The Development of a Screen to Identify Individuals Who May Need Support with Their Learning Analytical Summary 2018 The development of a screen to identify individuals who may need support with their learning Helen C Wakeling The identification of individuals serving prison and community sentences who may have a mild learning disability (LD) or may find learning and day to day activities challenging, and therefore require particular help and support in their everyday living, is critical to ensure they are able to get the most out of their sentence. Her Majesty’s Prison and Probation Service (HMPPS) are committed to supporting people with challenges to learning as much as for those without. On a population level, identifying the number of people in prison and serving community sentences who may struggle and need support would be helpful to improve the targeting of resources and to ensure the commissioning of appropriate services. On an individual level, referring those who may be more likely to have learning disabilities and difficulties coping with prison life for further assessment of their difficulties, or flagging them for additional support, has the potential to be helpful to those individuals and to the staff responsible for their care. This study reports on the development of a screen using the Offender Assessment System (OASys; Home Office, 2006). For the purpose of this research, we are aiming to identify individuals who may struggle with prison or community sentences because of learning disabilities or learning challenges, and thus may need additional support. Some of these will likely have a mild LD (as defined by the World Health Organisation) with an intelligence quotient (IQ) of less than 70, whereas others will have an IQ of between 70 and 80, and therefore would not meet the diagnostic criteria for a mild LD, but who nonetheless may still have challenges with learning and managing day to day. Key findings • A sample of 2,232 adult males who had been convicted of a sexual offence and who were serving a custodial sentence was used. All had IQ information available using the Wechsler Adult Intelligence Scale (WAIS IV). In the present study we suggest that WAIS IQ data can be used as a marker for the identification of those who may require support with learning and everyday living while serving their sentence. • Twenty-nine OASys items, which were found to be associated with IQ, were entered into a logistic regression with IQ (higher >=80 / lower <=79) as the outcome variable. Eight variables significantly predicted lower IQ (<= 79): no fixed abode, (lack of) work skills, problems with reading, writing and numeracy, reading problems, numeracy problems, learning difficulties, (no) qualifications, and easily influenced. • A stepwise logistic regression was performed entering in these 8 variables. The final model contained 7 of the 8 variables (easily influenced did not add to the model): (no) qualifications, learning difficulties, problems with reading, writing and numeracy, reading problems, numeracy problems, no fixed abode, and (lack of) work skills. • A seven-item tool was developed, which had good predictive validity. • Possible uses of the tool are discussed. These include using the tool as a means of approximating the proportion of those in our care who may require support with learning and everyday living while serving their sentences. The tool could also be used as a way of helping to refer individuals for further assessment of their needs. The views expressed in this Analytical Summary are those of the author, not necessarily those of the Ministry of Justice (nor do they reflect government policy). Context The aim of the current research was to develop a screening tool to: 1) help identify the approximate extent The World Health Organisation (WHO, 1992) defines an of individuals with an IQ of less than 80, including those intellectual or learning disability (LD) as a significant who may have an LD, who may struggle to cope in the reduced ability to understand new or complex information prison population; and 2) facilitate the identification of and to learn and apply new skills, which results in a individuals within prison or serving community reduced ability to cope independently (impaired social sentences, who require further assessment of their functioning), and begins before adulthood. IQ levels are difficulties, as well as further support. used as a guide and the range of 50-69 is usually indicative of mild learning disability (although IQ levels Method alone are not sufficient to diagnose LD). The DSM-V (American Psychiatric Association, 2013) definition of Sample ‘Intellectual Disability’ refers to limited functioning in 3 A sample of 2,232 adult males who had been convicted areas: social skills (e.g. communicating with others), of a sexual offence and who were serving a custodial conceptual skills (e.g. reading and writing ability) and sentence was used. All had taken part in a cognitive practical ability (e.g. clothing/bathing one’s self). LD is behavioural treatment programme, collectively known as distinct to ‘specific learning disabilities’ or ‘learning the Sex Offender Treatment Programmes (SOTPs; Mann difficulties’ which refer to a variety of disorders that affect & Fernandez, 2006) targeted at individuals who had the acquisition, retention, understanding, organisation or committed a sexual crime between 2006 and 2011. This use of verbal and/or non-verbal information, such as sample was used as all had IQ information available from dyslexia and dyscalculia (Davey, 2008). Although there is the Wechsler Adult Intelligence Scale (WAIS IV; discrepancy on the prevalence of individuals with LD Lichtenberger & Kaufman, 2009). At the time, WAIS IV within the Criminal Justice System (CJS) due to the lack was routinely used on all individuals participating in these of established tools, it is estimated that between 20% programmes. The average age of the sample was 38.8 and 30% of the prison population have some form of LD and their average IQ was 94.2. Four hundred and fifty- or difficulties that interfere with their ability to cope with two individuals (20%) had an IQ score of 79 or less, and the CJS (Loucks, 2007). It is estimated that around 7% of 1,780 (80%) had an IQ score of 80 or more. One prisoners have an IQ of less than 70, whereas a further hundred and fifty-nine individuals had an IQ score of 69 25% have an IQ of between 70 and 79 (Mottram, 2007). or less (7.2%) and 2,218 had an IQ score of 70 or more It is also estimated that individuals with LD are (92.8%). overrepresented in the CJS (e.g. Holland, 2004), which includes both those in prison and on probation. Measures However, estimations of the extent of the problem are WAIS IV difficult without established and validated means of The WAIS IV (Lichtenberger & Kaufman, 2009) was measurement. The HM Inspectorate of Prisons completed on all individuals prior to their participation highlighted the failure within the CJS to identify in an SOTP. Assessments were conducted at the individuals with LD (HMIP, 2015). Without a means of establishment at which the individuals started a identifying individuals it is likely that an individual with LD programme. or difficulties coping with the CJS will not be identified IQ classification is primarily used by health professionals and, in turn, that their support needs will not be met to assess the presence of LD and/or difficulties coping. (Talbot, 2009). This may cause problems for the However, the use of IQ as a marker of difficulties is not individual and for the staff who work with them, who are without its issues; impairments of social functioning and not able to appropriately identify the individuals who communication skills should be present in addition to a need further support.

