Vitiligo is an acquired, autoimmune depigmenting skin disorder that may affect psychological well-being.
Aims
To determine the risk and impact of psychological comorbidity in people with new-onset vitiligo.
Method
We conducted a retrospective observational study, using UK general practice data (2004–2020). Adults diagnosed with vitiligo (n = 7224) were matched 1:4 with controls (n = 28 880). Associations within 2 years of diagnosis were assessed for psychological conditions: recurrent depressive disorder (RDD), depressive episodes, non-phobia-related anxiety disorder, social phobia, adjustment disorder, substance misuse, self-harm and suicide attempts. Healthcare utilisation, time off work and unemployment within 1 year were compared in those with and without a mental health condition at vitiligo diagnosis.
Results
At diagnosis, people with vitiligo had a similar prevalence of mental health conditions as controls, except for anxiety disorder (cases 7.9%, controls 7.0%; P = 0.014). Incident RDD and anxiety disorder were more common in people with vitiligo (RDD: adjusted hazard ratio (aHR) 1.25, 95% CI 1.01–1.55; anxiety disorder: aHR 1.23, 95% CI 1.00–1.51). Risk was highest in Black and minority ethnic individuals (RDD: aHR 1.72, 95% CI 1.06–2.79; depressive episodes: aHR 1.56, 95% CI 1.03–2.37). No association was found with other mental health conditions. People with vitiligo and psychological comorbidity had more primary care encounters, more time off workand higher unemployment.
Conclusions
People with vitiligo have a higher incidence of RDD and anxiety disorder than controls, and this risk increase may be greatest in Black and minority ethnic populations.
Factors that contribute to the early mortality observed in psychotic disorders, specifically obesity, smoking and sedentary behaviour, occur early in the disorder.
Aims
We aimed to determine whether the integration of a physical health nurse in the care of young people with first-episode psychosis could prevent clinically significant weight gain (≥7% body weight). Secondary outcomes included rates of smoking, metabolic syndrome and sedentary behaviour.
Method
In this single-blind, randomised controlled trial, participants who had received under 4 weeks of antipsychotic medication were randomly allocated to either the intervention (addition of a physical health nurse to their care) or treatment as usual (TAU) for 12 weeks.
Results
Of the 77 participants, there were follow-up data for 86.8% (n = 33) of the intervention group and 82.1% (n = 32) of the TAU group. After 12 weeks, 27.3% of the intervention group experienced clinically significant weight gain compared with 34.4% of the TAU group (odds ratio 0.72, 95% CI 0.25–2.06, P = 0.54). After 6 months, 40.7% of the intervention group gained clinically significant weight compared with 44.1% of the TAU group (P = 0.79). There was no difference in mean change in weight between groups after 12 weeks (2.6 kg v. 2.9 kg, P = 0.87) or 6 months (3.6 kg v. 4.3 kg, P = 0.64). There were no differences in the rates of tobacco smoking cessation, prevalence of metabolic syndrome or physical activity levels.
Conclusions
This intervention failed to prevent the metabolic complications that are highly prevalent in psychotic disorders in the short to medium term, indicating that more intensive interventions are required.
Cognitive impairments are well-established features of psychotic disorders and are present when individuals are at ultra-high risk for psychosis. However, few interventions target cognitive functioning in this population.
Aims
To investigate whether omega-3 polyunsaturated fatty acid (n−3 PUFA) supplementation improves cognitive functioning among individuals at ultra-high risk for psychosis.
Method
Data (N = 225) from an international, multi-site, randomised controlled trial (NEURAPRO) were analysed. Participants were given omega-3 supplementation (eicosapentaenoic acid and docosahexaenoic acid) or placebo over 6 months. Cognitive functioning was assessed with the Brief Assessment of Cognition in Schizophrenia (BACS). Mixed two-way analyses of variance were computed to compare the change in cognitive performance between omega-3 supplementation and placebo over 6 months. An additional biomarker analysis explored whether change in erythrocyte n−3 PUFA levels predicted change in cognitive performance.
Results
The placebo group showed a modest greater improvement over time than the omega-3 supplementation group for motor speed (ηp2 = 0.09) and BACS composite score (ηp2 = 0.21). After repeating the analyses without individuals who transitioned, motor speed was no longer significant (ηp2 = 0.02), but the composite score remained significant (ηp2 = 0.02). Change in erythrocyte n-3 PUFA levels did not predict change in cognitive performance over 6 months.
