Substance addiction is a health problem that affects all areas of individual functioning and their relation with environment. Participants and Procedures The sample was obtained from a specific urban, public, and free center that cognitkve people with substance addictions in the city of Madrid: The criterion for inclusion in this study was complying with the requirements for being diagnosed with a Substance-Related Disorder, as per the DSM-5 [ 30 ].

This happens in both cases of substance addictions [ 6 ] and cases of behavioral addictions [ 7 ]. LOTCA is a relatively systematic test that can be useful for initial assessments of people who are beginning treatment for addictive behaviors with or without awsessment.

Loewenstein Occupational Therapy Cognitive Assessment to Evaluate People with Addictions

There were no significant differences between the scores obtained by men and women on the LOTCA scales 0. Spearman correlations between the LOTCA scale scores and scale scores obtained with the neuropsychology battery of tests.

Measurement and Management of Cognitive DisabilitiesC. 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. Previous studies have shown that neuropsychological alterations are associated with reduced level of involvement and participation of drug dependent individuals in treatment programs and with a higher rate of dropping out of these programs [ 12 ], to the extent that individuals with addictive behaviors may have considerable difficulty in becoming aware of their own deficit, to understand and reason complex instructions, to inhibit impulsive responses, to plan their daily activities, and to make everyday decisions [ 13 ].

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.

Review of international databases]. This review found a critical deficit in the availability of occupational assessment instruments, which have been validated in the field of addictions. The people access this service directly and are assessed using diagnostic interviews by a multidisciplinary team doctors, nurses, psychologists, social workers, and occupational therapists. When necessary, this was confirmed with the visible ultraviolet spectrophotometry method to find metabolites of opiates, cocaine, cannabis, and benzodiazepines in the urine or breath alcohol testing one subject was excluded due to active consumption upon assessment.

This work explored the existence of a relationship between both types of tests. The results are conclusive: 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 ]. A confirmatory factor analysis was done on the theoretical structure of the survey using the unweighted least squares method since ordinal categorical items were used and normality was not expected in the distribution of the data.

The occupational tests were administered simultaneously by two occupational therapists principal and observant evaluator and the neuropsychological tests by three neuropsychologists each patient was assigned to one of them. Table of Contents Alerts. There are also significant correlations with attention span tests as concerns both numbers and other types of symbols.

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 ]. It provides an assessment of basic cognitive skills required for everyday function, including orientation, visual perceptual and psychomotor abilities, problem-solving skills, and thinking operations.


However, it must be supplemented with other tests for a full and ecological assessment of patients. Subscribe to Table of Contents Alerts. Because it is not meaningful to add up unrelated areas of cognitive and perceptual skills, we did not calculate a total score for the LOTCA.

The battery takes 30 to 45 minutes to administer. This site uses cookies.

The sample descriptors can be found in Table 1. Study Objectives The objective of this work is to loewenstsin LOTCA to a sample of people receiving treatment for substance addiction threapy to explore its convergent validity with other occupational and neuropsychological tests used to estimate cognitive deficits.

The criteria for exclusion were having previously suffered any type of brain 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.

In order to complete the three tasks successfully, the person must pay attention to llewenstein 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.

The battery of neuropsychology tests was based on prior suggestions for cognitive assessment among populations of people being treated for addiction [ 33 ].
