Low-Intensity mental health Support via a Telehealth Enabled Network for adults with diabetes (LISTEN): protocol for a hybrid type 1 effectiveness implementation trial

BACKGROUND

Mental health problems are common among people with diabetes. However, evidence-based strategies for the prevention and early intervention of emotional problems in people with diabetes are lacking. Our aim is to assess the real-world effectiveness, cost-effectiveness, and implementation of a Low-Intensity mental health Support via a Telehealth Enabled Network (LISTEN), facilitated by diabetes health professionals (HPs).

METHODS

A hybrid type I effectiveness-implementation trial, including a two-arm parallel randomised controlled trial, alongside mixed methods process evaluation. Recruited primarily via the National Diabetes Services Scheme, Australian adults with diabetes (N = 454) will be eligible if they are experiencing elevated diabetes distress. Participants are randomised (1:1 ratio) to LISTEN-a brief, low-intensity mental health support program based on a problem-solving therapy framework and delivered via telehealth (intervention) or usual care (web-based resources about diabetes and emotional health). Data are collected via online assessments at baseline (T0), 8 weeks (T1) and 6 months (T2, primary endpoint) follow-up. The primary outcome is between-group differences in diabetes distress at T2. Secondary outcomes include the immediate (T1) and longer-term (T2) effect of the intervention on psychological distress, general emotional well-being, and coping self-efficacy. A within-trial economic evaluation will be conducted. Implementation outcomes will be assessed using mixed methods, according to the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. Data collection will include qualitative interviews and field notes.

DISCUSSION

It is anticipated that LISTEN will reduce diabetes distress among adults with diabetes. The pragmatic trial results will determine whether LISTEN is effective, cost-effective, and should be implemented at scale. Qualitative findings will be used to refine the intervention and implementation strategies as required.

Prevention of sick leave at the workplace: design of a cluster-randomized controlled trial of a problem-solving intervention among employees with common mental disorders

Background

Common mental disorders are highly prevalent in the working population, affecting about 1 in 5 persons in the Organisation for Economic Co-operation and Development countries. About 30% of those affected have a first period of sick leave. Despite several attempts to reduce the risk of sick leave among employees with common mental disorders, there is a lack of knowledge about effective, preventive interventions which aim to reduce such risks. This protocol describes the design of a study to evaluate the effectiveness of a problem-solving intervention delivered by first-line managers to employees with common mental disorders on the prevention of sick leave during the 12-month follow-up.

Methods/design

The study applies a two-armed cluster-randomized trial design of a problem-solving intervention conducted in private-sector companies. First-line managers are randomized into intervention- or control groups by computer-generated random numbers, allocation ratio 1:1. Employees are eligible if at risk for future sick leave due to common mental disorders. These are identified by self-reported psychological health measured by the General Health Questionnaire 12-item, cut-off ≥3, or a positive answer to risk of sick leave.

The intervention is based on problem-solving principles. It involves the training of the first-line managers who then deliver the intervention to employees identified at risk of sick leave. First-line managers in the control group receives a lecture. Primary outcome is number of registered days of sick leave due to common mental disorders during the 12-month follow-up. Secondary outcomes are general health, psychological symptoms, work performance, work ability and psychosocial work environment. A process evaluation will examine the intervention’s reach, fidelity, dose delivered, dose received, satisfaction and context. Research assistants managing the screening procedure, outcome assessors and employees are blinded to randomization and allocation.

Discussion

The study includes analyses of the intervention’s effectiveness and an alongside process evaluation. Methodological strengths and limitations, for example the risk of selection bias, attrition and risk of contamination are discussed.

High vision-related quality of life indices reduce the odds of depressive symptoms in aged care facilities

Objective: To examine the association between vision-related quality of life (VRQoL) and depressive symptoms in residents with vision impairment (VI) in aged care facilities.Methods: In this cross-sectional study using baseline data from a cluster-randomized controlled trial (ACTRN12615000587505) assessing the effectiveness of a novel eye care model, 186 English-speaking residents (mean age 84 years, SD[standard deviation] = 8.7; 33.9% male) with VI and moderate cognitive functioning or better were recruited from 38 facilities across Victoria, Australia. VRQoL was measured using Rasch-transformed scores from the 'Reading'; 'Mobility', and 'Emotional' scales of the Impact of Vision Impairment for Residential Care (IVI-RC) questionnaire. Outcomes were presence of depressive symptoms (binary score: Cornell Scale for Depression in Dementia [CSDD] > 0 vs. CSDD = 0) and severity of depressive symptoms (continuous CSDD score; sample range 1-21). Independent associations with presence and severity of depressive symptoms were examined using zero-inflated logistic and linear multivariable models, respectively.Results: Of the 186 participants, n = 79 (42.5%), n = 94 (50.5%) and n = 13 (7%) reported no, mild (scores 1-7), and clinically significant depressive symptoms (score ≥8), respectively. Better vision-related Mobility (OR = 0.64; 95% CI: 0.44, 0.95, p = 0.02) was associated with reduced odds of depressive symptoms. With every unit improvement in vision-related Reading (β=-0.48; 95% CI: -0.94, -0.01, p = 0.04) and Emotional (β=-0.56; 95% CI: -1.09, -0.02, p = 0.04), severity of depressive symptoms reduced, independent of sociodemographic and medical issues.Conclusion: Better VRQoL was independently associated with reduced depressive symptoms. Supporting older people in aged care to maintain optimal levels of vision-specific functioning, independence, and emotional well-being may protect their mental health.

