Enabling lay providers to conduct CBT for older adults: key steps for expanding treatment capacity

Strategies to improve access to cognitive behavioral therapies for anxiety disorders: A scoping review

Background

Strategies to improve access to evidence-based psychological treatments (EBPTs) include but are not limited to implementation strategies. No currently available framework accounts for the full scope of strategies available to allow stakeholders to improve access to EBPTs. Anxiety disorders are common and impactful mental conditions for which EBPTs, especially cognitive-behavioral therapies (CBT), are well-established yet often hard to access.

Objective

Describe and classify the various strategies reported to improve access to CBT for anxiety disorders.

Methods

Scoping review with a keyword search of several databases + additional grey literature documents reporting on strategies to improve access to CBT for anxiety disorders. A thematic and inductive analysis of data based on grounded theory principles was conducted using NVivo.

Results

We propose to classify strategies to improve access to CBT for anxiety disorders as either "Contributing to the evidence base," "Identifying CBT delivery modalities to adopt in practice," "Building capacity for CBT delivery," "Attuning the process of access to local needs," "Engaging potential service users," or "Improving programs and policies." Each of these strategies is defined, and critical information for their operationalization is provided, including the actors that could be involved in their implementation.

Implications

This scoping review highlights gaps in implementation research regarding improving access to EBPTs that should be accounted for in future studies.

Community-Based Outreach and Treatment for Underserved Older Adults With Clinically Significant Worry: A Randomized Controlled Trial

OBJECTIVE

To determine whether Calmer Life (CL) improved worry, generalized anxiety disorder-related (GAD-related) symptoms, anxiety, depression, sleep, trauma-related symptoms, functional status, and quality of life better than Enhanced Community Care with Resource Counseling (ECC-RC) at 6 months and 9 months.

METHODS

A randomized, controlled, comparative-effectiveness study involving underserved, low-income, mostly minority neighborhoods in Houston, Texas, looked at individuals ≥50 with significant worry and interest in psychosocial treatment. Interventions were CL, cognitive behavioral therapy with resource counseling, facilitation of communication with primary care providers about worry/anxiety, integration of religion/spirituality, person-centered skill content and delivery and nontraditional community providers, ECC-RC, and enhanced standard community-based information/ resource counseling addressing basic unmet and mental health needs. Primary outcomes were worry and GAD-related symptom severity. Secondary outcomes were anxiety, depression, sleep difficulties, trauma-related symptoms, functional status, quality of life, service use and satisfaction.

RESULTS

Similar, moderate improvements followed CL and ECC-RC on worry, GAD-related symptoms, anxiety, depression, sleep, trauma-related symptoms, and mental health quality of life at 6 and 9 months, but with symptoms at both times and higher satisfaction with CL at both. Fewer ECC-RC participants reported a hospital admission in the prior 3 months than those in CL at 6 and 9 months; at 9 months, fewer reported a visit with a provider in the previous 3 months.

CONCLUSION

Both interventions showed similar improvements at 6 and 9 months, but symptoms remained that might require care. Either intervention or a combination may be useful for low-income older adults with identified worry/anxiety.

A meta-analysis of the effect of therapist experience on outcomes for clients with internalizing disorders

Objective: This meta-analysis synthesized the literature regarding the effect of therapist experience on internalizing client outcomes to evaluate the utility of lay providers in delivering treatment and to inform therapist training. Method: The analysis included 22 studies, contributing 208 effect sizes. Study and client characteristics were coded to examine moderators. We conducted subgroup meta-analyses examining the relationship of therapist experience across a diverse set of internalizing client outcomes. Results: Results demonstrated a small, but significant relationship between therapist experience and internalizing client outcomes. There was no relationship between therapist experience and outcomes in clients with primary anxiety disorders. In samples of clients with primary depressive disorders and in samples of clients with mixed internalizing disorders, there was a significant relationship between experience and outcomes. The relationship between therapist experience and outcomes was stronger when clients were randomized to therapists, treatment was not manualized, and for measures of client satisfaction and "other" outcomes (e.g., dropout). Conclusions: It appears that therapist experience may matter for internalizing clients under certain circumstances, but this relationship is modest. Continuing methodological concerns in the literature are noted, as well as recommendations to address these concerns.

Expanding the geriatric mental health workforce through utilization of non-licensed providers

OBJECTIVES

We evaluate policy and practice strategies for bolstering the geriatric mental healthcare workforce and describe costs and considerations of implementing one approach.

METHOD

Narrative overview of the literature and policy retrieved from searches of databases, hand searches, and authoritative texts. We identified three proposed strategies to increase the geriatric mental healthcare workforce: (1) production of more geriatric mental health providers; (2) team-based care; and (3) non-licensed providers. We evaluate each in terms of challenges and potential and provide estimates of costs, policy, and practice considerations for training, employing, and supervising non-licensed mental health providers.

RESULTS

Use of non-licensed providers is key to reforms needed to allow a more older adults to access necessary mental healthcare. Licensed and non-licensed providers have achieved similar improvements for generalized anxiety disorder among patients, although non-licensed providers did so at a lower cost.

CONCLUSION

Supervised non-licensed providers can extend the reach of licensed providers for specific mental health conditions, resulting in lower costs and increased number of patients treated. Although several barriers to implementation exist, policy and infrastructure changes that may support this type of care delivery model are emerging from reforms in financing and associated delivery initiatives created by the Affordable Care Act.

