Meta-analysis of problem solving therapy for the treatment of major depressive disorder in older adults

Comparative Effectiveness of Clinician- Versus Peer-Supported Problem-Solving Therapy for Rural Older Adults With Depression

OBJECTIVE

Self-guided and peer-supported treatments for depression among rural older adults may address some common barriers to treatment. This pilot study compared the effect on depression of peer-supported, self-guided problem-solving therapy (SG-PST) with case management problem-solving therapy (CM-PST) among older adults in rural California.

METHODS

Older adults with depression (N=105) received an introductory PST session with a clinician, followed by 11 sessions of CM-PST with a clinician (N=85) or SG-PST with a peer counselor (N=20).

RESULTS

Both interventions resulted in clinically significant improvement in depression by week 12. Depression scores in the CM-PST group dropped by 4.1 points more than in the SG-PST group between baseline and week 12 (95% CI=0.99-7.22, p<0.001, Hedges's g=1.08).

CONCLUSIONS

The results suggest that peer-supported SG-PST is a viable, acceptable option for rural older adults with depression as a second-line treatment if access to clinicians is limited.

Study of a PST-trained voice-enabled artificial intelligence counselor for adults with emotional distress (SPEAC-2): Design and methods

BACKGROUND

Novel and scalable psychotherapies are urgently needed to address the depression and anxiety epidemic. Leveraging artificial intelligence (AI), a voice-based virtual coach named Lumen was developed to deliver problem solving treatment (PST). The first pilot trial showed promising changes in cognitive control measured by functional neuroimaging and improvements in depression and anxiety symptoms.

METHODS

To further validate Lumen in a 3-arm randomized clinical trial, 200 participants with mild-to-moderate depression and/or anxiety will be randomly assigned in a 2:1:1 ratio to receive Lumen-coached PST, human-coached PST as active treatment comparison, or a waitlist control condition where participants can receive Lumen after the trial period. Participants will be assessed at baseline and 18 weeks. The primary aim is to confirm neural target engagement by testing whether compared with waitlist controls, Lumen participants will show significantly greater improvements from baseline to 18 weeks in the a priori neural target for cognitive control, right dorsal lateral prefrontal cortex engaged by the go/nogo task (primary superiority hypothesis). A secondary hypothesis will test whether compared with human-coached PST participants, Lumen participants will show equivalent improvements (i.e., noninferiority) in the same neural target from baseline to 18 weeks. The second aim is to examine (1) treatment effects on depression and anxiety symptoms, psychosocial functioning, and quality of life outcomes, and (2) relationships of neural target engagement to these patient-reported outcomes.

CONCLUSIONS

This study offers potential to improve the reach and impact of psychotherapy, mitigating access, cost, and stigma barriers for people with depression and/or anxiety.

Mental Health Treatment Use, Perceived Treatment Need, and Reasons for Non-Use Among U.S. Adults with Serious Suicidal Thoughts During the COVID-19 Pandemic

Analyzing the 2021 National Survey on Drug Use and Health data with generalized linear models, we examined: (1) COVID pandemic-related and other correlates of mental health treatment use and unmet perceived treatment need among U.S. adults who experienced serious suicidal thoughts (N = 3,177); and (2) correlates of self-reported reasons for not receiving treatment. We found that 61% used any mental health treatment, and 48% of users and 37% of nonusers reported perceived treatment need. Significant correlates of treatment use were demographic factors, insurance, major depressive disorder, and illicit drug use disorder. Significant correlates of perceived treatment need were age 18-34, some college education, and major depressive episode. Perceived negative effect of the COVID pandemic on mental health was a significant factor for both treatment use and perceived need. The most frequent reasons for not getting treatment were the cost of treatment or lack of insurance and stigma-related concerns.

Hoarding Symptoms in Late Life Depression are Associated With Greater Executive Dysfunction and Disability and Poorer Response to Depression Treatment

OBJECTIVES

Late life depression (LLD) and hoarding disorder (HD) are common in older adults and characterized by executive dysfunction and disability. We aimed to determine the frequency of co-occurring HD in LLD and examine hoarding severity as an additional contributor to executive dysfunction, disability, and response to psychotherapy for LLD.

DESIGN

Cross-sectional.

SETTING

Outpatient psychiatry program.

PARTICIPANTS

Eighty-three community-dwelling adults ages 65-90 with LLD.

INTERVENTION

Problem-solving therapy.

MEASUREMENTS

Measures of executive function, disability, depression, and hoarding severity were completed at post-treatment. Pearson's chi-squared tests evaluated group differences in rates of cognitive impairment, disability, and depression treatment response between participants with HD (LLD+HD) and LLD only. Separate linear regressions assessed associations between hoarding severity and executive function, disability, and psychotherapy response. Covariates included age, education, gender, and depression severity.

RESULTS

30.1% (25/83) of LLD participants met HD criteria. Relative to LLD, LLD+HD participants demonstrated greater impairment rates on measures of executive function (Letter-Number-Sequencing, X2(1)=4.0, p = 0.045; Stroop-Interference, X2(1) = 4.8, p = 0.028). Greater hoarding severity was associated with poorer executive functioning performance (Letter-Number-Sequencing (t[70] = -2.1, β = -0.05, p = 0.044), Digit-Span (t[71] = -2.4, β = -0.07, p = 0.019), Letter-Fluency (t[ 71] = -2.8, β = -0.24, p = 0.006)). Rates of disability were significantly higher for LLD+HD (88.0%) than LLD (62.3%), (X2[1] = 5.41, p = 0.020) and higher hoarding severity was related to greater disability (t[72] = 2.97, β = 0.13, p = 0.004). Depression treatment response rates were significantly lower for LLD+HD (24.0%) compared to LLD (48.3%), X2(1) = 4.26, p = 0.039, and HD status predicted psychotherapy response, t(67) = -2.15, β = -15.6, p = 0.035.

CONCLUSIONS

We found 30.1% co-occurrence of HD in LLD, which was accompanied by greater executive dysfunction, disability, and poorer response to depression treatment. Results underscore the need for increased screening of hoarding behaviors in LLD and tailored interventions for this LLD+HD group.

PROTOCOL: Non-pharmacological interventions for older people with a diagnosis of depression: An evidence and gap map

This is the protocol for an evidence and gap map. The objectives are as follows: To map available randomized control trials, economic evaluations, and systematic reviews that assess the effectiveness and cost-effectiveness of non-pharmacological interventions for older people with a diagnosis of depression and identify any existing gaps in the evidence that can inform future research.

Association between changes in depressive symptoms and falls: The China health and retirement longitudinal study (CHARLS)

PURPOSE

This study aimed to investigate the impact of depressive symptoms and changes in depressive status on falls among middle-aged and older population in China.

METHODS

We used two waves of interview data (time 1 [T1] and time 2 [T2], 2 years from T1) from a nationally representative sample of the China Health and Retirement Longitudinal Study (CHARLS), which included a total of 14,356 participants (male 6859; mean age: 59.5 ± 9.3 years). Depressive symptoms were assessed using the 10-item short form of the Center for Epidemiologic Studies Depression Scale (CES-D-10). Participants were categorized into four groups based on changes in their CES-D-10 scores over a 2-year follow-up period. Self-reported falls were evaluated, and logistic regression models and restricted cubic splines (RCS) were employed to examine the relationship between depressive symptoms and fallen.

RESULTS

Participants who had experienced falls had higher CES-D-10 scores and were more likely to have depressive symptoms. Depressive symptoms at T1 were significantly associated with falls during the follow-up period. After adjusting for covariables, increasing CES-D-10 scores were associated with higher adjusted odds ratios (ORs) for falling prevalence: 1.230 (95 % CI, 1.041-1.453), 1.579 (95 % CI, 1.331-1.873), 1.745 (95 % CI, 1.472-2.070), and 2.366 (95 % CI, 1.972-2.838). Participants who experienced depressive symptoms at either T1 or T2, as well as those with persistent depressive symptoms from T1 to T2, were both at higher risk for future falls. The worsening of depressive symptoms significantly increased the likelihood of falls.

CONCLUSION

This study revealed a significant association between depressive symptoms and changes in depressive status with subsequent falls in older adults. The heightened fall risk among individuals with depressive symptoms underscores the importance of addressing mental health as an integral part of comprehensive fall prevention strategies.

