The concept of functional cognition has been variously defined, but at its core relates to how cognitive and performance abilities are integrated and used in everyday life. Functional cognition is a fundamental element of occupational performance, and functional cognitive assessment and intervention are central to how occupational therapy can improve client outcomes. Attendees at a conference convened by the American Occupational Therapy Foundation identified areas where the construct of functional cognition required further clarification.

Article Synopsis
  • This study investigates how awareness of performance difficulties affects community-dwelling adults' abilities in managing tasks related to daily living, using specific assessments like the WCPA-17 and PCST.
  • A cross-sectional analysis of 274 adults aged 55 to 93 years was conducted, comparing those who displayed awareness of their difficulties to those who did not.
  • The results indicated that individuals with awareness generally performed better across all measures, suggesting that maintaining awareness is crucial for effectively handling complex daily activities.

Background: Early identification of subtle cognitive decline in community-dwelling older adults is critical, as mild cognitive impairment contributes to disability and can be a precursor to dementia. The clock drawing test (CDT) is a widely adopted cognitive screening measure for dementia, however, the reliability and validity of paper-and-pencil CDT scoring scales for mild cognitive impairment in community samples of older adults is less well established. We examined the reliability, sensitivity and specificity, and construct validity of two free-drawn clock drawing test scales-the Rouleau System and the Clock Drawing Interpretation Scale (CDIS)-for subtle cognitive decline in community-dwelling older adults.

The Menu Task (MT) is an occupational therapy screening measure designed to identify people in need of functional cognitive (FC) assessment. To explore whether test-taker strategy selection on the MT is clinically informative. 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.

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.

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.

Occupational therapy's focus on functional cognition offers a distinct approach to the assessment of and intervention for occupational performance deficits that may follow coronavirus disease 2019 (COVID-19). Although the majority of people survive COVID-19, many people experience persistent functional cognitive sequelae severe enough to interfere with occupational performance. After COVID-19, people may be categorized as either (1) those who experience severe or critical illness requiring hospitalization or (2) those with mild to moderate presentations of the virus without hospitalization.

Identification of functional cognitive deficits can facilitate intervention to improve outcomes among older adults. We aimed to determine if impairments on screening tests of cognition are associated with deficits in performance on a more extensive functional cognitive assessment. Using a cross-sectional study design we administered the Montreal Cognitive Assessment (MoCA), the Mini-Cog, the Menu Task, and Weekly Calendar Planning Activity (WCPA) to a convenience sample of 277 community-dwelling older adults (55-93 years old).

Purpose: Goal achievement relies heavily on executive functions, which may be compromised following mild traumatic brain injury (mTBI). Implementation intentions (II) have been found to help people act in accordance with their goals. II are written statements that describe a behavior that a person plans to enact when they encounter some form of anticipated trigger or stimulus.

The identification of functional performance deficits is critical to the community independence of older adults. We examined whether a combined cognitive and performance-based medication management measure would be able to better classify an individual's functional cognitive status and potential for instrumental activities of daily living (IADL) impairment than either measure alone. Community-dwelling adults age 55 and older ( = 185) were administered the Mini-Cog, the Medication Transfer Screen-Revised (MTS-R), a combination measure the Medi-Cog-Revised (Medi-Cog-R), the Performance Assessment of Self-Care Skills (PASS) Checkbook Balancing and Shopping tasks (PCST), additional cognitive screening measures, and a self-report daily living scale.

Functional cognition is a critical domain of concern for occupational therapy practice. As the health care system moves to assessing value through achievement of quality outcomes, the field of occupational therapy must address the inclusion of functional cognition in evaluation and treatment. Evidence indicates that impaired cognition contributes to risk of hospital readmission and poor overall health outcomes across diagnostic groups.

Age at first stroke is decreasing, and most strokes are mild to moderate in severity. Executive function (EF) deficits are increasingly recognized in the stroke population, but occupational therapists have not altered their evaluation methods to fully accommodate changing patient needs. We present a hierarchical performance-based testing (PBT) pathway using data to illustrate how PBT could identify patients with mild stroke-related EF deficits in need of occupational therapy intervention.
