Mixed anxiety and depressive disorder outcomes: prospective cohort study in primary care

Predictors of common mental disorders and psychiatric medication use among faculty members

PURPOSE

Identify the predictors of common mental disorders (CMD) and psychiatric medication use by faculty members in different teaching units of a public university.

DESIGN AND METHODS

A cross-sectional study on 253 faculty.

FINDINGS

Being single, not having children, and not practicing physical activity were identified as predictors of CMD. Relative to psychiatric medication use, the predictors were the following: being homosexual, teaching classes in the biological sciences field, using medication for the urinary tract and sexual hormones, presenting mental disorder/sleep disorder diagnoses, and being positive for CMD.

PRACTICE IMPLICATIONS

The findings of this study may subsidize more effective interventions aimed toward protecting the health and preventing aggravation in these professionals, as well as measures for promoting changes in the university work context.

Adverse employment histories, work stress and self-reported depression in the French CONSTANCES study

BACKGROUND

Job instability and disadvantaged work were shown to be associated with poor mental health, but few studies analyzed these conditions in a life course perspective. In this study, adverse employment histories are retrospectively assessed and linked to self-reported depression. Furthermore, indirect effects of later stressful psychosocial work in terms of effort-reward imbalance are investigated.

METHODS

With data from the French CONSTANCES cohort study of 13 716 male and 12 767 female employees aged 45 and older, we identify adverse employment histories between age 25 and 45, focussing on job discontinuity, job instability and cumulative disadvantage. Direct effects of these conditions on self-reported depression over a period of up to 5 years are analyzed, using discrete-time logistic regression. Indirect effects of stressful work at baseline are examined.

RESULTS

Moderately elevated odds ratios of self-reported depression are observed among participants with discontinued employment histories (number of unemployment periods; years out of work for men). Effort-reward imbalance at work is consistently related to elevated risk of self-reported depression and explains parts of the association between discontinuous employment and depression.

CONCLUSIONS

Applying a life course perspective to occupational health research extends current knowledge. Specifically, adverse employment histories in terms of recurrent job discontinuity are related to the risk of self-reported depression. This association is partly explained by exposure to a stressful psychosocial work environment. These results can instruct labour market policies and the development of targeted worksite interventions that address disadvantage throughout entire employment trajectories.

Factors associated with common mental disorders and use of psychiatric drugs in cancer outpatients

BACKGROUND

Considering the high incidence of cancer in Brazil and worldwide, the high prevalence and relevance of Common Mental Disorders (CMD) in the treatment of cancer patients, and the use of psychiatric drugs without reliably proven effectiveness, studies that contemplate this topic are needed to understand and provide rationale for the treatment of CMD in these individuals.

OBJECTIVES

This study identified prevalence and factors associated with Common Mental Disorders (CMD) and psychotropic use in cancer outpatients.

METHOD

This is a cross-sectional study with descriptive correlational design. It was developed in the chemotherapy sector of a hospital specialized in cancer. The tools used were: Self Reporting Questionnaire (SRQ-20) and structured questionnaires.

FINDINGS

Among 403 respondents, CMD prevalence was 31.5% and psychotropic use was 25.8%. CMD were associated with gender, education, family income, psychotropic use and cancer surgery. Psychotropic use was associated with gender, employment status, cancer surgery, treatment period and other physical health conditions. Logistic regressions showed CMD were associated with gender and other physical health conditions; psychotropic use was associated with gender, employment status and other conditions.

