Means and standard deviations are reported for the State-Trait Anxiety Inventory and the Zung Self-Rating Depression scale, collected during the course of a general health survey. Data for different age samples and for both sexes are presented for use in the evaluation of the significance of anxiety and depression levels in patients presenting with these symptoms. High estimates of reliability based on internal consistency statistics were found for all scales. Females scored more highly on both the measures and scores were inversely correlated with age, indicating the importance of specific and appropriate norms in assessing affective states.

Some general population norms for the Spielberger, Johnson et al. (1984) Anger Expression Scale (AX) are reported for a sample of over 1000 adults tested in a general health survey of a New Zealand community. Factor analysis confirmed the independence of the Anger/In and Anger/Out subscales, and the measure was found to have satisfactory levels of reliability.
