Long-term participant retention and engagement patterns in an app and wearable-based multinational remote digital depression study. NPJ Digit Med 2023; 6:25.

Abstract
Recent growth in digital technologies has enabled the recruitment and monitoring of large and diverse populations in remote health studies. However, the generalizability of inference drawn from remotely collected health data could be severely impacted by uneven participant engagement and attrition over the course of the study. We report findings on long-term participant retention and engagement patterns in a large multinational observational digital study for depression containing active (surveys) and passive sensor data collected via Android smartphones, and Fitbit devices from 614 participants for up to 2 years. Majority of participants (67.6%) continued to remain engaged in the study after 43 weeks. Unsupervised clustering of participants' study apps and Fitbit usage data showed 3 distinct engagement subgroups for each data stream. We found: (i) the least engaged group had the highest depression severity (4 PHQ8 points higher) across all data streams; (ii) the least engaged group (completed 4 bi-weekly surveys) took significantly longer to respond to survey notifications (3.8 h more) and were 5 years younger compared to the most engaged group (completed 20 bi-weekly surveys); and (iii) a considerable proportion (44.6%) of the participants who stopped completing surveys after 8 weeks continued to share passive Fitbit data for significantly longer (average 42 weeks). Additionally, multivariate survival models showed participants' age, ownership and brand of smartphones, and recruitment sites to be associated with retention in the study. Together these findings could inform the design of future digital health studies to enable equitable and balanced data collection from diverse populations.

J Affect Disord 2021; 295:1269-1279. [PMID: 34706441 DOI: 10.1016/j.jad.2021.08.108] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Revised: 08/06/2021] [Accepted: 08/30/2021] [Indexed: 12/28/2022]
Abstract
BACKGROUND In longitudinal research, switching between diagnoses should be considered when examining patients with depression and anxiety. We investigated course trajectories of affective disorders over a nine-year period, comparing a categorical approach using diagnoses to a dimensional approach using symptom severity. METHOD Patients with a current depressive and/or anxiety disorder at baseline (N = 1701) were selected from the Netherlands Study of Depression and Anxiety (NESDA). Using psychiatric diagnoses, we described 'consistently recovered,' 'intermittently recovered,' 'intermittently recurrent', and 'consistently chronic' at two-, four-, six-, and nine-year follow-up. Additionally, latent class growth analysis (LCGA) using depressive, anxiety, fear, and worry symptom severity scores was used to identify distinct classes. RESULTS Considering the categorical approach, 8.5% were chronic, 32.9% were intermittently recurrent, 37.6% were intermittently recovered, and 21.0% remained consistently recovered from any affective disorder at nine-year follow-up. In the dimensional approach, 66.6% were chronic, 25.9% showed partial recovery, and 7.6% had recovered. LIMITATIONS 30.6% of patients were lost to follow-up. Diagnoses were rated by the interviewer and questionnaires were completed by the participant. CONCLUSIONS Using diagnoses alone as discrete categories to describe clinical course fails to fully capture the persistence of affective symptoms that were observed when using a dimensional approach. The enduring, fluctuating presence of subthreshold affective symptoms likely predisposes patients to frequent relapse. The commonness of subthreshold symptoms and their adverse impact on long-term prognoses deserve continuous clinical attention in mental health care as well further research.

Abstract
A number of assessment instruments have been developed as efficacy measures of geriatric depression in clinical trials but most showed several weaknesses, such as time-consuming administration, development and validation in younger populations, and lack of discrimination between anxiety and depression. Among the extant self-report measures of depression, the 21-item Teate Depression Inventory (TDI; Balsamo and Saggino, 2013), developed via Rasch analysis, showed a satisfactory level of diagnostic accuracy, and allowed the reduction of false positives in test scoring in adult population. The present study explored the potential improvement in the psychometric performance of the TDI in the elderly by item refinement through Rasch analysis in a sample of 836 elderly people (49.5% males; mean age = 73.28; SD = 6.56). A resulting shorter version was composed of the best-fitting and discriminative nine items from the full form. The Teate Depression Inventory (TDI-E) (E for elderly) presented good internal construct validity, with unidimensional structure, local dependency, good reliability (person separation index and Cronbach's alpha), and no signs of differential item functioning or measurement bias due to gender and age (65 vs. 75+ years). Cut-off points and normative data provided could enhance the clinical usefulness of the TDI-E, which seems to be a promising valid and reliable tool for the screening of geriatric depression, with less risk of finding false positives due to overlapping of depression in elderly with other comorbid conditions.

Abstract
While comorbid depression/physical health is a major clinical concern, the conventional methods of medicine make it difficult to model the complexities of this relationship. Such challenges include cataloguing multiple trends, developing multiple complex aetiological explanations, and modelling the collective large-scale dynamics of these trends. Using a case-based complexity approach, this study engaged in a richly described case study to demonstrate the utility of computational modelling for primary care research. N = 259 people were subsampled from the Diamond database, one of the largest primary care depression cohort studies worldwide. A global measure of depressive symptoms (PHQ-9) and physical health (PCS-12) were assessed at 3, 6, 9, and 12 months and then annually for a total of 7 years. Eleven trajectories and 2 large-scale collective dynamics were identified, revealing that while depression is comorbid with poor physical health, chronic illness is often low dynamic and not always linked to depression. Also, some of the cases in the unhealthy and oscillator trends remain ill without much chance of improvement. Finally, childhood abuse, partner violence, and negative life events are greater amongst unhealthy trends. Computational modelling offers a major advance for health researchers to account for the diversity of primary care patients and for developing better prognostic models for team-based interdisciplinary care.

Abstract
BACKGROUND General practitioners play a key role in the care of patients with depressive disorders. We studied the frequency and type of treatment of depressive disorders in primary care. METHODS In a cross-sectional epidemiological study on a particular day in six different regions in Germany, 253 physicians and 3563 unselected patients were asked to fill in a questionnaire assessing the diagnosis and treatment of depression. A total of 3431 usable patient data sets and 3211 sets of usable data from both the patient and the physician were subjected to further analysis. RESULTS 68.0% of the 490 patients in primary care who were classified as depressed according to the Depression Screening Questionnaire received treatment from their general practitioner or in other care settings; the probability of being treated by the general practitioner was higher for patients whose diagnosis was recognized by the general practitioner (92.8%) than for the remaining depressed patients (47.8%). On the day of data recording, 54.1% of the depressed patients were under treatment by the general practitioner and 21.2% had been referred to specialized treatment. Approximately 60% of the depressed patients were not being treated, as recommended in the guidelines, with antidepressant drugs, psychotherapy, or both. The likelihood of being treated in conformity with the guidelines depended on whether or not the general practitioner had made the diagnosis of depression (odds ratio [OR] = 7.5; 95% confidence interval = [4.9; 11.6]; p <0,001); it was also higher if the general practitioner had an additional qualification in psychotherapy (OR = 1.9; [1.1; 3.4]; p = 0.022). CONCLUSION The finding that a relevant proportion of patients with depressive disorders in primary care are inadequately treated indicates the need to improve general practitioners' ability to diagnose these conditions and determine the indication for treatment.

Abstract
OBJECTIVES Depression and other mental disorders are more prevalent among individuals living with spinal cord injury (SCI) than in the community at large, and have a strong association with quality of life. Yet little is known about the prevalence and predictors of mental disorders among U.S. military Veterans living with SCI. The primary aim of this study was to present an estimate of mental disorder point prevalence in this population. The secondary aim was to examine the relationship of mental disorders to demographics, injury characteristics, and other clinically relevant features such as impairment from mental health problems and life satisfaction. DESIGN Cross-sectional. SETTING A SCI & Disorders Center at a U.S. Veterans Affairs Medical Center. PARTICIPANTS/METHODS Administrative and medical records of 280 Veterans who attended annual comprehensive SCI evaluations were evaluated. Demographics, injury characteristics, self-reported mental and emotional functioning (i.e. SF-8 Health Survey), and clinician-determined mental disorder diagnoses were attained. RESULTS Overall, 40% of patients received at least one mental disorder diagnosis, most commonly depressive disorders (19%), posttraumatic stress disorder (12%), and substance or alcohol use disorders (11%). Several patient characteristics predicted mental disorders, including age, racial minority identity, non-traumatic SCI etiology, and incomplete (i.e. AIS D) vs. complete injury. Mental disorders were associated with greater impairment from health and mental health-related problems and less satisfaction with life. CONCLUSIONS Mental disorders are common among outpatients receiving VA specialty care for SCI. These findings highlight the importance of having adequate and effective available mental health services available for Veterans with SCI.

Abstract
Depression in later life is a significant and growing problem. Age-related differences in the type and severity of depressive disorders continue to be questioned and necessarily question differential methods of assessment and treatment strategies. A host of geropsychiatric measures have been developed for diagnostic purposes, for rating severity of depression, and monitoring treatment progress. This literature review includes the self-report depression measures commonly and currently used in geropsychological practice. Each of the included measures is considered according to its psychometric properties. In particular, information about reliability; convergent, divergent, and factorial validity evidence based on data from clinical and nonclinical samples of older adults; and availability of age-appropriate norms was provided along with the strengths and weaknesses of each measure. Results highlighted that in cognitively intact or mildly impaired patients over 65 years, the Geriatric Depression Scale and the Geriatric Depression Scale-15 currently seem to be the preferred instruments. The psychometric functioning of the Beck Depression Inventory-II and the Center for Epidemiological Studies Depression Scale, instead, is mixed in this population. Most importantly, this review may be a valuable resource for practicing clinicians and researchers who wish to develop state-of-the-science assessment strategies for clinical problems and make informed choices about which instruments best suit their purposes in older populations.

