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

Efficacy of problem-solving therapy in treating late-life depression with potential cognitive impairment: a systematic review and meta-analysis

INTRODUCTION

Late-life depression (LLD) is a global public health issue, often accompanied by cognitive impairments that can exacerbate the severity of depression and impair social functioning. Despite being a well-established treatment for LLD, the suitability of problem-solving therapy (PST) for individuals with LLD and varying degrees of cognitive impairments warrants further investigation. This paper presents the protocol for a systematic review and meta-analysis of randomised controlled trials (RCTs) aimed at evaluating the effectiveness and acceptability of PST for this specific demographic.

METHODS/ANALYSIS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we will conduct a systematic review to synthesise existing research on PST for individuals in this demographic. We will comprehensively search multiple databases and sources, including PubMed, EMBASE, the Cochrane Database and APA PsycNET from inception to October 2023, without language, publication year or type restrictions. Relevant studies will be manually screened from the references. Only RCTs involving PST for LLD will be included. The primary efficacy outcome will be the standardised mean difference in total scores on continuous depression severity scales across different comparison arms. Data extraction will be conducted independently by two reviewers (CH and J-JW), and methodological rigour will be assessed using the Cochrane Risk of Bias assessment tool. Subgroup and sensitivity analyses will be performed to investigate the impact of concomitant cognitive impairments and to evaluate the robustness of the findings.

ETHICS AND DISSEMINATION

The meta-analysis project is expected to be ethically unproblematic and does not require approval from a research ethics committee. The results of this study will be shared through articles in scholarly peer-reviewed journals and presentations in various formats, both print and digital.

Emotion regulation in older nursing home residents with and without depression and younger comparison samples

OBJECTIVES

We aimed to increase the understanding of emotion regulation (ER) and depression in older residents.

METHODS

A sample of depressed and non-depressed nursing home residents (N = 164, Mage = 82.63) were compared to younger patients with depression (N = 163, Mage = 37.4) and a non-clinical student sample (N = 635, Mage = 23.82). The Affective Style Questionnaire (ASQ), and in the older adults, cognitive capacity, access to people, and a facet of mindfulness were assessed. With two MANCOVAs ER was compared between the depressed and non-depressed participants.

RESULTS

Depressed and non-depressed individuals differed significantly regrading Adjusting and Tolerating after controlling for age, with an interaction significant for Tolerating (p = .034). Access to people and monitoring of experience were significant predictors of ER in residents.

CONCLUSIONS

Interventions that include ER for older patients in nursing homes as a possibility to reduce age related stereotypes are discussed.

Old-age mental telehealth services at primary healthcare centers in low- resource areas in Greece: design, iterative development and single-site pilot study findings

BACKGROUND

Even though communities in low-resource areas across the globe are aging, older adult mental and cognitive health services remain mainly embedded in tertiary- or secondary hospital settings, and thus not easily accessible by older adults living in such communities. Here, the iterative development of INTegRated InterveNtion of pSychogerIatric Care (INTRINSIC) services addressing the mental and cognitive healthcare needs of older adults residing in low-resource areas of Greece is depicted.

METHODS

INTRINSIC was developed and piloted in three iterative phases: (i) INTRINSIC initial version conceptualization; (ii) A 5-year field testing in Andros island; and (iii) Extending the services. The INTRINSIC initial version relied on a digital platform enabling videoconferencing, a flexible battery of diagnostic tools, pharmacological treatment and psychosocial support and the active involvement of local communities in service shaping.

RESULTS

Ιn 61% of the 119 participants of the pilot study, new diagnoses of mental and/or neurocognitive disorders were established. INTRINSIC resulted in a significant reduction in the distance travelled and time spent to visit mental and cognitive healthcare services. Participation was prematurely terminated due to dissatisfaction, lack of interest or insight in 13 cases (11%). Based on feedback and gained experiences, a new digital platform, facilitating e-training of healthcare professionals and public awareness raising, and a risk factor surveillance system were created, while INTRINSIC services were extended to incorporate a standardized sensory assessment and the modified problem adaptation therapy.

CONCLUSION

The INTRINSIC model may be a pragmatic strategy to improve access of older adults with mental and cognitive disorders living in low-resource areas to healthcare services.

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.

