Dynamic Occupational Therapy Cognitive Assessment (DOTCA-Ch) |
|
|
|
(Katz, Parush & Traub Bar-Ilan, 2005) The instrument was developed and researched at the Graduate Program, School of Occupational Therapy, of Hadassah and Hebrew University, Jerusalem, Israel. The DOTCA-Ch (based on the LOTCA) has been adapted for children ages 6-12 years, with an elaborate praxis area. A structured 5-step cueing system was added based on Toglia’s (1994) system in the TCA with her permission. The DOTCA-Ch battery consists of 22 subtests in 5 cognitive areas: orientation, spatial perception, praxis, visuomotor construction (including reaction time and immediate and delayed memory measures) and thinking operations. Each subtest has a base line score, a mediation score and a posttest score. The goals of the assessment are to identify the abilities and disabilities of the child in the different areas, to measure the learning potential and recognize the thinking strategies, through the use of a dynamic assessment. Standards of performance, cutoff scores and frequencies of dynamic scores of typical children are presented in the manual, as well as reliability and validity data related to children with learning disabilities, following brain-injuries and ADHD. Findings show the instrument to differentiate significantly between typical and disabled children. The instrument is available in English and Hebrew. Noomi Katz, PhD, OTR

Lowenstein Occupational Therapy Cognitive Assessment |
|
|
|
(Itzkovich, Averbuch, Elazar, & Katz, 2000) The LOTCA battery is used to assess adult persons with neurological deficits and mental health. It includes 25 subtests in 6 cognitive areas, orientation, visual and spatial perception, praxis, visuomotor organization and thinking operations. Scoring is on an ordinal scale of 1-4 (1-severe deficit and 4-average performance), except for orientation scores that range from 1-8, and categorization where the range is 1-5. Reliability, validity and standards of performance, for the LOTCA, are available for brain injured adult patients, patients following stroke, schizophrenic patients, healthy adults and healthy children (see references). The instrument is available in English, Spanish and Hebrew. Loewenstein Occupational Therapy Cognitive Assessment-Geriatric (LOTCA-G) (Itzkovich, Elazar, & Katz, 1996) The LOTCA-G is a version of the LOTCA battery for adults. The main changes relate to sensory motor deterioration in normal aging, therefore, items were enlarged, details were reduced, subtests were shorten so that the total time was reduced and memory subtests were added. The LOTCA-G includes 23 subtests in 7 cognitive areas, orientation, visual and spatial perception, praxis, visuomotor organization, thinking operations and memory. Scoring is on an ordinal scale of 1-4 (1-severe deficit and 4-average performance), except for orientation were scores range from 1-8. The test is a performance test with minimal verbal requirement except for orientation. Memory includes delayed recall and recognition. The test takes about 30-45 minutes to administer and total time is recorded. Construct validity was determined for the LOTCA-G comparing healthy elderly and patients following stroke as well as patients with dementia showing significant differences between the groups. Furthermore, taking into account also age related decline in cognitive function the battery was found to differentiate between healthy elderly and adults and those following stroke (Katz, Elazar, & Itzkovich, 1995; Bar Haim Erez & Katz, 2003). The instrument is available in English and Hebrew. Noomi Katz, PhD, OTR

The Cognitive Performance Test (CPT) |
|
|
|
By: Theressa Burns, OTR
The Cognitive Performance Test (CPT) is a standardized, performance-based assessment instrument, originally designed for the objective evaluation of function in Alzheimer’s Disease. The CPT is available for purchase through Maddack at: maddak.com . This instrument, based on Allen Cognitive Disability Theory, uses six common activities of daily living (ADL) tasks, for which the information-processing requirements can be systematically varied to assess ordinal levels of functional capacity. Six tasks, titled DRESS, SHOP, TOAST, PHONE, WASH and TRAVEL comprise the test. For each task, standard equipment, set-up and methods of administration are required. A gross level score is determined for each of the six tasks; these scores are then added for a total score and averaged (divided by 6) to determine the functional level and mode. The CPT was initially developed as a research instrument, to be used in longitudinal study of functional change and for serial assessment to detect change in response to a pharmacologic or environmental intervention. It currently serves as the functional assessment for the GRECC diagnostic work-up and has proved to be useful in the assessment of patients, with a variety of diagnoses, to predict and explain capabilities to function in various contexts.