A prospective cohort study of community functioning among psychiatric outpatients

The present study analyzed the community functioning among Chinese people with common mental disorders and their relationships with different factors under the framework of Model of Human Occupation. The research team followed up a stratified random sample of 238 patients in three public psychiatric specialist outpatient clinics in Hong Kong in one year. The patients completed assessments at baseline and 12-month follow-up in four areas of community functioning (i.e., self-care, independent living skills, social skills, and work skills), self-esteem, self-efficacy, physical functioning, behavioral regulation, mental states, family expressed emotion, and perceived social stigma. The data showed that after 12 months, the patients had positive changes in self-care, work skills, and behavioral regulation. Those patients who had higher levels of self-esteem at baseline and reduced their negative reactions to stigma were more likely to improve social skills, while those patients who perceived less discrimination at baseline and enhanced their self-esteem would have a higher likelihood of making improvement in work skills. The findings implied that the rehabilitation services for people with common mental disorders might target on the enhancement of self-esteem and reduction of discrimination experience to facilitate their improvement in social skills and work skills.

'You feel like your whole world is caving in': A qualitative study of primary care patients' conceptualisations of emotional distress

General practitioners are tasked with determining the nature of patients' emotional distress and providing appropriate care. For patients whose symptoms appear to fall near the 'boundaries' of psychiatric disorder, this can be difficult with important implications for treatment. There is a lack of qualitative research among patients with symptoms severe enough to warrant consultation, but where general practitioners have refrained from diagnosis. We aimed to explore how patients in this potentially large group conceptualise their symptoms and consequently investigate lay understandings of complex distinctions between emotional distress and psychiatric disorder. Interviews were conducted with 20 primary care patients whom general practitioners had identified as experiencing emotional distress, but had not diagnosed with major depressive disorder. Participants described severe emotional experiences with substantial impact on their lives. The term 'depression' was used in many different ways; however, despite severity, they often considered their emotional experience to be different to their perceived notions of 'actual' depression or mental illness. Where anxiety was mentioned, use appeared to refer to an underlying generalised state. Participants drew on complex, sometimes fluid and often theoretically coherent conceptualisations of their emotional distress, as related to, but distinct from, mental disorder. These conceptualisations differ from those frequently drawn on in research and treatment guidelines, compounding the difficulty for general practitioners. Developing models of psychological symptoms that draw on patient experience and integrate psychological/psychiatric theory may help patients understand the nature of their experience and, critically, provide the basis for a broader range of primary care interventions.

Initial and Follow-Up Evaluations of Integrated Psychological Services for Anxiety and Depression in a Safety Net Primary Care Clinic

OBJECTIVE

Despite the recognized importance of integrated behavioral health, particularly in safety net primary care, its effectiveness in real world settings has not been extensively evaluated. This article presents 2 successive studies examining the effectiveness of integrated behavioral care in a safety net setting.

METHOD

Study 1 compared the depression and anxiety scores of predominately low-income and minority patients who underwent brief interventions (N = 147) to those of patients from a demographically similar comparison clinic without integrated psychological services, matched on baseline levels of anxiety and depression and length of time between assessments (N = 139). Study 2 did not include a control group but served as a long-term follow-up assessment of anxiety and depression for a subset of 47 patients who finished treatment and could be reached by telephone within 6-18 months of their last session.

RESULTS

Study 1 found that patients from the clinic with integrated psychology services experienced greater decreases in depression and anxiety scores than patients in the control clinic. These effects did not differ as a function of age, gender, or race. Study 2 found that patients continued to decline in depression and anxiety over time, with lower scores at the last session and even lower scores after longer-term follow-up ranging from 6 to18 months. These improvements remained significant when controlling for other interim mental health treatments.

CONCLUSION

These results support the short- and long-term treatment effects of brief primary care behavioral interventions, further strengthening the case for integrated behavioral healthcare in safety net settings.

Quality of Life in Brazil's Family Health Strategy: Common Mental Disorders, Use of Psychotropic Drugs and Sociodemographic Factors

The aim of the study was to evaluate the patients' quality of life in Brazil's Family Health Strategy and its association with sociodemographic factors, presence of common mental disorders, and use of psychotropic drugs. Were interviewed 442 patients. Tools were: World Health Organization Quality of Life Assessment-Bref and Self Reporting Questionnaire. Male and low education were strongly associated with higher quality of life. Use of psychotropic drugs and the presence of CMD were strongly associated with poor quality of life. There is a pressing need for primary health care professionals to invest in tracking, and in holistic interventions that are able to cover the healthcare needs of these vulnerable groups.

