workplace location. Half of the participants chose their own supervisor. Our findings indicate that nurses who engage in clinical supervision outside of their immediate workplace and receive individual supervision from a nurse of the same grade perceive higher effectiveness. We also found that clinical nurses may find it most difficult to engage in effective clinical supervision due to time constraints. This study uniquely contributes to the current clinical supervision literature by reporting the uptake and detailed characteristics of supervision, a facet often overlooked in existing research. This study reported the characteristics of the supervision, supervisor and the supervisee that are associated with the effective clinical supervision. These insights can lead to tailored implementation strategies that consider the specific roles and settings of nurses. CROSS (Sharma etal. 2021). No patient or public contribution.

The Underuse of Clozapine and Long-Acting Injectable Antipsychotics.

Schizophrenia is among the most devastating and costly human diseases. The public face of the failure to appropriately treat schizophrenia includes approximately 100,000 homeless individuals with schizophrenia and related psychoses and 200,000 incarcerated individuals with similar diagnoses. Clozapine and long-acting injectable antipsychotics are among the most effective treatments, but both are markedly underused. The following organizations should take responsibility for fixing this problem: National Institute of Mental Health, Patient-Centered Outcomes Research Institute, Substance Abuse and Mental Health Services Administration, Centers for Medicare and Medicaid Services, U.S. Food and Drug Administration, American Psychiatric Association, and patient and family advocacy groups.

Barriers and enablers to a coordinated MHPSS response in Lebanon: A case study of the MHPSS Taskforce

During humanitarian crises, under-resourced and overstretched health systems may not be able to fully meet mental health and psychosocial support (MHPSS) needs of affected populations, including refugees, internally displaced persons and host communities. Health system governance is vital to humanitarian health response, but there has been little research on this, particularly for MHPSS. We present a case study of a national MHPSS coordination mechanism (the MHPSS Taskforce) in Lebanon, a country which has experienced multiple crises and hosts over 2 million refugees. The aim was to explore the barriers and enablers facing the MHPSS Taskforce in responding to the needs of displaced and host populations in Lebanon. Interviews were conducted with 34 key stakeholders, including Taskforce members, representatives from non-governmental organisations, United Nations agencies, and government Ministries. Our findings show that the positioning of MHPSS within the humanitarian cluster system acts as a barrier to mounting an effective response, with the MHPSS Taskforce sometimes siloed rather than integrated across clusters. Coordination within the Taskforce was reported to be effective in some respects, but limited by a lack of clarity about its decision-making processes, affiliation, mandate, and inclusion of regional perspectives and key groups such as mental health services users in Lebanon. While the technical capacity of the Taskforce is strong, limited funding and staffing were seen to impact its capacity to effectively oversee the MHPSS response in Lebanon. Key recommendations include: the need for stronger mechanisms and operating procedures for interagency and inter-sectoral collaboration on MHPSS within the humanitarian cluster system; greater clarity on the role of the Taskforce and key Taskforce actors, streamlined reporting channels and greater inclusion of diverse perspectives, particularly mental health service users; and greater financial and human resources within coordination mechanisms to support the national MHPSS response in Lebanon.

Medication Adherence and Functioning in Individuals With Bipolar Disorder Type I.

To determine the correlation between medication adherence and functioning in individuals with bipolar disorder (BD) and the predictors of functionality. This cross-sectional and correlational study was conducted with 145 individuals with BD type I. Data were collected using a Patient Information Form, the Medication Adherence Rating Scale, and Functioning Assessment Short Test. Findings showed that most participants did not take medication as prescribed. Medication adherence was negatively correlated with functionality. Predictors of functionality were years of treatment, number of hospitalizations, working status, medication adherence, family history of mental illness, and history of suicide. Medication nonadherence is a fundamental problem for individuals with BD. Nursing interventions to increase functionality and medication adherence among this at-risk group should be planned and implemented.

Medication Adherence and Its Relationship With Quality of Life and Functionality in Individuals With Bipolar Disorder: A Cross-Sectional Correlational Study.

