DETECTION OF ANXIETY DISORDERS IN PRIMARY CARE: A META-ANALYSIS OF ASSISTED AND UNASSISTED DIAGNOSES

A Systematic Review of the Psychometric Properties of the Patient Health Questionnaire-4 in Clinical and Nonclinical Populations

BACKGROUND

The Patient Health Questionnaire-4 (PHQ-4) is an ultra-brief instrument that measures depressive and anxiety symptoms. Although it has been frequently used in the last 15 years, no research has systematically reviewed its psychometric properties.

OBJECTIVE

This systematic review summarized, for the first time, the available published evidence on the psychometric properties of the PHQ-4.

METHODS

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and was registered in the Prospective Register of Systematic Reviews, under the identification code CRD42022381809. The search strategy was applied in Medline, PsycINFO, Web of Science, and SCOPUS from 2009 (year of publication) to 2023 (present). Two independent reviewers performed screening, data extraction, and methodological quality assessment of the studies. The data was reported through a narrative synthesis.

RESULTS

In total, 26 studies involving 93,466 participants from 19 countries, with clinical and nonclinical samples, were included. The two-factor structure was the most frequent, being invariant according to gender, age, geographic location, income, educational level, and language. The internal consistency was adequate for distress (α from 0.72 to 0.88), as well as for depression (α from 0.65 to 0.81) and anxiety (α from 0.74 to 0.84). The temporal stability of the instrument was verified through test-retest reliability, reporting an acceptable connection between both measures. Correlations with related measures were significant and in the expected direction.

CONCLUSIONS

The PHQ-4 is a reliable and valid instrument for screening depressive and anxiety symptoms, both for the clinical and nonclinical populations. Due to the brevity of its administration, the PHQ-4 could be a clinical tool that contributes to optimizing health resources.

Enhancing Provider Mental Health Screening in Primary Care: A Quality Improvement Project

Background: Depression and anxiety occur in 7.8% and 19.1% of the US population, respectively. About half of those patients are diagnosed in primary care. Objective: The purpose of this quality improvement project was to improve the screening and diagnosing of anxiety and/or depression among adult patients at a primary care clinic by implementing an evidence-based mental health screening interview technique. Methods: The team implemented a mental health screening interview technique that incorporates background, affect, trouble, handling, and empathy and motivational interviewing techniques in addition to self-report surveys. Pre- and post-intervention surveys were conducted to assess providers' perceptions of the new interview technique. ICD-10 code data were gathered to assess the effectiveness of the new mental health screening interview technique. Results: The number of documented diagnoses of single-episode major depressive disorder decreased by 18%, recurrent major depressive disorder increased by 34%, and anxiety disorders increased by 3%. There were more favorable provider perceptions of the new screening interview technique versus the traditional screening method. Conclusions: The results show an improvement in provider comfort and providers preferred the new mental health screening when using an evidence-based mental health screening interview technique. Implications for nursing: The results show the potential benefits of using a structured mental health interview with self-report screening tools when diagnosing anxiety and depression in primary care.

Practical pathway for the management of depression in the workplace: a Canadian perspective

Major depressive disorder (MDD) and other mental health issues pose a substantial burden on the workforce. Approximately half a million Canadians will not be at work in any week because of a mental health disorder, and more than twice that number will work at a reduced level of productivity (presenteeism). Although it is important to determine whether work plays a role in a mental health condition, at initial presentation, patients should be diagnosed and treated per appropriate clinical guidelines. However, it is also important for patient care to determine the various causes or triggers including work-related factors. Clearly identifying the stressors associated with the mental health disorder can help clinicians to assess functional limitations, develop an appropriate care plan, and interact more effectively with worker's compensation and disability programs, as well as employers. There is currently no widely accepted tool to definitively identify MDD as work-related, but the presence of certain patient and work characteristics may help. This paper seeks to review the evidence specific to depression in the workplace, and provide practical tips to help clinicians to identify and treat work-related MDD, as well as navigate disability issues.

Concurrent validity of the anxiety symptom-scale compared to two well-being scales: results from the Lolland-Falster health study

OBJECTIVE

To examine the concurrent validity of the Anxiety Symptom-scale against two well-being scales, the Cantril Ladder (CL) and World Health Organization Well-Being Index (WHO-5), to test the algorithm defining anxiety against these scales, and identify cut-off points for the Anxiety Symptom-scale sum score.

SUBJECTS

14,405 adult respondents completing all psychometric questions in the Lolland Falster Health Study.

METHOD

Receiver operating characteristic analyses comparing Anxiety Symptom-scale WHO-5 and CL.

RESULTS

2.5% of respondents had an anxiety disorder (3% female and 2% male) according to the Anxiety Symptom-scale algorithm. The area under the curve (AUC) was 0.87 for CL and 0.90 for WHO-5 (using inverse scores), indicating high concordance with anxiety disorder as identified by the scale. A score solely ≥2 on item 10 is a relevant cut off to low wellbeing. Anxiety disorder covers a broad range on the scale's sum score, with 3 to 4 indicating low well-being in this population sample and a sensitivity of 0.85 - 0.99 against CL and WHO-5.

CONCLUSION

The Anxiety Symptom-scale is a sensitive and valid instrument for the identification of patients in low well-being with symptoms of anxiety. A score ≥2 on the functional impact (Item 10) of all symptoms is a relevant indicator of anxiety associated with low well-being in this sample. A higher Anxiety Symptom-scale sum score is coherent with lower well-being, though without specific cut-off points. Further validation of the Anxiety Symptom-scale in a clinical setting is recommended.

Facilitators and barriers of routine psychosocial distress assessment within a stepped and collaborative care model in a Swiss hospital setting

BACKGROUND

Stepped and Collaborative Care Models (SCCMs) have shown potential for improving mental health care. Most SCCMs have been used in primary care settings. At the core of such models are initial psychosocial distress assessments commonly in form of patient screening. We aimed to assess the feasibility of such assessments in a general hospital setting in Switzerland.

