    Comparing the CO-OP ApproachTM to Usual Occupational Therapy for Adults with Executive Dysfunction Following Acquired Brain Injury: A Randomized Controlled Trial

    by Deirdre R. Dawson, Nicole D. Anderson, Yael Bar, Malcolm A. Binns, Adora Chui, Anne W. Hunt, Emily Nalder, Merrick Zwarenstein

    Impairments of executive function following acquired brain injury including stroke (ABI) contribute significantly to long-lasting everyday difficulties in life. Pilot work on the CO-OP ApproachTM (Cognitive Orientation to daily Occupational Performance Approach), a contextualized strategy training intervention, with ABI adults with executive dysfunction showed improved performance on untrained everyday life tasks and cognitive flexibility. Objective: Our objective was to determine the efficacy of the CO-OP Approach relative to usual occupational therapy (UOT) for community-dwelling adult survivors of ABI with executive dysfunction. Methods: Eighty-seven participants were randomized to receive CO-OP (n = 45) or UOT (n = 42) in their homes. All participants identified five personally meaningful, everyday life goals (using the Canadian Occupational Performance Measure (COPM)) and received up to 15 one-hour treatment sessions twice per week. Three goals were trained, and two were untrained. Interventions were provided by occupational therapists registered with their regulatory college. The CO-OP group was trained to apply a meta-cognitive strategy to three goals. The UOT group received therapy based on the clinicians’ (experienced in community settings) determination. Testers were masked to the participants’ group. Analysis at the primary outcome (Post-test, ~10 weeks following baseline) was on an intent-to-treat basis. Results: Participants in the CO-OP group had a mean age of 57.5 years, a mean time post-ABI of 5.3 years, and were 57.8% men. Those in the usual OT group had a mean age of 54.7 years, a mean time post-ABI of 6.2 years, and were 69.0% men. The CO-OP group reported statistically significant higher improvements on COPM performance and satisfaction scores post-test for untrained and trained goals. However, these benefits were not retained at follow-up (three months post-baseline). Conclusions: The CO-OP ApproachTM shows promise for improving performance in everyday life goals for individuals with chronic ABI relative to usual community occupational therapy. Achieving retention of these benefits remains a challenge.

    Mobile Technology–Based Interventions for Stroke Self-Management Support: Scoping Review

    by Alexandra N Thompson, Deirdre R Dawson, Jean Michelle Legasto-Mulvale, Nivetha Chandran, Chelsea Tanchip, Veronika Niemczyk, Jillian Rashkovan, Saisa Jeyakumar, Rosalie H Wang, Jill I Cameron, et al.

    Background: There is growing interest in enhancing stroke self-management support using mobile health (mHealth) technology (eg, smartphones and apps). Despite this growing interest, “self-management support” is inconsistently defined and applied in the poststroke mHealth intervention literature, which limits efforts to synthesize and compare evidence. To address this gap in conceptual clarity, a scoping review was conducted. Objective: The objectives were to (1) identify and describe the types of poststroke mHealth interventions evaluated using a randomized controlled trial design, (2) determine whether (and how) such interventions align with well-accepted conceptualizations of self-management support (the theory by Lorig and Holman and the Practical Reviews in Self-Management Support [PRISMS] taxonomy by Pearce and colleagues), and (3) identify the mHealth functions that facilitate self-management. Methods: A scoping review was conducted according to the methodology by Arksey and O’Malley and Levac et al. In total, 7 databases were searched. Article screening and data extraction were performed by 2 reviewers. The data were analyzed using descriptive statistics and content analysis. Results: A total of 29 studies (26 interventions) were included. The interventions addressed 7 focal areas (physical exercise, risk factor management, linguistic exercise, activities of daily living training, medication adherence, stroke education, and weight management), 5 types of mobile devices (mobile phones or smartphones, tablets, wearable sensors, wireless monitoring devices, and laptops), and 7 mHealth functions (educating, communicating, goal setting, monitoring, providing feedback, reminding, and motivating). Collectively, the interventions aligned well with the concept of self-management support. However, on an individual basis (per intervention), the alignment was less strong. Conclusions: On the basis of the results, it is recommended that future research on poststroke mHealth interventions be more theoretically driven, more multidisciplinary, and larger in scale.

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

    by Deirdre R. Dawson, Yael Bar, Fatim Ajwani, Shlomit Rotenberg, Barbara Atlas, Maria Ricupero, Carol Greewood, Matthew D. Parrott

    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.

    Known-Groups and Convergent Validity of the Telephone Rey Auditory Verbal Learning Test total Learning Scores for Distinguishing Between Older Adults With Amnestic Cognitive Impairment and Subjective Cognitive Decline

    by Shreya Jagtap, Deirdre R Dawson, Susan Vandermorris, Nicole D Anderson, Naomi Davids-Brumer, Mishal Dar, Alana Bernick, Shlomit Rotenberg

    To examine known-groups validity of a telephone administration of the total learning scores of the Rey Auditory Verbal Learning Test (RAVLT) in discriminating between people with subjective cognitive decline (SCD) and amnestic mild cognitive impairment (aMCI) and convergent validity of the telephone-RAVLT. In total, 83 older adults (age = 71.4 ± 7.0) with SCD or aMCI completed the RAVLT learning trials over the telephone and the Hopkins Verbal Learning Test (HVLT) in-person. Telephone-RAVLT total recall significantly correlated with HVLT total recall (r = .49, p < .001). Significant between group differences were found (effect size = 0.94). This study provides support for known-groups and convergent validity of the telephone-RAVLT.

    Developing and Validating a Big-Store Multiple Errands Test

    by Kristen Antoniak, Julie Clores, Danielle Jensen, Emily Nalder, Shlomit Rotenberg, Deirdre R. Dawson

    The Multiple Errands Test (MET) is an ecologically valid assessment that characterizes how executive dysfunction manifests in everyday activities. Due to the naturalistic nature of this assessment, clinicians and researchers have had to develop site-specific versions resulting in numerous published versions and making it difficult to establish standard psychometric properties. The aim of this study was to develop a standardized, community version of the MET designed to be used in large department stores meeting set criteria that would not require site specific modifications. This paper reports on the development, content validity, feasibility, and inter-rater reliability of a Big-Store MET, and the performance of healthy participants on this test. Items were selected to match previously published versions in relation to quantity and complexity. Content validity was established by having experts (n = 4) on the MET review the proposed Big-Store version and evaluate the task consistency with previously published versions. To assess feasibility of administration, and inter-rater reliability, a convenience sample of 14 community dwelling adults, self-reporting as healthy, were assessed by two trained raters. We found the Big-Store MET to be feasible to deliver (completed within 30 min, scores show variability, acceptable to participants in community environment) and inter-rater reliability to be very high (ICCs = 0.92–0.99) with the exception of frequency of strategy use. This study introduces the Big-Store MET to the literature, establishes its preliminary validity and reliability thus laying the foundation for a standardized, community-based version of the MET.
