Cognitive Behavioral Therapies in older adults with depression and cognitive deficits: a systematic review

[Preventing emotional disorders in the elderly with programs based on cognitive-behavioral therapies]

The cognitive-behavioral approach is particularly well-suited to older people who are looking for a short-term therapeutic solution to many emotional problems, without necessarily resorting to psychotropic drugs. One of the major advantages of this type of psychological treatment is that it helps seniors develop coping skills that can be beneficial in both the short and long term. However, some adjustments are sometimes necessary to achieve this goal.

Anodal HD-tDCS on the dominant anterior temporal lobe and dorsolateral prefrontal cortex: clinical results in patients with mild cognitive impairment

OBJECTIVES

Mild cognitive impairment (MCI) is a neurocognitive disorder in which the cognitive and mental abilities of humans are declined. Transcranial direct-current stimulation (tDCS) is an emerging noninvasive brain stimulation technique aimed at neuromodulation. In this study, we investigate whether high-definition anodal tDCS stimulation (anodal HD-tDCS) in MCI patients in two different brain regions will be effective in improving cognitive function.

METHODS

This study was done as a randomized, double-blind clinical trial. Sixty MCI patients (clinically diagnosed by expert neurologists) were randomly divided into three groups. Two groups received 2-mA anodal HD-tDCS for 20 min for 2 weeks (5 consecutive days in each week, 10 days in total). In the first group (twenty patients), the left dorsolateral prefrontal cortex (left DLPFC) was targeted. In the second group (twenty patients), the target zone was the dominant anterior temporal lobe (DATL). The third group (twenty patients) formed the Sham group. The Montreal Cognitive Assessment (MoCA) and Quality of Life in Alzheimer's Disease (QoLAD) were considered as the outcome measures.

RESULTS

MCI patients obtained the highest MoCA mean scores in both left DLPFC and DATL groups versus the study baseline 2 weeks after the intervention. In addition, the MoCA mean scores of MCI patients were greater in both intervention groups compared to the Sham group up to 3 months post-stimulation (p-value ≤ 0.05). However, as we moved away from the first stimulation day, a decreasing trend in the MoCA mean scores was observed. Moreover, in the left DLPFC and DATL groups, higher QoLAD mean scores were observed 3-month post-stimulation, highlighting the effectiveness of anodal HD-tDCS in improving the quality of life in MCI patients.

CONCLUSION

In this research, it was shown that applying anodal HD-tDCS at left DLPFC and DATL brain regains for two successive weeks improves cognitive function in MCI patients (by obtaining higher values of MoCA scores) up to 3 months after the intervention compared to the Sham group. This illustrates the positive effects of HD-tDCS, as a non-pharmacological intervention, for improving cognitive function and quality of life in MCI patients.

SIGNIFICANCE

Two weeks after anodal HD-tDCS of the DLPFC and DATL brain regions, the MCI patients achieved the highest MoCA mean scores compared to the Sham group across all measurement intervals.

Gambling and Aging: An Overview of a Risky Behavior

Gambling is a field of study that has grown since the 2000s. Much research has focused on adolescents and youth as a vulnerable population. The rate of aging gamblers is increasing; however, evidence-based knowledge of this population is still too sparse. After introducing the issue (1), this article provides a narrative review of older adults' gambling through three sections: (2) older adult gamblers (age, characteristics, and motivations), (3) gambling as a risky decision-making situation, and (4) gambling disorder related to older adults. By drawing on the existing literature from a problematization perspective, this type of review can highlight complex and original research topics and provoke thought and controversy to generate avenues for future research. This narrative review provides an overview of the existing literature on gambling among older adults and offers perspectives on how aging can affect decision-making and thus gambling for this population. Older adults are a specific population, not only in terms of the consequences of gambling disorders but also in terms of the motivations and cognitions underlying gambling behaviors. Studies on behavioral science focusing on decision-making in older adults could help in the development of public policy in terms of targeted prevention.

The Feasibility of a Mindfulness Intervention for Depression in People with Mild Dementia: A Pilot Randomized Controlled Trial

OBJECTIVES

This preliminary study aimed to establish the feasibility of running an adapted Mindfulness Based Cognitive Therapy (MBCT) intervention for people with mild dementia and depression. It also aimed to conduct an exploratory analysis as to whether the MBCT intervention would lead to greater improvements in measures of depression, anxiety, quality of life and cognition, as compared to treatment as usual (TAU).

