Family stories and the use of heuristics: women from suspected hereditary breast and ovarian cancer (HBOC) families

Making sense of genetic uncertainty: the role of religion and spirituality

This article argues that to the extent that religious and spiritual beliefs can help people cope with genetic uncertainty, a limited spiritual assessment may be appropriate in genetic counseling. The article opens by establishing why genetic information is inherently uncertain and why this uncertainty can be medically, morally, and spiritually problematic. This is followed by a review of the range of factors that can contribute to risk assessments, including a few heuristics commonly used in responses to uncertainty. The next two sections summarize recent research on the diverse roles of religious and spiritual beliefs in genetic decisions and challenges to conducting spiritual assessments in genetic counseling. Based on these findings, religious and spiritual beliefs are posited as serving essentially as a heuristic that some people will utilize in responding to their genetic risks. In the interests of helping such clients make informed decisions, a limited spiritual assessment is recommended and described. Some of the challenges and risks associated with this limited assessment are discussed. Since some religious and spiritual beliefs can conflict with the values of medicine, some decisions will remain problematic.

How risk is perceived, constructed and interpreted by clients in clinical genetics, and the effects on decision making: systematic review

As an individual's understanding of their genetic risk may influence risk management decisions, it is important to understand the ways in which risk is constructed and interpreted. We systematically reviewed the literature, undertaking a narrative synthesis of 59 studies presenting data on the ways in which individuals perceive, construct and interpret their risk, and the subsequent effects. While most studies assessed perceived risk quantitatively, the combined evidence suggests individuals find risk difficult to accurately quantify, with a tendency to overestimate. Rather than being a stand-alone concept, risk is something lived and experienced and the process of constructing risk is complex and influenced by many factors. While evidence of the effects of perceived risk is limited and inconsistent, there is some evidence to suggest high risk estimations may adversely affect health and lead to inappropriate uptake of medical surveillance and preventative measures by some individuals. A more focused approach to research is needed with greater exploration of the ways in which risk is constructed, along with the development of stronger theoretical models, to facilitate effective and patient-centered counseling strategies.

Peer-support in coping with medical uncertainty: discussion of oophorectomy and hormone replacement therapy on a web-based message board

The Facing Our Risk of Cancer Empowered (FORCE) website is devoted to women at risk for hereditary breast and ovarian cancers (HBOC). To understand the unique health concerns and emotional support needs of these women, we examined threads on the FORCE archived message boards with relevance to the broader HBOC community. We report on a thread discussing the controversial decision to use hormone replacement therapy (HRT) following prophylactic oophorectomy (PO). We used a qualitative research inductive process involving close reading, coding and identification of recurrent patterns, relationships and processes in the data. Twenty-nine women posted 177 messages over 7 months. Two main groups of women posted: (1) Women who were BRCA+, had completed PO, and were debating or adjusting their HRT options in terms of optimizing both quality and quantity of life. (2) Women who were BRCA+, were contemplating PO, but wanted to better understand the potential physical and psychological consequences of surgical menopause before deciding. Frustrated by physicians' lack of knowledge and contradictory media articles about the long-term consequences of HRT in BRCA+ women, they sought resources, emotional support and specific experiential knowledge from each other and generated a unique sense of community and a high level of trust.

Family communication regarding inherited high cholesterol: why and how do patients disclose genetic risk?

Inadequate family communication concerning hereditary lipid disorders by index patients (IPs) may prevent their biological relatives from seeking testing and treatment. This lack of disclosure places the relatives at increased risk for cardiovascular disease. The present study, undertaken in the Netherlands, explored the reasons for family disclosure, and how disclosure was approached. Semi-structured interviews with 20 purposely sampled IPs revealed that they generally alerted their first-degree relatives of the genetic risk because they felt morally obliged to do so or because they were advised to do so by a health professional. However, IPs rarely alerted their more distant relatives due to insufficient risk knowledge or fear of being perceived as interfering in their relative's affairs. Furthermore, many IPs stated that they would not seek to persuade a relative to undergo testing out of respect for their autonomy. However, the findings did suggest that less direct methods were used for persuasion. An example would be stressing the severity of the condition. Consequently, the self-reported disclosures were incomplete and unbalanced. Typically, IPs provided information regarding the threat of inherited high cholesterol without furnishing information on means of coping with the risk. As IPs want and need professional support to help them disclose this information to their relatives, we suggest additional research about the ethical, practical and economic possibilities for this support.

