Effectiveness of Cognitive/Behavioral Small Group Intervention for Reduction of Depression and Stress in Non-Hispanic White and Hispanic/Latino Women Dementia Family Caregivers: Outcomes and Mediators of Change

A rank ordering and analysis of four cognitive-behavioral stress-management competencies suggests that proactive stress management is especially valuable

The main objective of this study was to determine the relative value of four cognitive-behavioral competencies that have been shown in empirical studies to be associated with effective stress management. Based on a review of relevant psychological literature, we named the competencies as follows: Manages or Reduces Sources of Stress, Manages Thoughts, Plans and Prevents, and Practices Relaxation Techniques. We measured their relative value by examining data obtained from a diverse convenience sample of 18,895 English-speaking participants in 125 countries (65.0% from the U.S. and Canada) who completed a new inventory of stress-management competencies. We assessed their relative value by employing a concurrent study design, which also allowed us to assess the validity of the new instrument. Regression analyses were used to rank order the four competencies according to how well they predicted desirable outcomes. Both regression and factor analyses pointed to the importance of proactive stress-management practices over reactive methods, but we note that the correlational design of our study has no implications for the possible causal effects of these methods. Questionnaire scores were strongly associated with self-reported happiness and also significantly associated with personal success, professional success, and general level of stress. Data were collected between 2007 and 2022, but we found no effect for time. The study supports the value of stress-management training, and it also suggests that moderate levels of stress may not be as beneficial as previously thought.

Non-pharmacological interventions to improve mental health outcomes among female carers of people living with a neurological condition: a systematic review

PURPOSE

This systematic review aims to examine the effectiveness of non-pharmacological interventions for improving mental health outcomes among female carers of people living with a neurological condition.

MATERIALS AND METHODS

A narrative synthesis of English-language randomized controlled trials was undertaken.

RESULTS

18 unique studies were included. Intervention components that were found to have improved mental health outcomes were: delivered in person, to groups, on an intermittent schedule with ≥10 sessions; had a duration between 3-6 months; and were facilitated by research staff or allied health professionals. As the review had few robust studies, results of mental health outcomes reported in studies assessed as low risk of bias were highlighted in the review. Psychoeducation interventions, cognitive behavioural interventions, and support group interventions were found to improve depression. Psychoeducation interventions were also found to improve burden.

CONCLUSIONS

There is a clear need for adequately powered, high-quality randomised controlled trials to determine the effectiveness of non-pharmacological interventions for female carers of people living with a neurological condition.

Efficacy of a Resourcefulness Intervention to Enhance the Physical and Mental Health of Parents Caring for Technology-dependent Children at Home: A Randomized Controlled Trial

INTRODUCTION

Parent caregivers of children who require lifesaving medical technology (e.g., mechanical ventilation, feeding tubes) must constantly maintain vigilance. Poor physical and psychological health can negatively impact their ability to do so.

METHOD

A two-arm randomized controlled trial was conducted with 197 parent caregivers of technology-dependent children (aged < 18 years) to test the efficacy of Resourcefulness Training1, a cognitive-behavioral intervention that teaches social (help-seeking) and personal (self-help) resourcefulness skills, in improving key outcomes including mental health-related quality of life (HRQOL), depressive cognitions and symptoms, perceived and physiological chronic stress, burden, and physical HRQOL at five-time points.

RESULTS

Mixed-effects models using the intent-to-treat principle indicated statistically significant improvement with intervention participants at six and/or nine months postintervention for depressive cognitions, perceived stress, and physical HRQOL, controlling for covariates.

DISCUSSION

Study findings support the efficacy of Resourcefulness Training to significantly decrease perceived stress and improve psychological/physical outcomes with these vulnerable caregivers.

Adaptation of a psycho-educational group programme to improve coping in dementia caregiving: a feasibility study with mixed-methods

BACKGROUND

As the number of people living with dementia rapidly increases worldwide, the support provided by their informal caregivers remains key to the sustainability of most healthcare systems, this voluntary contribution representing 40% of the costs of dementia worldwide. Informal caregiving in dementia, however, is linked to long periods of chronic stress with frequent and serious negative consequences on the health and quality of life of the caregiver. A psycho-educational group intervention focusing on coping with the daily stress of dementia caregiving ("Learning to feel better… to help better"), developed in French-speaking Canada and showing broad effects on quality of life, was selected with the aim of 1) adapting it to a new cultural context (French-speaking Switzerland) based on identified facilitators and barriers, using a participative approach; and 2) conducting a feasibility study to evaluate whether the adapted programme showed similar or improved feasibility and effects compared to the original Canadian programme.

METHODS

A mixed-methods concurrent nested design was used to evaluate the feasibility and the effects on five quantitative core outcomes. Additional qualitative data helped document in depth the acceptability and impact of the intervention.

RESULTS

We shortened the programme from 30 to 21 h in total, which resulted in increased accessibility, in terms of facilitated recruitment of participants and inclusion of a broader range of informal caregivers. There were significant reductions in subjective burden (effect size: d = -0.32) and psychological distress (d = -0.48), as well as decreases in the stress reactions of informal caregivers related to the behaviour problems of the persons with dementia (d = -0.57). The qualitative results emphasized the usefulness of providing informal caregivers with structured procedures for efficiently tackling everyday challenges, and of enabling learning through a variety of channels and activities.

CONCLUSIONS

Substantial improvements are associated with this 21-h group intervention, organised in 7 sessions of 3 h each, focused on learning more efficient strategies to cope with the daily stress of dementia caregiving. This intervention empowered informal caregivers to master their daily challenges with more confidence, satisfaction and calm.

Telephone-Based Cognitive-Behavioral Therapy for Depression in Family Caregivers of Persons Living With Dementia: A Feasibility Study

The current study aimed to examine the usefulness of a telephone-based cognitive-behavioral therapy program for depression in 11 family caregivers of persons living with dementia. Data were collected and analyzed before (Session 1), after (Session 6), and at 3-month follow up using the Zarit Caregiver Burden Interview, General Self-Efficacy Scale, Rosenberg Self-Esteem Scale, and Self-Rating Depression Scale. Depression scores decreased significantly (p < 0.05) from Session 1 to Session 6. Results suggest that the program should address Proactivity of Action, a sub-item of self-efficacy, to reduce depression. In addition, the program enabled caregivers to reduce negative perceptions of their caregiving duty, which may lead to positive thinking and proactive behavior. Despite these findings, the program must be modified and research must continue, as this was a feasibility study with an intervention group only.

Caregiver Preparedness: A Therapeutic Mechanism and Moderating Factor on Outcomes for the Savvy Caregiver Program

OBJECTIVES

Evidence-based interventions for dementia caregivers, such as the Savvy Caregiver Program (SC), seek to address skills and knowledge deficits, caregiver burden, depressive symptoms, and grief. Little research has examined mechanisms by which these interventions accomplish their goals. Caregiver preparedness may be a possible mechanism by which caregiver interventions may confer benefits.

METHODS

The sample included 76 dementia caregivers who completed the 6-session SC. Participants completed the Anticipatory Grief Scale, Center for Epidemiological Studies-Depression Scale, the Preparedness for Caregiving Scale, and the Zarit Burden Interview-Short Form.

RESULTS

A repeated measures ANOVA was utilized to determine the interaction between baseline scores and pre-post change in caregiver preparedness. Analysis significantly predicted caregiver burden, (F(1) = 6.68, p=.012, partial η2=.10), depressive symptom endorsement, (F(1) = 6.41, p=.014, partial η2=.09, and anticipatory grief, (F(1) = 6.22, p=.02, partial η2=.1), post-treatment.

CONCLUSIONS

Pre-post change in caregiver preparedness significantly predicted pre-post change across measures of caregiver burden, depressive symptom endorsement, and anticipatory grief. Findings suggest that caregiver preparedness may be one mechanism by which the SC confers positive outcomes. These findings provide an empirical and theoretical basis for tailoring future dementia caregiver interventions.

CLINICAL IMPLICATIONS

Clinical Interventions may seek to improve caregiver preparedness and subsequent outcomes through utilization of programs like SC.

Optimizing outcomes, mechanisms, and recall of Cognitive Therapy for depression: Dose of constructive memory support strategies

OBJECTIVE

Poor memory for treatment is associated with worse patient outcomes. Therapist use of constructive memory support strategies, which help patients actively engage with treatment content, may improve patient memory for treatment. We sought to identify the dose of constructive memory support needed to optimize treatment outcomes, mechanisms, and patient recall.

