Background Subjective wellbeing (SWB) in people with intellectual disabilities has been the focus of increased interest in the identification of support needs and as an outcome measure for interventions and service delivery evaluations. It is therefore important to conduct further research in this area, and to develop appropriate scales to measure SWB.
Methods A new scale, the Personal Wellbeing Index-Intellectual Disability (PWI-ID) was administered to 114 adults with mild (n = 82) or moderate (n = 32) level ID in Victoria, Australia.
Results The PWI-ID demonstrated good reliability and validity. A comparison of the findings with previous research indicates that participants’ SWB levels are within the normative range, and are similar to those reported by the general population.
Conclusions The results support the notion that individuals with ID do not experience life quality lower than normal, which can be explained theoretically by the Theory of Subjective Wellbeing Homeostasis. The use of the PWI-ID may ultimately assist in ensuring that the needs of people with ID are being met and inform the planning and delivery of congruent resources and services.
