Clinical Assessment
|
Systematic evaluation and measurement of psychological, biological, and social factors in a person presenting with a possible psychological disorder.
|
|
|
Diagnosis
|
Process of determining whether a presenting problem meets the established criteria for a specific psychological disorder.
|
|
|
Reliability
|
Degree to which a measurement is consistent--for example, over time or among different raters.
|
|
|
Validity
|

Withdrawal Design
|
Removing a tx to note whether it has been effective. In single-case experimental designs, a behavior is measured (baseline), an independent variable is introduced (intervention), and then the intervention is withdrawn. Because the behavior continues to be measured throughout (repeated measurement), any effects of the intervention can be noted. Also called reversal deisgn.

|
|
|
Multiple Baseline Design
|
Single-case experimental design in which measures are taken on two or more behaviors or on single behavior in two or more situations. A particular intervention is introduced for each at different times. If behavior changes is coincident with each introduction, this is strong evidence the intervention caused the change.

|
|
|
Twin Study
|
In genetics research, the comparison of twins with unrelated or less closely related individuals. If twins, particularly monozygotic twins who share identical genotypes, share common characteristics such as disorder, even if they were reared in different environments, then strong evidence of genetic involvement in those characteristics exists.
