Abstract
PURPOSE
Children with neurodevelopmental disorders historically exhibit lower and more variable nonverbal intelligence (NVIQ) scores compared to their typically developing peers. We hypothesize that the intrinsic characteristics of the tests themselves, particularly the cognitive constructs they assess, may account for both the lower scores and variability across tests and over time. Using a qualitative content analysis approach, we examined the extent to which key cognitive constructs are engaged in NVIQ tests and how these constructs compare across different tests.
METHOD
Current editions of seven NVIQ tests were selected based on their relevance in clinical and research settings. Qualitative coding of constructs was developed iteratively by speech-language pathologists and researchers. The codes focused on cognitive domains most affected in highly prevalent neurodevelopmental conditions, including attention, receptive language, statistical learning, and working memory.
RESULTS
We identified multiple subfeatures for our constructs of interest. Using this coding framework, we found that NVIQ tests qualitatively differ in the extent to which these four constructs influence test performance.
CONCLUSIONS
Our findings suggest that understanding the impact of cognitive constructs on NVIQ tests can help explain why children with neurodevelopmental disorders exhibit lower and more unstable NVIQ scores compared to their peers. We provide recommendations for the use of NVIQ tests with neurodevelopmental disorder populations and encourage researchers and clinicians in speech and hearing sciences and psychology to use our results to inform test interpretation and selection.

期刊介绍:
Mission: LSHSS publishes peer-reviewed research and other scholarly articles pertaining to the practice of audiology and speech-language pathology in the schools, focusing on children and adolescents. The journal is an international outlet for clinical research and is designed to promote development and analysis of approaches concerning the delivery of services to the school-aged population. LSHSS seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work.
Scope: The broad field of audiology and speech-language pathology as practiced in schools, including aural rehabilitation; augmentative and alternative communication; childhood apraxia of speech; classroom acoustics; cognitive impairment; craniofacial disorders; fluency disorders; hearing-assistive technology; language disorders; literacy disorders including reading, writing, and spelling; motor speech disorders; speech sound disorders; swallowing, dysphagia, and feeding disorders; voice disorders.
