Improving Retention in Mental Health and Psychosocial Support Interventions: An Analysis of Completion Rates across a Multi-Site Trial with Refugee, Migrant, and Host Communities in Latin America.

Research on mental health and psychosocial support (MHPSS) interventions within refugee and migrant communities has increasingly focused on evaluating implementation, including identifying strategies to promote retention in services. This study examines the relationship between participant characteristics, study setting, and reasons for intervention noncompletion using data from the Entre Nosotras feasibility trial, a community-based MHPSS intervention targeting refugee, migrant, and host community women in Ecuador and Panama that aimed to promote psychosocial wellbeing. Among 225 enrolled women, approximately half completed the intervention, with varying completion rates and reasons for nonattendance across study sites. Participants who were older, had migrated for family reasons, had spent more time in the study community, and were living in Panamá (vs. Ecuador) were more likely to complete the intervention. The findings suggest the need to adapt MHPSS interventions to consider the duration of access to the target population and explore different delivery modalities including the role of technology and cellular devices as reliable or unreliable source for engaging with participants. Engaging younger, newly arrived women is crucial, as they showed lower completion rates. Strategies such as consulting scheduling preferences, providing on-site childcare, and integrating MHPSS interventions with other programs could enhance intervention attendance.

A qualitative evaluation of the use of Problem Management Plus (PM+) among Arabic-speaking migrants with psychological distress in France - The APEX study.

ABSTRACTBackground: Feasibility studies with non-French speaking migrants in France are needed to inform appropriate adaptation of psychosocial intervention procedures.Objective: To test the WHO Problem Management Plus (PM+) intervention protocol for Arabic-speaking migrants in the Paris metropolitan region.Methods: Between 2019 and 2021 we recruited participants from three accommodation centres receiving asylum seekers or migrants experiencing social and economic difficulties. Participants experiencing psychological distress underwent five PM + sessions with trained helpers. Feasibility was evaluated through 15 interviews with 8 participants, 4 helpers, and 3 study supervisors. Interview topics covered PM + implementation in general and for each component. We also sought to understand problems with delivery and gathered suggestions for improvement. Data were analysed thematically using a deductive approach.Results: We found implementation of PM + to be feasible, with predominantly positive reactions from participants, helpers and study staff. All intervention components were considered beneficial, with breathing exercises considered easy to implement and often sustained. Selection of problems and strategies to address them were described as challenging to execute. Psychosocial support from and rapport with helpers and the use of the native language were considered key strengths of the programme. However, we observed the need for complementary or higher intensity psychological support in some cases. Findings also highlighted the importance of addressing distress among non-specialist helpers delivering PM + . Finally, local guidance to social resources were suggested to be added in the protocol.Conclusion: PM + was well-liked and feasible, with cultural adjustments and increased access to community resources for migrants needed.

The World Health Organization Problem Management Plus (PM+) intervention was found to be a feasible and acceptable intervention for Arabic-speaking migrants in the Paris metropolitan region, with participants reporting improved mental health outcomes and satisfaction with the programme.The features of psychosocial support from and rapport with non-specialist helpers delivering PM + and the use of the native language were considered key strengths of the programme.The study documented perceived benefits of expanding PM + in scope and length, suggests the need for additional mental health services for non-specialist helpers, and highlights the importance of considering cultural and linguistic factors when providing mental health services to asylum seekers or migrants experiencing social and economic difficulties.

IMproving psYchosocial adjustment to Traumatic Brain Injury from acute to chronic injury through development and evaluation of the myTBI online psychoeducation platform: protocol for a mixed-methods study.

