Psychometric evaluation of the Danish version of Satisfaction with Daily Occupations (SDO)

Aims: The Satisfaction with Daily Occupations (SDO) scale assesses satisfaction within the domains of work, leisure, domestic tasks, and self-care. The aim was to investigate the psychometric properties of the Danish version of the SDO when used with asylum seekers. Methods: The participants were 93 Danes without known ill health and 43 asylum seekers. They completed the SDO and rated their perceived health, activity level, and general satisfaction with daily occupations. Translation into Danish and back-translation into Swedish was made by professional interpreters. Results: Internal consistency was a = 0.75 for the Danish sample and a = 0.79 for the asylum seekers. The SDO distinguished between asylum seekers and the Danish sample, suggesting criterion validity. Concurrent validity, analysed against general satisfaction with daily occupations, was indicated for both samples. Discriminant validity was indicated against self-rated health for both samples and against activity level for the Danish sample. There was, however, a correlation of 0.65 between the SDO satisfaction score and activity level for the asylum seekers. Conclusion: The SDO exhibited satisfactory internal consistency and criterion and concurrent validity. The findings regarding discriminant validity were somewhat inconclusive. The Danish SDO may be regarded as psychometrically sound but further psychometric testing is needed.
