Life satisfaction of people with intellectual disability living in community residences: perceptions of the residents, their parents and staff members

Proxy-report in individuals with intellectual disability: A scoping review

BACKGROUND

Views can be collected from individuals (self-report) or others on their behalf (proxy-report).

OBJECTIVE

We aimed to review the literature on methods and statistical approaches used to evaluate observer versus self-report responses from individuals with intellectual disability or Down syndrome.

METHODS

A series of key questions related to statistical approaches and data collection methods were formulated a priori to inform the search strategy and review process. These addressed the topics of self-report in individuals with intellectual disability, including Down syndrome. Using the National Library of Medicine database, PubMed, detailed literature searches were performed. The quality of available evidence was then evaluated, the existing literature was summarised, and knowledge gaps and research needs were identified.

RESULTS

Fifty relevant original articles were identified which addressed at least one key question. Study details, including: research design, internal validity, external validity, and relevant results are presented. Review of studies of individuals with intellectual disability which used a variety of statistical approaches showed mixed agreement between self-report and proxy-report.

CONCLUSION

Few studies identified to-date have used self-report from individuals with Down syndrome, but lessons from the existing intellectual disability literature can guide researchers to incorporate self-report from individuals with Down syndrome in the future.

Using virtual reality to improve classroom behaviour in people with Down syndrome: An experimental study (Preprint)

Background

People with Down syndrome face various learning challenges. Introducing new and enjoyable experiences in learning settings may improve learning outcomes. Immersive and interactive technologies such as virtual reality can be used to deliver rich visual experiences in classrooms.

Objective

The aim of this study was to investigate the feasibility and benefits of virtual reality exposure for people with Down syndrome in learning settings.

Methods

To address this aim, we used a within-subjects design to assess the effect of a brief virtual reality drawing experience and conventional drawing experience on subsequent behavior in 16 participants.

Results

Large positive effects were found for virtual reality drawing (t₁₅=5.020, P<.001) and conventional drawing (t₁₅=3.720, P=.002) in improving subsequent behavior in a learning setting. Irrespective of the intervention, the participant’s mood, attention, and overall behavior significantly improved. No significant differences were found between the interventions (t₁₅=–0.648; P=.53).

Conclusions

This study’s results are encouraging for researchers and educators interested in using virtual reality for people with Down syndrome, as virtual reality was found to be highly feasible. Recommendations are made for researchers and educators interested in providing virtual reality experiences for people with Down syndrome.

Can the Vocal Expression of Intellectually Disabled Individuals Be Used as a Pain Indicator? Initial Findings Supporting a Possible Novice Assessment Method

Pain is difficult to assess in non-verbal populations such as individuals with intellectual and developmental disability (IDD). Due to scarce research in this area, pain assessment for individuals with IDD is still lacking, leading to maltreatment. To improve medical care for individuals with IDD, immediate, reliable, easy to use pain detection methods should be developed. The goal of this preliminary study was to examine the sensitivity of acoustic features of vocal expressions in identifying pain for adults with IDD, assessing their feasibility as a pain detection indicator for those individuals. Such unique pain related vocal characteristics may be used to develop objective pain detection means. Adults with severe-profound IDD level (N = 9) were recorded in daily activities associated with pain (during diaper changes), or without pain (at rest). Spontaneous vocal expressions were acoustically analyzed to assess several voice characteristics. Analyzing the data revealed that pain related vocal expressions were characterized by significantly higher number of pulses and higher shimmer values relative to no-pain vocal expressions. Pain related productions were also characterized by longer duration, higher jitter and Cepstral Peak Prominence values, lower Harmonic-Noise Ratio, lower difference between the amplitude of the 1st and 2nd harmonic (corrected for vocal tract influence; H1H2c), and higher mean and standard deviation of voice fundamental frequency relative to no-pain related vocal productions, yet these findings were not statistically significant, possibly due to the small and heterogeneous sample. These initial results may prompt further research to explore the possibility to use pain related vocal output as an objective and easily identifiable indicator of pain in this population.

Vocational Training in Virtual Environments for People With Neurodevelopmental Disorders: A Systematic Review

People with neurodevelopmental disorders are often considered unsuitable or incapable of working in open employment. When employment is available, tasks are often limited, and opportunities for career development are restricted. Policy and funding constraints leave people with disabilities without an opportunity to develop skills due to the additional time and costs for employers. To overcome these barriers, virtual environments have been proposed as a safe and reliable solution for training. An important prerequisite for a wider uptake of training in virtual environments are demonstrations that the training leads to improved performance in the real world. This is particularly true for people with neurodevelopmental disorders, as transferring learnings from one context to another can be challenging. A systematic review was conducted to assess whether training in virtual environments can be used to improve real-world vocational skills in people with neurodevelopmental disorders. After a systematic search in six databases, eight out of the initially identified 1,806 articles met the inclusion criteria. The findings from these eight studies demonstrate that people with neurodevelopmental disorders can transfer vocational skills from virtual environments to real-world settings. With substantial technological improvements, a surge in accessibility, and improved affordability, there is a need to build upon the promising results identified in this review.

