Dynamic Lowenstein Occupational Therapy Cognitive Assessment: Evaluation of Potential to Change in Cognitive Performance

Abstract

OBJECTIVE. We studied the psychometric properties of the dynamic version of the Lowenstein Occupational Therapy Cognitive Assessment (DLOTCA) and examined the most frequent level of mediation used for planning for intervention.METHOD. Participants included 83 clients hospitalized after first stroke (mean age 5 57.7, standard deviation 5 8.33) and 45 healthy control participants. All were assessed with the DLOTCA after providing informed consent. RESULTS.Interrater reliability showed high correlations between all pairs of raters. Internal consistency reliability showed moderate to high as (.602-.813) for all domains except Visual Perception. We found significant differences between the groups of participants before mediation; both benefited from mediation, showing moderate to high effect sizes. Stroke clients needed higher levels of mediation.CONCLUSION. The DLOTCA is effective in providing insight into whether participants need mediation and the level and type of assistance they require. The DLOTCA provides guidance for planning intervention for people with cognitive disabilities.

Cross cultural adaptation of the adolescent/adult sensory profile: establishing linguistic equivalency and psychometric properties of the Arabic version

“…The combination of personal factor evaluations, such as the Sensory Profile, with functional evaluations provides occupational and rehabilitation therapy practitioners with essential data for planning effective interventions and helping people achieve their desired goals [23]. The translation of the Adolescent/Adult Sensory Profile yielded an Arabic version of the Adolescent/Adult Sensory profile with very good psychometric properties.…”

Convergent validity of the Occupational Therapy Adult Perceptual Screening Test (OT-APST) with two other cognitive-perceptual tools in a South African context

“…The 'after mediation' score is obtained after the therapist has given the patient cues on the failed item. The mediation cues are based on Toglia's guidelines 26 . The amount of mediation will determine the length of administration, it may take one to two hours and it may be done in two sessions 25 .…”

“…The results in the DLOTCA are not compared with a normative sample and results from a dynamic tool are considered to be more ecologically valuable as compared to static tools 26 . The DLOTCA which was used in this research, has 28 items grouped under seven subscales which include the Orientation, Awareness, Visual Perception, Spatial Perception, Praxis, Visuomotor Construction and the Thinking Operations.…”

Reliability and internal consistency of the Danish version of Loewenstein Occupational Therapy Cognitive Assessment 2nd Edition (LOTCA-II/D)

“…In the acute rehabilitation setting, however, requests have been made for an instrument that does not require certification and is able to assess the patient's cognitive dysfunctions in order to supplement or substitute these occupational performance tests. The original Loewenstein Occupational Therapy Cognitive Assessment, second edition (LOTCA-II), is a standardized and valid outcome measure, which evaluates a broad range of basic cognitive functions, and which requires no certification (8)(9)(10)(11)(12)(13). LOTCA-II was published in 2000 after a revision of the first edition from 1990 (9).…”