METHODS

We conducted and analyzed eighteen semi-structured interviews with nurses and physicians involved in a recent introduction of a SCCM model in a hospital setting, as part of the SomPsyNet project in Basel-Stadt. Following an implementation research approach, we used the Tailored Implementation for Chronic Diseases (TICD) framework for analysis. The TICD distinguishes seven domains: guideline factors, individual healthcare professional factors, patient factors, professional interactions, incentives and resources, capacity for organizational change, and social, political, and legal factors. Domains were split into themes and subthemes, which were used for line-by-line coding.

RESULTS

Nurses and physicians reported factors belonging to all seven TICD domains. An appropriate integration of the psychosocial distress assessment into preexisting hospital processes and information technology systems was the most important facilitator. Subjectivity of the assessment, lack of awareness about the assessment, and time constraints, particularly among physicians, were factors undermining and limiting the implementation of the psychosocial distress assessment.

CONCLUSIONS

Awareness raising through regular training of new employees, feedback on performance and patient benefits, and working with champions and opinion leaders can likely support a successful implementation of routine psychosocial distress assessments. Additionally, aligning psychosocial distress assessments with workflows is essential to assure the sustainability of the procedure in a working context with commonly limited time.

Development of a keyword library for capturing PRO-CTCAE-focused "symptom talk" in oncology conversations

Objectives

As computational methods for detecting symptoms can help us better attend to patient suffering, the objectives of this study were to develop and evaluate the performance of a natural language processing keyword library for detecting symptom talk, and to describe symptom communication within our dataset to generate insights for future model building.

Materials and Methods

This was a secondary analysis of 121 transcribed outpatient oncology conversations from the Communication in Oncologist-Patient Encounters trial. Through an iterative process of identifying symptom expressions via inductive and deductive techniques, we generated a library of keywords relevant to the Patient-Reported Outcome version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) framework from 90 conversations, and tested the library on 31 additional transcripts. To contextualize symptom expressions and the nature of misclassifications, we qualitatively analyzed 450 mislabeled and properly labeled symptom-positive turns.

Results

The final library, comprising 1320 terms, identified symptom talk among conversation turns with an F1 of 0.82 against a PRO-CTCAE-focused gold standard, and an F1 of 0.61 against a broad gold standard. Qualitative observations suggest that physical symptoms are more easily detected than psychological symptoms (eg, anxiety), and ambiguity persists throughout symptom communication.

Discussion

This rudimentary keyword library captures most PRO-CTCAE-focused symptom talk, but the ambiguity of symptom speech limits the utility of rule-based methods alone, and limits to generalizability must be considered.

Conclusion

Our findings highlight opportunities for more advanced computational models to detect symptom expressions from transcribed clinical conversations. Future improvements in speech-to-text could enable real-time detection at scale.

Mental health in a heterogeneous clinical sample. A cross-sectional study of predictors and gender differences

Introduction

Women have been shown to be a vulnerable group in relation to mental health problems over time. Despite this, gender-focused studies are uncommon. The aim of this research is to study mental health in a sample of people with mental health problems and to analyze the differences and predictors focusing on gender.

Methods

A cross-sectional study is conducted in a heterogeneous clinical sample in terms of mental health problems (N = 160). Interviews with hetero-reported standardized questionnaires to collect the data are conducted. Descriptive analyses, mean difference and a regression analysis on mental health are carried out taking into account different sociodemographic, clinical and psychosocial variables.

Results

Women in the study present worse levels of mental health and subjective severity of the disorder. The main predictors of mental health are being female, followed by severity, shorter time with the diagnosis and internalized stigma.

Conclusion

Being female is the most robust predictor of worse mental health and symptomatology. Recommendations according to the results found proposing a gender perspective are suggested.

Cost-effectiveness and cost-utility evaluation of individual vs. group transdiagnostic psychological treatment for emotional disorders in primary care (PsicAP-Costs): a multicentre randomized controlled trial protocol

BACKGROUND

Emotional disorders are common, and they have become more prevalent since the COVID-19 pandemic. Due to a high attendance burden at the specialized level, most emotional disorders in Spain are treated in primary care, where they are usually misdiagnosed and treated using psychotropic drugs. This contributes to perpetuate their illness and increase health care costs. Following the IAPT programme and the transdiagnostic approach, the PsicAP project developed a brief group transdiagnostic cognitive-behavioural therapy (tCBT) as a cost-effective alternative. However, it is not suitable for everyone; in some cases, one-on-one sessions may be more effective. The objective of the present study is to compare, in cost-benefit terms, group and individual tCBT with the treatment usually administered in Spanish primary care (TAU).

METHODS

A randomized, controlled, multicentre, and single-blinded trial will be performed. Adults with mild to moderate emotional disorders will be recruited and placed in one of three arms: group tCBT, individual tCBT, or TAU. Medical data and outcomes regarding emotional symptoms, disability, quality of life, and emotion regulation biases will be collected at baseline, immediately after treatment, and 6 and 12 months later. The data will be used to calculate incremental cost-effectiveness and cost-utility ratios.

DISCUSSION

This trial aims to contribute to clinical practice research. The involvement of psychologists in primary care and the implementation of a stepped-care model for mental disorders are recommended. Group therapy and a transdiagnostic approach may help optimize health system resources and unblock waiting lists so that people can spend less time experiencing mental health problems.

