Engineering Virtuous health habits using Emotion and Neurocognition: Flexibility for Lifestyle Optimization and Weight management (EVEN FLOW)

Interventions to preserve functional independence in older adults are critically needed to optimize 'successful aging' among the large and increasing population of older adults in the United States. For most aging adults, the management of chronic diseases is the most common and impactful risk factor for loss of functional independence. Chronic disease management inherently involves the learning and adaptation of new behaviors, such as adopting or modifying physical activity habits and managing weight. Despite the importance of chronic disease management in older adults, vanishingly few individuals optimally manage their health behavior in the service of chronic disease stabilization to preserve functional independence. Contemporary conceptual models of chronic disease management and health habit theory suggest that this lack of optimal management may result from an underappreciated distinction within the health behavior literature: the behavioral domains critical for initiation of new behaviors (Initiation Phase) are largely distinct from those that facilitate their maintenance (Maintenance Phase). Psychological factors, particularly experiential acceptance and trait levels of openness are critical to engagement with new health behaviors, willingness to make difficult lifestyle changes, and the ability to tolerate aversive affective responses in the process. Cognitive factors, particularly executive function, are critical to learning new skills, using them effectively across different areas of life and contextual demands, and updating of skills to facilitate behavioral maintenance. Emerging data therefore suggests that individuals with greater executive function are better able to sustain behavior changes, which in turn protects against cognitive decline. In addition, social and structural supports of behavior change serve a critical buffering role across phases of behavior change. The present review attempts to address these gaps by proposing a novel biobehavioral intervention framework that incorporates both individual-level and social support system-level variables for the purpose of treatment tailoring. Our intervention framework triangulates on the central importance of self-regulatory functioning, proposing that both cognitive and psychological mechanisms ultimately influence an individuals' ability to engage in different aspects of self-management (individual level) in the service of maintaining independence. Importantly, the proposed linkages of cognitive and affective functioning align with emerging individual difference frameworks, suggesting that lower levels of cognitive and/or psychological flexibility represent an intermediate phenotype of risk. Individuals exhibiting self-regulatory lapses either due to the inability to regulate their emotional responses or due to the presence of executive functioning impairments are therefore the most likely to require assistance to preserve functional independence. In addition, these vulnerabilities will be more easily observable for individuals requiring greater complexity of self-management behavioral demands (e.g. complexity of medication regimen) and/or with lesser social support. Our proposed framework also intuits several distinct intervention pathways based on the profile of self-regulatory behaviors: we propose that individuals with intact affect regulation and impaired executive function will preferentially respond to 'top-down' training approaches (e.g., strategy and process work). Individuals with intact executive function and impaired affect regulation will respond to 'bottom-up' approaches (e.g., graded exposure). And individuals with impairments in both may require treatments targeting caregiving or structural supports, particularly in the context of elevated behavioral demands.

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.

Effectiveness of the Functional and Cognitive Occupational Therapy (FaCoT) Intervention for Improving Daily Functioning and Participation of Individuals with Mild Stroke: A Randomized Controlled Trial

BACKGROUND

Mild stroke can cause subtle cognitive-behavioral symptoms, which although might be hidden, can restrict community reintegration and participation. Cognitive rehabilitation programs exist for stroke but not specifically for mild stroke and the research evidence varies. The Functional and Cognitive Occupational Therapy (FaCoT) intervention was developed specifically for this population.

OBJECTIVE

To examine the effectiveness of FaCoT intervention for improving daily functioning and participation compared with standard care.

METHOD

A single blind randomized controlled trial with assessments pre (T1), post (T2) and 3-month follow-up (T3). Individuals in the FaCoT group received 10 weekly sessions practicing cognitive and behavioral strategies. The Canadian Occupational Performance Measure (COPM) was the primary outcome measure, IADL-questionnaire, Reintegration to Normal Living questionnaire (RNL) were secondary measures.

RESULTS

In total, 66 community-dwelling individuals with mild stroke were randomly allocated to FaCoT (n = 33, mean (SD) age 64.6 (8.2), 33% women), or control group (n = 33, mean (SD) age 64.4 (10.8), 45% women). Time X Group interaction effects were found for the COPM performance (F(1.4,90.3) = 11.75, p < 0.000) and satisfaction (F(1.5,96.8) = 15.70, p < 0.000), with large effect size values. Significant between-group effects were found for RNL (F = 10.02, p < 0.002, ɳP2 = 0.13). Most participants in FaCoT achieved a clinically important difference in COPM between T1-T2, T1-T3, and in RNL between T1 to T3 compared with the control group.