INTRODUCTION: This protocol describes the myTBI study which aims to: (1) develop an online psychoeducation platform for people with traumatic brain injury (TBI), their family members/caregivers, and healthcare staff to improve psychosocial adjustment to TBI across different phases of injury (acute, postacute, and chronic), and (2) undertake an evaluation of efficacy, acceptability, and feasibility. METHODS AND ANALYSIS: A three-stage mixed-methods research design will be used. The study will be undertaken across four postacute community-based neurorehabilitation and disability support services in Western Australia. Stage 1 (interviews and surveys) will use consumer-driven qualitative methodology to: (1) understand the recovery experiences and psychosocial challenges of people with TBI over key stages (acute, postacute, and chronic), and (2) identify required areas of psychosocial support to inform the psychoeducation platform development. Stage 2 (development) will use a Delphi expert consensus method to: (1) determine the final psychoeducation modules, and (2) perform acceptance testing of the myTBI platform. Finally, stage 3 (evaluation) will be a randomised stepped-wedge trial to evaluate efficacy, acceptability, and feasibility. Outcomes will be measured at baseline, postintervention, follow-up, and at final discharge from services. Change in outcomes will be analysed using multilevel mixed-effects modelling. Follow-up surveys will be conducted to evaluate acceptability and feasibility. ETHICS AND DISSEMINATION: Ethics approval was granted by North Metropolitan Health Service Mental Health Research Ethics and Governance Office (RGS0000005877). Study findings will be relevant to clinicians, researchers, and organisations who are seeking a cost-effective solution to deliver ongoing psychoeducation and support to individuals with TBI across the recovery journey.

Psychoeducational interventions for people living with chronic communicable disease: a systematic review.

OBJECTIVE: Psychoeducation is increasingly recognised for its value in facilitating adaption to a chronic disease diagnosis. This study aimed to synthesise available literature on the psychoeducation interventions available to adults living with chronic communicable disease. METHODS: PubMed, CINAHL, Embase, SocINDEX, PsycINFO and PsycArticles were systematically searched up to May 2023. Peer-reviewed studies, published in English, investigating the impact of psychoeducational interventions on adults living with chronic communicable disease were included, across a range of outcome measures. Narrative synthesis was performed. The Effective Public Health Practice Project tool and Critical Appraisal Skills Programme tool were used to assess risk of bias. RESULTS: In total, 22 studies were included in the review. The majority (n=16) of study populations focused on people living with HIV, followed by hepatitis C (n=5) and genital herpes (n=1). Interventions were delivered online (n=2), via telephone (n=1) and in-person (n=19). The majority of interventions were delivered in group sessions (n=16) and studies emphasised the value of group cohesion for social support, encouraging participants to share their own knowledge in addition to standard didactic presentations. Four studies facilitated peer-led delivery of the psychoeducation. Studies aiming to improve psychological well-being were beneficial in reducing depressive symptoms and/or emotional distress or showed improvement in the participant group overall. There was some evidence to suggest psychoeducation can improve readiness to attend treatment and medication adherence. CONCLUSION: The findings of this review highlight potential benefits of psychoeducation but indicate more robust clinical trials will be required to examine their effectiveness and elucidate the mechanisms by which they best operate. Future interventions incorporating a broader focus on resilience enhancement and coping skills specific to stigmatisation could more comprehensively serve the needs of adults living with chronic communicable disease, particularly with HIV. The role of peer support in group psychoeducation merits further exploration. PROSPERO REGISTRATION NUMBER: CRD42021243058.

A Mobile Instant Messaging-Delivered Psychoeducational Intervention for Cancer Caregivers: A Randomized Clinical Trial.