METHOD

Adults with major depressive disorder (N = 178, mean age = 37.9, 63% female, 17% Hispanic or Latino/a) were randomized to Cognitive Therapy plus a Memory Support Intervention or Cognitive Therapy as usual. Because therapists from both groups used constructive memory support, treatment conditions were combined to maximize data. Depression and overall impairment were assessed before treatment, immediately post-treatment (POST), and six (6FU) and 12 months (12FU) after treatment. Patients completed measures of treatment mechanisms - utilization/competency in Cognitive Therapy skills - and treatment recall at POST, 6FU, and 12FU. Patient adherence to treatment was averaged across sessions.

RESULTS

Using Kaplan-Meier Survival Analyses, the optimal dose of constructive memory support was eight uses per session (sensitivity analysis range: 5-12 uses). Pre-treatment depression symptoms and patient perceptions of treatment may impact the optimal dose.

CONCLUSION

Eight uses of constructive memory support by therapists per session may optimize treatment outcomes, mechanisms, and recall over the long-term.

Changes in affective and cognitive distortion symptoms of depression are reciprocally related during cognitive behavior therapy

We tested the predictions from Beck's cognitive theory that change in cognitive distortions precedes and predicts change in affective symptoms of depression, and his secondary prediction that change in affective symptoms precedes and predicts change in cognitive distortions during the course of cognitive behavior therapy (CBT; Beck, 1963). We used bivariate latent difference score modeling to examine change in affective and cognitive distortion symptoms of depression over time in a sample of 1402 outpatients who received naturalistic CBT in a private practice setting. Patients completed the Beck Depression Inventory (BDI) at each therapy session to monitor their progress in treatment. We selected items from the BDI to create measures of affective and cognitive distortion symptoms that allowed us to assess change in those phenomena over the course of treatment. We examined BDI data from up to 12 sessions of treatment for each patient. As predicted by Beck's theory, we found that change in cognitive distortion symptoms preceded and predicted change in affective symptoms of depression, and that change in affective symptoms preceded and predicted change in cognitive distortion symptoms. Both effects were small in size. These findings support the notion that change in affective and cognitive distortion symptoms of depression each precedes and predicts the other - that is, they are reciprocal in nature during cognitive behavior therapy. We discuss implications of our findings for the nature of the change process in CBT.

Recruitment of family caregivers of persons with dementia: Lessons learned from a pilot randomized controlled trial

Family caregivers play an essential role in supporting the health and well-being of older adults with dementia, a population projected to increase rapidly over the coming decades. Enrolling caregivers of people with dementia (PWD) in research studies is vital to generating the evidence necessary to support broader implementation of efficacious intervention programs in real-world care delivery, but a range of challenges impede recruitment and enrollment of sufficiently large and representative sample sizes. In this article, we characterize the challenges and lessons learned from recruiting caregivers of PWD to participate in a pilot randomized control trial. We utilize Bronfenbrenner's ecological model to categorize the challenges into three levels: individual (i.e., understanding caregivers' time constraints and motivations), community (i.e., reaching underrepresented populations and accessing caregiver support groups) and institutional (i.e., obtaining informed consent and navigating research registries). We found that establishing rapport and maintaining flexibility with participants was crucial for motivating individuals to enroll in our study. Building trust with local communities by collaborating with support group leaders, appointing a co-investigator who is already embedded within a given community, and establishing equitable partnerships with organizations increased recruitment rates. At the institutional level, engaging experts in regulatory affairs and geriatrics may help overcome barriers in obtaining approval from institutional review boards. We also recommend using research registries of individuals who offer their contact information to researchers. The lessons learned from our research-including the challenges and potential solutions to overcome them-may promote more effective and efficient recruitment in future research.

Patient Responsiveness to a Sleep and Circadian Intervention in a Sample of Adults With Serious Mental Illness

Understanding patient responsiveness, a component of fidelity, is essential as it impacts treatment outcome and ongoing use of treatment elements. This study evaluated patient responsiveness-operationalized as receptivity to treatment modules and ratings of the usefulness and the utilization of treatment elements-to the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) in a sample of adults with serious mental illness (SMI) and sleep/circadian dysfunction. Adults with SMI and sleep/circadian dysfunction (N = 104) received TranS-C in a community mental health setting. Independent raters rated TranS-C sessions to assess receptivity. At posttreatment and 6-month follow-up, participants completed a usefulness scale, utilization scale, the PROMIS Sleep Disturbance (PROMIS-SD) and Sleep-Related Impairment (PROMIS-SRI) scales, DSM-5 Cross-Cutting Measure (DSM-5-CC), and Sheehan Disability Scale (SDS). Receptivity was rated as somewhat to fully understood, and predicted a reduction on the DSM-5-CC. On average, participants rated TranS-C as moderately useful and utilized treatment elements occasionally. Ratings of usefulness were associated with the PROMIS-SD, PROMIS-SRI, and DSM-5-CC at posttreatment, but not with the SDS. Ratings of utilization were not associated with outcome. The findings add to the literature on patient responsiveness, an implementation outcome, and provide data on the utility of TranS-C within a community mental health setting.

Serial Mediators of Memory Support Strategies Used With Cognitive Therapy for Depression: Improving Outcomes Through Patient Adherence and Treatment Skills

Patient memory for treatment is poor. Memory support strategies can be integrated within evidence-based psychological treatments to improve patient memory for treatment, and thereby enhance patient outcomes. The present study evaluated possible mechanisms of these memory support strategies. Specifically, we tested whether therapist use of memory support strategies indirectly predicts improved patient outcomes via serial improvements in (a) patient adherence throughout treatment and (b) patient utilization and competency of treatment skills. Adults with major depressive disorder (N = 178, mean age = 37.93, 63% female, 17% Hispanic or Latino) were randomized to Cognitive Therapy plus a Memory Support Intervention or Cognitive Therapy-as-usual. Because therapists from both treatment groups used memory support strategies, data from conditions were combined. Blind assessments of depression severity and overall impairment were conducted before treatment, immediately posttreatment (POST), at 6-month follow-up (6FU), and at 12-month follow-up (12FU). Patient adherence to treatment was rated by therapists and averaged across treatment sessions. Patients completed measures of treatment mechanisms-namely, utilization and competency in cognitive therapy skills-at POST, 6FU, and 12FU. Results of serial mediation models indicated that more therapist use of memory support predicted lower depression severity at POST, 6FU, and 12FU indirectly and sequentially through (a) increased patient adherence during treatment and (b) more utilization and competency of Cognitive Therapy skills at POST, 6FU, and 12FU. The same patterns were found for serial mediation models predicting lower overall impairment at POST, 6FU, and 12FU. Together, boosting memory for treatment may represent a promising means to enhance pantreatment mechanisms (i.e., adherence and treatment skills) as well as patient outcomes.

Non-Pharmacologic Interventions for Hispanic Caregivers of Persons with Dementia: Systematic Review and Meta-Analysis

Background: As the Hispanic/Latino (HL) population grows, so too does the need for HL family caregivers for persons with dementia. HL caregivers tend to have less education, lower health literacy, and lower income, each uniquely compounding burden. Research is needed to appropriately tailor interventions for this population. Objective: A systematic review and meta-analysis was conducted to 1) provide an updated review of non-pharmacologic intervention studies for HL dementia caregivers, 2) characterize promising interventions, and 3) highlight opportunities for future research. Methods: Databases were searched for articles evaluating non-pharmacologic interventions for HL dementia caregivers. Studies were excluded if target populations did not include HLs or if no intervention was delivered. Data were extracted and random effects meta-analysis was performed on two primary outcomes: caregiver depression and burden. Effect sizes were calculated as pre- and post-intervention standardized mean differences (SMD), and further depression subgroup meta-analysis was performed. Other secondary outcome measures (e.g., perceived social support, caregiver knowledge, anxiety) were evaluated qualitatively. Results: Twenty-three studies were identified. Most included multiple components pertaining to psychosocial support, caregiver education, and community resource facilitation. Many studies were successful in improving caregiver outcomes, though intervention design varied. Meta-analysis revealed minimal to moderate heterogeneity and small effect size in improving depressive symptoms (SMD = –0.31, 95% CI –0.46 to –0.16; I2 = 50.16%) and burden (SMD = –0.28, 95% CI –0.37 to –0.18; I2 = 11.06%). Conclusion: Although intervention components varied, many reported outcome improvements. Future studies may benefit from targeting physical health, addressing sociocultural and economic contexts of caregivers, and leveraging technology.

