Background Insomnia treatment using an internet-based cognitive–behavioural therapy for insomnia (CBT-I) program reduces depression symptoms, anxiety symptoms and suicidal ideation. However, the speed, longevity and consistency of these effects are unknown. Aims To test the following: whether the efficacy of online CBT-I was sustained over 18 months; how rapidly the effects of CBT-I emerged; evidence for distinct trajectories of change in depressive symptoms; and predictors of these trajectories. Method A randomised controlled trial compared the 6-week Sleep Healthy Using the Internet (SHUTi) CBT-I program to an attention control program. Adults ( N =1149) with clinical insomnia and subclinical depression symptoms were recruited online from the Australian community. Results Depression, anxiety and insomnia decreased significantly by week 4 of the intervention period and remained significantly lower relative to control for >18 months (between-group Cohen’s d =0.63, 0.47, 0.55, respectively, at 18 months). Effects on suicidal ideation were only short term. Two depression trajectories were identified using growth mixture models: improving (95%) and stable/deteriorating (5%) symptoms. More severe baseline depression, younger age and limited comfort with the internet were associated with reduced odds of improvement. Conclusions Online CBT-I produced rapid and long-term symptom reduction in people with subclinical depressive symptoms, although the initial effect on suicidal ideation was not sustained.

BackgroundNational Mental Health Survey found that in India, the point prevalence of major depressive disorder (MDD) was 2.7% and the treatment gap was 85.2%, whereas in Madhya Pradesh the point prevalence of MDD was 1.4% and the treatment gap was 80%.AimsTo describe the baseline prevalence of depression among adults, association of various demographic and socioeconomic variables with depression and estimation of contact coverage for the same.MethodPopulation-based cross-sectional survey of 3220 adults in Sehore district of Madhya Pradesh, India. The outcome of interest was a probable diagnosis of depression that was measured using the Patient Health Questionnaire (PHQ-9) and the proportion of individuals with depression (PHQ-9>9) who sought care for the same. The data were analysed using simple and multiple log-linear regression.ResultsLow educational attainment, unemployment and indebtedness were associated with both moderate/severe depression (PHQ-9 score >9) and severe depression only (PHQ-9 score >14), whereas age, caste and marital status were associated with only moderate or severe depression. Religion, type of house, land ownership and amount of loan taken were not associated with either moderate/severe or only severe depression. The contact coverage for moderate/severe depression was 13.08% (95% CI 10.2–16.63).ConclusionsThere is an urgent need to bridge the treatment gap by targeting individuals with social vulnerabilities and integrating evidence-based interventions in primary care.

BackgroundUnidentified depression in primary care is a public health concern, globally. There is a need for brief, valid and easily administered tools in primary care.AimsTo estimate reliability and validity of the newly developed Primary care Screening Questionnaire for Depression (PSQ4D), a four-item tool, with ‘yes’ or ‘no’ options.MethodPSQ4D was administered verbally (time required, n=827) in six primary care settings in Kerala, India. A psychiatrist evaluated each patient on the same day, using ICD-10 Diagnostic Criteria for Research, based on unstructured clinical interview.ResultsThe Cronbach's alpha for internal consistency reliability was 0.80; kappa coefficient for test-retest reliability was 0.9 and that for interrater reliability was 0.72. At a score ≥2, sensitivity was 0.96, specificity was 0.87, positive predictive value was 0.74, negative predictive value was 0.98, positive likelihood ratio was 7.4 and negative likelihood ratio was 0.05.ConclusionsWhen physician administered, PSQ4D has good reliability. At a cut-off score of ≥2, it has high sensitivity and specificity to identify depressive disorder in primary care.

