Abstract

Measures of fatigue, anxiety and depression were administered in self-report questionnaire format to a community-based sample of 2703 Australian twins aged over 50. Factor analysis indicated that a two-factor solution was appropriate and demonstrated a clear separation between fatigue-related items and questionnaire items relating to anxiety and depression. Highly congruent factor structures were derived for male and female subjects.
