An occupation-based strategy training approach to managing age-related executive changes: a pilot randomized controlled trial

A meta-analysis on the relationship between subjective cognitive failures as measured by the cognitive failures questionnaire (CFQ) and objective performance on executive function tasks

The Cognitive Failures Questionnaire (CFQ) has been widely used as a measure of subjective cognitive function in everyday life for decades. However, the evidence on how it relates to objective performance on executive function tasks is mixed. One possible reason for these mixed results is that the CFQ has selective relationships with some aspects of executive function and not others. Here, therefore, we classified tasks according to an influential framework of executive functions-switching, updating, inhibition, and we also considered the Sustained Attention to Response Task (SART) as a category because it was custom designed to gauge cognitive failures. We synthesized a large body of available evidence and performed four Bayesian meta-analyses on the relationship between CFQ scores and objective performance on executive function tasks in these four categories. Results suggested that CFQ scores were associated with objective performance on SART (18 effect sizes, μ = -.19, BF10 = 18.03, i.e., 18.03 times more evidence of a relationship versus no relationship), updating working memory (49 effect sizes, μ = -.06, BF10 = 17.80), and inhibition tasks (41 effect sizes, μ = -.07, BF10 = 15.40), whereas there was not definitive evidence regarding switching (34 effect sizes, μ = -.06, BF10 = .50, i.e., two times greater evidence for no relationship). This suggests that subjective cognitive function can predict objective performance on at least some executive function tasks. We discuss methodological and theoretical factors that constrain the maximum observable correlation and consider the relative insights that subjective measures versus task performance provide.

Feasibility of using the Cognitive Orientation to daily Occupational Performance in a population of Danish stroke survivors: Adaptation and study protocol

BACKGROUND

A need was identified for an occupational therapy intervention for stroke survivors in a Danish municipal healthcare setting with emphasis on its ability to transfer and generalise what is learned in occupational therapy to everyday life post therapy. Being a possible candidate, the Cognitive Orientation to daily Occupational Performance (CO-OP) approach needed to be adapted to the target group and context, and its feasibility needed examination regarding reach, dose, intervention components, fidelity, perceived value, benefits, harms, and potential outcomes.

AIM

To adapt the CO-OP to a Danish healthcare setting and present a protocol for examining its feasibility.

MATERIAL AND METHODS

The Adapting interventions to new contexts (ADAPT) guidance was followed to (1) Assess the rationale for intervention and consider intervention-context fit, (2) Plan and undertake adaptations, and (3) Plan a feasibility study.

RESULTS

Intervention materials and procedures were translated and adapted for home-based occupational therapy with people in the subacute phase of stroke. A protocol was developed to examine feasibility aspects. Quantitative and qualitative evaluations were planned and measurements chosen.

CONCLUSIONS AND SIGNIFICANCE

The planned feasibility study will contribute to further developing and refining the intervention before performing a possible large-scale effectiveness study.

Cognitive Retraining and Functional Treatment (CRAFT) for adults with cancer related cognitive impairment: a preliminary efficacy study

PURPOSE

To examine the preliminary efficacy of Cognitive Retraining and Functional Treatment (CRAFT) combining remote computerized cognitive training (CCT) and occupation-based treatment in adults with cancer-related cognitive impairment (CRCI).

METHODS

Three-armed randomized controlled trial including 74 individuals with CRCI, randomized into 12 weeks of either CRAFT, CCT alone, or treatment-as-usual. Assessments evaluating participation in daily life, perceived cognition, cognitive performance, quality-of-life, and treatment satisfaction were administered at baseline, post-intervention, and 3-month follow-up.

RESULTS

Significant time × group interactions in favor of the CRAFT and CCT groups were found for participation in daily life (F_2,34 = 5.31, p = .01, eta = .238), perceived cognition (F_2,34 = 4.897, p = .014, eta = .224), and cognitive performance on speed of processing test (F = 5.678, p = .009, eta = .289). The CRAFT group demonstrated significantly larger clinically meaningful gains on participation in daily life (chi-square = 6.91, p = .032) and significantly higher treatment satisfaction. All treatment gains were maintained at a 3-month follow-up (n = 32).

