What does the CES-D measure?
Description of Measure: The Center for Epidemiological Studies-Depression (CES-D), originally published by Radloff in 1977, is a 20-item measure that asks caregivers to rate how often over the past week they experienced symptoms associated with depression, such as restless sleep, poor appetite, and feeling lonely.
How are CES-D scores calculated?
The Total CESD-R Score is calculated as a sum of responses to all 20 questions. In order to make the revised CESD-R have the same range as the original version i.e., the ‘CESD style score’), the values for the top two responses are given the same value: Not at all or less than one day = 0. 1-2 days = 1.
What is the CES-D 10?
Centre for Epidemiological Studies Depression Scale (CES-D-10) The CES-D-10 is a 10-item Likert scale questionnaire assessing depressive symptoms in the past week . It includes three items on depressed affect, five items on somatic symptoms, and two on positive affect.
How many questions did those who developed the CES-D’r originally consider including in this scale?
As in the original CESD the range of possible scores is between 0 (for those who say ‘not at all or less than one day to all 20 questions’ and 60 (for those who say ‘5-7 days’ or ‘nearly every day for 2 weeks’ for all 20 questions).
Who invented the CES-D?
The original CES-D as developed by Radloff in 1977 contains 20 items, four of which are reverse coded. Reverse-coded items (4, 8, 12, & 16) are written in the positive direction to both break response sets as well as measure presence or absence of positive affect.
How do you score CES-D 10?
CES-D 20 and CES-D 10 A score is assigned by totaling all items (after reversing the positive mood items]. The possible range for the 20-item scale is 0 to 60, and a cut off score of 16 or higher indicates the presence of significant depressive symptoms.
Is the CES-D a Likert scale?
The CES–D consists of 20 items in a self-report format measuring depressive symptoms experienced in the past week on a 4-point Likert scale ranging from 0 (rarely or none of the time) to 3 (most or all of the time).
Is CES-D free?
The CES-D is a cost effective, reliable, and valid screening instrument used to quickly assess the behavioral, cognitive, and affective symptoms of depression. The CES-D can be used without permission and is free of charge.
What were the measures of reliability and validity of the CES-D measurement?
The 14-item CES-D scale had satisfactory internal consistency with a Cronbach’s coefficient alpha of 0.87. The average inter-item correlation for all items was 0.32, which was acceptable and suggested that the items measure the same construct well.
How many items are on the Geriatric Depression Scale?
The GDS was originally developed as a 30-item instrument. Since this version proved both time-consuming and difficult for some patients to complete, a 15-item version was developed. The shortened form (GDS-S) is comprised of 15 items chosen from the Geriatric Depression Scale-Long Form (GDS-L).