Transdiagnostic Cognitive Behavioral Therapy Versus Treatment as Usual in Adult Patients With Emotional Disorders in the Primary Care Setting (PsicAP Study): Protocol for a Randomized Controlled Trial

Background

Demand for primary care (PC) services in Spain exceeds available resources. Part of this strong demand is due to the high prevalence of emotional disorders (EDs)—anxiety, depression, and somatic symptom disorders—and related comorbidities such as pain or chronic illnesses. EDs are often under- or misdiagnosed by general practitioners (GPs) and, consequently, treatment is frequently inadequate.

Objective

We aim to compare the short- and long-term effectiveness of group-delivered transdiagnostic cognitive behavioral therapy (TD-CBT) versus treatment as usual (TAU) in the treatment of EDs in the PC setting in Spain. We also aim to compare the effect of these treatments on disability, quality of life, cognitive-emotional factors, and treatment satisfaction.

Methods

Here we present the study design of a two-arm, single-blind, randomized controlled trial (N=1126) to compare TAU to TD-CBT for EDs. TAU will consist primarily of pharmacological treatment and practical advice from the GP while TD-CBT will be administered in seven 90-minute group sessions held over a period ranging from 12 to 14 weeks. Psychological assessments are carried out at baseline (ie, pretreatment); posttreatment; and at 3-, 6-, and 12-month follow-up. The study is conducted in approximately 26 PC centers from the National Health System in Spain.

Results

This study was initiated in December 2013 and will remain open to new participants until recruitment and follow-up has been completed. We expect all posttreatment evaluations to be completed by December 2017, and follow-up will end in December 2018.

Conclusions

We expect the TD-CBT group to have better results compared to TAU on all posttreatment measures and that this improvement will be maintained during follow-up. This project could serve as a model for use in other areas or services of the National Health System in Spain and even in other countries.

The relevance of 'mixed anxiety and depression' as a diagnostic category in clinical practice

According to ICD-10 criteria, mixed anxiety and depressive disorder (MADD) is characterized by co-occurring, subsyndromal symptoms of anxiety and depression, severe enough to justify a psychiatric diagnosis, but neither of which are clearly predominant. MADD appears to be very common, particularly in primary care, although prevalence estimates vary, often depending on the diagnostic criteria applied. It has been associated with similarly pronounced distress, impairment of daily living skills, and reduced health-related quality of life as fully syndromal depression and anxiety. Although about half of the patients affected remit within a year, non-remitting patients are at a high risk of transition to a fully syndromal psychiatric disorder. The validity and clinical usefulness of MADD as a diagnostic category are under debate. It has not been included in the recently released DSM-5 since the proposed diagnostic criteria turned out to be not sufficiently reliable. Moreover, reviewers have disputed the justification of MADD based on divergent results regarding its prevalence and course, diagnostic stability over time, and nosological inconsistencies between subthreshold and threshold presentations of anxiety and depressive disorders. We review the evidence in favor and against MADD and argue that it should be included into classification systems as a diagnostic category because it may enable patients to gain access to appropriate treatment early. This may help to reduce patients' distress, prevent exacerbation to a more serious psychiatric disorder, and ultimately reduce the societal costs of this very common condition.

Adherence to Psychotropic Medications and Associated Factors in Primary Health Care

The study aims were to analyze patients' adherence to psychotropic medications and its association with sociodemographic factors, therapeutic regimen, presence of common mental disorders, and illness factors. A descriptive cross-sectional study was carried out in ten Primary Health Care units in Brazil. The tools were the Measurement of Treatment Adherence Test and the Self Reporting Questionnaire. Nonadherence to psychotropic drugs was 88.9%. There was association between adherence and age and among patients positive for Common Mental Disorders (97.8%). In the multivariate analysis this association was not maintained. Findings indicate strategies are needed to improve medication adherence in the Primary Health Care services. However, no strategy will be effective if patients and their families are not involved in the process.

