Within the Canadian context, the two major learning disability classification systems are arguably the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders and the Learning Disabilities Association (LDAC) of Canada's Official Definition of Learning Disabilities. Several of the more recent changes to the fifth edition of the DSM contrast with the LDAC definition, which establishes them as competing diagnostic frameworks. We investigated the frequency of math learning disability identification when both the LDAC and DSM-5 criteria were modelled and applied to an archived data set (2011–2016). Results support generally similar percentages of math learning disability cases identified when employing LDAC or DSM-5 criteria; however, the two methods identified a different set of cases. Implications for using DSM-5 versus LDAC criteria in diagnosing learning disabilities are discussed, including the need to consider adopting a national diagnostic standard. [ABSTRACT FROM AUTHOR]

Background: Children with a specific learning disability (SLD) have deficits in everyday occupations along with executive function in addition to academic issues., Objective: The present study is aimed at investigating the effectiveness of Occupational Performance Coaching (OPC) and the Four - Quadrant Model of Facilitated Learning (4QM) interventions on the participation in occupational performance and executive function skills in children with SLD., Method: This study was a single-case experimental design (multiple baselines) in which six children with SLD were randomly assigned to three groups. In the baseline phase, three groups of children underwent repeated executive function assessments using the Stroop Color and Word Test (SCWT) and the Wisconsin Card Sorting Test (WCST) in the multiple baselines. In the intervention phase, all six mothers of children with SLD individually received OPC and 4QM interventions once a week for 14 sessions of 60 minutes and during this period, children were evaluated six more times for executive function skills according to SCWT and WCST. In addition, The Canadian Occupational Performance Measure (COPM) and Behavior Rating Inventory of Executive Function (BRIEF) at the beginning and the end of the baseline phase and the end of the intervention phase were completed by mothers of children with SLD., Results: More than 50% PND of the SCWT and WCST in the visual analysis graph's information along with significant changes in COPM scores and large effect size of BRIEF subscales (Cohen's d ≥ 0.8) in pre- and postintervention showed the effectiveness of OPC and 4QM on the participation in occupational performance and executive function skills in children with SLD., Conclusion: The results of the study support the effectiveness of OPC and 4QM interventions on children with SLD. However, research with more participants and experimental methods can provide further evidence., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Amin Ghaffari et al.)