METHODS

A single-blind, multisite, feasibility randomized controlled trial was used. People with dementia and depression were recruited from participating memory services. Twenty participants were randomized to either an adapted MBCT and TAU group (n = 10) or TAU (n = 10). Measures of depression, anxiety, quality of life (QOL), and cognition were assessed at baseline and follow-up.

RESULTS

The intervention was feasible in terms of high attendance and low levels of attrition. It was not judged feasible to recruit enough participants within the recruitment time-frame. The MBCT group did not show significant improvements in depression, anxiety, QOL, and cognition at follow-up, as compared to TAU.

CONCLUSION

There is currently inadequate evidence to recommend this adapted MBCT intervention for people with dementia for the treatment of depression within memory services. The MBCT intervention needs redevelopment and piloting before further testing in an RCT.

Scaling Up Science-Based Care for Depression and Unhealthy Alcohol Use in Colombia: An Implementation Science Project

BACKGROUND

Mental disorders are a major cause of the global burden of disease and significantly contribute to disability and death. This challenge is particularly evident in low- and middle-income countries (LMICs), where >85% of the world's population live. Latin America is one region comprising LMICs where the burden of mental disorders is high and the availability of mental health services is low. This is particularly evident in Colombia, a country with a long-standing history of violence and associated mental health problems.

METHODS

This article describes the design of a multisite implementation science project, "Scaling Up Science-Based Mental Health Interventions in Latin America" (also known as the DIADA project), that is being conducted in six primary care systems in Colombia. This project, funded via a cooperative agreement from the National Institute of Mental Health, seeks to implement and assess the impact of a new model for promoting widespread access to mental health care for depression and unhealthy alcohol use within primary care settings and building an infrastructure to support research capacity and sustainability of the new service delivery model in Colombia. This care model centrally harnesses mobile health technology to increase the reach of science-based mental health care for depression and unhealthy alcohol use.

RESULTS

This initiative offers great promise to increase capacity for providing and sustaining evidence-based treatment for depression and unhealthy alcohol use in Colombia.

NEXT STEPS

This project may inform models of care that can extend to other regions of Latin America or other LMICs.

The depressed frail phenotype as a risk factor for mortality in older adults: A prospective cohort in Peru

INTRODUCTION

Frailty and depression can coexist as depressed frail phenotype, useful for the comprehensive evaluation of older adults and prevention of adverse outcomes. The objective of this study was to evaluate the role of the depressed frail phenotype and its components as risk factors for mortality in older adults of the Centro Médico Naval (CEMENA) of Peru during 2010-2015.

MATERIAL AND METHODS

We carried out a secondary data analysis of a prospective cohort that included older adults (60 years and older) treated in the Geriatrics service of CEMENA between the years 2010-2015. Frailty was defined as the presence of three or more Fried phenotype criteria and depression was determined using a Yesavage ultrashort scale score of three or more. The presence of both conditions was defined as depressed frail phenotype. In addition, sociodemographic characteristics, medical and personal history, and performance-based measures were included. We employed crude and adjusted Cox regression models to evaluate the association of interest and estimate Hazard Ratios (HR) with their respective 95% confidence intervals (95% CI).

RESULTS

946 older adults were included in the analysis, with a mean age of 78.0 ± 8.5 years. 559 (59.1%) were male, 148 (15.6%) were found to be frail, 231 (24.4%) had depressive symptoms, 105 (11.1%) had depressed frail phenotype, and 79 (8.3%) participants died during follow-up. The adjusted Cox regression analysis revealed that depressed frail phenotype (HR = 3.53; 95%CI: 2.07-6.00; p < 0.001) was a risk factor for mortality in older adults.

CONCLUSIONS

The depressed frail phenotype was associated with a higher risk of mortality in older adults. It is necessary to develop longitudinal studies that allow estimating this phenotype's impact on mortality and evaluate interventions to improve quality of life and reduce the risk of adverse outcomes.

