Montgomery Asberg Depression Rating Scale (MADRS)

Purpose

The Montgomery Asberg Depression Rating Scale (MADRS) is used by clinicians to assess the severity of depression among patients with a diagnosis of depression. It is designed to be sensitive to change resulting from antidepressant therapy.

In-Depth Review

Purpose of the measure

The Montgomery Asberg DepressionIllness involving the body, mood, and thoughts, that affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. A depressive disorder is not the same as a passing blue mood or a sign of personal weakness or a condition that can be wished away. People with a depressive disease cannot merely "pull themselves together" and get better. Without treatment, symptoms can last for weeks, months, or years. Appropriate treatment, however, can help most people with depression.

Available versions

The MADRS was developed by Stuart Montgomery and Marie Asberg in 1979. It was developed from Asberg’s Comprehensive Psychopathological Rating Scale, which was designed to evaluate psychiatric treatment.

Features of the measure

Items:
The MADRS has 10 items that are completed during a clinical interview. The following items are included in the MADRS:

1. Apparent sadness
2. Reported sadness
3. Inner tension
4. Reduced sleep
5. Reduced appetite
6. Concentration difficulties
7. Lassitude
8. Inability to feel
9. Pessimistic thoughts
10. Suicidal thoughts

Originally the MADRS was published without suggested questions for clinicians to use in eliciting the information they need to rate the items. In 2008, Williams and Kobak developed the Structured Interview Guide for the MADRS (SIGMA) to provide structured questions that should be asked exactly as written to ensure standardisation of administration. Follow-up questions are also provided to clarify symptoms if required. Inter-rater reliabilityA method of measuring reliability . Inter-rater reliability determines the extent to which two or more raters obtain the same result when using the same instrument to measure a concept.
using Intraclass CorrelationThe extent to which two or more variables are associated with one another. A correlation can be positive (as one variable increases, the other also increases - for example height and weight typically represent a positive correlation) or negative (as one variable increases, the other decreases - for example as the cost of gasoline goes higher, the number of miles driven decreases. There are a wide variety of methods for measuring correlation including: intraclass correlation coefficients (ICC), the Pearson product-moment correlation coefficient, and the Spearman rank-order correlation.
Coefficient with the SIGMA was reported to be excellent (r = 0.93).

Scoring:
Each item has a severity scale from 0 to 6, with higher scores reflecting more severe symptoms. Ratings can be added to form an overall score (from 0 to 60). Snaith, Harrop, Newby, and Teale (1986) proposed the following cut-offs: scores of 0-6 indicate an absence of symptoms; 7-19 represent mild depressionIllness involving the body, mood, and thoughts, that affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. A depressive disorder is not the same as a passing blue mood or a sign of personal weakness or a condition that can be wished away. People with a depressive disease cannot merely "pull themselves together" and get better. Without treatment, symptoms can last for weeks, months, or years. Appropriate treatment, however, can help most people with depression.

.

Time:
Interviews take 20 to 60 minutes to complete.

Subscales:
The MADRS has 10 subtests (each item is therefore considered a subtest): 1. Apparent sadness; 2. Reported sadness; 3. Inner tension; 4. Reduced sleep; 5. Reduced appetite; 6. Concentration difficulties; 7. Lassitude; 8. Inability to feel; 9. Pessimistic thoughts; 10. Suicidal thoughts

Equipment:
Only the questionnaire and a pencil are required to complete the MADRS.

Training:
No formal training is required to complete the MADRS.

Alternative form of the Montgomery Asberg Depression Rating Scale

A self-report version of the MADRS, the MADRS-S, was developed by Svanborg and Asberg in 1994. The MADRS-S has 9-items which are based on feelings over the past 3 days. The items of the MADRS-S are as follows: Mood; Feelings of unease; Sleep; Appetite; Ability to concentrate; Initiative; Emotional involvement; Pessimism; Zest for life.

Client suitability

Can be used with:

The MADRS can be administered to clients with strokeAlso called a "brain attack" and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a "schemic stroke", or the formation of a blood clot in a vessel supplying blood to the brain..

• The MADRS can be used with clients with aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a person's ability to communicate. It is most often the result of stroke or head injury.
  An individual with aphasia may experience difficulty expressing themselves when speaking, difficulty understanding the speech of others, and difficulty reading and writing. Sadly, aphasia can mask a person's intelligence and ability to communicate feelings, thoughts and emotions. (The Aphasia Institute, Canada), however one study examining its use in patients with aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a person's ability to communicate. It is most often the result of stroke or head injury.
  An individual with aphasia may experience difficulty expressing themselves when speaking, difficulty understanding the speech of others, and difficulty reading and writing. Sadly, aphasia can mask a person's intelligence and ability to communicate feelings, thoughts and emotions. (The Aphasia Institute, Canada) found that the MADRS was more difficult to complete than the DSM-IV, especially for patients with global, mixed non-fluent, and Wernicke types of aphasias. The MADRS also became less valid when a proxy was required (Laska, Martensson, Kahan, von Arbin, & Murray, 2007).

Should not be used with:

The MADRS is intended for use with patients with a diagnosis of a depressive illness only.

• Although the MADRS can be used with clients with cognitive impairments, certain features of the MADRS could bias the scores of these patients in the direction of higher depressionIllness involving the body, mood, and thoughts, that affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things.

People with a depressive disease cannot merely "pull themselves together" and get better. Without treatment, symptoms can last for weeks, months, or years. Appropriate treatment, however, can help most people with depression.
  scores and therefore should be used with caution in individuals with cognitive impairments. This is due to the complex wording of some of the subtests (especially the subtests of Concentration difficulty; Inability to feel; Lassitude; and Inner tension) (Sadavoy, Smith, Conn, & Richards, 2004).