Depression during the COVID-19 pandemic among older Canadians with peptic ulcer disease: Analysis of the Canadian Longitudinal Study on Aging

The COVID-19 pandemic and associated public health measures have exacerbated many known risk factors for depression that may be particularly concerning for individuals with chronic health conditions, such as peptic ulcer disease (PUD). In a large longitudinal sample of older adults with PUD, the current study examined the incidence of depression during the pandemic among those without a pre-pandemic history of depression (n = 689) and the recurrence of depression among those with a history of depression (n = 451). Data came from four waves of the Canadian Longitudinal Study on Aging (CLSA). Multivariate logistic regression analyses were conducted to identify factors associated with incident and recurrent depression. Among older adults with PUD and without a history of depression, approximately 1 in 8 (13.0%) developed depression for the first time during the COVID-19 pandemic. Among those with a history of depression, approximately 1 in 2 (46.6%) experienced depression during the pandemic. The risk of incident depression and recurrent depression was higher among those who were lonely, those with functional limitations, and those who experienced an increase in family conflict during the pandemic. The risk of incident depression only was higher among women, individuals whose income did not satisfy their basic needs, those who were themselves ill and/or those whose loved ones were ill or died during the pandemic, and those who had disruptions to healthcare access during the pandemic. The risk of recurrent depression only was higher among those with chronic pain and those who had difficulty accessing medication during the pandemic. Implications for interventions are discussed.

A Review of Therapeutics for Treatment-Resistant Depression in the Older Adult

One-third of older adults with depression meet criteria for treatment resistance, typically defined as a lack of response to two or more adequate trials of an antidepressant. Treatment resistance contributes to an unfavorable prognosis, compromised medical outcomes, heightened disability, accelerated cognitive decline, and an elevated risk of developing dementia. Despite this significant morbidity, evidence is sparse for how to proceed with treatment in this population. Non-pharmacologic therapy (e.g., diet, psychotherapy) can be utilized as adjunctive therapy, despite little published evidence of benefit, given that the risks are low. Pharmacotherapy trials in the treatment-resistant late-life depression population lack strong methods and external validity; however, the use of venlafaxine as monotherapy and add-on therapy, as well as lithium, bupropion, or aripiprazole as add-on therapy to standard antidepressant therapy, have enough evidence that a trial with appropriate monitoring is a prudent strategy. Electroconvulsive therapy remains a well-studied safe therapy, especially when used as maintenance treatment once an initial cycle is completed but is traditionally underutilized in the treatment-resistant late-life depression population. Ensuring non-pharmacologic and pharmacologic strategies are optimized and given a sufficient trial in those with treatment-resistant late-life depression is the best we can do for this vulnerable population.

The effects of modified problem-solving therapy on depression, coping, and self-efficacy in elderly nursing home residents

Background

With the increasing trend of aging, the mental health problems of the elderly require urgent attention. Depression is a common psychological problem of the elderly, which affects their quality of life and physical health. Problem-solving therapy can effectively improve depression in the elderly, but there are few studies on problem-solving therapy for depression in the elderly in China. The purpose of this study was to evaluate the effects of modified problem-solving therapy (MPST) on depression, coping and self-efficacy in elderly nursing home residents.

Methods

This study was a randomized controlled trial. A total of 60 older adults from two nursing homes were recruited to participate in this study and randomly assigned to the intervention group (MPST) or the control group (usual care). The intervention lasted 8 weeks, and information on depression, coping skills, and self-efficacy was collected before the intervention, immediately after the intervention, and 3 months after the intervention. Repeated measures ANOVA was used to compare changes at multiple time points between the two groups. If the interaction effect (group * time) was significant, independent samples t-test was used to compare the differences in outcome indicators between groups at post-intervention and 3 months post-intervention.

Results

Compared to the control group, depression scores in the intervention group were significantly lower at the end of the intervention and remained significantly lower than the control group 3 months post-intervention (p < 0.05). Negative coping and self-efficacy in the intervention group also improved significantly at the end of the intervention, and 3 months post-intervention, while positive coping in the two groups did not differ significantly at 3 months post-intervention.

Conclusion

The findings of this study suggest that MPST could be beneficial in reducing depressive symptoms and enhancing positive coping and self-efficacy levels in older adults in nursing homes.

Efficacy of psychotherapy in subthreshold depression patients: A protocol for an overview of systematic reviews and meta-analyses

Background

Subthreshold depression is a risk factor for major depression. Psychotherapy is a kind of intervention for subthreshold depression. There have been many systematic reviews synthesized the evidence for its effectiveness toward subthreshold depression. However, there is currently no overview of these systematic reviews.

Objective

To undertake an overview of meta-analyses and systematic reviews to identify the efficacy of psychotherapy in subthreshold depression patients.

Methods

We will search several databases such as PubMed, Embase, the Cochrane Library, Web of Science, PsycINFO, CNKI, WanFang and VIP database, for systematic reviews and meta-analyses on psychotherapy in subthreshold depression patients. The search timeline will be from inception up to August 2022. Two researchers will screen related studies back-to-back. We will include studies that evaluate the efficacy of psychotherapy in subthreshold depression patients. We will evaluate the methodological quality, the reporting quality and the quality of evidence for outcomes by AMSTAR-2, the PRISMA 2020 checklist and the GRADE grading system. We will present the results of the overview in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The anticipated start and completion dates for this overview are 1 August 2022 and 30 December 2022, respectively.

Results

From this study, we will evaluate the methodological quality and the level of evidence of the included systematic reviews and meta-analyses, and evaluate the efficacy of psychotherapy in patients with subthreshold depression.

Implications

We will ascertain the efficacy of psychotherapy in subthreshold depression patients, to provide evidence to guide the treatment of subthreshold depression in the future.

Cost-effectiveness of Tele-delivered behavioral activation by Lay counselors for homebound older adults with depression

BACKGROUND

Low-income homebound older adults have limited access to psychosocial treatments because of their homebound state and geriatric mental health workforce shortages. Little is known about cost effectiveness of lay-counselor-delivered, videoconferenced, short-term behavioral activation on this study population. The objective of this study was to assess the cost-effectiveness of lay-counselor-delivered, videoconferenced, short-term behavioral activation (Tele-BA) compared to clinician-delivered, videoconferenced problem-solving therapy (Tele-PST) and telephone support calls (attention control; AC) for low-income homebound older adults.

METHODS

We performed a cost-effectiveness analysis based on data from a recently completed, 3-group (Tele-BA, Tele-PST, and AC) randomized controlled trial with 277 participants aged 50+. We measured total costs of (1) intervention and (2) outpatient care, ED visits, and inpatient care using the Cornell Services Index. The effectiveness outcome was quality-adjusted life-years (QALY). We used EuroQol's EQ-5D-5L to assess each participant's health-related quality of life (HRQoL) at baseline and at 12, 24, and 36 weeks. The end-point measure of cost-effectiveness was the incremental cost-effectiveness ratio (ICER) of (1) Tele-BA versus AC, (2) Tele-PST versus AC, and (3) Tele-BA versus Tele-PST.

RESULTS

Relative to AC, both Tele-BA and Tele-PST are cost-saving treatment options. The ICERs for both Tele-BA and Tele-PST were well below $50,000, the lower-bound threshold for cost-effectiveness. Relative to AC, both Tele-PST, Tele-BA are cost-saving treatment options (i.e. lower costs and more QALYs).

CONCLUSION

Costs of tele- and lay-counselor-delivered depression treatment are modest and cost effective relative to providing telephone support. Though our results show that Tele-BA may not be cost effective relative to Tele-PST, a clinician-delivered psychotherapy, when a low bound ICER threshold of $50,000 would be used, lay counselors can fill the professional geriatric mental health workforce shortage gap and Tele-BA by lay counselors can improve homebound older adults' access to evidence-and skills-based, cost effective depression care.

Effectiveness of Case Management with Problem-Solving Therapy for Rural Older Adults with Depression

OBJECTIVE

To evaluate the effect of case management with problem solving therapy (CM-PST) on depression and disability among rural older adults and compare its effect with outcomes derived from a previous, but similar study among 84 urban older adults.

METHODS

This study examined the comparative effectiveness of a CM-PST intervention for older adults with depression and unmet needs across rural and urban settings. Participants received 12 one-hour sessions of CM-PST with a master's-level clinician. A total of 56 rural and 84 urban adults aged 60 and older experiencing mild to moderate depression received services in their homes.