Barriers and facilitators of engagement in psychological therapies among older adults with depression: A systematic review and thematic synthesis

WHAT IS KNOWN ON THE SUBJECT?: The utilization rate of psychological therapies is low in older adults with depression. The barriers and facilitators to engaging in psychological therapies experienced by older adults with depression are unclear. WHAT DOES THE PAPER ADD TO EXISTING KNOWLEDGE?: Personal suitability for therapy engagement, practical abilities, personal therapy preferences, and familiarity with psychological therapies are associated with psychological therapy engagement. Psychological therapists can also impact psychological therapy engagement among older adults with depression. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Proving the effectiveness and suitability of chosen psychological therapies is important for improving therapy engagement. Strategies for handling functional impairments among older adults with depression are necessary for engaging this population in psychological therapies. Although in-home psychological therapies are accessible, barriers to handling the technologies used for delivering the therapies should be addressed. More methods of accessing information about psychological therapies should be available to older adults in order for them to increase their knowledge on the topic. Psychological therapists should have positive attitudes and the competence to treat depression in older adults.

ABSTRACT

INTRODUCTION: Although psychological therapies are preferred by older adults, the utilization rate of these therapies is significantly low in older adults with depression. Understanding the barriers and facilitators to engaging in psychological therapies experienced by older adults is important for improving utilization rates.

AIM

This review aimed to explore the barriers and facilitators to engaging in psychological therapies experienced by older adults with depression.

METHODS

A systematic review of qualitative studies on psychological therapy engagement among older adults with depression. Relevant published studies and grey literature were searched. The Critical Appraisal Skills Programme tool was used to assess the quality of the included studies. The results of the included studies were synthesized using thematic synthesis.

RESULTS

Personal suitability for therapy engagement, practical abilities, personal therapy preferences and familiarity with psychological therapies was associated with therapy engagement. Therapists' competencies also affected therapy engagement.

DISCUSSION

Older adult's personal health status and requirements for psychological therapy should be considered.

IMPLICATIONS FOR PRACTICE

Mental health practitioners should consider whether specific psychological therapies are beneficial and acceptable for older adults. Improvements are needed in older adult's familiarity with psychological therapies and the ability of therapists to address the mental problems of older adults.

Longitudinal Changes of Cognitive Deficits and Treatment Outcome of Cognitive Behavioral Therapy for Major Depression

ABSTRACT

The current study examined neuropsychological changes over the course of cognitive behavioral therapy (CBT) in outpatients with major depressive disorder and the influence of cognitive deficits as predictors of clinical outcome in depression. A neuropsychological test battery was carried out on depressed outpatients (N = 54) at the beginning and at the end of CBT. Small improvements were found in divided attention, figural memory, and processing speed from pre- to posttreatment. Cognitive deficits in executive functions before treatment predicted the clinical outcome at the end of CBT. The present study reveals that attention and memory deficits are most likely to improve over the course of treatment, whereas executive functions remain stable in the long term. Depressed patients with worse executive functions at the beginning of treatment seem to benefit more from long-term CBT therapy.

Interactions between Personality, Depression, Anxiety and Cognition to Understand Early Stage of Alzheimer's Disease

The multifaceted nature of Alzheimer's disease (AD) and Mild cognitive impairment (MCI) can lead to wide inter-individual differences in disease manifestation in terms of brain pathology and cognition. The lack of understanding of phenotypic diversity in AD arises from a difficulty in understanding the integration of different levels of network organization (i.e. genes, neurons, synapses, anatomical regions, functions) and in inclusion of other information such as neuropsychiatric characteristics, personal history, information regarding general health or subjective cognitive complaints in a coherent model. Non-cognitive factors, such as personality traits and behavioral and psychiatric symptoms, can be informative markers of early disease stage. It is known that personality can affect cognition and behavioral symptoms. The aim of the paper is to review the different types of interactions existing between personality, depression/anxiety, and cognition and cognitive disorders at behavioral and brain/genetic levels.

Treatment Approach and Modalities for Management of Depression in Older People

Depression is common in older people, and while the approach to treatment is similar to a younger population, there are several additional treatment considerations to make based on comorbidities and cognitive impairment. Evidence-based psychotherapies such as cognitive behavioral therapy, interpersonal psychotherapy, and problem-solving therapy are recommended for mild-moderate depression in older people; however, the efficacy of these are limited in very old patients (older than 75 years of age) and those with cognitive impairment. Additionally, neuromodulation treatments such as electroconvulsive therapy and transcranial magnetic stimulation could prove beneficial for specific older people with depression. Use of pharmacotherapy that has demonstrated to be safe in older adults, as well as agents with adequate clinical experience in this population, should be considered based on patient-specific characteristics. Because of generally more complex medication regimens, risks of pharmacotherapy should be minimized with careful dosing strategies and special attention to avoid significant drug-drug interactions. While some data are available, antidepressant combination or augmentation strategies are less well studied in older people who fail to achieve remission or those with treatment-resistant depression, compared with younger populations.