Conclusions
We found no evidence to support the use of omega-3 supplementation to improve cognitive functioning in ultra-high risk individuals. The biomarker analysis suggests that this finding is unlikely to be attributed to poor adherence or consumption of non-trial n−3 PUFAs.
Loneliness is linked to many negative health outcomes and places strain on the economy and the National Health Service in the United Kingdom. To combat these issues, the determinants of loneliness need to be fully understood. Although friendships have been shown to be particularly important in relation to loneliness in older adults, this association has thus far not been explored more closely. Our exploratory study examines the relationship between number of friends and loneliness, depression, anxiety and stress in older adults. Data were obtained from 335 older adults via completion of an online survey. Measures included loneliness (UCLA Loneliness Scale version 3), depression, anxiety and stress (Depression Anxiety Stress Scales DASS-21). Participants also reported their number of close friends. Regression analyses revealed an inverse curvilinear relationship between number of friends and each of the measures tested. Breakpoint analyses demonstrated a threshold for the effect of number of friends on each of the measures (loneliness = 4, depression = 2, anxiety = 3, stress = 2). The results suggest that there is a limit to the benefit of increasing the number of friends in older adults for each of these measures. The elucidation of these optimal thresholds can inform the practice of those involved in loneliness interventions for older adults. These interventions can become more targeted; focusing on either establishing four close friendships, increasing the emotional closeness of existing friendships or concentrating resources on other determinants of loneliness in this population.
Parents of children with eczema or psoriasis experience high levels of parenting stress, which can negatively impact their child’s mental and physical health.
Aims:
We aimed to investigate the effectiveness, feasibility and acceptability of a mindful parenting intervention for parents of children with eczema or psoriasis.
Method:
Seven parents of children (4–12 years old) with eczema or psoriasis took part in an 8-week mindful parenting group intervention. A single-case experimental design was adopted, whereby parents completed daily idiographic measures of parenting stress related to their child’s skin condition. Parents also completed standardised questionnaires measuring their parenting stress, depression, anxiety and quality of life, and children completed a quality of life measure, at four time points: baseline, pre-intervention, post-intervention and 6-week follow-up. Parents provided qualitative feedback after the intervention.
Results:
All parents completed the intervention and showed improvements in idiographic measures of parenting stress from baseline to follow-up. Improvements in parenting stress were larger at follow-up than post-intervention, suggesting the benefits of intervention continue beyond the intervention. Six of seven parent–child dyads showed improvement in at least one of the wellbeing measures, from pre-intervention to post-intervention or follow-up. Feasibility was demonstrated through good participant retention, adherence to home practice, and treatment fidelity. Acceptability was demonstrated through positive parent evaluations of the intervention.
Conclusions:
Mindful parenting can be an effective, feasible and acceptable intervention for parents of children with eczema or psoriasis. Future studies should attempt to replicate the findings through randomised controlled trials.
From 2014 to 2020, we compiled radiocarbon ages from the lower 48 states, creating a database of more than 100,000 archaeological, geological, and paleontological ages that will be freely available to researchers through the Canadian Archaeological Radiocarbon Database. Here, we discuss the process used to compile ages, general characteristics of the database, and lessons learned from this exercise in “big data” compilation.
We examined whether preadmission history of depression is associated with less delirium/coma-free (DCF) days, worse 1-year depression severity and cognitive impairment.
Design and measurements:
A health proxy reported history of depression. Separate models examined the effect of preadmission history of depression on: (a) intensive care unit (ICU) course, measured as DCF days; (b) depression symptom severity at 3 and 12 months, measured by the Beck Depression Inventory-II (BDI-II); and (c) cognitive performance at 3 and 12 months, measured by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) global score.
Setting and participants:
Patients admitted to the medical/surgical ICU services were eligible.
Results:
Of 821 subjects eligible at enrollment, 261 (33%) had preadmission history of depression. After adjusting for covariates, preadmission history of depression was not associated with less DCF days (OR 0.78, 95% CI, 0.59–1.03 p = 0.077). A prior history of depression was associated with higher BDI-II scores at 3 and 12 months (3 months OR 2.15, 95% CI, 1.42–3.24 p = <0.001; 12 months OR 1.89, 95% CI, 1.24–2.87 p = 0.003). We did not observe an association between preadmission history of depression and cognitive performance at either 3 or 12 months (3 months beta coefficient −0.04, 95% CI, −2.70–2.62 p = 0.97; 12 months 1.5, 95% CI, −1.26–4.26 p = 0.28).
