The aims of this quasi-experimental study were to determine whether Australians aged 65 years and older, who participated in the nationwide Exercise Right for Active Ageing program experienced a change in physical function, and to identify factors associated with this change. For participants who comp...
Not all residents and not all care homes had received the i-CGA intervention by the time of this interim analysis, thus allowing for a quasi-experimental analysis. Finally, one limitation is that it is unclear whether the mortality differences are a result of receiving CGA and/or of having ...
Aim: Investigating the effect of an educational intervention on PLHIV's strategies to cope with HIV. Methodology: Quasi-experimental, before-and-after study type, whose data were collected before and after educational intervention, was carried out with 75 PLHIV at a School Outpatient Clinic. The ...
