Validity testing of the quality of life scale, Swedish version: focus group interviews of women with fibromyalgia.

Focus group interviews were used to examine validity of the Quality of Life Scale, Swedish version (QOLS-S) for use with women with fibromyalgia. Five interviews with 18 women with fibromyalgia were completed. The opening question was "What does quality of life mean to you?" Later, participants were asked to respond to questions about the specific domains and items in the QOLS-S. The transcribed interviews were analysed, and categories were identified. Opinions concerning domains and items in the QOLS-S were linked to domains of the QOLS-S. Four categories emerged from the opening question: finances, to be an active person and participate in society, relations with others, and health. Overall, the women's perceptions of quality of life were congruent with the domains of QOLS-S. However, further attention should be given to the translation of certain items and apparent overlaps in some items indicate that they can be combined. Also, the instrument needs to be scrutinized from a cultural perspective because some items in the "social, community and civic activities" domain were not endorsed by the participants.
