The purpose of this study is to develop a self-administered version of the Health of the Nation Outcome Scales for Older Adults (HoNOS65+) in Spanish – the HoNOS65+A – and to study its reliability and validity.
There are two phases in the study: construction of the HoNOS65+A and the study of its psychometric properties. In the second phase, 179 users of 10 services for older people of Madrid were interviewed. They completed the HoNOS65+A, the Spanish version of the HoNOS65+, and other instruments that evaluate similar constructs. Reliability (internal consistency with the other-administered HoNOS65+, intraclass) and validity (concurrent, discriminant, and criterion validity) were analyzed.
High reliability indexes (intraclass correlation coefficients) were found for all the scales (HoNOS65+ and HoNOS65+A), except for items 4 and 6. Moreover, the HoNOS65+A has satisfactory concurrent (except 4, 6, and 9) and discriminant validity (except for items 4 and 10). Considering all these data and some theoretical points the items 4 and 6 have eliminated from the scale. Upon eliminating items 4 and 6, the analysis of the reliability (Cronbach's Alpha) and criterion validity (discriminant function among autonomous and assisted people) presents positive values.
The results indicate that the HoNOS65+A is a useful measure that does not assess a homogeneous area but instead different aspects of health and psychosocial functioning.
