“…The assessment results in an index that had been found to correlate significantly with those on the Kaufman Brief Intelligence Test and on the Vineland Adaptive Behavior Scales (Hayes, 2002). The HASI also correlated significantly with the WASI (Sondenaa et al, 2008(Sondenaa et al, , 2011 and the WAIS-III (Ford et al, 2008;Sondenaa et al, 2007). Using the original HASI cut-off score of 85 (Hayes, 2002), previous research using a Receiver Operating Characteristic (ROC) curve analysis have reported a sensitivity of 100% using the WAIS-III (Sondenaa et al, 2007) or WASI (Sondenaa et al, 2011) as a criterion validity and a specificity of 35.4% when using the WASI (Sondenaa et al, 2011), and 57% when using the WAIS-III (Sondenaa et al, 2007) …”

“…The study of Hayes (2002) Characteristic (ROC) curve analysis with a HASI cut off score of 85 showed a sensitivity of 82.4% for the KBIT, 71.2% for VABS and specificity of 71.6% for the KBIT and 71.2% for the VABS. However, in an adolescent offender sample in the United Kingdom the HASI was reported not having adequate specificity to be helpful in identifying possible ID (Ford et al, 2008). Ford and his colleagues (2008) observed significant relationships between the HASI and the Wechsler Adult Intelligence Scale -III (WAIS-III; r = 0.553; p < 0.01) and the VABS (r = 0.377; p < 0.01).…”

There is an increasing interest in screening instruments to detect Intellectual Disability (ID) in a quick and accurate way in mental health services as well as in the criminal justice system in order to provide appropriate support for people with undetected needs caused by ID. An instrument that has been proven to be useful in both settings is the Hayes Ability Screening Index (HASI). This study assessed the validity of the Dutch version of the HASI in persons with a substance abuse problem residing in mental health services, whether or not mandated to treatment by court order. The HASI was conducted along with the Wechsler Adult Intelligence Scale III as the criterion for validity to 90 participants. Additionally, the influence of psychiatric disorder and medication use on the HASI result was examined. A significant positive relationship was found between the two instruments, demonstrating convergent validity. Using a Receiver Operating Characteristic (ROC) curve analysis, the discriminative ability of the HASI with a cut-off score of 85 was found to be adequate, yielding in a good balance between sensitivity and specificity. The HASI was not distorted by the presence of the substance abuse problem or other psychiatric illnesses and medication did not influence the HASI scores in this study. These findings indicate that the HASI provides a time-efficient and resource-conscious way to detect ID in persons with a substance problem, thus addressing a critical need in mental health settings.

“…For example, there has been an increasing interest in identifying children and adolescents who come in contact with forensic services (Ford, Andrews, Booth, Dibdin, Hardingham, & Kelly, 2008). Recent research with the adult version of the intellectual screening tool (McKenzie, Michie, Murray & Hales, 2012), from which the CAIDS-Q was partly developed, demonstrated both convergent and discriminative validity of the LDSQ in forensic settings, but suggested that a higher cut-off score may increase the sensitivity of the tool when used in such services.…”

“…In a clinical context the ability to use the scale total scores to estimate functional ability is likely to be particularly useful in situations where there may be a lengthy wait for formal diagnosis, but an early indicator of the potential support needs of a child is needed to allow planning for support to begin. It may be equally useful in forensic settings, where a quick and easy indicator of the functional abilities of a young person may allow potentially vulnerable young offenders to be identified and supported at an early stage (Ford et al, 2008). Similarly, researchers may find it useful to have an indication of functional ability in order to be able to match intellectually impaired individuals with controls, without the need for full diagnostic assessments that can be timeconsuming (Winters, Collett, & Myers, 2005) and expensive to administer.…”

Screening tools can provide an indication of whether a child may have an intellectual disability (ID). Item response theory (IRT) analyses can be used to assess whether the statistical properties of the tools are such that their utility extends beyond their use as a screen for ID. We used non-parametric IRT scaling analyses to investigate whether the Child and Adolescent Intellectual Disability Screening Questionnaire (CAIDS-Q) possessed the statistical properties that would suggest its use could be extended to estimate levels of functional ability and to estimate which, (if any), features associated with intellectual impairment are consistently indicative of lower or higher levels of functional ability. The validity of the two proposed applications was assessed by evaluating whether the CAIDS-Q conformed to the properties of the Monotone Homogeneity Model (MHM), characterised by uni-dimensionality, local independence and latent monotonicity and the Double Monotone Model (DMM), characterised by the assumptions of the MHM and, in addition, of nonintersecting item response functions. We analysed these models using CAIDS-Q data from 319 people referred to child clinical services. Of these, 148 had a diagnosis of ID. The CAIDS-Q was found to conform to the properties of the MHM but not the DMM. In practice, this means that the CAIDS-Q total scores can be used to quickly estimate the level of a person's functional ability. However, items of the CAIDS-Q did not show invariant item ordering, precluding the use of individual items in isolation as accurate indices of a person's level of functional ability.
