Inclusion of Specific Environmental and Endophenotypic Variables in Behavior Genetic Models Standard behavior genetic analyses represent genetic and environmental influences as unspecif ied, anonymous, or ‘‘black box’’ variables. Kendler notes that the statistical power to detect shared environmental influences is low in such standard models, whereas incorporating specified environmental variables within a behavior genetic model […]

Rende, Plomin, Reiss, & Hetherington found shared environmental influences for extreme depression scores in adolescents (c2 = .44) and no significant genetic influence on extreme scores.

Reliability and Validity of Clinical Diagnosis As indicated, clinical diagnosis usually results in a specific categorization or label. After the patient has been appraised, the clinician offers a diagnosis (e.g., schizophrenia, paranoid type).

interpersonal diagnosis of personality

McLemore and Benjamin proposed an interpersonal behavior taxonomy, based on their contention that useful aspects of psychiatric diagnostic schemata are psychosocial and that most diagnoses of ‘‘functional mental disorders’’ are made on the basis of observed interpersonal behavior.