Is it feasible to assess self-reported quality of life in individuals who are deaf and have intellectual disabilities?

PURPOSE

There is consensus that Quality of Life (QOL) should be obtained through self-reports from people with intellectual Disability (ID). Thus far, there have been no attempts to collect self-reported QOL from people who are deaf and have ID.

METHODS

Based on an established short measure for QOL (EUROHIS-QOL), an adapted easy-to-understand sign language interview was developed and applied in a population (n = 61) with severe-to-profound hearing loss and mild-to-profound ID. Self-reports were conducted at two time points (t₁ and t₂), 6 months apart. The Stark QOL, an established picture-based questionnaire, was also obtained at t₂ and three Proxy ratings of QOL (from caregivers) were conducted for each participant at t₁.

RESULTS

Self-reported QOL was successfully administered at both time points for 44 individuals with mild and moderate ID (IQ reference age between 3.3 and 11.8 years). The self-reports showed sufficient test-retest reliability and significant correlations with the Stark QOL. As anticipated, self-reported QOL was higher than proxy-reported QOL. Test-retest reliability and internal consistency were good for self-reported QOL.

CONCLUSION

Reliable and valid self-reports of QOL can be obtained from deaf adults with mild-moderate ID using standard inventories adapted to the linguistic and cognitive level of these individuals.

Staying connected during COVID-19: Family engagement with adults with developmental disabilities in supported accommodation

BACKGROUND

Enduring family engagement and informal support is crucial to the health and well-being of adults with developmental disabilities (DD) residing in supported accommodation. The COVID-19 pandemic and restrictive measures enforced in residential settings have resulted in changes in daily routine and modified the ways families can interact with and provide support to residents. Yet, the impact of these changes has not been empirically explored.

AIM

Explore how family caregivers have interacted with and supported their relatives with DD residing in supported accommodation during the pandemic.

METHODS

Changes in frequencies of communication modes and types of informal support were measured through a cross-sectional and anonymous online survey which completed by 108 family caregivers of adults with DD.

RESULTS

Most family caregivers adopted remote communication technologies; however, these were not perceived to be effective in filling the gap created by reduced face-to-face contact. While families were able to provide emotional support and advocacy using digital technologies, they were limited in their ability to provide significant social support.

CONCLUSIONS

Findings may help key stakeholders develop and implement novel strategies and policies to accommodate the changing circumstances and to ensure continuity of family engagement and informal support in the context of COVID-19.

Impact of the intellectual disability severity in the Spanish Personal Outcomes Scale

BACKGROUND

The interest in measuring quality of life (QoL) in persons with intellectual disability (ID) has brought about a number of QoL measurements for this population. These measurements need to address two issues that have contributed to enhancing the current instruments. First, the necessity to develop measures with adequate psychometric properties, which has been discussed in recent studies, and second, the agreement between experts in analysing objective and subjective perspectives, as well as the use of self-report to include the participation of the person with ID. The question that we set out to investigate in this paper is whether the measurements function properly for the person with ID, independent of their level of severity. We used the Spanish version of the Personal Outcomes Scale, as it is a psychometrically sound instrument and includes three sources of information (the person with ID, a professional and a family member).

METHOD

The sample was composed of 529 persons with ID (296 men, representing 55.95% of the total sample, and 233 women, with M_age  = 35.03, SD = 10.82) from several regions of Spain, along with their professional of reference and a family member. The severity variable was estimated for each item based on estimations of differential item functioning.

RESULTS

The results showed that several items were undervalued by the assessments if the severity of the ID was greater. Mainly, this difference was observed in the assessments by professionals and in the dimensions of rights, personal development and self-determination.

CONCLUSIONS

This paper focuses on the uses and interpretations of the results of the QoL measurements in the Personal Outcomes Scale. The results indicate that, in our sample, when people with high levels of ID are assessed, the functioning of some items are affected by the severity of this disability. For correct use, these items must be interpreted on the basis of the results obtained. Additionally, it is necessary to thoroughly review the QoL indicators for persons with severe or profound ID.

Behavior problems and health-related quality of life in Dravet syndrome

OBJECTIVE

Behavior problems in Dravet syndrome (DS) are common and can impact the lives of patients tremendously. The current study aimed to give more insight into (1) the prevalence of a wide range of specific behavior difficulties and aspects of health-related quality of life (HRQoL) in patients with DS compared with the general population (gp) and patients with epilepsy without DS, (2) the relations between these behavior problems and different aspects of HRQoL, and (3) the associations between seizure frequency, cognitive impairment (CI), behavior problems, and HRQoL, based on a conceptual model.