Management of mild cognitive impairment (MCI): The need for national and international guidelines

Objectives: To review available evidence of pharmacological and non-pharmacological treatment for MCI and analyse information and limitations in national and international guidelines.Methods: Experts from several European countries conducted a qualitative review of the literature on MCI and treatments for MCI, as well as respective chapters in national and international guidelines on dementia/MCI. Psychotherapeutic/psychosocial treatments were excluded from the review.Results: Consensus diagnostic criteria for MCI are available, making early recognition and accurate classification of MCI subtypes possible. MCI can be identified in a primary care setting. Further corroboration and differential diagnosis should be done at specialist level. Mixed pathologies are the rule in MCI, thus a multi-target treatment approach is a rational strategy. Promising evidence has been generated for multi-domain interventions. Limited evidence is available for different pharmacological classes that have been investigated in MCI clinical trials (e.g. acetylcholinesterase inhibitors). EGb 761^® improved symptoms in some clinical trials; it is the only pharmacological treatment recommended in existing guidelines for the symptomatic treatment of MCI.Conclusions: MCI is recognised as an important treatment target and some recent national guidelines have considered symptomatic treatment recommendations for MCI. However, more needs to be done, especially at an international level.

Altered Resting-State Functional Connectivity of Multiple Networks and Disrupted Correlation With Executive Function in Major Depressive Disorder

Background: Major depressive disorder (MDD) is one of the most common and costly psychiatric disorders. In addition to significant changes in mood, MDD patients face an increased risk of developing cognitive dysfunction. It is important to gain an improved understanding of cognitive impairments and find a biomarker for cognitive impairment diagnosis in MDD.

Methods: One hundred MDD patients and 100 normal controls (NCs) completed resting-state fMRI (rs-fMRI) scan, in which 34 MDD patients and 34 NCs had scores in multiple cognitive domains (executive function, verbal fluency, and processing speed). Twenty-seven regions of interest from the default mode network (DMN), central executive network (CEN), salience network (SN), and limbic system (LS) were selected as seeds for functional connectivity (FC) analyses with the voxels in the whole brain. Finally, partial correlations were conducted for cognitive domain scores and FCs with significant differences between the MDD and NC groups.

Results: Significant FC differences between groups were identified among the seeds and clusters in the DMN, CEN, LS, visual network, somatomotor network, ventral attention network, and dorsal attention network. In the MDD patients, the magnitude of the Stroop interference effect was positively correlated with the illness duration, and the illness duration was negatively correlated with the FC between the right ventral hippocampal gyrus and the left inferior frontal gyrus. However, the correlation between the Stroop interference effect and the FC of the right anterior prefrontal cortex with the left cerebellum_4_5 was disrupted in these patients.

Conclusions: The MDD patients have altered FCs among multiple brain networks and a disrupted correlation between the FC of prefrontal cortex and executive function. The disrupted correlation could present before the symptoms develop and may be the core process in the development of executive function impairment.

Depression, cognitive, and functional outcomes of Problem Adaptation Therapy (PATH) in older adults with major depression and mild cognitive deficits

OBJECTIVES

Antidepressants have limited efficacy in older adults with depression and cognitive impairment, and psychosocial interventions for this population have been inadequately investigated. Problem Adaptation Therapy (PATH) is a psychosocial intervention for older adults with major depression, cognitive impairment, and disability.

DESIGN

This study tests the efficacy of PATH versus Supportive Therapy for Cognitively Impaired Older Adults (ST-CI) in reducing depression (Montgamery Asberg Depression Rating Scale [MADRS]) and disability (World Health Organization Disability Assessments Schedule-II [WHODAS-II]) and improving cognitive outcomes (Mini Mental State Examination [MMSE]) over 24 weeks (12 weeks of treatment and 12-week post-treatment follow-up).