Outcomes From the Transdiagnostic Sleep and Circadian Intervention (TranS-C) for Midlife and Older Adults With Serious Mental Illness and Sleep and Circadian Dysfunction

The present study tested outcomes of the Transdiagnostic Sleep and Circadian Intervention (TranS-C) among midlife and older adults with serious mental illness (SMI). Further, we tested predictors-credibility, expectancy, usefulness, and utilization-that may affect TranS-C outcomes. Midlife and older participants from a community setting (>49 years, 62.3% female, 37.7% African American or Black) with sleep and circadian problems and SMI were randomized to receive TranS-C plus usual care (TranS-C+UC, n = 27) or usual care followed by delayed treatment with TranS-C (UC-DT, n = 26). Immediate and delayed TranS-C data were combined to increase power (combined n = 52). Outcomes were assessed at pretreatment, posttreatment, and 6-month follow-up. Credibility and expectancy were assessed during the second session. Usefulness and utilization of TranS-C skills were assessed at posttreatment and 6-month follow-up. TranS-C+UC, relative to UC-DT, was associated with improvements in depression symptoms, sleep disturbance, overall sleep health, and select sleep/wake outcomes, though not all improvements were sustained at 6-month follow-up. Lower usefulness of TranS-C skills predicted more severe sleep disturbance at posttreatment and daytime sleep-related impairment at posttreatment and 6-month follow-up. Lower utilization predicted more severe psychiatric symptoms at posttreatment, sleep disturbance at posttreatment and 6-month follow-up, and overall impairment and daytime sleep-related impairment at 6-month follow-up. Higher credibility and expectancy predicted greater usefulness of TranS-C skills at posttreatment and 6-month follow-up and greater utilization at 6-month follow-up. Together, findings highlight benefits of TranS-C for midlife and older adults with SMI. However, boosting credibility, expectancy, utilization, and usefulness may meaningfully improve TranS-C outcomes.

Which cognitive behavioral therapy delivery formats work for depressive symptoms in dementia caregivers? - A systematic review and network meta-analysis of randomized controlled trials

BACKGROUND

Cognitive behavioral therapy (CBT) has been shown to be effective to improve depressive symptoms by changing their cognitive processes and concepts for dementia caregivers (DCs). However, whether CBT can be effectively delivered in individual, group, telephone-administered, internet, combine formats remains unclear. We aimed to examine the most effective delivery format for CBT via a network meta-analysis (NMA).

METHODS

An exhaustive literature search was conducted based on Pubmed, Embase, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, the Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure database, Chinese Biomedical Literature Database, Wan Fang database, and unpublished data. RCTs were identified from their inception to January 15, 2022. We conducted pairwise and NMA to evaluate the relative effectiveness and rank probability (rank P-score) for different CBT delivery formats. A series of analyses and assessments, such as the risk of bias, and GRADE were performed concurrently. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were used for abstracting data.

RESULTS

A total of 37 studies were included in our analysis based on a series of rigorous screenings, which comprised 4191 DCs. Compared with controls, internet (SMD = -1.33, confidence interval (CI): -2.18, -0.66, GRADE low), telephone (SMD = -1.29, CI: -1.89, -0.61, GRADE moderate), and individual (SMD = -1.04, CI: -2.01, -0.07, GRADE very low) showed the largest improvement on depressive symptoms, whereas the group and combine delivery formats were not effective. Notably, there were no statistically significant differences between these five delivery formats: internet, telephone, individual, group, and combine. Sensitivity analyses supported the overall findings.

CONCLUSIONS

Our results suggested that internet, telephone, individual CBT delivery formats were effective for reducing depressive symptoms in DCs. Given the limitations of the NMA approach and the number of included studies, the result should be cautiously interpreted. Further RCTs with respect to the CBT based on different delivery formats' effectiveness are needed.

Psychotherapeutic Interventions for Dementia: a Systematic Review

Background and Objectives

While a range of psychotherapeutic interventions is available to support individuals with dementia, comprehensive reviews of interventions are limited, particularly with regard to outcomes related to adjustment and acceptance. The current review assesses studies that evaluated the impact of various forms of psychotherapeutic interventions on acceptance and adjustment to changing life circumstances for older adults with cognitive impairment.

Research Design and Methods

A systematic search of PubMed, PsycINFO, and CINAHL databases was conducted, restricted to articles published in English within the last 16 years (from 2003 to 2019). Twenty-four articles were identified that examined the effects of psychotherapeutic interventions on outcomes related to acceptance and adjustment which included internalizing symptoms, quality of life, self-esteem, and well-being. Fifteen studies examined interventions targeted towards individuals with cognitive impairment, while nine studies also targeted their caregivers.

Results

Interventions that impacted outcomes related to acceptance and adjustment (e.g., adaptation, depressive symptoms, helplessness, self-esteem, and quality of life) varied in their theoretical approach, which incorporated elements of cognitive behavioural therapy (CBT), problem-solving therapy, psychotherapy, reminiscence therapy, interpersonal therapy, mindfulness-based therapy, and meaning-based, compassion-focused therapy. Among all interventions, reductions in depression were the most commonly reported treatment outcome particularly among interventions that incorporated problem-focused and meaning-based therapies. Mixed findings were reported with regard to outcomes related to helplessness, quality of life, self-esteem, and life satisfaction indices for individuals with cognitive impairment.

Discussion and Implications

There is some support for the effectiveness of psychotherapeutic interventions on improving acceptance and adjustment in older adults with cognitive impairment, particularly with regard to reducing depressive symptoms.

Systematic Review and Meta-Analysis of Racial and Ethnic Differences in Dementia Caregivers' Well-Being

BACKGROUND AND OBJECTIVES

Studies comparing racial/ethnic differences on measures of psychological and physical well-being for dementia caregivers have reported differences between minority and white caregivers. Recruitment methods often differ for minority and white participants due to enrollment targets and may lead to biased comparisons, especially in convenience samples. We aimed to examine racial/ethnic differences in dementia caregiver outcomes and to determine whether differences vary between studies with population-based or convenience samples.

RESEARCH DESIGN AND METHODS

We systematically reviewed articles with primary data from PubMed, Google Scholar, and PsycINFO. We included studies comparing African American or Hispanic/Latino to white dementia caregivers on measures of psychological well-being or physical well-being. Reviewers screened titles and abstracts, reviewed full texts and conducted risk-of-bias assessments. Meta-analyses were conducted to assess effects by race/ethnicity and study bias.

RESULTS

A total of 159 effects were extracted from 38 studies, 2 of which were population based. Random-effects models revealed small but statistically significant effects with better psychological well-being in African American caregivers compared with white caregivers in both population-based (d = -0.22) and convenience sample studies (d = -0.21). Hispanics/Latino caregivers reported lower levels of physical well-being than white caregivers (d = 0.12), though these effects varied by level of rated study bias.

DISCUSSION AND IMPLICATIONS

Consistency across study methods raises confidence in the validity of previous reports of better psychological well-being in African American caregivers. Future studies should use population-based samples with subgroups of Hispanic/Latino, Asian American, and American Indian caregivers that are culturally distinct on factors such as country of origin and tribe.

Effects of Psychosocial Interventions and Caregiving Stress on Cardiovascular Biomarkers in Family Dementia Caregivers: The UCSD Pleasant Events Program (PEP) Randomized Controlled Trial

BACKGROUND

This study examined whether biological mechanisms linking dementia caregiving with an increased risk of coronary heart disease can be modified by psychosocial interventions and which caregivers might benefit the most from an intervention.

METHODS

Spousal dementia caregivers were randomized to 12-week treatment with either a behavioral activation intervention (ie, Pleasant Events Program [PEP]; n = 60), or an active control Information and Support (IS; n = 63) condition. Indicators of caregiving stress were assessed pretreatment and circulating cardiovascular biomarkers were measured pre- and posttreatment.

RESULTS

There were no significant changes in biomarker levels from pre- to posttreatment both by treatment condition and across all caregivers. Regardless of the treatment condition, exploratory regression analysis revealed that caregivers were more likely to show significant decreases in C-reactive protein (CRP) and D-dimer when their spouse had severe functional impairment; in interleukin (IL)-6 and CRP when they had greater distress due to care recipient's problem behaviors; in tumor necrosis factor (TNF)-α when they had higher levels of negative affect; and in IL-6, CRP, TNF-α, and D-dimer when they had higher personal mastery. Within the PEP group, caregivers with higher negative affect and those with higher positive affect were more likely to show a reduction in von Willebrand factor and D-dimer, respectively. Within the IS group, caregivers whose spouse had severe functional impairment were more likely to show a decrease in IL-6.