Community mental health interventions for people with major depressive disorder: A scoping review

People with major depressive disorder continue to be marred by chronically pernicious yet preventable outcomes in the biopsychosocial aspects. With the reallocation of healthcare resources towards the fight against the coronavirus 2019 pandemic, much emphasis has been placed on existing community mental health interventions to ameliorate the disruption of mental health services. Moreover, the recent propulsion of community mental health services by the World Health Organization Mental Health Action Plan 2013-2030 ignited the need to bolster existing community interventions by providing comprehensive, responsive and integrated mental healthcare. The enhanced emphasis on mental healthcare in the community and the heightened demands of people with major depressive disorder underscores the need to explore the current state of community mental health interventions. This scoping review examined 51 primary studies published from year 2010 to 2020 using Arskey & O'Malley's five-stage framework and provided an overview of the impact of existing community mental health interventions for people with major depressive disorder. Findings using thematic analysis have recommended the adoption of person-centred community mental healthcare via the biopsychosocial approach for people with major depressive disorder. Enablers of community mental health interventions were driven by culturally appropriate care and augmented by technology-driven modalities. Challenges and gaps of community mental health interventions include the perpetuation of stigma and misconception, complex demands of persons with major depressive disorder and lack of holistic and long-term outcomes. Given the impact of major depressive disorder on the various biopsychosocial aspects, it is envisioned that our insights into the enablers and barriers of community mental health interventions will guide prospective interdisciplinary and nurse-led interventions in holistically improving the care of persons with major depressive disorder in the community settings.

Depressive symptoms exacerbate disability in older adults: A prospective cohort analysis of participants in the MemAID trial

BACKGROUND

Maintaining independence in older age is an important aspect of quality of life. We investigated depressive symptoms as an important modifiable risk factor that may mediate the effects of physical and cognitive decline on disability.

METHODS

We prospectively analyzed data from 223 adults (age 50-85; 117 controls and 106 with type-2 diabetes) over 48 weeks who were participating in a clinical trial "Memory Advancement by Intranasal Insulin in Type 2 Diabetes." Data from self-reported disability (World Health Organization Disability Assessment Schedule) and depressive symptoms (Geriatric Depression Scale) were obtained from baseline, week 25, and week 48 visits. Cognition (Mini-mental status examination) and medical comorbidities (Charlson Comorbidity Index) were assessed at baseline. Longitudinal analysis assessed the extent to which change in depressive symptoms predicted worsening disability. Mediation analyses were performed to determine the extent to which depressive symptoms accounted for disability associated with worse cognition, walking speed, and comorbidities.

RESULTS

At baseline, depressive symptoms, cognition, and walking speed were within normal limits, but participants had a high 10-year risk of cardiovascular mortality. Depressive symptoms were related to disability at baseline (p<0.001), and longitudinally (p<0.001). Cognition, walking speed, and comorbidities were associated with disability at baseline (p-values = 0.027-0.001). Depressive symptoms had a large mediating effect on disability longitudinally: the indirect effect on disability via depression accounts for 51% of the effect of cognition, 34% of the effect of mobility, and 24% of the effect of comorbidities.

CONCLUSIONS

Depressive symptoms substantially exacerbated the effects of worsening cognition, gait speed, and comorbidities on disability. In our sample, most individuals scored within the "normal" range of the Geriatric Depression Scale, suggesting that even subclinical symptoms can lead to disability. Treating subclinical depression, which may be under-recognized in older adults, should be a public health priority to help preserve independence with aging.

The Relationship between Neuropsychiatric Symptoms and Cognitive Performance in Older Adults with Normal Cognition

Background and Objectives: To explore whether specific Neuropsychiatric Symptoms (NPS) are related to worse performance in particular cognitive domains. Materials and Methods: A cross-sectional analysis of the baseline evaluations of older (≥60 years), cognitively unimpaired (CU) participants from the National Alzheimer's Coordinating Center (NACC) Uniform Data Set was performed. Data were derived from 43 Alzheimer's Disease Research Centers. Cognitively impaired individuals, participants with psychiatric disorders and/or under treatment with antipsychotic, anxiolytic, sedative, or hypnotic agents were excluded. NPS were assessed using the Neuropsychiatric Inventory Questionnaire. The association of NPS with participants' performance on episodic memory, semantic memory, language, attention, processing speed and executive function was analysed using an adjusted (considering important demographic and medical factors) multivariate general linear model. Results: A total of 7179 CU, older, predominantly female, Caucasian, and well-educated participants were included in the present analysis. Among them, 1856 individuals had one or more NPS. Our analysis revealed that moderate/severe anxiety was related to worse performance on semantic memory, attention and executive function, the presence of hallucinations was linked to worse processing speed and executive function scores, while the presence of elation/euphoria and aberrant motor behaviour were associated with poorer attention and language performance, respectively. In the context of a secondary, exploratory analysis, the presence of moderate/severe delusions was related to worse processing speed and executive function performance. Conclusions: The relationship between specific NPS and worse performance in particular cognitive domains could inform the formulation of individualized preventive strategies directed to the ''fortification'' of specific cognitive functions in CU individuals with NPS.