Importance: Psychoeducational interventions (PEIs), which provide both information and emotional and psychosocial support, may address the unmet needs of the caregivers of adolescent and young adult patients with cancer. Objective: To explore the effects of an instant messaging-delivered PEI on anxiety, depression, quality of life (QOL), and coping and determine whether the intervention reduces caregivers' unmet needs. Design, Setting, and Participants: This randomized clinical trial using an intention-to-treat protocol was conducted from April 1 to September 14, 2022, in a tertiary cancer hospital in China and included caregivers of patients diagnosed with cancer at age 15 to 39 years recruited using convenience sampling. Intervention: Caregivers were allocated 1:1 using a randomized block scheme to the intervention or control group. The intervention group received a 5-week PEI and usual care, whereas the control group received only usual care. The PEI was delivered through articles and calls through an instant messaging application. Main Outcomes and Measures: The primary outcomes were changes in the levels of caregivers' anxiety and depression, measured using the 7-Item Generalized Anxiety Disorder Scale and the Patient Health Questionnaire 9, respectively. The secondary outcomes were changes in the levels of caregivers' QOL, coping, and unmet needs. Results: Of the 160 participants, 92 (57.5%) were male; mean (SD) age was 40.27 (8.33) years. Compared with the control group, the intervention group had significantly greater reduction in severity of anxiety (B = -3.231; 95% CI, -4.746 to -1.716; P < .001) and depression (B = -3.253; 95% CI, -5.052 to -1.454; P < .001), smaller reduction in QOL (B = 13.574; 95% CI, 0.488-26.661; P = .04), and greater reduction in unmet needs (B = -12.136; 95% CI, -18.307 to -5.965; P < .001) after the intervention. Twelve weeks after baseline, the intervention group demonstrated a significantly greater reduction only in severity of anxiety (B = -1.890; 95% CI, -3.382 to -0.397; P = .01). Conclusions and Relevance: In this randomized clinical trial of a mobile instant messaging-delivered PEI, caregivers' unmet needs, anxiety, and depression decreased significantly and QOL declined at a significantly slower rate immediately after the intervention in the intervention group compared with the control group. A sustained effect on anxiety was observed 12 weeks after baseline. Trial Registration: Chinese Clinical Trial Registry identifier: ChiCTR2200055951.

Barriers and Facilitators to Implementing a Community-Based Psychosocial Support Intervention Conducted In-Person and Remotely: A Qualitative Study in Quibdó, Colombia.

Community-based psychosocial support group (CB-PSS) interventions using task-shifting approaches are well suited to provide culturally appropriate services in low- and middle-income countries. However, contextual barriers and facilitators must be considered to tailor interventions effectively, particularly considering the challenges introduced by the COVID-19 pandemic. We explore the barriers, facilitators, and psychosocial changes associated with implementing a CB-PSS group intervention delivered by local lay providers to conflict-affected adults in Quibdó, Colombia, using both in-person and remote modalities. Data were analyzed from 25 individual interviews with participants and a focus group discussion involving staff members, including 7 community psychosocial agent facilitators and 2 mental health professional supervisors. The analysis used a thematic approach grounded in a descriptive phenomenology to explore the lived experiences of participants and staff members during implementation. Participant attendance in the in-person modality was compromised by factors such as competing work and family responsibilities and disruption caused by the COVID-19 pandemic. Participants in the remote modality faced challenges concerning unstable Internet connectivity, recurrent power outages caused by heavy rain, distractions, interruptions, and threats to confidentiality by family and coworkers. Despite these challenges, data revealed key contextual facilitators, including the community-based knowledge of facilitators and integration of traditional practices, such as the comadreo (informal talks and gatherings). Respondents shared that the CB-PSS groups promoted stronger community relationships and created opportunities for participants to exchange peer support, practice leadership skills, develop problem-solving skills based on peers' experiences, and enhance emotional regulation skills. Differences and similarities across in-person and remote modalities are discussed, as are key considerations for practitioners and policymakers.

Considerations and Outcomes for Adolescents and Young Adults With Cloacal Anomalies: A Scoping Review of Urologic, Colorectal, Gynecologic and Psychosocial Concerns.

The objective of this scoping review is to provide a summary of the current literature regarding adolescents and young adults with histories of cloacal anomalies. Preferred Reporting Items for Systematic Reviews and Meta-analysis Extension for Scoping Reviews were used. Data were categorized into four domains-urologic, colorectal, gynecologic/obstetric, and sexual/psychosocial. The current literature has poor study quality and mostly consists of retrospective studies of small cohorts with varying definitions of outcomes. Women with cloacal anomalies are at high risk for urologic dysfunction but can maintain kidney health and achieve social continence with medical and surgical management. Sexual function and adult healthcare transition are areas ripe for improved future research.

How do speech and language therapists enact aphasia psychosocial support in Ireland? A cross-sectional online survey informed by normalization process theory.