RESULTS

The rural CM-PST intervention resulted in significantly reduced depression (reduction of 13.9 points, 95% CI 12.2 to 15.7, t(422)= 15.35, p<0.0001) and disability by week 12 (reduction of 6.7 points, 95% CI 4.8 to 8.5, t(425)= 7.01, p<0.0001). Reductions in depression and disability were sustained through week 24. The reductions in depression (F=3.98 df=4,388. p=0.0035) and disability (F=2.71, df=4,381, p=0.03) found in the rural sample were comparable to, or better than, those found in the urban sample. Improvements in unmet need and resilience predicted lower depression scores at 12 weeks, while improvements in unmet need and hopelessness predicted improvements in disability. No moderators of depression were identified, but baseline values of self-efficacy, resilience, and hopelessness moderated disability.

CONCLUSIONS

CM-PST was as effective at reducing depression and disability among rural older adults as it was for urban older adults. Home-delivered CM-PST can be successfully adapted to meet the specific needs of rural seniors using resources often available in rural communities.

Implementation of the Community Assets Supporting Transitions (CAST) transitional care intervention for older adults with multimorbidity and depressive symptoms: A qualitative descriptive study

Background

Older adults with multimorbidity experience frequent care transitions, particularly from hospital to home, which are often poorly coordinated and fragmented. We conducted a pragmatic randomized controlled trial to test the implementation and effectiveness of Community Assets Supporting Transitions (CAST), an evidence-informed nurse-led intervention to support older adults with multimorbidity and depressive symptoms with the aim of improving health outcomes and enhancing transitions from hospital to home. This trial was conducted in three sites, representing suburban/rural and urban communities, within two health regions in Ontario, Canada.

Purpose

This paper reports on facilitators and barriers to implementing CAST.

Methods

Data collection and analysis were guided by the Consolidated Framework for Implementation Research framework. Data were collected through study documents and individual and group interviews conducted with Care Transition Coordinators and members from local Community Advisory Boards. Study documents included minutes of meetings with research team members, study partners, Community Advisory Boards, and Care Transition Coordinators. Data were analyzed using content analysis.

Findings

Intervention implementation was facilitated by: (a) engaging the community to gain buy-in and adapt CAST to the local community contest; (b) planning, training, and research meetings; (c) facilitating engagement, building relationships, and collaborating with local partners; (d) ensuring availability of support and resources for Care Transition Coordinators; and (e) tailoring of the intervention to individual client (i.e., older adult) needs and preferences. Implementation barriers included: (a) difficulties recruiting and retaining intervention staff; (b) difficulties engaging older adults in the intervention; (c) balancing tailoring the intervention with delivering the core intervention components; and (c) Care Transition Coordinators’ challenges in engaging providers within clients’ circles of care.

Conclusion

This research enhances our understanding of the importance of considering intervention characteristics, the context within which the intervention is being implemented, and the processes required for implementing transitional care intervention for complex older adults.

Effectiveness of late-life depression interventions on functional limitations: A systematic review

Depression is one of the most prevalent mental disorders in older adults and leads to considerable decreases in health, well-being, and impaired functioning. Intervention studies have focused on the effects on symptomatic recovery, and most do not include functional recovery as an outcome. Reduction of functional limitations as a treatment goal in old-age psychiatry aligns with the values of older persons. The objective of this review was therefore to evaluate the effectiveness of late-life depression interventions on functional limitations. This systematic review identified 15 randomized controlled trials in which the effectiveness of different interventions on functional limitations was evaluated in patients with late-life depression. The interventions were categorized into four categories: psychological interventions, drug treatment, physical exercise, and collaborative care. Multicomponent and collaborative-care interventions appear to be the most promising for improvement of functional limitations, particularly in primary care and community-dwelling populations of older persons with symptoms of depression. There is, however, a lack of evidence regarding studies in specialized mental health care.

Cognitive outcomes are differentially associated with depression severity trajectories during psychotherapy treatment for late life major depressive disorder

OBJECTIVES

Late Life Depression (LLD) is associated with persistent cognitive dysfunction even after depression symptoms improve. The present study was designed to examine cognitive outcomes associated with the pattern of depression severity change during psychotherapy intervention for LLD.

METHODS

96 community-dwelling adults ages 65-91 with major depressive disorder completed 12 sessions of Problem-Solving Therapy at the University of California, San Francisco. Nonlinear trajectories of depression severity ratings using the Hamilton Depression Rating Scale were computed from multiple time points collected throughout the weekly psychotherapy intervention. Performance on measures of cognition (information processing speed, executive functioning, verbal learning, memory) was assessed at baseline and post-treatment. Linear mixed-effects models examined associations between nonlinear depression severity trajectories and post-treatment change in cognitive performance.

RESULTS

Broadly, different patterns of depression change during treatment were associated with improved cognition post-treatment. Greater and more consistent interval improvements in depression ratings were differentially associated with improvements in aspects of verbal learning, memory, and executive function post-treatment, while no associations were found with information processing speed.

CONCLUSIONS

The heterogeneity of depression trajectories associated with improved cognitive outcomes suggests that the temporal pattern of depression response may impact specific cognitive processes distinctly. Results suggest that use of nonlinear depression severity trajectories may help to elucidate complex associations between the time course of depression response and cognitive outcomes of psychotherapy in LLD. These findings have important implications for identifying treatment targets to enhance clinical and cognitive outcomes of psychotherapy in LLD.

Virtual Intervention for Caregivers of Persons With Lewy Body Dementia: Pilot Quasi-Experimental Single-Arm Study

BACKGROUND

Compared to other types of dementia, family caregivers of people with Lewy body dementia (LBD) report higher stress levels and more severe depressive symptoms. Although several digital support interventions for caregivers of persons with dementia exist, few target LBD specifically or leverage a fully remote and asynchronous approach suitable for pandemic circumstances.

OBJECTIVE

We performed a pilot evaluation of a digital intervention designed to help caregivers of people with LBD address challenges they have experienced, with the end goal of reducing psychological distress in this population.

METHODS

We recruited 15 family caregivers of people with LBD to participate in the quasi-experimental, single-arm, mixed methods study titled Virtual Online Communities for Aging Life Experience-Lewy Body Dementia (VOCALE-LBD). The study offers an 8-week web-based intervention that uses a digital discussion platform and involves moderation, peer-to-peer support, didactic training, and problem-solving skill enactment.

RESULTS

Participants' baseline characteristics were the following: mean age 66 (SD 8) years; 14 of 15 (93%) of them were female; all (15/15, 100%) were White; and 8 (53%) of them had at least a postgraduate degree. Throughout the intervention, participants engaged in weekly web-based discussions, generating a total of 434 posts (average 4 posts per week). Attrition was 20% (3/15). Upon study exit, participants showed the following average improvements: 3.0 (SD 6.0) in depression, 8.3 (SD 16.7) in burden, 2.9 (SD 6.8) in stress, and 0.3 (SD 0.8) in loneliness. When looking at the proportion of participants with clinically significant improvement versus those with a worsening of ≥0.5 SD for each outcome, we observed net improvements of 50% (6/12), 33% (4/12), 25% (3/12), and 25% (3/12) in depression, loneliness, burden, and stress, respectively. In terms of the benefits of participation, participants reported that participation helped them "a great deal" to (1) improve their understanding of LBD (9/12, 75%), (2) gain confidence in dealing with difficult behaviors of the care recipient (6/12, 50%), and (3) improve in one's abilities to provide care to the care recipient (4/12, 33%).

CONCLUSIONS

The study generated promising feasibility and preliminary efficacy data for a low-cost, web-based intervention designed for caregivers of persons with LBD. Though the study was not powered for significance, we observed nominal average and net improvements in important psychological outcomes. Moreover, many caregivers reported that study participation helped them better understand the disease, feel more confident in dealing with difficult behaviors of the care recipient, and improve their ability to care for the care recipient. If validated in future studies, the intervention could be an accessible, on-demand resource for caregivers, enabling them to engage in moderated remote discussions with peers at their own convenience in terms of location, time of the day, and frequency.

Association of COVID-19 impact with outcomes of an integrated obesity and depression intervention: Posthoc analysis of an RCT

OBJECTIVE

To examine the association between COVID-19 impact and clinical outcomes of an integrated collaborative care intervention for adults with obesity and comorbid depression.

