Although self-harm and sleep problems are major public health problems in adolescence, detailed epidemiological assessment is essential to understand the nature of this relationship.

To conduct a detailed assessment of the relationship between sleep and self-harm in adolescence.

A large population-based study in Norway surveyed 10 220 adolescents aged 16–19 years on mental health, including a comprehensive assessment of sleep and self-harm.

Adolescents with sleep problems were significantly more likely to report self-harm than those without sleep problems. Insomnia, short sleep duration, long sleep onset latency, wake after sleep on set as well as large differences between weekdays versus weekends, yielded higher odds of self-harm consistent with a dose–response relationship. Depressive symptoms accounted for some, but not all, of this association.

The findings highlight a strong relationship between sleep problems and self-harm. Interventions to reduce adolescent self-harm ought to incorporate sleep problems as a treatment target.

The long-term outcome of never-treated patients with schizophrenia is unclear.

To compare the 14-year outcomes of never-treated and treated patients with schizophrenia and to establish predictors for never being treated.

All participants with schizophrenia (n = 510) in Xinjin, Chengdu, China were identified in an epidemiological investigation of 123 572 people and followed up from 1994 to 2008.

The results showed that there were 30.6%, 25.0% and 20.4% of patients who received no antipsychotic medication in 1994, 2004 and 2008 respectively. Compared with treated patients, those who were never treated in 2008 were significantly older, had significantly fewer family members, had higher rates of homelessness, death from other causes, being unmarried, living alone, being without a caregiver and poor family attitudes. Partial and complete remission in treated patients (57.3%) was significantly higher than that in the never-treated group (29.8%). Predictors of being in the never-treated group in 2008 encompassed baseline never-treated status, being without a caregiver and poor mental health status in 1994.

Many patients with schizophrenia still do not receive antipsychotic medication in rural areas of China. The 14-year follow-up showed that outcomes for the untreated group were worse. Community-based mental healthcare, health insurance and family intervention are crucial for earlier diagnosis, treatment and rehabilitation in the community.

It is unknown whether prodromal services improve outcomes in those who go on to develop psychosis, and whether these patients are demographically different from the overall first-episode population.

To compare sociodemographic features, duration of untreated psychosis, hospital admission and frequency of compulsory treatment in the first year after the onset of psychosis in patients who present to prodromal services with patients who did not present to services until the first episode of psychosis.

We compared two groups of patients with first-episode psychosis: one who made transition after presenting in the prodromal phase and the other who had presented with a first episode.

The patients who had presented before the first episode were more likely to be employed and less likely to belong to an ethnic minority group. They had a shorter duration of untreated psychosis, and were less likely to have been admitted to hospital and to have required compulsory treatment.

Patients who develop psychosis after being engaged in the prodromal phase have a better short-term clinical outcome than patients who do not present until the first episode. Patients who present during first episodes may be more likely to have sociodemographic features associated with relatively poor outcomes.

Empathy is a basic human ability, and patients with schizophrenia show dysfunctional empathic abilities on the behavioural and neural level.

These dysfunctions may precede the onset of illness; thus, it seems mandatory to examine the empathic abilities in individuals at clinical high risk for psychosis.

Using functional magnetic resonance imaging, we measured 15 individuals at clinical high risk of psychosis (CHR group) and compared their empathy performance with 15 healthy volunteers and 15 patients with schizophrenia.

Behavioural data analysis indicated no significant deficit in the CHR group. Functional data analysis revealed hyperactivation in a frontotemporoparietal network including the amygdala in the CHR group compared with the other two groups.

Despite normal behavioural performance, the CHR group activated the neural empathy network differently and specifically showed hyperactivation in regions critical for emotion processing. This could suggest a compensatory mechanism reflecting emotional hypersensitivity or dysfunctional emotion regulation. Further investigations should clarify the role of these neural alterations for development and exacerbation of psychosis.

Prescribing of antidepressants varies widely between European countries despite no evidence of difference in the prevalence of affective disorders.

To investigate associations between the use of antidepressants, country-level spending on healthcare and country-level attitudes towards mental health problems.

We used Eurobarometer 2010, a large general population survey from 27 European countries, to measure antidepressant use and regularity of use. We then analysed the associations with country-level spending on healthcare and country-level attitudes towards mental health problems.

Higher country spending on healthcare was strongly associated with regular use of antidepressants. Beliefs that mentally ill people are ‘dangerous' were associated with higher use, and beliefs that they ‘never recover’ or ‘have themselves to blame’ were associated with lower and less regular use of antidepressants.

Contextual factors, such as healthcare spending and public attitudes towards mental illness, may partly explain variations in antidepressant use and regular use of these medications.

There is little information on lung function and respiratory diseases in people with psychosis.

