Peer reviewed Peer reviewed
Direct linkDirect link
Miciak, Jeremy; Taylor, W. Pat; Denton, Carolyn A.; Fletcher, Jack M. – School Psychology Quarterly, 2015
Few empirical investigations have evaluated learning disabilities (LD) identification methods based on a pattern of cognitive strengths and weaknesses (PSW). This study investigated the reliability of LD classification decisions of the concordance/discordance method (C/DM) across different psychoeducational assessment batteries. C/DM criteria were…

Miciak, Jeremy; Fletcher, Jack M.; Stuebing, Karla K.; Vaughn, Sharon; Tolar, Tammy D. – School Psychology Quarterly, 2014
Few empirical investigations have evaluated learning disabilities (LD) identification methods based on a pattern of cognitive strengths and weaknesses (PSW). This study investigated the reliability and validity of two proposed PSW methods: the concordance/discordance method (C/DM) and cross battery assessment (XBA) method. Cognitive assessment…

Subgroups in Language Trajectories from 4 to 11 Years: The Nature and Predictors of Stable, Improving and Decreasing Language Trajectory Groups
Peer reviewed Peer reviewed

McKean, Cristina; Wraith, Darren; Eadie, Patricia; Cook, Fallon; Mensah, Fiona; Reilly, Sheena – Journal of Child Psychology and Psychiatry, 2017
Background: Little is known about the nature, range and prevalence of different subgroups in language trajectories extant in a population from 4 to 11 years. This hinders strategic targeting and design of interventions, particularly targeting those whose difficulties will likely persist. Methods: Children's language abilities from 4 to 11 years…

Classification and Identification of Reading and Math Disabilities: The Special Case of Comorbidity
Peer reviewed Peer reviewed
Direct linkDirect link
Branum-Martin, Lee; Fletcher, Jack M.; Stuebing, Karla K. – Journal of Learning Disabilities, 2013
Much of learning disabilities research relies on categorical classification frameworks that use psychometric tests and cut points to identify children with reading or math difficulties. However, there is increasing evidence that the attributes of reading and math learning disabilities are dimensional, representing correlated continua of severity.…