METHODS

One hundred and sixteen patients (aged between 2 and 67 years), affected by SCN1A-related seizures, were included in the study. Eighty-five were patients with DS, 31 were patients with epilepsy without DS. Behavior problems were measured using the Child/Adult Behavior Checklist (C/ABCL), HRQoL was measured using the Pediatric Quality of Life Inventory (PedsQL) Measurement Model. Other characteristics were obtained by clinical assessments, medical records, and semi-structured telephone interviews with parents. Comparisons between patients with DS, patients without DS, and the gp were calculated by the exact goodness of fit χ² analyses, relations between subscales were analyzed using Pearson's correlations, and the conceptual model was tested in a path analysis.

RESULTS

(1) Patients with DS show significantly more behavior problems compared with the gp and patients with epilepsy without DS. A total of 56.5% of patients with DS scored in the borderline and clinical ranges for total behavior problems. Problems with attention were most prevalent; 62.3% of patients with DS scored in the borderline and clinical ranges. Health-related quality of life was significantly lower for patients with DS compared with the gp and patients without DS. Physical and social functioning scores were especially low and decreased even more in the older age categories. (2) Problems with attention, aggression, and withdrawn behavior were most related to social functioning. Somatic problems and anxiety/depression were most related to emotional functioning. (3) Cognitive impairment and behavior problems were both independent predictors of poorer HRQoL in patients with DS, with behavior problems being the strongest predictor. Seizure frequency was only indirectly related to HRQoL, mediated by cognitive impairment.

IMPLICATIONS

The high prevalence of behavior problems in DS and the significant impact on quality of life (QoL), independent of epilepsy-related factors, emphasize the need for active management and treatment of these problems and should be considered as part of the management plan.

Living with family: perceptions of health and subjective well-being of adults with an intellectual disability

BACKGROUND

Little is known about the role of living circumstances to the perception of subjective well-being (SWB) and health of adults with intellectual disability (ID). The aim of the present study was to examine whether living circumstances impact differently on the perception of health and SWB and whether potential differences persist after accounting for other variables (e.g. level of support needs and reporting method).

METHODS

Secondary data analysis was undertaken of a large national survey of adults with an ID in England, aged 16 years and over. Participants were identified as living with family (N = 1528) or living out of home (N = 874).

RESULTS

The results of t-test and chi-square revealed that levels of health and SWB were perceived as being higher for people living with family than those living in out-of-home settings. Multiple linear regression analyses fitted to explore factors associated with these reported differences revealed that, when controlling for other variables, living with family was highly associated with reports of better SWB. Multiple logistic regression revealed that whilst the health status of people living with families were perceived as better, this was only true when their support needs were low. Poorest health outcomes were found for people with highest support needs who lived with family.

CONCLUSIONS

On the whole, the health and well-being of adults living with family were perceived more positively than those living out of home. However, potential health disparities exist for those with high support needs who live with family. Further longitudinal research is needed to explore causes and potential solution to these inequalities.

Item response theory analysis applied to the Spanish version of the Personal Outcomes Scale

BACKGROUND

The study of measurements of quality of life (QoL) is one of the great challenges of modern psychology and psychometric approaches. This issue has greater importance when examining QoL in populations that were historically treated on the basis of their deficiency, and recently, the focus has shifted to what each person values and desires in their life, as in cases of people with intellectual disability (ID). Many studies of QoL scales applied in this area have attempted to improve the validity and reliability of their components by incorporating various sources of information to achieve consistency in the data obtained. The adaptation of the Personal Outcomes Scale (POS) in Spanish has shown excellent psychometric attributes, and its administration has three sources of information: self-assessment, practitioner and family. The study of possible congruence or incongruence of observed distributions of each item between sources is therefore essential to ensure a correct interpretation of the measure. The aim of this paper was to analyse the observed distribution of items and dimensions from the three Spanish POS information sources cited earlier, using the item response theory.

METHOD

We studied a sample of 529 people with ID and their respective practitioners and family member, and in each case, we analysed items and factors using Samejima's model of polytomic ordinal scales.

RESULTS

The results indicated an important number of items with differential effects regarding sources, and in some cases, they indicated significant differences in the distribution of items, factors and sources of information.

CONCLUSIONS

As a result of this analysis, we must affirm that the administration of the POS, considering three sources of information, was adequate overall, but a correct interpretation of the results requires that it obtain much more information to consider, as well as some specific items in specific dimensions. The overall ratings, if these comments are considered, could result in bias.

Residential placement and quality of life for adults with severe autism spectrum disorders and severe-to-profound intellectual disabilities

Purpose

The purpose of this paper is to evaluate the relationship between some main characteristics of different living arrangements and the quality of life (QoL) of their users with severe intellectual disability and low-functioning autism spectrum disorders.

