Brief Screening Tool for Stepped-Care Management of Mental and Substance Use Disorders

Providers' perspectives of barriers and facilitators to scale-up of mental health care in the public health delivery system of Mozambique: a qualitative inquiry

BACKGROUND

A central challenge to closing the mental health treatment gap in low- and middle-income countries (LMICs) is determining the most effective pathway for delivering evidence-based mental health services. We are conducting a cluster-randomized, Type 2 hybrid implementation-effectiveness trial across 20 districts of Mozambique called the Partnerships in Research to Implement and Disseminate Sustainable and Scalable EBPs (PRIDE) program. Following training of nonspecialized providers in facilitation of evidence-based treatments for mental health and informed by the Consolidated Framework for Implementation Research (CFIR), we identified how PRIDE compares to care as usual and the perceived barriers and facilitators of implementation and modifications needed for widescale service delivery and scale-up.

METHODS

We conducted rapid ethnographic assessment using freelisting among 34 providers, followed by four focus group discussions (n = 29 participants) with a subsample of psychiatric technicians and primary care providers from 14 districts in Nampula Province. We used Thematic Analysis to inductively apply open codes to transcripts and then deductively applied the CFIR domains and constructs to organize open codes.

RESULTS

The main Outer Setting constructs relevant to implementation were recognition that patient mental health needs were significant. Additionally, numerous community-level characteristics were identified as barriers, including distance between clinics; shortage of providers; and low awareness of mental health problems, stigma, and discrimination among community members towards those with mental health struggles. The PRIDE program was perceived to offer a relative advantage over usual care because of its use of task-sharing and treating mental illness in the community. PRIDE addressed Inner Setting barriers of having available resources and training and provider low self-efficacy and limited knowledge of mental illness. Providers recommended leadership engagement to give support for supervision of other task-shared professionals delivering mental healthcare.

CONCLUSIONS

Primary care providers and psychiatric technicians in Mozambique perceived the relative advantage of the PRIDE program to address mental health treatment access barriers and offered recommendations for successful sustainment and scale up of integrated mental health care.

Psychometric Evaluation of Screens for Common Mental Disorders, Severe Mental Disorders, Substance Use Disorders, and Suicide Risk in Mozambican Healthcare

Globally, mental and substance use disorders are a leading cause of disease burden. In low- and middle-income countries, where there is an extreme shortage of trained mental health specialists, validated, brief screening tools for mental and substance use disorders are required for non-specialists to efficiently identify patients in need of mental health care. Mozambique, one of the poorest countries in the world, has fewer than two mental health specialists for every 100,000 people. In the present study, we evaluated a comprehensive set of seven measures for depression, anxiety, somatization, alcohol use disorder, substance use disorder, psychosis and mania, and suicide risk among N=911 Mozambican adults in general healthcare settings. All instruments demonstrated acceptable internal consistency (α > 0.75). Compared to diagnoses made by the Mini International Neuropsychiatric Interview, all measures showed good criterion validity (AUC > 0.75), except the Psychosis Screening Questionnaire, which showed low sensitivity (0.58) for psychotic disorder. No substantial differences were observed in internal consistency when stratifying by gender, age, education level, primary language, facility-type, and patient status; criterion validity showed some variability when stratified by sub-population, particularly for education, primary language, and whether the participant was seeking care that day. Exploratory factor analyses indicated that the measures best differentiate categories of diagnoses (common mental disorder, severe mental disorders, substance use disorders, and suicide risk) rather than individual diagnoses, suggesting the utility of a transdiagnostic approach. Our findings support the use of these measures in Mozambique to identify common mental disorders, substance use disorders, and suicide risk, but indicate further research is needed to develop an adequate screen for severe mental disorders. Given the limited mental health specialists in this and other LMIC settings, these brief measures can support non-specialist provision of mental health services and promote closure of the treatment gap.