Conclusion:
Patients with a depression history prior to ICU stay exhibit a greater severity of depressive symptoms in the year after hospitalization.
Accumulating evidence suggests that alterations in inflammatory biomarkers are important in depression. However, previous meta-analyses disagree on these associations, and errors in data extraction may account for these discrepancies.
Methods
PubMed/MEDLINE, Embase, PsycINFO, and the Cochrane Library were searched from database inception to 14 January 2020. Meta-analyses of observational studies examining the association between depression and levels of tumor necrosis factor-α (TNF-α), interleukin 1-β (IL-1β), interleukin-6 (IL-6), and C-reactive protein (CRP) were eligible. Errors were classified as follows: incorrect sample sizes, incorrectly used standard deviation, incorrect participant inclusion, calculation error, or analysis with insufficient data. We determined their impact on the results after correction thereof.
Results
Errors were noted in 14 of the 15 meta-analyses included. Across 521 primary studies, 118 (22.6%) showed the following errors: incorrect sample sizes (20 studies, 16.9%), incorrect use of standard deviation (35 studies, 29.7%), incorrect participant inclusion (7 studies, 5.9%), calculation errors (33 studies, 28.0%), and analysis with insufficient data (23 studies, 19.5%). After correcting these errors, 11 (29.7%) out of 37 pooled effect sizes changed by a magnitude of more than 0.1, ranging from 0.11 to 1.15. The updated meta-analyses showed that elevated levels of TNF- α, IL-6, CRP, but not IL-1β, are associated with depression.
Conclusions
These findings show that data extraction errors in meta-analyses can impact findings. Efforts to reduce such errors are important in studies of the association between depression and peripheral inflammatory biomarkers, for which high heterogeneity and conflicting results have been continuously reported.
Psychotic experiences are reported by 5–10% of young people, although only a minority persist and develop into psychotic disorders. It is unclear what characteristics differentiate those with transient psychotic experiences from those with persistent psychotic experiences that are more likely to be of clinical relevance.
Aims
To investigate how longitudinal profiles of psychotic experiences, created from assessments at three different time points, are influenced by early life and co-occurring factors.
Method
Using data from 8045 individuals from a birth cohort study, longitudinal profiles of psychotic experiences based on semi-structured interviews conducted at 12, 18 and 24 years were defined. Environmental, cognitive, psychopathological and genetic determinants of these profiles were investigated, along with concurrent changes in psychopathology and cognition.
Results
Following multiple imputations, the distribution of longitudinal profiles of psychotic experiences was none (65.7%), transient (24.1%), low-frequency persistent (8.4%) and high-frequency persistent (1.7%). Individuals with high-frequency persistent psychotic experiences were more likely to report traumatic experiences, other psychopathology, a more externalised locus of control, reduced emotional stability and conscientious personality traits in childhood, compared with those with transient psychotic experiences. These characteristics also differed between those who had any psychotic experiences and those who did not.
Conclusions
These findings indicate that the same risk factors are associated with incidence as with persistence of psychotic experiences. Thus, it might be that the severity of exposure, rather than the presence of specific disease-modifying factors, is most likely to determine whether psychotic experiences are transient or persist, and potentially develop into a clinical disorder over time.
The COVID-19 pandemic has disrupted lives and livelihoods, and people already experiencing mental ill health may have been especially vulnerable.
Aims
Quantify mental health inequalities in disruptions to healthcare, economic activity and housing.
Method
We examined data from 59 482 participants in 12 UK longitudinal studies with data collected before and during the COVID-19 pandemic. Within each study, we estimated the association between psychological distress assessed pre-pandemic and disruptions since the start of the pandemic to healthcare (medication access, procedures or appointments), economic activity (employment, income or working hours) and housing (change of address or household composition). Estimates were pooled across studies.