To compare the respiratory health of people with psychosis with that of the general population.

In a nationally representative sample of 8028 adult Finns, lung function was measured by spirometry. Information on respiratory diseases and symptoms was collected. Smoking was quantified with serum cotinine levels. Psychotic disorders were diagnosed utilising the Structured Clinical Interview for DSM-IV (SCID-I) and medical records.

Participants with schizophrenia and other non-affective psychoses had significantly lower lung function values compared with the general population, and the association remained significant for schizophrenia after adjustment for smoking and other potential confounders. Schizophrenia was associated with increased odds of pneumonia (odds ratio (OR) = 4.9), chronic obstructive pulmonary disease (COPD, OR = 4.2) and chronic bronchitis (OR = 3.8); and with high cotinine levels.

Schizophrenia is associated with impaired lung function and increased risk for pneumonia, COPD and chronic bronchitis.

Accurate detection of persons in need of mental healthcare is crucial to reduce the treatment gap between psychiatric burden and service use in low- and middle-income (LAMI) countries.

To evaluate the accuracy of a community-based proactive case-finding strategy (Community Informant Detection Tool, CIDT), involving pictorial vignettes, designed to initiate pathways for mental health treatment in primary care settings.

Community informants using the CIDT identified screen positive (n = 110) and negative persons (n = 85). Participants were then administered the Composite International Diagnostic Interview (CIDI).

The CIDT has a positive predictive value of 0.64 (0.68 for adults only) and a negative predictive value of 0.93 (0.91 for adults only).

The CIDT has promising detection properties for psychiatric caseness. Further research should investigate its potential to increase demand for, and access to, mental health services.

Little is currently known about the presence and impact of personality disorder in adolescents who self-harm.

To evaluate personality disorder in repeated self-harm in adolescence and its impact on self-harm psychopathology and adaptation outcomes over 1 year.

A clinical referral sample (n = 366) of adolescents presenting with repeated self-harm aged 12–17 years, as part of a randomised controlled trial (Assessment of Treatment in Suicidal Teenagers study, ASSIST). Personality disorder was assessed using the Structured Clinical Interview for DSM-IV Axis II (SCID-II). One-year outcomes included frequency and severity of repeat self-harm, self-reported suicidality, mood and functional impairment.

About 60% of the referred adolescents showed one or more forms of personality disorder. Personality disorder was associated with significantly greater severity of self-harm, overall psychopathology and impairment. There was a complex association with treatment adherence. Personality disorder predicted worse 1-year outcomes in relation to self-harm frequency and severity, as well as impairment, suicidality and depressive symptoms.

Personality disorder can be reliably measured in adolescence and showed high prevalence in this clinical self-harm sample. Controlling for other variables, it showed a strong independent association with self-harm severity at referral and predicted adherence to treatment and clinical outcomes (independent of treatment) over 1 year. Consideration of personality disorder diagnosis is indicated in the assessment and management of adolescents who repeatedly self-harm.

Early intervention services (EIS) comprise low-stigma, youth-friendly mental health teams for young people undergoing first-episode psychosis (FEP). Engaging with the family of the young person is central to EIS policy and practice.

By analysing carers' accounts of their daily lives and affective challenges during a relative's FEP against the background of wider research into EIS, this paper explores relationships between carers' experiences and EIS.

Semi-structured longitudinal interviews with 80 carers of young people with FEP treated through English EIS.

Our data suggest that EIS successfully aid carers to support their relatives, particularly through the provision of knowledge about psychosis and medications. However, paradoxical ramifications of these user-focused engagements also emerge; they risk leaving carers' emotions unacknowledged and compounding an existing lack of help-seeking.

By focusing on EIS's engagements with carers, this paper draws attention to an urgent broader question: as a continuing emphasis on care outside the clinic space places family members at the heart of the care of those with severe mental illness, we ask: who can, and should, support carers, and in what ways?

Eating disorder behaviours begin in adolescence. Few longitudinal studies have investigated childhood risk and protective factors.

To investigate the prevalence of eating disorder behaviours and cognitions and associated childhood psychological, physical and parental risk factors among a cohort of 14-year-old children.

Data were collected from 6140 boys and girls aged 14 years. Gender-stratified models were used to estimate prospective associations between childhood body dissatisfaction, body mass index (BMI), self-esteem, maternal eating disorder and family economic disadvantage on adolescent eating disorder behaviours and cognitions.

Childhood body dissatisfaction strongly predicted eating disorder cognitions in girls, but only in interaction with BMI in boys. Higher self-esteem had a protective effect, particularly in boys. Maternal eating disorder predicted body dissatisfaction and weight/shape concern in adolescent girls and dieting in boys.

Risk factors for eating disorder behaviours and cognitions vary according to gender. Prevention strategies should be gender-specific and target modifiable predictors in childhood and early adolescence.