Lessons From Low- and Middle-Income Countries: Alleviating the Behavioral Health Workforce Shortage in the United States

The United States is facing a mental health workforce shortage, exacerbated by the COVID-19 pandemic. Low- and middle-income countries (LMICs) have historically grappled with even greater shortages. Therefore, LMICs have thought creatively about expanding the mental health workforce and the settings in which to deliver evidence-based and equitable mental health care. The authors introduce some mental health interventions in LMICs, describe evidence of the efficacy of these interventions gleaned from this context, and discuss the applicability of these interventions to the United States. The authors also reflect on the benefits and challenges of implementing these interventions in the U.S. mental health care system to alleviate its current workforce shortage.

Factors influencing integration of mental health screening and treatment at HIV clinic settings in Cameroon: a qualitative study of health providers' perspectives

BACKGROUND

Mental disorders are common among people with HIV (PWH) and are associated with poor HIV outcomes. Despite high unmet mental health needs among PWH, use of evidence-based mental health screening and treatment protocols remains limited at HIV treatment facilities across low-resource settings. Integrating mental health services into HIV care can reduce this gap. This study's objective was to explore factors that influence integration of mental health screening and treatment into HIV clinics in Cameroon.

METHODS

We analyzed 14 in-depth interviews with clinic staff supporting PWH at three urban HIV treatment clinics in Cameroon. Interviews focused on current processes, barriers and facilitators, and types of support needed to integrate mental health care into HIV care. Interviews were recorded and transcribed. French transcripts were translated into English. We used thematic analysis to identify factors that influence integration of mental health screening and treatment into HIV care in these settings. Ethical review boards in the United States and Cameroon approved this study.

RESULTS

Respondents discussed a lack of standardized mental health screening processes in HIV treatment facilities and generally felt ill-equipped to conduct mental health screening. Low community awareness about mental disorders, mental health-related stigma, limited physical space, and high clinic volume affected providers' ability to screen clients for mental disorders. Providers indicated that better coordination and communication were needed to support client referral to mental health care. Despite these barriers, providers were motivated to screen clients for mental disorders and believed that mental health service provision could improve quality of HIV care and treatment outcomes. All providers interviewed said they would feel more confident screening for mental disorders with additional training and resources. Providers recommended community sensitization, training or hiring additional staff, improved coordination to manage referrals, and leadership buy-in at multiple levels of the health system to support sustainable integration of mental health screening and treatment into HIV clinics in Cameroon.

CONCLUSIONS

Providers reported enthusiasm to integrate mental health services into HIV care but need more support and training to do so in an effective and sustainable manner.

Global Is Local: Leveraging Global Mental-Health Methods to Promote Equity and Address Disparities in the United States

Structural barriers perpetuate mental health disparities for minoritized US populations; global mental health (GMH) takes an interdisciplinary approach to increasing mental health care access and relevance. Mutual capacity building partnerships between low and middle-income countries and high-income countries are beginning to use GMH strategies to address disparities across contexts. We highlight these partnerships and shared GMH strategies through a case series of said partnerships between Kenya-North Carolina, South Africa-Maryland, and Mozambique-New York. We analyzed case materials and narrative descriptions using document review. Shared strategies across cases included: qualitative formative work and partnership-building; selecting and adapting evidence-based interventions; prioritizing accessible, feasible delivery; task-sharing; tailoring training and supervision; and mixed-method, hybrid designs. Bidirectional learning between partners improved the use of strategies in both settings. Integrating GMH strategies into clinical science-and facilitating learning across settings-can improve efforts to expand care in ways that consider culture, context, and systems in low-resource settings.

Leveraging a Digitized Mental Wellness (DIGImw) Program to Provide Mental Health Care for Internally Displaced People

A local insurgency has displaced many people in the northern Mozambican province of Cabo Delgado. The authors' global team (comprising members from Brazil, Mozambique, South Africa, and the United States) has been scaling up mental health services across the neighboring province of Nampula, Mozambique, now host to >200,000 displaced people. The authors describe how mental health services can be expanded by leveraging digital technology and task-shifting (i.e., having nonspecialists deliver mental health care) to address the mental health needs of displaced people. These methods can serve as a model for other researchers and clinicians aiming to address mental health needs arising from humanitarian disasters in low-resource settings.