The current cross-sectional correlational study aimed to determine the relationship of medication adherence with functionality and quality of life in individuals with bipolar disorder (BD). The research was conducted with 141 individuals with BD followed as outpatients. Data were collected using an information form, Morisky Medication Adherence Scale (MMAS), Quality of Life in Bipolar Disorder Scale (QoL.BD), and Bipolar Disorder Functioning Questionnaire (BDFQ). A significant positive correlation was found between participants' MMAS total score and QoL.BD (p < 0.001) and BDFQ (p < 0.05) scores. A significant positive correlation was also found between QoL.BD and BDFQ scores (p < 0.001). Medication compliance positively affects quality of life and social functionality in individuals with BD. Thus, interventions to increase medication adherence are recommended. [Journal of Psychosocial Nursing and Mental Health Services, xx(x), xx-xx.].

Fear of Death and Sleep Quality in the Aftermath of an Earthquake.

To examine fear of death and disruption in sleep patterns in individuals who have experienced an earthquake. A descriptive and relationship-oriented study was performed with 322 individuals who experienced the February 6, 2023, earthquake in Turkey. Data were collected between February 20 and May 15, 2023. A personal information form, the Pittsburgh Sleep Quality Index (PSQI), and Death Anxiety Scale (DAS) were used for data collection. Participants' mean DAS score was 7.96 (SD = 1.05), and mean PSQI score was 8.74 (SD = 4.06). Statistically significant relationships were found between sex, marital status, and mean DAS score, and these variables accounted for 11.7% of the total variance. Similarly, statistically significant relationships were found among economic status, relationship to person trapped under the rubble, financial loss from the earthquake, and mean PSQI score, accounting for 11.3% of the total variance. Women and married people had greater fear of death, and those with good economic status, whose family members were buried under rubble, and who experienced financial loss as a result of the earthquake had lower sleep quality. The earthquake led to moderate fear of death and poor sleep quality among participants. Findings highlight the need for targeted support for vulnerable groups following disasters.

Breaking the Silence: Addressing Domestic Abuse in Mental Health Settings-Identification, Screening, and Responding.

Individuals experiencing domestic abuse (DA) struggle to disclose victimization, but as frequent users of mental health services, this is a pivotal setting for identification and addressing DA. This systematic review of 20 studies investigates DA identification, screening, and responses within mental health settings. Three databases were searched using these inclusion criteria: adults aged 18 and older accessing mental health services, samples comprising mental health professionals (or combination). No geographical restrictions were applied. All studies were peer-reviewed and published in English between January 2000 and December 2023. Studies had to incorporate screening for DA between (ex-)partners and/or response to disclosure within mental health settings. The findings revealed considerable variation in DA screening methods from direct screening tools to retrospective analyses of patient files. Professionals report barriers in identifying DA, including uncertainty about their role, time constraints, and the importance of building trust with service users. Nonetheless, many highlight the importance of routinely asking about DA. A small number of interventions have been effective in enhancing professionals' readiness to address DA, but it remains unclear what format of training is most effective. Service users report feelings of shame and fear of not being believed when disclosing DA, but are aided by therapeutic engagement and enhanced professional awareness. There is a lack of diverse inclusion in the research. In summary, there is considerable scope to develop good practice to support mental health professionals' ability to identify and respond to DA across assessment tool and training, but also in understanding what facilitates service users to disclose.

Effect of Obstructive Sleep Disorder Treatment on Posttraumatic Stress Disorder Symptoms: A Literature Review.