CONCLUSIONS

FaCoT intervention is effective to improve daily functioning, participation and satisfaction of individuals with mild stroke compared with standard care, therefore FaCoT should be implemented in community rehabilitation settings.

Using Multicontext Approach to Improve Instrumental Activities of Daily Living Performance after a Stroke: A Case Report

Cognitive deficits constitute one of the greatest challenges for independence achievement after a stroke. This paper provides an in depth view of the application of the Multicontext approach within routine Occupational Therapy care for a 41-year-old who demonstrated limited participation in activities of daily living as a consequence of executive function impairments and limited self-awareness. Results indicated improved online self-awareness, strategy use and functional performance, however, no changes were observed on a standard Awareness Questionnaire. This suggests that awareness within activities may be more important in contributing to effective strategy use and functional performance compared to verbal acknowledgment in an interview. Results also support the feasibility of the Multicontext approach within inpatient settings in Argentina.

Conceptualization of self-awareness in adults with acquired brain injury: A qualitative systematic review

Self-awareness is an important consideration in cognitive rehabilitation for clinicians working with individuals following acquired brain injury (ABI), with impaired self-awareness linked to poor outcomes. To appropriately target assessment and intervention for self-awareness, its theoretical foundation and definition must be considered. The aim was to identify the definitions, theoretical models and conceptual frameworks of self-awareness in adults with ABI, and how self-awareness is conceptualized within those models. A qualitative systematic review was completed using search terms related to descriptions of models/frameworks, ABI and self-awareness. Data were analysed by narrative synthesis. Thirty-five papers were included in the review. Within these, 13 models, 12 conceptual frameworks and 2 theories were described. The main themes and subthemes conceptualized in the synthesis were: Clinical presentation of self-awareness (classifications and dimensions of self-awareness), development of self-awareness (knowledge, feedback mechanisms, temporal aspects, self-evaluation, enablers, barriers), understanding (dys)function (cognitive processing mechanisms, neurological foundations, causal factors), and practice guidance (assessment and intervention). This review identified an extensive theoretical basis to support conceptualization of self-awareness following ABI, underpinned by a distinction between intellectual awareness, on-line awareness, and psychological denial. Clinical application of an evaluation process that includes these elements would be beneficial to inform the rehabilitation process.

Experiential Neurorehabilitation: A Neurological Therapy Based on the Enactive Paradigm

With the arrival of the cognitive paradigm during the latter half of the last century, the theoretical and scientific bases of neurorehabilitation have been linked to the knowledge developed in cognitive neuropsychology and cognitive neuroscience. Although the knowledge generated by these disciplines has made relevant contributions to neurological therapy, their theoretical premises may create limitations in therapeutic processes. The present manuscript has two main objectives: first, to explicitly set forth the theoretical bases of cognitive neurorehabilitation and critically analyze the repercussions that these premises have produced in clinical practice; and second, to propose the enactive paradigm to reinterpret perspectives on people with brain damage and their therapy (assessment and treatment). This analysis will show that (1) neurorehabilitation as a therapy underutilizes body-originated resources that aid in recovery from neurological sequelae (embrained therapy); (2) the therapeutic process is based exclusively on subpersonal explanation models (subpersonal therapy); and (3), neurorehabilitation does not take subjectivity of each person in their own recovery processes into account (anti-subjective therapy). Subsequently, and in order to attenuate or resolve the conception of embrained, subpersonal and anti-subjective therapy, I argue in support of incorporating the enactive paradigm in rehabilitation of neurological damage. It is proposed here under a new term, "experiential neurorehabilitation." This proposal approaches neurological disease and its sequelae as alterations in dynamic interaction between the body structure and the environment in which the meaning of the experience is also altered. Therefore, when a person is not able to walk, remember the past, communicate a thought, or maintain efficient self-care, their impairments are not only a product of an alteration in a specific cerebral area or within information processing; rather, the sequelae of their condition stem from alterations in the whole living system and its dynamics with the environment. The objective of experiential neurorehabilitation is the recovery of the singular and concrete experience of the person, composed of physical and subjective life attributes.

