The research presented here argues for the development of an evaluation tool for elderly persons' adjustment to a retirement home that more specifically measures the psychospatial adjustment of home residents. Elderly persons who enter a retirement home must undergo a process that requires them to first disappropriate their old objects and then reappropriate the new ones that furnish their rooms. The order in which this process occurs is as follows: first, objects from their former residence; second, objects acquired after entry into a home; and, third, objects belonging to the retirement home. After the existence of this process had been verified in a sample of 130 residents aged 67 to 98 years, it was demonstrated that the evaluation tool used in this study significantly correlates with the scale developed by Castonguay and Ferron (1999) that measures elderly persons' adjustment to their environments (EAPAR), as well as with the Geriatric Depression Scale (GDS), which evaluates levels of depression. In this study, this latter is an indicator of adjustment.