To explore whether continuous positive airway pressure (CPAP) adherence among adult patients with obstructive sleep apnea (OSA) and posttraumatic stress disorder (PTSD) affects the PTSD Checklist (PCL), a validated tool that measures severity of PTSD symptoms. Studies focusing on PTSD and OSA were searched in PubMed and CINAHL databases. Inclusion and exclusion criteria were applied, decreasing the article yield to nine. All articles chosen focused on the adult population and were conducted in North America. The literature review yielded eight observational cohort studies and one descriptive study. Seven studies were conducted with Veterans and all studies used the PCL tool. Three themes were identified: (a) Trauma and OSA, (b) OSA and PTSD Symptoms, and (c) CPAP Therapy and PTSD Symptoms. An area of further study is assessing how CPAP adherence might affect improvement in PTSD symptoms and how adherence can be improved. OSA is correlated with more severe PTSD symptoms, but CPAP use is associated with improvement in PTSD symptoms. The literature reviewed found PCL scores improved up to 10 points within 3 months of CPAP use. These findings highlight the importance of collaboration between mental health and sleep medicine professionals and opportunity for further study in this area.

Obsessive-compulsive disorder with compulsive exercise leading to intensive care treatment in an adolescent male: a case report.

Obsessive-compulsive disorder (OCD) and eating disorders (ED) are compulsive disorders with overlapping symptoms. However, weight loss and over-exercise causing secondary medical complications are rarely seen in OCD. We report the case of a 15-year-old male who presented with atypical symptoms of OCD leading to severe medical compromise. Covid-19 related team sport restrictions led to compulsive exercise associated with intrusive thoughts. The onset of stress fractures limited exercise ability,prompting compensatory food restriction. Bradycardia, hypothermia and hypoglycaemia resulted from severe malnourishment and weight loss in the context of OCD. His weight was 85.8% of ideal body weight on admission, reflective of a weight 10-15 kg lower than his premorbid weight. During admission, he developed exercise-induced rhabdomyolysis with significantly elevated creatinine kinase and required intensive care unit treatment. Psychotropic medication included lamotrigine, olanzapine and high dose fluoxetine alongside cognitive-behavioural therapy. Medical stabilisation and weight restoration allowed discharge to an outpatient Child and Adolescent Mental Health Service. This atypical case of OCD highlights the potentially life-threatening risks associated with excessive exercise and malnutrition. This paper highlights the complexities of treatment in a patient who cannot adhere to bed rest and the differential diagnoses of anorexia nervosa, orthorexia nervosa and exercise addiction.

Age-Related Variation in Ecological Resources Among Veterans Seeking Treatment Related to Military Sexual Trauma.

Approximately 16% of Veterans experience military sexual trauma (MST), defined as sexual assault or harassment experienced during military service. Veterans across life stages may possess differing resources and face unique stressors that impact their ability to engage in mental health treatment or require additional liaison to services. The present study sought to characterize age-related differences in the socioecological contexts of Veterans seeking mental health treatment following MST in the domains of economic sufficiency, housing, spiritual coping, supportive relationships, and interpersonal violence. From 2009 to 2019, Veterans (N = 640) seeking mental health services following exposure to MST attended evaluation and treatment planning sessions at a Midwestern Veterans Health Administration posttraumatic stress disorder specialty clinic. Veterans completed semistructured interviews that included surveys and diagnostic screenings to assess psychosocial needs and resources. ANOVA and ordinal regressions were used to evaluate potential disparities in socioecological resources by age. No age-related differences in economic sufficiency and stable housing emerged, though most Veterans (57%) endorsed financial difficulties. Veterans who endorsed spiritual beliefs were significantly older than those who did not. Veterans who reported having a support system were significantly younger than Veterans who denied having a support system. Less than half (46%) of Veteran reported having peer relationships. Veterans who endorsed frequent interaction with their peers were significantly older than those who did not. Veterans who reported past-year exposure to interpersonal violence were significantly younger. Greater clarity about age-related differences in the socioecological contexts of Veterans can support clinicians in providing responsive mental health treatment and connecting Veterans to additional Veterans Health Administration resources following MST.

Mapping the pathway and support offered to children with an intellectual disability referred to specialist mental health services in the UK.