Common Mental Disorders in Primary Health Care Units: Associated Factors and Impact on Quality of Life

BACKGROUND

Considering the high worldwide prevalence of common mental disorders (CMDs), characterizing the association between CMD and quality of life (QoL) constitute a valuable measure to gauge patient's functional impairment due to CMD symptoms.

OBJECTIVE

To investigate factors associated with the incidence of CMD and its impact on the QoL in primary health care (PHC) patients.

DESIGN

Cross-sectional study completed in a municipality in Brazil. Standardized tools included the Self-Reporting Questionnaire-20 to detect CMDs and the WHOQOL-brief to assess QoL, in addition to a sociodemographic and treatment-related questionnaire.

RESULTS

A total of 41.4% of the patients met cutoff scores for a CMD, and the presence of a CMD was associated with female gender and marital status. Patients with CMDs had lower QoL scores than patients who were negative for a CMD.

CONCLUSIONS

CMDs are highly prevalent in PHC settings and affect patients' QoL. The high frequency of CMD in those that seek care through PHC necessitate incorporating mental health services into the range of available services.

Efficacy of Silexan in mixed anxiety-depression--A randomized, placebo-controlled trial

Mixed anxiety and depressive disorder (MADD; ICD-10 F41.2) is a condition characterized by subsyndromal symptoms of anxiety and depression, neither of which are clearly predominant. Silexan has been demonstrated to be efficacious in subsyndromal and syndromal anxiety disorders and co-morbid depressive symptoms. In this study 318 adult out-patients with MADD according to ICD-10 criteria, a total score ≥18 points on the Hamilton Anxiety Rating Scale (HAMA), and at least moderately severe anxious and depressed mood were randomized and received 1×80mg Silexan or placebo in double-blind fashion for a scheduled period of 70 days. Primary outcome measures were the HAMA and Montgomery Åsberg Depression Rating Scale (MADRS) total score changes between baseline and treatment end. The HAMA total score decreased by 10.8±9.6 points for Silexan and by 8.4±8.9 points for placebo (treatment group difference: p<0.01, one-sided; ANCOVA with factors for treatment and centre and the baseline value as covariate), and total score decreases of 9.2±9.9 and 6.1±7.6 points, respectively, were observed for the MADRS (p<0.001). Compared to placebo, the patients treated with Silexan had a better over-all clinical outcome and showed more pronounced improvements of impaired daily living skills and health related quality of life. Eructation was the only adverse event with a substantially higher incidence under Silexan. The study thus demonstrates that Silexan is efficacious and safe in the treatment of MADD.

A systematic review of the predictors of health service utilisation by adults with mental disorders in the UK

OBJECTIVES

To identify variables that predict health service utilisation (HSU) by adults with mental disorders in the UK, and to determine the evidence level for these predictors.

DESIGN

A narrative synthesis of peer-reviewed studies published after the year 2000. The search was conducted using four databases (ie, PsycINFO, CINAHL Plus with full text, MEDLINE and EMBASE) and completed on 25 March 2014.

SETTING

The majority of included studies were set in health services across primary, secondary, specialist and inpatient care. Some studies used data from household and postal surveys.

PARTICIPANTS

Included were UK-based studies that predicted HSU by adults with mental disorders. Participants had a range of mental disorders including psychotic disorders, personality disorders, depression, anxiety disorders, eating disorders and dementia.

PRIMARY OUTCOME

A wide range of HSU outcomes were examined, including general practitioner (GP) contacts, medication usage, psychiatrist contacts, psychotherapy attendances, inpatient days, accident and emergency admissions and 'total HSU'.