CONCLUSIONS

CCT and CRAFT were found to have a positive impact on participation and cognitive outcomes among individuals with CRCI. The CRAFT showed an additional advantage in improving self-chosen occupation-based goals suggesting that a combination of cognitive training with occupation-based intervention has a positive synergistic effect resulting in "real world" health benefits.

IMPLICATIONS FOR CANCER SURVIVORS

A combination of cognitive training with occupation-based intervention has a positive effect resulting in clinically meaningful improvements in participation in daily life, objective cognitive performance, and subjective cognitive impairment.

Cognitive Orientation to daily Occupational Performance (CO-OP) for Older Adults After a Hip Fracture: A Pilot Study

IMPORTANCE

In-home therapy provides the opportunity for rehabilitation intervention to be completed in the context of the patient's natural environment. However, most studies have focused on the effects of physical exercise, leaving a gap in understanding the effectiveness of a more task-oriented intervention that addresses individual preferences.

OBJECTIVE

To assess the feasibility and preliminary efficacy of the Cognitive Orientation to daily Occupational PerformanceTM (CO-OP) approach, delivered at home with older adults after a hip fracture to improve functional outcomes.

DESIGN

Single-arm quasi-experimental design.

SETTING

Patients' home.

PARTICIPANTS

Nine participants (age ≥60 yr) being discharged home from an inpatient rehabilitation ward in a geriatric hospital in a central city in Israel.

INTERVENTION

Up to 10 1-hr weekly face-to-face sessions in using the CO-OP approach.

OUTCOMES AND MEASURES

The Canadian Occupational Performance Measure was used to measure performance and satisfaction with the patients' level of participation in daily functioning.

RESULTS

A 30% recruitment rate, an 81% retention rate, were observed, with 88% of the participants expressing high to very high overall satisfaction with the intervention. Friedman test results indicated statistically significant improvements in occupational performance and satisfaction on trained and untrained goals (p < .01).

CONCLUSIONS AND RELEVANCE

The findings suggest that a home-based CO-OP intervention is feasible and potentially beneficial for older adults who are returning home after a hip fracture. What This Article Adds: This study shows that a task-oriented intervention can be effective in helping older adults return home successfully after a hip fracture.

Strengthening problem-solving skills through occupational therapy to improve older adults' occupational performance - A systematic review

Background: Evidence supports the role of occupational therapy (OT) for older adults, and therapeutic use of problem solving may provide a way to improve older adult's occupational performance.Aim: To assess the effectiveness and describe the contents of OT interventions aimed at improving older adults' occupational performance by strengthening their problem-solving skills.Material and Methods: This systematic review followed the phases recommended by the Cochrane Collaboration. The following databases were searched for clinical trials on OT for populations 65+ years: CINAHL, EMBASE, MEDLINE and PsycINFO. The Cochrane risk-of-bias tool (RoB-2) and the GRADE approach were used to assess the quality of the evidence. Results were presented in tables and by narrative syntheses.Results: Five studies were included comprising a total of 685 participants. In four studies, OT with a problem-solving approach outperformed control conditions post intervention. The interventions involved problem identification, analysis, strategy development and implementation. Although no serious risk of bias was detected in the individual studies, the quality of evidence was deemed low due to inconsistent and imprecise results.Conclusions: Low-quality evidence suggests that strengthening older adults' problem-solving skills may improve their occupational performance.Significance: Further investigation is required before firm practice recommendations can be prepared.

Cognitive Strategies: Moderating the Relationship between Executive Functions and Daily Functioning

Whereas prior studies have addressed relationships between cognitive strategies and learning and achievement, very few dealt with their connection to daily functioning. This study examines the moderation effect of the frequency of compensatory cognitive strategy use within that relationship among university students. A sample of 336 students (18-36 years; 180 women, 156 men) answered the Dysexecutive Questionnaire (DEX; executive function components), Time Organization and Participation Scale (TOPS; daily functioning), and Compensatory Cognitive Strategies Scale (CCSS; strategy use). The results showed significant correlations between the DEX and TOPS for three CCSS levels (-1.0, -1.0 to 1.0, and 1.0 SD from average); the higher the frequency of cognitive strategy use, the stronger the association between the DEX and TOPS. The findings suggest that more frequently use of cognitive strategies can strengthen efficient daily functioning.

