Introduction:

The aging of the Cuban population brings about an increase in disability. In this sense, the International Classification of Functioning, Disability and Health recommends the design of measurement instruments to identify environmental factors affecting functionality.

Objective:

To describe, in terms of face, content and construct validity, the psychometric properties of a measurement instrument designed to identify environmental barriers perceived by elderly people in the Cuban context.

Methods:

A technological development study was carried out. A group of experts was consulted for the face and content validation, while the unbiased and corrected content validity coefficient was calculated. For construct validity, principal component factor analysis was calculated.

Results:

The unbiased and corrected content validity coefficient showed figures above 0.80, considered as good. Factor analysis yielded seven factors that explain the dimensions explored in the definition intended to be measured.

Conclusions:

The designed instrument showed high agreement among the experts in terms of face and content validity. The indicators showed that the instrument has a multidimensional structure that corresponds to the construct that it is intended to measure.
