    Drawing conclusions from the literature regarding the moral development of people with intellectual disabilities (IDs) is difficult because of the use of unstandardised and idiosyncratic measures. In order to address this short-coming, a moral reasoning production measure (the Socio-Moral Reflection Measure – Short Form; SRM-SF) and a recognition measure (the Moral Theme Inventory; MTI) were presented to men with and without IDs who had no known history of engaging in illegal behaviour. The instruments were completed on two occasions, separated by a two-week interval, in order to investigate their basic psychometric properties. The results indicated that there was a strong...

    The current definition of Cerebral Visual Impairment (CVI) includes all visual dysfunctions caused by damage to, or malfunctioning of, the retrochiasmatic visual pathways in the absence of damage to the anterior visual pathways or any major ocular disease. CVI is diagnosed by exclusion and the existence of many different causes and symptoms make it an overall non-categorized group. To date, no discrimination is made within CVI based on types of perceptive visual dysfunctions. The aim of this review was to outline which perceptive visual dysfunctions are to be expected based on a number of etiologies of brain damage and brain...

    We evaluated the efficacy of a vocational training program including behavioral skills training, and a “performance cue system” (i.e., a proprietary iPhone application adapted for the study) to teach targeted social-vocational skills to six young adults with an Autism Spectrum Disorder. In two separate studies, participants were employed to assist in the delivery of a fire safety education program. Participants were asked to wear an inflatable firefighter WalkAround® mascot costume and to perform 63 scripted behaviors in coordination with a fire prevention specialist who was the lead program presenter. In Study 1, three participants were initially exposed to established company...

    Low bone mineral density (BMD) and fractures are common in people with intellectual disabilities (ID). Reduced mobility in case of motor impairment and the use of anti-epileptic drugs contribute to the development of low BMD. Quantitative ultrasound (QUS) measurement of the heel bone is a non-invasive and radiation-free method for measuring bone status that can be used outside the hospital. QUS might be used for screening purposes to identify people with intellectual disability with poor bone status, who are in need of supplementary examination and treatment.To investigate feasibility of QUS in this group, QUS of the heel bone was performed...

    The aim of the present study was to investigate executive functions in adults with intellectual disability, and compare them to a closely matched control group longitudinally for 5 years. In the Betula database, a group of adults with intellectual disability (ID, n=46) was defined from measures of verbal and non-verbal IQ. A control group, with two people for every person with intellectual disability (n=92), was chosen by matching on the following criterion in order of priority: IQ higher than 85, age, sex, sample, level of education, and years of education. Three types of tasks of executive functions were included on...

    This study evaluated whether four persons (two groups) with multiple disabilities and minimal motor behavior would be able to improve their collaborative pointing performance using finger poke ability with a mouse wheel through a Multiple Cursor Dynamic Pointing Assistive Program (MCDPAP) with a newly developed mouse driver (i.e., a new mouse driver that replaces the standard mouse driver, changes a mouse wheel into a thumb/finger poke detector, and intercepts/simulates mouse action). The study was performed according to an ABAB design, in which A represented the baseline and B represented intervention phases. Data showed that both groups of participants improved their...

    The aim of this study was to examine the validation of the Hooper Visual Organization Test (HVOT) for use in children by testing for item fit, unidimensionality, item hierarchy, reliability, and screening capacity. A modified scoring system was devised for the HVOT so that children received some credit for being able to describe the function of objects. The HVOT was administered to 630 typically developing school-aged children and 210 children with Down syndrome matched for age and education. Rasch analysis and receiver operating characteristic curve were applied.Rasch analysis of data from typically developing children showed that twelve items were candidates...

    The main goals of this study were to determine the prevalence, frequency and severity of challenging behaviour in people with profound intellectual and multiple disabilities (PIMD). Because in the literature several health problems and sensory impairments are associated with the onset and existence of challenging behaviour, this relationship was also examined.This study involved 181 people with PIMD (age: mean: 35; SD: 19, 56% male). The Behaviour Problem Inventory was used to determine prevalence, frequency and severity of self-injurious (SIB), stereotypical and aggressive/destructive behaviour, and an additional questionnaire was used to determine the presence of sensory impairments and health problems among...

    The present study analyzed national data from “Domestic Violence Report System” derived primarily from the Council of Domestic Violence and Sexual Assaults Prevention, Ministry of the Interior, Taiwan, to describe the reported prevalence of domestic violence in people with disabilities and to examine the time-effect on the prevalence from years 2006 to 2009. The annual reported prevalence of domestic violence victims in people with disabilities was slightly lower than the general population. However, the reported rate changed significantly in people with disabilities over the period of 2006–2009, the victim number and rate (per ten-thousand) of reported cases in different years...

    ADHD is a neural developmental disorder expressed in various life settings. Yet, previous studies have focused mainly on children's function in school and academic achievement. The purpose of the present study was, therefore, to examine participation patterns in outside formal school activities among boys with ADHD compared to typical boys. Participants included 25 boys aged 8–11 years with ADHD and 25 age-matched typical boys. All participants completed the Children's Assessment of Participation and Enjoyment (CAPE). Several aspects of participation were examined: diversity, intensity, enjoyment, place, and partners in 49 extra curricular activities. The findings indicate that boys with ADHD reported...