CONCLUSIONS

Unlike the average caregiver, caregivers high in burden/distress and resources might benefit from psychosocial interventions to improve cardiovascular risk, although these observations need confirmation.

Remotely delivered information, training and support for informal caregivers of people with dementia

BACKGROUND

Many people with dementia are cared for at home by unpaid informal caregivers, usually family members. Caregivers may experience a range of physical, emotional, financial and social harms, which are often described collectively as caregiver burden. The degree of burden experienced is associated with characteristics of the caregiver, such as gender, and characteristics of the person with dementia, such as dementia stage, and the presence of behavioural problems or neuropsychiatric disturbances. It is a strong predictor of admission to residential care for people with dementia. Psychoeducational interventions might prevent or reduce caregiver burden. Overall, they are intended to improve caregivers' knowledge about the disease and its care; to increase caregivers' sense of competence and their ability to cope with difficult situations; to relieve feelings of isolation and allow caregivers to attend to their own emotional and physical needs. These interventions are heterogeneous, varying in their theoretical framework, components, and delivery formats. Interventions that are delivered remotely, using printed materials, telephone or video technologies, may be particularly suitable for caregivers who have difficulty accessing face-to-face services because of their own health problems, poor access to transport, or absence of substitute care. During the COVID-19 pandemic, containment measures in many countries required people to be isolated in their homes, including people with dementia and their family carers. In such circumstances, there is no alternative to remote delivery of interventions.

OBJECTIVES

To assess the efficacy and acceptability of remotely delivered interventions aiming to reduce burden and improve mood and quality of life of informal caregivers of people with dementia.

SEARCH METHODS

We searched the Specialised Register of the Cochrane Dementia and Cognitive Improvement Group, MEDLINE, Embase and four other databases, as well as two international trials registries, on 10 April 2020. We also examined the bibliographies of relevant review papers and published trials.

SELECTION CRITERIA

We included only randomised controlled trials that assessed the remote delivery of structured interventions for informal caregivers who were providing care for people with dementia living at home. Caregivers had to be unpaid adults (relatives or members of the person's community). The interventions could be delivered using printed materials, the telephone, the Internet or a mixture of these, but could not involve any face-to-face contact with professionals. We categorised intervention components as information, training or support. Information interventions included two key elements: (i) they provided standardised information, and (ii) the caregiver played a passive role. Support interventions promoted interaction with other people (professionals or peers). Training interventions trained caregivers in practical skills to manage care. We excluded interventions that were primarily individual psychotherapy. Our primary outcomes were caregiver burden, mood, health-related quality of life and dropout for any reason. Secondary outcomes were caregiver knowledge and skills, use of health and social care resources, admission of the person with dementia to institutional care, and quality of life of the person with dementia.

DATA COLLECTION AND ANALYSIS

Study selection, data extraction and assessment of the risk of bias in included studies were done independently by two review authors. We used the Template for Intervention Description and Replication (TIDieR) to describe the interventions. We conducted meta-analyses using a random-effects model to derive estimates of effect size. We used GRADE methods to describe our degree of certainty about effect estimates.

MAIN RESULTS

We included 26 studies in this review (2367 participants). We compared (1) interventions involving training, support or both, with or without information (experimental interventions) with usual treatment, waiting list or attention control (12 studies, 944 participants); and (2) the same experimental interventions with provision of information alone (14 studies, 1423 participants). We downgraded evidence for study limitations and, for some outcomes, for inconsistency between studies. There was a frequent risk of bias from self-rating of subjective outcomes by participants who were not blind to the intervention. Randomisation methods were not always well-reported and there was potential for attrition bias in some studies. Therefore, all evidence was of moderate or low certainty. In the comparison of experimental interventions with usual treatment, waiting list or attention control, we found that the experimental interventions probably have little or no effect on caregiver burden (nine studies, 597 participants; standardised mean difference (SMD) -0.06, 95% confidence interval (CI) -0.35 to 0.23); depressive symptoms (eight studies, 638 participants; SMD -0.05, 95% CI -0.22 to 0.12); or health-related quality of life (two studies, 311 participants; SMD 0.10, 95% CI -0.13 to 0.32). The experimental interventions probably result in little or no difference in dropout for any reason (eight studies, 661 participants; risk ratio (RR) 1.15, 95% CI 0.87 to 1.53). In the comparison of experimental interventions with a control condition of information alone, we found that experimental interventions may result in a slight reduction in caregiver burden (nine studies, 650 participants; SMD -0.24, 95% CI -0.51 to 0.04); probably result in a slight improvement in depressive symptoms (11 studies, 1100 participants; SMD -0.25, 95% CI -0.43 to -0.06); may result in little or no difference in caregiver health-related quality of life (two studies, 257 participants; SMD -0.03, 95% CI -0.28 to 0.21); and probably result in an increase in dropouts for any reason (12 studies, 1266 participants; RR 1.51, 95% CI 1.04 to 2.20).

AUTHORS' CONCLUSIONS

Remotely delivered interventions including support, training or both, with or without information, may slightly reduce caregiver burden and improve caregiver depressive symptoms when compared with provision of information alone, but not when compared with usual treatment, waiting list or attention control. They seem to make little or no difference to health-related quality of life. Caregivers receiving training or support were more likely than those receiving information alone to drop out of the studies, which might limit applicability. The efficacy of these interventions may depend on the nature and availability of usual services in the study settings.

Cultural adaptations of cognitive behavioural therapy for Latin American patients: unexpected findings from a systematic review

The current literature extensively recommends making cultural adaptations to psychological therapies, in order to address the differences in values, beliefs and attitudes that patients from different ethnic groups might hold. Although this approach has shown positive outcomes in some settings, it is not well established yet whether such adaptations are needed for all therapies and in all cultures. Therefore, the main aim of this study was to systematically review the literature regarding culturally adapted and ‘conventional’ cognitive behavioural therapy (CBT) for Latin American patients, within Latin American and non-Latin American countries. Sixty empirical studies regarding the effectiveness of culturally adapted and conventional CBT were included in this review. The included studies were carried out in Latin American and non-Latin American countries. The information from all studies was synthesized and assessed, including intervention effect sizes, patient retention rates, methodological quality of the papers, and the type of cultural adaptation made to the therapy. There were no differences between the sets of studies in terms of effectiveness, retention rates, methodological quality, or proportion of statistically significant interventions. Most of the cultural adaptations were peripheral or unspecified. The evidence to date indicates that both conventional and culturally adapted CBT offer the same benefits for Latin American patients in terms of effectiveness and retention rates. Rather than focusing on cultural adaptations, clinicians are encouraged to improve the way they deliver CBT through training and supervision.

Key learning aims

An exploration of the relationships between patient application of CBT skills and therapeutic outcomes during a two-week CBT treatment

The application of Cognitive Behavioural Therapy (CBT) skills are believed to be a mechanism of therapeutic change in treatment. Research has shown that the application of CBT skills affects outcomes, however, the way these relationships may change during treatment has not been explored. In this study, a naturalistic observational approach is used to examine the relationships between patients' wellbeing, symptoms, and the application of CBT skills throughout treatment. It is hypothesized that the application of CBT skills would lead to an increase in patients reported wellbeing, and a decrease in symptoms. Additionally, it was hypothesized that the application of CBT skills affects wellbeing and symptoms at different points in therapy. A sample of 584 patients in a two-week CBT treatment completed session-to-session measures of wellbeing, symptoms, and their application of CBT skills. Results of an autoregressive cross-lagged path analysis indicated that in the early stages of treatment the application of CBT skills predicted patient wellbeing but not symptoms. At the later stages of therapy, the application of CBT skills predicted both patient wellbeing and symptoms. At no point in treatment did patient wellbeing or symptoms predict the later application of CBT skills. Implications and future directions for research are discussed.