BACKGROUND: Supporting psychosocial well-being in aphasia is necessarily person-centred, interdisciplinary and coordinated. Shortcomings in such support are described in Ireland and elsewhere. Speech and language therapists (SLTs) are integral; and describing current practice and barriers they experience is important for enhancing service delivery. AIMS: To understand how SLTs enact, and are supported to enact, aphasia psychosocial care in Ireland. METHODS & PROCEDURES: This is a cross-sectional, online, self-administered clinician survey targeting SLTs working minimally 1 year post-qualification with persons with aphasia of any aetiology in Ireland. The survey questions were charted against key constructs of the implementation science framework, normalization process theory (NPT), and descriptive statistics were applied. OUTCOMES & RESULTS: A total of 54 eligible datasets were included. SLTs believed psychosocial support to be part of their role, but perceived multiple barriers in enacting it. These included a lack of training, clinical supervision, management support, role recognition, and access to and joint working with mental health professionals and services. CONCLUSIONS & IMPLICATIONS: SLTs in Ireland face a range of individual and structural barriers, including care coordination and resourcing. There is a clear need not only for training, upskilling and mentorship, but also for wider changes around access to mental health professionals and clarity around the processes of referral, coordination and integration of aphasia care across settings. These findings comprise preliminary insights into current practices. Further research is needed as well as clarity on best-practice pathways for different aetiologies of aphasia. Articulating current practices using NPT may have utility for developing empirically informed and principled interventions to improve service delivery. WHAT THIS PAPER ADDS: What is already known on this subject People with aphasia of all aetiologies are at risk of psychosocial problems. Shortcomings in access and the availability of appropriate support have been documented both internationally and in Ireland. To address this issue, an important first step is to understand how SLTs in Ireland currently enact and are supported to enact aphasia psychosocial care. What this study adds to the existing knowledge The findings describe the potential levers and barriers to progressing aphasia psychosocial care in Ireland. A range of individual, team and structural factors were identified. These were locally contextualized but similar issues are reported in other countries. Linking attitudes with NPT constructs provides a first step for further principled implementation projects. What are the practical and clinical implications of this study? Addressing psychosocial problems is perceived as a legitimate part of the speech and language therapy role. SLTs in Ireland enact a range of therapeutic approaches but may need opportunities for formal training and supervision, and for better coordination and integration with other mental health services and disciplines. Understanding differences in care pathways across the range of aphasia aetiologies is additionally important given the emphasis on post-stroke aphasia in the literature.

Distress and psychosocial support seeking: A comparison of rural and metropolitan oncology patient experiences.

INTRODUCTION: Prevalence of distress in cancer patients is established at approximately 50%, yet uptake of psychosocial support is minimal. OBJECTIVE: This study aimed to understand why clinically distressed oncology patients choose not to access psychosocial support, including whether this differs by geographic location. It also aimed to determine the proportion of rural and metropolitan patients experiencing clinical levels of distress, and of these, the proportion who do not wish to access support. DESIGN: The study used a cross-sectional design. Two hundred and ninety-eight Australian cancer patients completed an online survey, including the Distress Thermometer and open-ended questions about reasons for declining support. Descriptive statistics and content analysis were used to analyse the data. FINDINGS: More than half (56%) of participants reported experiencing clinically significant levels of distress. Of these, almost half (47%) declined psychosocial support. Content analysis of reasons for declining psychosocial support resulted in six main concepts: I don't need support; I'm using personal resources to cope; negative perceptions and attitudes; life doesn't stop for cancer; I'm focussed on fighting cancer; and systemic barriers. Rural cancer patients most often indicated using personal resources to cope, while metropolitan participants most commonly indicated not needing support. A range of subconcepts were also identified. Perceiving distress as manageable or transient was almost exclusively reported by metropolitan participants, while stigma was almost exclusively reported by rural participants. DISCUSSION: The findings provided greater depth of insight into reasons cancer patients decline psychosocial support and identified several qualitative differences in the reasons provided by metropolitan and rural patients. Recommendations are provided for clinicians, in particular for clinicians who work with rural cancer patients and their supporters. CONCLUSION: These findings can inform equitable resourcing of psychosocial support in rural areas and the adaptation of psychosocial interventions to be more flexible and responsive to individual needs. This may help increase patient uptake of support, particularly in rural areas.

The Effect of Psychosocial Support Videos Provided by the Community on Disease Attitudes and Symptoms of Pediatric Oncology Patients: Randomized Controlled Study.

