Text: The CES - D 8 and 10 item versions were implemented with yes / no response options at follow - up , respectively in ELSA and HAPIEE . For HAPIEE , the CES - D 8 version was simulated by eliminating two items on interpersonal relations that formed the CES - D 10 . The CES - D 8 measured whether 8 symptoms on depressed affect , somatic and retarded activity and positive affect were experienced for ' much of the time during the past week ' ( Radloff , 1977;Steffick , 2000 ) . Affirmative and negative responses to the first 6 and last 2 items , respectively , each counted as 1 ; and were summed to derive a score ranging from 0 to 8 for participants with data on at least 6 of the 8 items , as scoring guidelines require complete data on at least 75 % of the CES - D scale ( Radloff , 1977 ) .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
