The societal cost of depression: evidence from 10,000 Swedish patients in psychiatric care

Sedentary behaviors, physical activity, and changes in depression and psychological distress symptoms in older adults

BACKGROUND

Television (TV) viewing and computer use have been associated with higher risk of depression, but studies specifically assessing the impact of these and other types of sedentary behaviors (SBs) on the mental health of older adults are scarce and their results are inconclusive. Similarly, the association between specific types of recreational physical activity (rPA) and mental health in older adults is poorly understood.

METHODS

In 2012, information on SBs, rPA, and other health behaviors was collected with validated questionnaires from community-dwelling older adults participating in the Seniors-ENRICA cohort. In 2012 and 2015, symptoms of depression and mental distress were assessed using the GDS-10 and the General Health Questionnaire-12 (GHQ-12), respectively.

RESULTS

Time spent watching TV was prospectively associated with higher (worse) GDS-10 scores in women (β [95% confidence interval (CI)] comparing the second and third tertiles of TV viewing to the first: 0.21 [-0.04 to 0.46] and 0.37 [0.13-0.62], respectively; P-trend: < 0.01), but not in men (-0.11 [-0.35 to 0.13] and -0.18 [-0.44 to 0.08]; P-trend: 0.16). Women, but not men, who spent more time in other SBs, including reading, using the computer and commuting, showed a lower number of depressive symptoms (-0.19 [-0.44 to 0.06] and -0.34 [-0.60 to -0.08]; P-trend: 0.01) and lower (better) GHQ-12 scores (-0.33 [-0.67 to -0.00] and -0.35 [-0.69 to -0.00]; P-trend: 0.05) at follow-up. Both in men and women, higher levels of rPA, such as walking, practicing sports, and do-it-yourself activities, were associated with lower GDS-10 scores (-0.07 [-0.25 to 0.11] and -0.19 [-0.36 to -0.01]; P-trend: 0.04) and with lower GHQ-12 scores (-0.02 [-0.26 to 0.22] and -0.23 [-0.47 to -0.00]; P-trend: 0.06).

CONCLUSIONS

Older women who spent more time watching TV and less time in other SBs showed a higher number of depressive symptoms. Data suggest that increasing rPA may improve mental health in older adults, particularly among women.

Lowered quality of life in mood disorders is associated with increased neuro-oxidative stress and basal thyroid-stimulating hormone levels and use of anticonvulsant mood stabilizers

RATIONALE, AIMS

Major affective disorders including bipolar disorder (BD) and major depressive disorder (MDD) are associated with impaired health-related quality of life (HRQoL). Oxidative stress and subtle thyroid abnormalities may play a pathophysiological role in both disorders. Thus, the current study was performed to examine whether neuro-oxidative biomarkers and thyroid-stimulating hormone (TSH) levels could predict HRQoL in BD and MDD.

METHODS

This cross-sectional study enrolled 68 BD and 37 MDD patients and 66 healthy controls. The World Health Organization (WHO) QoL-BREF scale was used to assess 4 QoL subdomains. Peripheral blood malondialdehyde (MDA), advanced oxidation protein products, paraoxonaxe/CMPAase activity, a composite index of nitro-oxidative stress, and basal TSH were measured.

RESULTS

In the total WHOQoL score, 17.3% of the variance was explained by increased advanced oxidation protein products and TSH levels and lowered CMPAase activity and male gender. Physical HRQoL (14.4%) was associated with increased MDA and TSH levels and lowered CMPAase activity. Social relations HRQoL (17.4%) was predicted by higher nitro-oxidative index and TSH values, while mental and environment HRQoL were independently predicted by CMPAase activity. Finally, 73.0% of the variance in total HRQoL was explained by severity of depressive symptoms, use of anticonvulsants, lower income, early lifetime emotional neglect, MDA levels, the presence of mood disorders, and suicidal ideation.

CONCLUSIONS

These data show that lowered HRQoL in major affective disorders could at least in part result from the effects of lipid peroxidation, protein oxidation, lowered antioxidant enzyme activities, and higher levels of TSH.

Is manager support related to workplace productivity for people with depression: a secondary analysis of a cross-sectional survey from 15 countries

OBJECTIVES

To examine variations in manager reactions and support for people with depression and to investigate how these reactions are related to (1) absenteeism and (2) presenteeism due to depression among employees with self-reported depression across 15 diverse countries.

DESIGN

Secondary data analysis of cross-sectional survey data.

SETTING

15 countries, diverse in geographical region and gross domestic product (GDP): Brazil, Canada, China, Denmark, France, Germany, Great Britain, Italy, Japan, Mexico, Spain, South Africa, South Korea, Turkey and the USA.