BackgroundExamining neurometabolic abnormalities in critical brain areas in schizophrenia and major depressive disorder (MDD) may help guide future pharmacological interventions including glutamate-modulating treatments.AimsTo measure metabolite concentrations within the anterior cingulate cortex (ACC) and thalamus of people with schizophrenia and people with MDD.MethodsSpectra were acquired from 16 volunteers with schizophrenia, 17 with MDD and 18 healthy controls using magnetic resonance spectroscopy on a 7 Tesla scanner.ResultsIn the thalamus, there were lower glycine concentrations in the schizophrenia group relative to control (P=0.017) and MDD groups (P=0.012), and higher glutamine concentrations relative to healthy controls (P=0.009). In the thalamus and the ACC, the MDD group had lower myo-inositol concentrations than the control (P=0.014, P=0.009, respectively) and schizophrenia (P=0.004, P=0.002, respectively) groups.ConclusionThese results support the glutamatergic theory of schizophrenia and indicate a potential glycine deficiency in the thalamus. In addition, reduced myo-inositol concentrations in MDD suggest its involvement in the disorder.

BackgroundComputerised cognitive-behavioural therapy (CCBT) helps improve mental health outcomes in White populations. However, no studies have examined whether CCBT is acceptable and beneficial for African Americans.AimsWe studied differences in CCBT use and self-reported change in depression and anxiety symptoms among 91 African Americans and 499 White primary care patients aged 18–75, enrolled in a randomised clinical trial of collaborative care embedded with an online treatment for depression and anxiety.MethodPatients with moderate levels of mood and/or anxiety symptoms (PHQ-9 or GAD-7≥10) were randomised to receive either care-manager-guided access to the proven-effective Beating the Blues® CCBT programme or usual care from their primary care doctor.ResultsCompared with White participants, African Americans were less likely to start the CCBT programme (P=0.01), and those who did completed fewer sessions and were less likely to complete the full programme (P=0.03). Despite lower engagement, however, African Americans who started the CCBT programme experienced a greater decrease in self-reported depressive symptoms (estimated 8-session change: −6.6 v. −5.5; P=0.06) and similar decrease in anxiety symptoms (−5.3 v. −5.6; P=0.80) compared with White participants.ConclusionsCCBT may be an efficient and scalable first-step to improving minority mental health and reducing disparities in access to evidence-based healthcare.

BackgroundSymptoms of anxiety and depression are prevalent in older adults.AimsTo compare clinician-guided and self-guided versions of a transdiagnostic internet-delivered cognitive–behavioural therapy (iCBT) intervention for adults aged 60 years and above.MethodAdults (n=433) with symptoms of anxiety and depression were randomly allocated to: (1) clinician-guided treatment (n=153); (2) initial clinician interview followed by self-guided treatment (n=140); or (3) self-guided treatment without interview (n=140).ResultsLarge reductions (d ≥1.00) in symptoms of depression and anxiety were observed across groups, and sustained at follow-up. No differences were observed in clinical outcomes or satisfaction ratings. Age did not affect outcomes.ConclusionsCarefully developed iCBT interventions may significantly reduce symptoms of anxiety and depression in older adults when delivered in either clinician-guided or self-guided formats.

BackgroundThe mental health outcomes of military personnel deployed on peacekeeping missions have been relatively neglected in the military mental health literature.AimsTo assess the mental health impacts of peacekeeping deployments.MethodIn total, 1025 Australian peacekeepers were assessed for current and lifetime psychiatric diagnoses, service history and exposure to potentially traumatic events (PTEs). A matched Australian community sample was used as a comparator. Univariate and regression analyses were conducted to explore predictors of psychiatric diagnosis.ResultsPeacekeepers had significantly higher 12-month prevalence of post-traumatic stress disorder (16.8%), major depressive episode (7%), generalised anxiety disorder (4.7%), alcohol misuse (12%), alcohol dependence (11.3%) and suicidal ideation (10.7%) when compared with the civilian comparator. The presence of these psychiatric disorders was most strongly and consistently associated with exposure to PTEs.ConclusionsVeteran peacekeepers had significant levels of psychiatric morbidity. Their needs, alongside those of combat veterans, should be recognised within military mental health initiatives.