Perspectives on Mental Health Screening in the Audiology Setting: A Focus Group Study Involving Clinical and Nonclinical Staff

PURPOSE

Audiology clinical guidelines recommend the use of mental health screening tools; however, they remain underutilized in clinical practice. As such, psychological concerns are frequently undetected in adults with hearing loss. This study aimed to better understand audiology clinic staff's perspectives (including audiologists, audiometrists, reception staff, and clinic managers) on how to improve detection of poor mental health by (a) exploring the role of audiology clinic staff in detecting psychological concerns in adults with hearing loss and (b) investigating the appropriateness, acceptability, and usability of several screening tools in an audiology setting.

METHOD

Eleven audiology clinic staff (M _age = 33.9 ± 7.3, range: 25-51 years) participated in a semistructured focus group. First, participants discussed the role of audiology clinic staff in detecting psychological difficulties in adults with hearing loss, including current practices and needs for improving practices. Second, participants discussed the appropriateness, acceptability, and usability of nine standardized mental health screening tools commonly used in wider health care settings.

RESULTS

Audiology clinic staff described their role in being aware of, and detecting, psychological difficulties, as well as their part in promoting an understanding of the link between hearing loss and mental health. Participants described the need to provide support following detection, and highlighted barriers to fulfilling these roles. The use of mental health screening tools was considered to be client and context specific. The language used within the screener was identified as an important factor for its acceptability by audiology clinic staff.

CONCLUSIONS

Audiology clinic staff acknowledged that they have an important role to play in the detection of psychological difficulties and identified the core barriers to using screening tools. Future research may explore the possibility of developing a mental health screening tool specific to the unique experiences of adults with comorbid hearing loss and mental health concerns.

Plasma Total Tau and Neurobehavioral Symptoms of Cognitive Decline in Cognitively Normal Older Adults

Depression and related neurobehavioral symptoms are common features of Alzheimer’s disease and other dementias. The presence of these potentially modifiable neurobehavioral symptoms in cognitively intact older adults may represent an early indication of pathophysiological processes in the brain. Tau pathology is a key feature of a number of dementias. A number of studies have found an association between tau and neurobehavioral symptoms. The current study investigated the relationship of a blood-based biomarker of tau and symptoms of depression, anxiety, worry, and sleep disturbances in 538 community based, cognitively normal older adults. Logistic regression revealed no significant relationship between plasma total tau and any measures of neurobehavioral symptoms. To assess the impact of level of tau on these relationships, participants were divided into those in the highest quintile of tau and those in the lower four quintiles. Regression analyses showed a significant relationship between level of plasma total tau and measures of depression, apathy, anxiety, worry and sleep. The presence of higher levels of plasma tau and elevated neurobehavioral symptoms may be an early indicator of cognitive decline and prodromal Alzheimer’s disease. Longitudinal research is needed to evaluate the impact of these factors on the development of dementia and may suggest areas for early intervention.

Recognizing obsessive-compulsive disorder: how suitable is the German Zohar-Fineberg obsessive-compulsive screen?

BACKGROUND

Despite the prevalence of obsessive-compulsive disorder (OCD), its precise identification remains challenging. With the Zohar-Fineberg Obsessive-Compulsive Screen (ZF-OCS; 5 or 6 items), a brief instrument is widely available mainly in English. As there is a lack of empirical studies on the ZF-OCS, the aim of the present study was to translate the items into German and investigate the instrument in a nonclinical sample.

METHODS

In two consecutive online surveys, n = 304 and n = 51 students participated. Besides the ZF-OCS, they answered established measures on OCD, depression, health anxiety, general anxiety and health-related well-being.

RESULTS

Whereas internal consistency was low (α = .53-.72; ω = .55-.69), retest reliability (r_t1,t2 = .89) at two weeks was high. As expected, we found high correlations with other OCD instruments (r > .61; convergent validity), and significantly weaker correlations with measures of depression (r = .39), health anxiety (r = .29), and health-related well-being (r = -.28, divergent validity). Nonetheless, the correlations with general anxiety were somewhere in between (r = .52).

CONCLUSIONS

Due to heterogeneous OCD subtypes, the ZF-OCS asks diverse questions which probably resulted in the present internal consistency. Nevertheless, the results on retest reliability and validity were promising. As for other OCD instruments, divergent validity regarding general anxiety seems problematic to establish. Even so, the ZF-OCS seems valuable for screening purposes, as it is short and easy to administer, and may facilitate initiating subsequent clinical assessment. Further studies should determine the instrument's diagnostic accuracy.

Transition Cliffs for Young Adults with Anxiety and Depression: Is Integrated Mental Health Care a Solution?

Young adulthood is a major transition period, particularly challenging for those with mental disorders. Though the prevalence of depressive and anxiety disorders is especially high, young adults are less likely to receive mental health treatment than younger and older individuals. Reasons for this mental health treatment gap are multifold and range from individual- to system-level factors that must be taken into consideration when addressing young adult mental health needs. Studies in adults and adolescents have shown that integrated care in primary care settings is an effective model of treatment of mental disorders. After providing an overview of the mental health treatment gap in this developmental period, the argument is made for research focused on integrated care models specifically tailored for young adults that takes into consideration the various needs and challenges that they face and addresses the mental health treatment gap in young adulthood.

Screening and referral is not enough: a qualitative exploration of barriers to access and uptake of mental health services in patients with cardiovascular diseases

Background

Cardiovascular diseases (CVD) are commonly comorbid with mental health disorders, portending poorer cardiac prognosis. Despite the high prevalence of depression and anxiety, and guidelines recommending routine depression screening and referral, uptake of mental healthcare in CVD populations remains low. Reasons for the underutilisation of mental health and psychological services for this population remain largely unknown.

Methods

Thirteen CVD patients with clinically significant psychological symptoms (depression, anxiety and/or stress) participated in one-on-one in-depth semi-structured interviews. Data were analysed using inductive thematic analysis.