PARTICIPANTS

16 018 employees and managers (approximately 1000 per country).

PRIMARY AND SECONDARY OUTCOME MEASURES

We assessed level of absenteeism as measured by number of days taken off work because of depression and presenteeism score.

RESULTS

On average, living in a country with a greater prevalence of managers saying that they avoided talking to the employee about depression was associated with employees with depression taking more days off work (B 4.13, 95% CI 1.68 to 6.57). On average, living in a country with a higher GDP was marginally associated with employees with depression taking more days off of work (p=0.09). On average, living in a country with a greater prevalence of managers actively offering help to employees with depression was associated with higher levels of presenteeism (B 7.08, 95% CI 6.59 to 7.58). Higher country GDP was associated with greater presenteeism among employees with depression (B 3.09, 95% CI 2.31 to 3.88).

CONCLUSIONS

Manager reactions were at least as important as country financial resources. When controlling for country GDP, working in an environment where managers felt comfortable to offer help and support to the employee rather than avoid them was independently associated with less absenteeism and more presenteeism.

The economic burden of inpatient care of depression in Poznan (Poland) and Kiel (Germany) in 2016

Depression is a global health problem associated with a significant public health burden and costs. Although studies on costs of diseases are being considered as an increasingly important factor for health policies, information concerning costs of inpatient care of depression is still insufficient. Thus, the main aim of this study was to evaluate costs of hospitalization of patients treated in 2016 in psychiatric clinics in Poznan (Poland) and in Kiel (Germany) and to analyze treatment used in these centers. The study was conducted from September 2017 to February 2018. 545 hospital records were considered (187 in Poznan and 358 in Kiel). Eventually, 490 hospital records were included, 168 in Poland and 322 in Germany. In general, the costs were calculated based on the patients’ sex and diagnosis (F32 and F33) separately and, subsequently, the outcomes were added and multiplied by the length of hospital stay, giving the cost of hospitalization. The annual cost of inpatient care of depression in 2016 was EUR 491,067.19 (x¯=EUR2923.02) in Poznan and EUR 2,847,991.00 x¯=EUR8844.69 in Kiel. In Poznan, hospitalization was underfunded reaching EUR 183,042.55 (37.27% of total costs in Poznan). In Poznan, the most frequently prescribed medicine was quetiapine, followed by olanzapine and venlafaxine, whereas in Kiel it was venlafaxine, followed by mirtazapine and promethazine. Although non-pharmacological therapies were commonly used in both centers, in Kiel this type of treatment was better structured. The study confirms the degree of the economic burden of inpatient care of depression. The underfunding of mental health revealed, emphasizes the need for urgent amendment of organization and funding of mental health care in Poland. Patients in Poznan were hospitalized on average 10 days longer than in Kiel, thus a reduction of length of hospitalization in Poznan seems possible. Although pharmacotherapy seemed to be comprehensive in both centers, there were some differences between Poznan and Kiel. Access to non-pharmacological therapies during outpatient care was limited in Poznan, however, compared to Kiel.

The Relationship between Air Pollution and Depression in China: Is Neighbourhood Social Capital Protective?

There is increasing evidence from the developed world that air pollution is significantly related to residents’ depressive symptoms; however, the existence of such a relationship in developing countries such as China is still unclear. Furthermore, although neighbourhood social capital is beneficial for health, whether it is a protective factor in the relationship between health and environment pollution remains unclear. Consequently, we examined the effects of cities’ PM_2.5 concentrations on residents’ depressive symptoms and the moderating effects of neighbourhood social capital, using data from the 2016 wave of China Labourforce Dynamics Survey and the real-time remote inquiry website of Airborne Fine Particulate Matter and Air Quality Index. Results showed that PM_2.5 concentrations and neighbourhood social capital may increase and decrease respondents’ depressive symptoms, respectively. Notably, neighbourhood social capital decreased the negative effect of PM_2.5 concentrations on respondents’ depressive symptoms. These analyses contributed to the understanding of the effect of air pollution on mental health in China and confirmed that neighbourhood social capital were protective factors in the relationship between health and environment hazards.

Neurotransmitter receptor genotypes associated with mental and behavioral disorders

AIM

Investigation of association studies within the field of mental and behavioral disorders is of value given their complex molecular etiology including epistatic interactions of multiple genes with small effects.

MATERIALS & METHODS

Utilizing biomedical text mining, associations are uncovered for all mental and behavioral conditions listed in Diagnostic and Statistical Manual of Mental Disorders Text Revision. Specifically, a computational pipeline is designed to retrieve neurotransmitter receptor variations from biomedical literature with a text mining approach, where unique polymorphisms are also mined.