Feasibility of Problem Adaption Therapy in a Diverse, Frail Older Adult Population (PATH-MHS)

The purpose of the Problem Adaptation Therapy - Montefiore Health System (PATH-MHS) pilot program was to demonstrate the feasibility and effectiveness of PATH across a culturally, educationally, and functionally diverse cohort of older adults.

METHODS

Clinicians referred 145 participants with depression and cognitive impairment to PATH-MHS. We completed analyses of the change in depression, disability and the association between baseline characteristics and remission of depression.

RESULTS

Most participants were Hispanic or Non-Hispanic Black and 54.7% (76) were primary Spanish speakers. Overall, there were significant decreases in the mean PHQ-9 and WHODAS 2.0 scores. In logistic regression models, neither age, education, gender, race/ethnicity, language nor long-term care status was significantly associated with remission of depression.

CONCLUSIONS

This study demonstrates that we were able to engage a diverse, cognitively impaired, and frail cohort of older adults in PATH-MHS with significant reductions in depression and disability.

Problem-solving training for Veterans in home based primary care: an evaluation of intervention effectiveness

BACKGROUND

Veterans enrolled in Veterans Health Administration (VHA) Home Based Primary Care (HBPC), a program providing in-home medical and mental health care by an interdisciplinary care team, often face substantial physical, cognitive, and mental health challenges. This program evaluation examined the impact of a brief problem-solving intervention on depressive symptoms, quality of life, and problem-solving abilities for Veterans enrolled in HBPC.

DESIGN

Pre- and post-intervention outcomes for Veterans, and qualitative feedback from Veterans and clinicians regarding program satisfaction.

PARTICIPANTS AND SETTING

A total of 230 HBPC patients (mean age in years = 72.1, SD = 11.6) within the U.S. national VHA health care system.

INTERVENTION

Six-session, individual Problem-Solving Training (PST-HBPC).

METHOD

Licensed psychologists and social workers (n = 115) completed training and administered the treatment with HBPC Veterans between 2014 and 2017.

MEASUREMENTS AND RESULTS

From baseline to post-intervention, Veterans completing five or more PST-HBPC sessions (n = 199) reported significant reductions in depressive symptoms on the Patient Health Questionnaire 9-item (PHQ-9), in difficulty functioning due to depressive symptoms (PHQ-9 item 10), and in thoughts of death (PHQ-9 item 9). They also reported more effective problem-solving on the Social Problem-Solving Inventory - Revised: Short form (total score and subscales), and improved quality of life across life domains on the World Health Organization Quality of Life-BREF (WHOQOL-BREF) scale. Both clinicians and Veterans also reported satisfaction with the program.

CONCLUSIONS

Preliminary findings support the continued dissemination and implementation of this brief PST intervention for HBPC Veterans, and its potential for use with non-VA home care populations with complex comorbidities.

Home/community-based interventions to improve function in persons with mild cognitive impairment/early dementia

Persons with mild cognitive impairment/early dementia have a possible 20-year trajectory of disability and dependence with little information on the effectiveness of interventions to improve function. This review investigates the literature of home/community-based interventions for physical and executive function in persons with mild cognitive impairment/early dementia. A 2007-2020 systematic literature search was conducted through PubMed, CINAHL Plus with Full Text and PsycINFO. Of the 1749 articles retrieved, 18 eligible studies were identified and consisted of three types of interventions: cognitive training-only (n = 7), multicomponent (n = 9), and physical activity-only (n = 2). Results showed that the interventions impacting function in persons with cognitive impairment incorporated a visual/written element, technology-based training, caregiver support, and modified duration/increased frequency of interventions. In studies improving function, participants simulated Instrumental Activities of Daily Living. They addressed cognitive function using both objective and subjective cognitive measures. We found gaps in the literature in incorporating race/ethnicity and appropriate socioeconomic status measures.

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.
