Table 5

Means, standard deviations, minimum and maximum for all SRSDA subscales conceming their test, retest, average and difference between the two applications. The two columns to the right represent the division of the minimum and maximum difference to the standard deviation of the difference. It is desirable these values to be generally between ±2. It is obvious that some minor problems exist with melancholia and mania subscales