RESULTS

Analyses of 1337 unique neurotransmitter receptors and 465 distinct conditions yield 1568 unique gene-disease associations.

CONCLUSION

This study takes an unconventional approach to association studies and generates a novel dataset of associations for disorders such as major depression and schizophrenia, which provides a global perspective for their genetic etiology.

Cost-effectiveness of supported employment adapted for people with affective disorders

OBJECTIVE

The individual enabling and support (IES) model was effective in gaining competitive employment for people with affective disorders compared with traditional vocational rehabilitation (TVR) services in a randomized controlled trial in a Swedish setting. The object of this study is to perform a cost-effectiveness analysis of IES comparing to TVR.

METHODS

We considered the costs of intervention and productivity gain due to increased competitive employment. We estimated quality of life using EuroQol 5 Dimension (EQ-5D) and Manchester Short Assessment of Quality of Life (MANSA) scale. EQ-5D was translated into quality-adjusted life-years (QALY), using the UK, Danish, and Swedish tariffs. We performed the analysis from a societal perspective with a one-year timeframe.

RESULTS

The cost of IES was €7247 lower per person per year (2014 prices) compared to TVR. There were no significant differences in QALY improvement within or between groups. However, quality of life measured by the MANSA scale significantly improved over the study period in IES.

LIMITATIONS

Besides the small sample size, details on the intervention costs for both IES and TVR group were unavailable and had to be obtained from external sources.

CONCLUSIONS

Implementation of IES for people with affective disorders is most likely cost-saving and is potentially even dominating TVR, although a larger trial is required to establish this.

More secure attachment to the father and the mother is associated with fewer depressive symptoms in adolescents

AIM

To investigate whether more secure attachment to the father and the mother is associated with less depressive symptoms among adolescents, and to explore possible sex differences.

METHOD

A population-based sample of adolescents completed a school-based survey assessing demographic data, attachment to father and mother, as well as depressive symptoms. Participation rate was 80% of the eligible population, and 3,988 adolescents (1,937 boys and 2,051 girls) had complete data for the analyses.

RESULTS

Paired samples t tests showed that participants rated their attachment to mothers as slightly more secure than their attachment to fathers (t = 15.94, P < 0.001; boys: t = 5.23, P < 0.001; girls: t = 16.16, P < 0.001). In linear regression analyses there was an association between the outcome, number of depressive symptoms, and more secure attachment to the mother for boys (B = -0.532; 95% confidence interval [CI] -0.656, -0.407, P < 0.001) and for girls (B = -0.623; 95% CI -0.730, -0.516, P < 0.001). Analogous results were found for more secure attachment to the father for boys (B = -0.499; 95% CI -0.608, -0.391, P < 0.001) and for girls (B = -0.494; 95% CI -0.586, -0.401, P < 0.001).

CONCLUSIONS

Understanding the relationship between attachment to both father and mother and depressive symptoms in adolescent boys and girls is essential for further development of strategies for prevention and treatment of depression.

Associations Between Supportive Leadership Behavior and the Costs of Absenteeism and Presenteeism: An Epidemiological and Economic Approach

OBJECTIVE

This study investigates associations between supportive leadership behavior (SLB) and presenteeism/absenteeism, and estimates related costs.

METHODS

Cross-sectional data from a German industrial sample (n = 17,060) assessing SLB and presenteeism/absenteeism were used. Adjusted interval regressions were performed. The study population was split into tertiles with respect to SLB, and minimum and maximum costs for each tertile were estimated on the basis of national industry averages.

RESULTS

Low SLB was associated with higher presenteeism [-0.31, 95% confidence interval (95% CI) -0.33 to -0.28)] and absenteeism (-0.36, 95% CI -0.40 to -0.32). Compared with high SLB, the costs of low SLB for absenteeism are between 534.54 and 1675.16 Euro higher per person and year. For presenteeism, this difference ranges between 63.76 and 433.7 Euro.

CONCLUSIONS

SLB has the potential to reduce absenteeism, presenteeism, and associated costs. To contribute to workforce health, productivity, and efficiency, SLB merits being fostered by corporate policy.

Impact of initial medication non-adherence to SSRIs on medical visits and sick leaves

BACKGROUND

Initial medication non-adherence (IMNA) to antidepressants, which are commonly used to treat depression in primary care (PC), is around 6-12%. Although it is well known that post-initial non-adherence to antidepressants increases the cost of depression, the impact of IMNA on cost is unknown. The aim of this study is to assess the impact of IMNA to Selective Serotonin Reuptake Inhibitors (SSRI) on medical visits and sick leave in patients with depression treated in PC in Catalonia (Spain).