Design/methodology/approach

Study participants were assessed for ASD severity through the Childhood Autism Rating Scale or the Vineland Adaptive Behavior Scales (VABS): for behavioral problems with the aberrant behavior checklist (ABC); for perception of efficacy and satisfaction with care, through an adapted Visual Analogue Scale; and for QoL with the QoL inventory in residential environments (validated in French as Inventaire de la Qualité de Vie en Milieu Résidentiel). Because the goal was to define a “residential profile (RP),” the authors evaluated each participating residence with the Working Methods Scale and the questionnaire on residential parameters.

Findings

The RP allowed for the classification of the residences into three clusters. The authors found no clear relationship between QoL and the RP clusters, but the authors found the RP clusters to be significantly correlated with ABC factors F1 (irritability, agitation, crying) and F2 (lethargy, social withdrawal), and VABS scores for living, socialization, and motor skills.

Originality/value

RPs were more strongly correlated with ABC items and the ability to cope with everyday life than with QoL. The authors hypothesize that RP is correlated with both aberrant behavior and the autonomy of residents and that QoL remains relatively stable. Therefore, RP is correlated with the status of the residents; however, this appears not to be correlated with their QoL.

Does the severity of disability matter? The opinion of parents about professional support in residential facilities

BACKGROUND

Researchers have shown that the characteristics of a person with an intellectual disability (ID), in particular the severity of the disability, are related to the outcomes of professional support. Hardly any studies have asked parents and/or legal guardians for their own opinion about the quality of support given to their child/family member with ID. Therefore, this study examined the relationship between the severity of a person's disability and the opinions voiced by the parents and/or other legal guardians of that person concerning several aspects of the quality of support received in residential care.

METHOD

Questionnaires were completed by 1058 parents and/or legal guardians of people with ID living in residential facilities. A multiple covariance analysis was conducted to explore the relationship between the severity of the disability and the parents' and/or legal guardians' opinions.

RESULTS

Only small differences in the opinions about the quality of support were observed between parents and/or legal guardians of people with mild to moderate ID and those of people with severe to profound ID.

CONCLUSION

This study showed that there are differences in parental opinions about the quality of support, but that most of these differences are not related to the severity of disability. The only significant difference related to the severity of disability is on the leisure activities domain. Parents and/or legal guardians of a person with severe/profound ID were less satisfied with leisure activities than parents and/or legal guardians of persons with mild/moderate ID. It is important to determine to what other factors parental opinions are related, as these opinions concerning the quality of support are important measures alongside client self-reports and measures of the facility itself. The quality of support should be measured using a combination of methods for different stakeholders.

Human rights of children with intellectual disabilities: comparing self-ratings and proxy ratings

BACKGROUND

A child rights-based approach to research articulates well with Article 12 of the United Nations Convention on the Rights of the Child (CRC) and highlights the importance and value of including children's own views about aspects that concern them. The aim of this study is to compare children with intellectual disability's own ratings (as self-raters) to those of their primary caregivers (as proxy raters) regarding human rights of children. The study also aims to establish whether there is an inter-rater agreement between the self-raters and proxy raters concerning Maslow's hierarchy of needs.

METHOD

This study is nested in a larger study examining the human rights of children with intellectual disability in South Africa. In total, 162 children with intellectual disability from 11 schools across three provinces and their primary caregivers participated by answering parts of a Children's Rights Questionnaire (CRQ) developed by the researchers based on the United Nation's CRC. We compared the answers for six questions in the questionnaire that were addressed to self-raters (children) and proxy raters (primary caregivers) in the same way.

RESULTS

Questions regarding basic needs, such as access to clean water or whether the child had food to eat at home, were answered similarly by self-raters and proxy raters. Larger differences were found when self-raters and proxy raters were asked about whether the child had things or friends to play with at home. Socio-economic variables seemed to affect whether self-raters and proxy raters answered similarly.

CONCLUSION

The results underscore the importance of promoting children's rights to express themselves by considering the opinions of both the children as self-raters and their primary caregivers as proxy raters - not only the latter. The results indicate that it is especially important to include children's own voices when more complex needs are surveyed. Agreement between self- and proxy ratings could be affected by socio-economic circumstances.

Proxy and self-reported Quality of Life in adults with intellectual disabilities: Impact of psychiatric symptoms, problem behaviour, psychotropic medication and unmet needs

Proxies often underestimate the subjective Quality of Life (QoL) of adults with intellectual disability (ID). However, little is known about the reasons for these differences. Accordingly, the purpose of the present study is to, firstly, compare the self-reported QoL of adults with ID with proxy reports from staff of sheltered working and housing facilities, and, secondly, to identify possible differences of the impact of four potential predictor variables. Data of 102 adults with ID were collected as part of the MEMENTA study ('Mental health care provision for adults with ID and a mental disorder'). Results show that self-report QoL scores ranged from 72.6 to 86.8. Both proxies consistently reported lower QoL scores and agreement between self and proxy ratings was predominantly poor. Unmet needs and psychotropic medication were identified as the most important predictors of reduced self-rated QoL, whereas an increase of psychiatric symptoms, problem behaviours, and psychotropic medication best predicted the reduced QoL proxy ratings. To conclude, proxies still have to strive for a more holistic approach in surrogate QoL assessments and according to adults with ID, service providers should focus on a reduction of unmet needs and psychotropic medication to further improve QoL.