Results

Barriers to uptake included the timing of referral and screening, with patients reporting a need for longer term follow-up. A lack of information provision and understanding around mental health and services, especially following cardiac-events were further barriers. A reluctance to report mental health or engage in services was also identified, with patients indicating a preference for informal peer support networks. A range of practical barriers such as mobility, transport and cost were also reported.

Conclusions

Longer term follow-up and routine mental health assessment may be beneficial to facilitate use of mental health services. Upskilling of practitioners around mental health may be a further avenue to promote information provision and enhance service use. Further focus on enhancing informal peer support may be a valuable initial approach for the CVD population. The implications for improving services and enhancing service use are discussed.

Treatment of Heart Failure Patients with Anxiolytics Is Associated with Adverse Outcomes, with and without Depression

BACKGROUND

Few studies have evaluated the effect of pharmacologic treatment of anxiety on outcomes in heart failure (HF) patients. This study examined the impact of treatment with anxiolytics on clinical outcomes in a real-world sample of HF patients with and without depression.

METHODS

Patients diagnosed with HF were retrieved from a large HMO database. Patients prescribed anxiolytic medication and patients diagnosed with depression and/or prescribed anti-depressant medication were followed for cardiac-related hospitalizations and death.

RESULTS

The study cohort included 6293 HF patients. Treatment with anxiolytics was associated with decreased one-year survival compared to untreated individuals, with a greater reduction in survival seen in patients diagnosed with depression and/or treated with anti-depressants. Multi-variable analysis adjusting for age, sex, NYHA class, cardiac risk factors and laboratory parameters found that treatment with anxiolytics remained a predictor of mortality even when adjusting for depression. Depression combined with anxiolytic treatment was predictive of increased mortality, and treatment with anxiolytics alone, depression alone and anxiolytic treatment together with depression were each associated with an increased hazard ratio for a composite outcome of death and hospitalization.

CONCLUSIONS

In this real-world study of HF patients, both treatment with anxiolytics and depression were associated with increased mortality, and anxiolytic therapy remained a predictor of mortality when adjusting for depression. Treatment of anxiety together with depression was associated with the highest risk of mortality. Safe and effective treatment for anxiety and depression is warranted to alleviate the detrimental impact of these disorders on quality and of life and adverse events.

Severity and prevalence of various types of mental ill-health in a general adult population: age and sex differences

BACKGROUND

Taking a broad approach, the aim of this study was to better understand severity and prevalence of various types of mental ill-health across age and sex groups in the general adult population. A first objective was to determine symptom severity of anxiety, depression, insomnia, burnout and somatization in combinations of different age groups and sex. A second objective was to determine prevalence of caseness of these types of mental ill-health in both absolute and relative terms in the combinations of age groups and sex.

METHODS

Cross-sectional data based on validated questionnaire instruments were used from the Västerbotten Environmental Health Study in Sweden. In total, 3406 participants, aged 18 to 79 years, constituted a random sample stratified for age and sex.

RESULTS

Severity and prevalence of anxiety, insomnia and burnout were high in women, in particular young women, and lower in older age groups. The prevalence rates for insomnia, burnout and somatization were particularly high based on the used cut-off scores. Men aged 30-49 years had the highest prevalence of mental ill-health compared to other age groups among men. Men and women aged 60-69 years had generally the lowest symptom severity and caseness. The prevalence of depression was similar in men and women in all age groups, whereas sex-related differences in extent in general were largest in the youngest age group, and gradually decreased with age.

CONCLUSION

The results suggest that focus in primary healthcare regarding mental ill-health should to be directed more towards insomnia, burnout and somatization, in particular in young women.

Recognition of anxiety disorders in children: a cross-sectional vignette-based survey among general practitioners

OBJECTIVE

To quantify general practitioners' (GPs) sensitivity to anxiety disorders (ADs) when confronted with the range of symptoms common to children with ADs. Also, to explore GPs' conscious preferences and implicit tendencies for referral of children with ADs to mental healthcare.

DESIGN AND SETTING

In a cross-sectional vignette-based survey, all attendees of a Dutch continuing medical education conference for primary care physicians were presented with subtitled audio fragments of five vignettes that we constructed to mimic symptom presentation of children with ADs in general practice. We asked attendees to select per vignette the most plausible diagnoses and most adequate referral option, and for their general referral preferences when they suspect each of the most common mental health problems.

PARTICIPANTS

A sample of 229 GPs, resulting in a total of 1128 vignette evaluations.

MAIN OUTCOME MEASURE

GPs' selection rate of ADs in the five vignettes compared with a benchmark provided by mental health professionals (MHPs).

RESULTS

Overall, recognition of ADs was less likely in GPs compared with MHPs (OR=0.26, 95% CI 0.15 to 0.46). GPs varied in their recognition of anxiety, with 44.1% not once selecting anxiety as the probable presenting problem. When asked explicitly, 63.9% of the GPs reported that they would refer a child to mental healthcare when they suspect probable ADs. By contrast, only 12.0% of the GPs who recognised anxiety in the vignettes actually selected that referral option.

CONCLUSION

A significant fraction of GPs did not notice the depicted symptoms as anxiety. Despite the widespread prevalence of ADs, GPs seem to overlook anxiety already in their early diagnostic opinion. Improving GPs' familiarity with initial symptom presentation, ADs' base-rate, relevance and impact yields potential for timely recognition.

Strategies for engaging patients and families in collaborative care programs for depression and anxiety disorders: A systematic review

BACKGROUND

Patients and families are often referred to as important partners in collaborative mental health care (CMHC). However, how to meaningfully engage them as partners remains unclear. We aimed to identify strategies for engaging patients and families in CMHC programs for depression and anxiety disorders.

METHODS

We updated a Cochrane review of CMHC programs for depression and anxiety disorders. Searches were conducted in Cochrane CCDAN and CINAHL, complemented by additional database searches, trial registry searches, and cluster searches for 'sibling' articles. Coding and data extraction of engagement strategies was an iterative process guided by a conceptual framework. We used narrative synthesis and descriptive statistics to report on findings.