Measurement Properties
ReliabilityReliability can be defined in a variety of ways. It is generally understood to be the extent to which a measure is stable or consistent and produces similar results when administered repeatedly. A more technical definition of reliability is that it is the proportion of "true" variation in scores derived from a particular measure. The total variation in any given score may be thought of as consisting of true variation (the variation of interest) and error variation (which includes random error as well as systematic error). True variation is that variation which actually reflects differences in the construct under study, e.g., the actual severity of neurological impairment. Random error refers to "noise" in the scores due to chance factors, e.g., a loud noise distracts a patient thus affecting his performance, which, in turn, affects the score. Systematic error refers to bias that influences scores in a specific direction in a fairly consistent way, e.g., one neurologist in a group tends to rate all patients as being more disabled than do other neurologists in the group. There are many variations on the measurement of reliability including alternate-forms, internal consistency , inter-rater agreement , intra-rater agreement , and test-retest .	Internal consistencyA method of measuring reliability . Internal consistency reflects the extent to which items of a test measure various aspects of the same characteristic and nothing else.

Psychometric Properties

Overview

We conducted a literature search to identify all relevant publications on the psychometric properties of the MADRS in individuals with strokeAlso called a "brain attack" and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a "schemic stroke", or the formation of a blood clot in a vessel supplying blood to the brain.. We identified 4 studies.

Floor/Ceiling Effects

No studies were identified that examined the floor/ceiling effects of the MADRS in individuals with strokeAlso called a "brain attack" and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a "schemic stroke", or the formation of a blood clot in a vessel supplying blood to the brain..

Fantino and Moore (2009) examined the floor and ceiling effects of the 9-item self-administered version of the MADRS-S in 278 outpatients diagnosed with Major Depressive Disorder. All items had adequate ceiling effects (total score: 0.4%). Floor effects ranged from poor (appetite item, 21.6) to excellent (total score: 0.0%).

Test-retest:
No studies were identified that measured the test-retest reliabilityA way of estimating the reliability of a scale in which individuals are administered the same scale on two different occasions and then the two scores are assessed for consistency. This method of evaluating reliability is appropriate only if the phenomenon that the scale measures is known to be stable over the interval between assessments. If the phenomenon being measured fluctuates substantially over time, then the test-retest paradigm may significantly underestimate reliability. In using test-retest reliability, the investigator needs to take into account the possibility of practice effects, which can artificially inflate the estimate of reliability (National Multiple Sclerosis Society).

Inventory (BDI – Beck, Ward, & Mendelson, 1961) in 22 patients with strokeAlso called a "brain attack" and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a "schemic stroke", or the formation of a blood clot in a vessel supplying blood to the brain. and found an excellent correlationThe extent to which two or more variables are associated with one another. A correlation can be positive (as one variable increases, the other also increases - for example height and weight typically represent a positive correlation) or negative (as one variable increases, the other decreases - for example as the cost of gasoline goes higher, the number of miles driven decreases. There are a wide variety of methods for measuring correlation including: intraclass correlation coefficients (ICC), the Pearson product-moment correlation coefficient, and the Spearman rank-order correlation.

Construct:
Farner, Wagle, Flekkoy, Wyller, Fure, Stensrod, et al. (2009) examined the construct validityReflects the ability of an instrument to measure an abstract concept, or construct. For some attributes, no gold standard exists. In the absence of a gold standard , construct validation occurs, where theories about the attribute of interest are formed, and then the extent to which the measure under investigation provides results that are consistent with these theories are assessed.
of the MADRS using factor analysis in 163 individuals with strokeAlso called a "brain attack" and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a "schemic stroke", or the formation of a blood clot in a vessel supplying blood to the brain.. They identified 3 distinct factors: Anhedonia; Sadness; and Agitation. The factor Anhedonia was related to cognitive impairment, Sadness to neurological impairment due to the strokeAlso called a "brain attack" and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a "schemic stroke", or the formation of a blood clot in a vessel supplying blood to the brain., and Agitation related to somatic factors not directly related to the strokeAlso called a "brain attack" and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a "schemic stroke", or the formation of a blood clot in a vessel supplying blood to the brain..

SensitivitySensitivity refers to the probability that a diagnostic technique will detect a particular disease or condition when it does indeed exist in a patient (National Multiple Sclerosis Society). See also "Specificity."

A depressive disorder is not the same as a passing blue mood or a sign of personal weakness or a condition that can be wished away. People with a depressive disease cannot merely "pull themselves together" and get better. Without treatment, symptoms can last for weeks, months, or years. Appropriate treatment, however, can help most people with depression.

How to obtain the MADRS?

The structured interview version of the MADRS is available as an appendix in the following publication:

Williams, J. B. W., & Kobak, K. A. (2008). Development and reliabilityReliability can be defined in a variety of ways. It is generally understood to be the extent to which a measure is stable or consistent and produces similar results when administered repeatedly. A more technical definition of reliability is that it is the proportion of "true" variation in scores derived from a particular measure. The total variation in any given score may be thought of as consisting of true variation (the variation of interest) and error variation (which includes random error as well as systematic error). True variation is that variation which actually reflects differences in the construct under study, e.g., the actual severity of neurological impairment. Random error refers to "noise" in the scores due to chance factors, e.g., a loud noise distracts a patient thus affecting his performance, which, in turn, affects the score. Systematic error refers to bias that influences scores in a specific direction in a fairly consistent way, e.g., one neurologist in a group tends to rate all patients as being more disabled than do other neurologists in the group. There are many variations on the measurement of reliability including alternate-forms, internal consistency , inter-rater agreement , intra-rater agreement , and test-retest .