METHODS

This was a four-year retrospective register-based study (2011-2014). All PC patients of working age who received a new SSRI prescription and had a diagnosis of depression were included (N = 79,642). Treatment initiation, number of visits and days on sick leave were gathered from the database. We assessed the impact of IMNA on costs with ordered logistic regressions.

RESULTS

The 3-year incidence of IMNA was 15%. Initially non-adherent patients made a lesser number of GP visits (OR = 0.82; 95% CI = 0.79-0.84) but had more days on sick leave (OR = 1.25; 95% CI = 1.20-1.31). There were no differences in the number of specialist visits (OR = 1.04; 95% CI = 0.99-1.08).

LIMITATIONS

Differences between adherent and non-adherent patients could be explained by non-observed variables. GP recognition and documentation of depression might be inaccurate. Costs of unpaid work and use of hospital services were not considered.

CONCLUSIONS

Although IMNA decreases the use of medical PC services, it increases the number of days on sick leave. This could also indicate worse health status. These consequences are currently overlooked when considering post-initial medication non-adherence.

The direct healthcare costs associated with psychological distress and major depression: A population-based cohort study in Ontario, Canada

The objective of our study was to estimate direct healthcare costs incurred by a population-based sample of people with psychological distress or depression. We used the 2002 Canadian Community Health Survey on Mental Health and Well Being and categorized individuals as having psychological distress using the Kessler-6, major depressive disorder (MDD) using DSM-IV criteria and a comparison group of participants without MDD or psychological distress. Costs in 2013 USD were estimated by linking individuals to health administrative databases and following them until March 31, 2013. Our sample consisted of 9,965 individuals, of whom 651 and 409 had psychological distress and MDD, respectively. Although the age-and-sex adjusted per-capita costs were similarly high among the psychologically distressed ($3,364, 95% CI: $2,791, $3,937) and those with MDD ($3,210, 95% CI: $2,413, $4,008) compared to the comparison group ($2,629, 95% CI: $2,312, $2,945), the population-wide excess costs for psychological distress ($441 million) were more than twice that for MDD ($210 million) as there was a greater number of people with psychological distress than depression. We found substantial healthcare costs associated with psychological distress and depression, suggesting that psychological distress and MDD have a high cost burden and there may be public health intervention opportunities to relieve distress. Further research examining how individuals with these conditions use the healthcare system may provide insight into the allocation of limited healthcare resources while maintaining high quality care.

Societal costs of fetal alcohol syndrome in Sweden

OBJECTIVE

To estimate the annual societal cost of fetal alcohol syndrome (FAS) in Sweden, focusing on the secondary disabilities thought feasible to limit via early interventions.

METHODS

Prevalence-based cost-of-illness analysis of FAS in Sweden for 2014. Direct costs (societal support, special education, psychiatric disorders and alcohol/drug abuse) and indirect costs (reduced working capacity and informal caring), were included. The calculations were based on published Swedish studies, including a register-based follow-up study of adults with FAS, reports and databases, and experts.

RESULTS

The annual total societal cost of FAS was estimated at €76,000 per child (0-17 years) and €110,000 per adult (18-74 years), corresponding to €1.6 billion per year in the Swedish population using a prevalence of FAS of 0.2 %. The annual additional cost of FAS (difference between the FAS group and a comparison group) was estimated at €1.4 billion using a prevalence of 0.2 %. The major cost driver was the cost of societal support.

CONCLUSIONS

The cost burden of FAS on the society is extensive, but likely to be underestimated. A reduction in the societal costs of FAS, both preventive and targeted interventions to children with FAS, should be prioritized. That is, the cost of early interventions such as placement in family homes or other forms of housing, and special education, represent unavoidable costs. However, these types of interventions are highly relevant to improve the individual's quality of life and future prospects, and also, within a long-term perspective, to limit the societal costs and personal suffering.

The Association Between Air Pollution and Onset of Depression Among Middle-Aged and Older Women