Efficacy of cognitive-behavioural therapy interventions on reducing burden for caregivers of older adults with a neurocognitive disorder: a systematic review and meta-analysis

By 2025, 34 million people worldwide will be living with Alzheimer's disease or another form of dementia (i.e., neurocognitive disorders). Symptoms of neurocognitive disorders have functional repercussions on daily activities. People with neurocognitive disorders often rely on a caregiver to alleviate the impact of their symptoms, but this help has consequences for the caregiver. Indeed, caregivers report subjective burden, depressive symptoms, stress, anxiety and a lower quality of life than non-caregivers. Multiple cognitive-behavioral therapy (CBT) trials have been conducted to reduce these symptoms for caregivers. No meta-analysis has been conducted to evaluate the efficacy of this type of intervention on reducing subjective burden. Articles were selected from PsycNet, MEDLINE, AgeLine and ProQuest Dissertation and Theses for the period from 2000 to 2017. Article selection, data extraction and bias analysis for individual studies were completed by two independent authors who used a consensus procedure when discrepancies occurred. A total of 20 articles were included in the systematic review. Ten studies evaluated the efficacy of CBT in reducing subjective burden, and the meta-analysis suggested a significant reduction in subjective burden following CBT. Additionally, 17 studies evaluated the efficacy in reducing depressive symptoms, and the meta-analysis revealed a significant reduction for these caregivers following CBT. CBT for caregivers of individuals with a neurocognitive disorder had no impact on stress, anxiety, or quality of life.

Randomized Controlled Trial of the Caregiver Orientation for Mobilizing Personal Assets and Strengths for Self-Care (COMPASS) for Caregiving Journey: A National Family Caregiver Support Program in a Long-Term Care Insurance System

OBJECTIVES

To investigate the effects of a national support program on family caregivers for long-term care (LTC) recipients.

DESIGN

A single-blinded randomized controlled trial compared the 8-week Caregiver Orientation for Mobilizing Personal Assets and Strengths for Self-Care (COMPASS) program consisting of 6 individual in-home, 3 group support, and 2 telephone sessions with a multicomponent intervention, and a control group.

SETTING AND PARTICIPANTS

In total, 969 caregivers who were living with LTC recipients assessed as having a high caregiving burden in 12 Korean cities.

MEASURES

The primary outcomes were depression, burden, and stress levels of caregivers, the secondary outcomes were caregiver self-efficacy, positive aspects of caregiving, social support, social activities, and health risk behaviors. These outcomes were measured at baseline and after the 8-week program, analyzed using modified intention-to-treat, per-protocol (PP), and non-PP analyses.

RESULTS

The modified intention-to-treat analysis revealed significant improvements in burden (effect size, = 0.010, P = .008), depression (η_p² = 0.012, P = .003), and health risk behaviors (η_p² = 0.010, P = .012) for the experimental group compared with the control group. However, there were no significant differences between the 2 groups in improving stress (P = .997), social support (P = .234), or social activities (P = .816). The PP analysis indicated that the COMPASS program was successful in increasing positive aspects of caregiving (η_p² = 0.013, P = .004) and self-efficacy (η_p² = 0.010, P = .032) compared with the control group.

CONCLUSIONS AND IMPLICATIONS

The COMPASS program was effective in family caregivers of LTC recipients in critical aspects of physical and psychological outcomes, especially in demonstrating the important role of participating in group support sessions. It is feasible for the program to become a formal national support program as part of the national insurance system in Republic of Korea.

The Effect of a Nurse-Led Cognitive Behavioral Protocol on Depressive Symptoms and Coping Strategies of Dementia Caregivers

BACKGROUND

Family caregivers of patients with dementia (PWD) often experience depressive symptoms and use poor coping strategies. Cognitive behavioral interventions may enhance positive appraisals of caregiving-related issues and the utilization of active coping strategies among caregivers, which may help prevent caregiver depression. However, there is a shortage of primary, community-based mental health services in China, and little research has been conducted on the effect of nurse-led mental health programs in this population.

PURPOSE

This study explored the effect of a nurse-led cognitive behavioral intervention on depressive symptoms and coping strategies among family caregivers of PWD in China.

METHODS

This randomized controlled trial used data from a sample of 112 caregivers screened from 276 potential participants in a city in southeastern China. The sample was randomly assigned to an intervention group (n = 56) and a control group (n = 56). The intervention group received five monthly in-home, nurse-led cognitive behavioral sessions and telephone consultations after each session. The control group received five monthly, short, general conversations with nurse interventionists at the participants' homes, in the hospital, or via telephone. Depressive symptoms, coping strategies, and the demographics of caregiving dyads were collected at Time 1 (baseline), Time 2 (the end of the 5-month intervention), and Time 3 (2-month follow-up). IBM SPSS Statistics Version 19.0 was used for data analysis.

RESULTS

Eighty-two participants (intervention group: n = 47, control group: n = 35) completed the three evaluations. No significant group differences were found in baseline characteristics between the two groups. The general linear model repeated-measures analysis of variance indicated a significant difference in depressive symptoms and active coping between groups over time, with p < .001 for the interaction between depressive symptoms and groups and p < .01 for the interaction between active coping and groups. A similar result did not occur for passive coping. The t tests further supported a significant interventional effect on participants' depressive symptoms and active coping.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

This nurse-led cognitive behavioral intervention was effective in decreasing depressive symptoms and improving active coping among study participants. The findings suggest the improvement of mental health services and social policies in China to support family caregivers of PWD.

Screening for Cognitive Impairment in Older Adults: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

IMPORTANCE

Early identification of cognitive impairment may improve patient and caregiver health outcomes.

OBJECTIVE

To systematically review the test accuracy of cognitive screening instruments and benefits and harms of interventions to treat cognitive impairment in older adults (≥65 years) to inform the US Preventive Services Task Force.

DATA SOURCES

MEDLINE, PubMed, PsycINFO, and Cochrane Central Register of Controlled Trials through January 2019, with literature surveillance through November 22, 2019.

STUDY SELECTION

Fair- to good-quality English-language studies of cognitive impairment screening instruments, and pharmacologic and nonpharmacologic treatments aimed at persons with mild cognitive impairment (MCI), mild to moderate dementia, or their caregivers.

DATA EXTRACTION AND SYNTHESIS

Independent critical appraisal and data abstraction; random-effects meta-analyses and qualitative synthesis.

MAIN OUTCOMES AND MEASURES

Sensitivity, specificity; patient, caregiver, and clinician decision-making; patient function, quality of life, and neuropsychiatric symptoms; caregiver burden and well-being.

RESULTS

The review included 287 studies with more than 280 000 older adults. One randomized clinical trial (RCT) (n = 4005) examined the direct effect of screening for cognitive impairment on patient outcomes, including potential harms, finding no significant differences in health-related quality of life at 12 months (effect size, 0.009 [95% CI, -0.063 to 0.080]). Fifty-nine studies (n = 38 531) addressed the accuracy of 49 screening instruments to detect cognitive impairment. The Mini-Mental State Examination was the most-studied instrument, with a pooled sensitivity of 0.89 (95% CI, 0.85 to 0.92) and specificity of 0.89 (95% CI, 0.85 to 0.93) to detect dementia using a cutoff of 23 or less or 24 or less (15 studies, n = 12 796). Two hundred twenty-four RCTs and 3 observational studies including more than 240 000 patients or caregivers addressed the treatment of MCI or mild to moderate dementia. None of the treatment trials were linked with a screening program; in all cases, participants were persons with known cognitive impairment. Medications approved to treat Alzheimer disease (donepezil, galantamine, rivastigmine, and memantine) improved scores on the ADAS-Cog 11 by 1 to 2.5 points over 3 months to 3 years. Psychoeducation interventions for caregivers resulted in a small benefit for caregiver burden (standardized mean difference, -0.24 [95% CI, -0.36 to -0.13) over 3 to 12 months. Intervention benefits were small and of uncertain clinical importance.

CONCLUSIONS AND RELEVANCE

Screening instruments can adequately detect cognitive impairment. There is no empirical evidence, however, that screening for cognitive impairment improves patient or caregiver outcomes or causes harm. It remains unclear whether interventions for patients or caregivers provide clinically important benefits for older adults with earlier detected cognitive impairment or their caregivers.

Usefulness and utilization of treatment elements from the Transdiagnostic Sleep and Circadian Intervention for adolescents with an evening circadian preference

OBJECTIVE

Existing research has demonstrated that patient ratings of usefulness and ratings of utilization of treatment elements are associated with treatment outcome. Few studies have examined this relationship among adolescents and with an extended follow-up. This study examined the extent to which elements of the Transdiagnostic Sleep and Circadian Intervention (TranS-C) were rated by youth as useful and utilized 6-months and 12-months after treatment.

METHOD

Participants were 64 adolescents with an evening circadian preference who were given TranS-C as a part of their participation in a NICHD-funded study. At 6-month and 12-month follow-up, they completed the Usefulness Scale, the Utilization Scale, a 7-day sleep diary assessing total sleep time (TST) and bedtime, and the Children's Morningness-Eveningness Preference Scale (CMEP).

