RESUMEN
BACKGROUND: We examined the influence of the organizational environment on challenging behaviour in people with intellectual disabilities to increase understanding of the quality of support services for people with intellectual disabilities. METHOD: Twenty-one professionals and managers from four specialized Dutch disability service organizations were interviewed. Data were analysed with a grounded theory approach, using Bronfenbrenner's ecological theory as a sensitizing frame. RESULTS: The organizational environment (i.e., vision, values, sufficient resources) is related via the support service (i.e., providing stability, constant awareness) to residents' challenging behaviour and is also linked directly to challenging behaviour (e.g., living environment, values). Organizations are restricted by national regulations, negative media attention and changing societal values, which negatively influence quality of support. CONCLUSIONS: The creation of a supportive organizational environment for staff, who in turn can provide quality support services to residents with demanding care needs, was found to prevent challenging behaviour in people with intellectual disabilities.