Combining elements of the CO-OP Approach™ with education to promote healthy eating among older adults: A pilot study

This paper describes an exploratory study developing the Baycrest Brain-healthy Eating Approach (BBEA). Poor diet is a modifiable risk factor for many health problems including dementia. Mediterranean type diets, high in plant-based foods, rich in poly- and mono- unsaturated fatty acids with minimal consumption of saturated fat, red meat, and processed foods, are considered brain healthful. While several dementia prevention trials randomized controlled trials have included nutritional counselling in favor of these diets as one component of their interventions, the extent to which dietary change occurred is not known. Based on observations that a strategy training approach, the Cognitive Orientation to daily Occupational Performance (CO-OP) Approach, was beneficial for promoting lifestyle changes in older adults with complaints of cognitive changes, we undertook to develop the BBEA combining elements of CO-OP with didactic nutrition education. This exploratory, descriptive study assesses the feasibility and acceptability of the BBEA. Healthy community dwelling older adults (n = 5) were recruited using convenience sampling. Participants received five, 2 h, group sessions. During these sessions participants were supported in adopting dietary practices consistent with brain healthy eating. Each participant set specific dietary goals important to them. Feasibility of the intervention was demonstrated through high levels of attendance and by the findings that at each session, all participants set personally meaningful goals and received education on selected brain healthy eating topics. Acceptability was demonstrated through participants' positive reports of their experiences and perspectives obtained via semi-structured interviews. Thus, the BBEA appears to be feasible and acceptable.

Psychosocial modification of general self-efficacy in older adults: A restricted review

OBJECTIVES

In recent years, the concept of general self-efficacy has increased in popularity. General self-efficacy is positively associated with quality of life and has the potential to act as a psychological buffer against adverse events and circumstances. However, due to the long-term influences that are said to shape general self-efficacy beliefs, they may be resistant to intervention, particularly within the older population. This restricted review aimed to explore whether psychosocial interventions could improve the general self-efficacy of older adults. Aspects of intervention design associated with improvements were also investigated.

METHODS

A restricted review was undertaken. This included a keyword search of four major health databases (PubMed, CINAHL, PsycINFO and AgeLine). Search terms focused on general self-efficacy and the commonly used measures of this concept and were limited to the older adult population.

RESULTS

In total, 848 articles were screened, with 20 studies proceeding to data extraction. The modification of general self-efficacy in older adults appears possible, with 7 out of the 20 included studies reporting improvements postintervention. Despite issues relating to the quality of included studies and the generalisability of their results, several aspects of intervention design coincided with intervention success, including intervention duration, and employing sufficiently-qualified staff.

CONCLUSIONS

Future research must address the generalisability issues identified in this review. Studies comparing the effectiveness of individual- and group-based interventions, the efficacy of remote delivery platforms and the possibility for long-term transfer of any improvements are needed to contribute the high-quality data required for policy and practice decisions in this area.

Characterizing Cognition in Everyday Life of Older Adults With Subjective Cognitive Decline

Subjective cognitive decline (SCD), the subjective experience of worsening cognition with no objective cognitive impairment, poses a heightened risk for dementia. This study aimed to characterize cognition in the everyday life of people with SCD, is crucial for understanding and preventing further functional and cognitive decline. One hundred and thirty-five older adults (age 70.7±6.7) with SCD were assessed using functional-cognition measures: Multifactorial Memory Questionnaire (MMQ), Behavior Rating Inventory of Executive Function–Adult version (BRIEF-A), and Multiple Errands Test (MET). The resulted showed that older adults with SCD reported lower memory satisfaction (Hedges’s g = 0.41) on the MMQ, and worse metacognition on the BRIEF-A (Hedges’s g = 0.63) compared with published normative data. They completed an average of only 6/12 required tasks on the MET. The findings show functional difficulties related to SCD and inform the development of occupational therapy intervention for this population.

Feasibility and preliminary efficacy of the LEAD trial: a cluster randomized controlled lifestyle intervention to improve hippocampal volume in older adults at-risk for dementia

BACKGROUND

Healthy diet and exercise are associated with reduced risk of dementia in older adults. The impact of diet and exercise interventions on brain health is less consistent, especially with dietary interventions which rely on varying approaches. Our objective was to evaluate the feasibility and preliminary efficacy of a 6-month intervention combining exercise with a novel dietary counseling approach to improve hippocampal volume among older adults at-risk for dementia.

