Epidemiologic Depression Symptomatology
Radloff, L. S. · 1977
別名: CES-D framework · Depressive Symptomatology
This framework measures current depressive symptomatology in the general population rather than in clinical samples, which shapes every design decision behind it. Items emphasise affective and interpersonal experience over the vegetative and somatic symptoms that dominate clinical instruments, because in community samples somatic items pick up physical illness. The reference window is the past week, making it a state measure. Positively worded items are included specifically to break response set. The output is a symptom-burden score for population description, not a case identification.
Framework for measuring current depressive symptomatology in the general population, developed at the NIMH Center for Epidemiologic Studies (Radloff, 1977). Depression is operationalized as the frequency of symptoms over a single week — emphasizing the affective component (depressed mood) — rather than as a clinical diagnosis: items were selected from previously validated scales to cover the major symptom components, including the deliberate measurement of positive affect, whose absence is part of depression that pure symptom lists miss. The measured state is expected to move with life events; scores are read against published screening cutoffs, never as diagnostic categories.

歴史的背景
Radloff developed the Center for Epidemiologic Studies Depression Scale at the U.S. National Institute of Mental Health in 1977, assembling items from existing clinical scales but selecting for population rather than clinical use. It became the standard instrument in large epidemiological cohorts and ageing studies, with 20-item and 10-item forms. Eaton and colleagues published a revised version in 2004 aligning items with modern DSM criteria. Its longevity means decades of comparable population data exist, which is why cohorts continue to use it despite newer alternatives.
構成概念
抑うつ症状
Current depressive symptomatology as frequency of symptoms over the past week (Radloff, 1977): depressed mood, feelings of guilt and worthlessness, helplessness and hopelessness, psychomotor retardation, loss of appetite, and sleep disturbance, with the deliberate inclusion of positive affect whose absence is part of depression that pure symptom lists miss. A state expected to move with life events, read against published screening cutoffs — never a diagnosis.
抑うつ気分
The first of Radloff's four CES-D factors (1977, p. 397): the core dysphoric mood — feeling sad, depressed, lonely, fearful, and unable to shake off the blues. Descriptive grouping for report prose; not a scored scale.
ポジティブ感情
The second of Radloff's four CES-D factors (1977, p. 397): the presence or absence of positive feeling — feeling as good as other people, hopeful, happy, enjoying life. Measured through reverse-keyed items so that rarely feeling happy raises the score the same way often feeling sad does. Descriptive grouping for report prose; not a scored scale.
身体症状と活動低下
The third of Radloff's four CES-D factors (1977, p. 397): the bodily and psychomotor side of depression — being bothered by things, poor appetite, effort in everything, restless sleep, trouble concentrating, inability to get going. Descriptive grouping for report prose; not a scored scale.
対人関係の困難
The fourth of Radloff's four CES-D factors (1977, p. 397): the social perception component — feeling that people were unfriendly or disliked you. Descriptive grouping for report prose; not a scored scale.

この理論に基づくテスト
実践的応用
The scale is the workhorse of population mental-health surveillance, used to estimate symptom prevalence, track trends over time, and compare subgroups in large cohort studies of ageing, employment and social determinants. In research it serves as a continuous outcome in intervention trials where a clinical diagnosis would be too coarse. For individuals, its one-week window makes it a snapshot of a recent period — useful for noticing change, meaningless as a label.
測定方法
Self-report symptom-frequency items over the past week, summed with reverse-scored positive items; interpreted as a continuous symptom-burden score against population norms rather than as case identification.
批評と制限事項
The conventional cutoff of 16 has poor specificity against diagnostic interviews, over-identifying cases by a wide margin, and the instrument was never designed to do case-finding despite being routinely used that way. The four-factor structure — depressed affect, positive affect, somatic, interpersonal — is unstable across cultures, and the reverse-worded positive-affect items in particular function differently across language groups, complicating cross-national comparison. Somatic items still inflate scores among older and medically ill respondents, the very populations where the scale is most used.