BackgroundIntellectual ability may be an endophenotypic marker for bipolar disorder.AimsWithin a large birth cohort, we aimed to assess whether childhood IQ (including both verbal IQ (VIQ) and performance IQ (PIQ) subscales) was predictive of lifetime features of bipolar disorder assessed in young adulthood.MethodWe used data from the Avon Longitudinal Study of Parents and Children (ALSPAC), a large UK birth cohort, to test for an association between measures of childhood IQ at age 8 years and lifetime manic features assessed at age 22–23 years using the Hypomania Checklist-32 (HCL-32; n=1881 individuals). An ordinary least squares linear regression model was used, with normal childhood IQ (range 90–109) as the referent group. We adjusted analyses for confounding factors, including gender, ethnicity, handedness, maternal social class at recruitment, maternal age, maternal history of depression and maternal education.ResultsThere was a positive association between IQ at age 8 years and lifetime manic features at age 22–23 years (Pearson's correlation coefficient 0.159 (95% CI 0.120–0.198), P>0.001). Individuals in the lowest decile of manic features had a mean full-scale IQ (FSIQ) which was almost 10 points lower than those in the highest decile of manic features: mean FSIQ 100.71 (95% CI 98.74–102.6) v. 110.14 (95% CI 107.79–112.50), P>0.001. The association between IQ and manic features was present for FSIQ, VIQ and for PIQ but was strongest for VIQ.ConclusionsA higher childhood IQ score, and high VIQ in particular, may represent a marker of risk for the later development of bipolar disorder. This finding has implications for understanding of how liability to bipolar disorder may have been selected through generations. It will also inform future genetic studies at the interface of intelligence, creativity and bipolar disorder and is relevant to the developmental trajectory of bipolar disorder. It may also improve approaches to earlier detection and treatment of bipolar disorder in adolescents and young adults.

Background Transition from at-risk state to full syndromal mental disorders is underexplored for unipolar and bipolar disorders compared with psychosis. Aims Prospective, trans-diagnostic study of rates and predictors of early transition from sub-threshold to full syndromal mental disorder. Method One-year outcome of 243 consenting youth aged 15–25 years with a sub-syndromal presentation of a potentially severe mental disorder. Survival analysis and odds ratio (OR) for predictors of transition identified from baseline clinical and demographic ratings. Results About 17% ( n =36) experienced transition to a major mental disorder. Independent of syndromal diagnosis, transition was significantly more likely in individuals who were NEET (not in education, employment or training), in females and in those with more negative psychological symptoms (e.g. social withdrawal). Conclusions NEET status and negative symptoms are modifiable predictors of illness trajectory across diagnostic categories and are not specific to transition to psychosis.

BackgroundPeople living in low- and middle-income countries (LMIC) are at increased risk for exposure to major natural disasters, which places them at increased risk for mental health problems. Evidence is less clear, however, regarding the effects of less severe but more frequent natural disasters, which are likely to increase due to global climate change.AimsTo examine the mental health and life functioning, and their predictors, of people living in central coastal Vietnam – an area characterised by high risk for natural disasters and poverty.MethodOne thousand individuals were randomly selected from five provinces in central coastal Vietnam. Individuals were assessed cross-sectionally for exposure to major storms and other traumatic events (Post-traumatic Diagnostic Scale, or PDS), financial stress (Chronic Financial Stress Scale), depression (PHQ-9), anxiety (GAD-7), post-traumatic stress disorder (PTSD) (PDS), somatic syndrome (SCL-90-R), alcohol dependence (ICD-10), self-perceived general physical health (SF-36), and functional impairment (PDS life functioning section); caseness was determined using the various measures' algorithms.Results22.7% of the sample (n=227) met caseness criteria in one or more mental health domains, and 22.1% (n=221) reported moderate to severe functional impairment. Lifetime exposure to typhoons and other major storms was 99% (n=978), with 77% (n=742) reporting traumatic major storm exposure. Moderate to high levels of financial stress were reported by 30% (n=297). Frequency of exposure to major storms was not associated with increased risk for mental health problems but traumatic exposure to a major storm was. Overall, the strongest predictor of mental health problems was financial stress. Number of traumatic typhoons and other major storms in turn were significant predictors (r2=0.03) of financial stress. The primary predictor of alcohol dependence was male gender, highlighting the importance of gender roles in development of alcohol abuse in countries like Vietnam.ConclusionsIndividuals living in central coastal Vietnam have elevated rates of PTSD, somatic syndrome, and functional impairment but not depression or anxiety. Financial stress was the strongest predictor of mental health problems. Results suggest the importance of conducting broad assessments when providing mental health support for disaster-impacted communities. Study results suggest that one indirect consequence of predicted global climate change may be increased prevalence of mental health problems in communities such as that assessed in the present study, due to increased risk for traumatic storm-related exposure and through indirect effects on financial stress, but not through a general increased risk for major storms. Such results also indicate that when supporting LMIC communities that have experienced natural disasters, it will be important to consider the broader community context including poverty, in addition to the direct effects of the disaster.