Abstract
BACKGROUND Given the poor prognosis of late-life depression, it is crucial to identify those at risk. Our objective was to construct and validate a prediction rule for an unfavourable course of late-life depression. METHODS For development and internal validation of the model, we used The Netherlands Study of Depression in Older Persons (NESDO) data. We included participants with a major depressive disorder (MDD) at baseline (n = 270; 60-90 years), assessed with the Composite International Diagnostic Interview (CIDI). For external validation of the model, we used The Netherlands Study of Depression and Anxiety (NESDA) data (n = 197; 50-66 years). The outcome was MDD after 2 years of follow-up, assessed with the CIDI. Candidate predictors concerned sociodemographics, psychopathology, physical symptoms, medication, psychological determinants, and healthcare setting. Model performance was assessed by calculating calibration and discrimination. RESULTS 111 subjects (41.1%) had MDD after 2 years of follow-up. Independent predictors of MDD after 2 years were (older) age, (early) onset of depression, severity of depression, anxiety symptoms, comorbid anxiety disorder, fatigue, and loneliness. The final model showed good calibration and reasonable discrimination (AUC of 0.75; 0.70 after external validation). The strongest individual predictor was severity of depression (AUC of 0.69; 0.68 after external validation). LIMITATIONS The model was developed and validated in The Netherlands, which could affect the cross-country generalizability. CONCLUSIONS Based on rather simple clinical indicators, it is possible to predict the 2-year course of MDD. The prediction rule can be used for monitoring MDD patients and identifying those at risk of an unfavourable outcome.

Abstract
OBJECTIVES To measure persistence and nonrecurrence of depression treatment and investigate potential risk factors. METHODS We retrospectively observed a closed cohort of insurees with new-onset depression treatment in 2007 and without most psychiatric comorbidity for 16 quarters (plus one to ascertain discontinuation). We linked inpatient/outpatient/drug-data per person and quarter. Person-quarters containing specified depression services were classified as depression-treatment-person-quarters (DTPQ). We defined longterm-DTPQ-persistence as 16 + 1 continuous DTPQ and longterm-DTPQ-nonrecurrence as 12 continuous quarters without DTPQ and used multivariate logistic regression to explore associations with these outcomes. RESULTS Within first 16 quarters, 28,348 patients' first period (total time) persisted for a mean/median 5.4/3 (8.7/8) quarters. Fourteen percent had longterm-DTPQ-persistence, associated (p < .05) with baseline hospital (odds ratio, OR = 1.80), psychotherapy/specialist-interview and antidepressants (OR = 1.81), age (years, OR = 1.03), unemployment (OR = 1.21), retirement (OR = 1.31), and insured as a dependent (OR = 1.32). Thirty-four percent had longterm-DTPQ-nonrecurrence, associated with psychotherapy/specialist-interview (OR = 1.40), antidepressants (OR = 0.54), female sex (OR = 0.84), age (years, OR = 0.99), retirement (OR = 1.18), and insured as a dependent (OR = 0.88). Women differed for episodic and not chronic treatment. CONCLUSION Treatment measures compared to survey's symptoms measures. We suggest further research on "treatment-free-time." Antidepressants(-) and psychotherapy/specialist-interview(+) were significantly associated with longterm-DTPQ-nonrecurrence. This was presumably moderated by possible short-time/low-dosage antidepressants use(-) and selective therapy assignment(+). Sample selectivity limited data misclassification.

Background Around the world, depression is both under- and overtreated. The diamond clinical prediction tool was developed to assist with appropriate treatment allocation by estimating the 3-month prognosis among people with current depressive symptoms. Delivering clinical prediction tools in a way that will enhance their uptake in routine clinical practice remains challenging; however, mobile apps show promise in this respect. To increase the likelihood that an app-delivered clinical prediction tool can be successfully incorporated into clinical practice, it is important to involve end users in the app design process. Objective The aim of the study was to maximize patient engagement in an app designed to improve treatment allocation for depression. Methods An iterative, user-centered design process was employed. Qualitative data were collected via 2 focus groups with a community sample (n=17) and 7 semistructured interviews with people with depressive symptoms. The results of the focus groups and interviews were used by the computer engineering team to modify subsequent protoypes of the app. Results Iterative development resulted in 3 prototypes and a final app. The areas requiring the most substantial changes following end-user input were related to the iconography used and the way that feedback was provided. In particular, communicating risk of future depressive symptoms proved difficult; these messages were consistently misinterpreted and negatively viewed and were ultimately removed. All participants felt positively about seeing their results summarized after completion of the clinical prediction tool, but there was a need for a personalized treatment recommendation made in conjunction with a consultation with a health professional. Conclusions User-centered design led to valuable improvements in the content and design of an app designed to improve allocation of and engagement in depression treatment. Iterative design allowed us to develop a tool that allows users to feel hope, engage in self-reflection, and motivate them to treatment. The tool is currently being evaluated in a randomized controlled trial.

Abstract
OBJECTIVE To describe the characteristics of primary care attendees with depressive symptoms who use mental health websites. METHODS 789 individuals with depressive symptoms recruited and followed up annually for nine years. Self-reported written surveys included mental health, professional and self-help use, e-mental health interventions or therapeutic websites. Marginal logistic regression examined association between mental health website (MHW) use and patient's mental health, health services use, anti-depressant use and self-help strategies. RESULTS 36% of participants used an MHW at least once. MHW users were more likely to be female, younger, highly educated and employed. MHW use increased with depressive symptom severity; reported in 16% of assessments when minimal symptoms were present and 28% when severe symptoms were present. MHW use was associated with: GP mental health visits, psychologist and psychiatrist visits and other self-help strategies including self-help books and telephone helplines. CONCLUSION(S) Mental health websites were more likely to be used by those with severe depressive symptoms rather than those with mild depression as recommended in current guidelines. PRACTICE IMPLICATION(S) Whilst mental health websites offer potential to support the high volume of people with mild depression new strategies may be required to ensure uptake.

Frem Y, Torrens M, Domingo-Salvany A, Gilchrist G. Gender differences in lifetime psychiatric and substance use disorders among people who use substances in Barcelona, Spain. ADVANCES IN DUAL DIAGNOSIS 2017.

Abstract
Purpose
The purpose of this paper is to examine gender differences in lifetime substance use and non-substance use (non-SUD) psychiatric disorders among illicit drug users and determine factors associated with non-SUD psychiatric disorders independently for males and for females.
Design/methodology/approach
Secondary analysis of five cross-sectional studies conducted in Barcelona, Spain during 2000-2006. Lifetime DSM-IV substance use and non-SUD psychiatric diagnoses were assessed using the Spanish Psychiatric Research Interview for Substance and Mental disorders (PRISM) among 629 people who use substances (68 per cent male) recruited from treatment (n=304) and out of treatment (n=325) settings. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using binary logistic regression.
Findings
The prevalence of any lifetime psychiatric (non-SUD) disorder was 41.8 per cent, with major depression (17 per cent) and antisocial personality disorder (17 per cent) being the most prevalent disorders. After adjusting for age and study, the odds of having any lifetime non-SUD (OR 2.10; 95%CI 1.48, 2.96); any mood disorder (OR 2.13; 95%CI 1.46, 3.11); any anxiety disorder (OR 1.86; 95%CI 1.19; 2.92); any eating disorder (OR 3.09; 95%CI 1.47, 6.47); or borderline personality disorder (OR 2.30; 95%CI 1.36, 3.84) were greater for females than males. Females were less likely than males to meet criteria for antisocial personality disorder (OR 0.59; 95%CI 0.36, 0.96) and attention deficit disorder (OR 0.37; 95%CI 0.17, 0.78).
Research limitations/implications
Psychiatric disorders are common among people who use substances, with gender differences reported for specific disorders. Gender-sensitive integrated treatment approaches are required to prevent and to address comorbidity psychiatric disorders among this population.
Originality/value
This secondary analysis of five cross-sectional studies included a large sample size allowing sufficient power to examine the differences between men and women. An additional strength of the methodology is the use of the gold standard PRISM which was used to assess disorders.