Despite recently reported associations between air pollution and acute psychiatric outcomes, the association with depression onset has not, to our knowledge, been previously examined. We conducted a prospective cohort study among 41,844 women in the Nurses' Health Study, in the United States. The women had an average age of 66.6 (standard deviation, 7.6) years, were depression-free in 1996, and were followed through 2008. May-September ozone exposures were predicted by interpolating concentrations from the 5 nearest monitors. One-, 2-, and 5-year average concentrations of particulate matter with an aerodynamic diameter less than or equal to 2.5 μm (PM2.5) were predicted at each participant's residence using a spatiotemporal model. We defined depression as report of doctor's diagnosis or use of antidepressant medication. We estimated adjusted hazard ratios with time-varying Cox models. Hazard ratios for both pollutants were elevated (per 10-parts-per-billion increase in ozone, hazard ratio (HR) = 1.06; 95% confidence interval (CI): 1.00, 1.12; per 10-μg/m3 increase in 1-year PM2.5, HR = 1.08; 95% CI: 0.97, 1.20). Associations were stronger when only antidepressant use was used to define cases (for ozone, HR = 1.08; 95% CI: 1.02, 1.14; for PM2.5, HR = 1.12; 95% CI: 1.00, 1.25). To our knowledge, these results represent the first identification of a possible association between both long-term ozone and PM2.5 exposure and depression onset. Although the stronger association specifically with antidepressant use may reflect that this endpoint better captures the onset time and milder cases, our findings should be interpreted with caution.

Early Improvement in Work Productivity Predicts Future Clinical Course in Depressed Outpatients: Findings From the CO-MED Trial

OBJECTIVE

Depression symptom severity, the most commonly studied outcome in antidepressant treatment trials, accounts for only a small portion of burden related to major depression. While lost work productivity is the biggest contributor to depression's economic burden, few studies have systematically evaluated the independent effect of treatment on work productivity and the relationship between changes in work productivity and longer-term clinical course.

METHOD

Work productivity was measured repeatedly by the Work Productivity and Activity Impairment self-report questionnaire in 331 employed participants with major depression enrolled in the Combining Medications to Enhance Depression Outcomes trial. Trajectories of change in work productivity during the first 6 weeks of treatment were identified and used to predict remission at 3 and 7 months.

RESULTS

Participants reported reduced absence from work and increased work productivity with antidepressant treatment even after controlling for changes in depression severity. Three distinct trajectories of changes in work productivity were identified: 1) robust early improvement (24%), 2) minimal change (49%), and 3) high-impairment slight reduction (27%). Compared with other participants, those with robust improvement had 3-5 times higher remission rates at 3 months and 2-5 times higher remission rates at 7 months, even after controlling for select baseline variables and remission status at week 6.

CONCLUSIONS

In this secondary analysis, self-reported work productivity improved in depressed patients with antidepressant treatment even after accounting for depressive symptom reduction. Early improvement in work productivity is associated with much higher remission rates after 3 and 7 months of treatment.

High occupational level is associated with poor response to treatment of depression

Depression may be complicated by work-related stress and, in turn, depression is a leading cause of disability in workplaces. Though available effective treatments, only one third of patients reach full remission after a first treatment trial and nearly half of the patients are non-responders. Occupational level has been found to be a reliable predictor of health outcome in the general population. In the present study we tested the potential association of occupational level of those in work with response to treatment of depression in a large multinational sample. Major depressive disorder patients (n=654) stratified in three occupational levels (high, middle, low) were considered for the present study. Response to last treatment for current episode and treatment resistant depression, defined as non-response to 2 or more previous adequate treatment trials, were considered the outcome variables. Depressed patients from the high occupational level had a higher level of educational achievement. They showed a significantly poorer response to the last treatment with lower remission rates and more treatment resistance than the other occupational level groups. They were treated less with Serotonin Reuptake Inhibitors (SRIs). Potential confounding factors did not influence the main effect. The present findings indicate that those working at a high occupational level may be a risk factor for poor response to medication for depression and this has potential implications for clinicians and their patients, for future research, for employers and for public policy.

European Union investment and countries' involvement in mental health research between 2007 and 2013

OBJECTIVES

This study aimed to estimate the commitment to mental health research by the European Union (EU) through the 7th framework (FP7) and the competitiveness and innovation (CIP) programmes during the 2007-2013 period.

METHODS

Research projects dedicated or partially related to mental health were identified using keywords in the CORDIS database that inventories all FP7 and CIP research projects. We then contacted projects' principal investigators to access the budget breakdown by country and performed an imputation of the distribution of funding between countries based on projects' and participants' characteristics where information was missing.

RESULTS

Among the 25 783 research projects funded by the FP7 and the CIP, 215 (0.8%) were specifically dedicated to mental health and 170 (0.7%) were partially related to mental health. They received €607.1 million representing 1.4% of FP7 total funding. Within the FP7-Health subprogramme, the projects represented 5.2% of funding. Important variations appeared across EU countries both for raw funding, which varied between €0 and €77M, and for funding per 100 inhabitants, which varied between €0 and €293.

CONCLUSION

EU funding of mental health research does not match the burden incurred by mental disorders and must be increased in the next framework programme.