RESULTS

On average, adolescents rated treatment elements as moderately useful and they utilized the treatment elements occasionally. Ratings of usefulness were associated with TST at 6-month follow-up, but not with bedtime or CMEP. Ratings of utilization were associated with a change in bedtime from 6-month to 12-month follow-up, but not with TST or CMEP. Ratings of usefulness and utilization were associated with selected treatment outcome measures at both follow-ups.

CONCLUSIONS

These findings have implications for understanding mechanisms of change following treatment.

Telephone-based behavioral activation intervention for dementia family caregivers: Outcomes and mediation effect of a randomized controlled trial

OBJECTIVES

The study examined the effects of a telephone-administered psycho-education with behavioral activation intervention (TBA) for family caregivers of person's with Alzheimer's dementia to reduce levels of depressive symptoms and burden and to enhance relationship satisfaction with the care-recipient METHODS: A double-blinded randomized trial compared TBA with telephone-based psycho-education with general monitoring (TGM). Ninety-six dementia caregivers were randomized. Both conditions received four weekly psycho-education sessions led by a social worker. TBA participants then received eight bi-weekly behavioral activation practice sessions delivered by paraprofessionals. TGM participants received eight bi-weekly monitoring sessions by paraprofessionals.

RESULTS

As compared to TGM, TBA participants reported significantly larger reductions in depressive symptoms and burden and larger improvement in relationship satisfaction. Self-efficacy for controlling upsetting thoughts was found to have a partial meditation effect between TBA and the reduction of depressive symptoms. Qualitative feedback suggested that TBA participants expressed unique gains in awareness and developing new ways of reappraising the caregiving situation.

CONCLUSION

TBA was an effective intervention to reduce depressive symptoms and burden as well as to enhance relationship satisfaction in dementia caregivers.

PRACTICE IMPLICATIONS

The use of telephone and trained paraprofessionals can enhance the accessibility and sustainability of behavioral activation intervention for dementia family caregivers.

Managing behavioural and psychological symptoms in community dwelling older people with dementia: 1. A systematic review of the effectiveness of interventions

Background

Two-thirds of people living with dementia live at home in the UK and many experience distressing behavioural and psychological symptoms. This systematic review evaluates the effectiveness of non-pharmacological interventions for behavioural and psychological symptoms among community-dwelling people living with dementia.

Methods

This two-stage review undertook an initial mapping of the literature followed by a systematic review of relevant randomised controlled trials. We searched electronic databases for pertinent studies reporting outcomes from interventions from January 2000 to March 2015 and updated searches in October 2016. We included studies that considered behavioural and psychological symptom management for older people living with dementia who live at home and excluded studies conducted in long-term care settings. This paper presents findings from a narrative synthesis of 48 randomised controlled trials evaluating interventions for people living with dementia alone, family carers alone and patient-carer dyads.

Results

We retrieved 17,871 de-duplicated records and screened them for potential inclusion. Evidence from 48 randomised controlled trials suggests that family carer training and educational programmes that target problem behaviours and potential triggers can improve outcomes. Nurses and occupational therapists appear to help people with dementia with behavioural and psychological symptoms, but professional comparisons are lacking and there is no shared language about or understanding of behavioural and psychological symptoms amongst professionals, or between professionals and family carers.

Conclusions

Future research should focus on the effectiveness of components of multi-faceted programmes and their cost effectiveness and include qualitative data to better target interventions for behavioural and psychological symptoms. It is important to consider family carer readiness to use non-pharmacological strategies and to develop a shared language about the inherent needs and communications of behavioural and psychological symptoms.

Photojournalism-Based Intervention Reduces Caregiver Burden and Depression in Alzheimer's Disease Family Caregivers

Purpose: Art interventions have demonstrated holistic benefits for persons living with dementia and their caregivers. In this article, we describe the results of a pilot photojournalism program for 10 unpaid caregivers of persons living with dementia, with respect to caregivers' experience in the program and their psychological well-being. Design: Caregivers participated in four sessions led by a professional photojournalist who taught principles of photography. Between the sessions, caregivers took photographs that represented what caregiving meant to them using digital cameras provided in the program. During the sessions, instruction was interspersed with discussion of caregivers' photographs. Method: Caregiver burden and depressive symptoms were measured pre- and postprogram. Qualitative exploration included sessions' observations, viewing caregivers' photographs, and recording caregivers' accompanying comments. Findings: For participants with pre- and postprogram data, caregiver burden decreased significantly (p = .037). For caregivers with pre- and postprogram data, depressive symptoms decreased nonsignificantly (p = .066). Clinically meaningful reductions in caregiver burden and depressive symptoms were attained. Qualitative findings highlighted caregivers' strong engagement with the project, the facilitator, and other participants, and reflection on multiple aspects of their experience. Conclusions: This intervention helped caregivers creatively communicate their experience and demonstrated efficacy in the improvement of caregivers' psychological well-being.

The Role of Mutuality and Coping in a Nurse-Led Cognitive Behavioral Intervention on Depressive Symptoms Among Dementia Caregivers

The current study explored whether mutuality and coping predicted and/or mediated the effect of a nurse-led cognitive behavioral intervention (NLCBI) on depressive symptoms of caregivers of persons with dementia. The intervention group (n = 56) received five monthly in-home nurse-led cognitive behavioral sessions and consultation calls after each session. The control group (n = 56) received five monthly short general conversations with the nurse interventionist. Questionnaires on study variables and demographics were collected at baseline, end of intervention, and 2-month follow up. Improved mutuality (β = -0.75, p = 0.049) and active coping (β = -2.06, p = 0.0001) and decreased passive coping (β = 1.43, p = 0.001) were found to predict the reduction of depressive symptoms among caregivers in the NLCBI. However, none of these variables mediated the interventional effect. Regular mental health nursing interventions are suggested to focus on enhancing mutuality and active coping and decreasing passive coping to maintain caregivers' mental health.

TARGETS

Caregivers of persons with dementia.

INTERVENTION DESCRIPTION

Nurse-led cognitive behavioral sessions and subsequent consultation calls.

MECHANISMS OF ACTION

Impacted caregivers' reappraisals, thus improving their active coping skills and mutuality and decreasing their passive coping, which directly reduced their depressive symptoms.

OUTCOMES

Mutuality, active coping, and passive coping played a predicting, but not mediating, role in the effect of the NLCBI. [Res Gerontol Nurs. 2019; 12(1):44-55.].

The assessment of cognitive-behavioral therapy skills in patients diagnosed with health anxiety: Development and pilot study on an observer-based rating scale

Cognitive-behavioral therapy is a highly effective treatment of health anxiety, but it remains unclear through which mechanisms treatment effects prevail. Some evidence suggests that patients acquire skills-understood as techniques helping them reach therapy goals-through psychotherapy. In the current study, an observer-based rating scale for the skills assessment of patients with health anxiety (SAPH) was developed and validated in a pilot study. Based on 177 videotapes, four independent raters evaluated the frequency of skills acquired during cognitive and exposure therapy among 66 patients diagnosed with health anxiety with the SAPH. Predictive validity was evaluated by the Yale-Brown Obsessive-Compulsive Scale for Hypochondriasis. The SAPH demonstrated good interrater reliability (ICC_(1,2)  = .88, p < .001, 95% CI [.81, .92]) and internal consistency (α = .94). Although patient skills did not significantly increase during three sessions, they significantly predicted a reduction in health anxiety symptoms at the end of treatment (R²  = .35). Patients' skills are highly important within the treatment of health anxiety. By providing external ratings of patients' skills with good psychometric properties, our pilot data suggest that the SAPH may complement current tools for the assessment of skills, specifically in targeting health anxiety.

Depression in carers of people with dementia from a minority ethnic background: Systematic review and meta-analysis of randomised controlled trials of psychosocial interventions

OBJECTIVES

Systematic review and meta-analysis to determine the effectiveness of interventions in reducing depressive symptoms in ethnic minority carers of people with dementia.

METHODS

We systematically searched EMBASE, CINAHL, MEDLINE, PsycINFO, PsycARTICLES, Applied Social Sciences Index and Abstracts (ASSIA), The Cochrane Central Register of Controlled Trials (CENTRAL), and Sociological Abstracts and Social Policy and Practices databases from 1990 to 2015, supplemented by a grey literature search, hand searches of bibliographies, and contacting authors. Study quality was assessed independently by two researchers using The Effective Public Health Practice Project Quality Assessment Tool, with an inter-rater reliability of Cohen's kappa of 0.72 (95% CI, 0.42-1.01). Narrative synthesis and meta-analysis were used to assess intervention effectiveness. Meta-regression was used to assess whether factors such as intervention type, peer support, and ethnicity accounted for hetereogeneity.