There are 5,053 subjects from 64 schools under the Mahasarakham Primary Education Office. Stratified Random Sampling is applied in selecting the subjects. The subjects are divided according to their districts and school sizes (Small, Medium-Sized, and Large) with three units: schools, classrooms, and students. The results are shown in both “Descriptive Statistics” to describe demographic factors and “Inferential Statistics” to compare the cognitive levels among the elementary school students from different demographic factors. The results of the study indicate that the IQ of the primary school students in Mahasarakham Province is at the normal level. Most of them, 3,358 students or 66.46%, have the average level of IQ. 148 students or 2.93% have the higher-than-average level while 68 students or 1.35% had the lower-than-average level.

  • Measurement of Intelligence in Children and Adolescents with Autism Spectrum Disorder: Factors Affecting Performance
    Measurement of Intelligence in Children and Adolescents with Autism Spectrum Disorder: Factors Affecting Performance A doctoral dissertation submitted to the Graduate School of the University of Cincinnati in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Psychology of the College of Arts and Sciences by Katherine T. Baum, M.A. September 1, 2011 Committee: Paula Shear, Ph.D. (Chair) Somer Bishop, Ph.D. Steven Howe, Ph.D. Sarah Whitton, Ph.D. Abstract The assessment of children with autism spectrum disorders (ASD) requires the measurement of intelligence, because the diagnostic criteria include a judgment about whether social and communication deficits are greater than would be expected given the general developmental level of the child. In addition, results of cognitive testing, including IQ scores and the potential discrepancy between verbal and nonverbal intellectual abilities, impact educational placement, treatment strategies, research design, and theories of neurodevelopment and cognition in ASD. Despite its widespread importance, there are fundamental methodological aspects of intellectual assessment in ASD, such as the intelligence measure selected, that may affect testing results. The Wechsler Intelligence Scale for Children (WISC) and the Stanford-Binet (SB) are two of the most commonly used measures to evaluate intelligence in ASD. Full-scale and composite scores on the WISC and SB have been shown to be highly correlated with each other in several pediatric populations, including children with mild intellectual disability (ID) or attention-deficit hyperactivity disorder (ADHD), as well as in typically-developing children. Despite these high correlations, significant discrepancies between the scores, as many as 20 IQ points, have been reported for an individual.

Since the appearance of the first WAIS scale, there has been a widespread attempt by researchers in the assessment of cognitive abilities to find short forms that facilitate the clinical practice of professionals in those situations where conditions, either because of the time available or the clinical characteristics of patients, do not require the use of an extensive tool. Objective. To carry out a systematic review of the short forms of up to four subtests extracted from the WAIS-III and WAIS- IV scales. Method. Conduct a search for information in the PsycINFO database and make a systematic review of the information following PRISMA guidelines. Results. Of the 47 studies found, 36 were selected for full-text revision, of which 13 were finally included in this review: 6 of the WAIS-III and 7 of the WAIS-IV. Different forms achieved good results in the quality criteria established in a variety of samples. Discussion and conclusion. There are several forms that are useful for estimating IQ, according to the samples and the quality criteria used. Keywords: WAIS-III; WAIS-IV; IQ.

Richard Lynn set the mean IQ of the United Kingdom at 100 with a standard deviation of 15, and he calculated the mean IQs of other countries in relation to this “Greenwich IQ”. But because the UK test scores could be declining, the present paper recalibrates the mean IQ 100 to the average of seven countries having a historical mean IQ of 100. By comparing Lynn-Vanhanen-IQ with PISA scores and educational attainment of native and foreign born populations transformed into the IQ metric, we confirmed brain gain and brain drain in a number of nations during recent decades. Furthermore, the growth of gross domestic product per capita can be derived as a linear function of the percentage of people with an IQ above 105 and its underlying frequency of a hypothetical major gene of intelligence. Key Words: General intelligence; PISA; GDP; Dysgenics; Smart fraction theory. The Calibration of National IQ Means Most intelligence tests, such as those used by Lynn and Vanhanen (2002, 2006) in their compilations, have been constructed in Britain and the United States and have subsequently been administered to samples of the populations in other countries throughout the world.

All participants had at least average intelligence and a diagnosis of autism spectrum disorder. Descriptive statistics and binary logistic regressions were used to examine the prevalence and predictors of a “daily living skills deficit,” defined as below average daily living skills in the context of average intelligence quotient. Approximately half of the adolescents were identified as having a daily living skills deficit. Autism symptomatology, intelligence quotient, maternal education, age, and sex accounted for only 10% of the variance in predicting a daily living skills deficit.