METHODS

Latent class analysis identified clusters of self-reported COVID-19 impact. Cluster characteristics were examined using Fishers' least significant difference method and canonical discriminant analysis. Intervention vs. usual care effects on primary (body mass index [BMI], depressive symptoms) and secondary (anxiety symptoms and other psychosocial) outcomes stratified by cluster were examined using linear mixed models.

RESULTS

Three clusters were identified: mental health and sleep impact (cluster 1, n = 37), economic impact (cluster 2, n = 18), and less overall impact (cluster 3, n = 20). Clusters differed in age, income, diet, and baseline coping skills. The intervention led to improvements across several health outcomes compared with usual care, with medium to large effects on functional impairments (standardized mean difference, -0.7 [95% CI: -1.3, -0.1]) in cluster 1, depressive symptoms (-1.1 [95% CI: -2.0, -0.1]) and obesity-related problems (-1.6 [95% CI: -2.8, -0.4]) in cluster 2, and anxiety (-1.1 [95% CI: -1.9, -0.3]) in cluster 3.

CONCLUSIONS

People with obesity and comorbid depression may have varied intervention responses based on COVID-19 impact. Interventions tailored to specific COVID-19 impact clusters may restore post-pandemic health.

Psychological treatments for depression and anxiety in dementia and mild cognitive impairment

BACKGROUND

Experiencing anxiety and depression is very common in people living with dementia and mild cognitive impairment (MCI). There is uncertainty about the best treatment approach. Drug treatments may be ineffective and associated with adverse effects. Guidelines recommend psychological treatments. In this updated systematic review, we investigated the effectiveness of different psychological treatment approaches.

OBJECTIVES

Primary objective To assess the clinical effectiveness of psychological interventions in reducing depression and anxiety in people with dementia or MCI. Secondary objectives To determine whether psychological interventions improve individuals' quality of life, cognition, activities of daily living (ADL), and reduce behavioural and psychological symptoms of dementia, and whether they improve caregiver quality of life or reduce caregiver burden.

SEARCH METHODS

We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's register, MEDLINE, Embase, four other databases, and three trials registers on 18 February 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared a psychological intervention for depression or anxiety with treatment as usual (TAU) or another control intervention in people with dementia or MCI.

DATA COLLECTION AND ANALYSIS

A minimum of two authors worked independently to select trials, extract data, and assess studies for risk of bias. We classified the included psychological interventions as cognitive behavioural therapies (cognitive behavioural therapy (CBT), behavioural activation (BA), problem-solving therapy (PST)); 'third-wave' therapies (such as mindfulness-based cognitive therapy (MBCT)); supportive and counselling therapies; and interpersonal therapies. We compared each class of intervention with control. We expressed treatment effects as standardised mean differences or risk ratios. Where possible, we pooled data using a fixed-effects model. We used GRADE methods to assess the certainty of the evidence behind each result.

MAIN RESULTS

We included 29 studies with 2599 participants. They were all published between 1997 and 2020. There were 15 trials of cognitive behavioural therapies (4 CBT, 8 BA, 3 PST), 11 trials of supportive and counselling therapies, three trials of MBCT, and one of interpersonal therapy. The comparison groups received either usual care, attention-control education, or enhanced usual care incorporating an active control condition that was not a specific psychological treatment. There were 24 trials of people with a diagnosis of dementia, and five trials of people with MCI. Most studies were conducted in community settings. We considered none of the studies to be at low risk of bias in all domains.  Cognitive behavioural therapies (CBT, BA, PST) Cognitive behavioural therapies are probably slightly better than treatment as usual or active control conditions for reducing depressive symptoms (standardised mean difference (SMD) -0.23, 95% CI -0.37 to -0.10; 13 trials, 893 participants; moderate-certainty evidence). They may also increase rates of depression remission at the end of treatment (risk ratio (RR) 1.84, 95% CI 1.18 to 2.88; 2 studies, with one study contributing 2 independent comparisons, 146 participants; low-certainty evidence). We were very uncertain about the effect of cognitive behavioural therapies on anxiety at the end of treatment (SMD -0.03, 95% CI -0.36 to 0.30; 3 trials, 143 participants; very low-certainty evidence). Cognitive behavioural therapies probably improve patient quality of life (SMD 0.31, 95% CI 0.13 to 0.50; 7 trials, 459 participants; moderate-certainty evidence) and activities of daily living at end of treatment compared to treatment as usual or active control (SMD -0.25, 95% CI -0.40 to -0.09; 7 trials, 680 participants; moderate-certainty evidence). Supportive and counselling interventions Meta-analysis showed that supportive and counselling interventions may have little or no effect on depressive symptoms in people with dementia compared to usual care at end of treatment (SMD -0.05, 95% CI -0.18 to 0.07; 9 trials, 994 participants; low-certainty evidence). We were very uncertain about the effects of these treatments on anxiety, which was assessed only in one small pilot study. Other interventions There were very few data and very low-certainty evidence on MBCT and interpersonal therapy, so we were unable to draw any conclusions about the effectiveness of these interventions.

AUTHORS' CONCLUSIONS

CBT-based treatments added to usual care probably slightly reduce symptoms of depression for people with dementia and MCI and may increase rates of remission of depression. There may be important effect modifiers (degree of baseline depression, cognitive diagnosis, or content of the intervention). CBT-based treatments probably also have a small positive effect on quality of life and activities of daily living. Supportive and counselling interventions may not improve symptoms of depression in people with dementia. Effects of both types of treatment on anxiety symptoms are very uncertain. We are also uncertain about the effects of other types of psychological treatments, and about persistence of effects over time. To inform clinical guidelines, future studies should assess detailed components of these interventions and their implementation in different patient populations and in different settings.

Problem Solving Training for Veterans with Complex Comorbidities: Treatment Delivery Adaptations during COVID-19

OBJECTIVES

To summarize adaptations due to COVID-19 for VA Problem Solving Training (PST) for clinicians serving medically complex patients and to compare patient mental health outcomes in the year before (2019) and during COVID-19 (2020).

METHODS

Clinicians attended a multi-day workshop and up to 6 months of small-group consultation for two training cases. In 2019 and 2020, 122 Veteran patients completed baseline and posttreatment measures of depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder-7 item), and negative problem-solving beliefs (Negative Problem Orientation Questionnaire). Qualitative data were collected on clinician's pandemic-related treatment implementation challenges.

RESULTS

Program adaptations during COVID-19 addressed challenges due to delivering treatment by telephone, video, or in person; Veteran patient recruitment barriers; and privacy issues for telephone and video. Veterans in both pre-pandemic and COVID-19 cohorts had significant improvements in depression, anxiety, and negative problem-solving beliefs, with no significant differences in the amount of improvement between the two cohorts.

CONCLUSIONS

Flexibilities afforded to clinicians delivering the PST training program during the pandemic addressed key obstacles and barriers to recruitment, and implementation did not diminish the effectiveness of the intervention.

CLINICAL IMPLICATIONS

Findings support continued implementation of the PST training program with added flexibility to treatment delivery beyond the pandemic.

PRN Medicines Management for Older People with Long-Term Mental Health Disorders in Home Care

Older people with long-term mental health conditions who receive care in their own home are vulnerable to the inappropriate use of medications and polypharmacy given their underlying health conditions and comorbidities. Inappropriate use of pro re nata (PRN) medications in these older people can enhance their suffering and have negative consequences for their quality of life and well-being, leading to readmission to healthcare settings and the increased cost of health care. This narrative review on published international literature aims at improving our understanding of medicines management in home care and how to improve PRN medication use among older people with long-term health conditions in their own home. Accordingly, the improvement of PRN medicines management for these older people requires the development of an individualised care plan considering ‘reduction of older people’s dependence on PRN medications’, ‘empowerment of family caregivers’, and ‘support by healthcare professionals.’ PRN medication use should be reduced through deprescription and discontinuation strategies. Also, older people and their family caregivers should be encouraged to prioritize the use of non-pharmacologic methods to relieve physical and psychological problems. Besides the empowerment of family caregivers through role development, education and training about PRN medications, and involvement in decision-making, they need support by the multidisciplinary network in terms of supervision, monitoring, and home visits.

Problem-solving therapy for major depressive disorders in older adults: an updated systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Major depressive disorder is a global public health problem among older adults. Many studies show that problem-solving therapy (PST) is a cognitive behavioral approach that can effectively treat late-life depression.