This survey of 66 specialist mental health services aimed to provide an up-to-date description of pathways of care and interventions available to children with an intellectual disability referred for behaviours that challenge or with suspected mental health problems. Overall, 24% of services made contact with a family at referral stage, whereas 29% contacted families at least once during the waiting list phase. Only two in ten services offered any therapeutic input during the referral or waiting list stages. During the active caseload phase, services offered mostly psychoeducation (52-59%), followed by applied behaviour analytic approaches for behaviours that challenge (52%) and cognitive-behavioural therapy (41%). Thirty-six per cent of services had not offered any packaged or named intervention in the past 12 months. With increasing waiting times for specialist mental health support, services need to consider increasing the amount of contact and therapeutic input on offer throughout all stages of a child's journey with the service.

Hospitalization trends among immigrants and natives in an acute psychiatric service: a descriptive study from Italy

Acute psychiatric services are crucial for immigrants who face barriers in accessing outpatient mental healthcare due to socio-economic, cultural, and linguistic challenges. This study compared psychiatric hospitalization characteristics between immigrants and native Italians at the University of Foggia from 2004 to 2019. A total of 536 inpatients, equally divided between immigrants and natives, were analysed for sociodemographic and clinical variables. Findings revealed that immigrants were hospitalized through emergency departments for severe psychiatric disorders such as psychosis, while natives were more often admitted for mood disorders. Immigrants showed a higher incidence of substance abuse and suicidal attempts and a lower number of prior hospitalizations compared to natives, with higher incidence of first episodes of mental illness. Despite presenting with severe psychopathology, natives exhibited better clinical outcomes, longer hospitalizations and higher functioning improvements. We also found that natives received more psychotropic medications but experienced fewer adverse effects compared to immigrants. Differences in pharmacological treatments and hospital outcomes suggested that culturally tailored interventions could improve the effectiveness of psychiatric care for migrants. These findings emphasized the necessity for systemic changes in mental health services to address disparities and improve care for migrant populations.

Quantifying the experiences of Black and Dual Heritage young people in a forensic child and adolescent mental health service.

Young people from racialised backgrounds are overrepresented in justice services. This study explored differences in community support offered to young people from racialised groups referred to a forensic child and adolescent mental health service. We compared support offered to 427 young people, according to five ethnic groups. Over 20% of young people referred were Black (compared with 14% of the local population) and 15.8% were Dual White and Black Heritage (compared with 4% of the local population). Odds ratios showed that Black and Dual Heritage groups were more frequently involved with youth offending services (Black: 2.59, Dual Heritage: 2.88), gangs services (Black: 4.31, Dual Heritage: 7.13) and have a national referral mechanism (Black: 3.61, Dual Heritage: 4.01) than their White peers, but were less often in mainstream education compared with their Asian peers (Black: 0.26, Dual Heritage: 0.29). Black (odds ratio 0.35) and Dual Heritage (odds ratio 0.40) young people were less frequently diagnosed with a neurodevelopmental disorder than their White peers. Those from Black and Dual Heritage backgrounds were disproportionately disadvantaged.

A national evaluation of QbTest to support ADHD assessment: a real-world, mixed methods approach.

QbTest is a commercially available, computerised test of attention, impulsivity, and activity designed to assist with the diagnosis of attention deficit hyperactivity disorder (ADHD). Health Innovation East Midlands (formerly East Midlands AHSN), led the implementation of the QbTest on behalf of the 15 Health Innovation Networks across Child and Adolescent Mental Health services (CAMHS) and Paediatric sites in England between April 2020 and March 2023. We evaluate the impact of this programme on diagnostic assessment at participating sites. A mixed-methods approach was used including: case-note data collected on 10-30 cases per site pre and post QbTest implementation; interviews with healthcare staff working with QbTest; and surveys to explore perspectives of healthcare staff and patients/carers. Case-note data was descriptively analysed to compare time to diagnosis (number of appointments and days) pre/post QbTest implementation. Survey data was analysed descriptively. Qualitative interview data was explored using thematic analysis. Case-note data was provided by 20 sites across England. Comparison of mean values pre- and post-QbTest implementation identified a decrease of 0.37 (11.5%) in number of appointments to reach a diagnostic decision, a 55-day (12.5%) increase in days from initial referral to diagnosis, and a 12-day (10.3%) increase in days to reach a diagnostic decision. Exploratory analyses indicated greater benefit for Paediatric services over CAMHS, in terms of a decrease in days from referral to diagnosis and number of appointments to diagnosis. Interviews with healthcare staff (n=21) revealed that the QbTest was perceived to support a faster, more efficient diagnostic process. Survey data (n=65 healthcare staff, n=22 patients/carers) identified that the QbTest helped patients understand their symptoms and the diagnostic decision. Although some logistical issues (e.g., room requirements) and patient issues (e.g., sensory sensitivity) were identified, healthcare staff considered that QbTest was easily incorporated into the ADHD assessment pathway. The national implementation of QbTest in ADHD clinics resulted in a small reduction in the number of clinical appointments needed to reach a diagnostic decision, with greatest benefit demonstrated in Paediatric sites. Data were impacted by COVID-19 therefore, further evaluation is warranted.