SETTING

Participants were recruited through collaborating community agencies of Weill Cornell Institute of Geriatric Psychiatry. Both interventions and all research assessments were conducted at home.

PARTICIPANTS

Thirty-five older adults (age ≥ 65 years) with major depression and cognitive impairment no dementia (CIND).

INTERVENTIONS

PATH aims to increase emotion regulation by incorporating a problem-solving approach, teaching compensatory strategies, and inviting caregiver participation. Supportive Therapy aims to facilitate the expression of affect, as well as promote empathy.

MEASUREMENTS

Depression was measured using the MADRS, disability using the WHODAS-II, and cognition using the MMSE.

RESULTS

PATH participants showed significantly greater reduction in MADRS total score (7.04 points at 24 weeks, treatment group by time interaction: F[1,24.4] = 7.61, p = 0.0108), greater improvement in MMSE total score (2.30 points at 24 weeks, treatment group by time interaction: F[1,39.8] = 13.31, p = 0.0008), and greater improvement in WHODAS-II total score (2.95 points at 24 weeks, treatment group by time interaction: F[1,89] = 4.93, p = 0.0290) than ST-CI participants over the 24-week period.

CONCLUSIONS

PATH participants had better depression, cognitive, and disability outcomes than ST-CI participants over 6 months. PATH may provide relief to depressed older adults with CIND who currently have limited treatment options.

Correlates of Health-Related Quality of Life Among Chinese Older Adults with Mild Cognitive Impairment

Purpose

This study aimed to assess the health-related quality of life (HRQoL) and identify the important correlates of HRQoL in older Chinese adults with mild cognitive impairment (MCI).

Patients and methods

A cross-sectional study design was adopted. A total of 204 older adults with MCI were enrolled in this study. HRQoL was evaluated by the Quality of Life-Alzheimer's disease. Hierarchical regression analysis was conducted to investigate the sociodemographic, disease-related, psychological, and behavioral factors associated with the HRQoL of individuals with MCI.

Results

Hierarchical regression analysis indicated that old age (Beta = -0.131, p =0.024), low income (Beta = 0.128, p = 0.032), depressive symptoms (Beta = -0.564, p < 0.001), and poor sleep quality (Beta = -0.169, p =0.004) were significantly associated with the HRQoL of individuals with MCI.

Conclusion

Caring for older Chinese adults with MCI should focus on sociodemographically disadvantaged groups with advanced age and low income. Rehabilitation programs that effectively alleviate depressive symptoms and improve sleep quality should be applied to older adults with MCI to enhance their HRQoL.

Psychological Treatment for Depressive Disorder

Depression is highly prevalent and causes unnecessary human suffering and economic loss. Therefore, its treatment and prevention are of utmost importance. There are several advantages of using psychotherapy either by itself or combined with pharmacological treatment methods in the treatment of depression. First, it is well known that combining biological treatment with psychosocial methods increases the chances of recovery. Second, in some individuals, psychotherapy continues to be the only solution. Third, the use of antidepressants contains some safety risks and side effects, but psychotherapy does not. Fourth, clinically, depressive patients prefer psychotherapy to drug therapy. Use of a depression-focused psychotherapy alone is recommended as an initial treatment choice for patients with mild to moderate depression, with clinical evidence supporting the use of cognitive behavioral therapy (CBT), interpersonal psychotherapy (IPT), psychodynamic psychotherapy (PDP), and problem-solving therapy (PST) in individual and group formats. Important developments took place within the past 20 years in the psychotherapy of depression. In the present chapter, we introduced several key issues, such as, Are all psychotherapies equally effective? Who benefits from psychotherapies? Is telepsychotherapy effective? Finally, we introduce the psychotherapy for special populations.

Suicide risk in informal carers of people living with dementia

With an ageing population comes an increasing risk of illnesses such as dementia and a growing need for care. There are 670,000 informal, unpaid carers in the UK, reducing costs for health and social care services but presenting other concerns for healthcare professionals. Carer burden and carer stress are well-documented concepts, and can lead to depression and a risk of suicide in some individuals. It is important that this risk is considered when supporting informal carers of people living with dementia. Admiral Nurses work with families living with dementia to provide the one-to-one support and expert guidance they need to manage. This article discusses a case study that highlights how caring can affect an individual, leading to thoughts of suicide. It also demonstrates how an Admiral Nurse could support the carer in a relationship-centred way, using appropriate interventions to avoid crisis. The article offers implications for practice and provides recommendations for nurses working in this field.