AIM

To summarize and assess the effects of PST on major depressive disorders in older adults.

METHODS

We searched the PubMed, Web of Science, Cochrane Library, EMBASE, MEDLINE, UpToDate, and PsycINFO databases and three Chinese databases (CNKI, CBM, and Wan Fang Data) to identify articles written in English or Chinese that were published until Feb 1, 2020. Randomized controlled trials were included if they evaluated the impact of PST on major depression disorder (MDD) in older adults. Two authors of this review independently selected the studies, assessed the risk of bias, and extracted the data from all the included studies. We calculated the standard mean differences (SMDs) with 95% confidence intervals (CIs) for continuous data. We assessed heterogeneity using the I² statistic.

RESULTS

Ten studies with a total of 892 participants met the inclusion criteria. Subgroup analyses and quality ratings were performed. After problem-solving therapy, the depression scores in the intervention group were significantly lower than those in the control group (SMD = - 1.06, 95% CI - 1.52 to - 0.61, p < 0.05; I² = 88.4%).

DISCUSSION

Compared with waitlist (WL), PST has a significant effect on elderly patients with depression, but we cannot rank the therapeutic effects of all the treatment methods used for MDD.

CONCLUSIONS

Our meta-analysis and systematic review suggest that problem-solving therapy may be an effective approach to improve major depressive disorders in older adults.

Non-pharmacological interventions for older adults with depressive symptoms: a network meta-analysis of 35 randomized controlled trials

Objective: To assess the effectiveness of non-pharmacological interventions for seniors with depressive symptoms.Methods: A comprehensive literature search was performed. We conducted network meta-analysis in two ways, intervention classes (psychosocial, psychotherapy, physical activity, combined, treatment as usual) and individual intervention (11 categories). Whenever included studies used different scales, the different instruments were converted to the units of the scale most frequently used (the Geriatric Depression Scale), such that the effect size was reported as a mean difference (MD) with 95% confidence interval (CI). The risk of bias of RCTs included in this review was assessed according to the Cochrane Handbook. Bayesian NMA was conducted using R-3.4.0 software.Results: A total of 35 RCTs with 3,797 enrolled patients were included. Compared to conventional treatment, physical activity and psychotherapy resulted in significant improvements in depressive symptoms (MD: 2.25, 95%CrI: 0.99-3.56; SUCRA = 86.07%; MD: 1.75, 95% CrI: 0.90-2.64; SUCRA = 66.44%, respectively). Similar results were obtained for music (MD: 2.6; 95% CrI: 0.84-4.35;SUCRA = 80.53%), life review (MD:1.92; 95% CrI:0.71-3.14; SUCRA = 65.62%), cognitive behavioral therapy (MD: 1.27; 95% CrI: 0.23-2.38; SUCRA = 45.4%), aerobic (MD: 1.84; 95% CrI: 0.39-3.36; SUCRA = 63%) and resistance training (MD: 1.72; 95% CrI: 0.06-3.42; SUCRA = 59.24%). Network meta-regression showed that there were no statistically significant subgroup effects.Conclusions: Physical activity and psychotherapy demonstrated statistically significant superiority over conventional treatment. Music and life review therapy proved the most promising individual interventions. However, conclusions are limited by the lack of sufficient sample size and consensus regarding intervention categories and so an adequately powered study is necessary to consolidate these findings.

Interventions to prevent elder abuse in the community: a mixed-methods systematic review

OBJECTIVE

To identify the interventions proposed in the literature aimed at preventing elder abuse among community-residing elders.

METHOD

This was a mixed-methods systematic review that followed the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols checklist. The protocol of this systematic review was registered in the International Prospective Register of Systematic Reviews. We included studies published between January 2004 and December 2019 in the databases: LILACS, IBECS, CUMED, CINAHL, MEDLINE and SciELO. The methodological quality of each study included was performed using the Mixed Methods Appraisal Tool.

RESULTS

Seven studies formed the final sample. Two groups emerged after the analyses: the primary level intervention group, which used health education and coexisting elder abuse groups; and the secondary intervention level, focused mostly on the mental health care of victims of elder abuse.

CONCLUSION

There is still a shortage of intervention studies to prevent elder abuse. All the studies selected had a positive outcome, and all interventions can be implemented in nursing care practice.

Adapting and Optimizing Problem Adaptation Therapy (PATH) for People With Mild-Moderate Dementia and Depression

OBJECTIVE

To adapt and optimize problem adaptation therapy for depression in dementia by grounding it in the lives of people with dementia, caregivers and clinicians.

METHODS

A person-centered qualitative approach was taken to elicit the unique cognitive, psychological and social needs of people with dementia relevant to the adaptation of the intervention. A two-stage design was used: the first involved interviews and focus groups to identify priorities and concerns surrounding depression in dementia, the second trialling of the adapted intervention.

PARTICIPANTS

Ten people with dementia and nine caregivers participated in individual interviews, 35 healthcare practitioners and clinical academics with experience of working with dementia participated in focus groups.

RESULTS

The findings highlight the importance of addressing key themes that typified the experience of depression among people with dementia including: a profound sense of isolation and role loss, the feeling of being both a burden and poorly understood, polarized thinking, interpersonal tensions, diverging views among carers and people with dementia about their capabilities, and changeability in cognitive ability and mood. These themes were used to inform adaptation of the intervention manual, ensuring that its content and delivery addressed the concerns of both people with depression and dementia and those who support them.

CONCLUSION

Implications for PATH included a focus on facilitating open communication, supporting the continuation of valued roles, and improving confidence.

Brief problem-solving therapy for antenatal depressive symptoms in primary care in rural Ethiopia: protocol for a randomised, controlled feasibility trial

BACKGROUND

Despite a high prevalence of antenatal depression in low- and middle-income countries, there is very little evidence for contextually adapted psychological interventions delivered in rural African settings. The aims of this study are (1) to examine the feasibility of procedures for a future fully powered efficacy trial of contextually adapted brief problem solving therapy (PST) for antenatal depression in rural Ethiopia, and (2) to investigate the acceptability, fidelity and feasibility of delivery of PST in routine antenatal care.

METHODS

Design: A randomised, controlled, feasibility trial and mixed method process evaluation.

PARTICIPANTS

Consecutive women attending antenatal clinics in two primary care facilities in rural Ethiopian districts. Eligibility criteria: (1) disabling levels of depressive symptoms (Patient Health Questionnaire (PHQ-9) score of five or more and positive for the 10th disability item); (2) gestational age 12-34 weeks; (3) aged 16 years and above; (4) planning to live in the study area for at least 6 months; (5) no severe medical or psychiatric conditions.

INTERVENTION

Four sessions of adapted PST delivered by trained and supervised antenatal care staff over a maximum period of eight weeks.

CONTROL

enhanced usual care (EUC).

SAMPLE SIZE

n = 50. Randomisation: individual randomisation stratified by intimate partner violence (IPV). Allocation: central phone allocation. Outcome assessors and statistician masked to allocation status. Primary feasibility trial outcome: dropout rate. Primary future efficacy trial outcome: change in PHQ-9 score, assessed 9 weeks after recruitment.

SECONDARY OUTCOMES

anxiety symptoms, trauma symptoms, intimate partner violence, disability, healthcare costs at 9 weeks; postnatal outcomes (perinatal and neonatal complications, onset of breast feeding, child health) assessed 4-6 weeks postnatal. Other trial feasibility indicators: recruitment, number and duration of sessions attended. Audio-recording of randomly selected sessions and in-depth interviews with purposively selected participants, healthcare providers and supervisors will be analysed thematically to explore the acceptability and feasibility of the trial procedures and fidelity of the delivery of PST.

DISCUSSION

The findings of the study will be used to inform the design of a fully powered efficacy trial of brief PST for antenatal depression in routine care in rural Ethiopia.

TRIAL REGISTRATION

The protocol was registered in the Pan-African clinical trials registry, (PACTR): registration number: PACTR202008712234907 on 18/08/2020; URL: https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=9578 .

