Intelligence test scores can be complex, however, involving a variety of cognitive abilities, the influence of cultural factors, varying performance under differ- ent conditions, and issues related to the nature of intelligence. Psychological testing: Principles, applications, and is- sues 5th ed. When psychiatrists are acting in the role of physician, they and the psychologist may have different conceptual models for describing a patient's disorder. Correlations determined by tests given with a wide interval, such as two months or more, provide a measure of both the relation between forms and the degree of temporal stability. This is especially important in cases where urgent clinical decisions danger to self or others may need to occur.
It is strictly a referral service. The instructions they received and the extent of agreement between judges should also be provided. This can be further reinforced if clinicians make early judgments and then work to confirm these judgments through seeking supporting in- formation. As a result, extensive research over the past 10 to 15 years has been directed toward developing a greater understanding of how the older and more traditional tests relate to different types and levels of cerebral dysfunction. Such a consideration potentially provides a rough estimate of how frequently the be- havior will occur in a given population or context. Incremental validity, then, refers to the ability of tests to produce information above what is already known. This method is usually adequate for most tests.

Behavioral assessment might be either an end in itself, or an adjunct to testing. Clapp University of Wyoming Katherine S. Thus, when the test is being used in actual practice, the examiner can be relatively confident that differences in scores are the result of an actual change in the trait being measured rather than random fluctuation. Recommendations should be realistic and practical.
A pri- mary limitation of assessment lies in the incorrect handling of the data, which is not integrated in the context of other sources of information behavioral observations, his- tory, other test scores. Throughout these phases, the clinician should integrate data and serve as an expert on human be- havior rather than merely an interpreter of test scores. The following section outlines the most important of these guidelines along with additional related issues. Although the steps in assessment are isolated for conceptual convenience, in actuality, they often occur simultaneously and interact with one another. Ackerman The University of Texas at Dallas Jaime L. Furthermore, much new research in such areas as neuropsychology, cognitive science, and psychopathology have made major impacts on how many tests and other assessment procedures are used and interpreted.

All of these may affect the relevance of, and approach to, testing, but these issues may not be ap- parent if the initial referral question is taken at face value. A variation is to have two different examiners test the same client using the same test and 16 Introduction then to determine how close their scores or ratings of the person are. Computer Code Because altering computer code in any way e. Another hypothetical test that, based on its item content, might seem to mea- sure what is described as musical aptitude may in reality be highly correlated with ver- bal abilities. This understanding includes appreciating the issues, concerns, terminology, and likely roles of the persons from these contexts.
One basic distinction is between merely managing the person versus attempting a program of rehabilitation. This may include a history of previous attempts at treatment and a summary of the relationship among the parents, school, courts, and child. Thus, issues such as countertransference and possibly the therapist's unreasonable expectations may be equally or even more important than looking at a patient's characteristics. The degree of corre- lation between the two scores indicates the extent to which the test scores can be gen- eralized from one situation to the next. The client's responses also need to be interpreted by the clinician.
Brent Donnellan Michigan State University Nicholas R. Only recently has the value of the services they have been performing for decades and the need to make them available through formal programs been recognized. Related to insanity is whether the defendant is competent to stand trial. Furthermore, the child's values, motiva- tion, and sense of personal efficacy need to be taken into consideration, along with possible biomedical difficulties. This obser- vation was found to be true unless the clinicians were very knowledgeable, in which case they were likely to have a moderate level of confidence Garb, 1989.
Finally, clinicians have to assess the extent to which they need training to administer and interpret the instrument. The earliest form of assessment was through clinical interview. Typically, any behavioral difficulty is closely linked with the child-teacher interaction. The clinician typically develops hypotheses based on a client's responses and combines his or her observations with his or her theoretical vmderstand- ing of the issue. To submit to the Editorial Office of Yossef S. Their conclusions were combined against criterion judges who used a lengthy checklist of personality descriptions.
A judge might use a psychol- ogist's report as one of a number of factors to help determine a sentence, a penal offi- cer might wish consultation to help determine the type of confinement or level of dangerousness, or a parole officer might need assistance to help plan a rehabilitation program. Thomas Colorado State University Paul F. Investigations supporting clinical assessment in mental health, medical, forensic, and personnel screening settings are welcome.

The report ties together all sources of in- formation, often combining complex interprofessional and interpersonal issues. Some- times it is difficult to keep up with the sheer number of publications. The brief report should give a clear, condensed summary of the procedure of the study and as full an account of the results as space permits.
This approach is sometimes referred to as synthetic validity because examiners must integrate or synthesize the criteria reported in the test manual with the variables they encounter in their clinical or organizational settings. These guidelines have largely evolved through careful considerations of what constitutes ideal practice. It offers a model designed to ensure that assessors provide ethical and competent services and make useful contributions to the lives of the individuals they assess. When the patient's current condition, current environment, and future prospects have been evaluated, the examiner can then recommend the next phase in the intervention process. Research reviews generally support the value of clinical training, but this is dependent on the domain being assessed. At some point, it might be decided that the item content overrepre- sents, underrepresents, or excludes specific areas, and alterations in the items might be made accordingly. The empha- sis in the second phase is on developing multiple inferences that should initially be ten- tative.
