A self-rating depression scale.

Abstract: The fact that there is a need for assessing depression, whether as an affect, a symptom, or a disorder is obvious by the numerous scales and inventories available and in use today. The need to assess depression simply and specifically as a psychiatric disorder has not been met by most scales available today. We became acutely aware of this situation in a research project where we needed to correlate both the presence and severity of a depressive disorder in patients with other parameters such as arousal response during sleep and changes with treatment of the depressive disorder. It was felt that the general depression scales used were insufficient for our purpose and that the more specific scales were also inadequate. These inadequacies related to factors such as the length of a scale or inventory being too long and too time consuming, especially for a patient

Self-Rating Depression Scale in an Outpatient Clinic: Further Validation of the SDS

Abstract: RECENT development and use of the Self-Rating Depression Scale (SDS) has Proven to be a valuable tool in the assessment of depressive disorders in a group of hospitalized inpatients. 1 There is a similar need in outpatient clinics to quantitate the amount of depressive symptomatology present or absent in the patients seen for treatment. Depressive symptoms may be present in any of the psychiatric disturbances seen in such a clinic, and a diagnosis of depressive disorder must still be made on a clinical basis. However, the use of such a scale is valuable in documenting and quantitating initial symptoms and complaints, and following changes in the patient's clinical course subsequent to treatment, using any of the modalities available. The purpose of a self-rating depression scale to be used in such an outpatient clinic setting would be similar to the ones stated previously with respect to its

Some norms and reliability data for the State--Trait Anxiety Inventory and the Zung Self-Rating Depression scale.

Abstract: 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.

Validity of the Zung Self-rating Depression Scale.

Abstract: The Zung Self-rating Depression Scale (ZSDS) correlated well (0.69) with the treating physician's global rating in 26 depressed out-patients during the six weeks of treatment with a tricyclic anti-depressant. In a larger sample of 41 patients, a high correlation was found between the ZSDS and the Hamilton Rating Scale. The sensitivity of the ZSDS was found to be adequate. The scale was able to differentiate, at the 0.05 level, four severity groups classified on the basis of the global rating. The importance of the direct relationship between the range of severity studied and the value of the correlation coefficient was discussed. Previous investigations and the results of this study indicate that the ZSDS is a valid and sensitive measure of clinical severity in depressed patients and support its continued use as a research instrument.
