What does the concordance rate measure?
Concordance Rate is a term that is used in statistics and by geneticists to describe the rate of probability that two people with shared genes will develop the same organic disease. These conditions may or may not occur despite a genetic predisposition.
Why is concordance rate important in psychology?
Most, if not all, mental illnesses are caused by an interaction of genes and environment. Since genes and environment both matter, the question is no longer ‘nature or nurture?’ Concordance rate is a statistical index that researchers use to determine the relative influence of nature and nurture.
What is example of concordance?

What does concordance mean in criminology?

What does a concordance rate indicate quizlet?
A concordance rate indicates. the percentage of twin pairs or other pairs of relatives who exhibit the same disorder.
What is a concordance study?
In genotyping studies where DNA is directly assayed for positions of variance (see SNP), concordance is a measure of the percentage of SNPs that are measured as identical.
What does high concordance rate mean?
Concordance, as used in genetics, usually means the presence of the same trait in both members of a pair of twins. Discordant rates that are higher than concordant rates express the influence of the environment on twin traits.
What is a good concordance rate?
Such methods constitute what is called concordance analysis….Table 1.
| Value of κk | Quality of agreement |
|---|---|
| 0.21–0.40 | Fair |
| 0.41–0.60 | Moderate |
| 0.61–0.80 | Good |
| 0.81–1.0 | Very good |
What is the purpose of a concordance?

The amount of similarity in phenotype between a set of individuals. May be used to refer to the presence of the same trait in both members of a pair of twins.
What is the concordance rate for schizophrenia in monozygotic twins?
[2] Analyzing classic studies of the genetics of schizophrenia done as early as in 1930s, Fischer concludes that a concordance rate for psychosis of about 50% in monozygotic twins seems to be a realistic estimate, which is significantly higher than that in dizygotic twins of about 10–19%.
Which is the best definition of concordance rate?
Psychology Definition of CONCORDANCE RATE: the amount of twin pairs or other genetically related persons who show a certain feature or illness.
Which is the best definition of concordance in genetics?
The strict definition is the probability that a pair will both have a certain characteristic given that one of the pair has the characteristic. A twin study examines the concordance rates of identical twins having the same trait, especially a disease, which can help determine how much the disease is affected by genetics versus…
How to calculate the pairwise concordance rate for twins?
The formula for the pairwise concordance rate is this: First, we will calculate the pairwise concordance rate for identical twins. We plug into the equation the number of concordant identical twin pairs (50) and the number of discordant identical twin pairs (50). (Note that C I is used to indicate it is the rate for identical twins.)
What is the concordance rate for bipolar disorder?
For example, a widely reported study conducted in Denmark found that the concordance rate of identical twins for bipolar disorder was 68% while the concordance rate for fraternal twins was only 8%.
