Time frames for reassessment
Time frames for retesting vary considerably depending on factors such as diagnostic status, longitudinal course, treatment parameters, and recent/current life circumstances.
While empirical data is lacking regarding this matter, based on clinical experience, reevaluation in 18 to 24 months is generally appropriate for patients with neuropsychiatric conditions who are likely to gradually improve or slowly worsen over this time. Still, reexamination can be sooner (within 12 to 18 months) for patients who have experienced a more rapid and steep negative change in clinical status than initially anticipated.
For most patients with major mental illness, reexamination in 3 to 5 years is probably a reasonable time interval, barring a poorly understood and clinically significant negative change in functioning that warrants a shorter time frame. This suggested time frame would allow for sufficient time to better gauge improvement, stability, or deterioration in functioning and whether the reason(s) for referral have evolved. On the other hand, this time interval is somewhat arbitrary given the lack of empirical data. Therefore, on a case-by-case basis, it would be helpful for psychiatrists to consult with their patients and preferably with the psychologist who completed the baseline evaluation to determine a reasonable interval between assessments.
For patients who have undergone long-term/intensive treatment, reassessment in 3 or 6 months to as long as 1 year after the patient completes the program should be considered. Patients who undergo medical interventions such as neurosurgery or ECT—which can be associated with short-term, at least partially reversible negative effects on mental status—reassessment usually is most helpful when initiated as one or more screening level examinations for several weeks, followed by a comprehensive psychometric reassessment at the 3- to 6-month mark.
Suggestions for future research
Additional research is needed to ascertain the attitudes and opinions of psychiatrists and other physicians who use psychometric test data regarding how psychologists can most effectively communicate a recommendation for reassessment in their reports and clarify the ways psychiatrists can productively address this issue with their patients. Survey research of this kind should include questions about the frequency with which psychiatrists formally refer patients for retesting, and estimates of the rate of follow-through.