RESULTS

Taking into account study quality, 28 studies identified a range of variables with good preliminary evidence supporting their ability to predict HSU. Of these variables, comorbidity, personality disorder, age (heterogeneous age ranges), neurotic symptoms, female gender, a marital status of divorced, separated or widowed, non-white ethnicity, high previous HSU and activities of daily living, were associated with increased HSU. Moreover, good preliminary evidence was found for associations of accessing a primary care psychological treatment service and medication use with decreased HSU.

CONCLUSIONS

The findings can inform decisions about which variables might be used to derive mental health clusters in 'payment by results' systems in the UK. The findings also support the need to investigate whether combining broad diagnoses with care pathways is an effective method for mental health clustering, and the need for research to further examine the association between mental health clusters and HSU.

Quality of life, sense of coherence and experiences with three different treatments in patients with psychological distress in primary care: a mixed-methods study

Background

Psychological distress is associated with impaired health-related quality of life (HRQL) and poor sense of coherence (SOC). In a previous study, we found that therapeutic acupuncture (TA) and an integrative treatment that combined TA with person-centred approach in a salutogenic dialogue (IT) alleviated anxiety and depression significantly more than conventional treatment (CT) in primary care patients. Here, we report on secondary analyses regarding the HRQL and SOC from that previous pragmatic randomised controlled trial (RCT).

Method

Quantitative and qualitative design. One hundred twenty patients were referred for psychological distress. Quantitative analyses were performed at baseline and after 8 weeks of treatment using the SF-36 mental component summary (MCS), physical component summary (PCS) and the Sense of Coherence-13 (SOC) questionnaires. Qualitative manifest content analyses were based on open-ended questions—“Have you experienced any changes since the start of the treatment? Will you describe these changes?”

Results

No baseline differences were found. At 8 weeks, both the IT and TA groups had statistically better scores and greater improvement from baseline on the MCS and SOC than the CT group. The effect sizes were large. No significant differences were found between the IT and TA groups or in relation to the PCS. SOC was highly correlated with the MCS but not with the PCS. Dropout rates were low.

The experiences of the intervention resulted in four categories: Being heading back; Status quo; Feeling confirmed; and Feeling abandoned, with 13 related subcategories.

Conclusion

IT and TA seem to improve sense of coherence and mental health status in primary care patients with psychological distress, whereas CT appears to be less beneficial. IT and TA appear to be well-accepted and may serve as useful adjunct treatment modalities to standard primary care. Our results are consistent with much of the previous research in highlighting a strong relationship between SOC and mental health status. The written qualitative data described feeling confirmed and feeling increased self-efficacy, self-care and faith in the future. Those in the CT group, however, described feeling abandoned, missing treatment and experiencing increased emotional and physical problems. More research is needed.

Anxious forms of depression

Previous research has described distinctive features for anxious and nonanxious forms of major depression. The concept of "mixed anxiety depression disorder" (MADD) refers to a milder degree of the anxious form of depression, since the depressive symptoms fall short of the number required for a diagnosis of major depression. It is argued that this can be thought of as a subclinical form of anxious depression, rather than a separate disorder in its own right. In view of its substantial prevalence in general medical settings, its associated disability and its public health importance, it deserves to be recognized, and seen as being continuous with the more severe forms of anxious depression. It will therefore be included in the Field Trials of the version of the ICD-11 (where ICD is the International Classification of Disease) intended for primary care. It is argued that current anxiety, depression (without anxiety), and anxious depression would cover most of the psychologically distressed patients seen in general medical settings, using a pseudodimensional system.

Bereavement and common mental disorders in middle-aged adults: results from the Brazilian longitudinal study of adult health (ELSA-Brasil)

BACKGROUND

Although bereavement is accompanied with depression and anxiety symptoms, it is usually not associated with increased rates of mental disorders in North American and European samples. Data from low- and middle-income countries are, however, scarce. We therefore explored the prevalence of mental disorders after bereavement in Brazil.

METHODS

The Clinical Interview Schedule-Revised (CIS-R) was used for psychiatric assessment of 15,105 participants from the Brazilian Health Longitudinal Study (ELSA-Brasil). We asked whether the participant suffered loss of a first-degree relative/spouse within 6 and 12 months prior to the interview.

