Measuring subjective complaints of attention and performance failures--development and psychometric validation in tinnitus of the self-assessment scale APSA.

ABSTRACT:

Background

Methods

This was a prospective, non-interventional, multicultural study.

The analysis included descriptive statistics of baseline data, item characteristics, test-retest reliability (intra-class correlation coefficients, ICC), definition of internal consistency (Cronbach' s alpha), and explorative and confirmatory factor analysis to define the structure of the scale.
