RESUMEN
In this paper, we extend the linear M-quantile random intercept model (MQRE) to discrete data and use the proposed model to evaluate the effect of selected covariates on two count responses: the number of generic medical examinations and the number of specialised examinations for health districts in three regions of central Italy. The new approach represents an outlier-robust alternative to the generalised linear mixed model with Gaussian random effects and it allows estimating the effect of the covariates at various quantiles of the conditional distribution of the target variable. Results from a simulation experiment, as well as from real data, confirm that the method proposed here presents good robustness properties and can be in certain cases more efficient than other approaches.

BACKGROUND: Community-based rehabilitation (CBR) programmes have been described as highly effective means of promoting the rights and opportunities of persons with disabilities (PwD). Although CBR is often the main way in which PwD in low-income and middle-income countries access rehabilitation services, there is little literature providing rigorous evaluation of their impact on people's well-being. METHODS: Data were collected in the Mandya and Ramanagar districts (Karnataka state, India), between December 2009 and May 2010. In total 2540 PwD were interviewed using stratified random sampling: 1919 CBR beneficiaries (who joined the programme between 1997 and 2009) and 621 persons who were living in villages not covered by the programme. We controlled for the systematic differences between people joining and not joining the programme using the propensity score matching method controlling for covariates at individual and village level. We evaluated the impact of the programme on the subgroups of PwD who are disadvantaged on the dimensions of interest: access to pensions, use of aid appliances, access to paid jobs and improvement in personal-practical autonomy after 4 and 7â years of joining the CBR. RESULTS: We observed a positive and significant impact of the programme on access to services, rights and opportunities of PwD. The results indicate that compared with the control group access to pensions and allowances, aid appliances, access to paid jobs and personal-practical autonomy increased by 29.7%, 9.4%, 12.3% and 36.2%, respectively, after 7â years. CONCLUSIONS: The CBR programme analysed has a positive impact on access to services and the well-being of PwD who are particularly deprived on outcomes of interest.

PURPOSE: In this paper, we measure the effectiveness of Community-Based Rehabilitation (CBR) programmes in promoting the well-being of people with disabilities and removing the barriers to their participation in family and community decision-making processes. METHOD: To evaluate the impact of the CBR programme, we use data from a large-scale control study in Karnataka, India. Propensity score matching is used to evaluate the impacts on disabled persons after 2, 4 and 7 years of entering the CBR. The theoretical framework for the analysis is based on the CBR guidelines, which are combined with the International Classification of Functionings (ICF), the United Nations Convention on the Rights of People with Disabilities (UN CRPD) and Amartya Sen's capability approach. RESULTS: CBR has a positive impact on the well-being of persons with disabilities participating in the programme and particularly on their participation within the family and the society at large. CONCLUSIONS: CBR programmes have a multidimensional and positive impact on individual and collective capabilities; on individual, agency and social empowerment. Implications for Rehabilitation Community-Based Rehabilitation (CBR) can make a lasting difference in the life of persons with disabilities. CBR improves participation and inclusion of persons with disabilities in the family and in the community.