METHODS

Participants with vascular risk factors and subjective cognitive decline or early mild cognitive impairment were cluster randomized in groups of 3-4 to the diet intervention (DIET) or control education (ED) group. All participants engaged in 1 h of supervised exercise per week and additional exercise at home. DIET involved 1 h per week of group-based dietary counseling comprising education, goal setting, and strategy training. ED involved 1 h per week of group-based brain health education classes. Our primary outcome was change in hippocampal volume from baseline to 6 months. Secondary outcomes included changes in cognitive function, blood biomarkers, diet, and fitness. Recruitment challenges and early discontinuation of the trial due to COVID-19 necessitated a revised focus on feasibility and preliminary efficacy.

RESULTS

Of 190 older adults contacted, 14 (7%) were eligible and enrolled, constituting 21% of our recruitment target. All participants completed the intervention and attended 90% of exercise and DIET/ED sessions on average. All 6-month assessments prior to COVID-19 were completed but disruptions to in-person testing resulted in incomplete data collection. No serious adverse events occurred and all participants expressed positive feedback about the study. Preliminary findings did not identify any significant changes in hippocampal volume; however, substantial improvements in diet and HbA1c were observed with DIET compared to ED (d = 1.75 and 1.07, respectively).

CONCLUSIONS

High adherence and retention rates were observed among participants and preliminary findings illustrate improvements in diet quality and HbA1c. These results indicate that a larger trial is feasible if difficulties surrounding recruitment can be mitigated.

Can strengthening older adults' problem-solving skills through occupational therapy improve their occupational performance? A protocol for a systematic review and meta-analysis

BACKGROUND

Older adults' occupational performance is challenged due to chronic health conditions, aging processes, and deteriorating functioning. Thus, their occupational performance cannot be expected to remain stable in the long term after an occupational therapy intervention. Older adults may therefore need to strengthen their problem-solving skills during occupational therapy not only to solve current occupational performance issues but also to maintain their improvements and deal with new such issues a later point in time.

AIMS

This systematic review and meta-analysis aims to identify, analyse and present current scientific knowledge about the effectiveness and contents of occupational therapy interventions aimed at improving older adults' occupational performance by strengthening their problem-solving skills.

METHODS

MEDLINE, EMBASE, CINAHL and PsycINFO will be searched systematically to identify trials of occupational therapy interventions aimed at improving older adults' occupational performance by strengthening their problem-solving skills. We will include randomized controlled trials and quasi-experimental trials in populations aged 65+. Three reviewers will independently screen and select references, extract data and assess the quality of included studies using the Cochrane Collaboration's risk of bias tool.

SIGNIFICANCE

The findings can inform and inspire clinical practice and will help to identify the need for further research.

Occupational performance issues in older adults with subjective cognitive decline

PURPOSE

To describe and categorize difficulties in daily activities of older adults with subjective cognitive decline (SCD) compared to individuals with mild cognitive impairment (MCI).

METHODS

Deductive quantitative content analysis was used to classify reported issues in the performance of meaningful daily activities, in older adults with SCD (n = 67; age= 70 ± 6.3) or MCI (n = 42; age= 72 ± 6.6). The occupational performance issues were identified using the Canadian Occupational Performance Measure, a semi-structured interview, and categorised using the International Classification of Functioning, Disability and Health (ICF).

RESULTS

Both groups identified issues in all nine ICF "Activities and Participation" domains, with no significant group effects on seven of them. The most frequently affected "Activities and Participation" domains in both groups were "Self-care" (e.g. exercise and diet); "Community, social and civic life" (e.g. social-leisure activities); and "General tasks and demands" (e.g. time management). Over 90% of the issues in both groups were described in the context of difficulties in "Mental functions" (e.g. memory and higher-level cognitive functions).

CONCLUSIONS

Older adults with SCD, although independent, identified a variety of daily activities that they are not performing satisfactorily, remarkably similar in nature to the occupational performance issues described by older adults with MCI.Implications for RehabilitationOlder adults with SCD identified difficulties in performing social and leisure activities, maintaining healthy lifestyle behaviours, and managing multiple daily tasks.The daily challenges described by older adults with SCD are similar in nature to those identified by those with MCI.Older adults with SCD and MCI describe their daily challenges are related not only to memory problems, but also to executive dysfunction.Interventions for older adults with SCD should aim to improve self-identified problems in everyday functioning.