Promoting Problem Solving About Health Management: A Mixed-Methods Pilot Evaluation of a Digital Health Intervention for Older Adults With Pre-Frailty and Frailty

Background: There is a need for interventions to promote health management of older adults with pre-frailty and frailty. Technology poses promising solutions, but questions exist about effective delivery. Objectives: We present the results of a mixed-methods pilot evaluation of Virtual Online Communities for Older Adults (VOCALE), an 8-week intervention conducted in the northwestern United States, in which participants shared health-related experiences and applied problem solving skills in a Facebook group. Methods: We performed a mixed-methods process evaluation, integrating quantitative and qualitative data, to characterize the intervention and its effects. We focus on four areas: health-related measures (health literacy and self-efficacy), participation, problem solving skills enacted, and subjective feedback. Results: Eight older adults with pre-frailty and frailty (age = 82.7 ± 6.6 years) completed the study. There was an upward trend in health literacy and health self-efficacy post-intervention. Participants posted at least two times per week. Content analysis of 210 posts showed participants were able to apply the problem solving skills taught, and exit interviews showed participants' increased awareness of the need to manage health, and enjoyment in learning about others. Conclusion: This mixed-methods evaluation provides insight into feasibility and design considerations for online interventions to promote health management among vulnerable older adults.

Supporting frail older people with depression and anxiety: a qualitative study

OBJECTIVES

Depression and anxiety are common in later life, particularly when people are frail. This leads to reduced quality of life, faster decline in physical health and increased health/social care use. Available treatments are commonly not tailored to people with frailty. We explored frail older peoples' experiences of depression and/or anxiety and how services could be adapted to their needs.

METHODS

Semi-structured interviews with 28 older people in the UK purposively sampled for practice location and severity of frailty and anxiety/depression. We asked about symptoms, interactions with physical health, help-seeking, treatments and what might help in future. We audio-recorded and transcribed interviews, using thematic analysis to inductively derive themes.

RESULTS

Frail older people had low expectations of their wellbeing at this point in life due to multiple physical health issues and so anxiety and mild depressive symptoms were normalised. There was a particular reluctance and uncertainty regarding help-seeking for anxiety. Treatments were considered appropriate where they aligned with coping skills developed over their lifetime, and facilitated independence and problem-solving skills. Most older people felt their knowledge of mental health was limited and relied upon information about and endorsement of therapies from an expert. This was usually their GP, but access was often problematic. Online methods of accessing information and therapies were not popular.

CONCLUSION

Mental health support for frail older people needs to address late-life anxieties as well as depression, account for physical health issues, align with older people's need for independence and facilitate coping skills.

Improvements in Functional Disability After Psychotherapy for Depression Are Associated With Reduced Suicide Ideation Among Older Adults

OBJECTIVE

To evaluate the association between changes in functional disability and suicide ideation among older adults following psychotherapy for depression.

METHODS

Sixty-five participants (65-91 years old, 72% White, and 66% female) with depression completed 12 sessions of problem solving therapy (PST) and completed measures of disability (WHO Disability Assessment Schedule 2.0) and suicide ideation (Geriatric Suicide Ideation Scale [GSIS]) at baseline and post-treatment.

RESULTS

Hierarchical linear regressions found that reductions in functional disability were associated with overall reductions in suicide ideation on the GSIS (F[4,60] = 4.06, p < 0.01), particularly with the Loss of Worth GSIS subscale (F[4,60] = 7.86, p < 0.001, ΔR² = 0.140).

CONCLUSIONS

Results suggest decreased functional disability following depression treatment is associated with decreased suicide ideation, especially thoughts regarding loss of worth. These results highlight the potential for treatments that reduce functional disability (e.g., PST) to reduce risk of suicide among older adults.

Sadness and Worry in Older Adults: Differentiating Psychiatric Illness from Normative Distress

Older adults experience greater emotional well-being in late life. However, older adults may be vulnerable to certain physiologic risk factors, including less physiologic resilience to prolonged stress. Depression and anxiety can be difficult to diagnose in late life owing to differences in self-reported symptoms from younger adults and unclear distinctions between normative and non-normative emotional experiences. We discuss age differences in the presentations of depression and anxiety, and normative and non-normative late life developmental trajectories around bereavement and grief, social isolation and loneliness, and thoughts of death and suicide. We provide recommendations for clinicians for assessing and diagnosing older adults.

Psychotherapy for Depression Across Different Age Groups: A Systematic Review and Meta-analysis

IMPORTANCE

It is not clear whether psychotherapies for depression have comparable effects across the life span. Finding out is important from a clinical and scientific perspective.

OBJECTIVE

To compare the effects of psychotherapies for depression between different age groups.

DATA SOURCES

Four major bibliographic databases (PubMed, PsychINFO, Embase, and Cochrane) were searched for trials comparing psychotherapy with control conditions up to January 2019.

STUDY SELECTION

Randomized trials comparing psychotherapies for depression with control conditions in all age groups were included.

DATA EXTRACTION AND SYNTHESIS

Effect sizes (Hedges g) were calculated for all comparisons and pooled with random-effects models. Differences in effects between age groups were examined with mixed-effects subgroup analyses and in meta-regression analyses.

MAIN OUTCOMES AND MEASURES

Depressive symptoms were the primary outcome.

RESULTS

After removing duplicates, 16 756 records were screened and 2608 full-text articles were screened. Of these, 366 trials (36 702 patients) with 453 comparisons between a therapy and a control condition were included in the qualitative analysis, including 13 (3.6%) in children (13 years and younger), 24 (6.6%) in adolescents (≥13 to 18 years), 19 (5.2%) in young adults (≥18 to 24 years), 242 (66.1%) in middle-aged adults (≥24 to 55 years), 58 (15.8%) in older adults (≥55 to 75 years), and 10 (2.7%) in older old adults (75 years and older). The overall effect size of all comparisons across all age groups was g = 0.75 (95% CI, 0.67-0.82), with very high heterogeneity (I2 = 80%; 95% CI: 78-82). Mean effect sizes for depressive symptoms in children (g = 0.35; 95% CI, 0.15-0.55) and adolescents (g = 0.55; 95% CI, 0.34-0.75) were significantly lower than those in middle-aged adults (g = 0.77; 95% CI, 0.67-0.87). The effect sizes in young adults (g = 0.98; 95% CI, 0.79-1.16) were significantly larger than those in middle-aged adults. No significant difference was found between older adults (g = 0.66; 95% CI, 0.51-0.82) and those in older old adults (g = 0.97; 95% CI, 0.42-1.52). The outcomes should be considered with caution because of the suboptimal quality of most of the studies and the high levels of heterogeneity. However, most primary findings proved robust across sensitivity analyses, addressing risk of bias, target populations included, type of therapy, diagnosis of mood disorder, and method of data analysis.

CONCLUSIONS AND RELEVANCE

Trials included in this meta-analysis reported effect sizes of psychotherapies that were smaller in children than in adults, probably also smaller in adolescents, that the effects may be somewhat larger in young adults, and without meaningful differences between middle-aged adults, older adults, and older old adults.

Depression in the Elderly. Consensus Statement of the Spanish Psychogeriatric Association

INTRODUCTION

Present knowledge about depression in the elderly is still scarce and often controversial, despite its high frequency and impact. This article reports the results and most relevant conclusions of a Delphi-based consensus on geriatric depression promoted by the Spanish Psychogeriatric Association.

METHODS

A 78-item questionnaire was developed by 7 highly specialized geriatric psychiatrists and was evaluated using the Modified Delphi technique in two rounds answered by 35 psychiatrists with an extensive expertise in geriatric depression. The topics and number of questions (in brackets) covered were: concepts, clinical aspects, and risk factors (12); screening and diagnosis (7); psychotic depression (17); depression and dementia (5); antidepressant drug treatment (18); non-pharmacological biological treatments (5); psychotherapeutic treatments (4); comorbidity and preventive aspects (6); professional training needed (4). In addition, the expert panel's opinion on the antidepressants of choice in 21 common comorbid conditions and on different strategies to approach treatment-resistant cases in terms of both efficacy and safety was assessed.

RESULTS

After the two rounds of the Delphi process, consensus was reached for 59 (75.6%) of the 78 items. Detailed recommendations are included in the text. Considering pharmacological treatments, agomelatine was the most widely mentioned drug to be recommended in terms of safety in comorbid conditions. Desvenlafaxine, sertraline, and vortioxetine, were the most frequently recommended antidepressants in comorbid conditions in general. Combining parameters of efficacy and safety, experts recommended the following steps to address cases of treatment resistance: 1. Escalation to the maximum tolerated dose; 2. Change of antidepressant; 3. Combination with another antidepressant; 4. Potentiation with an antipsychotic or with lamotrigine; 5. Potentiation with lithium; 6. Potentiation with dopamine agonists or methylphenidate.

