Responses to threat information.

Using the Common Sense Model to examine responses to health risk information, a laboratory study was conducted. Subjects were assigned randomly to one of four groups by manipulating information about high or normal blood glucose (BG) and a low or high threat message about the controllability of Type II diabetes. Subjects in the high BG groups reported more diabetes-related symptoms and stronger intentions to change certain behaviors. Subjects reading a high-threat message expressed stronger intentions to see a health professional than did those reading a low-threat message. The results suggest that perceptions of one's risk status and the degree of threat associated with an illness effects symptom perceptions and behavioral intentions.

Beliefs about aging and illness in a community sample.

Findings from recent studies have demonstrated age group differences in coping with illness. One explanation for these age group differences has received little attention: perceptions of illness may differ with age and these differences in perception may account for the observed differences in coping. The purpose of this study was to examine the effects of age on illness perceptions along dimensions that influence coping. Specifically, we explored perceptions about aging as a cause of illness and perceptions about the effect of age on seriousness, curability and controllability of illness. Four hundred fifty-one community-dwelling adults (age range 20 to 90 years) participated in the study. The pattern of results showed respondents of all ages expressing the belief that aging is associated with increased susceptibility to disease and lowered potential for control or cure. Implications of these beliefs for health monitoring and coping with illness are discussed.

Processes of self-care: monitoring sensations and symptoms.

One of the most basic processes in self-care has to do with how people monitor changes in their bodies, that is, how people identify and evaluate sensations and symptoms. This article reviews evidence from three research programs that have focused on the study of sensation/symptom processing using a shared conceptual framework, the Common Sense Model. The model is described first; a summary of findings from each series of studies is then provided. The article concludes with a discussion of the findings' contribution to knowledge of self-care, implications of the findings for nursing practice, and suggested directions for future research.

Aging: the lived experience.

This exploratory study examined the lived experience of aging in a group of 32 community dwelling adults aged fifty to eighty years (M = 68.4). Respondents completed in-depth interviews in which they described the meaning of aging, the "types of things" associated with aging in themselves and in others, and methods of coping with aging-related changes. Respondents' overall impressions of the meaning of aging were generally positive; however, the changes they associated with aging, both in themselves and in others, were almost uniformly negative. Five categories of coping activities were reported: compensation, stress management, maintenance, involvement with others, and alteration in meaning. In general, respondents reported high levels of satisfaction and effectiveness with respect to their coping activities. These findings suggest that individuals who believe they are coping successfully see aging as a positive period in their lives, despite the presence of a significant number of negative changes in themselves and in people close to them.

Long-lived lines of Caenorhabditis elegans can be used to establish predictive biomarkers of aging.

Long-lived recombinant inbred lines, some of which have mean and maximum life spans up to 70% longer than wild type, were used in these analyses. Longer life results from a slower exponential rate of increase in mortality. General motor activity decreases with chronological age in all genotypes; this decay in general motor activity is a biomarker of aging in that it is a predictor of maximum life span. The aging process has also been dissected into component processes. The length of development and the length of reproduction are unrelated to increased life span; lengthened life is due entirely to an increase in post-reproductive life span. Development, reproduction, and life span are each under independent genetic control. General motor activity and life span share at least one common rate-determining genetic component.

Psychological and spiritual well-being in college students.

Two separate correlational studies were conducted to investigate the relationship between spirituality and psychological mood states in response to life change. In the first study a spiritual well-being index, a spiritual-maturity scale, a life-change index, and a depression scale were administered to 95 freshman nursing students. The spiritual well-being index was composed of two sub-scales; a religious well-being and an existential well-being scale. In the second study a spiritual-outlook scale and the Profile of Mood State index was added to the above tests and administered to 75 randomly selected college students. The results demonstrated a weak positive relationship between life change and depression. unlike a previous study, spiritual well-being, existential well-being, and spiritual outlook showed strong inverse relationships with negative moods suggesting that spiritual variables may influence psychological well-being.

Impact of symptoms and aging attribution on emotions and coping.