FINDINGS

We found 148 unique CMCH programs, described in 578 articles. Most programs (96%) featured at least one strategy for engaging patients or families. Programs adopted 15 different strategies overall, with a median of two strategies per program (range 0-9 strategies). The most common strategies were patient education (87% of programs) and self-management supports (47% of programs). Personalized care planning, shared decision making, and family or peer supports were identified in fewer than one third of programs.

LIMITATIONS

Our search strategy was designed to capture programs evaluated in clinical trials and so other innovative programs not studied in trials were likely missed.

CONCLUSION

Most CMHC programs for depression and anxiety disorders adopted a limited number of strategies to engage patients and families in their care. However, this review identifies numerous strategies that can be used to strengthen the patient- and family-centeredness of collaborative care.

[Educational intervention to improve diagnostic accuracy regarding psychological morbidity in general practice]

INTRODUCTION

The aim of this pilot study was to evaluate the effectiveness of a complex educational intervention to improve the diagnostic competencies of general practitioners (GPs) regarding the detection of depression, anxiety and somatization.

METHODS

Cluster-randomized controlled pilot study with six practices each in the intervention group and in the control group. Psychological morbidity was determined by patient self-report using the Patient Health Questionnaire (PHQ-D). GPs rated the extent of psychological morbidity on a numerical rating scale from 0 (no co-morbidity) to 10 (maximum) of the individual patient after the consultation, independent of the reason for encounter.

RESULTS

364 patients participated. There were moderate correlations between GP rating and the PHQ scales (Spearman correlation between 0.27 and 0.42). There was no significant difference between intervention and control group. Diagnostic accuracy of the GPs, as determined with areas under the curves (AUCs), ranged between 0.52 (95%KI 0.30-0.73) and 0.84 (95%KI 0.67-1.00). The AUCs showed significant heterogeneity (Cochran Q=25.0; p<0.01). The regression analysis with 'presence of psychological disorder' (in PHQ) as the dependent variable showed that longer duration of doctor-patient-relationship was negatively associated with psychological morbidity (OR 0.96; 95%KI 0.92-0.99; p=0.01). There was a significant interaction between the factors 'time of doctor-patient relationship' and 'GP rating' (ß=0.02; OR 1.02, 95%KI 1.01-1.03; p<0.001), pointing towards increasing diagnostic accuracy when patients are known for a longer time.

DISCUSSION

We found no significant effect regarding the educational intervention. The GPs' estimation regarding psychological morbidity correlated significantly with the self-rating of the patients on PHQ scales. However, there was a considerable inter-individual variation between the GPs' diagnostic accuracy. The diagnostic estimation improved with increasing duration of doctor-physician relationship.

CONCLUSION

A one-time educational intervention seems not to be sufficient to improve diagnostic competencies in the detection of psychological morbidity. The considerable variation of the diagnostic accuracy might explain why 'one-size-fits-all' educational interventions will not help improve diagnostic competencies.

Feasibility of referral to a therapist for assessment of psychiatric problems in primary care - an interview study

Background

Depression and anxiety disorders are common in primary care. Comorbidities are frequent, and the diagnoses can be difficult. The Mini-International Neuropsychiatric Interview (MINI) can be a support in the clinical examination of patients with complex problems. However, for family practitioners (FPs), time and perceptions about structured interviews can be barriers to the MINI. An inter-professional teamwork process where FPs refer a patient to a therapist for a MINI assessment represents one way in which to address the problem. The results are fed back to the FPs for diagnosis and treatment decisions.

The purposes of this study were to explore if the process was feasible for FPs, patients and therapists in Swedish primary care, and to identify factors influencing the process, using the COM-B model.

Methods

FPs at two primary care centers (PHCC) in Stockholm were offered the opportunity to refer patients to in-house therapists. Semi-structured interviews or focus groups were conducted with 22 patients, 17 FPs and three therapists to capture their experiences and perceptions. Inductive content analysis for each group of participants was followed by triangulation across groups. Finally, the categories obtained were fitted to the components in the COM-B.

Results

Therapists at both PHCCs conducted the MINI. The intended process was adopted at one PHCC. At the second PHCC, the responsibilities for the diagnosis and treatment of patients referred were transferred to the therapist. The patients were satisfied, as they appreciated multi-professional examinations. The FPs’ competence in psychiatry, actual access to therapists, beliefs that the referrals saved the FPs time and effort, and established habits influenced whether patients were referred. Existing routines and professional expectations for work content influenced the degree of cooperation between the therapists and the FPs.

Conclusions

An inter-professional diagnostic process where FPs refer patients to a therapist for assessment and the results are fed back to the FPs can be feasible. Feasibility depends on access to a therapist, the perceptions of roles and competences among FPs and therapists, and strategies for supporting teamwork.

Can brief alcohol interventions in general hospital inpatients improve mental and general health over 2 years? Results from a randomized controlled trial

BACKGROUND

Little is known about the impact of brief alcohol interventions on mental and general health. The aim was to investigate whether brief interventions for general hospital inpatients with at-risk drinking can improve mental and general health over 2 years; and whether effects are dependent on how they are delivered: in-person or through computer-generated feedback letters (CO).

METHODS

Three-arm randomized controlled trial with 6-, 12-, 18-, and 24-month follow-ups. Data were collected on 13 general hospital wards from four medical departments (internal medicine, surgical medicine, trauma surgery, and ear-nose-throat) of one university hospital in northeastern rural Germany. A consecutive sample of 961 18- to 64-year-old general hospital inpatients with at-risk alcohol use was recruited through systematic screening. Inpatients with particularly severe alcohol problems were excluded. Participants were allocated to: in-person counseling (PE), CO, and assessment only (AO). PE and CO included three contacts: on the ward, 1, and 3 months later. Mental and general health were assessed using the five-item mental health inventory (0-100) and a one-item general health measure (0, poor - 4, excellent).

