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

Chewing difficulties mediated association between edentulism and depressive symptoms among middle aged and older population

BACKGROUND

Depression is a major health condition among the aging population. Previous studies indicated that edentulism was a risk factor for depression. The link between edentulism and depression has not been fully clarified.

OBJECTIVES

This study aimed to estimate whether chewing difficulties play a mediating role in the association between edentulism and depression among middle-aged and older populations with national cross-sectional data.

METHODS

Data were obtained from the latest fourth wave of the China Health and Retirement Longitudinal Study (CHARLS). The outcome variable was set as depression, which was measured by the Center for Epidemiologic Studies Depression Scale (CES-D-10). Independent and mediated variables were separately set as self-assessed edentulism and chewing difficulties. The nearest neighbour propensity score matching (PSM) method was used to construct a matching group to balance the basic characteristics of individuals with and without edentulism with minimised bias in the estimation. Causal mediation analysis was performed to estimate the degree of contribution of chewing difficulties to the association between edentulism and depression. Several sensitivity analyses were performed to evaluate the robustness of the primary result.

RESULTS

A total of 15 853 individuals remained for analysis. After PSM, 809 individuals with edentulism and 2628 without edentulism remained for analysis. Among the matched individuals, the mean age was 66.3 ± 9.2 years, 58.5% were female, 78.8% lived in rural areas, 23.5% had edentulism, 51.1% had depressive symptoms, and 50.1% had chewing difficulties. Logistic regression results showed that a higher incidence of edentulism was associated with a higher rate of depression (OR: 1.39, 95% CI: 1.19-1.63) in the matching group. Causal mediation analysis results indicated that the average mediation effect of chewing difficulties on the association between edentulism and depression was 0.010 (95% CI: 0.005-0.015), and the average direct effect was 0.072 (95% CI: 0.036-0.11). The mediation proportion of chewing difficulties was 11.7% (95% CI: 0.079-0.21).

CONCLUSION

A higher prevalence of edentulism was associated with a higher rate of depression among middle-aged and elderly populations. Chewing difficulties moderately mediated the association between edentulism and depression. Fundamental oral function should not be neglected to improve mental health among the aging population.

Experiences of psychological interventions in neurodegenerative diseases: a systematic review and thematic synthesis

Background: Psychological interventions for managing emotional distress in neurodegenerative diseases are needed, but progressive worsening of symptoms and increasing disability might pose difficulties with engagement. We aimed to synthesise the experiences of engaging with and using psychological interventions in neurodegenerative diseases and identify relevant barriers and facilitators. Methods: Systematic searches were conducted in six electronic databases and results were screened. We included qualitative and mixed methods studies reporting patient or caregivers' views or experiences of psychological interventions. Qualitative data were extracted and thematically synthesised. Results: 34 papers were included, covering a range of diseases and interventions. Engagement was facilitated by flexible intervention formats and tailoring to the specific needs of people with neurodegenerative diseases. Interventions were sometimes inaccessible or burdensome because of physical and cognitive symptoms, and the time and effort required for the intervention. Participants' levels of acceptance and readiness often differed and influenced engagement with the intervention. Across different interventions, participants experienced wide-ranging benefits including changes in insight, perspective, self-efficacy, emotions and relationships. Conclusion: Although people with neurodegenerative diseases and caregivers experience benefits from psychological interventions, burden-reducing adaptations and sensitive tailoring to the specific disease context is required to improve acceptability and engagement.

Comparative effectiveness and acceptability of psychotherapies for late-life depression: A systematic review and network meta-analysis

BACKGROUND

The purpose of this systematic review and network meta-analysis is to compare the effectiveness and acceptability of psychotherapies for late-life depression.

METHODS

We searched PubMed, Embase, PsycINFO, CINAHL, The Cochrane Library, China National Knowledge Infrastructure, WANFANG database, and Chinese Biomedicine literature (CBM) for randomized controlled trials (RCTs) from their respective inception dates to March 30, 2022. Comparative effectiveness and acceptability of these psychological interventions were evaluated by conducting standard pairwise meta-analyses and network meta-analyses. A battery of analyses and assessments, such as the risk of bias and certainty of the evidence were performed.

RESULTS

A total of 68 studies with 4550 participants on six psychotherapies compared with two control groups were included in the final analysis. Notably, there were no statistically significant differences between behavioral activation therapy, cognitive behavior therapy (CBT), cognitive therapy, life review therapy, mindfulness, and combined psychotherapy. Compared with the non-active control group, six psychological interventions were statistically effective in reducing depression symptoms (standardized mean differences (SMDs) range, -1.08 to -0.73). While, only CBT, life review therapy, mindfulness, and combined psychotherapy were more effective than the active control group (SMDs range, -0.85 to -0.74). Life review therapy was ranked as the best option according to effectiveness and acceptability, while behavioral activation therapy was the worst by acceptability. The certainty of the evidence was mostly rated as low to very low.

CONCLUSIONS

Despite the scarcity of high-quality evidence, all six psychotherapies were effective for late-life depression, and life review therapy seemed to be the best choice in terms of effectiveness and acceptability. The findings of our review could provide policymakers and service commissioners with evidence-based practice for making decisions among different psychotherapies.

Effects of Serious Games on Depression in Older Adults: Systematic Review and Meta-analysis of Randomized Controlled Trials

BACKGROUND

Depression is a severe psychological concern that negatively affects health in older adults. Serious games applied in various fields are considered appropriate interventions, especially in mental health care. However, there is a lack of evidence regarding the effects of serious games on depression in older adults.

OBJECTIVE

This study aimed to investigate the characteristics and effectiveness of serious games for depression in older adults.

METHODS

A systematic review and meta-analysis of randomized controlled trials were conducted. In total, 5 electronic databases (PubMed, CINAHL, Embase, PsycINFO, and Cochrane Library) were searched to identify relevant studies published until July 6, 2021. A total of 2 reviewers independently conducted study selection, data extraction, and quality appraisals. The risk of bias in the included studies was assessed using the JBI Critical Appraisal Checklist. For the meta-analysis, the effect size was calculated as the standardized mean difference (SMD) by using a random effects model.

RESULTS

A total of 17 studies with 1280 older adults were included in the systematic review, and 15 studies were included in the meta-analysis. Serious game interventions were classified into 3 types: physical activity (PA), cognitive function, and both PA and cognitive function. The meta-analysis demonstrated that serious games reduced depression in older adults (SMD -0.54, 95% CI -0.79 to -0.29; P<.001). Serious games had a more significant effect size in community or home settings (SMD -0.61, 95% CI -0.95 to -0.26; P<.001) than in hospital settings (SMD -0.46, 95% CI -0.85 to -0.08; P=.02); however, the difference between groups was not significant. Among the types of games, games for PA (SMD -0.60, 95% CI -0.95 to -0.25; P<.001) and games for both (SMD -0.73, 95% CI -1.29 to -0.17; P=.01) had a significant effect on reducing depression in older adults. However, no significant correlations were observed between the duration or number of serious games and depression.

CONCLUSIONS

Serious games were beneficial in reducing depression in older adults. Regardless of the study setting, serious games appeared to reduce depression. Particularly, serious games including PA had a significant impact on reducing depression. Furthermore, high-quality randomized controlled trials are needed to establish substantial evidence for the effectiveness of serious games on depression in older adults.