Calmer Life: A Hybrid Effectiveness-implementation Trial for Late-life Anxiety Conducted in Low-income, Mental Health-Underserved Communities

OBJECTIVE

Anxiety is common among older adults and is associated with multiple negative outcomes. Late-life anxiety is usually unrecognized by providers and undertreated, although evidence supports the effectiveness of psychosocial treatment. Access to mental health care is especially poor among African American seniors. New treatment models are needed to expand the reach of mental health care to minority elders.

METHODS

Our article outlines a study designed to test the effectiveness and implementation potential of Calmer Life (CL), a community-based, person-centered, flexible and culturally tailored intervention for late-life anxiety and worry, offered in low-income, mental health-underserved and predominantly African American communities. CL is skills-based, but also includes resource counseling and an option to integrate religion/spirituality. The study population includes individuals 50 years of age and older who are experiencing high levels of worry. The program was developed in the context of a community-academic partnership with organizations that provide services for seniors in underserved communities, and it trains nontraditional community providers to deliver the intervention.

RESULTS

Study progress to date, challenges, and lessons learned are discussed. Data collection is ongoing, and study findings will be available in late 2017.

CONCLUSIONS

CL will offer valuable information to help expand the reach of anxiety treatment among minority seniors living in underserved neighborhoods.

Cognitive behavior therapy for late-life generalized anxiety disorder delivered by lay and expert providers has lasting benefits

OBJECTIVE

Peaceful Living, a cognitive-behavioral treatment (CBT) for late-life generalized anxiety disorder (GAD), produced positive outcomes in GAD severity, anxiety, depression, insomnia, and mental health quality of life relative to usual care with treatment delivered by either bachelor-level lay providers (BLPs) or PhD-level expert providers (PLPs). We examined long-term maintenance of gains during 12 months following CBT for patients in this trial who received the intervention delivered by BLPs and PLPs and completed post-treatment assessments.

METHODS

Participants were 112 older adults (mean age, 66.83 years) with GAD recruited from primary care who received CBT from BLPs (n = 52) or PLPs (n = 60) and completed post-treatment assessments. Assessments were given at post-treatment and at 6- and 12-month follow-up. Primary outcomes assessed long-term maintenance of gains in worry (Generalized Anxiety Disorder Severity Scale) and anxiety (State-Trait Anxiety Inventory, Structured Interview Guide for the Hamilton Anxiety Scale). Secondary outcomes assessed depression (Patient Health Questionnaire), mental health quality of life (Medical Outcomes Study Short Form - mental wellness scale), and sleep (Insomnia Severity Index).

RESULTS

At 6- and 12-month follow-ups, post-treatment reductions in GAD severity, anxiety, depression, and improvements in mental health quality of life and sleep were maintained for patients in both groups. No differences were found, based on provider group.

CONCLUSION

Treatment of late-life anxiety delivered by nonexpert lay providers working under supervision of licensed providers has lasting benefits. These findings support the potential of new models of care for older adults that may expand reach of mental health services. Copyright © 2016 John Wiley & Sons, Ltd.

Calmer Life: A Culturally Tailored Intervention for Anxiety in Underserved Older Adults

OBJECTIVES

To evaluate the feasibility of the Calmer Life and Enhanced Community Care interventions delivered by community and expert providers and test their preliminary effectiveness on worry, generalized anxiety disorder (GAD) severity, anxiety, depression, sleep, health-related quality of life, and satisfaction.

DESIGN

Small randomized trial, with measurements at baseline and 3 months.

SETTING

Underserved, low-income, mostly minority communities in Houston, TX.

PARTICIPANTS

Forty underserved adults 50 years and older, with significant worry and principal or coprincipal GAD or anxiety disorder not otherwise specified.

INTERVENTION

Combination of person-centered, flexible skills training to reduce worry; resource counseling to target unmet basic needs; and facilitation of communication with primary care providers developed through a community-academic partnership with social service and faith-based organizations. Religion/spirituality may be incorporated.

PRIMARY OUTCOMES

worry (Penn State Worry Questionnaire-Abbreviated), GAD severity (GAD-7), anxiety (Geriatric Anxiety Inventory-Short Form).

SECONDARY OUTCOMES

depression (Patient Health Questionnaire-8 and Geriatric Depression Scale-Short Form), sleep (Insomnia Severity Index), health-related quality of life (12-item Medical Outcomes Study Short Form), satisfaction (Client Satisfaction Questionnaire and exit interviews).

RESULTS

Provider training was valid; mean ratings for community providers were well above average, with none less than adequate. Reach was excellent. Participants receiving the Calmer Life intervention had greater improvement in GAD severity and depression than those receiving Enhanced Community Care. Satisfaction with both treatments was equivalent.

CONCLUSIONS

A larger comparative-effectiveness trial needs to examine outcomes following the Calmer Life intervention relative to standard community-based care and to evaluate more fully issues of implementation potential.

Predictors of CBT outcome in older adults with GAD

The current study is a secondary analysis of data from a randomized controlled trial of CBT for late-life GAD (Stanley et al., 2014) which provided an opportunity to examine predictors of outcome among those who received CBT. Participants were 150 older adults who were randomized to receive 10 sessions of CBT. Completer analyses found that homework completion, number of sessions attended, lower worry severity, lower depression severity, and recruitment site predicted 6-month worry outcome on the PSWQ-A, whereas homework completion, credibility of the therapy, lower anxiety severity, and site predicted 6-month anxiety outcome on the STAI-T. In intent-to-treat multivariate analyses, however, only initial worry and anxiety severity, site, and number of sessions completed predicted treatment outcome. These results are largely consistent with predictors of outcome in younger adults and suggest that lower initial symptom severity and variables consistent with greater engagement in treatment predict outcome.