Abstract
AbstractBackgroundMost practice guidelines recommend maintenance antidepressant treatment for recurrent major depressive disorder. However, the degree to which such guidance is actually followed in primary health care has remained obscure. We investigated the provision of maintenance antidepressant treatment within a representative primary care five-year cohort study.MethodsIn the Vantaa Primary Care Depression Study, a stratified random sample of 1119 adult patients was screened for depression using the Prime-MD. Depressive and comorbid psychiatric disorders were diagnosed using SCID-I/P and SCID-II interviews. Of the 137 patients with depressive disorders, 82% completed the prospective five-year follow-up. A graphic life chart enabling evaluation of the longitudinal course of episodes plus duration of pharmacotherapies was used. In accordance with national guidelines, an indication for maintenance treatment was defined to exist after three or more lifetime major depressive episodes (MDEs); maintenance treatment was to commence four months after onset of full remission.ResultsOf the cohort patients, 34% (46/137) had three or more lifetime MDEs, thus indicating the requirement for maintenance pharmacotherapy. Of these, half (54%, 25/46) received maintenance treatment, for only 29% (489/1670) of the months indicated.ConclusionsIn this cohort of depressed primary care patients, half of patients with indications for maintenance treatment actually received it, and only for a fraction of the time indicated. Antidepressant maintenance treatment for the prevention of recurrences is unlikely to be subject to large-scale actualization as recommended, which may significantly undermine the potential public health benefits of treatment.

Cost-effectiveness of brexpiprazole adjunctive treatment for major depressive disorder. J Affect Disord 2017; 207:54-62.

Abstract
BACKGROUND Major depressive disorder (MDD) is a debilitating psychiatric illness with a high cost burden. This analysis evaluates the cost-effectiveness of adjunctive brexpiprazole versus comparator branded adjunctive treatment for MDD and background antidepressant therapy (ADT) alone from a US payer perspective. METHODS An economic model was developed to assess the cost-effectiveness of brexpiprazole versus comparator adjunctive treatment and ADT alone on total direct medical costs using a 6-week cycle time frame for a total of 48 weeks, with treatment response and remission as primary outcomes. The model consisted of 3 parts, 1 to represent the acute treatment phase and 2 to represent the maintenance stage. RESULTS In the base-case analysis, brexpiprazole as reference treatment resulted in cost per additional responder ranging from $19,442-$48,745 and cost per additional remitter ranging from $27,196-$71,839 versus comparator treatments over 48 weeks. Sensitivity analyses showed treatment with brexpiprazole was more costly, but more clinically effective in all probabilistic simulations. LIMITATIONS This representation of disease natural history over 48 weeks may not account for all possible health states. Resource utilization on treatment was estimated using the resource use data from previous trials, and may overestimate medical costs compared to the real-world setting. Treatment comparators were limited to branded therapies, and head-to-head studies were not available to obtain data inputs. CONCLUSION Compared to other branded adjunctive therapies, brexpiprazole increases response and remission at 6 weeks; medical care cost savings were observed with the use of brexpiprazole. These findings may assist clinicians and formulary decision makers when selecting treatment for MDD.

Abstract
OBJECTIVE Depression is pervasive and costly, and the majority of depression is treated in primary care. The objective of this study was to identify patient characteristics predictive of poor depression outcomes in primary care clinics. METHODS This observational study followed 792 patients receiving usual care for depression in 83 clinics across Minnesota for at least six months between 2008 and 2010. The primary outcome was an ordinal outcome of remission or response without remission ("response") six months after the start of treatment. The outcome was assessed via telephone administration of the Patient Health Questionnaire-9. Associations of patient characteristics with the primary outcome were assessed by using ordinal logistic regression. RESULTS The majority of patients were female, Caucasian, and employed, and most had some college education and good, very good, or excellent self-rated health. At baseline, 32% had mild depression, 40% moderate depression, 20% moderately severe depression, and 8% severe depression. One-third of patients had psychotherapy or psychiatric care in addition to antidepressant medications. At six months, only 47% of patients obtained depression remission or response. Patients were significantly less likely to experience remission or response if they rated their health as poor or fair or if they were unemployed and were more likely to achieve remission or response if they were younger or had mild depression. CONCLUSIONS Patients with poor or fair health or who were unemployed were less likely to respond to usual depression care and may be good candidates for limited, but potentially more effective, intensive treatment resources for depression.

Abstract
BACKGROUND Primary health care bears the main responsibility for treating depression in most countries. However, few studies have comprehensively investigated provision of pharmacological and psychosocial treatments, their continuity, or patient attitudes and adherence to treatment in primary care. METHODS In the Vantaa Primary Care Depression Study, 1111 consecutive primary care patients in the City of Vantaa, Finland, were screened for depression with Prime-MD, and 137 were diagnosed with DSM-IV depressive disorders via SCID-I/P and SCID-II interviews. The 100 patients with current major depressive disorder (MDD) or partly remitted MDD at baseline were prospectively followed up to 18 months, and their treatment contacts and the treatments provided were longitudinally followed. RESULTS The median number of patients' visits to a general practitioner during the follow-up was five; of those due to depression two. Antidepressant treatment was offered to 82% of patients, but only 50% commenced treatment and adhered to it adequately. Psychosocial support was offered to 49%, but only 29% adhered to the highly variable interventions. Attributed reasons for poor adherence varied, including negative attitude, side effects, practical obstacles, or no perceived need. About one-quarter (23%) of patients were referred to specialized care at some time-point. LIMITATIONS Moderate sample size. Data collected in 2002-2004. CONCLUSIONS The majority of depressive patients in primary health care had been offered pharmacotherapy, psychotherapeutic support, or both. However, effectiveness of these efforts may have been limited by lack of systematic follow-up and poor adherence to both pharmacotherapy and psychosocial treatment.

Abstract
BACKGROUND Patients with cardiovascular disease have an increased risk for depression, and depression predicts poor prognosis in these patients, but the long-term course of depression is not known. We studied the natural course of elevated levels of depressive symptoms in patients with cardiovascular disease over eight years follow-up. METHODS Within the Second Manifestations of ARTerial disease - Memory, depression and aging (SMART-Medea) study, depressive symptoms were assessed with the Patient Health Questionnaire-9 (PHQ-9) in 690 patients (62±10 years) at baseline and bi-annually during 8 years follow-up. Natural course was described for symptom severity and course type (never, single episode, intermittent, and chronic) based on the cut-off point of ≥6 on the PHQ-9. Using multinomial regression analysis (reference: never depressed) we estimated age- and sex-adjusted odds ratios (OR) for the associations of demographic factors and vascular disease categories with course type. RESULTS Of the 690 patients, 60% was never depressed, 10% had a single episode, 19% had an intermittent and 11% a chronic course of depression. Increased risk for chronic course was observed for women (OR=3.42; 95% CI=1.98-5.90), those with younger age (OR=3.20; 95% CI=1.73-5.94), and for patients with cerebrovascular disease when compared to patients with coronary artery disease (OR=2.50; 95% CI=1.31-4.78). LIMITATIONS No information was available on clinical diagnosed major depressive disorder and/or clinical events during follow-up. CONCLUSIONS In patients with cardiovascular disease, an intermittent or chronic course of elevated levels of depressive symptoms is very common. Patients with cardiovascular disease may require more careful clinical monitoring and management of depressive symptoms.

Abstract
BACKGROUND Routine outcome monitoring of common mental health disorders (CMHDs), using patient reported outcome measures (PROMs), has been promoted across primary care, psychological therapy and multidisciplinary mental health care settings, but is likely to be costly, given the high prevalence of CMHDs. There has been no systematic review of the use of PROMs in routine outcome monitoring of CMHDs across these three settings. OBJECTIVES To assess the effects of routine measurement and feedback of the results of PROMs during the management of CMHDs in 1) improving the outcome of CMHDs; and 2) in changing the management of CMHDs. SEARCH METHODS We searched the Cochrane Depression Anxiety and Neurosis group specialised controlled trials register (CCDANCTR-Studies and CCDANCTR-References), the Oxford University PROMS Bibliography (2002-5), Ovid PsycINFO, Web of Science, The Cochrane Library, and International trial registries, initially to 30 May 2014, and updated to 18 May 2015. SELECTION CRITERIA We selected cluster and individually randomised controlled trials (RCTs) including participants with CMHDs aged 18 years and over, in which the results of PROMs were fed back to treating clinicians, or both clinicians and patients. We excluded RCTs in child and adolescent treatment settings, and those in which more than 10% of participants had diagnoses of eating disorders, psychoses, substance use disorders, learning disorders or dementia. DATA COLLECTION AND ANALYSIS At least two authors independently identified eligible trials, assessed trial quality, and extracted data. We conducted meta-analysis across studies, pooling outcome measures which were sufficiently similar to each other to justify pooling. MAIN RESULTS We included 17 studies involving 8787 participants: nine in multidisciplinary mental health care, six in psychological therapy settings, and two in primary care. Pooling of outcome data to provide a summary estimate of effect across studies was possible only for those studies using the compound Outcome Questionnaire (OQ-45) or Outcome Rating System (ORS) PROMs, which were all conducted in multidisciplinary mental health care or psychological therapy settings, because both primary care studies identified used single symptom outcome measures, which were not directly comparable to the OQ-45 or ORS.Meta-analysis of 12 studies including 3696 participants using these PROMs found no evidence of a difference in outcome in terms of symptoms, between feedback and no-feedback groups (standardised mean difference (SMD) -0.07, 95% confidence interval (CI) -0.16 to 0.01; P value = 0.10). The evidence for this comparison was graded as low quality however, as all included studies were considered at high risk of bias, in most cases due to inadequate blinding of assessors and significant attrition at follow-up.Quality of life was reported in only two studies, social functioning in one, and costs in none. Information on adverse events (thoughts of self-harm or suicide) was collected in one study, but differences between arms were not reported.It was not possible to pool data on changes in drug treatment or referrals as only two studies reported these. Meta-analysis of seven studies including 2608 participants found no evidence of a difference in management of CMHDs between feedback and no-feedback groups, in terms of the number of treatment sessions received (mean difference (MD) -0.02 sessions, 95% CI -0.42 to 0.39; P value = 0.93). However, the evidence for this comparison was also graded as low quality. AUTHORS' CONCLUSIONS We found insufficient evidence to support the use of routine outcome monitoring using PROMs in the treatment of CMHDs, in terms of improving patient outcomes or in improving management. The findings are subject to considerable uncertainty however, due to the high risk of bias in the large majority of trials meeting the inclusion criteria, which means further research is very likely to have an important impact on the estimate of effect and is likely to change the estimate. More research of better quality is therefore required, particularly in primary care where most CMHDs are treated.Future research should address issues of blinding of assessors and attrition, and measure a range of relevant symptom outcomes, as well as possible harmful effects of monitoring, health-related quality of life, social functioning, and costs. Studies should include people treated with drugs as well as psychological therapies, and should follow them up for longer than six months.