Cognitive strategy use in adults with acquired brain injury

Objective: Difficulty applying cognitive strategies during task performance is a hallmark feature of brain injury. This study aimed to develop a cognitive strategy profile of people living in a transitional living unit for people with brain injury.Research design: Prospective, longitudinal study (n = 16)Method: Cognitive strategy application was assessed using the Perceive, Recall, Plan, and Perform (PRPP) System of Task Analysis. Functional measures were also administered. Data were examined using Rasch analysis (FACETS 3.71.4) and relationships between variables were analyzed.Results: Rasch analysis of PRPP data generated a hierarchy of cognitive strategies: from the most complex executive processing strategies to the simplest perceptual and recall strategies. The functional profile revealed a more impaired group of clients than has been previously reported in similar residential programs. Cognitive strategy use (PRPP Total score) was correlated with functional independence (r = .61), the performance of instrumental activities of daily living (r = .45), and community participation (r = -.63).Conclusions: The PRPP System enabled assessment of cognitive strategy difficulties and generation of individual profiles that allowed for individualized intervention planning. More efficient and effective application of cognitive strategies was related to the improved functional performance of everyday tasks and activities, greater independence and community participation.

Establishing and measuring treatment fidelity of a complex cognitive rehabilitation intervention: The multicontext approach

Introduction

This article describes the process of establishing and measuring treatment fidelity of a complex cognitive rehabilitation intervention that uses a metacognitive strategy framework (the multicontext approach). We adapted treatment guidelines for use within an inpatient rehabilitation setting for people with acquired brain injury; explored training methods and therapist perspectives; developed and examined inter-rater reliability of a fidelity measure; and examined adherence to and proficiency of treatment methods.

Method

Therapist perspectives of the intervention and training were obtained from written questionnaires and reflections. Inter-rater reliability of 21 treatment components across 22 video-recorded treatment sessions was assessed by examining absolute agreement between two raters using Cohen’s kappa. The proportion of treatment components implemented in individual sessions as well as average proficiency ratings was calculated.

Results

The fidelity measure demonstrated good inter-rater agreement, ranging from 91–100% for treatment adherence and kappa of .77 to .94 for therapist proficiency. Adherence and proficiency varied between therapists but increased to nearly proficient levels with adjustments to training and procedures. Therapists highlighted the critical importance of video review as a training tool.

Conclusion

The fidelity measure provides a clinical tool for therapist self-reflection, supervision and training, as well as a tool for future research.

Associations between self-generated strategy use and MET-Home performance in adults with stroke

Self-generated strategy use has substantial potential for improving community living outcomes in adults with impaired executive function after stroke. However, little is known about how self-generated strategies support task performance in people with post-stroke executive function impairments living in the community. We explored strategy use among home-dwelling persons with stroke and neurologically-healthy control participants during the Multiple Errands Test-Home Version (MET-Home), a context-specific assessment with evidence of ecological validity designed to examine how post-stroke executive dysfunction manifests during task performance in the home environment. For persons with stroke, significant associations were identified between planning and tasks accurately completed on the MET-Home. Significant associations were also identified among the control participants for self-monitoring, multitasking, and "using the environment" strategies. These associations are related to enhanced MET-Home performance on sub-scores for levels of accuracy, passes, and total time. Rehabilitation interventions that focus on reinforcing self-generated strategy use may support community living outcomes in persons with post-stroke executive function impairments, but this area needs additional investigation.

Rehabilitation of emergent awareness of errors post traumatic brain injury: A pilot intervention

Impaired awareness of errors is common following traumatic brain injury (TBI) and can be a barrier to successful rehabilitation. The objective of this study was to develop and evaluate a computer-based intervention programme aimed at improving error awareness in individuals with TBI. A further aim was to explore its effects on metacognitive awareness and variability of performance. Participants were 11 individuals with TBI and impaired error awareness who performed a sustained attention task twice-weekly for four weeks. The intervention consisted of audio-visual feedback-on-errors during the sustained attention task. Six participants received audio-visual feedback-on-error, five did not receive feedback. Emergent and metacognitive awareness were measured pre- and post-intervention. Between-groups comparisons of emergent awareness from pre- to post-intervention showed that audio-visual feedback-on-error improved emergent awareness compared to no feedback-on-error. Some changes in metacognitive awareness of executive behaviours as a result of feedback were observed. Audio-visual feedback-on-error improved emergent awareness in individuals with TBI following a four-week/eight-session intervention. This improvement was not observed in the no-feedback group. This pilot intervention is not a stand-alone treatment but it has potential to be usefully incorporated into cognitive or clinical rehabilitation programmes to improve emergent awareness.

