Impaired Performance on a Cognitively-Based Instrumental Activities of Daily Living Task, the 10-Item Weekly Calendar Planning Activity, in Individuals With Stroke Undergoing Acute Inpatient Rehabilitation

Validity of the Short Weekly Calendar Planning Activity in patients with Parkinson disease and nonmanifesting LRRK2 and GBA carriers

BACKGROUND AND PURPOSE

Subtle executive dysfunction is common in people newly diagnosed with Parkinson disease (PD), even when general cognitive abilities are intact. This study examined the Short Weekly Calendar Planning Activity (WCPA-10)'s known-group construct validity, comparing persons with PD to healthy controls (HCs) and nonmanifesting carriers of LRRK2 and GBA gene mutations to HCs. Additionally, convergent and ecological validity was examined.

METHODS

The study included 73 participants: 22 with idiopathic PD (iPD) who do not carry any of the founder GBA mutations or LRRK2-G2019S, 29 nonmanifesting carriers of the G2019S-LRRK2 (n = 14) and GBA (n = 15) mutations, and 22 HCs. Known-group validity was determined using the WCPA-10, convergent validity by also using the Montreal Cognitive Assessment (MoCA) and Color Trails Test (CTT), and ecological validity by using the WCPA-10, Schwab and England Activities of Daily Living Scale (SE ADL), and Physical Activity Scale for the Elderly (PASE).

RESULTS

Known-group validity of the WCPA-10 was established for the iPD group only; they followed fewer rules (p = 0.020), were slower (p = 0.003) and less efficient (p = 0.001), used more strategies (p = 0.017) on the WCPA-10, and achieved significantly lower CTT scores (p < 0.001) than the HCs. The nonmanifesting carriers and HCs were similar on all cognitive tests. Convergent and ecological validity of the WCPA-10 were partially established, with few correlations between WCPA-10 outcome measures and the MoCA (r = 0.50, r = 0.41), CTT-2 (r = 0.43), SE ADL (r = 0.41), and PASE (r = 0.54, r = 0.46, r = 0.31).

CONCLUSIONS

This study affirms the known-group validity for most (four) WCPA-10 scores and partially confirms its convergent and ecological validity for PD.

Validity of the Chinese version of the weekly calendar planning activity (WCPA) on assessing executive function in adults with stroke

The weekly calendar planning activity (WCPA) is a performance-based assessment of executive function (EF) via a cognitively-based instrumental activity of daily life (C-IADL). This study aimed to examine the validity of the Chinese version of the WCPA in adults with stroke and to explore the characteristics of cognitive strategy use among the population. Fifty-eight hospitalized patients with stroke aged 26-82 years and 53 controls completed the WCPA, two neuropsychological tests and instrumental activity of daily life (IADL) scale. Participants with stroke were subdivided into a stroke cognitive impaired group (Stroke-CI) and a general stroke group (Stroke-NCI) based on the Montreal Cognitive Assessment. Results showed that the WCPA was able to discriminate between Stroke-CI with controls and the Stroke-NCI group with controls. We found significant limitations in stroke patients' ability to use strategies. Concurrent and ecological validities were demonstrated through correlations between the neuropsychological test scores, IADL and the WCPA performance. This study provides initial evidence for the validity of the Chinese version of the WCPA-10 for adults with stroke and suggests the need to use performance-based tests even in patients with normal cognitive screening test results. The WCPA could provide useful information for strategy-based interventions for adults with stroke.

Loss-of-Set and Strategy Application on the Menu Task: An Exploratory Study

Background. The Menu Task (MT) is an occupational therapy screening measure designed to identify people in need of functional cognitive (FC) assessment. Purpose. To explore whether test-taker strategy selection on the MT is clinically informative. Methods. Using a cross-sectional design we administered assessments of FC including the MT and the After MT interview, cognitive screening measures, and self-report instrumental activities of daily living assessment to a convenience sample of 55 community-dwelling adults. After MT interviews responses were qualitatively characterized as (a) loss of set (e.g., not recognizing that food preferences are irrelevant to task performance), (b) calorie counting, or (c) planning. Findings. Loss of set was associated with poorer performance on most study measures, calorie counting was associated with superior performance on most study measures, and no differences were observed relating to planning. Implications. Determining the test-takers approach to the MT adds information to that provided by the MT itself.

Translation, cross-cultural adaptation and validation of the 10-item Weekly Calendar Planning Activity in Spanish-speaking ABI patients: a multicenter study

We present the process of translation, adaptation, and validation in the Spanish context of the 10-item version of the Weekly Calendar Planning Activity (WCPA-10), a performance-based measure of cognitive instrumental activities of daily living (C-IADL). The study consisted of two phases: I) translation/cultural adaptation of the WCPA, conducted by professional bilingual translators, a panel of experts, and a pilot study, and II) validation in a sample of 42 acquired brain injury patients (ABI) and 42 healthy participants (HC). WCPA primary outcomes showed expected convergent/discriminant validity patterns with socio-demographical and clinical variables and cognitive processes identifying those WCPA outcomes that best predicted executive and memory deficits measured with a battery of traditional neuropsychological tests. In addition, performance on the WCPA was a significant predictor of everyday functioning over variables such as socio-demographics or global cognition when measured with traditional tests. External validity was established by the WCPA's ability to identify everyday cognitive deficits in ABI patients compared to HC, even in those with subtle cognitive impairment based on neuropsychological tests. The Spanish WCPA-10 seems an appropriate and sensitive assessment tool to identify cognitive-functional impairment in ABI-patients, even those with subtle cognitive impairment. The results also highlight the relevance of this kind of test, as they indicate a better prediction of patients' real-world functioning than traditional neuropsychological tests.