Abstract
Background The naturalistic course for patients suffering from depressive disorders can be quite varied. Whilst some remit with little or no intervention, others may suffer a more prolonged course of symptoms. The aim of this study was to identify trajectory patterns for depressive symptoms in a Chinese primary care cohort and their associated factors. Methods and Results A 12-month cohort study was conducted. Patients recruited from 59 primary care clinics across Hong Kong were screened for depressive symptoms using the Centre for Epidemiologic Studies Depression Scale (CES-D) and monitored over 12 months using the Patient Health Questionnaire-9 items (PHQ-9) administered at 12, 26 and 52 weeks. 721 subjects were included for growth mixture modelling analysis. Using Akaike Information Criterion, Bayesian Information Criterion, Entropy and Lo-Mendell-Rubin adjusted likelihood ratio test, a seven-class trajectory path model was identified. Over 12 months, three trajectory groups showed improvement in depressive symptoms, three remained static, whilst one deteriorated. A mild severity of depressive symptoms with gradual improvement was the most prevalent trajectory identified. Multivariate, multinomial regression analysis was used to identify factors associated with each trajectory. Risk factors associated with chronicity included: female gender; not married; not in active employment; presence of multiple chronic disease co-morbidities; poor self-rated general health; and infrequent health service use. Conclusions Whilst many primary care patients may initially present with a similar severity of depressive symptoms, their course over 12 months can be quite heterogeneous. Although most primary care patients improve naturalistically over 12 months, many do not remit and it is important for doctors to be able to identify those who are at risk of chronicity. Regular follow-up and greater treatment attention is recommended for patients at risk of chronicity.

Abstract
Background: The association between depression, anxiety, and stress among Arab menopause and postmenopausal women have been explored in detailed. Aim: The objective of this study was to determine the correlation between depression, anxiety, and stress in menopausal and postmenopausal women and shedding more light on a complex relationship. Subjects and Methods: A cross-sectional descriptive study was used to generate menopause symptoms experienced by Arabian women at the primary health care centers in Qatar. A representative sample of 1468 women aged 45–65 years were approached during July 2012 and May 2014 and 1101 women agreed to participate (75.0%) and responded to the study. Depression, anxiety, and stress were measured using the Depression Anxiety Stress Scales 21. Data on body mass index (BMI), clinical and other parameters were used. Univariate, multivariate, and matrix correlation analysis were performed for statistical analysis. Results: A total of 1101 women agreed to participate after informed consent was obtained. The mean age and standard deviation (SD) of the menopausal age were 49.55 (3.12), the mean and SD of postmenopausal age was 58.08 (3.26) (P < 0.001). There were statistically significant differences between menopausal stages with regards to age, ethnicity, educational status, occupation status, and place of living. Furthermore, there were statistically significant differences between menopausal stages with regards to BMI, systolic and diastolic blood pressure (BP), Vitamin D deficiency, and diseases. Depression and anxiety were more common among postmenopause women. Furthermore, there were no differences between the groups regarding the frequency of certain levels of stress among menopause and postmenopause. The multivariate regression analyses revealed that age in years, diastolic BP, consanguinity, regular exercise were a predictor for depression. Meanwhile, diastolic BP, occupation, and physical activity considered the main risk factors for anxiety. Furthermore, age in years, occupation, and sheesha smoking habits were considered as the main risk factors associated with stress. Conclusion: A large number of factors were associated with experiencing menopausal and psycho-social problems and which had negative effects on the quality of life among Arabian women. Depression, anxiety, and stress should be considered as important risk factors for osteoporosis.

Predictors of Response to Web-Based Cognitive Behavioral Therapy With High-Intensity Face-to-Face Therapist Guidance for Depression: A Bayesian Analysis. J Med Internet Res 2015; 17:e197.

Abstract
Background Several studies have demonstrated the effect of guided Internet-based cognitive behavioral therapy (ICBT) for depression. However, ICBT is not suitable for all depressed patients and there is a considerable level of nonresponse. Research on predictors and moderators of outcome in ICBT is inconclusive. Objective This paper explored predictors of response to an intervention combining the Web-based program MoodGYM and face-to-face therapist guidance in a sample of primary care patients with mild to moderate depressive symptoms. Methods Participants (N=106) aged between 18 and 65 years were recruited from primary care and randomly allocated to a treatment condition or to a delayed treatment condition. The intervention included the Norwegian version of the MoodGYM program, face-to-face guidance from a psychologist, and reminder emails. In this paper, data from the treatment phase of the 2 groups was merged to increase the sample size (n=82). Outcome was improvement in depressive symptoms during treatment as assessed with the Beck Depression Inventory-II (BDI-II). Predictors included demographic variables, severity variables (eg, number of depressive episodes and pretreatment depression and anxiety severity), cognitive variables (eg, dysfunctional thinking), module completion, and treatment expectancy and motivation. Using Bayesian analysis, predictors of response were explored with a latent-class approach and by analyzing whether predictors affected the slope of response. Results A 2-class model distinguished well between responders (74%, 61/82) and nonresponders (26%, 21/82). Our results indicate that having had more depressive episodes, being married or cohabiting, and scoring higher on a measure of life satisfaction had high odds for positively affecting the probability of response. Higher levels of dysfunctional thinking had high odds for a negative effect on the probability of responding. Prediction of the slope of response yielded largely similar results. Bayes factors indicated substantial evidence that being married or cohabiting predicted a more positive treatment response. The effects of life satisfaction and number of depressive episodes were more uncertain. There was substantial evidence that several variables were unrelated to treatment response, including gender, age, and pretreatment symptoms of depression and anxiety. Conclusions Treatment response to ICBT with face-to-face guidance may be comparable across varying levels of depressive severity and irrespective of the presence and severity of comorbid anxiety. Being married or cohabiting, reporting higher life satisfaction, and having had more depressive episodes may predict a more favorable response, whereas higher levels of dysfunctional thinking may be a predictor of poorer response. More studies exploring predictors and moderators of Internet-based treatments are needed to inform for whom this treatment is most effective.

Abstract
This study examined predictors of persistent major depressive disorder over 10 years, focusing on the effects of clinical variables, physical health, and social support. Data from the National Survey of Midlife Development in the United States in 1995-1996 and 2004-2006 were analyzed. Logistic regression was used to predict non-recovery from major depression among individuals who met clinical-based criteria for major depressive disorder at baseline. Fifteen percent of the total sample was classified as having major depression in 1995-1996; of these individuals, 37 % had major depression in 2004-2006. Baseline variables that were significantly associated with persistent major depression at follow-up were being female, having never married, having two or more chronic medical conditions, experiencing activity limitation, and less contact with family. Therefore, treatment strategies focused on physical health, social support, and mental health needs are necessary to comprehensively address the factors that contribute to persistent major depressive disorder.

Abstract
BACKGROUND Subthreshold depression is prevalent in primary care and is associated with poorer quality of life, higher health care use and increased risk of major depressive disorder (MDD). Currently, it is unclear how subthreshold depression should be managed in primary care and no studies have investigated the relationship between current models of care and the development of MDD. This study aimed to describe usual care over a six month follow-up for primary care patients with subthreshold depression and to investigate the relationship between usual care and the development of MDD. METHODS Data were derived from 250 participants with subthreshold depression from the diamond study, a longitudinal cohort study of primary care patients. Participants completed questionnaires at three and six months on their health care use, the interventions they received and their depression status. Interventions were categorised according to the NICE guidelines for the management of depression in adults. Generalised estimating equation (GEE) models and logistic regression were used to estimate the association between receiving an intervention and MDD over six months. RESULTS Four fifths (80.8%) of participants received a mental health intervention. Therapeutic listening, reassurance, pharmacotherapy and advice to exercise were most common. Subsequent MDD was predicted by history of depression, baseline depressive symptom severity and receiving a mental health intervention. LIMITATIONS Usual care was assessed via patient self-report. CONCLUSIONS Primary care physicians deliver mental health interventions to most subthreshold patients. However, it appears that current interventions are not averting MDD. Further research to identify effective interventions which are feasible in primary care is needed.