A Pilot Study of Metacognitive Training (D-MCT) for Older Adults with Depression

Abstract. Depression remains one of the most common psychological disorders among older adults. Their response to antidepressants: however, is often unsatisfactory, and despite the proven efficacy of psychotherapies, a large treatment gap remains. Metacognitive Training for Depression (D-MCT) is a low-threshold group intervention. This article examines the feasibility, acceptance, and effects of D-MCT as an add-on intervention among a group of older adults (55+ years; N = 116). Participants completed measures of depression and dysfunctional attitudes, and provided subjective appraisals of the training. Per protocol analyses (n = 55) revealed a significant decrease in depressive symptoms (d = 1.06) and cognitive biases (d = 0.33). The findings demonstrate the feasibility and acceptance of D-MCT among older adults with depression.

Advances in Psychotherapy for Depressed Older Adults

PURPOSE OF REVIEW

We review recent advances in psychotherapies for depressed older adults, in particular those developed for special populations characterized by chronic medical illness, acute medical illness, cognitive impairment, and suicide risk factors. We review adaptations for psychotherapy to overcome barriers to its accessibility in non-specialty settings such as primary care, homebound or hard-to-reach older adults, and social service settings.

RECENT FINDINGS

Recent evidence supports the effectiveness of psychotherapies that target late-life depression in the context of specific comorbid conditions including COPD, heart failure, Parkinson's disease, stroke and other acute conditions, cognitive impairment, and suicide risk. Growing evidence supports the feasibility, acceptability, and effectiveness of psychotherapy modified for a variety of health care and social service settings. Research supports the benefits of selecting the type of psychotherapy based on a comprehensive assessment of the older adult's psychiatric, medical, functional, and cognitive status, and tailoring psychotherapy to the settings in which older depressed adults are most likely to present.

AIDE-Acute Illness and Depression in Elderly Patients. Cognitive Behavioral Group Psychotherapy in Geriatric Patients With Comorbid Depression: A Randomized, Controlled Trial

BACKGROUND

Comorbid depression is highly prevalent in geriatric patients and associated with functional loss, frequent hospital re-admissions, and a higher mortality rate. Cognitive behavioral psychotherapy (CBT) has shown to be effective in older depressive patients living in the community. To date, CBT has not been applied to older patients with acute physical illness and comorbid depression.

OBJECTIVES

To evaluate the effectiveness of CBT in depressed geriatric patients, hospitalized for acute somatic illness.

DESIGN

Randomized controlled trial with waiting list control group.

SETTING

Postdischarge intervention in a geriatric day clinic; follow-up evaluations at the patients' homes.

PARTICIPANTS

A total of 155 randomized patients, hospitalized for acute somatic illness, aged 82 ± 6 years and suffering from depression [Hospital Anxiety and Depression Scale (HADS) scores >7]. Exclusion criteria were dementia, delirium, and terminal state of medical illness.

INTERVENTION

Fifteen, weekly group sessions based on a CBT manual. Commencement of psychotherapy immediately after discharge in the intervention group and a 4-month waiting list interval with usual care in the control group.

MEASUREMENTS

HADS depression total score after 4 months. Secondary endpoints were functional, cognitive, psychosocial and physical status, resource utilization, caregiver burden, and amount of contact with physician.

RESULTS

The intervention group improved significantly in depression scores (HADS baseline 18.8; after 4 months 11.4), whereas the control group deteriorated (HADS baseline 18.1; after 4 months 21.6). Significant improvement in the intervention group, but not in the control group, was observed for most secondary outcome parameters such as the Barthel and Karnofsky indexes. Intervention effects were less pronounced in patients with cognitive impairment or acute fractures.

CONCLUSIONS

CBT is feasible and highly effective in geriatric patients. The benefits extend beyond effective recovery and include improvement in physical and functional parameters. Early diagnosis, good access to psychotherapy, and early intervention could improve care for depressive older patients.