The Portuguese version of personal outcomes scale: a psychometric validity and reliability study

This article presents the results of a pilot study to evaluate the psychometric properties of the Escala Pessoal de Resultados (EPR), the Portuguese version of the Personal Outcomes Scale (POS), to assess quality of life (QOL) in people with intellectual disability (ID) in Portugal. We present the adaptation and validation processes of the EPR. Data were collected from 1,264 adults with intermittent and limited levels of support needs and respective proxies. Results of the research are discussed in requisites of the validity and reliability. The different coefficients illustrate that this scale may be a useful addition to the QOL assessment in Portuguese people with ID.

Sobrecarga familiar e crianças com transtornos do espectro do autismo: perspectiva dos cuidadores

OBJETIVO: avaliar a sobrecarga de familiares cuidadores de crianças com transtornos do espectro do autismo, segundo a percepção dos próprios cuidadores. MÉTODOS: participaram 20 sujeitos, de ambos os gêneros, com idades entre 22 e 60 anos (Média= 32,6), sendo dez familiares de crianças com transtornos do espectro do autismo e para compor o grupo controle dez familiares de crianças com transtornos de linguagem. As crianças apresentavam entre três e dez anos de idade (Média= 5,8). O grupo controle foi selecionado a partir do pareamento de idade, escolaridade e gênero das crianças. Todas as crianças encontravam-se em atendimento fonoaudiológico. Para avaliar a sobrecarga dos cuidadores foi utilizada a Escala Burden Interview e foram coletados dados sociodemográficos dos participantes. A análise estatística dos dados foi realizada a partir do teste de Mann-Whitney e da análise da Correlação Spearman (p< 0,05). RESULTADOS: a média do índice de sobrecarga do familiar cuidador de ambos os grupos foi 28, portanto, não foi observada diferença estaticamente significante e indicou que os G1 e G2 estavam moderadamente sobrecarregados. As características dos participantes também não foram significantes no índice de sobrecarga. CONCLUSÃO: cuidar de crianças com transtornos do espectro do autismo pode sobrecarregar seus familiares de modo semelhante ao de familiares de crianças com outros transtornos do desenvolvimento.

Eliciting perceptions of satisfaction with services and supports from persons with intellectual disability and developmental disabilities: a review of the literature

BACKGROUND

Assessing the perceptions of individuals with intellectual disability (ID) and developmental disabilities (DD) is an essential part of evaluating and planning services and an important component of respect for self-direction and autonomy. It can be difficult, however, to assess satisfaction in such a way that individuals with disabilities' actual perceptions of satisfaction are accurately represented because of intellectual and communication difficulties they may have, the restricted range and nature of service systems, and the limitations of strategies used by some researchers.

METHOD

The purpose of this literature review was to systematically examine research studies designed to solicit personal satisfaction information from individuals with ID and DD. We reviewed 29 studies that met inclusion criteria to determine (1) who were participants in the studies, (2) what processes researchers used to obtain opinions and perspectives of persons with ID and DD, and (3) how researchers ensured the credibility, accuracy and voluntariness of participants' responses.

RESULTS

Findings revealed that most of the research participants had ID with higher IQs and limited needs for supports. Researchers utilised a variety of processes to elicit perceptions of satisfaction. Most studies employed individual interviews; researchers addressed comprehensibility of questions in a number of ways (e.g. use of visuals, adjusting wording of questions, providing clear examples). Few studies reported training interviewers or taking into account participants' primary language or cultural background. No studies reported educating participants about how to understand the satisfaction information data or how to use it in advocating for more appropriate supports.

CONCLUSIONS

Assessing the satisfaction with supports and services of individuals with ID and DD is complex particularly for persons with extensive support needs. Continued research using varied conceptual frameworks and new technologies is needed. Also helpful will be teaching persons with disabilities about the assessment process and how to use its results.

Perceived burden and neuropsychiatric morbidities in adults with 22q11.2 deletion syndrome

BACKGROUND

22q11.2 deletion syndrome (22q11.2DS) is a common genetic subtype of intellectual disability (ID) remarkable for its constellation of congenital, developmental and later-onset features. Survival to adulthood is now the norm, and serious psychiatric illness is common in adults. However, little is known about the experiences and perceived needs of individuals with 22q11.2DS and their caregivers at time of transition from paediatric to adult models of care and beyond.

