Few Quality of Life (QoL) measures tap into the concept of capability, i.e. genuine opportunities to 'do' and 'be' the things that a person deems important in life. The ICECAP-O is one such instrument. This presentation includes test-retest reliability, item relevance, face- and content validity, and accessibility of the ICECAP-O in a Swedish context. Thirty-nine 70-year-olds who took part in a population-based study completed the Swedish version of the ICECAP-O on two occasions, and another 18 partook in cognitive interviews. Test-retest reliability was analyzed for the index and separate items, and participants rated item relevance on a Visual Analogue Scale. A standardized classification scheme was used to quantify any identified response problems, and a thematic analysis was applied to capture participants’ experiences of completing the measure and perceptions of included attributes. Test-retest showed that the index score had good stability, ICC of 0.80 (95 % CI 0.62-0.90). However, Kappa was low for each separate item, and ranged from 0.18 (Control) to 0.41 (Role). Participants gave their highest relevance rating to Attachment and the lowest to Enjoyment. In the cognitive interviews, three participants (18%) had problems completing ICECAP-O, and out of 80 question segments, judged problems occurred for five (6%). Most participants perceived the attributes as understandable even though the meaning of Control brought some uncertainty. ICECAP-O has potential for becoming a valuable addition to the supply of QoL measures in research and health and social care in Sweden. However, we recommend further research on more diverse groups of older person.