Efficacy of lifestyle and psychosocial interventions in reducing cognitive decline in older people: Systematic review

It is unclear what non-pharmacological interventions to prevent cognitive decline should comprise. We systematically reviewed lifestyle and psychosocial interventions that aimed to reduce cognitive decline in healthy people aged 50+, and people of any age with Subjective Cognitive Decline or Mild Cognitive Impairment. We narratively synthesised evidence, prioritising results from studies rated as at lower Risk of Bias (ROB) and assigning Centre for Evidence Based Medicine grades. We included 64 papers, describing: psychosocial (n = 12), multi-domain (n = 10), exercise (n = 36), and dietary (n = 6) interventions. We found Grade A evidence that over 4+ months: aerobic exercise twice weekly had a moderate effect on global cognition in people with/ without MCI; and interventions that integrate cognitive and motor challenges (e.g. dance, dumb bell training) had small to moderate effects on memory or global cognition in people with MCI. We found Grade B evidence that 4+ months of creative art or story-telling groups in people with MCI; 6 months of resistance training in people with MCI and a two-year, dietary, exercise, cognitive training and social intervention in people with or without MCI had small, positive effects on global cognition. Effects for some intervention remained up to a year beyond facilitated sessions.

Changes in Activity Participation Among Older Adults With Subjective Cognitive Decline or Objective Cognitive Deficits

Participation in daily activities is crucial for healthy aging. There is limited research on participation of older adults with subjective cognitive decline (SCD), defined as the experience of cognitive deficits with no evidence of objective cognitive deficits. Therefore, this study examined perceived changes in participation in this population, and compared it to perceived changes reported by individuals with objective cognitive deficits. The study aimed to: (1) examine the reported changes in activity participation of older with SCD; (2) investigate differences in the reported changes in participation between individuals with SCD and those with mild or severe objective cognitive deficits; (3) examine the relationship between activity participation, subjective memory, and objective cognitive status; and (4) explore whether subjective memory explains additional variance in activity participation after accounting for age and objective cognitive deficits. Participants were 115 older adults (60+), divided into three groups based on their Montreal Cognitive Assessment (MoCA) scores: (1) SCD (MoCA≥26; n = 66); (2) mild objective cognitive deficits (MoCA = 20-25; n = 34); and (3) severe objective cognitive deficits (MoCA ≤ 19; n = 15). The Activity Card Sort was used to measure participation in instrumental activities of daily living, social, and leisure activities. The Multifactorial Memory Questionnaire-Ability subscale was used to assess subjective memory. We found that individuals with SCD, mild cognitive deficits and severe cognitive deficits reported participation withdrawal to a level of 80, 70, and 58% of their past participation, respectively. A significant between group difference was found on participation [χ2(2) = 16.44, p < 0.01], with the SCD group reporting higher participation than the other two groups. Participation significantly correlated with both cognitive status (r = 0.40, p < 0.01) and subjective memory (r = 0.45, p < 0.05). A regression analysis revealed that subjective memory contributed significantly to the explained variance in participation, beyond that accounted for by objective cognitive deficits and age. Our findings demonstrate the important role of subjective memory problems in activity participation of older adults, even in the absence of objective cognitive deficits.

Cognitive orientation to daily occupational performance approach in adults with neurological conditions: A scoping review

Background: The Cognitive Orientation to daily Occupational Performance (CO-OP) approach, top-down, client-centered and goal-oriented approach originally developed for children with Developmental Coordination Disorder (DCD) in 2001 and since used in other populations and settings. The purpose of this scoping review was to examine the extent (number) and nature (features and characteristics) of the literature on CO-OP in adult’s populations.

Methods: In this scoping review, 8 online databases were searched up to April 2018 to identify articles that addressed CO-OP in adult’s populations. The articles were selected based on inclusion and exclusion criteria. Two raters reviewed all documents independently. Articles were categorized according to diagnosis.

Results: Fifteen studies were identified. To examine application and effectiveness of CO-OP in adult’s populations we included individuals with chronic stroke (>6 months post-stroke; n=7), with TBI (n=3), with acute stroke (<6 months post-stroke; n=4) and the older adult populations comprised those with self-reported cognitive difficulties but no diagnosis of dementia, depression, or cognitive impairment (n=1). In all cases, CO-OP showed to be useful and efficient.