World Health Organization disability assessment schedule 2.0: An international systematic review

PURPOSE

This systematic review examines research and practical applications of the World Health Organization Disability Assessment Schedule (WHODAS 2.0) as a basis for establishing specific criteria for evaluating relevant international scientific literature. The aims were to establish the extent of international dissemination and use of WHODAS 2.0 and analyze psychometric research on its various translations and adaptations. In particular, we wanted to highlight which psychometric features have been investigated, focusing on the factor structure, reliability, and validity of this instrument.

METHOD

Following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) methodology, we conducted a search for publications focused on "whodas" using the ProQuest, PubMed, and Google Scholar electronic databases.

RESULTS

We identified 810 studies from 94 countries published between 1999 and 2015. WHODAS 2.0 has been translated into 47 languages and dialects and used in 27 areas of research (40% in psychiatry).

CONCLUSIONS

The growing number of studies indicates increasing interest in the WHODAS 2.0 for assessing individual functioning and disability in different settings and individual health conditions. The WHODAS 2.0 shows strong correlations with several other measures of activity limitations; probably due to the fact that it shares the same disability latent variable with them. Implications for Rehabilitation WHODAS 2.0 seems to be a valid, reliable self-report instrument for the assessment of disability. The increasing interest in use of the WHODAS 2.0 extends to rehabilitation and life sciences rather than being limited to psychiatry. WHODAS 2.0 is suitable for assessing health status and disability in a variety of settings and populations. A critical issue for rehabilitation is that a single "minimal clinically important .difference" score for the WHODAS 2.0 has not yet been established.

Psychological Treatment of Depression in People Aged 65 Years and Over: A Systematic Review of Efficacy, Safety, and Cost-Effectiveness

Objectives

Depression in elderly people is a major public health concern. As response to antidepressants is often unsatisfactory in this age group, there is a need for evidence-based non-pharmacological treatment options. Our objectives were twofold: firstly, to synthesize published trials evaluating efficacy, safety and cost-effectiveness of psychological treatment of depression in the elderly and secondly, to assess the quality of evidence.

Method

The electronic databases PubMed, EMBASE, Cochrane Library, CINAL, Scopus, and PsycINFO were searched up to 23 May 2016 for randomized controlled trials (RCTs) of psychological treatment for depressive disorders or depressive symptoms in people aged 65 years and over. Two reviewers independently assessed relevant studies for risk of bias. Where appropriate, the results were synthesized in meta-analyses. The quality of the evidence was graded according to GRADE (Grading of Recommendations Assessment, Development and Evaluation).

Results

Twenty-two relevant RCTs were identified, eight of which were excluded from the synthesis due to a high risk of bias. Of the remaining trials, six evaluated problem-solving therapy (PST), five evaluated other forms of cognitive behavioural therapy (CBT), and three evaluated life review/reminiscence therapy. In frail elderly with depressive symptoms, the evidence supported the efficacy of PST, with large but heterogeneous effect sizes compared with treatment as usual. The results for life-review/reminiscence therapy and CBT were also promising, but because of the limited number of trials the quality of evidence was rated as very low. Safety data were not reported in any included trial. The only identified cost-effectiveness study estimated an incremental cost per additional point reduction in Beck Depression Inventory II score for CBT compared with talking control and treatment as usual.

Conclusion

Psychological treatment is a feasible option for frail elderly with depressive symptoms. However, important questions about efficacy, generalizability, safety and cost-effectiveness remain.

Non-pharmacological interventions for adults with mild cognitive impairment and early stage dementia: An updated scoping review

The purpose of this scoping review was to examine the science related to non-pharmacological interventions designed to slow decline for older adults with Mild Cognitive Impairment or early-stage dementia. We reviewed 32 unique randomized controlled trials that employed cognitive training (remediation or compensation approaches), physical exercise, or psychotherapeutic interventions that were published before November 2014. Evidence suggests that cognitive training focused on remediation and physical exercise interventions may promote small improvements in selected cognitive abilities. Cognitive training focused on compensation interventions and selected psychotherapeutic interventions may influence how cognitive changes impact daily living. However, confidence in these findings is limited due to methodological limitations. To better assess the value of non-pharmacological interventions for this population, we recommend: (1) adoption of universal criteria for "early stage cognitive decline" among studies, (2) adherence to guidelines for the conceptualization, operationalization, and implementation of complex interventions, (3) consistent characterization of the impact of interventions on daily life, and (4) long-term follow-up of clinical outcomes to assess maintenance and meaningfulness of reported effects over time.
