    ABSTRACT: In this exploratory study, 46 sisters of moderately to profoundly developmentally disabled individuals, 12-69 years of age, completed questionnaires that included measures of their sibling relationships with disabled and non-disabled siblings, their family experiences within the family of origin, and their opinions concerning service delivery and policy issues in the field of developmental disabilities. Subjects were volunteers from among families contacted by social service agencies in Southeastern Michigan. The sibling relationship scores generally depicted positive, but non-intimate, relationships with the disabled siblings; in addition, these relationships were non-reciprocal in terms of domination, admiration, and nurturance. Furthermore, relationships with disabled siblings were lower in intimacy, similarity, admiration, competition, and being nurtured than were relationships with non-disabled siblings in the same families. Nurturance of and domination over a sibling were rated higher with disabled siblings than with non-disabled siblings. Overall family effectiveness and most of the component family factor scores for the subjects' families were higher than scores from a mental health clinic sample, and were generally similar to scores from a normative sample. No definitive trends in the data were linked to age of the subjects; however, there were associations with sibship constellation factors (birth order and age span between subjects and their disabled siblings) and characteristics of the disabled siblings (gender, level of impairment, and age). This review and research have significance for professionals involved with service delivery and program planning for developmentally disabled individuals and their families, as well as for social scientists studying general sibling relationships.

    ABSTRACT: Multiple aspects of memory were examined in 42 boys with fragile X syndrome and a comparison group of 42 typically developing boys matched on MA. Working memory, incidental memory, and deliberate memory were assessed with a battery that included both free-recall and recognition tasks. Findings indicated that boys with fragile X syndrome performed more poorly than their matches on most measures. The exception was free recall, in which their accuracy was equal to that of the control participants. Results from analyses of a subset of boys with fragile X syndrome who exhibit characteristics of autism and their MA matches, though preliminary, support the conclusion that memory deficits are especially marked in boys who have fragile X syndrome and evidence autistic behaviors.

    ABSTRACT: We examined the peer interactions and academic engagement of 23 middle and high school students with developmental disabilities within inclusive academic and elective classrooms. The extent to which students with and without disabilities interacted socially was highly variable and influenced by instructional format, the proximity of general and special educators, and curricular area. Peer interactions occurred more often within small group instructional formats, when students were not receiving direct support from a paraprofessional or special educator, and in elective courses. Academic engagement also varied, with higher levels evidenced during one-to-one or small group instruction and when in proximity of general or special educators. Implications for designing effective support strategies for students with autism and/or intellectual disability within general education classrooms are discussed.

    ABSTRACT: Using a cross-lagged panel design, we investigated the impact of positive family processes on change in autism symptoms and behaviors. A sample of 149 co-residing mothers and their adolescent or adult child with autism was drawn from a large, longitudinal study. Maternal warmth and praise were measured using coded speech samples in which mothers talked about their son or daughter. A high level of relationship quality was associated with subsequent reductions in internalizing and externalizing problems as well as reductions in impairments in social reciprocity and repetitive behaviors. Maternal warmth and praise were also related to symptom abatement in the repetitive behaviors domain.

    ABSTRACT: Adults with Down syndrome and early stage Alzheimer's disease showed decline in their ability to selectively attend to stimuli in a multitrial cancellation task. They also showed variability in their performance over the test trials, whereas healthy participants showed stability. These changes in performance were observed approximately 2 years prior to a physician's diagnosis of possible Alzheimer's disease, which was made when they were exhibiting declines in episodic memory suggestive of mild cognitive impairment. Performance on this task varied with the evolution of dementia, showed modestly good sensitivity and specificity, and was relatively easy to administer. Given these qualities this task could be a valuable addition to a neuropsychological battery intended for the assessment of mild cognitive impairment and Alzheimer's disease in adults with Down syndrome.

    ABSTRACT: The analysis of the early development of self-injurious behavior (SIB) has, to date, reflected the wider distinction between nature and nurture. Despite the status of genetic factors as risk markers for the later development of SIB, a model that accounts for their influence on early behavior-environment relations is lacking. In the current paper we argue that the investigation of gene-environment interactions (GxE) and other forms of gene-environment interplay could potentially enhance current approaches to the study of self-injury. A conceptual model of the early development of SIB based explicitly on such relations is presented. The model is consistent with the basic tenets of functional analysis. Implications for research and the assessment, treatment, and prevention of SIB are discussed.

    ABSTRACT: There has been limited research on the role of sociocognitive factors in depression with people who have a mild intellectual disability. However, an association has been found between negative social comparison and depressed mood. We extend previous work by including individuals with clinical depression. A between-groups design of 18 depressed versus 18 nondepressed participants was used. Depression measures were administered, along with measures of self-esteem and social comparison. Participants reported the salience of the social comparisons they made. Depressed participants reported significantly more negative social comparisons; the nondepressed group reported that the positive comparisons they made were more salient. These results have implications for cognitive behavior interventions and the possibility of working with people in the context of their interpersonal beliefs.

    ABSTRACT: Our purpose in this cross-sectional study with 1,598 adult clients who had intellectual disabilities was to obtain valid prevalences of sensory impairments and to identify associations. The diagnoses were made through ophthalmologic and audiometric assessments, applying WHO/IASSID definitions. Re-weighted prevalences were 5.0% (95% CI 3.9- 6.2%) for the total adult population; 2.9% (1.9-4.1), less than 50 years; and 11.0% (7.9- 14.7), 50 years and over. Apart from being 50 years of age and over, p = .000, risk factors were more severe intellectual disability, p = .0001, and Down syndrome, p = .001. Results show that the risk of combined sensory impairment in this population is considerably increased compared with the general population. Part of the underlying conditions are treatable or can be rehabilitated. However, the complete diagnosis had been identified in only 12%.

    ABSTRACT: Changes in health, functional abilities, and behavior problems among 150 adults with Down syndrome and 240 adults with mental retardation due to other causes were examined with seven assessments over a 9-year period. Adults were primarily younger than 40, the age at which declines begin to be evident in individuals with Down syndrome. Adults with Down syndrome were advantaged in their functional abilities and lack of behavior problems, comparable in health, and exhibited comparable rates of change on these measures as adults with mental retardation due to other causes. Placement out of the parental home and parental death were predictors of change in health, functional abilities, and behavior problems.

    ABSTRACT: The AAIDD has promulgated various models of adaptive behavior, including its 1992 model stressing 10 adaptive skills and its 2002 model that highlighted three conceptual domains. In previous studies on the Adaptive Behavior Assessment System-II (ABAS-II), researchers found support for a model including both 10 adaptive skills and three conceptual domains. To extend this review, we examined gender-invariant structure of adaptive behavior using the ABAS-II Parent Form, Ages 5-21, to answer four questions: Do the skill areas in this measure display the same pattern of factor loadings and the same factor loadings? Are intercepts of the observed skill areas equal? Do skill areas measure the corresponding factors with the same accuracy? Results show a similar one-factor structure for males and females.

    ABSTRACT: Veridical and false pictorial recognition were assessed in individuals with mental retardation; groups were matched for MA and CA. Pictures were viewed in either a generative or static format at acquisition. The individuals with mental retardation and those in the MA-matched group had higher rates of false memories for critical items and lower hit rates than did their CA-matched peers. The mental retardation group demonstrated an acquiescent response bias (i.e., high novel false-alarm rate). When data were corrected for this bias, those with mental retardation had significantly lower hit rates but equivalent false-alarm rates to the MA-matched participants. Results are discussed in terms of pictorial distinctiveness and within the frameworks of activation monitoring and fuzzy trace theory.
