Today Italy is one of the countries with the highest levels of longevity, but residential facilities for elderly adults need to be developed yet. The present contribution concerns a research project still in progress that focuses on the topic of change of residence in old age, either temporarily or for longer periods. The aim of the study is to analyze and to compare the elderly’s experience of residential relocation with reference to different type of structures such as sheltered houses, geriatric healthcare structures, hospitals, and healing centres as thermal centres and beauty farms. The conceptual frame of reference is the Complementary-Congruence Model of person-environment fit (Carp & Carp, 1984) that is based on Murray’s (1938) notion that adaptation depends on satisfaction of personal needs by the environment. This model tries to explain relevant changes in person-environment relationship during the life-span, with particular attention to the processes of ageing. Starting from this model, the purpose of the present project is to identify the role of some psychological and socio-physical dimensions as determinants of the attitudes towards environmental changes. Such dimensions include relocation motivations, differentiated between content (person, physical environment, social environment, other external or societal) and level of need (basic needs, anticipated basic needs, higher-order needs, strategies of coping (i.e., assimilative vs. accommodative), environmental competence, residential satisfaction, perception of control on the environment, personal or collective identity, psychological well-being, attachment to places, quality of socio-physical environments (in terms of architectural and socio-physical features of residential settings such as level of humanization, presence of affordances, restorative potential, level of stimulation and coherence, etc.), situational factors (e.g., life events), and place of living (i.e., urban vs. rural). Specific attention will be paid to the role of the intentional choice of environmental mobility and of temporal perspective to characterize the complex experience of environmental change in old age. The research schedule will include a) a preliminary focus group, in order to gather useful information for the following phases, b) a survey study, whose participants will be approximately 200 over-65 aged individuals living independently alone or with a spouse, in both urban and rural contexts, c) a field study to be carried out in different types of residential structures, in order to investigate the actual experience of environmental change in the shift from the old to the new setting (about 100 participants are expected), and d) an experimental study (with about 80 participants) to investigate the strength of implicit attitudes and beliefs regarding the relocation experiences. Validated tools or ad hoc adaptation of pre-existing scales will be used for measuring the investigated dimensions. Expected results are the significant correlations between: intentionality of environmental mobility and residential satisfaction; tendency to use assimilative coping strategies and positive attitude to relocate; context of provenience and level of autonomy, psychological well-being, social network, preponderance of personal or collective identity and attitude to relocate; level of humanization of the residential setting of destination, attitude to relocate and residential satisfaction; intentional choice and attachment to places; length of environmental change and attach- ment to places; level of residential mobility during past years and attachment of elderly people to their home. It is also expected the mediating role of environmental competence in the relationship between motivation and attitude to relocate. Outcomes of the present research can be useful to add empirical knowledge about relevant dimensions that influence decisions on relocation in elderly adults.
