Introduction: Intellectual disability is a key subject in all mental healthcare institutions, including the forensic mental health services. The Screener for Intelligence and Learning Disability (SCIL) is designed to screen for intellectual disability in forensic populations. So far, this assessment method is only validated in "detention fit…

Background: The Learning Disability Screening Questionnaire (LDSQ) has been shown to have high sensitivity and specificity to identify those who are likely to meet intellectual disability diagnostic criteria (McKenzie, et al. [McKenzie K., 2015]). However, there is no independent research to date to support these findings. Materials and Methods:…

The Learning Disability Screening Questionnaire (LDSQ), a brief screening tool for intellectual disability, was originally validated against the Weschler Adult Intelligence Scale, Third Edition (WAIS-III), which was superseded by the Weschler Adult Intelligence Scale, Fourth Edition (WAIS-IV) in the United Kingdom in 2010. This study examines the…

This study examined the validity of using teacher-administered educational and intelligence tests to screen students for learning disabilities (LDs). Twenty-seven Technical and Further Education (TAFE) students from regional Victoria who were enrolled in a program that was designed to reconnect school dropouts with education via TAFE participated…

Youth with autism spectrum disorder (ASD) often present with emotional problems such as anxiety and depression (American Psychiatric Association, 2013). A recent study of the "Child Behavior Checklist 6-18" (CBCL; Achenbach & Rescorla, 2001) indicated good sensitivity but relatively low specificity for identifying emotional problems…

Demonstrated that equally weighting Wechsler Adult Intelligence Scale subtests that differ in validity reduces potential validity. Concluded that vocabulary and information in concert have greater validity than either subtest by itself and that the addition of a third test will not result in a consistent increase in validity.

Utilized time-saving Wechsler Adult Intelligence Scale (WAIS) scoring procedures in two ex post facto investigations following approaches outlined by Vincent (1979) and Himelstein (1983). Results indicated high correlation between the Vincent and Himelstein approaches and WAIS Verbal, Performance, and Full Scale IQs while maintaining integrity of…

Investigated the Vocabulary-Block Design short form for the Wechsler Intelligence Scale for Children (Revised), Wechsler Adult Intelligence Scale and Wechsler Adult Intelligence Scale (Revised) in a sample of 126 male delinquent adolescents. Concluded that short forms, especially the WAIS and WAIS-R, are useful screening tests. (Author/JAC)

Investigated validity of two- and four-subtest combinations as estimates of Wechsler Adult Intelligence Scale-Revised (WAIS-R) Full Scale IQ among clients of low IQ (N=100). Concluded that the four-subtest form was superior as a screening device when complete administration of the WAIS-R is not feasible. (NRB)

Investigated the utility of the Revised Beta as a screening device for low-functioning minority-group criminal offenders. Mean scores for this sample were correlated only mildly. This finding contradicts prior research and creates the need for caution in using the Beta as a screening device with this population. (Author)
