RESUMO
BACKGROUND: Physical-activity approaches for people with intellectual disabilities (ID) are more likely to be effective and sustainable if they also target direct support professionals' behaviour. However, no tools to measure the behavioural determinants for direct support professionals are available as of yet. This study aims to construct a self-report tool to measure direct support professionals' behavioural determinants in physical-activity support for people with ID and to analyse its psychometric properties. METHODS: The tools' sub-scales and items corresponded with a proposed conceptual model. A pilot study was carried out to investigate and improve content validity. Construct validity and measurement precision were examined using item response theory models with data from a convenience sample of 247 direct support professionals in the support of people with ID. RESULTS: Results supported the three theory-driven behaviour scales and indicated reasonable to good construct validity. The marginal reliability for the scales ranged from 0.84 to 0.87, and adequate measurement precision along the latent continua was found. CONCLUSIONS: The tool appears to be promising for measuring the behavioural determinants of direct support professionals for the physical-activity support of people with ID and has potential as a tool for identifying areas to focus on for interventions and policies in the future.

BACKGROUND: People with severe or profound intellectual and motor disabilities (SPIMD) encounter several risk factors associated with higher mortality rates. They are also likely to experience a cluster of health problems related to the severe brain damage/dysfunction. In order to earlier detect physical health problems in people with SPIMD, first of all, knowledge regarding the prevalence of physical health problems is necessary. The aim of this systematic review was to methodically review cross-sectional studies on the prevalence of various types of physical health problems in adults with SPIMD. METHOD: MedLine/PubMed, CINAHL, Embase, PsycINFO and Web of Science were searched for studies published between 2004 and 2015. The quality of the incorporated studies was assessed utilising an adjusted 'risk of bias tool' for cross-sectional studies. To estimate the prevalence of the health problems, the proportion and corresponding confidence interval were calculated. A random effect meta-analysis was performed when at least three studies on a specific health problem were available. RESULTS: In total, 20 studies were included and analysed. In the meta-analysis, a homogeneous prevalence rate of 70% (CI 65-75%) was determined for epilepsy. Heterogeneous results were ascertained in the meta-analysis for pulmonary/respiratory problems, hearing problems, dysphagia, reflux disease and visual problems. For the health problems identified in two studies or in a single study, the degree of evidence was low. As expected, higher prevalence rates were found in the current review compared with people with ID for visual problems, epilepsy and spasticity. CONCLUSION: This review provides an overview of the current state of the art research on the prevalence of health problems in adults with SPIMD. There is a substantial need for comprehensive epidemiological data in order to find clusters of health problems specific for people with SPIMD. This would provide insight into the excess morbidity associated with SPIMD.
