Overconfidence in Managing Health Concerns: The Dunning-Kruger Effect and Health Literacy.

Health literacy is often low within the general population. The Dunning-Kruger effect (DKE) suggests that individuals may experience a cognitive bias in which they overestimate their own knowledge base. This study examines the DKE regarding health literacy and health behaviors. A community sample (n = 504) completed questionnaires measuring objective health literacy, confidence in health knowledge, and health behaviors and medical conditions. Results support the presence of a DKE for health literacy; individuals with low health literacy reported equal or greater confidence in health knowledge than individuals with higher health literacy. Individuals with lower health literacy reported more problematic engagement in health behaviors. Low health literacy can impact engagement in health behavior and effect health outcomes, but individuals may not realize this deficit. Implications for clinical intervention include the need to address cognitive bias and enhance motivation to participate in health literacy interventions.

Physical and psychological abuse in breast cancer survivors and cancer-free women.

The purpose of this study was to provide a preliminary examination of intimate partner abuse in survivors of breast cancer relative to women who have never been diagnosed with cancer. The current study retrospectively evaluated the presence of physical or severe psychological abuse before cancer diagnosis, during treatment, and after remission of cancer in a sample of 206 ethnically diverse breast cancer survivors and 206 age- and ethnicity-matched control participants. Breast cancer survivors were less likely than controls to report abuse and did not report significant changes in frequency of abuse after cancer diagnosis or treatment.

Applying the transtheoretical model to female and male perpetrators of intimate partner violence: gender differences in stages and processes of change.

The Transtheoretical Model has been recently applied to men seeking services at battering intervention and prevention programs (Eckhardt, Babcock, & Homack, 2004; Murphy & Baxter, 1997). This study considers whether women arrested for intimate partner violence differ from male perpetrators in terms of stages of change and processes of change. No gender differences were found regarding stage of change. In general, all individuals presenting for treatment were in the early stages of change. The use of various processes of change was strongly related to stage of change, with individuals in the more advanced stages of change using more behavioral and experiential strategies to become nonviolent. However, except for the use of social liberation strategies, there were no gender differences in the use of the various processes. These findings suggest that the Transtheoretical Model may apply to female perpetrators equally as well as to male perpetrators. Intervention programs designed for male batterers using the Transtheoretical Model may also be helpful in the treatment of women arrested for domestic violence.

Management of terminal illness: a medical school-hospice partnership model to teach medical students about end-of-life care.

Physicians are not only called upon to deal with biological, but also with psychosocial issues and concerns in the treatment of the terminally ill. Their training, however, usually does not prepare them to value palliative care, or help them cope with personal feelings about death and possible grief over a patient's loss. The authors describe what one medical school is doing regarding the challenge of preparing medical students to deal more competently and confidently with end-of-life scenarios they will encounter as primary care practitioners in underserved areas of a rural state.
