Bereavement coping self-efficacy in cancer widows.

This study applied social cognitive theory to help explain the differential outcomes observed in conjugal bereavement. Specifically, a measure of bereavement coping self-efficacy was created and relationships tested with psychological, spiritual, and physical health outcomes. One hundred and one women whose husbands had died from cancer within the last year served as participants. Mean age of this relatively well-educated, predominately Caucasian sample was 54 years old. Median time since death was between 6 months and a year. Results supported the hypotheses that bereavement coping self-efficacy was a significant predictor of emotional distress, psychological well-being, spiritual well-being, and physical health perceptions after controlling for several other important factors. Theoretical and clinical ramifications of these findings are discussed.

Psychometric properties of a hurricane coping self-efficacy measure.

This brief report describes the psychometric properties of an instrument designed to measure Hurricane Coping Self-Efficacy (HCSE). Survivors of Hurricane Andrew (n = 165) and Hurricane Opal (n = 63) completed the HCSE and assessments of optimism, social support, distress, and resource loss. Principal components factor analyses revealed a unidimensional structure for the HCSE. Internal consistency of the HCSE was strong. In both samples, HCSE was positively associated with optimism and social support, but negatively associated with general psychological distress, trauma related distress, and resource loss. Finally, hierarchical regression analyses demonstrated that the HCSE explained a significant amount of experimental variance for intrusive thoughts and avoidance after controlling for social support, lost resources, and optimism.

Coping self-efficacy buffers psychological and physiological disturbances in HIV-infected men following a natural disaster.

The importance of coping self-efficacy (CSE) appraisals on psychological and physiological functioning for HIV seropositive patients facing a severe environmental stressor was tested comparing 37 HIV-infected gay men and 42 healthy male control participants following Hurricane Andrew. Results suggested that greater levels of CSE were related to lower emotional distress and posttraumatic stress disorder (PTSD) symptoms in both groups. In addition, greater CSE was associated with lower norepinephrine to cortisol ratios in the HIV group but not in the healthy control group. Results are discussed in relation to the coping process for HIV-infected individuals specifically and chronically ill populations in general who face severe environmental stressors.

Psychological stress and myocardial perfusion in coronary disease patients and healthy controls.

This study examined the effect of two different psychological stressors on regional cardiac perfusion in six men with coronary heart disease (CHD) and nine healthy controls. Subjects recalled an anger experience and an anger plus helpless (i.e., Desperation Recall Task) experience during positron emission tomography (PET). Emotional reactivity, blood pressure, and heart rate were also assessed. Experimental manipulations generated significant emotional and cardiovascular reactivity. Cardiac perfusion to diseased myocardial segments failed to show any significant differences between CHD patients' diseased segments and controls' healthy segments for the Anger Recall task or the Desperation Recall Task. Results failed to confirm previous findings of coronary artery constriction while reliving an angry experience, yet are consistent with other studies utilizing mental arithmetic. Vasoactive medication use, sample size, and perfusion variability may have contributed to these findings.
