Cancer Genetics Risk Assessment and Counseling (PDQ®): Genetics - Health Professional Information [NCI] - The Option of Genetic Testing

Table 1. Clinical Utility of Genetic/Genomic Testsa continued...

In addition, cognitive deficits in the person being counseled may significantly limit understanding of the genetic information provided and hinder the ability to give informed consent and may also require further psychological assessment. Emotional responses to cancer risk may also affect overall mood and functioning in other areas of life such as home, work, and personal health management, including cancer screening practices.[69] Education and genetic counseling sessions provide an ongoing opportunity for informal assessment of affective and cognitive aspects of the communication process. Since behavioral factors influence adherence to screening and surveillance recommendations, consideration of emotional barriers is important in helping a person choose prevention strategies and in discussing the potential utility of genetic testing.[70,71]

The discussion of issues such as history of depression, anxiety, and suicidal thoughts or tendencies requires sensitivity to the individual. The individual must be assured that the counseling process is a collaborative effort to minimize intrusiveness while maximizing benefits. Determining whether the individual is currently receiving treatment for major psychiatric illness is an important part of the counseling process. Consultation with a mental health professional familiar with psychological assessments may be useful to help the provider develop the strategies for these discussions. It also may be beneficial for the individual to be given standard psychological self-report instruments that assess levels of depression, anxiety, and other psychiatric difficulties that he or she may be experiencing. This step provides objective comparisons with already established normative data.[72,73]

In addition to the clinical assessment of psychological functioning, several instruments for cancer patients and people at increased risk of cancer have been utilized to assess psychological status. These include the Center for Epidemiological Studies-Depression scale,[74] the Profile of Mood States,[75] the Hospital Anxiety and Depression Scale,[76] and the Brief Symptom Inventory.[77] Research programs have included one or more of these instruments as a way of helping refine the selection of people at increased risk of adverse psychosocial consequences of genetic testing. Psychological assessments are an ongoing part of genetic counseling. Some individuals with symptoms of increased distress, extreme avoidance of affect, or other marked psychiatric symptoms may benefit from a discussion with, or evaluation by, a mental health professional. It may be suggested to some people (generally, a very small percentage of any population) that testing be postponed until greater emotional stability has been established.
