Abstract Background Aging has determined a demographic shift in the world which is considered a major societal achievement and a challenge. Aging is primarily a subjective experience shaped by factors such as gender and culture. There is a lack of instruments to assess attitudes to aging adequately.

This paper aims to develop and validate a reliable attitude to aging instrument by combining classical psychometric approach and Rasch analysis. Methods Pilot study and field trial are described in details. Statistical analysis .