Analysis approaches and interventions with occupational performance

[Purpose] The purpose of this study was to analyze approaches and interventions with occupational performance in patients with stroke. [Subjects and Methods] In this study, articles published in the past 10 years were searched. The key terms used were “occupational performance AND stroke” and “occupational performance AND CVA”. A total 252 articles were identified, and 79 articles were selected. All interventions were classified according to their approaches according to 6 theories. All interventions were analyzed for frequency. [Results] Regarding the approaches, there were 25 articles for studies that provided high frequency interventions aimed at improving biomechanical approaches (31.6%). This included electrical stimulation therapy, robot therapy, and sensory stimulation training, as well as others. Analysis of the frequency of interventions revealed that the most commonly used interventions, which were used in 18 articles (22.8%), made use of the concept of constraint-induced therapy. [Conclusion] The results of this study suggest an approach for use in clinics for selecting an appropriate intervention for occupational performance.

A virtual shopping task for the assessment of executive functions: Validity for people with stroke

The importance of assessing executive functions (EF) using ecologically valid assessments has been discussed extensively. Due to the difficulty of carrying out such assessments in real-world settings on a regular basis, virtual reality has been proposed as a technique to provide complex functional tasks under a variety of differing conditions while measuring various aspects of performance and controlling for stimuli. The main goal of this study was to examine the discriminant, construct-convergent and ecological validity of the Adapted Four-Item Shopping Task, an assessment of the Instrumental Activity of Daily Living (IADL) of shopping. Nineteen people with stroke, aged 50-85 years, and 20 age- and gender-matched healthy participants performed the shopping task in both the SeeMe Virtual Interactive Shopping environment and a real shopping environment (the hospital cafeteria) in a counterbalanced order. The shopping task outcomes were compared to clinical measures of EF. The findings provided good initial support for the validity of the Adapted Four-Item Shopping Task as an IADL assessment that requires the use of EF for people with stroke. Further studies should examine this task with a larger sample of people with stroke as well as with other populations who have deficits in EF.

Executive functioning: a scoping review of the occupational therapy literature

BACKGROUND

Increasingly recognized as an important factor in the performance of complex, goal-directed tasks, executive functioning is understood in different ways across disciplines.

PURPOSE

The aim was to explore the ways in which executive functioning is conceptualized, discussed, described, and implied in the occupational therapy literature.

METHOD

A scoping review of the occupational therapy literature was conducted following Levac, Colquhoun, and O'Brien's (2010) recommended methodology.

RESULTS

Executive functioning is described both as a set of performance component skills or processes and as the executive occupational performance inherent in complex occupations. Executive functioning is implicit in occupational performance and engagement, and some health conditions seem to be commonly associated with impaired executive functioning. Assessing executive functioning requires dynamic occupation- and performance-based assessment. Interventions targeting executive functioning are grounded in metacognitive approaches.

CONCLUSION

Executive functioning is a complex construct that is conceptualized with considerable variance within the occupational therapy literature, creating barriers to effective service delivery.

Anatomy of Cognitive Strategies: A Therapist's Primer for Enabling Occupational Performance

Background. Promoting effective strategy use is an integral part of enabling occupational performance; however, there are variations in how strategies are defined, discussed, used, and applied in occupational therapy practice.Purpose. Focusing on cognitive strategies, in this paper, we define and describe strategies and their types and divide the concept of strategies into two dimensions: strategy attributes and strategy use. A comprehensive framework for each dimension (attribute and use) is proposed as a clinical reasoning guide as well as a foundation for future research. The frameworks are designed to reduce ambiguity, deepen understanding, and serve as clinical reasoning guides assisting therapists in specifying, describing, and observing cognitive strategies during occupational performance.Key Issues. We argue that there is a need for therapists to use consistent terminology and to be able to systematically select cognitive strategies and evaluate their use.Implications. The proposed strategy frameworks provide clinical guides for systematic analysis and selection of cognitive strategies as well as for observing components of strategy use during clients' occupational performance. We suggest the need for greater specification and description of strategies during intervention and highlight directions for future research.
