This study examined the reliability and validity of the Executive Function Performance Test (EFPT). The EFPT assesses executive function deficits in the performance of real-world tasks. It uses a structured cueing and scoring system to assess higher-level cognitive functions, specifically initiation, organization, sequencing safety and judgment, and task completion. Seventy-three participants with mild to moderate stroke and 22 age- and education-matched controls completed the 4 EFPT tasks (cooking, using the telephone, managing medications, and paying bills). Significant differences were found between participants with mild and moderate stroke and healthy control participants. The EFPT can help occupational therapists determine the level of support needed by people with cognitive impairments to perform complex instrumental tasks. Objective information derived from this assessment is an essential part of the process of determining whether the person can live independently and helping families understand how to support the performance of their family members at home.

Stroke is one of the most life-altering syndromes affecting the world population. Rehabilitation for people experiencing stroke is focused almost exclusively on self-care activities and being able to return home and has little to no focus on work rehabilitation or community reintegration. The Cognitive Rehabilitation Research Group (CRRG) at the Washington University School of Medicine in St. Louis was formed with the vision of improving everyday life for people after stroke by translating knowledge from neuroscience into treatment programs for productive living. Descriptive analysis of the intake assessment from the CRRG Clinical Core (N = 7,740) revealed three important findings: The age at stroke is decreasing, most strokes are neurologically mild to moderate in nature, and discharge placement decisions are being made largely on the basis of measures of impairment. The changes in the stroke population require occupational therapy to expand rehabilitation beyond the acute management of stroke to address full participation in work, family, and community life.

Many acute stroke patients had cognitive and perceptual deficits that were not documented in their charts. These data support the Post-Stroke Rehabilitation Guidelines for systematic assessment even when deficits are not immediately apparent. Systematic screening may improve discharge planning, rehabilitation treatment, and long-term outcome of persons with stroke.

The Kitchen Task Assessment (KTA) is a functional measure that records the level of cognitive support required by a person with Senile Dementia of the Alzheimer's Type (SDAT) to complete a cooking task successfully. The results allow the clinician to help caregivers understand the level of support the impaired person needs to perform daily living tasks. This paper presents the validity and internal consistency of the KTA. Data were collected from 106 persons diagnosed with SDAT. Construct validity was established by examining the relationship between subjects' performance on the KTA and standard neuropsychological measures.

Purpose The purpose of this study was to estimate the effect of the Cognitive Orientation to daily Occupational Performance (CO-OP) approach compared to usual outpatient rehabilitation on activity and participation in people less than 3 months post stroke. Methods An exploratory, single blind, randomized controlled trial with a usual care control arm was conducted. Participants referred to 2 stroke rehabilitation outpatient programs were randomized to receive either Usual Care or CO-OP. The primary outcome was actual performance of trained and untrained self-selected activities, measured using the Performance Quality Rating Scale (PQRS). Additional outcomes included the Canadian Occupational Performance Measure (COPM), the Stroke Impact Scale Participation Domain, the Community Participation Index, and the Self Efficacy Gauge. Results Thirty-five (35) eligible participants were randomized; 26 completed the intervention. Post-intervention, PQRS change scores demonstrated CO-OP had a medium effect over Usual Care on trained self-selected activities (d=0.5) and a large effect on untrained (d=1.2). At a 3 month follow-up, PQRS change scores indicated a large effect of CO-OP on both trained (d=1.6) and untrained activities (d=1.1). CO-OP had a small effect on COPM and a medium effect on the Community Participation Index perceived control and the Self-Efficacy Gauge. Conclusion CO-OP was associated with a large treatment effect on follow up performances of self-selected activities, and demonstrated transfer to untrained activities. A larger trial is warranted.

Attaining and demonstrating treatment fidelity is critical in the development and testing of evidence-based interventions. Treatment fidelity refers to the extent to which an intervention was implemented in clinical testing as it was conceptualized and is clearly differentiable from control or standard-of-care interventions. In clinical research treatment fidelity is typically attained by intensive training and supervision techniques and demonstrated by measuring therapist adherence and competence to the protocol using external raters. Yet, in occupational therapy (OT) and physical therapy (PT) outcomes research, treatment fidelity methods have not been utilized, which in our view is a serious gap that impedes novel treatment development and testing in these rehabilitation fields. In this article we describe the development of methods to train and supervise therapists to attain adequate treatment fidelity in a treatment development project involving a novel OT and PT-based intervention. We also present a data-driven model for demonstrating therapist adherence and competence in the new treatment and its differentiation from standard-of-care. In doing so, we provide an approach that rehabilitation researchers can use to address treatment fidelity in OT and PT-based interventions. We recommend that all treatment researchers in rehabilitation disciplines use these or similar methods as a vital step in development and testing of evidence-based rehabilitation interventions.