Conclusion: CO-OP has been applied in TBI, stroke and age-related executive changes appropriately. The results have shown that CO-OP efficiently improved performance and satisfaction in trained and not trained client chosen goals.

The impact of behavioral interventions on cognitive function in healthy older adults: A systematic review

Behavioral interventions to improve cognitive function in older adults are widespread and can vary from theater classes to cognitive training programs. However, the effectiveness in maintaining different cognitive domains varies greatly both across and within intervention types. To date, no systematic reviews have synthesized findings across more than a few types of interventions (e.g., cognitive vs. exercise). This systematic review examined 11 types of behavioral interventions and the respective transfer to 19 cognitive domains, as well as transfer to everyday function. Study inclusion criteria were: peer-reviewed articles in English, samples of healthy adults aged 65 and older, and randomized controlled trials of behavioral interventions with reported cognitive outcomes. The 2017 search yielded 75 eligible articles comprising cognitive training, exercise training, combination interventions, cognitively-stimulating activities, and action video games. In general, process- (n = 26) and strategy-based (n = 16) cognitive training improved the trained domains but had weak transfer to non-trained domains. Aerobic training (n = 13) most consistently improved executive function, and strength/resistance (n = 8) and aerobic/resistance combination training (n = 6) most consistently improved cognitive inhibition and visual working memory. Combination interventions (n = 15 nonfactorial, n = 3 factorial) showed promise in improving verbal delayed recall and executive function. Few studies examined cognitively-stimulating activities or action video games, leaving inconclusive results about their effect on cognitive function. Few studies examined everyday function (n = 9), however, process- and strategy-based training demonstrated notable long-term transfer. Recommendations for future research and practice are highlighted.

Preventing disability in older adults with mild cognitive impairment: A Strategy Training intervention study

Non-pharmacological interventions designed to change cognitive function in older adults with Mild Cognitive Impairment have shown mixed results. Few studied interventions directly address preclinical disability. Slowing changes in disability are critical preserve independence and health related quality of life in older adults with Mild Cognitive Impairment. In this study, we discuss the design of the trial, challenges encountered, and solutions generated to guide future trials designed to prevent the onset of disability among at-risk older adults. We compared Strategy Training to enhanced-usual care in 30 older adults with Mild Cognitive Impairment. We recruited 79.7% (n = 188) of the potential participants through direct-to-consumer recruitment. We refined a three-step screening process, including a phone screen, initial in-person screening, and full in-person screening. This screening processes resulted in a high percentage of older adults completing the neuropsychological battery and adjudication of Mild Cognitive Impairment. Conducting a disability prevention among individuals without overt disability is a novel approach. Nevertheless, one of the greatest limitations to our project is the fact that follow-up is restricted to 1 year. Findings from this study can inform the design and conduct of future clinical trials that seek to slow progression of disability in older adults with Mild Cognitive Impairment.

Reliability and validity of the Assessment of Client's Enablement (ACE)

Introduction

Goal-setting in client-centred occupational therapy is often problematic. The Assessment of Client's Enablement was developed to measure the gap between an occupational therapist's and client's ratings of occupational performance. This study examines the reliability and convergent validity of the assessment.

Method

The assessment was used by 22 occupational therapists with 44 clients. Convergent validity was examined between the assessment (client, occupational therapist and gap scores), Canadian Occupational Performance Measure performance and Functional Independence Measure scores. Test–retest reliability was assessed by intraclass correlation coefficient. Forty-four clients participated in the test–retest reliability study.

Findings

Good-to-moderate correlation was found in the assessment scores (intraclass correlation coefficients of 0.86, 0.95 and 0.78 for client, occupational therapist and gap scores, respectively). The validation study was completed by 34 clients. The correlation between Canadian Occupational Performance Measure and Assessment of Client's Enablement scores was significant (client score, Spearman’s Rank Order Correlation (rs) = 0.47; occupational therapist score, rs = 0.45). The correlation between Functional Independence Measure and the assessment's occupational therapist scores was significant (rs = 0.43).

Conclusion

The study confirms the reliability and convergent validity of the Assessment of Client's Enablement. The assessment requires less time to administer than similar instruments and requires no formal training, making it feasible in rehabilitation settings.