RESULTS

Latent growth models including all participants revealed: after 24 months and in contrast to AO, mental and general health were improved in PE (change in mean difference, ΔMmental = 5.13, p = 0.002, Cohen's d = 0.51; ΔMgeneral = 0.20, p = 0.005, d = 0.71) and CO (ΔMmental = 6.98, p &lt; 0.001, d = 0.69; ΔMgeneral = 0.24, p = 0.001, d = 0.86). PE and CO did not differ significantly.

CONCLUSIONS

Beyond drinking reduction, PE and CO can improve general hospital inpatients' self-reported mental and general health over 2 years.

The Validity and Reliability of Screening Measures for Depression and Anxiety Disorders in Inflammatory Bowel Disease

BACKGROUND

We evaluated the validity and reliability of multiple symptom scales for depression and anxiety for persons with inflammatory bowel disease (IBD).

METHODS

IBD participants in a cohort study completed a Structured Clinical Interview for DSM-IV-TR Axis I Disorders (SCID) and completed the Patient Health Questionnaire (PHQ-9), Hospital Anxiety and Depression Scale (HADS), Kessler-6 Distress Scale, PROMIS Emotional Distress Depression Short-Form 8a (PROMIS Depression) and Anxiety Short-Form 8a (PROMIS Anxiety), Generalized Anxiety Disorder 7-item Scale, and Overall Anxiety and Severity Impairment Scale. We computed sensitivity, specificity, and positive and negative predictive values for the screening measures with the SCID diagnoses as the reference standard, conducted receiver operating curve (ROC) analysis, and assessed internal consistency and test-retest reliability.

RESULTS

Of 242 participants, the SCID classified 8.7% as having major depression and 17.8% as having anxiety disorders. Among the depression scales, the PHQ-9 had the highest sensitivity (95%). Specificity was generally higher than sensitivity and was highest for the HADS-D (cut-point of 11; 97%). The area under the ROC curve (AUC) did not differ significantly among depression scales. Among the anxiety scales, sensitivity was highest for the PROMIS (79%). Specificity ranged from 82% to 88% for all tools except the HADS-A (cut-point of 8; 65%). The AUC did not differ between depression and anxiety tools.

CONCLUSIONS

Overall, the symptom scales for depression and anxiety were similar in their psychometric properties. The anxiety scales did not perform as well as the depression scales. Alternate cut-points may be more relevant when these scales are used in an IBD sample.

A computerized version of the Patient Health Questionnaire-4 as an ultra-brief screening tool to detect emotional disorders in primary care

BACKGROUND

The Patient Health Questionnaire-4 (PHQ-4) is an ultra-brief self-report consisting of a 2-item depression scale (PHQ-2) and a 2-item anxiety scale (GAD-2). The aim of the present study is to determine the psychometric properties of a computerized version of the PHQ-4 used to detect emotional disorders (anxiety and depression) in the primary care setting.

METHOD

A total of 1052 patients with suspected anxiety, depression, or somatic symptoms were recruited from 28 primary care centres participating in the PsicAP trial and completed the full version of the computerized PHQ. In addition, 178 of these patients also underwent in clinical interviews as a gold standard.

RESULTS

Confirmatory factor analyses showed very good fit indices for a two-factor solution. This model was structurally invariant among the various age and gender groups and internal consistency was acceptable (PHQ-4; α = .83, PHQ-2; α = .86, and GAD-2; α = .76). The best cut-off points to obtain high sensitivity values was 3, on both the PHQ-2 (major depressive disorder) and the GAD-2 (generalized anxiety disorder). The criterion validity (sensitivity and specificity) for the PHQ-2 were .90 and .61 and for the GAD-2, .88 and 0.61.

LIMITATIONS

The study was not designed as a prevalence study. Therefore, does not contain information on patients whose general practitioners do not consider them to suffer emotional disorders.

CONCLUSION

This is the first study to provide evidence for the reliability and validity of a computerized version of the PHQ-4. This computerized tool can be used to detect depression and anxiety in a primary care setting.

Cross-cultural validation of the German version of the Four-Dimensional Symptom Questionnaire (4DSQ) in multimorbid elderly people

PURPOSE

Psychosomatic symptoms and mental health problems are highly prevalent in multimorbid elderly people challenging general practitioners to differentiate between normal stress and psychopathological conditions. The 4DSQ is a Dutch questionnaire developed to detect anxiety, depression, somatization, and distress in primary care. This study aims to analyze measurement equivalence between a German version and the original Dutch instrument.

METHODS

A Dutch and a German sample of multimorbid elderly people, matched by gender and age, were analyzed. Equivalence of scale structures was assessed by confirmatory factor analysis (CFA). To evaluate measurement equivalence across languages, differential item functioning (DIF) was analyzed using Mantel-Haenszel method and hybrid ordinal logistic regression analysis. Differential test functioning (DTF) was assessed using Rasch analysis.

RESULTS

A total of 185 German and 185 Dutch participants completed the questionnaire. The CFA confirmed one-factor models for all scales of both 4DSQ versions. Nine items in three scales were flagged with DIF. The anxiety scale showed to be free of DIF. DTF analysis revealed negligible scale impact of DIF.

CONCLUSIONS

The German 4DSQ demonstrated measurement equivalence to the original Dutch instrument. Hence, it can be considered a valid questionnaire for the screening for mental health problems in primary care.