Abstract
Background While depression is frequently managed by general practitioners, often patients self-manage these symptoms with alternative therapies, including St John’s wort (SJW). We tested whether use of SJW was associated with different patterns of conventional and complementary health service use, strategies used for management of depression, or user dissatisfaction with or lack of trust in their general practitioner or clinic overall. Methods Secondary analysis of data collected from an Australian population screened for a longitudinal cohort study of depression. Main outcome measures were CES-D for depressive symptoms, satisfaction with their general practitioner (GPAQ), Trust in Physician scale, self-report of health services usage and strategies used to manage depression, stress or worries. Results Response rate was 7667/17,780 (43.1%). Of these, 4.3% (320/7,432) had used SJW in the past 12 months (recent ‘SJW users’). SJW users were significantly more likely to be depressed and to have a higher CES-D score. There were no statistically significant differences between recent SJW users and non-SJW users in satisfaction with their general practice or in trust in their general practitioner (GP) when adjusted for multiple factors. SJW users were significantly more likely to use all health services, whether conventional or complementary, as well as other strategies used for mental health care. SJW users were also more likely to consider themselves the main carer for their depression. Conclusions Primary care attendees with symptoms of depression who use SJW appear not to be rejecting conventional medicine. Rather, they may be proactive care seekers who try both conventional and complementary strategies to manage their depressive symptoms. If GPs enquire and find that their depressed patients are using SJW, this may indicate that they might explore for unrelieved symptoms of depression and also consider the issue of potential for interactions between SJW and other medicines.

Abstract
BACKGROUND Intimate partner violence (IPV) is yet to be fully acknowledged as a public health problem in Slovenia. This study aimed to explore the health and other patient characteristics associated with psychological IPV exposure and gender-related specificity in family clinic attendees. METHODS In a multi-centre cross-sectional study, 960 family practice attendees aged 18 years and above were recruited. In 689 interviews with currently- or previously-partnered patients, the short form of A Domestic Violence Exposure Questionnaire and additional questions about behavioural patterns of exposure to psychological abuse in the past year were given. General practitioners (GPs) reviewed the medical charts of 470 patients who met the IPV exposure criteria. The Domestic Violence Exposure Medical Chart Check List was used, collecting data on the patients' lives and physical, sexual and reproductive, and psychological health status, as well as sick leave, hospitalisation, visits to family practices and referrals to other clinical specialists in the past year. In multivariate logistic regression modelling the factors associated with past year psychological IPV exposure were identified, with P<0.05 set as the level of statistical significance. RESULTS Of the participants (n=470), 12.1% (n=57) were exposed to psychological IPV in the previous year (46 women and 11 men). They expressed more complaints regarding sexual and reproductive (p=0.011), and psychological and behavioural status (p<0.001), in the year prior to the survey. Unemployment or working part-time, a college degree, an intimate relationship of six years or more and a history of disputes in the intimate relationship, increased the odds of psychological IPV exposure in the sample, explaining 41% of the variance. In females, unemployment and a history of disputes in the intimate relationship explained 43% of the variance. CONCLUSIONS The prevalence of psychological IPV above 10% during the past year was similar to earlier studies in Slovenia, although the predominance of better-educated people might be associated with lower tolerance toward psychological abuse. GPs should pay special attention to unemployed patients and those complaining about family disputes, to increase early detection.

Core discrete event simulation model for the evaluation of health care technologies in major depressive disorder.

Abstract
OBJECTIVE A review of existing economic models in major depressive disorder (MDD) highlighted the need for models with longer time horizons that also account for heterogeneity in treatment pathways between patients. A core discrete event simulation model was developed to estimate health and cost outcomes associated with alternative treatment strategies. METHODS This model simulated short- and long-term clinical events (partial response, remission, relapse, recovery, and recurrence), adverse events, and treatment changes (titration, switch, addition, and discontinuation) over up to 5 years. Several treatment pathways were defined on the basis of fictitious antidepressants with three levels of efficacy, tolerability, and price (low, medium, and high) from first line to third line. The model was populated with input data from the literature for the UK setting. Model outputs include time in different health states, quality-adjusted life-years (QALYs), and costs from National Health Service and societal perspectives. The codes are open source. RESULTS Predicted costs and QALYs from this model are within the range of results from previous economic evaluations. The largest cost components from the payer perspective were physician visits and hospitalizations. Key parameters driving the predicted costs and QALYs were utility values, effectiveness, and frequency of physician visits. Differences in QALYs and costs between two strategies with different effectiveness increased approximately twofold when the time horizon increased from 1 to 5 years. CONCLUSION The discrete event simulation model can provide a more comprehensive evaluation of different therapeutic options in MDD, compared with existing Markov models, and can be used to compare a wide range of health care technologies in various groups of patients with MDD.

Abstract
OBJECTIVE "Patient activation" describes the extent to which individuals manage their own healthcare. This study evaluated the association of patient activation, depressive symptoms and quality of life in a primary care setting. METHODS 278 patients who visited two primary care clinics were interviewed in the waiting room before their appointment or by telephone. Study participants completed the Patient Activation Measure (PAM), Patient Health Questionnaire-9 (PHQ-9) and Short Form-12 Health Survey (SF-12). Physicians assessed each participant's depression status immediately after the visit. RESULTS PAM scores correlated negatively with PHQ-9 (r=-0.35, p<0.0001) and positively with total SF-12 score (r=0.39, p<0.0001). Increased participant involvement by one-level increments on the PAM was predicted by their being in the 55 to 74-year age group and higher total SF-12 quartiles. Almost half of those scoring ≥10 on PHQ-9 were not considered depressed by their physician (false negatives, i.e. "hidden depression"). CONCLUSION In primary care settings, PAM is easily administered and useful for general patients and for those with depressive symptoms. PRACTICE IMPLICATIONS Assessing patient activation will enable caregivers to monitor levels of self-care (activation) and potential adherence to health behavior recommendations. PHQ-9 screening could increase awareness of "hidden depression" in the primary care setting.

Abstract
Background Major depression is a commonly occurring, seriously impairing, and often recurrent mental disorder. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are the treatments most commonly used for major depressive disorder. The objective of this study was to assess the cost-effectiveness of SSRIs and SNRIs in the treatment of major depressive disorder in two Italian regional settings, ie, Veneto and Sardinia. Methods A decision analytic model was adapted from the Swedish Dental and Pharmaceutical Benefits Agency to reflect current clinical practice in the treatment of major depressive disorder in the most significant Italian regions. This adaptation was possible as a result of collaboration with an expert panel of Italian psychiatrists and health economists. The population comprised patients with a first diagnosis of major depressive disorder and initiating one SSRI or SNRI drug for the first time. The time frame used was 12 months. Efficacy and utility data for the model were retrieved from the literature and validated by the expert panel. Local data were used for resource utilization and for treatment costs based on the perspective of each regional health service. Scenario analyses and probabilistic sensitivity analyses were performed to test the robustness of the model. Results Base case analysis showed that escitalopram is associated with the largest health gain (in quality-adjusted life years) and a lower total cost at one year for Sardinia (except for sertraline, against which it was cost-effective) and for Veneto, and therefore dominates the other treatment strategies, given that more quality-adjusted life years are achieved at a lower total cost. Scenario analyses and probabilistic sensitivity analyses support the robustness of the model. Conclusion The results indicate that escitalopram is the most cost-effective pharmacologic treatment strategy for both regional health services compared with all SSRIs and all SNRIs used in the first-line treatment of major depressive disorder.

Abstract
PURPOSE To determine whether social support and/or physical activity buffer the association between stressors and increasing risk of depression symptoms at baseline and at 3-year follow-up. METHODS This is a secondary analysis of data from the Women's Health Initiative Observational Study. 91,912 community-dwelling post-menopausal women participated in this prospective cohort study. Depression symptoms were measured at baseline and 3 years later; social support, physical activity, and stressors were measured at baseline. RESULTS Stressors at baseline, including verbal abuse, physical abuse, caregiving, social strain, negative life events, financial stress, low income, acute pain, and a greater number of chronic medical conditions, were all associated with higher levels of depression symptoms at baseline and new onset elevated symptoms at 3-year follow-up. Social support and physical activity were associated with lower levels of depressive symptoms. Contrary to expectation, more social support at baseline strengthened the association between concurrent depression and physical abuse, social strain, caregiving, and low income. Similarly, more social support at baseline increased the association between financial stress, income, and pain on new onset depression 3 years later. Physical activity similarly moderated the effect of caregiving, income, and pain on depression symptoms at baseline. CONCLUSION Stressors, social support, and physical activity showed predicted main effect associations with depression. Multiplicative interactions were small in magnitude and in the opposite direction of what was expected.