Validation of a brief screener for broad-spectrum mental and substance-use disorders in South Africa

In low-resource settings, valid mental health screening tools for non-specialists can be used to identify patients with psychiatric disorders in need of critical mental health care. The Mental Wellness Tool-13 (mwTool-13) is a 13-item screener for identifying adults at risk for common mental disorders (CMDs) alcohol-use disorders (AUDs), substance-use disorders (SUD), severe mental disorders (SMDs), and suicide risk (SR). The mwTool-13 is administered in two steps, specifically, only those who endorse any of the initial three questions receive the remaining ten questions. We evaluated the performance of mwTool-13 in South Africa against a diagnostic gold standard. We recruited a targeted, gender-balanced sample of adults, aged ≥18 years at primary and tertiary healthcare facilities in Eastern Cape Province. Of the 1885 participants, the prevalence of CMD, AUD, SMD, SR, and SUD was 24.4%, 9.5%, 8.1%, 6.0%, and 1.6%, respectively. The mwTool-13 yielded high sensitivities for CMD, SMD, and SR, but sub-optimal sensitivities for AUD and SUD (56.7% and 64.5%, respectively). Including a single AUD question in the initial question set improved the tool's performance in identifying AUD and SUD (sensitivity > 70%), while maintaining brevity, face-validity, and simplicity in the South African setting.

An Ultra-Brief Proxy Measure for Early Mental and Substance Use Disorders and Suicide Risk Case Detection at the Community and Household Level: An Efficient and Feasible Clinical and Population-level Service Needs Screening Tool

Valid mental and substance use disorders and suicide risk screening tools are needed for community case finding of individuals who may not otherwise seek care. We evaluated the Proxy Mental Wellness Tool-3 (mwTool-3-proxy) a three-item screener that asks about the mental health of another adult, against a diagnostic gold standard in Mozambique and South Africa. The mwTool-3-proxy adapts the three items of the Mental Wellness Tool-3, developed in Mozambique using Mini International Neuropsychiatric Interview diagnoses as the criterion standard, regression modeling and expert consultation to determine the best three items for identifying any mental disorder. The Mental Wellness Tool-3 has been validated in South Africa, Spain and the United States, and is being validated in three countries in the Asia-Pacific and Israel. Pairs of adults in South Africa and Mozambique at primary and tertiary healthcare facilities were separately screened with the mwTool-3-proxy and diagnosed using the Mini International Neuropsychiatric Interview. We calculated the sensitivities and specificities for predicting any mental and/or substance use disorder and suicide risk among the proxy individual. We performed additional analyses restricted to respondents who were relatives of one another and who lived in the same household. The prevalence of any Mini International Neuropsychiatric Interview-diagnosed disorder among the 229 pairs in both countries was 35.6% (38.5% in Mozambique; 32.9% in South Africa). The pooled sensitivity of the mwTool-3-proxy for identifying any disorder among the proxy individual was 73.01 (95%CI: 65.5-79.65) - 70.24 (95%CI: 59.27-79.73) in Mozambique and 80.00 (95%CI 69.17-88.35) in South Africa. The mwTool-3-proxy is a culturally-relevant, ultra-brief valid measure that can improve mental and substance use disorders and suicide risk case detection with strong sensitivity at the community and household level and offer a means to efficiently and feasibly collect clinical and population-level service needs data.

Examination of the Factor Structure of Psychopathology in a Mozambican Sample

Factor-analytic studies are needed in global samples to advance understanding of psychopathology. We aimed to examine the structure of psychopathology and a general psychopathology ('p') factor using data from a cross-sectional study of 971 adults (63% women) from Maputo City, Mozambique. We used confirmatory factor analyses of symptoms from 15 psychiatric disorders to test common models of the structure of psychopathology. Models including internalizing, substance use, and thought disorder factors as well as a general p-factor fit the data well. Measurement invariance testing revealed that factor loadings on p differed by gender. Higher levels of p, internalizing, and thought disorder factors were associated with greater suicide risk, psychiatric comorbidity, chronic medical illnesses, and poorer functioning. A general psychopathology ('p') factor and internalizing, substance use, and thought disorder factors are identifiable in this Mozambican sample. Understanding psychopathology dimensions is a step toward building more scalable mental health service approaches globally.