Treatment gap for anxiety disorders is global: Results of the World Mental Health Surveys in 21 countries

BACKGROUND

Anxiety disorders are a major cause of burden of disease. Treatment gaps have been described, but a worldwide evaluation is lacking. We estimated, among individuals with a 12-month DSM-IV (where DSM is Diagnostic Statistical Manual) anxiety disorder in 21 countries, the proportion who (i) perceived a need for treatment; (ii) received any treatment; and (iii) received possibly adequate treatment.

METHODS

Data from 23 community surveys in 21 countries of the World Mental Health (WMH) surveys. DSM-IV mental disorders were assessed (WHO Composite International Diagnostic Interview, CIDI 3.0). DSM-IV included posttraumatic stress disorder among anxiety disorders, while it is not considered so in the DSM-5. We asked if, in the previous 12 months, respondents felt they needed professional treatment and if they obtained professional treatment (specialized/general medical, complementary alternative medical, or nonmedical professional) for "problems with emotions, nerves, mental health, or use of alcohol or drugs." Possibly adequate treatment was defined as receiving pharmacotherapy (1+ months of medication and 4+ visits to a medical doctor) or psychotherapy, complementary alternative medicine or nonmedical care (8+ visits).

RESULTS

Of 51,547 respondents (response = 71.3%), 9.8% had a 12-month DSM-IV anxiety disorder, 27.6% of whom received any treatment, and only 9.8% received possibly adequate treatment. Of those with 12-month anxiety only 41.3% perceived a need for care. Lower treatment levels were found for lower income countries.

CONCLUSIONS

Low levels of service use and a high proportion of those receiving services not meeting adequacy standards for anxiety disorders exist worldwide. Results suggest the need for improving recognition of anxiety disorders and the quality of treatment.

Anxious Depression and Neurocognition among Middle-Aged and Older Hispanic/Latino Adults: Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Results

OBJECTIVE

The purpose of this study is to examine the association between verbal learning, fluency, and processing speed with anxious depression symptomatology (ADS) among diverse Hispanics. We hypothesized an inverse association of anxious depression with neurocognition among Hispanics of different heritage.

DESIGN

Data are from the Hispanic Community Health Study/Study of Latinos. The sample included 9,311participants aged 45-74 years (mean: 56.5 years). A latent class analysis of items from the Center for Epidemiological Studies for Depression scale and the Spielberger Trait Anxiety Inventory was used to derive an anxious depression construct. Neurocognitive measures included scores on the Brief Spanish English Verbal Learning Test (B-SEVLT, learning and recall trials), Word Fluency (WF), Digit Symbol Substitution (DSS) test, and a Global Cognitive Score (GCS). We fit survey linear regression models to test the associations between anxious depression symptomatology and cognitive function. We tested for effect modification by sex, Hispanic heritage, and age groups.

RESULTS

Among men, 71.6% reported low, 23.3% moderate, and 5.1% high ADS. Among women, 55.1% reported low, 33.2% moderate, and 11.8% high ADS. After controlling for age, sex, sociodemographic characteristics, cardiovascular risk factors and disease, and antidepressant use, we found significant inverse associations between moderate and high anxious depression (ref:low) with B-SEVLT learning and recall, DSS and GCS. Moderate, but not high, anxious depression was inversely associated with WF. Associations were not modified by sex, Hispanic heritage, or age.

CONCLUSIONS

Increased anxious depression symptomatology is associated with decreased neurocognitive function among Hispanics. Longitudinal studies are needed to establish temporality and infer if negative emotional symptoms precede cognitive deficits.

The prevalence of antenatal and postnatal co-morbid anxiety and depression: a meta-analysis

To date, the precise prevalence of co-morbidity of anxiety and depression in the perinatal period is not well known. We aimed to estimate the prevalence of co-morbid anxiety and depression in the antenatal and postnatal periods. Systematic searches of multiple electronic databases were conducted for studies published between January 1950 and January 2016. We included 66 (24 published and 42 unpublished) studies incorporating 162 120 women from 30 countries. Prevalence of self-reported antenatal anxiety symptoms and mild to severe depressive symptoms was 9.5% [95% confidence interval (CI) 7.8-11.2, 17 studies, n = 25 592] and of co-morbid anxiety symptoms and moderate/severe depressive symptoms was 6.3% (95% CI 4.8-7.7, 17 studies, n = 27 270). Prevalence of a clinical diagnosis of any antenatal anxiety disorder and depression was 9.3% (95% CI 4.0-14.7, 10 studies, n = 3918) and of co-morbid generalized anxiety disorder and depression was 1.7% (95% CI 0.2-3.1, three studies, n = 3085). Postnatally between 1 and 24 weeks postpartum, the prevalence of co-morbid anxiety symptoms and mild to severe depressive symptoms was 8.2% (95% CI 6.5-9.9, 15 studies, n = 14 731), while co-morbid anxiety symptoms and moderate/severe depressive symptoms was 5.7% (95% CI 4.3-7.1, 13 studies, n = 20 849). The prevalence of a clinical diagnosis of co-morbid anxiety and depression was 4.2% (95% CI 1.9-6.6, eight studies, n = 3251). Prevalence rates did not differ with regard to year of publication, country income, selection bias and attrition bias. The results suggest that co-morbid perinatal anxiety and depression are prevalent and warrant clinical attention given the potential negative child developmental consequences if left untreated. Further research is warranted to develop evidence-based interventions for prevention, identification and treatment of this co-morbidity.

Health Service Utilisation, Detection Rates by Family Practitioners, and Management of Patients with Common Mental Disorders in French Family Practice

OBJECTIVE

Provide up-to-date detection rates for common mental disorders (CMD) and examine patient service-use since the Preferred Doctor scheme was introduced to France in 2005, with patients encouraged to register with and consult a family practitioner (FP) of their choice.