MoodHacker Mobile Web App With Email for Adults to Self-Manage Mild-to-Moderate Depression: Randomized Controlled Trial

BACKGROUND

Worldwide, depression is rated as the fourth leading cause of disease burden and is projected to be the second leading cause of disability by 2020. Annual depression-related costs in the United States are estimated at US $210.5 billion, with employers bearing over 50% of these costs in productivity loss, absenteeism, and disability. Because most adults with depression never receive treatment, there is a need to develop effective interventions that can be more widely disseminated through new channels, such as employee assistance programs (EAPs), and directly to individuals who will not seek face-to-face care.

OBJECTIVE

This study evaluated a self-guided intervention, using the MoodHacker mobile Web app to activate the use of cognitive behavioral therapy (CBT) skills in working adults with mild-to-moderate depression. It was hypothesized that MoodHacker users would experience reduced depression symptoms and negative cognitions, and increased behavioral activation, knowledge of depression, and functioning in the workplace.

METHODS

A parallel two-group randomized controlled trial was conducted with 300 employed adults exhibiting mild-to-moderate depression. Participants were recruited from August 2012 through April 2013 in partnership with an EAP and with outreach through a variety of additional non-EAP organizations. Participants were blocked on race/ethnicity and then randomly assigned within each block to receive, without clinical support, either the MoodHacker intervention (n=150) or alternative care consisting of links to vetted websites on depression (n=150). Participants in both groups completed online self-assessment surveys at baseline, 6 weeks after baseline, and 10 weeks after baseline. Surveys assessed (1) depression symptoms, (2) behavioral activation, (3) negative thoughts, (4) worksite outcomes, (5) depression knowledge, and (6) user satisfaction and usability. After randomization, all interactions with subjects were automated with the exception of safety-related follow-up calls to subjects reporting current suicidal ideation and/or severe depression symptoms.

RESULTS

At 6-week follow-up, significant effects were found on depression, behavioral activation, negative thoughts, knowledge, work productivity, work absence, and workplace distress. MoodHacker yielded significant effects on depression symptoms, work productivity, work absence, and workplace distress for those who reported access to an EAP, but no significant effects on these outcome measures for those without EAP access. Participants in the treatment arm used the MoodHacker app an average of 16.0 times (SD 13.3), totaling an average of 1.3 hours (SD 1.3) of use between pretest and 6-week follow-up. Significant effects on work absence in those with EAP access persisted at 10-week follow-up.

CONCLUSIONS

This randomized effectiveness trial found that the MoodHacker app produced significant effects on depression symptoms (partial eta(2) = .021) among employed adults at 6-week follow-up when compared to subjects with access to relevant depression Internet sites. The app had stronger effects for individuals with access to an EAP (partial eta(2) = .093). For all users, the MoodHacker program also yielded greater improvement on work absence, as well as the mediating factors of behavioral activation, negative thoughts, and knowledge of depression self-care. Significant effects were maintained at 10-week follow-up for work absence. General attenuation of effects at 10-week follow-up underscores the importance of extending program contacts to maintain user engagement. This study suggests that light-touch, CBT-based mobile interventions like MoodHacker may be appropriate for implementation within EAPs and similar environments. In addition, it seems likely that supporting MoodHacker users with guidance from counselors may improve effectiveness for those who seek in-person support.

Cognitive remission: a novel objective for the treatment of major depression?

BACKGROUND

Cognitive dysfunction in major depressive disorder (MDD) encompasses several domains, including but not limited to executive function, verbal memory, and attention. Furthermore, cognitive dysfunction is a frequent residual manifestation in depression and may persist during the remitted phase. Cognitive deficits may also impede functional recovery, including workforce performance, in patients with MDD. The overarching aims of this opinion article are to critically evaluate the effects of available antidepressants as well as novel therapeutic targets on neurocognitive dysfunction in MDD.

DISCUSSION

Conventional antidepressant drugs mitigate cognitive dysfunction in some people with MDD. However, a significant proportion of MDD patients continue to experience significant cognitive impairment. Two multicenter randomized controlled trials (RCTs) reported that vortioxetine, a multimodal antidepressant, has significant precognitive effects in MDD unrelated to mood improvement. Lisdexamfetamine dimesylate was shown to alleviate executive dysfunction in an RCT of adults after full or partial remission of MDD. Preliminary evidence also indicates that erythropoietin may alleviate cognitive dysfunction in MDD. Several other novel agents may be repurposed as cognitive enhancers for MDD treatment, including minocycline, insulin, antidiabetic agents, angiotensin-converting enzyme inhibitors, S-adenosyl methionine, acetyl-L-carnitine, alpha lipoic acid, omega-3 fatty acids, melatonin, modafinil, galantamine, scopolamine, N-acetylcysteine, curcumin, statins, and coenzyme Q10. The management of cognitive dysfunction remains an unmet need in the treatment of MDD. However, it is hoped that the development of novel therapeutic targets will contribute to 'cognitive remission', which may aid functional recovery in MDD.

