“…in Sweden € 83m in 2002) (Boverket, 2003) only few evaluations have been conducted, focusing, for example, on functional status among frail elderly persons (Mann et al, 1999), or on the relationship between lung capacity and housing conditions among younger adults with asthma (Frisk et al, 2002). Furthermore, cross-sectional studies do not provide sufficient knowledge useful for describing rehabilitation processes over time, indicating that longitudinal evaluations are imperative in order to describe the direction, magnitude, and pace of change (Gitlin et al, 2001;Golant, 2003). However, longitudinal evaluations of housing adaptations have not been conducted, and to date systematic, research-based strategies for such evaluations are lacking.…”