OBJECTIVE: This study aimed to evaluate the impact of psychosocial support videos provided by the community on the attitudes of pediatric oncology patients aged between 10 and 18 years toward their illness and treatment-related symptoms. DATA SOURCES: This prospective randomized controlled study was conducted with 52 pediatric oncology patients aged between 10 and 18. The data were collected using the Information Form, Child Attitude Towards Illness Scale (CATIS), and Memorial Symptom Assessment Scale (MSAS). When the control group received standard care, the intervention group received psychosocial support videos provided by the community at the beginning of the week for 1 month. CONCLUSION: This study suggests that the implemented intervention positively affected pediatric patients' symptom management, psychological well-being, and attitudes toward their illness. Considering that today's adolescents have grown up in the age of technology and show great interest in technology and media use, it is clear that psychosocial support videos may attract the attention of this age group. Producing and sharing similar content for other children with similar health problems may positively affect the psychosocial health outcomes of pediatric patients. IMPLICATIONS FOR NURSING PRACTICE: It has been found that it is beneficial to include community-supported psychosocial support in the nursing care of pediatric oncology patients. For this reason, it is recommended that nurses actively participate in developing psychosocial support strategies and take the lead in creating and making the content accessible.

A média de idade das mulheres foi de 61,8 anos. Surgiram 4 categorias e 12 subcategorias. Resultados: o diagnóstico de câncer provocou impactos negativos na vida dos pacientes e na vida dos seus familiares. Ter uma rede de apoio é uma importante estratégia de enfrentamento utilizada pelas pacientes, devido ao sofrimento causado pelo câncer. Conclusão:Evidenciou-se a importância de estratégias de enfrentamento do sofrimento do paciente oncológico, sobretudo com relação à rede de apoio, sendo esta a categoria de maior destaque ente todas as encontradas.

Objective: to understand the experiences of cancer patients based on the diagnosis and the strategies adopted. Methods: this is a qualitative and transversal research, exploratory and descriptive. The sample consisted of 10 women with cancer assisted by a support association for cancer patients in João Pessoa/PB, selected by non-probabilistic convenience sampling. To collect data, a sociodemographic and health questionnaire was used, as well as a semi-structured interview based on the life history method. Sociodemographic data were analyzed using descriptive statistics (frequency and percentage), and data from the interview were analyzed using the Thematic Content Analysis technique proposed by Bardin. The average age of the women was 61.8 years. Four categories and 12 subcategories emerged. Results: the diagnosis of cancer caused negative impacts on the lives of patients and their families. Having a support network is an essential coping strategy used by patients due to the suffering caused by cancer. Conclusion: The importance of strategies for coping with the suffering of cancer patients was highlighted, especially concerning the support network, this being the most prominent category among all those found.

Dificuldades percebidas por estudantes de enfermagem da Guiné-Bissau em ensino clínico / Difficulties perceived by nursing students in Guinea-Bissau in clinical teaching

A formação graduada de enfermeiros na Guiné-Bissau encontra-se em processo de transformação, acompanhando o desenvolvimento técnico, científico e pedagógico operado a nível internacional. Esta formação caracteriza-se por períodos de ensino na escola, com aulas teóricas, teórico-práticas e práticas laboratoriais, com alternância entre períodos de ensino clínico em diferentes instituições e serviços de saúde. A transição dos estudantes da escola para o contexto real da prática clínica é, muitas das vezes, marcada por sentimentos angústia e receio. Torna-se assim oportuno compreender as principais dificuldades percebidas por estudantes de enfermagem da Guiné-Bissau no processo de socialização profissional operado em contexto clínico. Trata-se de um estudo descritivo de natureza interpretativa, com o objetivo principal de conhecer a perceção dos estudantes sobre as dificuldades em contexto de ensino clínico, de forma a responder à questão de investigação: ?quais as dificuldades percebidas por estudantes de enfermagem da Guiné-Bissau em ensino clínico??. Contou-se com a participação de 39 estudantes do 2.º ano do Curso Geral de Enfermagem da Escola Nacional de Saúde da Guiné-Bissau, que já tinham realizado ensino clínico e que acederam participar no estudo. Recorreu-se ao inquérito por questionário para recolha de informação. Os resultados deste estudo demostram que existem dificuldades percebidas pelos estudantes de enfermagem da Escola Nacional de Saúde da Guiné-Bissau, nomeadamente, a falta de apoio emocional, o medo, a má logística e alojamento, inexistência de materiais e instrumentos de trabalho nos hospitais, por vezes influenciadas por professores e enfermeiros que os acompanham no ensino clínico, em virtude das suas marcadas dificuldades. Esperamos subsidiar o conhecimento sobre os processos de ensino, de aprendizagem e de avaliação dos estudantes de Enfermagem da Guiné-Bissau, contribuindo para a definição de estratégias de supervisão das aprendizagens mais adequadas e, para a planificação de formação específica para os seus supervisores.