The Weekly Calendar Planning Activity to Assess Functional Cognition in Parkinson Disease

The Weekly Calendar Planning Activity (WCPA) may improve understanding of functional cognition in people with Parkinson disease (PwPD) without dementia. We aimed to determine if WCPA performance (a) discriminates between PwPD with and without cognitive impairment and healthy controls and (b) correlates with other indicators of cognition and daily function. This was a cross-sectional study. Parkinson disease (PD) participants without dementia were divided into normal cognition (PD-NC, n = 25) and possible mild cognitive impairment (PD-MCI, n = 21) groups. Their WCPA performance was compared with that of a normative sample (n = 196) and correlated with neuropsychological test performance and self-reported cognition and participation. Both the PD-MCI and PD-NC groups had impaired WCPA performance. WCPA performance correlated with executive function, processing speed, and self-reported cognition and participation. The WCPA can detect functional cognitive deficits in PwPD without dementia and can inform occupational therapy interventions to support functional cognition, occupational performance, and participation in this population.

Methodological Issues in Advancing the Status of Functional Cognitive Assessment

Many individuals in acute hospital and post-acute care settings experience changes in their capacity to perform complex activities of daily living associated with deficits in functional cognition. Occupational therapists regularly assess and treat these occupational performance deficits. The construct of functional cognition offers oportunities for occupational therapists to define an approach to cognition that is both distinct from that of other disciplines and that supports evidence-based interventions. This article provides a rationale for performance-based assessment of functional cognition and an overview of the methodological issues associated with the development and implementation of reliable and valid screening and comprehensive asseements of functional.

Further Validation of the Menu Task: Functional Cognition Screening for Older Adults

Occupational therapists need a brief tool to identify the potential for functional cognitive deficits leading to impaired occupational performance. The objective is to establish the sensitivity and specificity, concurrent and known-group validity of the Menu Task by comparison with performance on the Weekly Calendar Planning Activity (WCPA). Using a cross-sectional design, we administered the Menu Task and the WCPA to a community-dwelling convenience sample of 287 adults aged from 55 to 93 years. The receiver operating characteristic (ROC) analysis estimated sensitivity and specificity. Concurrent and known-group construct validity was examined by comparing scores on the Menu Task with the WCPA scores. As a result, a new cutoff score of 9 was established for the Menu Task (area under the curve [AUC] = 0.80, sensitivity = 0.89, 95% confidence interval [CI] = [0.73, 0.97]; specificity = 0.58, 95% CI = [0.52, 0.64]). Both concurrent and construct validity were supported. The Menu Task demonstrates sensitivity to functional cognitive impairments in a community sample.

Online awareness of performance on a functional cognitive assessment in individuals with stroke: A case-control study

Unawareness is a significant barrier to cognitive rehabilitation following acquired brain injury. Little is known about online awareness of cognitively-based instrumental activities of daily living (C-IADL) after stroke, particularly C-IADLs that emphasize executive functions. Our goal was to evaluate in stroke patients (1) online awareness during and immediately after a C-IADL task that emphasizes executive functions and (2) the association between awareness and performance on the C-IADL task. Seventy-seven stroke patients on an acute inpatient rehabilitation unit and 77 control participants completed the 10-item Weekly Calendar Planning Activity (WCPA-10), a standardized C-IADL task that requires working memory, planning, shifting, and inhibition. Trained examiners observed the use of a self-checking strategy and self-recognition of errors during the task. Immediately after the task, participants estimated their accuracy, and rated their own performance, which was compared with objective accuracy. Relative to the control group, stroke patients overestimated their accuracy, less often recognized errors, and less frequently used a self-checking strategy. Overestimation was associated with worse overall performance on the WCPA-10. Findings suggest that poor online awareness of C-IADL performance is common in stroke patients undergoing acute inpatient rehabilitation. Increasing awareness through metacognitive interventions should be a core focus of early post-stroke cognitive rehabilitation.

Awareness of Performance on a Functional Cognitive Performance-Based Assessment Across the Adult Lifespan

As people age, their cognitive skills and ability to complete complex instrumental activities of daily living often decline in subtle ways. Older adults who are aware of these slight cognitive and functional changes spontaneously adapt and implement strategies to maximize performance. On the other hand, older adults with limited self-awareness are less likely to adjust performance or initiate compensatory strategies as they may not recognize the need to do so. This places them at higher risk of functional decline and loss of independence. Research on awareness of functional performance in healthy adults is, however, limited, and there is a paucity of assessment tools available to address questions of awareness and strategy use in functional tasks. We used the Weekly Calendar Planning Activity (WCPA) - a performance-based assessment of functional cognition including measures of awareness and strategy use - to investigate differences in performance, awareness, and strategy use across the adult lifespan. The WCPA requires examinees to schedule appointments into a weekly calendar while following rules designed to increase task demands. Healthy adults (n=342) from ages 18-92 were observed for strategy use and error recognition, while a post-test interview probed participants' reported strategy use and estimation of accuracy. The discrepancy between participant estimation and actual accuracy provided a measure of online awareness of performance where a larger estimation discrepancy indicated over-estimation of performance. Performance on the WCPA declined across the adult lifespan. Older adults were less likely to use self-monitoring strategies and used less effective strategies overall. Overestimation was associated with use of fewer strategies and lower accuracy in all age groups. Importantly, twice as many older adults overestimated compared to younger adults. Furthermore, the subset of older adults who had good awareness of performance was more likely to use effective strategies, to recognize errors, and achieved accuracy on par with their younger counterparts. Our results emphasize the importance of examining self-awareness of performance and analyzing the strategies used to perform a complex functional task. This information can provide a foundation for early detection of functional decline in aging and for designing interventions to maximize functional independence in aging.
