An analysis of anxiety and depression scales.

The relationship between the constructs of anxiety and depression are examined through the administration of nine self-report scales to male and female undergraduates. The results showed strong correlations among all measures, and factor analyses revealed one major "psychological distress" factor for each sex. No sex differences were found on the measure employed. The discussion focused on the implications of the findings for research in the areas of anxiety and depression, and further research that is required.