"It just made me feel better": qualitative examination of the implementation of a novel virtual psychosocial support program for adolescents with cancer.

PURPOSE: Adolescents with cancer routinely report feelings of isolation and exclusion, including from medical decision-making. To address this problem and support adolescents, we designed and implemented the novel, virtual, weekly Teens4Teens peer support group and patient education program. We examined the views of participating adolescents, program guest speakers, and program moderators as they pertained to the need for the program, its feasibility, acceptability, and perceived impact. METHODS: We recruited all available adolescents, moderators, and guest speakers who participated in Teens4Teens to take part in audio-recorded, semi-structured interviews. Interviews were transcribed, coded, and analyzed using thematic analysis. RESULTS: We conducted 21 interviews across participant groups. We identified four broad themes: pathways into the Teen4Teens program, Teens4Teens implementation capacity, perspectives of the positive impact of Teens4Teens, and suggestions to improve Teens4Teens. These themes described a perceived need for adolescent-centered psychosocial programming in pediatric cancer care, provided lessons on how best to build and apply such a program, and highlighted the value of the program for both adolescents' and clinicians' acceptability, feasibility, and perceived utility. CONCLUSION: Adolescents, guest speakers, and moderators valued Teens4Teens and made suggestions to improve capacity to routinely implement the program. Adolescent-tailored psychosocial programming, such as Teens4Teens, is positioned to be integrated into clinical care with relative ease and may serve to improve the cancer care experience of adolescents and their families. This study has potential to provide researchers and clinicians with valuable information about the content, design, and delivery of virtual peer support programming for adolescents with cancer.

Bringing mental health to the frontlines: A proactive team-based model for healthcare workers during the COVID-19 pandemic.

OBJECTIVE: A novel team-based service was developed at the beginning of the pandemic in which sixty liaisons were assigned to provide proactive, tailored psychological support for healthcare workers (HCWs) across three of NewYork-Presbyterian's Weill Cornell affiliated hospitals. METHOD: The program took the proactive approach of bringing mental health awareness to every department and major division that interfaced with COVID-19 patients. Virtual and in-person team-based "town hall" meetings were offered to provide psychoeducation, facilitate discussion, foster adaptive coping and social cohesion, and identify employees who would benefit from further individualized support. RESULTS: The program's success was reflected in the number of town halls (1000+) and attendees (6000+) and in qualitative feedback from departments who requested ongoing services. CONCLUSIONS: This article presents the development, implementation, challenges, and opportunities in designing a team-based support model for HCWs. This model may be useful for organizations that seek to develop similar programs.

Strategies to improve the quality and usefulness of mental health trials in humanitarian settings.

A striking rise in the number of people affected by humanitarian crises has led to an increase in mental health and psychosocial support interventions to reduce the psychological effects of such crises. In a parallel trend, researchers have brought increased methodological rigour to their evaluation of these interventions. However, several methodological issues still constrain the quality and real-world relevance of the existing evidence base. We examine five core challenges in randomised controlled trials of mental health and psychosocial support interventions with conflict-affected and disaster-affected populations. These challenges are: translating intervention effects into metrics of real-world significance; giving adequate consideration to the selection and monitoring of control conditions; following rigorous processes to ensure outcome measures are culturally appropriate and psychometrically sound; ensuring and monitoring implementation variables, including fidelity, exposure, participant engagement, and the competence of implementation staff; and assessing mechanisms of change.