Results
Across the analysed data-sets, 28% to 77% of participants experienced at least one disruption, with 2.3–33.2% experiencing disruptions in two or more domains. We found 1 s.d. higher pre-pandemic psychological distress was associated with (a) increased odds of any healthcare disruptions (odds ratio (OR) 1.30, 95% CI 1.20–1.40), with fully adjusted odds ratios ranging from 1.24 (95% CI 1.09–1.41) for disruption to procedures to 1.33 (95% CI 1.20–1.49) for disruptions to prescriptions or medication access; (b) loss of employment (odds ratio 1.13, 95% CI 1.06–1.21) and income (OR 1.12, 95% CI 1.06 –1.19), and reductions in working hours/furlough (odds ratio 1.05, 95% CI 1.00–1.09) and (c) increased likelihood of experiencing a disruption in at least two domains (OR 1.25, 95% CI 1.18–1.32) or in one domain (OR 1.11, 95% CI 1.07–1.16), relative to no disruption. There were no associations with housing disruptions (OR 1.00, 95% CI 0.97–1.03).
Conclusions
People experiencing psychological distress pre-pandemic were more likely to experience healthcare and economic disruptions, and clusters of disruptions across multiple domains during the pandemic. Failing to address these disruptions risks further widening mental health inequalities.
This special issue is devoted to highlighting thinkers who have been overlooked within business ethics and who have important contributions to make to our field. We make the case that, as scholars of a hybrid discipline that also aims to address important issues of business practice, we need to look continually for new sources of insight and wisdom that can both enrich our discourse and improve our ability to generate ideas that have a positive impact on business practice. In this introductory essay, we discuss our rationale for creating this special issue, summarize the articles contained within, and close with thoughts on its significance for the field going forward.
Motivated by the desire to understand complex transient behaviour in fluid flows, we study the dynamics of an air bubble driven by the steady motion of a suspending viscous fluid within a Hele-Shaw channel with a centred depth perturbation. Using both experiments and numerical simulations of a depth-averaged model, we investigate the evolution of an initially centred bubble of prescribed volume as a function of flow rate and initial shape. The experiments exhibit a rich variety of organised transient dynamics, involving bubble breakup as well as aggregation and coalescence of interacting neighbouring bubbles. The long-term outcome is either a single bubble or multiple separating bubbles, positioned along the channel in order of increasing velocity. Up to moderate flow rates, the life and fate of the bubble are reproducible and can be categorised by a small number of characteristic behaviours that occur in simply connected regions of the parameter plane. Increasing the flow rate leads to less reproducible time evolutions with increasing sensitivity to initial conditions and perturbations in the channel. Time-dependent numerical simulations that allow for breakup and coalescence are found to reproduce most of the dynamical behaviour observed experimentally, including enhanced sensitivity at high flow rate. An unusual feature of this system is that the set of steady and periodic solutions can change during temporal evolution because both the number of bubbles and their size distribution evolve due to breakup and coalescence events. Calculation of stable and unstable solutions in the single- and two-bubble cases reveals that the transient dynamics is orchestrated by weakly unstable solutions of the system that can appear and disappear as the number of bubbles changes.
The coronavirus disease 2019 (COVID-19) pandemic is likely to lead to a significant increase in mental health disorders among healthcare workers (HCW).
Aims
We evaluated the rates of anxiety, depressive and post-traumatic stress disorder (PTSD) symptoms in a population of HCW in the UK.
Method
An electronic survey was conducted between the 5 June 2020 and 31 July 2020 of all hospital HCW in the West Midlands, UK using clinically validated questionnaires: the 4-item Patient Health Questionnaire(PHQ-4) and the Impact of Event Scale-Revised (IES-R). Univariate analyses and adjusted logistic regression analyses were performed to estimate the strengths in associations between 24 independent variables and anxiety, depressive or PTSD symptoms.
Results
There were 2638 eligible participants who completed the survey (female: 79.5%, median age: 42 years, interquartile range: 32–51). The rates of clinically significant symptoms of anxiety, depression and PTSD were 34.3%, 31.2% and 24.5%, respectively. In adjusted analysis a history of mental health conditions was associated with clinically significant symptoms of anxiety (odds ratio (OR) = 2.3, 95% CI 1.9–2.7, P < 0.001), depression (OR = 2.5, 95% CI 2.1–3.0, P < 0.001) and PTSD (OR = 2.1, 95% CI 1.7–2.5, P < 0.001). The availability of adequate personal protective equipment (PPE), well-being support and lower exposure to moral dilemmas at work demonstrated significant negative associations with these symptoms (P ≤ 0.001).
