Psychosocial interventions for mental disorders in late life: are we making progress toward efficiency and impact?

Mental and physical activities delay cognitive decline in older persons with dementia

OBJECTIVES

To examine the effects of cognitive stimulation (mahjong) and physical exercise (tai chi [TC]) on cognitive performance in persons with dementia.

DESIGN

Cluster-randomized open-label controlled design.

SETTING

Nursing homes.

PARTICIPANTS

One hundred ten residents, most of whom were cholinesterase-inhibitor naive. Inclusion criteria were Mini-Mental State Examination (MMSE) = 10-24 and suffering from at least very mild dementia (Clinical Dementia Rating ≥ 0.5). Exclusion criteria were being bedbound, audio/visual impairment, regular activity participation before study, or contraindications for physical or group activities.

INTERVENTIONS

Homes were randomized into three conditions (mahjong, TC, and simple handicrafts [control]). Activities were conducted three times weekly for 12 weeks.

MEASUREMENTS

Primary outcome was MMSE. Secondary outcomes were immediate/delayed recall, categorical fluency, and digit span. Various biological risk factors, including apolipoprotein E ε4 allele, were included as covariates. Measures were collected at 0 (baseline), 3 (posttreatment), 6, and 9 months.

RESULTS

Intent-to-treat analyses were performed using mixed-effects regression. Mahjong's effect varied by time for MMSE, delayed recall, and forward digit span. TC had similar effects but not for delayed recall. The typical pattern was that control participants deteriorated while mahjong and TC participants maintained their abilities over time, leading to enlarged treatment effects as time progressed. By 9 months, mahjong and TC differed from control by 4.5 points (95% confidence interval: 2.0-6.9; d = 0.48) and 3.7 points (95% confidence interval: 1.4-6.0; d = 0.40), respectively, on MMSE. No treatment effects were observed for immediate recall and backward digit span.

CONCLUSIONS

Mahjong and TC can preserve functioning or delay decline in certain cognitive domains, even in those with significant cognitive impairment.

Dissemination and implementation of evidence-based practices for child and adolescent mental health: a systematic review

OBJECTIVE

Although there has been a dramatic increase in the number of evidence-based practices (EBPs) to improve child and adolescent mental health, the poor uptake of these EBPs has led to investigations of factors related to their successful dissemination and implementation. The purpose of this systematic review was to identify key findings from empirical studies examining the dissemination and implementation of EBPs for child and adolescent mental health.

METHOD

Of 14,247 citations initially identified, 73 articles drawn from 44 studies met inclusion criteria. The articles were classified by implementation phase (exploration, preparation, implementation, and sustainment) and specific implementation factors examined. These factors were divided into outer (i.e., system level) and inner (i.e., organizational level) contexts.

RESULTS

Few studies used true experimental designs; most were observational. Of the many inner context factors that were examined in these studies (e.g., provider characteristics, organizational resources, leadership), fidelity monitoring and supervision had the strongest empirical evidence. Albeit the focus of fewer studies, implementation interventions focused on improving organizational climate and culture were associated with better intervention sustainment as well as child and adolescent outcomes. Outer contextual factors such as training and use of specific technologies to support intervention use were also important in facilitating the implementation process.

CONCLUSIONS

The further development and testing of dissemination and implementation strategies is needed to more efficiently move EBPs into usual care.
