Ambulatory blood pressure (ABP) may be an independent predictor of cardiovascular endpoints, but little is known about its psychosocial determinants. The acute effects of psychosocial processes on cardiovascular activity during daily life were examined by random-effects regression. Healthy adults (N = 120) were monitored over a 6-day period with ABP monitors and computer-assisted self-report assessments. Task strain, social conflict, and emotional activation were rated following each ABP measurement, as were activity, posture, and other covariates. Results show that blood pressure (BP) and heart rate (HR) were elevated during periods of emotional activation (high negative affect or high arousal). Diastolic BP was lower during periods involving high decisional control, and HR was lower during high-control, low-demand activities. There were substantial individual differences in the effects of psychosocial influences on ambulatory cardiovascular activity. Psychological factors are reliable determinants of ABP, which may account in part for the unique predictive value of ABP.
This study examines the relationships of mood, age, living with a spouse, and time elapsed since diagnosis of first recurrence to sexual interest. Seventy-two women with metastatic breast cancer and 26 of their spouses were recruited through their oncologists. Women and their spouses were administered a battery of measures designed to assess psychosocial and medical variables. Eighty-three percent of the women and 100% of the spouses indicated that sexual pleasure was something they wanted to experience; however, only 25% of the women indicating this interest and only 19% of the spouses reported that it had been easy for them to experience sexual pleasure. For patients, living with a spouse was significantly associated with being interested in experiencing sexual pleasure [p< .05]. Patients with lower mood disturbance were significantly more able to experience sexual pleasure than those with high mood disturbance scores [p < ,051. Ability to experience sexual pleasure was significantly and positively correlated between patients and their spouses (r=.56, p < .01). Sexuality is an important aspect of quality of life for metastatic breast cancer patients and their spouses. Further research is needed to examine psychosocial factors that affect sexuality for this population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
