ZUNG: Zung Self-rating Depression Scale

0.00

Questionnaire for Depression

This scale (Zung, 1965) may give an indication of the degree of depression. The list consists of 20 statements that each relate to a specific characteristic of depression. With each statement it must be indicated to what extent the statement applies to the person during the last 2 weeks. Answers are given on a Likert scale with 4 points. The answer alternatives range from “rarely or never” to “almost always or always”. There are norms from 154 healthy adults and from 50 psychiatric patients. These norms are divided into 5 classes, ranging from “HIGH” to “VERY LOW”. The list is also available in English.