METHODS

Study of 1133 consecutive patients consulting 38 FPs in the Montpellier region, replicating a study performed before the scheme. Patients in the waiting room completed the self-report Patient Health Questionnaire (PHQ) and Client Service-Receipt Inventory with questions on registration with a Preferred Doctor and doctor-shopping. CMD was defined as reaching PHQ criteria for depression, somatoform, panic or anxiety disorder. For each patient, FPs completed a questionnaire capturing psychiatric caseness.

RESULTS

81.2% of patients were seeing their Preferred Doctor on the survey-day. Of those with a CMD, 52.6% were detected by the FP. This increased with CMD severity and comorbidity. Detected cases were more likely to be consulting their Preferred Doctor (84.7% versus 79.4% for non-detected cases, p = 0.05) rather than another FP. They declared more visits to psychiatrists (17.2% versus 6.7%, p = 0.002). There was no association with consultation frequency or doctor-shopping, which both declined between the two studies.

CONCLUSION

The CMD detection rate is relatively high, with no increase compared to our previous study, despite a decline in doctor-shopping. An explanation is the same high proportion of patients visiting their usual FP on the survey-day at both periods, suggesting a limited impact of the scheme on care continuity. FP action taken highlights the importance of improving detection for providing care to patients with CMDs.

Anxiety disorders and risk of stroke: A systematic review and meta-analysis

BACKGROUND

Anxiety disorders are the most common mental health problem worldwide. However, the evidence on the association between anxiety disorders and risk of stroke is limited. This systematic review and meta-analysis presents a critical appraisal and summary of the available evidence on the association between anxiety disorders and risk of stroke.

METHODS

Cohort studies reporting risk of stroke among patients with anxiety disorders were searched in PubMed, Embase, PsycINFO, Scopus, and the Web of Science, from database inception to June 2016. The quality of the studies was assessed using standard criteria. A meta-analysis was undertaken to obtain pooled estimates of the risk of stroke among patients with anxiety disorders.

RESULTS

Eight studies, including 950,759 patients, from the 11,764 references initially identified, were included in this review. A significantly increased risk of stroke for patients with anxiety disorders was observed, with an overall hazard ratio: 1.24 (1.09-1.41), P=0.001. No significant heterogeneity between studies was detected and the funnel plot suggested that publication bias was unlikely. Limited evidence suggests that the risk of stroke is increased shortly after the diagnosis of anxiety and that risk of stroke may be higher for patients with severe anxiety.

CONCLUSIONS

Anxiety disorders are a very prevalent modifiable condition associated with risk of stroke increased by 24%. This evidence could inform the development of interventions for the management of anxiety and the prevention of stroke. Further studies on the risk of stroke in patients with anxiety, and the explanatory factors for this association, are required.

Interactive effect of negative affectivity and anxiety sensitivity in terms of mental health among Latinos in primary care

From a public health perspective, primary care medical settings represent a strategic location to address mental health disapirty among Latinos. Yet, there is little empirical work that addresses affective vulnerability processes for mental health problems in such settings. To help address this gap in knowledge, the present investigation examined an interactive model of negative affectivity (tendency to experience negative mood states) and anxiety sensitivity (fear of the negative consequences of aversive sensations) among a Latino sample in primary care in terms of a relatively wide range of anxiety/depression indices. Participants included 390 Latino adults (Mage=38.7, SD=11.3; 86.9% female; 95.6% reported Spanish as first language) from a primary care health clinic. Primary dependent measures included depressive, suicidal, social anxiety, and anxious arousal symptoms, number of mood and anxiety disorders, and disability. Consistent with prediction, the interaction between negative affectivity and anxiety sensitivity was significantly related to suicidal, social anxiety, and anxious arousal symptoms, as well as number of mood/anxiety diagnoses and disability among the primary care Latino sample. The form of the interactions indicated a synergistic effect, such that the greatest levels of each outcome were found among those with high negative affectivity and high anxiety sensitivity. There was a trending interaction for depressive symptoms. Overall, these data provide novel empirical evidence suggesting that there is a clinically-relevant interplay between anxiety sensitivity and negative affectivity in regard to the expression of anxiety and depressive symptoms among a Latino primary care sample.

A qualitative study of perceived needs and factors associated with the quality of care for common mental disorders in patients with chronic diseases: the perspective of primary care clinicians and patients

BACKGROUND

The prevalence of comorbid anxiety and depressive disorders is high among patients with chronic diseases in primary care, and is associated with increased morbidity and mortality rates. The detection and treatment of common mental disorders in patients with chronic diseases can be challenging in the primary care setting. This study aims to explore the perceived needs, barriers and facilitators for the delivery of mental health care for patients with coexisting common mental disorders and chronic diseases in primary care from the clinician and patient perspectives.

METHODS

In this qualitative descriptive study, we conducted semi-structured interviews with clinicians (family physician, nurse, psychologist, social worker; n = 18) and patients (n = 10) from three primary care clinics in Quebec, Canada. The themes explored included clinician factors (e.g., attitudes, perception of roles, collaboration, management of clinical priorities) and patient factors (e.g., needs, preferences, access to care, communication with health professionals) associated with the delivery of care. Qualitative data analysis was conducted based on an interactive cyclical process of data reduction, data display and conclusion drawing and verification.

RESULTS

Clinician interviews highlighted a number of needs, barriers and enablers in the provision of patient services, which related to inter-professional collaboration, access to psychotherapy, polypharmacy as well as communication and coordination of services within the primary care clinic and the local network. Two specific facilitators associated with optimal mental health care were the broadening of nurses' functions in mental health care and the active integration of consulting psychiatrists. Patients corroborated the issues raised by the clinicians, particularly in the domains of whole-person care, service accessibility and care management.

CONCLUSIONS

The results of this project will contribute to the development of quality improvement interventions to increase the uptake of organizational and clinical evidence-based practices for patients with chronic diseases and concurrent common mental disorders, in priority areas including collaborative care, access to psychotherapy and linkages with specialized mental health care.