Abstract
INTRODUCTION Depression is common, disabling, and the single most important factor leading to suicide, yet it is underdiagnosed in busy primary care settings. A key challenge facing primary care clinicians in Asia is the selection of instruments to facilitate depression screening. Although the nine-item Patient Health Questionnaire (PHQ-9) and 16-item Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR16 ) are used internationally, they have not been directly compared or widely validated in Asian primary care populations. This study aimed to validate the PHQ-9 and QIDS-SR16 against a structured interview diagnosis of Diagnostic and Statistical Manual, 4th Edition, depression based on the Mini-International Neuropsychiatric Interview in a multiethnic Asian sample. METHODS From April through August 2011, we enrolled 400 English-speaking Singaporean primary care patients. Participants completed a demographic data form, the PHQ-9, and the QIDS-SR16 . They were assessed independently for major and minor depression using the Mini-International Neuropsychiatric Interview. RESULTS Sensitivity and specificity for diagnosing major depression were 91.7% and 72.2%, respectively, for the PHQ-9 (optimal cutoff score of 6), and 83.3% and 84.7%, respectively, for the QIDS-SR16 (optimal cutoff score of 9). The QIDS-SR16 also detected minor depression at an optimal cutoff score of 7, with a sensitivity of 94.4% and specificity of 77.9%. The PHQ-9 and QIDS-SR16 showed good internal consistency (Cronbach's α: 0.87 and 0.79, respectively) and good convergent validity (correlation coefficient: r = 0.73, P < 0.001). The overall prevalence of major and minor depressive disorders was 9%. DISCUSSION The PHQ-9 and QIDS-SR16 appear to be valid and reliable for depression screening in Asian primary care settings.

C-QUALITY: cost and quality-of-life pharmacoeconomic analysis of antidepressants in major depressive disorder in Italy. Adv Ther 2013; 30:697-712.

Abstract
INTRODUCTION Major depressive disorder (MDD) is a common and disabling condition across the world. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are the most commonly used antidepressants. The objective of this study was to assess the cost-effectiveness [€ per quality-adjusted life year (QALY)] of all SSRIs and all SNRIs for the treatment of MDD in Italy. METHODS A decision analytic model was adapted from the Swedish Dental and Pharmaceutical Benefits agency model to reflect current clinical practice in the treatment of MDD in the largest Italian regions. This adaptation was possible thanks to the collaboration of an expert panel of Italian psychiatrists and health economists. The model evaluated patients with a first diagnosis of MDD and initiating an SSRI or an SNRI for the first time. The time horizon was 12 months. Efficacy and utility data for the model were retrieved from the literature and validated by the expert panel. Local data were considered for resource utilization and for treatment costs based on each regional health service perspective. Population-weighted regional data were used to define a national model. Scenario simulations, one-way sensitivity analyses, and Monte Carlo simulations were performed to test the robustness of the model. RESULTS The base case analysis showed that escitalopram was associated with a lower total cost (€ 1,562) and a larger health gain (QALYs) at 1 year (0.732) per patient and dominated the other treatment strategies since more QALYs were achieved at a lower total cost. Sensitivity analyses support the robustness of the model. CONCLUSION The results indicate that escitalopram is the most cost-effective pharmacological treatment strategy for the Italian health service compared with other SSRIs and all SNRIs used in the first-line treatment of MDD.

Abstract
PURPOSE Major depressive disorder may vary according to number and duration of episodes. It is unclear whether risk factors for onset of multiple or long episodes of depression (MDE) differ from risk factors for the onset of single and short ones. METHODS Data were used from a cohort study of 5,256 GP attendees without major depressive disorder at baseline, who were followed up three times (predictD). The numbers and duration of MDE were noted and categorized into no episodes, single and short (≤3 months), and multiple or long (>3 months) episodes at follow-up. Log-binomial regression models were used to calculate relative risks between the groups for 18 risk factors examined at baseline. RESULTS 165 persons (3 %) had a single and short MDE and 328 (6 %) had multiple or long MDE at follow-up. Lower education, anxiety, problems at work and financial strain significantly increased the risk of multiple or long MDE when compared to single and short MDE. Younger people were at reduced risk of multiple or long MDE. CONCLUSIONS Our findings suggest that several risk factors can be identified that may help to predict onset of different types of MDE. These factors are easy to assess and may be used in the prevention of depression.

Abstract
BACKGROUND Depression screening in primary care yields high numbers. Knowledge of how depressive symptoms change over time is limited, making decisions about type, intensity, frequency and length of treatment and follow-up difficult. This study is aimed to identify depressive symptom trajectories and associated socio-demographic, co-morbidity, health service use and treatment factors to inform clinical care. METHODS 789 people scoring 16 or more on the CES-D recruited from 30 randomly selected Australian family practices. Depressive symptoms are measured using PHQ-9 at 3, 6, 9 and 12 months. RESULTS Growth mixture modelling identified a five-class trajectory model as the best fitting (lowest Bayesian Information Criterion): three groups were static (mild (n=532), moderate (n=138) and severe (n=69)) and two were dynamic (decreasing severity (n=32) and increasing severity (n=18)). The mild symptom trajectory was the most common (n=532). The severe symptom trajectory group (n=69) differed significantly from the mild symptom trajectory group on most variables. The severe and moderate groups were characterised by high levels of disadvantage, abuse, morbidity and disability. Decreasing and increasing severity trajectory classes were similar on most variables. LIMITATIONS Adult only cohort, self-report measures. CONCLUSIONS Most symptom trajectories remained static, suggesting that depression, as it presents in primary care, is not always an episodic disorder. The findings indicate future directions for building prognostic models to distinguish those who are likely to have a mild course from those who are likely to follow more severe trajectories. Determining appropriate clinical responses based upon a likely depression course requires further research.

Abstract
OBJECTIVE Examine time to recurrence of major depressive disorder (MDD) across different treatment settings and assess predictors of time to recurrence of MDD. METHODS Data were from 375 subjects with a MDD diagnosis from the Netherlands Study of Depression and Anxiety (NESDA). The study sample was restricted to subjects with a remission of at least three months. These subjects were followed until recurrence or the end of the two year follow-up. DSM-IV based diagnostic interviews and Life Chart Interviews were used to assess time to recurrence of MDD across treatment settings. Predictors of time to recurrence were determined using Cox's proportional hazards analyses. RESULTS Although trends indicated a slightly higher rate of and shorter time to recurrence in specialized mental health care, no significant difference in recurrence rate (26.8% versus 33.5%, p=0.23) or in time to recurrence (controlled for covariates) of MDD was found between respondents in specialized mental health care and respondents treated in primary care (average 6.6 versus 5.5 months, p=0.09). In multivariable analyses, a family history of MDD and previous major depressive episodes were associated with a shorter time to recurrence. Predictors did not differ across treatment settings. LIMITATIONS The study sample may not be representative of the entire population treated for MDD in specialized mental health care. CONCLUSIONS Health care professionals in both settings should be aware of the same risk factors since the recurrence risk and its predictors appeared to be similar across settings.

Abstract
Background Depression has a lifetime prevalence of 10%–25% among women and 5%–12% among men. Selective serotonin reuptake inhibitors (SSRIs) are the most used and the most cost-effective treatment for long-term major depressive disorder. Since the introduction of generic SSRIs, the costs of branded drugs have been questioned. The objective of this study was to assess the cost-effectiveness (€ per quality-adjusted life year [QALY]) of escitalopram (which is still covered by a patent) compared with paroxetine, sertraline, and citalopram, the patents for which have expired. Methods A decision analytic model was adapted from the Swedish Dental and Pharmaceutical benefits agency model to reflect current clinical practice in the treatment of depression in Italy in collaboration with an expert panel of Italian psychiatrists and health economists. The population comprised patients with a first diagnosis of major depressive disorder and receiving for the first time one of the following SSRIs: escitalopram, sertraline, paroxetine, and citalopram. The time frame used was 12 months. Efficacy and utility data for the original model were validated by our expert panel. Local data were considered for resource utilization and for treatment costs based on the Lombardy region health service perspective. Several scenario simulations, oneway sensitivity analyses, and Monte Carlo simulations were performed to test the robustness of the model. Results The base case scenario showed that escitalopram had an incremental cost-effectiveness ratio (ICER) of €4395 and €1080 per QALY compared with sertraline and paroxetine, respectively. Escitalopram was dominant over citalopram, which was confirmed by most one-way sensitivity analyses. The escitalopram strategy gained 0.011 QALYs more than citalopram, 0.008 more than paroxetine, and around 0.007 more than sertraline. Monte Carlo simulations indicated that ICER values for escitalopram were centered around €1100 and €4400 per QALY compared with paroxetine and sertraline, respectively. Although there is no official cost-effectiveness threshold in Italy, the value of €25,000 per QALY could be acceptable. All ICER values retrieved in all analyses were lower than this threshold. Conclusion The findings from this cost-effectiveness analysis indicate that escitalopram could be accepted as a cost-effective strategy for the Lombardy region health service compared with the other SSRIs studied. The present assessment is based on ICER values resulting from this analysis, which are lower than the thresholds proposed by health care authorities in other European Union countries. These benefits are driven by the effectiveness of escitalopram, which result in an improved health-related quality of life, a higher probability of sustained remission, and better utilization of health care resources. The study results are robust and in line with other pharmacoeconomic analyses comparing escitalopram with other SSRIs.