    The aim of this paper was to describe the development of the cognitive domain of the Preschool Developmental Assessment Scale (PDAS) for assessment of preschool children with developmental disabilities. The initial version of the cognitive domain consisted of 87 items. They were administered to 324 preschool children, including 240 children from preschools and 84 children with developmental disabilities. Initial Rasch analysis results indicated that the fit statistics of 42 of the items were outside the acceptable range. Based on the fit statistics and considering the overall structure of the scale, the revised version consisted of 40 items and this version...

    Oxygen consumption at peak physical exertion (VO2 maximum) is the most widely used indicator of cardiorespiratory fitness. The purpose of this study was to compare two protocols for its estimation, cycle ergometer testing and the 20m shuttle run, among children with and without probable developmental coordination disorder (pDCD).The shuttle run test was conducted during regular school hours, usually in the gymnasium. Children were then invited to a lab to complete the cycle ergometer protocol. Children were categorized as possible cases of DCD using the Movement-ABC-2. The analysis was performed using cut-points at both the 5th (n=38) and 15th (n=51) percentiles....

    These two studies extended previous research on the use of verbal instructions and support technology for helping persons with mild or moderate Alzheimer's disease perform daily activities. Study I included seven participants who were to carry out one of two previously targeted activities (i.e., either coffee preparation or table setting). Study II included four participants who were to carry out two new activities (i.e., preparation of a fruit salad and of a vegetable salad). The effects of activity engagement on mood (i.e., indices of happiness) were assessed by recording the participants’ behavior during the activity trials and parallel non-activity periods....

    Clozapine has been approved in the United States since 1990 for refractory or treatment resistant schizophrenia in the general population. However, as with many other antipsychotic medications, it is being prescribed for reasons other than those indicated. Among individuals with intellectual disabilities, clozapine is increasingly being prescribed to treat behavioral problems, although the empirical evidence for such a practice is lacking. This review was undertaken as an attempt to summarize the available studies regarding the use of clozapine for behavioral purposes among individuals with intellectual disabilities. Findings of our review suggest that the effectiveness of clozapine in targeting challenging behaviors...

    Assessing social skills is one of the most complex and challenging areas to study because behavioral repertoires vary depending on an individual's culture and context. However, researchers have conclusively demonstrated that individuals with intellectual disabilities (ID) have impaired social skills as well as those with co-morbid autism spectrum disorders (ASD) and epilepsy. However, it is unknown how these groups differ. Assessment of social skills was made with the Matson Evaluation of Social Skills for Individuals with Severe Retardation. One hundred participants with ID were matched and compared across four equal groups comprising 25 participants with ID, 25 participants with epilepsy,...

    We investigated whether motor planning problems in people with Hemiparetic Cerebral Palsy (HCP) are paralleled by impaired ability to use Motor Imagery (MI). While some studies have shown that individuals with HCP can solve a mental rotation task, it was not clear if they used MI or Visual Imagery (VI). In the present study, motor planning and MI were examined in individuals with right HCP (n=10) and controls. Motor planning was measured using an object manipulation task, where participants had to anticipate the end of the motor action. MI was measured using a mental rotation paradigm, where participants judged laterality...


  • Grammatical gender vs. natural gender in French Williams syndrome

    This article reports grammatical gender attribution scores in French Williams participants (N=28, mean chronological age=15.1) in an experiment similar to the classic one from Karmiloff-Smith (1979) where grammatical gender was pitted against natural gender. WS participants massively opted for the masculine gender as the default one, just as MA-controls did. They differed from CA-controls, however, in that they provided fewer sex-based responses. Splitting the WS group into two subgroups did not reveal a shift to sex-based responses similar to the one found in controls. It is argued that this latter difference could plausibly be related to differences in cognitive, lexical...

    Using the Japanese version of school form of the ADHD-RS, this survey attempted to compare the scores between the US and Japan and examined the correlates of ADHD-RS. The classroom teachers of 7414 children (3842 males and 3572 females) evaluated all the children's behaviors. A confirmed factor analysis of ADHD-RS confirmed the two-factor solution (Inattentive and Hyperactive-Impulsive) same as previous studies. ADHD-RS scores were not related to IQ, but were associated with standardized achievement test scores. Males showed stronger ADHD tendencies than did the females, and the males tended to score lower as they grew older. Our comparison of the...

    The purpose of this manuscript was to develop and test the psychometric properties of the Environmental Restriction Questionnaire (ERQ) a parent-reported questionnaire for measuring perceived environmental restrictions for young children participation. Reliability and homogeneity were tested by Cronbach's alpha and inter-item correlations. Construct validity was computed by factor analysis and known group differences analysis. Convergent and divergent validities were calculated by correlation with the Children Participation Questionnaire (CPQ). Participants were 290 children and their parent. Seventy-five children who were referred to occupational therapy evaluation as consequence of moderate developmental disabilities and 215 children without any disability (mean age±standard deviation for...