RESULTS

Thirteen studies were eligible for inclusion, with 1076 participants in control groups and 980 participants in intervention groups; 12 studies provided estimates for meta-analysis. All studies were from the United States. Interventions were associated with an overall mean reduction in depression in caregivers (SMD -0.17 (95% CI, -0.29 to -0.05; P = 0.005). Meta-regression did not indicate any potential sources of heterogeneity, although narrative synthesis suggested that interventions developed with the target ethnic minority group's preferred mode of engagement in mind alongside cultural adaptations may have enhanced effectiveness.

CONCLUSIONS

Psychosocial interventions for depression in ethnic minority carers of people with dementia are effective and could be enhanced through cultural adaptations. High-quality studies targeting minority ethnic groups outside of the United States are needed.

Do interventions that include education on dementia progression improve knowledge, mental health and burden of family carers? A systematic review

BACKGROUND AND AIM

The European Association of Palliative Care recommends that family carers need education on the progression of dementia. This systematic review aimed to explore whether interventions incorporating education regarding the progressive nature of dementia increased carers' understanding of dementia and improved mental health and burden.

METHOD

MEDLINE, PsycINFO and CINAHL were searched to April 2018. Randomised controlled trials with samples of family carers of someone with dementia were eligible. Included interventions involved a component aimed to increase the carer's understanding of the progression of dementia. Outcomes of interest included: knowledge of dementia, depression, burden and pre-death grief.

RESULTS

Searches identified 3221 unique citations of which 11 studies were eligible for review. Interventions ranged from 4 to 16 sessions of which 1 to 3 sessions focused on the progression of dementia. Knowledge: Two studies evaluated carers' knowledge of dementia. One found no difference between the trial arms immediately after the intervention or three months later. The second found a significant intervention effect at the end of the intervention but not at three-month follow-up. Depression: Seven studies evaluated intervention effects on depression. Meta-analysis of three trials showed significant differences in mean follow-up scores favouring intervention over control. The remaining four studies did not show differences in depression between intervention and control groups. Burden: Nine studies evaluated burden and were examined in two meta-analyses (mean scores at follow-up and mean change scores from baseline to follow-up), neither of which found a benefit for intervention over control. Using the grading of recommendations assessment, development and evaluation system, we judged the quality of evidence to be very low for depression and low for burden, knowledge and pre-death grief, reducing our confidence in any of the effect estimates.

CONCLUSION

The evidence was not sufficient to support or refute the effectiveness of education on progression of dementia on carers' knowledge and mental health.

Psychological Interventions for Dementia Caregivers: What We Have Achieved, What We Have Learned

With the rising dementia population, more and more programs have been developed to help caregivers deal with the care-recipient as well as their own frustrations. Many interventions aim to enhance caregiver's ability to manage behavior problems and other deteriorations in functioning, with less direct emphasis placed on caring for the caregivers. We argue that techniques based on psychotherapy are strategically important in assistance provided to caregivers because of their utility for promoting emotional health. This article provides a focused review of such methods used in evidence-based intervention programs, along with the mechanisms of change associated with these methods. While cognitive-behavioral therapy (CBT) has a strong evidence base, there is also a growing trend to package CBT techniques into various psychoeducational programs. These programs, which we call psychoeducation with psychotherapeutic programs, have been consistently found to be effective in reducing caregiver distress and are suited for delivery in group format, even by paraprofessionals, to lower the cost of intervention. A recent trend is the effective use of technological aids (e.g., the internet) to deliver CBT and psychoeducation, reaching more caregivers. As for therapeutic mechanisms, the use of coping skills, reduced dysfunctional thoughts, and increased self-efficacy in controlling upsetting thoughts has received support in studies. We conclude that psychotherapeutic techniques are increasingly being used effectively and efficiently to assist caregivers, aided by successful adaptation for educational or technologically advanced means of delivery. More research on therapeutic mechanisms is needed to understand how the techniques work and how they can be further refined.

Which interventions work for dementia family carers?: an updated systematic review of randomized controlled trials of carer interventions

ABSTRACTObjective:The aim of this study was to update the literature on interventions for carers of people with dementia published between 2006 and 2016 and evaluate the efficacy of psychoeducational programs and psychotherapeutic interventions on key mental health outcomes (depression, anxiety, burden, and quality of life).

METHODS

A meta-analysis was carried out of randomized controlled trials of carer interventions using MEDLINE, PsycINFO, Scopus, and Cochrane Central Register of Controlled Trials.

RESULTS

The majority of studies were conducted in Western and Southern Europe or the United States and recruited carers of people with Alzheimer's disease or dementia grouped as a whole. The most commonly used outcome measures were depression and burden across studies. The updated evidence suggested that psychoeducation-skill building interventions delivered face-to-face can better impact on burden. Psychotherapeutic interventions underpinned by Cognitive Behavior Therapy (CBT) models demonstrated strong empirical support for treating anxiety and depression and these effects were not affected by the mode of delivery (i.e. face-to-face vs. technology). A modern CBT approach, Acceptance and Commitment Therapy (ACT), seemed to be particularly beneficial for carers experiencing high levels of anxiety.

CONCLUSIONS

Future research needs to explore the efficacy of interventions on multiple clinical outcomes and which combination of interventions (components) would have the most significant effects when using CBT. The generalization of treatment effects in different countries and carers of different types of dementia also need to be addressed. More research is needed to test the efficacy of modern forms of CBT, such as ACT.

Reappraising the Efficacy and Acceptability of Multicomponent Interventions for Caregiver Depression in Dementia: The Utility of Network Meta-Analysis

Background

Previous meta-analyses have demonstrated the efficacy of interventions for caregiver depression in dementia. However, they generally lumped the interventions together without accounting for the multicomponent nature of most interventions. It is unknown which combination of components contributed to the efficacy and should be implemented in clinical practice.

Objectives

To reappraise the interventions for caregiver depression from a recent systematic review, and evaluate whether a network meta-analytic approach offers additional insight into the efficacy and acceptability of multicomponent interventions.

Research Design and Methods

This study built upon a recent systematic review which identified 33 RCTs on caregiver depression from multiple databases (Medline, EMBASE, CENTRAL, PsycINFO, PSYNDEX). The 33 RCTs had different combinations of components serving at least one of the three key functions: addressing the care needs of persons with dementia (“CN”), addressing caregiving competency (“CC”), and providing emotional support for loss and grief (“ES”). A Bayesian network meta-analysis was conducted to compare the efficacy and all-cause attrition across different combinations of interventions.

Results

CN–CC combination was significantly more efficacious than treatment-as-usual (standardized mean difference in depression scores, SMD = −0.25, 95% credible interval [CrI] = −0.41 to −0.08) and marginally better than CN (SMD = −0.43, 95% CrI = −0.85 to −0.00). While none of the interventions clearly had both high efficacy and acceptability, three combinations of interventions (CC, CN–CC, and CN–CC–ES) had a reasonable balance between efficacy and acceptability.

Discussion and Implications

Although interventions for caregiver depression in dementia are effective in general, the different components of interventions may not share the same efficacy and acceptability. In implementing interventions, policymakers may consider addressing CC first, introducing CN in a graded manner, and providing ES only when indicated. Future studies may also consider using network meta-analysis to gain additional insights on how to implement multicomponent interventions in geriatric care.

Efficacy of Guided iCBT for Depression and Mediation of Change by Cognitive Skill Acquisition

Guided internet CBT (iCBT) is a promising treatment for depression; however, it is less well known through what mechanisms iCBT works. Two possible mediators of change are the acquisition of cognitive skills and increases in behavioral activation. We report results of an 8-week waitlist controlled trial of guided iCBT, and test whether early change in cognitive skills or behavioral activation mediated subsequent change in depression. The sample was 89 individuals randomized to guided iCBT (n = 59) or waitlist (n = 30). Participants were 75% female, 72% Caucasian, and 33 years old on average. The PHQ9 was the primary outcome measure. Mediators were the Competencies of Cognitive Therapy Scale-Self Report and the Behavioral Activation Scale for Depression-Short Form. Treatment was Beating the Blues plus manualized coaching. Outcomes were analyzed using linear mixed models, and mediation with a bootstrap resampling approach. The iCBT group was superior to waitlist, with large effect sizes at posttreatment (Hedges' g = 1.45). Dropout of iCBT was 29% versus 10% for waitlist. In the mediation analyses, the acquisition of cognitive skills mediated subsequent depression change (indirect effect = -.61, 95% bootstrapped biased corrected CI: -1.47, -0.09), but increases in behavioral activation did not. iCBT is an effective treatment for depression, but dropout rates remain high. Change in iCBT appears to be mediated by improvements in the use of cognitive skills, such as critically evaluating and restructuring negative thoughts.