DISCUSSION AND CONCLUSIONS

Consensus was reached for a high number of items as well as for the management of depression in the context of comorbid conditions and in resistant cases. In the current absence of sufficient evidence-based information, our results can be used to inform medical doctors about clinical recommendations that might reduce uncertainty in the diagnosis and treatment of elderly patients with depressive disorders.

Interpersonal Psychotherapy for Late-life Depression and its Potential Application in China

Interpersonal psychotherapy (IPT) is a time-limited, structured, interpersonally oriented psychotherapy, with demonstrated efficacy for the treatment of major depression across the lifespan. IPT uses a medical model of illness and links depressed mood to four research-informed interpersonal problem areas: complicated grief, role transitions, role disputes, and interpersonal deficits/sensitivity. The IPT model of vulnerability to depression nicely dovetails with interpersonal issues that are faced by older adults, and this article focuses on the application of IPT for late-life depression in China. The group format of IPT may be a practical and efficient method of improving access to an established depression-focused treatment for China's rapidly aging population and has the advantage of providing important social support for patients who feel lonely, isolated, and stigmatized. Short-term interventions like IPT are more cost-effective from a public health perspective and can easily be delivered in primary care facilities, where many elderly patients receive care. IPT is effective in different cultures, and possible cultural adaptations of IPT for older adults in China are discussed herein.

Non-pharmacological interventions for depression/anxiety in older adults with physical comorbidities affecting functioning: systematic review and meta-analysis

OBJECTIVE

To review the effectiveness of non-pharmacological interventions in older adults with depression or anxiety and comorbidities affecting functioning.

DESIGN

Systematic review and meta-analysis of randomized controlled trials, including searches of 10 databases (inception-Jul 2017).

SETTING

Home/community.

PARTICIPANTS

People aged 60 and over experiencing functional difficulties from physical or cognitive comorbidities and have symptoms or a diagnosis of depression and/or anxiety.

INTERVENTIONS

Non-pharmacological interventions targeted at depression/anxiety.

MEASUREMENTS

We extracted outcome data on depressive symptoms, quality of life, functioning, and service use. We used random effects meta-analysis to pool study data where possible. Two authors assessed the risk of bias using the Cochrane Risk of Bias tool.

RESULTS

We identified 14 eligible trials including 2099 randomized participants and two subgroup analyses. Problem-solving therapy (PST) reduced short-term clinician-rated depressive symptoms (n = 5 trials, mean difference in Hamilton Depression Rating Scale score -4.94 [95% CI -7.90 to -1.98]) but not remission, with limited evidence for effects on functioning and quality of life. There was limited high-quality evidence for other intervention types. Collaborative care did not appear to affect depressive symptoms, functioning, or quality of life; and had mixed evidence for effects upon remission. No intervention consistently affected service use, but trials were limited by small sample sizes and short follow-up periods. No anxiety interventions were identified.

CONCLUSION

PST may reduce depressive symptoms post-intervention in older people with depression and functional impairments. Collaborative care appears to have few effects in this population. Future research needs to assess cost-effectiveness, long-term outcomes, and anxiety interventions for this population.

Problem-solving therapy reduces subjective burden levels in caregivers of family members with mild cognitive impairment or early-stage dementia: Secondary analysis of a randomized clinical trial

OBJECTIVES

Interventions addressing burden have limited impact among long-term family caregivers. We examined whether problem-solving therapy (PST) would reduce burden levels of caregivers of individuals diagnosed with mild cognitive impairment (MCI) or early-stage dementia (AD).

METHODS

Caregivers (N = 73) randomly received PST or nutritional training (NT). Burden measures were assessed over 1-year post-intervention.

RESULTS

Relative to NT, caregivers receiving PST endorsed improved perceived burden levels over time, regardless of the type of caregiver. Distress over the care recipient's dementia-related behaviors remained low over time among MCI caregivers receiving PST, while these burden levels among MCI caregivers receiving NT rose over time. AD caregivers receiving PST endorsed reductions in these burden levels over time, while AD caregivers in the NT group endorsed higher burden levels over time.

CONCLUSION

PST, taught early in the caregiving trajectory, improves subjective burden levels among caregivers of family members with relatively mild cognitive deficits.

Self-Management of Depression: Beyond the Medical Model

Self-management is increasingly becoming the standard of care among people with chronic medical conditions. Its application to depression is mostly extrapolated from the paradigms used for nonpsychiatric medical illnesses. Such an approach falls short in addressing strength-based interventions that foster recovery in individuals with depression. This article describes a new paradigm of self-management, which is in line with the recovery model, is patient-centered, and goes beyond amelioration of clinical symptoms.

Longitudinal Associations of Falls and Depressive Symptoms in Older Adults

Background and Objectives

Fall incidents and associated medical costs are increasing among older adults. This study examined longitudinal associations between older adults’ falls status and depression at 2 time periods to further clarify bidirectional relationships.

Methods

We used the National Health and Aging Trends Study (NHATS) Waves 5 and 6 data and included sample persons (N = 6,299) who resided in the community or residential care facilities (not nursing homes) at both waves (T1 and T2). We employed multinomial logistic regression analysis to examine the association of T2 falls status with T1 depressive symptoms, and negative binomial regression and logistic regression analyses to examine the association of T2 depressive symptoms with stability/change in T1-T2 falls status.

Results

Over the study period, 46% of older adults (18 million Medicare beneficiaries) who lived in the community or residential care facilities reported a fall. T1 depressive symptoms were significantly associated with greater odds of T2 multiple falls, and increasing falls or continuing incidents of multiple falls between T1 and T2 were significantly associated with higher depressive symptoms and probable major depression at T2.

Discussion and Implications

The significant bidirectional relationships between T1 depression and T2 multiple falls point to the importance of incorporating depression treatment in fall prevention programs for older adults at high risk of increasing/multiple falls.

Subthreshold Depression Needs A Prime Time In Old Age Psychiatry? A Narrative Review Of Current Evidence

This study aims to carry out a narrative review, aiming to update the literature on subsyndromic depression (SD), which is the most prevalent depressive disorder in older adults, and no formal guidelines or consensus are dedicated to this topic. We carried out an electronic search for articles on SD. Relevant articles were retrieved from Pubmed, EMBASE and Web of Science using the search terms "subthreshold depression," "prevalence," "treatment" and "older adults" in several combinations. Original articles in English were included from inception to 1st March 2019. No clear consensus exists in the literature on its nosologic classification, diagnostic tools, causes, course, outcomes or management. SD diagnosis should base in depressive symptoms scales and DSM criteria. Treatment relies mainly on collaborative care and psychotherapy. SD is relevant in clinical practice and research in geriatric psychiatry. Given the negative outcomes and potential benefits of treatment, we recommend brief psychotherapy as first-line treatment and use of psychotropic agents in cases with greater severity and/or functional impairment in association with psychotherapy. SD can precede major depressive disorder, but it also may consist of a primary depressive disorder in older adults. Furthermore, adequate treatment of SD can prevent or reduce negative outcomes associated with depressive symptoms such as worsening of clinical comorbidities, loss of functionality, increased demand for health services, and increased mortality.

Cyr N, Siddarth P. Resilience predicts remission in antidepressant treatment of geriatric depression

OBJECTIVES

With the world population rapidly aging, it is increasingly important to identify sociodemographic, cognitive, and clinical features that predict poor outcome in geriatric depression. Self-report measures of resilience-ie, the ability to adapt and thrive in the face of adversity-may identify those depressed older adults with more favorable prognoses.

METHODS

We investigated the utility of baseline variables including 4 factors of resilience (grit, active coping self-efficacy, accommodative coping self-efficacy, and spirituality) for predicting treatment response and remission in a 16-week randomized controlled trial of methylphenidate, citalopram, or their combination in 143 adults over the age of 60 with MDD.

RESULTS

Final logistic regression models revealed that greater total baseline resilience (Wald χ²  = 3.8, P = 0.05) significantly predicted both treatment response and remission. Specifically, a 20% increase in total resilience predicted nearly 2 times greater likelihood of remission (OR = 1.98, 95% CI = [1.01, 3.91]). Examining the individual factors of resilience, only accommodative coping self-efficacy (Wald χ²  = 3.7, P = 0.05; OR = 1.41 [1.00-2.01]) was significantly associated with remission. We found no relation between baseline sociodemographic factors (age, sex, race, education level) or measures of cognitive performance and posttreatment depressive symptoms.