No study has so far explored differences in discrimination reported by people with major depressive disorder (MDD) across countries and cultures.

To (a) compare reported discrimination across different countries, and (b) explore the relative weight of individual and contextual factors in explaining levels of reported discrimination in people with MDD.

Cross-sectional multisite international survey (34 countries worldwide) of 1082 people with MDD. Experienced and anticipated discrimination were assessed by the Discrimination and Stigma Scale (DISC). Countries were classified according to their rating on the Human Development Index (HDI). Multilevel negative binomial and Poisson models were used.

People living in ‘very high HDI’ countries reported higher discrimination than those in ‘medium/low HDI’ countries. Variation in reported discrimination across countries was only partially explained by individual-level variables. The contribution of country-level variables was significant for anticipated discrimination only.

Contextual factors play an important role in anticipated discrimination. Country-specific interventions should be implemented to prevent discrimination towards people with MDD.

Lithium inhibits glycogen synthase kinase-3, an enzyme implicated in the pathogenesis of dementia.

To examine the association of lithium and dementia risk in a large claims-based US cohort of publicly insured older adults with bipolar disorder.

The cohort included individuals ⩾50 years diagnosed with bipolar disorder who did not receive dementia-related services during the prior year. Each follow-up day was classified by past-year cumulative duration of lithium use (0, 1–60, 61–300 and 301–365 days). Dementia diagnosis was the study outcome. Anticonvulsants commonly used as mood stabilisers served as a negative control.

Compared with non-use, 301–365 days of lithium exposure was associated with significantly reduced dementia risk (hazard ratio (HR) = 0.77, 95% CI 0.60–0.99). No corresponding association was observed for shorter lithium exposures (HR = 1.04, 95% CI 0.83–1.31 for 61–300 days; HR = 1.07, 95% CI 0.67–1.71 for 1–60 days) or for any exposure to anticonvulsants.

Continuous lithium treatment may reduce dementia risk in older adults with bipolar disorder.

Evidence suggests that auditory hallucinations may result from abnormally enhanced auditory sensitivity.

To investigate whether there is an auditory processing bias in healthy individuals who are prone to experiencing auditory hallucinations.

Two hundred healthy volunteers performed a temporal order judgement task in which they determined whether an auditory or a visual stimulus came first under conditions of directed attention (‘attend-auditory’ and ‘attend-visual’ conditions). The Launay–Slade Hallucination Scale was used to divide the sample into high and low hallucination-proneness groups.

The high hallucination-proneness group exhibited a reduced sensitivity to auditory stimuli under the attend-auditory condition. By contrast, attention-directed visual sensitivity did not differ significantly between groups.

Healthy individuals prone to hallucinatory experiences may possess a bias in attention towards internal auditory stimuli at the expense of external sounds. Interventions involving the redistribution of attentional resources would have therapeutic benefit in patients experiencing auditory hallucinations.

Depression is common and tends to be recurrent. Alternative treatments are needed that are non-stigmatising, accessible and can be prescribed by general medical practitioners.

To compare the effectiveness of three interventions for depression: physical exercise, internet-based cognitive–behavioural therapy (ICBT) and treatment as usual (TAU). A secondary aim was to assess changes in self-rated work capacity.

A total of 946 patients diagnosed with mild to moderate depression were recruited through primary healthcare centres across Sweden and randomly assigned to one of three 12-week interventions (trail registry: KCTR study ID: KT20110063). Patients were reassessed at 3 months (response rate 78%).

Patients in the exercise and ICBT groups reported larger improvements in depressive symptoms compared with TAU. Work capacity improved over time in all three groups (no significant differences).

Exercise and ICBT were more effective than TAU by a general medical practitioner, and both represent promising non-stigmatising treatment alternatives for patients with mild to moderate depression.

Patients with a severe mental illness (SMI) are more likely to experience victimisation than the general population.

To examine the prevalence of victimisation in people with SMI, and the relationship between symptoms, treatment facility and indices of substance use/misuse and perpetration, in comparison with the general population.

Victimisation was assessed among both randomly selected patients with SMI (n = 216) and the general population (n=10 865).

Compared with the general population, a high prevalence of violent victimisation was found among the SMI group (22.7% v. 8.5%). Compared with out-patients and patients in a sheltered housing facility, in-patients were most often victimised (violent crimes: 35.3%; property crimes: 47.1%). Risk factors among the SMI group for violent victimisation included young age and disorganisation, and risk factors for property crimes included being an in-patient, disorganisation and cannabis use. The SMI group were most often assaulted by someone they knew.

Caregivers should be aware that patients with SMI are at risk of violent victimisation. Interventions need to be developed to reduce this vulnerability.