Web-Based Acceptance and Commitment Therapy for Depressive Symptoms With Minimal Support

Low-intensity interventions for people suffering from depressive symptoms are highly desirable. The aim of the present study was to investigate the outcomes of a web-based acceptance and commitment therapy (ACT)–based intervention without face-to-face contact for people suffering from depressive symptoms. Participants ( N = 39) with depressive symptoms were randomly assigned to an Internet-delivered acceptance and commitment therapy (iACT) intervention or a waiting list control condition (WLC). Participants were evaluated with standardized self-reporting measures (Beck Depression Inventory [BDI-II], Symptom Checklist–90 [SCL-90], Acceptance and Action Questionnaire [AAQ-2], Five Facet Mindfulness Questionnaire [FFMQ], Automatic Thoughts Questionnaire [ATQ], and White Bear Suppression Inventory [WBSI]) at pre- and post-measurement. Long-term effects in the iACT group were examined using a 12-month follow-up. The iACT program comprised home assignments, online feedback given by master’s-level students of psychology over a 7-week intervention period, and automated email-based reminders. Significant effects were observed in favor of the iACT group on depression symptomatology (between effect sizes [ESs] at post-treatment, iACT/WLC, g = .83), psychological and physiological symptoms (g = .60), psychological flexibility (g = .67), mindfulness skills (g = .53), and frequency of automatic thoughts (g = .57) as well as thought suppression (g = .53). The treatment effects in the iACT group were maintained over the 12-month follow-up period (within-iACT ES: BDI-II, g = 1.33; SCL-90, g = 1.04; ATQF/B [Frequency/Believability], FFMQ, WBSI, AAQ-II, g = .74-1.08). The iACT participants stated that they would be happy to recommend the same intervention to others with depressive symptoms. We conclude that an ACT-based guided Internet-delivered treatment with minimal contact can be effective for people with depressive symptoms.

Depression and violence: a Swedish population study

BACKGROUND

Depression increases the risk of a range of adverse outcomes including suicide, premature mortality, and self-harm, but associations with violent crime remain uncertain. We aimed to determine the risks of violent crime in patients with depression and to investigate the association between depressive symptoms and violent crime in a cohort of twins.

METHODS

We conducted two studies. The first was a total population study in Sweden of patients with outpatient diagnoses of depressive disorders (n=47,158) between 2001 and 2009 and no lifetime inpatient episodes. Patients were age and sex matched to general population controls (n=898,454) and risk of violent crime was calculated. Additionally, we compared the odds of violent crime in unaffected half-siblings (n=15,534) and full siblings (n=33,516) of patients with the general population controls. In sensitivity analyses, we examined the contribution of substance abuse, sociodemographic factors, and previous criminality. In the second study, we studied a general population sample of twins (n=23,020) with continuous measures of depressive symptoms for risk of violent crime.

FINDINGS

During a mean follow-up period of 3·2 years, 641 (3·7%) of the depressed men and 152 (0·5%) of the depressed women violently offended after diagnosis. After adjustment for sociodemographic confounders, the odds ratio of violent crime was 3·0 (95% CI 2·8–3·3) compared with the general population controls. The odds of violent crime in half-siblings (adjusted odds ratio 1·2 [95% CI 1·1–1·4]) and full siblings (1·5, 95% CI 1·3–1·6) were significantly increased, showing some familial confounding of the association between depression and violence. However, the odds increase remained significant in individuals with depression after adjustment for familial confounding, and in those without substance abuse comorbidity or a previous violent conviction (all p<0·0001). In the twin study, during the mean follow-up time of 5·4 years, 88 violent crimes were recorded. Depressive symptoms were associated with increased risk of violent crime and a sensitivity analysis identified little difference in risk estimate when all crimes (violent and non-violent) was the outcome.

INTERPRETATION

Risk of violent crime was increased in individuals with depression after adjustment for familial, sociodemographic and individual factors in two longitudinal studies. Clinical guidelines should consider recommending violence risk assessment in certain subgroups with depression.

Importance of social and cultural factors for attitudes, disclosure and time off work for depression: findings from a seven country European study on depression in the workplace

OBJECTIVES

Depression is experienced by a large proportion of the workforce and associated with high costs to employers and employees. There is little research on how the social costs of depression vary by social and cultural context. This study investigates individual, workplace and societal factors associated with greater perceived discomfort regarding depression in the workplace, greater likelihood of employees taking time off of work as a result of depression and greater likelihood of disclosure of depression to one's employer.