CONCLUSIONS

Self-reported resilience may predict greater responsivity to antidepressant medication in older adults with MDD. Future research should investigate the potential for resilience training-and in particular, interventions designed to increase accommodative coping-to promote sustained remission of geriatric depression.

Comparative efficacy and acceptability of interventions for major depression in older persons: protocol for Bayesian network meta-analysis

INTRODUCTION

Major depression is a leading cause of disability and has been associated with adverse effects in older persons. While many pharmacological and non-pharmacological interventions have been shown to be effective to address major depression in older persons, there has not been a meta-analysis that consolidates all the available interventions and compare the relative benefits of these available interventions. In this study, we aim to conduct a systematic review and network meta-analysis to compare the efficacy and acceptability of all the known pharmacological and non-pharmacological interventions for major depression in older persons.

METHODS AND ANALYSIS

We will search Medline, Embase, PsycINFO, Cumulative Index to Nursing and Allied Health, Cochrane Central Register of Controlled Trials and references of other review articles for articles related to the keywords of 'randomised trial', 'major depression', 'older persons' and 'treatments'. Two reviewers will independently select the eligible articles. For each included article, the two reviewers will independently extract the data and assess the risk of bias using the Cochrane revised tool for risk of bias. Bayesian network meta-analyses will be conducted to pool the depression scores (based on standardised mean difference) and the all-cause discontinuation across all included studies. The ranking probabilities for all interventions will be estimated and the hierarchy of each intervention will be summarised as surface under the cumulative ranking curve (SUCRA). Meta-regression and sub-group analyses will also be performed to evaluate the effect of study-level covariates. The quality of the evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.

ETHICS AND DISSEMINATION

The results will be disseminated through conference presentations and peer-reviewed publications. They will provide the consolidated evidence to inform clinicians on the best choice of intervention to address major depression in older persons.

Problem-solving therapy for adult depression: An updated meta-analysis

BACKGROUND

Problem-solving therapy (PST) is one of the best examined types of psychotherapy for adult depression. No recent meta-analysis has examined the effects of PST compared to control groups or to other treatments. We wanted to verify whether PST is effective, whether effects are comparable to those of other treatments, and whether we could identify the possible sources of high heterogeneity that was found in earlier meta-analyses.

METHODS

We conducted systematic searches in bibliographical databases, including PubMed, PsycInfo, Embase and the Cochrane database of randomized trials.

RESULTS

We included 30 randomized controlled trials on PST (with 3530 patients), in which PST was compared to control conditions, with other therapies, and with pharmacotherapy. We could compare these 30 trials on PST also with 259 trials on other psychotherapies for adult depression. The effect size of PST versus control groups was g=0.79 (0.57-1.01) with very high heterogeneity (I²=84; 95% CI: 77-88). The effect size from the 9 studies with low risk of bias was g=0.34 (95% CI: 0.22-0.46) with low heterogeneity (I²=32; 95% CI: 0-68), which is comparable to the effects of other psychotherapies. PST was a little more effective than other therapies in direct comparisons, but that may be explained by the considerable number of studies with researcher allegiance towards PST. In meta-regression analyses of all controlled studies, no significant difference between PST and other therapies was found.

CONCLUSION

PST is probably an effective treatment for depression, with effect sizes that are small, but comparable to those found for other psychological treatments of depression.

Moderators in psychotherapy meta-analysis

Psychotherapy meta-analyses sometimes generate heterogeneous results, partially due to key methodological characteristics which vary between studies (e.g., psychotherapy conditions are contrasted with structurally different control conditions). Examining these potential moderator variables can help explain heterogeneous results within and between psychotherapy meta-analyses. The present manuscript provides an overview of moderators that are highly relevant to test the generalizability of effects across psychotherapy trials. These moderators mainly fall into one of the following groups: (a) structural equivalence of interventions, (b) preferences/allegiances, (c) therapist effects, and (d) sample representativeness. Individual moderators include: Bona fide psychotherapy, proximity to psychological interventions, psychotherapy orientation, pre-training of therapists, supervision, caseload of therapists, dosage, homework, patient preferences, researcher and therapist allegiance, therapist effects in nested designs, aspects of sample representativeness, multiple outcomes, and time of assessment. Our analysis of 15 psychotherapy meta-analyses published in 2016 suggests that the structural equivalence of psychotherapeutic conditions, patient and therapist preferences/allegiances, therapist effects and nested data structures as well as sample representativeness were often neglected and little-discussed as potential moderators. The manuscript describes further conceptual and methodological challenges when conducting moderator analyses such as the categorization of psychological treatments and the importance of interrater coding. We encourage meta-analysts to consider moderators which have previously shown utility in explaining heterogeneous results in the psychotherapy literature. Clinical or methodological significance of this article: Relevant moderator variables help explain heterogeneous results in psychotherapy meta-analyses. Though these variables are often overlooked, they should be regularly incorporated in meta-analyses.

Psychoeducation and Problem Solving (PEPS) Therapy for Adults With Personality Disorder: A Pragmatic Randomized-Controlled Trial

We compared psychoeducation and problem solving (PEPS) therapy against usual treatment in a multisite randomized-controlled trial. The primary outcome was social functioning. We aimed to recruit 444 community-dwelling adults with personality disorder; however, safety concerns led to an early cessation of recruitment. A total of 154 people were randomized to PEPS and 152 to usual treatment. Follow-up at 72 weeks was completed for 68%. PEPS therapy was no more effective than usual treatment for improving social functioning (adjusted difference in mean Social Functioning Questionnaire scores = -0.73; 95% CI [-1.83, 0.38]; p = 0.19). PEPS therapy is not an effective treatment for improving social functioning of adults with personality disorder living in the community.

Measuring Participant Effort in a Depression Prevention Trial: Who Engages in Problem-Solving Therapy?

OBJECTIVE

To determine the acceptability of clinical interventions for depression prevention, identification of clinical characteristics associated with intervention engagement is needed. The purpose of this study is to describe levels and correlates of participant engagement in Problem Solving Therapy (PST) in adults 60 and older with subthreshold depression.

METHODS

As part of a clinical trial to prevent depression among older adults with subthreshold depression, participants who were randomized to receive PST completed 6-8 sessions in which they learned skills to solve self-selected problems that were contributing to stress and reduced quality of life. To measure participants' engagement with PST, interventionists completed 3 scales that rated participants' level of participation in problem solving activities, understanding of the multistep process of PST, and between-session homework effort. Using logistic regression, we examined whether physical health, level of cognitive function, gait speed, and disability served as correlates of engagement in the PST intervention.

RESULTS

Gait speed, a measure of physical and cognitive health, was significantly associated with engagement in PST. Participants who walked faster were more likely to engage with PST compared to participants who walked more slowly. No other baseline variables were significant correlates.

CONCLUSIONS

Older adults who walk more slowly may need alternative delivery methods to fully engage in PST. Gait speed reflects physical and cognitive health, and predicts frailty, disability, and psychomotor speed slowing. For these reasons, gait speed may be a marker for factors that will serve to predict poorer engagement in psychosocial interventions like PST.

Psychosocial Treatment Options for Major Depressive Disorder in Older Adults

Late-life depression (LLD) is a public health concern with deleterious effects on overall health, cognition, quality of life, and mortality. Although LLD is relatively common, it is not a normal part of aging and is often under-recognized in older adults. However, psychotherapy is an effective treatment for LLD that aligns with many patients' preferences and can improve health and functioning. This review synthesized the current literature on evidence-based psychotherapies for the treatment of depression in older adults. Findings suggest that active, skills-based psychotherapies (cognitive behavioral therapy [CBT] and problem-solving therapy [PST]) may be more effective for LLD than non-directive, supportive counseling. PST may be particularly relevant for offsetting skill deficit associated with LLD, such as in instances of cognitive impairment (especially executive dysfunction) and disability. Emerging treatments also consider contextual factors to improve treatment delivery, such as personalized care, access, and poverty. Tele-mental health represents one such exciting new way of improving access and uptake of treatment by older adults. Although these strategies hold promise, further investigation via randomized controlled trials and comparative effectiveness are necessary to advance our treatment of LLD. Priority should be given to recruiting and training the geriatric mental health workforce to deliver evidence-based psychosocial interventions for LLD.