Information processing in the context of genetic risk: implications for genetic-risk communication

Communicating genetic-risk information is fraught with difficulties, and there are no universally accepted guidelines for clinical practice. In this paper, we suggest that information-processing models may offer some guidance for the communication of genetic risk. The paper reviews selected literature from health and social psychology, including defensive reactions to threatening health information, the Extended Parallel Process Model (EPPM) and Self Affirmation Theory. Ultimately, it presents the Heuristic-Systematic Model (HSM) of information processing as a useful perspective from which to view genetic-risk communication. Through our review of this literature, we identify some of the variables found to influence the systematic or heuristic processing of risk information and note their relevance to genetic counseling contexts. We suggest that systematic information processing is conducive to informed decision-making, as well as improved understanding of risk information. Clinical practice implications derived from our review of these literatures are noted.

Narrative accounts of hereditary risk: knowledge about family history, lay theories of disease, and "internal" and "external" causation

In this study, the authors sought to examine how risk information is articulated in relation to health problems that people identify as personally important and relevant. The respondents were receptive to health education messages, using different types of information in relation to its personal relevance and as a resource for managing and exercising control over perceived risk. People were not fatalistic about disease risk, as reported in previous research. Instead, they were responsive to complex public health messages and actively engaged in rationalizing their health risks, although this did not necessarily result in behavioral change. Consequently, a theoretical distinction exists between taking responsibility for evaluating complex public health messages and taking responsibility for behavioral change. The authors conclude that people's rationalizations about health risks often mirror the medical model of disease, suggesting that they are responsive to, and not fatalistic toward, such public health information.

A gift or a yoke? Women's and men's responses to genetic risk information from BRCA1 and BRCA2 testing

This qualitative study explored the impact of genetic risk information from BRCA1/2 testing on individuals' subjective understandings of self and self-identity. In-depth interviews were conducted with 39 participants (34 women and 5 men) who had received test results from BRCA1/2 testing. Themes emerging from qualitative data analysis revealed that participants linked their positive results to becoming more aware of their physical selves (embodied self), their selves in relation to family (familial-relational self) and their selves in relation to wider kinship or social groups (social self). Genetic information was generally viewed as enabling; it allowed participants to take measures (surveillance or prophylactic surgery) to confront the disease. However, for a small minority of women, knowledge about their genetic risk had a profound and limiting effect on their agency. Rather than giving them a sense of control, they saw little opportunity to fight the disease. For a few people, identification of a genetic mutation thrust them into an uncertain state, that is in a position of being neither ill nor completely well. In one case, BRCA information led to a disruption of social identity. Further work is needed to assess the impact of age and life stage on psychological responses to genetic information on cancer susceptibility.

The Effect of Experiential Knowledge on Construction of Risk Perception in Hereditary Breast/Ovarian Cancer

The purpose of this study was to explore the connection between experiential knowledge of hereditary breast/ovarian cancer and understandings of personal cancer risk. Using a qualitative research design, the investigator conducted in-depth interviews with 53 individuals (45 female, 8 male) from families at high-risk for hereditary breast/ovarian cancer. Study results showed that two forms of experiential knowledge, empathetic and embodied knowledge, were integral to participants' constructions of their cancer risk. They also illustrated that knowledge derived from experience often took precedence over objective clinical estimates of risk. The paper discusses the clinical implications of these findings and suggests that counseling strategies, which expand upon patient's lived experience and knowledge of the disease, may enhance communication of genetic risk. Assessment of experiential knowledge promises to suggest new ways to frame genetic information that will enable people to better understand their objective risk or to modify exaggerated and/or inaccurate risk perceptions.
