Background:
There is a paucity of adequate and validated instruments for the measurement of successful aging for geriatric researchers in Chile.
Aim:
To validate the Successful Aging Inventory (SAI) in Chilean older people.
Material And Methods:
SAI was answered by 777 older people aged 70 ± 7 years (63% women) living in urban and rural areas, including the highlands of a Northern desert region of Chile.
Results:
A Cronbach alfa of 0.92 was obtained for the general dimension of successful aging. The figures for each dimension included in the theoretical model (functional performance, intrapsychic factors, gero-transcendence; spirituality; purpose and life satisfaction), and ranged from 0.66 to 0.91. Confirmatory factorial analysis showed that the original inventory model, fits with the data collected from Chilean people.
Conclusions:
Successful Aging Inventory (SAI) is a reliable and adequate inventory, which can be used in Chilean older people.