Child maltreatment and insomnia symptoms among Chinese university students: the buffering role of self-efficacy.

Insomnia symptoms represent a significant public health concern, as it engenders substantial long-term health consequences. Considerable research has established the detrimental impacts of child maltreatment on sleep problems among university students. However, the role of self-efficacy in the association between childhood maltreatment and insomnia remains unclear. This study aimed to examine the associations between child maltreatment and insomnia symptoms among university students, and to investigate whether self-efficacy moderated the effects of child maltreatment on insomnia symptoms. A total of 2014 participants with random cluster sampling method were recruited from Jinan University in Guangzhou, China, from October 2022 to November 2022. Adjusting for covariates, the results of multiple logistic regression indicated that the participants with the experience of any type of child maltreatment (odds ratio [OR] 2.24, 95% confidence interval [CI] 1.63-3.07), childhood emotional abuse (OR 2.58, 95% CI 1.95-3.41), childhood emotional neglect (OR 1.16, 95% CI 0.87-1.54), childhood physical abuse (OR 2.15, 95% CI 1.60-2.8), childhood physical neglect (OR 2.19, 95% CI 1.64-2.92), childhood sexual abuse (OR 1.98, 95% CI 1.46-2.68) were more likely to report insomnia symptoms than those without. Individuals reporting one-two types and three-five types of child maltreatment were 1.81 times (95% CI 1.30-2.52) and 3.77 times (95% CI 2.58-5.50) more likely to report insomnia symptoms than those reporting zero types of child maltreatment, respectively. Furthermore, robust linear regression analysis revealed that self-efficacy moderated the associations between child maltreatment and insomnia symptoms (β = 0.007, 95% CI 0.004-0.010). These findings underscore the need for integrated mental health education, support services, and faculty training to address the impact of child maltreatment on insomnia symptoms among university students. Policy recommendations include advocating for comprehensive mental health services, incorporating self-efficacy initiatives, and fostering community engagement for a holistic approach to student well-being.

Debate: How much should nonspecialists be involved in mental health care for children and young people when resources are limited? Working with police forces to improve mental health crisis care for young people.

The last few years have seen a mental health crisis for children and young people in the UK, with more young people presenting to services at crisis point. Young people have reported that there is a general lack of support before reaching the point of crisis and police forces in the UK have seen a rise in callouts related to youth mental health problems. We provide an overview of the evidence for joint responses from police and mental health services and highlight the importance of including people with lived experience in the development of crisis services. Most of the available data relates to interventions for adults, with very few studies including children and young people. We outline a new study in the UK aiming to evaluate a joint response for young people experiencing a mental health crisis. Whilst resources for children and young people's crisis services remain limited, joint response models with police forces can help to provide much needed intervention.

What Determines Healthcare Workers to Seek Professional Psychological Support? A Cross-Sectional Study.