RESULTS

The prevalence within 6 and 12 months after bereavement for major depressive disorder (MDD, 4.3% for 6 and 12 months) and anxiety disorders (17.4% and 15.9%, respectively) did not differ compared to non-bereaved participants, except for panic disorder. Sociodemographic and clinical data were also similar. Conversely, we found increased 12-month prevalence of bereaved-related (vs. non-related) mixed anxiety and depressive disorder (15.7% vs. 12.5%, respectively) and common mental disorder (30.7% vs. 26.2%); diagnoses that are solely based on the number and severity of depression and anxiety symptoms.

LIMITATIONS

Although this was a cross-sectional study, the sample size was large.

CONCLUSIONS

Bereavement was associated with greater psychopathological burden but not with increased prevalence of MDD and anxiety disorder diagnoses, therefore highlighting the need of carefully monitoring subjects whom recently experienced bereavement. Our findings also support and provide a "cultural validator" for excluding bereavement as an exclusionary criterion for MDD diagnosis.

Defining anxious depression: a review of the literature

The diagnosis of anxious depression is presently inconsistent. The many different definitions of anxious depression have complicated its diagnosis, leading to clinical confusion and inconsistencies in the literature. This article reviewed the extant literature in order to identify the varying definitions of anxious depression, which were then compared using Feighner's diagnostic criteria. Notably, these suggest a different clinical picture of patients with anxious depression. For instance, relying on The International Classification of Diseases (ICD) or Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnoses yields a clinical picture of a comparatively mild or transient disorder; in contrast, using dimensional criteria such as DSM criteria combined with additional rating scales-most commonly the anxiety somatization factor score from the Hamilton Depression Rating Scale (HAM-D)-yields a more serious clinical picture. The evidence reviewed here suggests that defining anxious depression in a dimensional manner may be the most useful and clinically relevant way of differentiating it from other types of mood and anxiety disorders, and of highlighting the most clinically significant differences between patients with anxious depression versus depression or anxiety alone.

Recent trends in the incidence of anxiety diagnoses and symptoms in primary care

BACKGROUND

Anxiety is common, with significant morbidity, but little is known about presentations and recording of anxiety diagnoses and symptoms in primary care. This study aimed to determine trends in incidence and socio-demographic variation in General Practitioner (GP) recorded diagnoses of anxiety, mixed anxiety/depression, panic and anxiety symptoms.

METHODOLOGY/PRINCIPAL FINDINGS

Annual incidence rates of anxiety diagnoses and symptoms were calculated from 361 UK general practices contributing to The Health Improvement Network (THIN) database between 1998 and 2008, adjusted for year of diagnosis, gender, age, and deprivation. Incidence of GP recorded anxiety diagnosis fell from 7.9 to 4.9/1000PYAR from 1998 to 2008, while incidence of anxiety symptoms rose from 3.9 to 5.8/1000PYAR. Incidence of mixed anxiety/depression fell from 4.0 to 2.2/1000PYAR, and incidence of panic disorder fell from 0.9/1000PYAR in 1998 to 0.5/1000PYAR in 2008. All these entries were approximately twice as common in women and more common in deprived areas. GP-recorded anxiety diagnoses, symptoms and mixed anxiety/depression were commonest aged 45-64 years, whilst panic disorder/attacks were more common in those 16-44 years. GPs predominately use broad non-specific codes to record anxiety problems in the UK.

CONCLUSIONS/SIGNIFICANCE

GP recording of anxiety diagnoses has fallen whilst recording of anxiety symptoms has increased over time. The incidence of GP recorded diagnoses of anxiety diagnoses was lower than in screened populations in primary care. The reasons for this apparent under-recording and whether it represents under-detection in those being seen, a reluctance to report anxiety to their GP, or a reluctance amongst GPs to label people with anxiety requires investigation.