Conclusions
We report higher rates of clinically significant mental health symptoms among hospital HCW following the initial COVID-19 pandemic peak in the UK. Those with a history of mental health conditions were most at risk. Adequate PPE availability, access to well-being support and reduced exposure to moral dilemmas may protect hospital HCW from mental health symptoms.
COVID-19-related morbidity and mortality have disproportionately affected communities of colour across the United States. Originally dubbed the ‘great equalizer’, many individuals believed that COVID-19 affected everyone equally (Gupta, 2020). However, COVID-19 has exposed ethnic and racial differences in morbidity and mortality (Yaya et al, 2020). Early data showed that African Americans, Latinos and Native Americans were more likely to grow ill and die from COVID-19 than White Americans (Bassett et al, 2020). As data continues to emerge, it is evident that communities of colour bear a disproportionate burden of COVID-19. Thus, relevant COVID-19 data must be viewed as a foundation for conducting health disparities research.
Health disparities research identifies groups that receive inequitable access to care, treatment and resources (Chan et al, 2018). This research is necessary because it offers an in-depth understanding of the demographic framework (for example, race, ethnicity, gender, age, socioeconomic status, marital status and ability status) for addressing COVID-19 (Chan et al, 2018). Zastrow and Kirst-Ashman (2010) posited that academic researchers should encompass cultural competence and cultural sensitivity when investigating the behaviour and social environment of specific groups. See (2007) suggested that Eurocentric research may generate a misunderstanding of the issues that communities of colour face in light of COVID-19. Therefore, establishing multicultural and multidisciplinary research teams with an inherent understanding of health disparities is paramount to understanding communities of colour.
Since the onset of the COVID-19 global pandemic, academic researchers were forced to change approaches to research and building teams (Kupferschmidt, 2020). These rapid changes were driven by the infectivity of COVID-19 and the need to socially distance and isolate. Fortunately, technology, such as Cisco WebEx, enabled a newly created diverse research team to work without geographical constraints to facilitate COVID-19 research. The purpose of this chapter is to describe how a diverse research team worked together to conduct meaningful research regarding the impact of stress and coping in the age of COVID-19. Colleagues from the University of Nevada, Las Vegas (UNLV) and the University of Wisconsin, Madison led the development of a social mediadisseminated research project.
The UK Diabetes and Diet Questionnaire (UKDDQ) is a brief dietary questionnaire developed for people with, or at high risk of, type 2 diabetes(1). It consists of 20 items scored from 0–5 (0 healthiest, 5 least healthy). It has been demonstrated to be reliable and compares well with food diaries. A study evaluating sensitivity to change of the UKDDQ was undertaken at the specialist weight management service (WMS) at Musgrove Park Hospital, Taunton. WMS patients receive an initial appointment with an endocrinologist and dietitian, followed by referral to group sessions or dietary advice. Follow up appointments with a WMS specialist occur over the next 26 weeks. Adults attending the service were recruited for the study between September 2016-March 2017. Participants completed the UKDDQ in the waiting room at the initial appointment and the first follow-up. Diabetes status, binge eating assessment and weight at both timepoints were obtained from WMS records. UKDDQ scores from 0–5 were calculated for each participant by summing the score for each item and dividing by 20. Change in UKDDQ scores and absolute and percentage change in weight between appointments were calculated. Paired sample t-tests were used to test differences in means for UKDDQ scores and weight from baseline to follow up. Multivariable regression analysis was used to examine associations between changes in the UKDDQ scores and percentage change in weight. The model was adjusted for age, gender, follow up time, diabetes status and binge eating. Forty-eight White British participants completed the study (67% women, 37% type 2 diabetes, 29% binge eating). Baseline mean weight was 132.4 (29.4)kg, mean BMI 46.5(7.7)kg/m2 and mean UKDDQ score was 1.39 (0.49). Participants lost weight (-2.4 (6.9)kg, p = 0.006) and the UKDDQ score improved between baseline and follow up (-0.27(0.53), p = 0.001). The mean percentage weight change was -1.6 (5.0)%. There was some evidence that a one point deterioration in healthy eating was associated with a 2.4 (-0.2 to 5.1)% increase in weight (p = 0.072). The UKDDQ can measure dietary change in people attending a specialist WMS and there is some evidence that a change in score is associated with a change in weight. The UKDDQ could be used as an outcome measure in these services.
