Validity of the Árnadóttir OT-ADL Neurobehavioral Evaluation (A-ONE): Performance in Activities of Daily Living and Neurobehavioral Impairments of Persons With Left and Right Hemisphere Damage

Occupational therapy assessment and treatment of visual perceptual impairments are integral to the rehabilitation of clients following stroke and other acquired brain injuries. Occupational therapists need to identify the nature of visual perceptual performance impairments in order to choose rehabilitation intervention strategies appropriate for remediation of specific problems or to compensate for limitations in daily function. This paper describes the variations in visual perception terminology and occupational therapy approaches to visual perceptual assessment. Limitations of existing assessment tools for visual perception are highlighted in terms of reliability, validity, normative information, length of time to administer, and comprehensiveness in screening for visual perceptual impairment. In response to these limitations, a battery of items, called the Occupational Therapy Adult Perceptual Screening Test (OT-APST) was selected to screen adults comprehensively for impairments of agnosia, visuospatial skills including body scheme and neglect, constructional skills, apraxia, and acalculia. It also includes a subtest to evaluate functional skills directly observed during screening. This new battery has established reliability, validity and age-stratified normative data for adults 16 to 97 years of age. The OT-APST is recommended for use in conjunction with observational assessment of activities of daily living for clients with stroke and acquired brain injury.

“…There is increasing pressure on all health professionals, including occupational therapists, to use assessment tools that are standardized, reliable, quantifiable, and valid to determine the level of function or dysfunction of clients, and to measure the efficiency and effectiveness of treatment (11,14,30).…”

Construct and ecological validity of the Occupational Therapy Adult Perceptual Screening Test (OT-APST)

et al. 2006

This paper reports on the construct validity (scale design and convergent validity) and ecological validity of the Occupational Therapy Adult Perceptual Screening Test (OT-APST). The performance of 208 participants following stroke on the OT-APST and a reference tool (either the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) or the LOTCA-Geriatric version (LOTCA-G)) was compared. The OT-APST performance of the stroke sample was compared with a healthy normative sample (n = 356). The relationship between the OT-APST performance and the Functional Independence Measure (FIM) score of the participants following stroke was also examined. Factor analysis and internal consistency results supported the scale design of the OT-APST. Significant correlations between the performance of the participants following stroke on the OT-APST and the reference tool supported the convergent validity of the OT-APST. The ability of the OT-APST to separate the two participant groups provided further evidence of its construct validity. Significant correlations between OT-APST and FIM scores supported the ecological validity of this tool. This study shows that the OT-APST is an ecologically valid tool with demonstrated construct validity in the assessment of visual perception.

“…This process includes, for example, consideration of the pattern of observed impairments, knowledge of central nervous system processing sites (e.g. visuospatial functions), and consideration of which NB impairments were observed in other ADL tasks (22,23). Therapists are trained in the reasoning process during five-day training courses.…”