Association between mental disorders and adherence to antiretroviral treatment in health facilities in two Mozambican provinces in 2018: a cross-sectional study

INTRODUCTION

Lower adherence to antiretroviral treatment (ART) has been found among people with HIV (PWH) who have comorbid mental disorders like depression and alcohol use in Sub-Saharan African. However, there has been less exploration with regards to other mental disorders.

METHODS

This study assessed the association of multiple mental disorders and adherence to ART based on the data from primary/tertiary health care facilities in Maputo and Nampula, Mozambique. We administered a sociodemographic questionnaire, Mini International Neuropsychiatric Interview (MINI) Plus 4.0.0 adapted for use in Mozambique to assess mental conditions, and a 3-item self-report to measure ART adherence.

RESULTS

395 HIV-positive (self-report) participants on ART, with an average age of 36.7 years (SD = 9.8), and 30.4% were male. The most common mental disorders were major depressive disorder (27.34%) followed by psychosis (22.03%), suicidal ideation/behavior (15.44%), and alcohol-use disorder (8.35%). Higher odds of missing at least one dose in the last 30 days (OR = 1.45, 95% CI: 1.01, 2.10) were found in participants with any mental disorder compared to those without a mental disorder. The highest levels of non-adherence were observed among those with drug use disorders and panic disorder.

CONCLUSIONS

In Mozambique, PWH with any co-occurring mental conditions had a lower probability of ART adherence. Integrating comprehensive mental health assessment and treatment and ART adherence interventions tailored to PWH with co-occurring mental disorders is necessary to attain optimal ART adherence and reach the UNAIDS ART target.

The Electronic Mental Wellness Tool as a Self-Administered Brief Screening Instrument for Mental Disorders in the General Spanish Population during the Post-COVID-19 Era

(1) Background: In the "post-COVID-19 era", there is a need to focus on properly assessing and addressing the extent of its well-established mental health collateral damage. The "Electronic Mental Wellness Tool" (E-mwTool) is a 13-item validated stepped-care or stratified management instrument that aims at the high-sensitivity captures of individuals with mental health disorders to determine the need for mental health care. This study validated the E-mwTool in a Spanish-speaking population. (2) Methods: It is a cross-sectional validation study using the Mini International Neuropsychiatric Interview as a criterion standard in a sample of 433 participants. (3) Results: About 72% of the sample had a psychiatric disorder, and 67% had a common mental disorder. Severe mental disorders, alcohol use disorders, substance use disorders, and suicide risk had a much lower prevalence rate (6.7%, 6.2%, 3.2%, and 6.2%, respectively). The first three items performed excellently in identifying any mental health disorder with 0.97 sensitivity. Ten additional items classified participants with common mental disorders, severe mental disorders, substance use disorders, and suicide risk. (4) Conclusions: The E-mwTool had high sensitivity in identifying common mental disorders, alcohol and substance use disorders, and suicidal risk. However, the tool's sensitivity in detecting low-prevalence disorders in the sample was low. This Spanish version may be useful to detect patients at risk of mental health burden at the front line of primary and secondary care in facilitating help-seeking and referral by their physicians.

Psychometric evaluation of the psychosis screening questionnaire in South Africa with attention to overlap between symptoms and normative cultural beliefs

We evaluated the 5-item Psychosis Screening Questionnaire (PSQ) against a diagnostic gold standard in South Africa. 1885 adults at primary and tertiary health facilities were screened with the PSQ and diagnosed using the Mini International Neuropsychiatric Interview-V. Minor adaptations were required of both instruments to distinguish between psychiatric symptoms and normative cultural beliefs. We assessed internal consistency, criterion validity and sensitivities and specificities for identifying current or lifetime hypomanic or manic episode and/or psychotic disorders. The PSQ only yielded acceptable criterion validity for lifetime hypomanic or manic episode. A positive PSQ screen yielded sensitivities of 74.36%, 55.00%, and 64.68% for lifetime hypomanic or manic episode, psychotic disorder, and any SMD, respectively. Given the overlap between symptoms and normative cultural beliefs, preemptive framing was required to improve the cultural understanding and relevance. With these adaptations, the translated PSQ functioned adequately for hypomanic or manic episode, but not for psychotic disorder.