Cognitive Behavioral Therapy for Depression, Anxiety, and Stress in Caregivers of Dementia Patients: A Systematic Review and Meta-Analysis

Background and Objectives

There is limited evidence for the efficacy of cognitive behavioral therapy (CBT) in managing psychological morbidities in caregivers of dementia patients. To evaluate changes in dementia caregivers’ depression, anxiety, and stress following CBT. Also to assess quality of life, intervention adherence/satisfaction and therapy effectiveness using different formats, frequencies, and delivery methods.

Research Design and Methods

Studies were identified through electronic bibliographic searches (MEDLINE, EMBASE, CINAHL, PsycINFO, and the Cochrane Library) and from gray literature (Conference Proceedings Citation Index and clinicaltrials.gov). Data were pooled for meta-analysis.

Results

Twenty-five studies were included. Depression (standardized mean difference [SMD] = −0.34; 95% confidence interval [CI] −0.47 to −0.21; p < .001) and stress (SMD = −0.36; 95% CI: −0.52 to −0.20; p < .001) were significantly reduced after CBT, relative to comparator groups, while anxiety was not (SMD = 0.10; 95% CI: −0.18 to 0.39; p = .47). A subgroup analysis demonstrated that statistically significant reductions in depression and stress were limited to group, but not individual, formats. An additional subgroup analysis revealed that eight CBT sessions or fewer were equally effective as more than eight sessions at significantly reducing depression and stress, relative to comparator groups. Furthermore, analysis with independent samples t-tests demonstrated no statistically significant differences between mean changes in depression (MD = 0.79; 95% CI: −0.45 to 2.03; p = .21) and stress (MD = 0.21; 95% CI: −1.43 to 1.85; p = .80) when directly comparing CBT groups of ≤8 and >8 sessions.

Discussion and Implications

Group CBT provides small but significant benefits to caregivers’ depression and stress. Therapy cost-effectiveness may be improved by limiting therapy to group formats and eight sessions.

Testing Tele-Savvy: Protocol for a randomized controlled trial

Many informal caregivers of persons with dementia suffer adverse health consequences. Although established psychoeducation programs are known to benefit caregivers, attending in-person programs is challenging for them. To address this challenge, the Savvy Caregiver Program, an evidence-based psychoeducation program with demonstrated effectiveness for caregiving and disease-related outcomes, was transformed into an on-line program, Tele-Savvy. This article describes the rationale for and design of a prospective longitudinal randomized controlled trial (targeted N = 215), currently underway. The trial aims to establish Tele-Savvy's efficacy in (i) reducing the negative effects of caregiving on caregivers; (ii) promoting care recipients' quality of life; (iii) improving caregiver mastery; and to explore (iv) Tele-Savvy's efficacy among caregivers of different races/ethnicities. The mediating role of mastery will be assessed. Participants are randomized to the active condition (immediate Tele-Savvy participation), attention control, or usual care. Participants in the two latter conditions will complete Tele-Savvy 6 months post-baseline. Multilevel mixed effects models will be used to examine changes in outcomes and to model group by time (months since baseline) interactions. The exploratory aim will be addressed using analysis of covariance and qualitative analysis. This trial's results may be used by healthcare and community organizations to implement Tele-Savvy in dementia care, increasing caregivers' access to this evidence-based intervention.

Supporting carers of people with dementia: What is effective?

Carer stress is well documented, especially in those caring for individuals with dementia. A recommendation of all national dementia strategies is to provide excellent support and information to informal carers of people with dementia. NICE guidance suggests that a range of tailored interventions, including psychological input, psychoeducation and training courses, should be offered to reduce caregiver burden and stress, although good-quality outcome-based evidence is lacking. On the basis of a narrative review of the literature, we describe individual and multicomponent carer support packages and discuss their evidence base, reflecting on outcomes for carers. Multicomponent interventions have the best evidence for effectiveness.

Learning Objectives

• Consider the risks of both physical and psychological harm experienced by carers of people with dementia (often referred to as carer burden or caregiver burden)

• Be aware of the interventions available for the support of carers of people with dementia

• Consider the evidence for the effectiveness of these interventions and be aware of the limitations of the evidence

Implementation of a Psychosocial Intervention Program for Working Caregivers

The overall aim of this pilot study was to examine the feasibility and acceptability of a multicomponent, psychosocial intervention specifically designed to meet the unique needs of caregivers who are balancing caregiving duties with work responsibilities. Seventy-one family caregivers employed at a private, nonprofit institution in South Florida were randomized to either the Caregiver Workstation condition (n = 35) or a control condition (n = 36). Sixty-two caregivers completed the 5-month follow-up. Our results indicate that an intervention tailored to the time demands of a working caregiver is feasible, acceptable to caregivers, and has the potential to have positive long-term effects. Currently, there are limited data available regarding the benefits of employer programs for caregivers or the type of programs caregivers find most useful. This pilot study is the first step in developing a working caregiver intervention program that can be implemented on a broad-scale basis.

Effectiveness of Cognitive Behavioral Therapy for Caregivers of People with Dementia: A Systematic Review and Meta-Analysis

BACKGROUND AND PURPOSE

Caregivers endure tremendous physical, emotional, and financial burdens while caring for people with dementia. The current study aimed to estimate the effectiveness of cognitive behavioral therapy (CBT) for caregivers of people with dementia (CGPWD).

METHODS

Studies in the MEDLINE, EMBASE, Cochrane Library, Web of Science, and SCOPUS databases were screened. Studies with a randomized controlled design and which produced CBT outcomes for CGPWD were included in this study, and we investigated these outcomes.

RESULTS

The screening of abstracts of 263 studies resulted in 12 randomized controlled trials being included in this study. The mean age of the CGPWD ranged from 51.5 to 66.2 years. The caregiver role was most frequently adopted by a female spouse or daughter. CBT for the CGPWD resulted in positive effects on various conditions, including depression, anxiety, stress, and dysfunctional thoughts. Depression was the most commonly evaluated condition, and the Center for Epidemiologic Studies Depression Scale (CES-D) was most frequently used as an inventory for depressive symptoms. The mean differences between the baseline and postintervention CES-D scores were compared between the CBT-intervention and control groups. The CES-D score decreased significantly more in the CBT-intervention group than in the control group. The difference in pooled mean differences between the two groups was -4.98.

CONCLUSIONS

CBT is an efficient intervention tool for reducing the various emotional burdens experienced by CGPWD. This meta-analysis found that CBT significantly improved the depressive symptoms of CGPWD.

Empowering the dementia care workforce to manage behavioral symptoms of dementia: Development and training outcomes from the VOICE Dementia Care Program

Nonpharmacological approaches for managing behavioral symptoms of dementia remain widely underutilized, due in part to near-universal training needs reported by dementia caregivers in recent research. This article examines the development, core components, and initial outcomes of an evidence-informed, competency-based training program in the prevention and management of behavioral symptoms of dementia among care managers and nurses within an aging services system. The Vital Outcomes Inspired by Caregiver Engagement (VOICE) Dementia Care Training Program was developed based on identification of state-of-the-art approaches to managing behaviors through expert review of the literature and structured needs assessment. Results reveal robust improvements in knowledge, attitudes, and self-efficacy among training participants, with largest effect sizes (d = 1.8) on domains of knowledge and self-efficacy to manage behaviors. Findings support the feasibility and effectiveness of training in improving the abilities and confidence of aging services providers in dementia care and, specifically, in the nonpharmacological management of dementia-related behaviors.

An Online Program for Caregivers of Persons Living With Dementia: Lessons Learned

The population of individuals living with dementia and their caregivers and the need to provide caregiver training will increase in the next several decades. In-person caregiver educational programs are delimited by logistical and resource boundaries that could be overcome with online programs. The purpose of this qualitative descriptive study was to explore the acceptability and ways to improve the content and delivery of an online 7-week psychoeducational pilot program-Tele-Savvy. Thirty-six caregivers who completed the pilot were interviewed about their experience with Tele-Savvy and their suggestions for its improvement. Conventional content analysis allowed for the identification of three themes: barriers and facilitators to establishing rapport with participants and instructors, content enrichment and diversification, and structural refinement. These lessons learned directly from the caregivers provide evidence to guide the refinement of analogous online interventions and highlight the need for their wider availability.