Knowledge, skills, and attitudes of psychologists working with persons with vision impairment

PURPOSE

Psychologists working with persons with vision impairment face unique challenges in providing psychological services, including mental health care and cognitive assessments. While existing competency guidelines for general disability and rehabilitation psychology are relevant to working with persons with vision impairment in many ways, specific competencies are needed. Previous psychological research into the provision of therapy for persons with vision impairment has focused mainly on communication and intervention strategies and lacks input from the vision-impaired community.

MATERIALS AND METHODS

This qualitative study, grounded in disability, rehabilitation psychology, and competency frameworks aimed to identify the knowledge, skills, and attitudes necessary for psychologists working with persons with vision impairment.

RESULTS

Through triangulating responses from both registered psychologists (N = 10) and persons with vision impairment (N = 5), a thematic analysis identified 29 competencies under six major themes, including: Expertise, Impact, Approach, Collaboration, Assessment, and Flexibility. Competencies were discretely categorized as knowledge, skills, or attitudes.

CONCLUSIONS

This study provides data that may be used as the basis for more rigorous research into identifying areas for vision impaired-specific competency-based training in undergraduate, postgraduate, and professional psychology curricula.Implications for rehabilitationWhilst competencies for disability and rehabilitation psychology already exist, the competencies for psychologists working with persons with vision impairment require updating, informed by both practitioners and clients with vision impairment.These competencies include: knowledge of eye conditions and pathologies; knowledge of the variation in impact of vision loss; general knowledge about vision loss and normal lifespan development; and, the ability to assess the specific impact of vision loss on the individual.Other skills and attitudes, such as oral communication skills and relaying hope and optimism, whilst necessary for all therapeutic encounters, may require particular modification when working with vision-impaired persons.Educators responsible for professional postgraduate courses in psychology should ensure that training incorporates an understanding of the need to modify approaches for particular groups of clients, such as those with vision impairment.

Can we address depression in vision rehabilitation settings? Professionals' perspectives on the barriers to integrating problem-solving treatment

PURPOSE

Low vision rehabilitation (LVR) is a pertinent context for integrating early, evidence-based psychological interventions given the high prevalence of untreated depression in adults with vision impairment. This study aims to identify the perceived barriers and facilitators to staff-delivered telephone-based problem-solving treatment for primary care (PST-PC) offered as an integrated component of LVR.

METHODS

Qualitative semi-structured interviews, developed using the theoretical domains framework (TDF) and Consolidated Framework for Implementation Research (CFIR), were conducted with 21 LVR professionals and a clinical psychologist involved in the delivery of PST-PC. Barriers and facilitators at the practitioner, client, intervention, and organizational level were identified with thematic analysis using a "theoretical" approach.

RESULTS

Prominent barriers were a lack of role recognition for PST-PC practitioners (n = 32), unmet client expectation with PST-PC (n = 28), dissatisfaction with telephone delivery (n = 27), and limited organizational awareness of PST-PC (n = 39). Facilitating factors included a recognized need for evidence-based psychological services (n = 28), clients experiencing benefits in early sessions (n = 38), PST-PC promoting practical skills (n = 26), and comprehensive PST-PC training (n = 36).

CONCLUSIONS

PST-PC may provide an accessible early intervention for LVR clients with depressive symptoms. Ongoing practitioner training, clinical support, and screening potential LVR clients for treatment suitability are likely to enhance delivery in this setting. Implications for rehabilitation Depression is highly prevalent in adults engaged in low vision rehabilitation (LVR) programs, yet few receive support. Clinical guidelines recommend integrated models of care be offered within rehabilitation settings as early intervention for mild to moderate levels of depressive symptoms. Integrated telephone-based problem-solving treatment for primary care (PST-PC) delivered by trained LVR practitioners is a practical, skills-based model that has potential to increase access to an early psychological intervention in LVR clients with depressive symptoms. LVR clients are often older in age, have multiple comorbid health conditions and a significant level of functional disability, requiring flexibility in the delivery of PST-PC and specialized staff training, and support in working with older and more complex clients.
