A number of studies involving staff working in services for people with intellectual disabilities have utilised equity theory as a theoretical framework. According to this theory, people evaluate social relationships through the comparison of inputs and outcomes, respectively, with what a person brings to and receives from a relationship. Little is known about what constitute inputs and outcomes for staff working in services for people with intellectual disabilities. Semi-structured interviews were conducted with 15 staff to find out what constitute inputs and outcomes for staff who work with people with intellectual disabilities. The interviews were conducted in the first half of 2008 in the United Kingdom. Data were analysed using template analysis. A wide range of inputs and outcomes was identified by staff, which were grouped under high-level themes relating to relationships with their employers, their co-workers and the service users. The utility of the findings, in terms of informing future research, is discussed.
