Mood disturbance in patients with recurrent ventricular dysrhythmia before insertion of implantable cardioverter defibrillator.

OBJECTIVE: To examine the relationships among personal factors (demographic variables and trait optimism); situational factors (ejection fraction, functional status, history of sudden cardiac arrest); coping and appraisal processes; and mood disturbance in patients hospitalized for recurrent ventricular dysrhythmia before the insertion of an implantable cardioverter defibrillator (ICD). DESIGN: Descriptive and correlational. SETTING: Five community and tertiary care hospitals in the southeast and midwest. PATIENTS: Eighty-four men and 17 women (aged 24 through 79) scheduled to receive an initial implant of an ICD. VARIABLES AND MEASURES: Trait optimism measured by the Life Orientation Tool; coping measured by the Jalowiec Coping Scale; threat-and-challenge appraisal measured by the Meaning in Illness Questionnaire; functional status measured by the Heart Failure Functional Status Inventory; and total mood disturbance measured by the Profile of Mood States. RESULTS: Hierarchical regression analysis revealed that factors of age, sex, optimism, functional status, and history of sudden cardiac arrest accounted for 47% of the variance in the total mood disturbance score (F = 7.44, df = 11.68, p = 0.00) with female sex, and less trait optimism, higher threat appraisal, and more use of evasive coping behavior as significant predictors. CONCLUSIONS: These findings can be used to identify patients with recurrent ventricular dysrhythmia who are potentially at risk for mood disturbance in the acute care setting before ICD insertion. Nursing interventions to address these factors can be developed and tested. Longitudinal studies on the response to ICDs should include assessment of preinsertion affective state.

Anger expression and ambulatory blood pressure: a comparison of state and trait measures.

OBJECTIVES: The goals of this study were (1) to compare trait and state measures of anger expression, (2) to examine associations between situational variables and anger expression, and (3) to examine relationships between trait and state anger expression and ambulatory blood pressure. METHODS: One hundred college students completed state and trait versions,of the Spielberger (1) anger expression scale. State measures were completed in response to specific anger-provoking situations as they occurred over a 7-day period. Ambulatory blood pressure was recorded on one of these days. RESULTS: Moderate correlations were observed between trait and state anger expression. Significant associations were found between a number of situational variables and state anger expression scales. Neither trait nor state anger expressions scales were related to blood pressure levels. CONCLUSIONS: These results indicate that trait and state measures of anger expression are not equivalent and that situational factors play an important role in anger expression. Situational variability may be an important factor in determining the health consequences of anger expression.

Parenting enhancement among Egyptian mothers in a tertiary care setting.

This study tested the efficacy and effectiveness of systematically planned parenting enhancement program aimed toward breaking the cycle of high-risk mothers producing high-risk babies in Egypt. The assumption is that self-esteem and self-care are requisites to effective parenting, which can be enhanced or impeded by human and environmental forces. Given that parenting is a learned behavior, it can be repatterned by modifying human-environmental processes.

Differences in maternal perception of the newborn among adolescents.

PURPOSE: To test the feasibility and efficacy of a Parenting Enhancement Program (PEP) on adolescent mothers' perceptions of the neonate and to ascertain the extent to which PEP reinforces the effects of maternal age or self-esteem on their perceptions. METHODOLOGY: Ninety-two pregnant adolescents were placed into one of two groups; one group participated in a PEP and the other group did not. A Background Information Questionnaire, Self-Esteem Scale (SES), and Neonatal Perception Inventory (NPI) were used to collect data from all the subjects at five intervals beginning during pregnancy and ending at 3 months postpartum. RESULTS: A t-test revealed significant differences between the two groups at 1 month postpartum on the NPI. The PEP group had a significant gain on the NPI from the second day postpartum to 1 month postpartum. The PEP subjects showed a significant gain on the SES over time. A significant relationship was found between SES and NPI at 1 month postpartum. CONCLUSIONS: The findings lend support for the use of the PEP. Self-esteem served to reinforce the effects of the PEP, but age did not make a difference.

Health care workers' role conceptions and orientation to family-centered child care.

This study, designed as a correlation survey, was predicated on the existence of belief systems and on the premise that health care workers' orientation to family-centered care can reflect the openness or closedness of their belief systems. It was hypothesized that health care workers' orientation to family-centered child care is directly related to their professional role conception and inversely related to their employee role conception. The two hypotheses were tested on a sample of nursing and medical personnel associated with restorative and preventive care of children in inpatient and outpatient settings in New York City, central Pennsylvania, and the Philippines. Three sets of Likert-type scales were used for data collection from 1974 through 1976. Data were analyzed by correlation technique and the F test. Findings supported the hypotheses, and some demographic factors were found to be reliable predictors of health workers' orientation to family-centered child care and their conception of the professional or employee role. Implications of the findings for nursing practice and education, as well as recommendations for future research, are discussed.