Validation of brief screening instruments for internalizing and externalizing disorders in Mozambican adolescents

BACKGROUND

Mental disorders are the leading cause of disability for youth worldwide. However, there is a dearth of validated, brief instruments to assess mental health in low- and middle-income countries (LMIC). We aimed to facilitate identification of mental disorders in LMIC contexts by adapting and validating measures of internalizing and externalizing disorders for adolescents in Mozambique, an LMIC in southeastern Africa.

METHODS

We selected instruments with good support for validity in high-income and other LMIC settings: the Patient Health Questionnaire Adolescent (PHQ-A), Generalized Anxiety Disorders 7 (GAD-7), and Strengths and Difficulties Questionnaire (SDQ). Instruments were adapted by local and international mental health specialists followed by cognitive interviews (n = 48) with Mozambican adolescents. We administered the instruments along with the Miniature International Neuropsychiatric Interview for Children and Adolescents (MINI-KID)to 485 adolescents aged 12-19 years attending two secondary schools in Maputo City, Mozambique. One week later, we re-administered instruments to a randomly selected sample of 49 adolescents.

RESULTS

Participants were 66.2% (n = 321) female and the average age was 15.9 (S.D = 1.7).Internal consistency (alpha = 0.80, PHQ-A; 0.84, GAD-7; 0.80, SDQ) and test-retest reliabilty (ICC = 0.74, PHQ-A; 0.70, GAD-7; 0.77, SDQ) were acceptabe for the PHQ-A, GAD-7, and the full SDQ. The SDQ internalizing subscale showed poor test-retest reliability (ICC = 0.63) and the SDQ externalizing subscale showed poor internal consistency (alpha = 0.65). All instruments demonstrated good sensitivity and specificity (> 0.70). Youden's index identified optimal cutoff scores of 8 for the PHQ-A, 5 for the GAD-7, 10 for the SDQ internalizing and 9 for the SDQ externalizing subscales, though a range of scores provided acceptable sensitivity and specificity.

CONCLUSIONS

Our data supports reliability and validity of the PHQ-A, GAD-7, and SDQ instruments for rapidly assessing mental health problems in Mozambican adolescents. Use of these tools in other contexts with limited specialists may asist with expanding mental health assessment. Specific instrument and cutoff selection should be based on screening goals, treatment resources, and program objectives.

Partnerships in Research to Implement and Disseminate Sustainable and Scalable Evidence-Based Practices (PRIDE) in Mozambique

BACKGROUND

Mental health conditions impose a major burden worldwide, especially in low- and middle-income countries (LMICs), where health specialists are scarce. A challenge to closing LMICs' mental health treatment gap is determining the most cost-effective task-shifting pathway for delivering mental health services using evidence-based interventions (EBIs). This article discusses the protocol for the first study implementing comprehensive mental health services in LMICs.

METHODS

In partnership with the Mozambican Ministry of Health, this cluster-randomized, hybrid implementation effectiveness type-2 trial will evaluate implementation, patient, and service outcomes of three task-shifting delivery pathways in 20 Mozambican districts (population 4.7 million). In pathway 1 (usual care), community health workers (CHWs) and primary care providers (PCPs) refer patients to district-level mental health clinics. In pathway 2 (screen, refer, and treat), CHWs screen and refer patients to PCPs for behavioral and pharmacological EBIs in community clinics. In pathway 3 (community mental health stepped care), CHWs screen patients and deliver behavioral EBIs in the community and refer medication management cases to PCPs in clinics. Mixed-methods process evaluation will be used to examine factors affecting pathway implementation, adoption, and sustainability. Clinical activities will occur without research team support. Ministry of Health personnel will coordinate training and supervision.

RESULTS

The most cost-effective pathway will be scaled up in all districts for 12 months.

NEXT STEPS

This novel study integrating comprehensive mental health services into primary care will inform a toolkit to help the Mozambican Ministry of Health scale up the most cost-effective pathway for mental health services and can be a template for other LMICs.
