This literature review was commissioned to understand the needs, preferences and experiences of people with mental health conditions and learning disabilities when accessing benefits, specifically Disability Living Allowance (DLA) and Attendance Allowance (AA). The main objectives of the review were to understand the existing evidence related to: needs and expectations; service provision and access; networks; and channel preferences. The Pension, Disability and Carers Service (PDCS) is keen to identify the particular needs of these groups and any barriers they may face when accessing PDCS services. This report presents the key findings and implications.