Although healthcare workers often experience significant mental health challenges, their willingness to seek professional psychological help remains relatively low. However, the factors associated with healthcare workers' psychological help-seeking remain unclear. This study aims to identify the determinants of professional psychological help-seeking intention among healthcare workers based on the theory of planned behaviour. Cross-sectional study. A questionnaire, incorporating demographic information and latent variable items, was developed and employed on 403 healthcare workers through online and offline surveys from December 2022 to January 2023 using convenience sampling. Structural equation modelling was applied to test the research hypotheses. The model explained 46.9% of the variance in help-seeking intention. Subjective norm had the strongest total association with help-seeking intention. Attitude towards help-seeking behaviour, subjective norm and perceived behavioural control were directly positively related to help-seeking intention. Moreover, self-stigma, public stigma, perceived barriers and perceived risk were indirectly associated with help-seeking intention mediated by attitude towards the behaviour and perceived behavioural control. Of the four constructs, public stigma showed the most significant indirect relation to behavioural intention. Healthcare workers' intention to seek psychological support is associated with multiple interacting factors, particularly subjective norm and public stigma. Targeted interventions addressing individual and systemic barriers are essential to create a supportive environment for healthcare workers to access mental health services. This study identified key barriers and facilitators to healthcare workers seeking psychological support, which can assist authorities in enhancing mental health services and implementing tailored intervention strategies, thereby promoting help-seeking behaviour among healthcare workers. Moreover, our research reinforces the applicability of the theory of planned behaviour in explaining healthcare workers' intention to seek professional psychological support. No patient or public contribution.

'I'm ruined': Young people's and their mothers' experiences of living with, and receiving a diagnosis of, borderline personality disorder: An interpretative phenomenological analysis.

The adolescent borderline personality disorder (BPD) diagnosis has been widely debated for many years. Strikingly, young people's experiences of both receiving a diagnosis of BPD, and of living with BPD, are largely under-explored. The current study seeks to address these gaps in the literature in a multi-perspectival design utilising young people-parent dyads. Young people (aged 16-18 years) with a diagnosis of BPD (n = 5) and their mothers (n = 5) were recruited from two NHS Community Mental Health Services in the West Midlands and participated in semi-structured interviews. Data were analysed using interpretative phenomenological analysis [IPA]. Analysis identified two superordinate themes with five subthemes: (1) The "ugly" reality of living with BPD (providing a stark insight into what it is like to live with the unpredictable nature of experiences labelled as BPD), and (2) The diagnosis that dare not speak its name (highlighting the complexities of how the diagnosis itself is experienced by participants as a symbol of personal and permanent defectiveness and danger). Findings highlight a clear commonality of experience centred around the intensity of the young people's emotional distress and the accompanying pressure on parents to keep young people safe, both of which services must strive to do more to contain. Ultimately, the costs of receiving a BPD diagnosis appear to outweigh the benefits, and this paper adds support to calls for change in respect to how we conceptualise difficulties labelled as BPD and how we communicate about these difficulties, in order to avoid causing harm.

Self-harm, suicidal ideation, depression and peer relationships in transgender and gender diverse adolescents accessing specialist mental health services.

There are an estimated 25 million transgender and gender diverse (TGD) individuals worldwide, with 1.2%-2.7% of this population being under the age of 18. Community studies describe increased rates of mental health difficulties such as depression, self-harm, suicidal ideation and difficulties with peer relationships for TGD youth over cisgender peers. However, comparatively little is known about the mental health symptomatology of TGD youth attending specialist mental health services (CAMHS) in the UK. This cross-sectional study explored data from 170 young people participating in the Beating Adolescent Self-Harm (BASH) trial. Baseline data about self-harm, depression, and impact on daily life was compared for those who identified as TGD (n = 18) with those who identified as cisgender (n = 152). In the transgender group, 18 (100%) scored ≥27 on the MFQ suggesting severe depression and had total scores on the SDQ impact scale of ≥3, in the very high range. In comparison in the cisgender group, 140 (92.1%) scored ≥27 on the MFQ and 103 (67.8%) had total scores on the SDQ impact scale of ≥3. The TGD group reported higher rates of self-harm, poorer peer relationships, less prosocial behaviour and greater interference with friendships and leisure activities and impact in the classroom. Both groups reported similar symptoms of depression. Whilst this exploratory study has limitations, these results suggest that TGD youth attending CAMHS may experience greater mental health problems than their cisgender peers.