Developing a Non-Pharmacological Intervention for Individuals With Mild Cognitive Impairment

The purpose of this study is to describe one potential intervention model that is designed to slow decline to disability for individuals at-risk for dementia due to Mild Cognitive Impairment. Strategy training is a treatment model that focuses on behavioral activation through addressing barriers to daily activities. Strategy training encourages development of goals and plans to address self-identified impaired processes, and it maintains or improves individuals' ability to perform desired activities. Progression to dementia may be slowed due to the link between engagement in daily activities and production of biological factors associated with neurocognitive health. We demonstrated that an older adult with mild cognitive impairment is able to develop goals, establish effective plans, and engage in daily activities through the strategy training intervention model.

The Cognitive Orientation to Daily Occupational Performance Approach and Transfer: A Scoping Review

Transferring learning from therapy to everyday life skills is a necessary step for successful therapy outcomes, yet rarely addressed and achieved. However, a cognitive approach to skill acquisition, and the Cognitive Orientation to daily Occupational Performance (CO-OP), explicitly identifies transfer as an objective and incorporates elements into the intervention to support transfer. A scoping review was undertaken to explore the nature and extent of the research regarding CO-OP and transfer. An online search of 10 databases was conducted to identify and examine research studies reporting on CO-OP and transfer. The search yielded 25 documents that addressed CO-OP and transfer. The studies used a variety of approaches to evaluate transfer; all reported transfer on at least one and, in many cases, multiple transfer outcome variables. The CO-OP literature addresses transfer across a variety of populations and settings using a variety of approaches. Further work is required to establish a common approach to examining transfer in the CO-OP literature and the literature in general.

Development and pre-testing of a rehabilitation planning consultation for head-and-neck cancer

BACKGROUND

In contrast with other major chronic conditions such as heart disease and stroke, cancer care does not routinely integrate evidence-based rehabilitation services within the standard continuum. The objectives of the present project were to develop a rehabilitation planning consultation (rpc) for survivors of head-and-neck (hn) cancer, to test its feasibility, and to make refinements.

METHODS

Using intervention mapping, the rpc-alpha was developed by examining potential theoretical methods and practical applications relative to the program objectives. During feasibility testing, a single case series was conducted with survivors of hn cancer who had completed their cancer treatment within the preceding 11 months; iterative refinements were made after each case.

RESULTS

The rpc-alpha was led by a rehabilitation professional and was based on self-management principles. The initial consultation included instruction in a global cognitive strategy, goal-setting, introduction to available resources, action planning, and coping planning. A follow-up consultation was conducted a few weeks later. Of 9 participants recruited, 5 completed post-intervention assessments. Participants reported that the rpc helped them to make rehabilitation plans.

CONCLUSIONS

The rpc was feasible to use and satisfactory to a small group of hn cancer survivors. A pilot test of the refined version is in process.

Executive function, episodic memory, and Medicare expenditures

INTRODUCTION

We examined the relationship between health care expenditures and cognition, focusing on differences across cognitive systems defined by global cognition, executive function, or episodic memory.

METHODS

We used linear regression models to compare annual health expenditures by cognitive status in 8125 Nurses' Health Study participants who completed a cognitive battery and were enrolled in Medicare parts A and B.

RESULTS

Adjusting for demographics and comorbidity, executive impairment was associated with higher total annual expenditures of $1488 per person (P < .01) compared with those without impairment. No association for episodic memory impairment was found. Expenditures exhibited a linear relationship with executive function, but not episodic memory ($584 higher for every 1 standard deviation decrement in executive function; P < .01).

DISCUSSION

Impairment in executive function is specifically and linearly associated with higher health care expenditures. Focusing on management strategies that address early losses in executive function may be effective in reducing costly services.

Guided Training Relative to Direct Skill Training for Individuals With Cognitive Impairments After Stroke: A Pilot Randomized Trial

OBJECTIVE

To examine the effects of direct skill training and guided training for promoting independence after stroke.

DESIGN

Single-blind randomized pilot study.

SETTING

Inpatient rehabilitation facility.

PARTICIPANTS

Participants in inpatient rehabilitation with acute stroke and cognitive impairments (N=43).

