The test consists of three visual motor learning tasks stitching leather with increased complexity in the activities. There is barely any convergence in measures with memory and executive function tests.

The criteria for exclusion were having previously suffered any type of cognirive damagepresenting some type of psychotic process in an active phase at the time of the initial assessmentor presenting any condition that would prevent the proper comprehension of the instructions used to complete the tests such as language issues, illiteracy, and a state of confusion.

The comparisons between subgroups loewehstein made using nonparametric procedures. The test was applied with satisfactory results on subjects being treated for substance addiction and evidence was found of convergent validity with neuropsychology tests [ 32 ].

The test has been used in a large number of studies and its psychometric properties have proven satisfactory in many research projects and in very diverse populations and geographic areas. Specifically, LOTCA does not seem to measure something related to executive functions given that it barely shows convergence in measurements with the 5-Digit Test. Recommendations for Further Research.

Specifically, the following were administered in accordance with the standards found in each manual: In order to complete the three tasks successfully, the person must pay attention to the verbal instructions and demonstration, understand and use sensory signals from the materials leather, lace, and needlesand effectively use feedback from the motor actions during practice with the lacing materials. A comprehensive review found that certain cognitive deficits represent common addictive processes elements deficits in episodic memory, emotional processing, and the executive components of updating and decision-makingwhile others are specifically associated with each substance psychostimulants and alcohol use with impulsive action and cognitive flexibility, alcohol and MDMA with spatial processing, perceptual speed and selective attention, cannabis and methamphetamine on prospective memory deficits, and cannabis and MDMA on processing speed and complex planning [ 9 ].


Loewenstein Occupational Therapy Cognitive Assessment to Evaluate People with Addictions

There were significant differences in relation to the education level of the participants: However, the difference in the time used by men and women to complete the test was significant: You will receive an email whenever this article is corrected, updated, or cited in the literature.

New studies are needed to contribute more information on its potential and on the rest of the tests which must be used to supplement its use in order to provide a full occupational assessment that is adequate for people in rehabilitation processes for their addictive behaviors.

According to a recent review, occupational therapists have been participating in teams treating people with addictions for decades although their scientific production is quite scarce [ 15 ]. The results are conclusive: The main limitation is the sample size, which is not sufficient enough to absolutely affirm the relationships observed.

assessmejt The battery of neuropsychology tests was based on prior suggestions for cognitive assessment among populations of people being treated for addiction [ 33 ]. The objective of this work is to apply LOTCA to a sample of people receiving treatment for substance addiction and to explore its convergent validity with other occupational and neuropsychological tests used to estimate cognitive deficits.

Results showed interrater reliability coefficients of. No work has been found which uses LOTCA in a population of people with substance addiction undergoing treatment. The sample descriptors can be found in Table 1.

Spearman correlations between the LOTCA scale scores and scale scores obtained with the neuropsychology battery of tests. Williams Riska and C.

However, there is one significant difficulty in designing individual occupational treatments: The battery provides an initial profile of the cognitive abilities of the brain-injured patient that can be used as a starting point for occupational therapy intervention and as a screening test for further assessment.

The scores were placed on a Likert-type scale ranging from 1 to 4 with the exception of items 1—5 regarding categorization, unstructured Risk Object Classification [ 31 ], and structured ROC. Correspondence should be addressed to Gloria Rojo-Mota ; se.
