[6] Krueger primarily studies the comorbidity between personality disorders and anxiety, as well as twins, heritability, personality development, conduct disorder, and antisocial personality disorder. [7] Krueger received the American Psychological Association's Award for Distinguished Scientific Early Career Contributions to Psychology in 2005.
Post-traumatic stress disorder can also coexist with anxiety disorders, ... A review of twin studies suggested that PTSD is, in part, a heritable mental illness. As much as 40 percent of someone ...
One of the first of these twin studies measured 800 pairs of twins, studied numerous personality traits, and determined that identical twins are most similar in their general abilities. Personality similarities were found to be less related for self-concepts, goals, and interests. [49] Twin studies have also been important in the creation of ...
In 1979, Thomas J. Bouchard began to study twins who were separated at birth and reared in different families. He found that an identical twin reared away from his or her co-twin seems to have about an equal chance of being similar to the co-twin in terms of personality, interests, and attitudes as one who has been reared with his or her co ...
Bipolar disorder is a serious mental health condition affecting 2.8 percent of adults in the United States. It involves episodes of mania (extreme highs) and depression (intense lows).
The first major revision of the MMPI was the MMPI-2, which was standardized on a new national sample of adults in the United States and released in 1989. [8] The new standardization was based on 2,600 individuals from a more representative background than the MMPI. [ 24 ]
For example, genetic differences account for about 43% of variance in panic disorder and 28% in generalized anxiety disorder. [68] Longitudinal twin studies have shown the moderate stability of anxiety from childhood through to adulthood is mainly influenced by stability in genetic influence. [98] [99] When investigating how anxiety is passed ...
The families and twins studies have showed that personality traits are moderately heritable, and can predict various lifetime outcomes, including psychopathology. The identical twins have a heritability of 40%, [ 1 ] suggesting that the additive genetic effects are responsible for the variance of personality traits for a moderate portion.