Heterotrophic soil protists encompass lineages that are both evolutionarily ancient and highly diverse, providing an untapped wealth of scientific insight. Yet the diversity of free-living heterotrophic terrestrial protists is still largely unknown. To contribute to our understanding of this diversity, we present a checklist of heterotrophic protists currently reported from terrestrial Antarctica, for which no comprehensive evaluation currently exists. As a polar continent, Antarctica is especially susceptible to rising temperatures caused by anthropogenic climate change. Establishing a baseline for future conservation efforts of Antarctic protists is therefore important. We performed a literature search and found 236 taxa identified to species and an additional 303 taxa identified to higher taxonomic levels in 54 studies spanning over 100 years of research. Isolated by distance, climate and the circumpolar vortex, Antarctica is the most extreme continent on Earth: it is not unreasonable to think that it may host physiologically and evolutionarily unique species of protists, yet currently most species discovered in Antarctica are considered cosmopolitan. Additional sampling of the more extreme intra-continental zones will probably result in the discovery of more novel and unique taxa.
Personality disorders are now internationally recognised as a mental health priority. Nevertheless, there are no systematic reviews examining the global prevalence of personality disorders.
Aims
To calculate the worldwide prevalence of personality disorders and examine whether rates vary between high-income countries and low- and middle-income countries (LMICs).
Method
We systematically searched PsycINFO, MEDLINE, EMBASE and PubMed from January 1980 to May 2018 to identify articles reporting personality disorder prevalence rates in community populations (PROSPERO registration number: CRD42017065094).
Results
A total of 46 studies (from 21 different countries spanning 6 continents) satisfied inclusion criteria. The worldwide pooled prevalence of any personality disorder was 7.8% (95% CI 6.1–9.5). Rates were greater in high-income countries (9.6%, 95% CI 7.9–11.3%) compared with LMICs (4.3%, 95% CI 2.6–6.1%). In univariate meta-regressions, significant heterogeneity was partly attributable to study design (two-stage v. one-stage assessment), county income (high-income countries v. LMICs) and interview administration (clinician v. trained graduate). In multiple meta-regression analysis, study design remained a significant predictor of heterogeneity. Global rates of cluster A, B and C personality disorders were 3.8% (95% CI 3.2, 4.4%), 2.8% (1.6, 3.7%) and 5.0% (4.2, 5.9%).
Conclusions
Personality disorders are prevalent globally. Nevertheless, pooled prevalence rates should be interpreted with caution due to high levels of heterogeneity. More large-scale studies with standardised methodologies are now needed to increase our understanding of population needs and regional variations.
Depression is a common, serious, but under-recognised problem in multiple sclerosis (MS). The primary objective of this study was to assess whether a rapid visual analogue screening tool for depression could operate as a quick and reliable screening method for depression, in patients with MS.
Method
Patients attending a regional MS outpatient clinic completed the Emotional Thermometer 7 tool (ET7), the Hospital Anxiety and Depression Scale – Depression Subscale (HADS-D) and the Major Depression Inventory (MDI) to establish a Diagnostic and Statistical Manual, 4th edition (DSM-IV) diagnosis of Major Depression. Full ET7, briefer subset ET4 version and depression and distress thermometers alone were compared with HADS-D and MDI. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and receiver operating characteristic (ROC) curve were calculated to compare the performance of all the screening tools.
Results
In total, 190 patients were included. ET4 performed well as a ‘rule-out’ screening step (sensitivity 0.91, specificity 0.72, NPV 0.98, PPV 0.32). ET4 performance was comparable to HADS-D (sensitivity 0.96, specificity 0.77, NPV 0.99, PPV 0.37) without need for clinician scoring. The briefer ET4 performed as well as the full ET7.
Conclusion
ET are quick, sensitive and useful screening tools for depression in this MS population, to be complemented by further questioning or more detailed psychiatric assessment where indicated. Given that ET4 and ET7 perform equally well, we recommend the use of ET4 as it is briefer. It has the potential to be widely implemented across busy neurology clinics to assist in depression screening in this under diagnosed group.