Two experimental studies and a large field study were designed to examine how symptom severity, symptom duration, symptom ambiguity, and the association of symptoms with aging affected emotional responses and coping with illness threats. In Study 1, 280 respondents from the surrounding community reported the emotional and coping responses they would manifest to scenarios that varied the severity, duration, and ambiguity (i.e., labeled vs. unlabeled) of a common set of symptoms. Severity had more of an impact on coping strategies than did duration or illness label; severe symptoms elicited stronger emotional upset and a higher incidence of both self-care behaviors and seeking of medical care. Symptoms of longer duration also resulted in increased seeking of medical care. Responses of the 334 adults participating in Study 2 replicated and extended these findings: A closed-ended item asking participants whether the symptoms could be attributed to aging showed that attribution of symptoms to aging increased with age, was more frequent for mild symptoms, and was associated with reduced emotional response to symptoms and a tendency to delay seeking treatment. Participants in the field study (168 patients seeking medical care for a variety of symptoms) completed interviews tracing symptom processing and emotional and coping reactions. The results provided evidence for the external validity of the scenario studies, as the attribution of symptoms to aging was greater for older than younger patients and resulted in a significant tendency to delay seeking medical care. Results of these studies suggest that symptom experience and symptom interpretation must be considered in the study of coping responses to illness threats.

Health practices and illness cognition in young, middle aged, and elderly adults.

The present paper examines reported frequencies of 21 health practices, beliefs that these health practices can prevent six different illnesses, and beliefs about those illnesses in a community sample of 396 people: 173 young (20 to 39 years), 111 middle-aged (40 to 59 years), and 112 elderly adults (60 to 89 years). Elderly respondents report higher frequencies of health-promoting actions (e.g., regular medical check-ups, avoidance of salt, regular sleep, and eating a balanced diet) than younger respondents. Health practices aimed at reinterpreting stress and controlling emotions (e.g., avoiding emotional stress, staying mentally alert and active) also increased with age. Belief that these 21 practices prevent specific illnesses was consistent across the three age groups. Beliefs about the six illnesses were consistent across age with three exceptions: Elderly people considered themselves more vulnerable to disease, saw it as more serious for them, and were less likely to use chronic mild symptoms, like weakness and aches, as illness warnings.

Identifying the attentional demands perceived by elderly people.

The capacity to direct attention is an essential part of life. However, excessive demand for attention produces difficulty in managing everyday activities and stressful life events. This study identified attentional demands of elderly people. Thirty elderly adults were interviewed to ascertain their perceptions of demands on them in four theoretically derived domains. Physical environmental demands included the weather and living space. Informational demands included facing new situations because of a move or the loss of a spouse as well as vision and hearing difficulties. Behavioral demands mentioned were tasks such as exercising, cooking, being able to drive, dealing with finances, and a loss of stamina. Affective demands mentioned were loneliness and worries and sadness about health and the future. A content analysis of the interview data produced items for an instrument to be used during future interventions with elderly people aimed at decreasing the level of demands and restoring the attentional capacity necessary for functioning at an optimal level. This article also discusses the implications of assessing elderly patients.

Funding and socialization in the doctoral program at the University of Wisconsin-Madison.

This article describes the model of funding and socializing doctoral students that has been used by the School of Nursing at the University of Wisconsin-Madison. The goal of the Madison program is to educate persons who are capable of conducting research that will contribute to the scientific knowledge base of nursing. This goal is accomplished through immersing students in all aspects of the research process. Critical components of socialization are described. These include the mentor-student relationship, participation in a research group, and participation in informal discussions of faculty and students' research programs. The importance of establishing funding mechanisms and faculty work loads that support socialization is also emphasized.

Genital human papillomavirus infection: common but not trivial.

One of the most prevalent sexually transmitted diseases is genital human papillomavirus (HPV) infection. Because of its potentially serious consequences for women, HPV infection is receiving a significant amount of attention from researchers and clinicians. We summarize the research and clinical literature on HPV infection. The nature of the virus, the prevalence of HPV infection, and modes of transmission are discussed. Both the physiological and psychological consequences of the infection are explored. Perspectives on treatment are examined, and suggestions for psychoeducational interventions are offered.

Consequences of sexual decisions: the perceptions of rural adolescents.

The purpose of this study was to examine the content of adolescent thinking about the consequences of choosing abstinence, sexual intercourse with a condom, and unprotected intercourse. Consequences for the relationship and for each partner's thoughts and feelings were explored. Participants were 116 high school students living in a rural area of a midwestern state; their average age was 16 years. They completed a series of open-ended questions about possible outcomes to a scenario involving sexual decision making. Content analysis of responses revealed that about half of the participants associated abstinence with positive consequences; however, it was also associated with insecurity and the possibility of losing the relationship. Sexual intercourse with a condom was viewed as an indication of caring and responsibility and was associated with positive outcomes for the relationship. Identified consequences of unprotected intercourse were almost entirely negative. Some differences in perceived consequences were influenced by the gender of the partner. Integration of these findings into programs designed to prevent sexual risk-taking is discussed.
