This study addresses development of a content-valid cross-Nordic version of the Housing Enabler and investigation of its inter-rater reliability when used in occupational therapy rating situations, involving occupational therapists, clients, and their home environments. The instrument was translated from the original Swedish version of the Housing Enabler, and adapted according to accessibility norms and guidelines for housing design in Sweden, Denmark, Finland, and Iceland. This iterative process involved occupational therapists, architects, building engineers, and professional translators, resulting in the Nordic Housing Enabler. For reliability testing, the sampling strategy and data collection procedures used were the same in all countries. Twenty voluntary occupational therapists, pair-wise but independently of each other, collected data from 106 cases by means of the Nordic Housing Enabler. Inter-rater reliability was calculated by means of percentage agreement and kappa statistics. Overall good percentage agreement for the personal and environmental components of the instrument was shown, indicating that the instrument was sufficiently reliable for application in practice and research in the Nordic context. The varying kappa results highlight the need for further study in order to understand the influence of prevalence more profoundly, which should be kept in mind when interpreting the results.

An agency-centred approach could produce new theoretical ideas and practical implications for developing older adults' rehabilitation to better meet their needs as well as the goals of group-based rehabilitation interventions.

The article contributes to the discussion of how older adults' rehabilitation should be reformed within the Finnish context. The study suggests that a person-centred gerontological rehabilitation process should be conceptualized in terms of an agency-based approach with a personally constructed and temporally embedded life-course perspective. This kind of conceptualizing could promote empowered cooperation and innovative interventions with flexible schedules in the rehabilitation processes of older adults.