Background At present, we do not have any biological tests which can contribute towards a diagnosis of depression. Neuroimaging measures have shown some potential as biomarkers for diagnosis. However, participants have generally been from the same ethnic background while the applicability of a biomarker would require replication in individuals of diverse ethnicities. Aims We sought to examine the diagnostic potential of the structural neuroanatomy of depression in a sample of a wide ethnic diversity. Method Structural magnetic resonance imaging (MRI) scans were obtained from 23 patients with major depressive disorder in an acute depressive episode (mean age: 39.8 years) and 20 matched healthy volunteers (mean age: 38.8 years). Participants were of Asian, African and Caucasian ethnicity recruited from the general community. Results Structural neuroanatomy combining white and grey matter distinguished patients from controls at the highest accuracy of 81% with the most stable pattern being at around 70%. A widespread network encompassing frontal, parietal, occipital and cerebellar regions contributed towards diagnostic classification. Conclusions These findings provide an important step in the development of potential neuroimaging-based tools for diagnosis as they demonstrate that the identification of depression is feasible within a multi-ethnic group from the community.

BackgroundInternet cognitive–behavioural therapy (iCBT) for panic disorder of up to 10 lessons is well established. The utility of briefer programmes is unknown.AimsTo determine the efficacy and effectiveness of a five-lesson iCBT programme for panic disorder.MethodStudy 1 (efficacy): Randomised controlled trial comparing active iCBT (n=27) and waiting list control participants (n=36) on measures of panic severity and comorbid symptoms. Study 2 (effectiveness): 330 primary care patients completed the iCBT programme under the supervision of primary care practitioners.ResultsiCBT was significantly more effective than waiting list control in reducing panic (g=0.97, 95% CI 0.34 to 1.61), distress (g=0.92, 95% CI 0.28 to 1.55), disability (g=0.81, 95% CI 0.19 to 1.44) and depression (g=0.79, 95% CI 0.17 to 1.41), and gains were maintained at 3 months post-treatment (iCBT group). iCBT remained effective in primary care, but lower completion rates were found (56.1% in study 2 v. 63% in study 1). Adherence appeared to be related to therapist contact.ConclusionsThe five-lesson Panic Program has utility for treating panic disorder, which translates to primary care. Adherence may be enhanced with therapist contact.

Bipolar disorder is burdensome for the individual and for society; it is associated with significant functional impairment, high comorbidity, lower quality of life and higher rates of suicide. 1 Pharmacotherapy with mood stabilisers and antipsychotics may not lead to sustained remission and more than two-thirds of those treated experience a recurrence within 5 years. 2 Given such poor treatment outcomes, novel approaches to improve therapeutic interventions are an important objective of bipolar disorder research. Mounting, albeit inconsistent, evidence suggests that testosterone may play a role in the pathophysiology of mood disorders. 3 However, the effects of testosterone are complex: the hormonal disorder polycystic ovarian syndrome is characterised by chronically increased testosterone levels and is associated with significantly increased depression, 4 but paradoxically, amelioration of depression has been found following testosterone administration in males 5 and females; 6–8 low testosterone levels have been reported in certain subgroups of men with depression; 9 androgen-induced hypomania has been reported; 10 and high testosterone levels may predict suicidal behaviour in women with bipolar disorder. 3 Further evidence clarifying the relationship between testosterone and bipolar disorder might pave the way for exploring the use of pharmacological strategies that optimise testosterone levels in patients with bipolar disorder. We therefore assessed testosterone levels in bipolar disorder and healthy controls and sought to explore whether this was different between males and females and whether there was a relationship between testosterone, mood and cognition.