METHODS

Employees and managers (n = 7,065) were recruited from seven European countries to participate in the IDEA survey. Multivariable logistic regression models were used to examine associations between individual characteristics and country contextual characteristics in relation to workplace perceptions, likelihood of taking time off work and disclosing depression to an employer.

RESULTS

Our findings suggest that structural factors such as benefit systems and flexible working hours are important for understanding workplace perceptions and consequences for employees with depression. However, manager responses that focus on offering help to the employee with depression appear to have stronger associations with positive perceptions in the workplace, and also with openness and disclosure by employees with depression.

CONCLUSION

This study highlights the importance of individual, workplace and societal factors that may be associated with how people with depression are perceived and treated in the workplace, and, hence, factors that may be associated with openness and disclosure among employees with depression. Some responses, such as flexible working hours, may be helpful but are not necessarily sufficient, and our findings also emphasise the importance of support and openness of managers in addition to flexible working hours.

Tablet-based screening of depressive symptoms in quito, ecuador: efficiency in primary care

Depression is a frequent yet overlooked occurrence in primary health care clinics worldwide. Depression and related health screening instruments are available but are rarely used consistently. The availability of technologically based instruments in the assessments offers novel approaches for gathering, storing, and assessing data that includes self-reported symptom severity from the patients themselves as well as clinician recorded information. In a suburban primary health care clinic in Quito, Ecuador, we tested the feasibility and utility of computer tablet-based assessments to evaluate clinic attendees for depression symptoms with the goal of developing effective screening and monitoring tools in the primary care clinics. We assessed individuals using the 9-item Patient Health Questionnaire, the Quick Inventory of Depressive Symptoms-Self-Report, the 12-item General Health Questionnaire, the Clinical Global Impression Severity, and a DSM-IV checklist of symptoms. We found that 20% of individuals had a PHQ9 of 8 or greater. There was good correlation between the symptom severity assessments. We conclude that the tablet-based PHQ9 is an excellent and efficient method of screening for depression in attendees at primary health care clinics and that one in five people should be assessed further for depressive illness and possible intervention.

Resource utilisation and costs of depressive patients in Germany: results from the primary care monitoring for depressive patients trial

Background. Depression is the most common type of mental disorder in Germany. It is associated with a high level of suffering for individuals and imposes a significant burden on society. The aim of this study was to estimate the depression related costs in Germany taking a societal perspective. Materials and Methods. Data were collected from the primary care monitoring for depressive patients trial (PRoMPT) of patients with major depressive disorder who were treated in a primary care setting. Resource utilisation and days of sick leave were observed and analysed over a 1-year period. Results. Average depression related costs of €3813 were calculated. Significant differences in total costs due to sex were demonstrated. Male patients had considerable higher total costs than female patients, whereas single cost categories did not differ significantly. Further, differences in costs according to severity of disease and age were observed. The economic burden to society was estimated at €15.6 billion per year. Conclusion. The study results show that depression poses a significant economic burden to society. There is a high potential for prevention, treatment, and patient management innovations to identify and treat patients at an early stage.

The societal cost of bipolar disorder in Sweden

PURPOSE

There is a lack of comprehensive cost-of-illness studies in bipolar disorder, in particular studies based on patient-level data. The purpose of this study was to estimate the societal cost of bipolar disorder and to relate costs to disease severity, depressive episodes, hospitalisation and patient functioning.

METHODS

Retrospective resource use data in inpatient and outpatient care during 2006-2008, as well as ICD-10 diagnoses and Global Assessment of Functioning (GAF) scores, were obtained from the Northern Stockholm psychiatric clinic with a catchment area including 47% of the adult inhabitants in Stockholm. This dataset was combined with national register data on prescription pharmaceuticals and sick leave to estimate the societal cost of bipolar disorder. The study was conducted from a societal perspective, with indirect costs valued according to the human capital method.

RESULTS

The average annual cost per patient was <euro>28,011 in 2008 (n = 1,846). Indirect costs due to sick leave and early retirement represented 75%, inpatient costs 13%, outpatient costs 8%, pharmaceuticals 2% and community care another 2% of the total cost. Total costs were considerably higher during mood episodes (six times higher than in remission), for hospitalised patients (<euro>55,500 vs. <euro>22,200) and for patients with low GAF scores.

CONCLUSIONS

The high cost of bipolar disorder is driven primarily by indirect costs. Costs were strongly associated with mood episodes, hospitalisations and low GAF scores. This suggests that treatment that reduces the risk for relapses and hospitalizations and improve functioning may decrease both the societal cost of bipolar disorder and patient suffering.