Abstract
BACKGROUND Despite its public health significance, data about depression in general practice are often unavailable or incomplete. OBJECTIVE To study half-year follow-up data on patients diagnosed by their GP with a new episode of mild or a first episode of moderate depression, specifically: (i) treatment continuation, (ii) remission and, in ongoing episodes, suicidal behaviour and inability to work and (iii) the match between treatments initiated and delivered as well as the determinants of actual delivery of non-pharmacological support initiated by the GP for patients with ongoing depression. METHODS General practice-based data were collected on all patients aged ≥18 years who were diagnosed by their GP with a new episode of depression in Belgian sentinel general practices during 2008. RESULTS Follow-up data were available for 900 of 1048 patients. Complete treatment dropout was found in 9%, treatment discontinuation in 40% and a GP visit ≤8 weeks preceding the follow-up in 51%. Of the latter 457 patients, 60% were still depressed. Among these, one suicide attempt was reported and 24% were unable to work for ≥1 month. While 91% of the patients who received psychoactive agents at diagnosis had actually taken them, and 62% of the referred patients actually received treatment from another caregiver, non-pharmacological support by the GP was delivered in only 43% of patients for whom it was initiated. CONCLUSIONS Half a year after diagnosis, half of patients continue to visit their GP and 60% of those patients remain depressed. The delivery of non-pharmacological GP support takes place for less than half of the patients for whom that intervention is initiated. Our follow-up findings reinforce the policy recommendations made by stakeholders, i.e. the introduction and reimbursement of a mental health consultation in family practice and integration of primary care psychologists. Quality improvement interventions may be a strategy to overcome premature discontinuation of non-pharmacological support by GPs.

Abstract
OBJECTIVES To describe health-related quality of life (HRQoL), pain, clinical outcomes and treatment patterns in French patients with depression treated by general practitioners and psychiatrists. METHODS Factors Influencing Depression Endpoints Research (FINDER) is a European longitudinal observational, naturalistic, multicentre study to determine the HRQoL (SF-36 and EQ-5D) and to assess outcomes of depression and anxiety (Hospital Anxiety and Depression Scale [HADS]), and pain (VAS) in a population of depressed patients initiating antidepressant treatment. Clinical diagnosis of depression was based on physician's clinical judgment. Physicians decided at their own discretion and clinical practice to initiate pharmacological treatment for depression. Adult patients with a first or new episode of depression were enrolled between May 2004 and September 2005, and followed up for 6 months. Across Europe, 437 physicians observed 3468 patients. RESULTS In France, 606 patients (approximately 17% of the whole sample) were enrolled by 57 psychiatrists and 46 general practitioners. These patients were (mean ± SD) 45.6 ± 13.0 years old, 69% female and 39% having had a previous depressive episode in the last 2 years. According to the patient-rated HADS score greater or equal to 11, most patients (75%) were classified as cases of depression as well as cases of anxiety (84%); 51% of patients rated their overall pain severity (based on VAS cut-off of 30 mm) as moderate/severe, with 65% of these patients reporting no medical explanation for their pain. The majority (81%) of the patients were prescribed selective serotonin reuptake inhibitors (SSRI). During the 6-month follow-up, the majority of the patients (73%) remained on the same antidepressant at the same dose during the course of treatment. Between baseline and 6-month endpoint, French patients improved their mean scores (SD) on the SF-36 physical score by+3.5 (9.0) (P<0.001) and mental score by+20.6 (14.2) (P<0.001); on the EQ-5D Health State Index by+0.37 (0.32) (P<0.001) and the EQ-5D VAS by+32.3 (25.0) (P<0.001); on the HADS depression score by-8.1 (6.0) (P<0.001) and HADS anxiety score by-6.9 (5.0) (P<0.001). Patients with moderate/severe pain at baseline improved their overall pain on a mean VAS score by-34.1 (28.7) (P<0.001). CONCLUSIONS More than half of the French patients enrolled in the study experienced pain associated with depression. During follow-up, patients improved all of their outcome measurements (physical and mental SF-36 scores, depression and anxiety HADS scores, pain VAS, EQ-5D Health State Index and VAS) and most patients remained on the same antidepressant at the same dose.

Abstract
BACKGROUND Anxiety disorders are the most common mental health problems and often co-exist with substance use. Little evidence exists to support the use of brief screening tools for anxiety disorders in routine addictions treatment. This is the first study to test the validity and reliability of GAD-7 and GAD-2 in an outpatient drugs treatment population. METHODS A sample of 103 patients completed brief screening questionnaires and took part in structured diagnostic assessments using CIS-R. A subgroup of 60 patients completed retests after 4 weeks. The results of brief questionnaires were compared to those of gold-standard diagnostic interviews using Receiver Operating Characteristic (ROC) curves. Psychometric properties were also calculated to evaluate the validity and reliability of self-completed questionnaires. RESULTS A GAD-7 score ≥ 9 had a sensitivity of 80% and specificity of 86% for any anxiety disorder, also displaying adequate temporal stability at repeated measurements (intra-class correlation=0.85) and high internal consistency (Cronbach's alpha=0.91). A GAD-2 score ≥ 2 had 94% sensitivity and 53% specificity, with adequate internal consistency (0.82). CONCLUSIONS GAD-7 adequately detected the presence of an anxiety disorder in drug and alcohol users; although this study was limited by sample size to determine its reliability for specific diagnoses. Results in this small sample suggest that GAD-7 may be a useful screening tool in addiction services, although replication in a larger sample is warranted.

Abstract
OBJECTIVE To determine effectiveness and cost-effectiveness over a one-year time horizon of pharmacological first line treatment in primary care for patients with moderate to severe depression. DESIGN A multiple treatment comparison meta-analysis was employed to determine the relative efficacy in terms of remission of 10 antidepressants (citalopram, duloxetine escitalopram, fluoxetine, fluvoxamine mirtazapine, paroxetine, reboxetine, sertraline and venlafaxine). The estimated remission rates were then applied in a decision-analytic model in order to estimate costs and quality of life with different treatments at one year. DATA SOURCES Meta-analyses of remission rates from randomised controlled trials, and cost and quality-of-life data from published sources. RESULTS The most favourable pharmacological treatment in terms of remission was escitalopram with an 8- to 12-week probability of remission of 0.47. Despite a high acquisition cost, this clinical effectiveness translated into escitalopram being both more effective and having a lower total cost than all other comparators from a societal perspective. From a healthcare perspective, the cost per QALY of escitalopram was €3732 compared with venlafaxine. CONCLUSION Of the investigated antidepressants, escitalopram has the highest probability of remission and is the most effective and cost-effective pharmacological treatment in a primary care setting, when evaluated over a one year time-horizon. Small differences in remission rates may be important when assessing costs and cost-effectiveness of antidepressants.

Abstract
PURPOSE To assess the link between multimorbidity, type of chronic physical health problems and depressive symptoms METHOD The study was a cross-sectional postal survey conducted in 30 General Practices in Victoria, Australia as part of the diamond longitudinal study. Participants included 7,620 primary care attendees; 66% were females; age range from 18 to 76 years (mean = 51 years SD = 14); 81% were born in Australia; 64% were married and 67% lived in an urban area. The main outcome measures include the Centre for Epidemiologic Studies Depression Scale (CES-D) and a study-specific self-report check list of 12 common chronic physical health problems. RESULTS The prevalence of probable depression increased with increasing number of chronic physical conditions (1 condition: 23%; 2 conditions: 27%; 3 conditions: 30%; 4 conditions: 31%; 5 or more conditions: 41%). Only 16% of those with no listed physical conditions recorded CES-D scores of 16 or above. Across the listed physical conditions the prevalence of 'probable depression' ranged from 24% for hypertension; 35% for emphysema; 35% for dermatitis to 36% for stroke. The dose-response relationship is reduced when functional limitations and self-rated health are taken into account, suggesting that these factors mediate the relationship. CONCLUSIONS A clear dose-response relationship exists between the number of chronic physical problems and depressive symptoms. The relationship between multimorbidity and depression appears to be mediated via self-perceived health related quality of life. Primary care practitioners will identify more cases of depression if they focus on those with more than one chronic health problem, no matter what the problems may be, being especially aware in the group who rate their health as poor/fair.

Abstract
OBJECTIVE General practice-based case management is effective in improving symptoms, adherence, and the perceived process of care of patients living with major depression. The aim was to explore the patients' perceptions of practice-based depression case management, their satisfaction with it and how living with depression contextualizes case management. METHODS This qualitative study was nested in a large cluster-randomized controlled trial on the effectiveness of case management for patients living with major depression. Case management was provided over 12 months by practice-based health care assistants, who monitored symptoms. We undertook semi-structured interviews with 41 patients, then transcribed and analysed them using qualitative content analysis. RESULTS Patients described depression as the unfortunate situation, where loneliness and lack of energy lead to being unable to actively seek help. Case management was appreciated because of regular, proactive contact and support by health care assistants. It was crucial to patients that they could trust the health care assistant. Some patients complained that case management was undertaken too mechanically and lacked empathy. CONCLUSION Patients living with depression may perceive practice-based case management as beneficial if carried out in a trustworthy and empathetic manner. PRACTICE IMPLICATIONS General practices should ensure that depression case management is patient-centered and non-mechanical.