METHOD

We administered a mail survey to 84 caregivers of adults with 22q11.2DS and 34 adult patients themselves, inquiring about medical and social services, perceived burden and major challenges in adulthood in 22q11.2DS. Standard quantitative and qualitative methods were used to analyse the responses.

RESULTS

Fifty-three (63.1%) caregivers and 20 (58.8%) adults with 22q11.2DS completed the survey. Perceived burden was high, with psychiatric illness and/or behavioural issues considered the most challenging aspects of adulthood in 22q11.2DS by the majority of caregivers (70.0%) and many patients themselves (42.9%). Irrespective of the extent of ID and the presence or absence of other major features, caregivers expressed dissatisfaction with medical and social services for adults, including at time of transition from paediatric care.

CONCLUSIONS

To our knowledge, this is the first study to examine the subjective experiences of adults with 22q11.2DS and their caregivers and to identify their perceived needs for services. Better awareness of 22q11.2DS and its later-onset manifestations, early diagnosis and treatment of psychiatric illness, additional support at time of transition and dedicated clinics for adults with 22q11.2DS may help to improve patient outcomes and reduce caregiver burden.

Reliability of an assessment used in formal accommodation services: implications for adults with an intellectual disability

BACKGROUND

The Revised Irrabeena Core Skills Assessment (RICSA) is used in formal accommodation services and evaluates the functional skills of adults with an intellectual disability. The assessment is used to inform training for skills development. This study focused on establishing evidence for interrater reliability of the RICSA.

METHOD

The RICSA was completed by 101 staff members on 30 adults living in group homes. Interviews were conducted with 9 staff members in order to identify potential issues that may affect the reliability of the assessment. Interrater reliability was analysed using the intraclass correlation coefficient (ICC), and thematic analysis was conducted from the interview data.

RESULTS

The ICC values ranged from .63 to .73 across the 5 main domains of the RICSA.

CONCLUSIONS

The agreement found may be regarded as unsatisfactory given that the use of the RICSA is to inform skills training for people with an intellectual disability.

Self-reported health of people with intellectual disability

Self-reported health is an important outcome in the evaluation of health care but is largely ignored in favor of proxy-based reporting for people with an intellectual disability. This study briefly reviews the role of self-report in health assessment of people with intellectual disability and the challenges and recommendations that have emerged from the considerable body of research on interviewing and self-report. Limitations in current recommendations are addressed from the perspective of the cognition of self-report. The review describes conceptual directions for the reconciliation of the two contradictory themes in the treatment of self-report: the centrality given to personal perceptions and choices and the methodological concerns over the meaningfulness and validity of the self-reporting process.

Life satisfaction in persons with intellectual disabilities

We appraised life satisfaction using the Satisfaction with Life Scale (SWLS), and analysed its psychometric properties in persons with intellectual disability (ID). Ninety-nine persons with ID from four services in Spain participated. A battery of subjective assessments was used, including the SWLS, a Quality of Life measure (WHOQOL-BREF), and health status and sociodemographic information. Psychometric properties of the SWLS were investigated using standard psychometric methods. Overall, our results showed that persons with ID were satisfied with their life (SWLS score 25-29). Internal consistency (Cronbach's alpha) was .79. A factor analysis using principal components method, showed a one factor structure accounting for 55.7% of the variance. Associations, using Spearman's rho correlation coefficients, were confirmed between SWLS with the overall QoL, satisfaction with health and WHOQOL-BREF total score. Regarding 'known group' differences, persons living in residential institutions had lower life satisfaction compared to persons living in community facilities or living at home, though differences were not statistically significant. Student t-tests showed that SWLS scores significantly discriminated between healthy and unhealthy; and those reporting higher satisfaction with their relationships, home environment and their jobs compared to participants with lower satisfaction levels. To our best knowledge, this study is the first to report on the psychometrics properties of the SWLS in persons with ID, both in Spain and internationally. It might be a promising tool to use, with other outcome measures, in appraising persons with ID in different services and types of care; also, it might guide policymakers on the implementation of policies for persons with ID.

Care staff intentions to support adults with an intellectual disability to engage in physical activity: an application of the Theory of Planned Behaviour

Researchers suggest that people with an intellectual disability (ID) undertake less physical activity than the general population and many rely, to some extent, on others to help them to access activities. The Theory of Planned Behaviour (TPB) model was previously found to significantly predict the intention of care staff to facilitate a healthy diet in those they supported. The present study examined whether the TPB was useful in predicting the intentions of 78 Scottish care staff to support people with ID to engage in physical activity. Regression analyses indicated that perceived behavioural control was the most significant predictor of both care staff intention to facilitate physical activity and reported physical activity levels of the people they supported. Attitudes significantly predicted care staff intention to support physical activity, but this intention was not itself significantly predictive of reported activity levels. Increasing carers' sense of control over their ability to support clients' physical activity may be more effective in increasing physical activity than changing their attitudes towards promoting activity.