INTERVENTIONS

Participants were randomized to receive direct skill training (n=22, 10 sessions as adjunct to usual inpatient rehabilitation) or guided training (n=21, same dose).

MAIN OUTCOME MEASURE

The FIM assessed independence at baseline, rehabilitation discharge, and months 3, 6, and 12.

RESULTS

Linear mixed models (random intercept, other effects fixed) revealed a significant intervention by time interaction (F_4,150=5.11, P<.001), a significant main effect of time (F_4,150=49.25, P<.001), and a significant effect of stroke severity (F_1,150=34.46, P<.001). There was no main effect of intervention (F_1,150=.07, P=.79). Change in FIM scores was greater for the direct group at rehabilitation discharge (effect size of between-group differences, d=.28) and greater for the guide group at months 3 (d=.16), 6 (d=.39), and 12 (d=.53). The difference between groups in mean 12-month change scores was 10.57 points.

CONCLUSIONS

Guided training, provided in addition to usual care, offered a small advantage in the recovery of independence, relative to direct skill training. Future studies examining guided training in combination with other potentially potent intervention elements may further advise best practices in rehabilitation for individuals with cognitive impairments after acute stroke.

The Cognitive Orientation to daily Occupational Performance (CO-OP): A scoping review

Background.

The Cognitive Orientation to daily Occupational Performance (CO-OP) approach—now trademarked as the CO-OPApproach—was introduced in the literature in 2001 as an intervention to improve real-world performance in children with developmental coordination disorder. CO-OP has since appeared in numerous publications and has seen adoption with various populations. No compilation of the CO-OP literature is available.

Purpose.

The purpose of this scoping review was to examine the extent (number) and nature (features and characteristics) of the literature on CO-OP.

Method.

Using the scoping review methodology outlined by Arksey and O’Malley, 10 online databases were searched for materials discussing CO-OP. Materials found were reviewed by two reviewers, independently. Articles were categorized according to identified study characteristics.

Findings.

In all, 94 documents were found, including 27 research articles examining application and adaptations of CO-OP with eight populations. In all cases, the approach was deemed useful; however, in many cases, adaptations to the CO-OP protocol were recommended.

Implications.

CO-OP has been applied with a number of populations. There is now sufficient research to warrant a systematic review of the research literature.

Comparison of two cognitive interventions for adults experiencing executive dysfunction post-stroke: a pilot study

Purpose This pilot partially randomised controlled trial compared the feasibility and preliminary efficacy of two promising interventions for persons with executive dysfunction post-stroke: (1) occupation-based strategy training using an adapted version of the Cognitive Orientation to daily Occupational Performance (CO-OP) approach; and (2) Computer-based EF training (COMPUTER training). Method Participants received 16 h of either CO-OP or COMPUTER training. We assessed feasibility and acceptability of each intervention, and change in intervention outcomes at baseline, post-intervention and one-month follow-up. Performance and satisfaction with performance in self-selected everyday life goals were measured by the participant and the significant other-rated Canadian Occupational Performance Measure (COPM). Other intervention outcomes included changes in EF impairment, participation in daily life and self-efficacy. Results Six participants received CO-OP and five received COMPUTER training: one in each group discontinued the intervention for medical reasons unrelated to the intervention. The remaining nine participants completed all 16 sessions. Participants expressed high levels of satisfaction with both interventions. Both treatment groups showed large improvements in self and significant other-rated performance and satisfaction with performance on their goals immediately post-intervention and at follow-up (CO-OP: effect sizes (ES) = 1.6-3.5; COMPUTER: ES = 0.9-4.0), with statistically significant within-group differences in CO-OP (p < 0.05). The COMPUTER group also showed large improvements in some areas of EF impairment targeted by the computerised tasks (ES = 0.9-1.6); the CO-OP group demonstrated large improvements in self-efficacy for performing everyday activities (ES = 1.5). Conclusions Our findings provide preliminary evidence supporting the feasibility of using both CO-OP and COMPUTER training with patients with executive dysfunction post-stroke. Implications for Rehabilitation Computerised executive function training and occupation-based strategy training are feasible to deliver and acceptable to persons with executive dysfunction post-stroke. Preliminary evidence suggests that both interventions have a positive impact on real-world outcomes; and, that CO-OP might have a greater impact on improving self-efficacy for performing everyday activities.