Abstract
PURPOSE To examine the natural course and outcome of major depressive disorder (MDD) in primary care over 39 months. METHODS Prospective cohort study of 1,338 consecutive attendees with follow-up after 6, 12, and 39 months with DSM-IV MDD using the Composite International Diagnostic Interview (CIDI). We measured severity of depressive symptoms (Patient Health Questionnaire 9), somatic symptoms (Patient Health Questionnaire 15), and mental and physical function (Short Form 12, mental and physical component summary). Analysis of variance and random coefficient models were performed. RESULTS At baseline, 174 people (13%) had MDD of which 17% had a chronic and 40% had a fluctuating course, while 43% remitted. Patients with chronic courses had more severe depressive symptoms (mean difference 6.54; 95% CI 4.38-8.70), somatic symptoms (mean difference 3.31; 95% CI 1.61-5.02), and greater mental dysfunction (mean difference -10.49; 95% CI -14.42 to -6.57) at baseline than those who remitted from baseline, independent of age, sex, level of education, presence of a chronic disease, and a lifetime history of depression. CONCLUSIONS Although 43% of patients with MDD attending primary care recover, this leaves a majority of patients (57%) who have a chronic or intermittent course. Chronic courses are associated with higher levels of depressive symptoms and somatic symptoms and greater mental dysfunction at baseline.

Abstract
BACKGROUND There is little evidence as to whether or not guideline concordant care in general practice results in better clinical outcomes for people with anxiety and depression. This study aims to determine possible associations between guideline concordant care and clinical outcomes in general practice patients with depression and anxiety, and identify patient and treatment characteristics associated with clinical improvement. METHODS This study forms part of the Netherlands Study of Depression and Anxiety (NESDA).Adult patients, recruited in general practice (67 GPs), were interviewed to assess DSM-IV diagnoses during baseline assessment of NESDA, and also completed questionnaires measuring symptom severity, received care, socio-demographic variables and social support both at baseline and 12 months later. The definition of guideline adherence was based on an algorithm on care received. Information on guideline adherence was obtained from GP medical records. RESULTS 721 patients with a current (6-month recency) anxiety or depressive disorder participated. While patients who received guideline concordant care (N=281) suffered from more severe symptoms than patients who received non-guideline concordant care (N=440), both groups showed equal improvement in their depressive or anxiety symptoms after 12 months. Patients who (still) had moderate or severe symptoms at follow-up, were more often unemployed, had smaller personal networks and more severe depressive symptoms at baseline than patients with mild symptoms at follow-up. The particular type of treatment followed made no difference to clinical outcomes. CONCLUSION The added value of guideline concordant care could not be demonstrated in this study. Symptom severity, employment status, social support and comorbidity of anxiety and depression all play a role in poor clinical outcomes.

Abstract
BACKGROUND Depression is highly comorbid with alcohol and drug problems, resulting in greater impairment, reduced treatment adherence and poor outcomes. Little evidence exists to support the use of mental health screening tools in routine addiction treatment. This study tested the validity and reliability of PHQ-9 and PHQ-2 as depression case finding tools in an outpatient drug treatment sample in the United Kingdom. METHODS A sample of 103 patients took part in diagnostic assessments using CIS-R and completed brief screening questionnaires. A subgroup of 60 patients completed retests after 4 weeks. Diagnostic results were compared to brief measures using receiver operating characteristic (ROC) curves. Psychometric properties were also calculated to evaluate the validity and reliability of self-completed questionnaires. RESULTS A PHQ-9 score ≥ 12 had a sensitivity of 81% and specificity of 75% for major depression, also displaying good retest reliability (intra-class correlation, 0.78) and internal consistency (Cronbach's alpha, 0.84). PHQ-2 had 68% sensitivity and 70% specificity, with more modest retest reliability (0.66) and internal consistency (0.64). LIMITATIONS Diagnostic interviews did not consider the temporal sequencing of the onset of drug use and mental health problems. CONCLUSIONS PHQ-9 is a valid and reliable depression screening tool for drug and alcohol users. The brevity and ease of administration of self-completed questionnaires make them useful clinical tools in addiction services commonly encountering a high prevalence of depression.

Abstract
BACKGROUND Numerous observational studies demonstrate associations between social context and depressive symptoms, yet few intervention trials exist in this arena. AIMS This review examines intervention trials that explore the impact of contextual change on depressive symptoms. METHODS Electronic literature databases of PubMed and PsycINFO, bibliographies of retrieved articles and the publicly available internet were searched for English-language articles published between 1997 and 2008. Peer-reviewed studies were eligible for inclusion if they reported contextual interventions and depressive symptoms measures in adult populations without other significant underlying medical or psychological illness. In total, 2,128 studies met search term criteria. Of these, 13 studies meeting inclusion criteria were classified by type of intervention. Qualitative synthesis was used to interpret the mental health impact of contextual interventions. RESULTS The interventions focused on employment, housing, poverty, parenting and violence. Eight of these studies reported a decrease in depressive symptoms and/or psychological distress in intervention groups. Interventions varied in focus, length of follow-up and measures of depressive symptoms. CONCLUSIONS Contextual interventions for the prevention and treatment of depressive symptoms and psychological distress can be effective, though very limited data exist in this field. Policy implications include a greater emphasis on improving context to decrease depression and other mental disorders.

Promotoras as mental health practitioners in primary care: a multi-method study of an intervention to address contextual sources of depression. J Community Health 2011; 36:316-31.

Abstract
We assessed the role of promotoras--briefly trained community health workers--in depression care at community health centers. The intervention focused on four contextual sources of depression in underserved, low-income communities: underemployment, inadequate housing, food insecurity, and violence. A multi-method design included quantitative and ethnographic techniques to study predictors of depression and the intervention's impact. After a structured training program, primary care practitioners (PCPs) and promotoras collaboratively followed a clinical algorithm in which PCPs prescribed medications and/or arranged consultations by mental health professionals and promotoras addressed the contextual sources of depression. Based on an intake interview with 464 randomly recruited patients, 120 patients with depression were randomized to enhanced care plus the promotora contextual intervention, or to enhanced care alone. All four contextual problems emerged as strong predictors of depression (chi square, p < .05); logistic regression revealed housing and food insecurity as the most important predictors (odds ratios both 2.40, p < .05). Unexpected challenges arose in the intervention's implementation, involving infrastructure at the health centers, boundaries of the promotoras' roles, and "turf" issues with medical assistants. In the quantitative assessment, the intervention did not lead to statistically significant improvements in depression (odds ratio 4.33, confidence interval overlapping 1). Ethnographic research demonstrated a predominantly positive response to the intervention among stakeholders, including patients, promotoras, PCPs, non-professional staff workers, administrators, and community advisory board members. Due to continuing unmet mental health needs, we favor further assessment of innovative roles for community health workers.

Which version of the geriatric depression scale is most useful in medical settings and nursing homes? Diagnostic validity meta-analysis. Am J Geriatr Psychiatry 2010; 18:1066-77. [PMID: 21155144 DOI: 10.1097/jgp.0b013e3181f60f81] [Citation(s) in RCA: 69] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/21/2022]
Abstract
BACKGROUND The Geriatric Depression Scale (GDS) has been evaluated in individual studies, but its validity and added value in medical settings and nursing homes is uncertain. Therefore, the authors conducted a meta-analysis, analyzing the diagnostic accuracy of long, short, and ultrashort versions of the GDS and stratified this into those with and without cognitive impairment. METHODS A comprehensive search identified 69 studies that measured the diagnostic validity of the GDS against a semistructured psychiatric interview, and of these, 43 analyses (in 36 publications) took place inmedical settings. Twenty-one studies examined the GDS₃₀, 12 studies examined the GDS₁₅, and 3 examined the GDS₄(/)₅. For comparison, the authors also summarized studies examining unassisted clinical judgment. Heterogeneity was moderate to high; therefore, random effects meta-analysis was used. RESULTS Across all studies, the prevalence of late-life depression was 29.2% (95% confidence interval [CI] = 24.7%–33.9%), with no difference between inpatients, outpatients, and nursing homes. Diagnostic accuracy of the GDS₃₀ aftermeta-analytic weighting was given by a sensitivity of 81.9% (95% CI = 76.4%–86.9%) and a specificity of 77.7% (95% CI = 73.0%–82.1%). For the GDS₁₅, sensitivity was 84.3% (95% CI = 79.7%–88.4%) and specificity was 73.8% (95% CI = 68.0%–79.2%). For the GDS₄(/)₅, the sensitivity and specificity were 92.5% (95% CI = 85.5%–97.4%) and 77.2% (95% CI = 66.6%–86.3%), respectively. Results were not significantly influenced by the presence of dementia. Concerning added value, when identification using the GDS was compared with routine clinicians’ ability to diagnose late-life depressions, at a prevalence of 30%, of every 100 attendees, the GDS₃₀ would help correctly identify an additional 22 people as depressed but at a cost of 13 additional false positives. The GDS₁₅ performed the same as GDS₃₀ but with 15 false positives. The ultrashort form would help identify an additional 25 true positives with only 10 false positives. Thus, the best option when choosing between versions of the GDS seems to be the GDS₄(/)₅. CONCLUSION All versions of the GDS yield potential added value in medical settings, but the GDS₄(/)₅ is the most efficient. In nursing homes, given an absence of data on the GDS₄(/)₅, the GDS₁₅ may be preferred until more studies are reported.