Comparing residential programmes for adults with autism spectrum disorders and intellectual disability: outcomes of challenging behaviour and quality of life

BACKGROUND

Owing to methodological issues, little research has been conducted to examine quality of life (QoL) as a treatment outcome in autism spectrum disorders (ASD) and intellectual disabilities (ID). This study was conducted to combine QoL measures and objective observations of challenging behaviours (CB) in order to evaluate changes over time in adults with ASD and ID who were treated in two different residential programmes; we hypothesised that a decrease in CB would be related to an improved QoL.

METHOD

In a longitudinal study (45 months), we followed 31 adults with ASD and ID who had been integrated into two residential programmes [Autism Programme with a Structured Method (PAMS) vs. traditional programme for ID (No-PAMS)] for 2-19 years. QoL [Quality of Life Inventory in a Residential Environment (IQVMR)] and severity of autistic features (Childhood Autism Rating Scales) were evaluated annually. CB, as measured by the Aberrant Behaviour Checklist (ABC), including stereotypic behaviour and inappropriate speech, were repeatedly assessed every 3 months.

RESULTS

Observed separately, the groups' results were different. In the PAMS programme, stereotypic behaviour and inappropriate speech (ABC scores) significantly decreased, and the IQVMR total score increased; in contrast, in the comparison group, ABC scores did not change and the IQVMR total score decreased. In all, three mixed-effect ANCOVAs partially confirmed that the PAMS programme had an effect on CB and that QoL improvement did not directly depend on the type of programme but on reducing CB as measured by the ABC.

CONCLUSION

The PAMS programme has a positive and indirect influence on QoL by reducing CB.

Phenotype-environment interactions in genetic syndromes associated with severe or profound intellectual disability

The research literature notes both biological and operant theories of behavior disorder in individuals with intellectual disabilities. These two theories of genetic predisposition and operant reinforcement remain quite distinct; neither theory on its own is sufficient to explain challenging behavior in genetic syndromes and an integrated approach is required. This literature review integrates the two approaches by exploring how environmental factors can influence problem behavior in genetic syndromes associated with intellectual disability. Particular attention is paid to studies that describe evidence that problem behaviors in syndromes that are considered to be phenotypic are associated with other aspects of an established behavioral phenotype. The review highlights how the study of phenotype-environment interactions within syndromes can promote understanding of the aetiology of problem behaviors both within genetic syndromes and, ultimately, the wider population of individuals with severe intellectual disabilities. The review also evaluates the current status of research and the methods typically employed. Implications for intervention, future research and extending existing causal models of challenging behavior are discussed.

Evaluating the inter-respondent (consumer vs. staff) reliability and construct validity (SIS vs. Vineland) of the Supports Intensity Scale on a Dutch sample

BACKGROUND

Despite various reliability studies on the Supports Intensity Scale (SIS), to date there has not been an evaluation of the reliability of client vs. staff judgments. Such determination is important, given the increasing consumer-driven approach to services. Additionally, there has not been an evaluation of the instrument's construct validity on a non-English speaking sample. This is important as the SIS is currently translated into 13 languages.

METHOD

Data were collected in two different samples, using the Dutch translation of the SIS and the Vineland-Z.

RESULTS

There was a significant correlation between ratings of staff and consumers on the SIS; however, the relationship between the mean scores of consumer and staff responses indicated significant differences in staff and consumer scores. All correlations between the Vineland-Z domains and the SIS subscales were significant and negative, ranging from -0.37 to -0.89.

CONCLUSIONS

Analyses of the inter-respondent reliability suggest that one needs to consider the source of information regarding needed supports carefully. The significant negative correlations between SIS and Vineland-Z reflect that the SIS is measuring a different construct (needed support) than the Vineland-Z (adaptive behaviour). The results of the two studies provide additional support for the etic (universal) properties of the SIS, as both hypotheses were confirmed. In conclusion, SIS users are provided with a wealth of information that can be used for multiple purposes.

A qualidade de vida de pessoas com deficiência mental leve

Não é prática comum dar voz a pessoas com deficiência, mesmo quando se trata da investigação de sua própria qualidade de vida. Assim, este estudo teve por objetivo conhecer a opinião de 15 adultos com deficiência mental leve em relação a sua qualidade de vida e a opinião de seus cuidadores também a esse respeito, por meio de um instrumento que avalia a qualidade de vida (WHOQOL-Bref). Os dados foram analisados estatisticamente e comparados. Os resultados mostram que a diferença entre as avaliações foi pequena nas questões referentes à satisfação com os domínios físico, psicológico, das relações sociais e do meio ambiente. A avaliação feita pelas pessoas com deficiência foi apenas ligeiramente superior àquela feita por seus cuidadores. Não houve diferença estatisticamente significativa entre as avaliações, do que se conclui que as pessoas com deficiência mental são capazes de falar de suas próprias vidas de maneira positiva e bastante realista.

