The Effects of Play and Competition-Based Cognitive Therapy

Executive Dysfunction Clinical Trial

Official title: The Effects of Play and Competition-Based Cognitive Therapy on Executive Functions and Occupational Routines in Children With Dyslexia

Status Completed

Clinical Trial Summary

Purpose: The aim of this study was to investigate the effects of play and competition-based cognitive therapy (PCB-CT) on executive function and occupational routines in children with dyslexia.

Method: In this randomized control trail, 64 children with dyslexia (between 7-12 ages) were randomly selected from the 162 clients who applied to the clinic. Children were divided randomly into a treatment group and a control group. Children in the intervention group was given cognitive therapy for 10 weeks, 3 days a week for one hour sessions while no therapy was received to the control group. In order to evaluate the cognition of the children Test of Visual Perceptual Skills-3 (TVPS-3) and Dynamic Occupational Therapy Cognitive Assessment (DOTCA-Ch), to evaluate executive functions the Behavior Rating Inventory of Executive Function (BRIEF) and to evaluate occupational routine The Executive Functions and Occupational Routines Scale (EFORTS) were used. The evaluations were done at baseline, after treatment and the end of the 3rd month for both groups.

Clinical Trial Description

The participants included in this study if they had only dyslexia diagnosis, aged between 7-12 years and had a 90 and above IQ score (normal IQ), in addition didn't have multiple conditions (neurological problems such as epilepsy) or primary psychiatric comorbidities (i.e. depression, anxiety, psychosis).

Test of Visual Perceptual Scale-3(TVPS-3); The TVPS-3 was originally designed for children but the author Dr. Gardner also reported statistically significant differences between three groups diagnosed as having either developmental delay, head injury or learning disability. This test in its third edition has been revised by Martin for appropriate use in an adult population, with scores compared against the highest age group of scores (i.e. 18y 00-18y 11m) (Martin, 2006). There are seven subtests of eighteen stimuli figures each, which assess seven key areas of visual perception. Each subscale consisting of eighteen figures including two example items and sixteen test items are arranged in order of increasing complexity (see App. A). The test is largely an untimed instrument with the exception of subtests for visual memory and visual sequential memory being allocated a five second presentation time per item. Response time is however not restricted for any of the items.

The Dynamic Occupational Therapy Cognitive Assessment instrument designed to assess the cognitive abilities and learning potential of children from ages 6 to 12 years via a dynamic mediation testing process. DOTCA-Ch, a criterion-referenced assessment, was designed to fill this need. Originally based on the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA), an assessment for adults with neuropsychological deficits, the DOTCA-Ch represents an adapted and modified format that is appropriate for use with school-age children. The DOTCA-Ch battery consists of 22 subtests in 5 cognitive domains: Orientation, Spatial Perception, Praxis, Visuomotor Construction, and Thinking Operations. Construct validity was supported by comparing children with traumatic brain injury and learning disabilities to typically developing children, and ecological validity of children with attention deficit hyperactivity disorder by comparing performance on the DOTCA-Ch to the School Function Assessment. Results of the intraclass correlation coefficients analysis revealed very high reliability coefficients for all cognitive domains, ranging from .87 to .99.

The Behavior Rating Inventory of Executive Function (BRIEF) assesses problem behaviors associated with executive function. The form consists of 86 brief descriptions of behavior problems, the frequency of which teachers and parents are asked to rate as occurring either never, sometimes, or often. Responses are aggregated to form eight subscales (Inhibit, shift, emotional control, initiate, working memory, plan/organize, organization of materials and monitor scale). Examples of test items from each subscale are shown in the Appendix C and D. T-scores are calculated for each measure. The scales showed high internal consistency on the BRIEF (a=.80-.90) for both Teachers and Parents form. The moderate test-retest reliabilities for teachers BRIEF (.90-.92) and for the parent BRIEF (.80-.83). Interrater reliability of the teachers BRIEF is reported as .17-.28, and of the parents BRIEF as .32-.34. Both tools are reported to have evidenced for content of the items, convergence and divergence of their scores with other measures. ;