Day service programmes for people with a severe intellectual disability and quality of life: Parent and staff perspectives

This study focuses on the contributions of a community and campus based day programme to the quality of life of programme participants with a severe level of intellectual disability from the perspective of parents and staff. Qualitative interviews were carried out with parents and staff to explore the contribution that the two programmes had to participants' quality of life in the 6 months since the community based programme began. Schalock and Keith's Quality of Life Questionnaire was administered to supplement the qualitative data. Results indicated that the community based programme contributed more to participants' quality of life over the preceding 6 months than the campus based programme. This study revealed that community based participants' new-found social roles, their hobbies and their work opportunities had a positive effect on their quality of life.

Quality of life of adults with pervasive developmental disorders and intellectual disabilities

The purpose of this study was to observe quality of life (QoL) and global evolution of persons with Pervasive Developmental Disorders (PDD) in three different groups. Individualized programs for PDD were compared to traditional programs for intellectual disabilities. Behavioural disorders were repeatedly evaluated using the Aberrant Behaviour Checklist (ABC) and QoL once a year. Little research has investigated this domain due to methodological problems with a non-verbal population. Two preliminary studies of individualized programs showed a significant reduction in behaviour disorders over the course of the study. The recent inclusion of a control group indicates that a traditional program reduces lethargy/social withdrawal (ABC factor 2). A good QoL was measured for the three groups.

Translating policy principles into practice to improve health care access for adults with intellectual disabilities: A research review of the past decade

This article extracts principles from two Surgeon General reports, Closing the Gap: A National Blueprint to Improve the Health of Persons with Mental Retardation (2002) and Call to Action to Improve the Health and Wellness of Persons with Disabilities (2005), and combines them with the Objectives from Chapter 6 of Healthy People 2010 to create a policy framework. This framework is used to review literature from the past decade on access to health care and health promotion for persons with intellectual and developmental disabilities (IDD). Review of the literature indicates an emerging evidence base for health promotion programs for persons with IDD. Research in health care and health promotion access requires improvements in surveillance and measurement of quality of life, as well as increased participation of persons with IDD and their families in its implementation. While international guidelines for primary health care have been developed for people with IDD, US guidelines are specialty focused and address specific conditions. Despite its recognized importance, there is surprisingly little information on training programs for health care providers to improve care of persons with IDD. Financing of health care continues to threaten access to comprehensive care for persons with IDD, particularly regarding coordination of care and availability of providers who accept Medicaid patients. Community-based sources of health care have been slow to emerge, and there is clear need for assumption of responsibility for providing care to persons with IDD. Future US policy should include consideration of environmental factors in health care access.

A cascade of disparities: Health and health care access for people with intellectual disabilities

People with ID represent approximately 2% of the population and, as a group, experience poorer health than the general population. This article presents recent conceptualizations that begin to disentangle health from disability, summarizes the literature from 1999 to 2005 in terms of the cascade of disparities, reviews intervention issues and promising practices, and provides recommendations for future action and research. The reconceptualization of health and disability examines health disparity in terms of the determinants of health (genetic, social circumstances, environment, individual behaviors, health care access) and types of health conditions (associated, comorbid, secondary). The literature is summarized in terms of a cascade of disparities experienced by people with ID, including a higher prevalence of adverse conditions, inadequate attention to care needs, inadequate focus on health promotion, and inadequate access to quality health care services. Promising practices are reviewed from the perspective of persons with ID, providers of care and services, and policies that influence systems of care. Recommendations across multiple countries and organizations are synthesized as guidelines to direct future action. They call for promoting principles of early identification, inclusion, and self-determination of people with ID; reducing the occurrence and impact of associated, comorbid, and secondary conditions; empowering caregivers and family members; promoting healthy behaviors in people with ID; and ensuring equitable access to quality health care by people with ID. Their broadscale implementations would begin to reduce the health disparity experienced by people with ID.

Inter-rater reliability of the Pennsylvania independent monitoring for quality program's essential data elements scale

The purpose of the independent monitoring for quality (IM4Q) program is to bridge communication between individuals with mental retardation and the service providers on whom they rely. The IM4Q program uses an interview (essential data elements survey) to gather information about the lives of individuals with mental retardation. Collaboration between individuals with mental retardation, family members, and community members provides diverse interviewing teams. This study evaluates inter-rater reliability of the essential data elements (EDE) survey. Findings show that 73 of the 74 questions had monitor agreement scores of 85% or higher Inter-rater reliability of the Pennsylvania independent monitoring for quality program's essential data elements scale.
