This study sought to examine the psychophysiological correlates of forgiveness in response to interpersonal conflict. One hundred eight college students (44 males and 64 females) participated in two interviews about times of interpersonal betrayal, one about a parent and one about a friend/partner. Measures of forgiving personality and state forgiveness were collected, as well as stress, hostility, empathy, and self-reported illness symptoms. During baseline, interviews and recovery periods, repeated measures were taken of blood pressure, heart rate, frontalis EMG, and skin conductance. Trait forgiveness was associated with lower levels of blood pressure. State forgiveness was associated with lower blood pressure levels, heart rate, and rate pressure product. Acute, stress-induced reactivity was also linked to forgiveness: state forgiveness was associated with diastolic and mean arterial pressure and rate pressure product reactivity during the parent interview. Increased blood pressure recovery after stress was also linked to trait forgiveness. Forgiveness may produce beneficial effects directly by reducing allostatic load associated with betrayal and conflict, and indirectly through reductions in perceived stress.

The relationship of forgiveness, both state and trait, to health was assessed. Eighty-one community adults completed a packet of questionnaires and participated in a laboratory interview about a time of hurt or betrayal. Heart rate and blood pressure were recorded during a 10 min baseline, the interview and during a recovery period; interviews were structured around a framework of questions and videotaped. Four measures of forgiveness were all statistically associated with five measures of health (physical symptoms, medications used, sleep quality, fatigue, and somatic complaints). Trait forgiveness was associated with decreased reactivity (rate-pressure product) to the interview, but sympathetic reactivity did not account for the trait forgiveness–health association. Four mechanisms or pathways by which forgiveness could lead to fewer physical symptoms were examined: spirituality, social skills, reduction in negative affect, and reduction in stress. All factors either partially or fully mediated the effect of forgiveness on health; however, the strongest mediator for both state and trait forgiveness was reduction in negative affect. For state forgiveness, the second strongest mediator was reduction in stress; for trait forgiveness, both conflict management and reduction in stress were strong contributors.

Due to the importance of baseline and recovery levels in the computation of reactivity, two studies were conducted to determine an alternative method to traditional rest for achieving baseline and recovery levels of cardiovascular measurements. Watching a relaxing, aquatic video was compared with a traditional resting baseline to determine the better method for achieving low baseline levels. In addition, watching the video was compared with traditional rest during 5-min post-task recovery periods. Systolic (SBP) and diastolic blood pressure (DBP) decreased more during the baseline period when subjects viewed the video than when subjects rested quietly. Similarly, subjects displayed greater recovery following the mental tasks when they watched a video than when they merely sat quietly. It is recommended that researchers standardize baseline procedures by showing a relaxing video before administering tasks for the assessment of cardiovascular reactivity.

Many conceptualizations of forgiveness currently exist in the forgiveness literature. The present study adds another perspective to the forgiveness discussion by investigating lay definitions of forgiveness, as well as reasons for forgiveness and nonforgiveness. In Study 1, undergraduate students completed a questionnaire packet in which they provided three narratives of interpersonal offense: a time when they had been hurt and then forgave the offender, a time when they had been hurt and did not forgive, and a time when they had hurt someone else and were forgiven. Respondents were also asked questions about their conceptualization of forgiveness and the factors that influence their decisions to forgive or not forgive. In Study 2, community adults participated in interviews during which they described a time when they had been betrayed or hurt. Following their story, participants answered questions about their definitions of and motivations for forgiveness. A number of important themes in forgiveness definition and motivation are identified, and important similarities and differences between the under-graduate and community samples are discussed. In particular, it is noted that primary motivations for forgiveness appear to be largely self-focused, rather than altruistic.

The primary focus of this study was to investigate the roles of spirituality and religiosity in self-reported physical health, and to determine whether there is an association between an individual’s spirituality and cardiovascular responses to two stressors. Fifty-two females participated in both a betrayal interview and a structured interview, during which blood pressure and heart rate were monitored. Spirituality, as assessed by the Spiritual Well-being Scale, was associated with perceived stress, subjective well-being, and medication use. The Existential Well-being subscale predicted fewer physical health symptoms and was associated with lower mean heart rate and decreased heart rate reactivity. The Religious Well-being subscale was associated with reduced systolic blood pressure reactivity in response to the structured interview. These findings suggest that spirituality may have a salutary effect on health, even in a fairly young sample. While previous studies have predominantly reported that religion, as well as spirituality, have a health protective effect, this study did not find strong support for that conclusion. Religiosity in this age group may still be undergoing developmental maturity, which may explain the lack of relationships to health.

The debate over altruistic and egoistic motivations for helping has a long history and evidence supports both motives. Immediate and sustained helping following the September 11 attacks on the United States were examined. The three most commonly reported helping behaviors were donating money, praying, and donating blood. Six reported motivations for giving emerged: to relieve one’s own distress, to relieve the other’s distress, to show patriotism, to show civic responsibility, the desire for support in a similar situation, and knowing someone involved. Less giving was reported after 1 year than immediately following the event. The only motivation related to sustained giving was giving to relieve the other’s distress. Results are discussed using two theories of helping.

The present study delineates a method for the quantification of six hemodynamic reactivity patterns, in response to a laboratory stressor, and examines the psychophysiological correlates of individual differences in these patterns. One hundred and ninety-four young adult men and women participated in rest periods and two laboratory stressors, mental arithmetic and an anger recall interview. Measures were taken of blood pressure, heart rate, and cardiac output, from which total peripheral resistance was derived, as well as state reports of feelings during the tasks. Six hemodynamic reactor patterns were identified: Non-reactors, Mild Myocardials, Mild Vasculars, Myocardials, Vasculars, and Dual Reactors, each associated with a unique profile of cardiac output and total peripheral resistance change. Myocardial reactors to the interview had the highest resting levels of blood pressure and total peripheral resistance. Dual reactors had the largest increases in diastolic reactivity; Dual and Myocardial reactors had the largest increases in systolic reactivity. The extreme reactor groups (Dual, Myocardial, Vascular) all reported greater task invigoration than the Non-reactors, who reported greater efforts to relax. Reactor groups were similar on anger-related trait affect. Based on both resting blood pressure and magnitude of task-induced reactivity, Myocardial and Dual reactors may be at the greatest risk for subsequent hypertension.

ABSTRACT In order to explore the association between hostility and womens health, this study examined the relationship of hostility to cardiovascular reactivity during stressful, interpersonal confrontations. Prior to the task, each participants level of hostility, methods of coping with stress, and perceived social support were evaluated. Blood pressure and heart rate were monitored in ninety females during two discussions with a disagreeing confederate. In one discussion, participants were given positive feedback concerning their performance, while in a second discussion, participants were given non-positive feedback concerning their effectiveness in expressing their viewpoint. The results indicate that low hostile women displayed greater systolic blood pressure and heart rate increases than high hostile women during the discussions. In addition, participants exhibited greater systolic blood pressure and diastolic blood pressure reactivity during the positive feedback condition than during the non-positive feedback condition. However, for diastolic blood pressure, these results were qualified by an interaction, such that low hostile women displayed greater reactivity during the positive feedback condition than during the non-positive feedback condition, while high hostile women were equally reactive in both feedback conditions. State assessment of coping styles indicated that high hostile women may be less reactive due to withdrawal and lack of engagement during the task, while low hostile women may show greater engagement, especially when encouraged by positive feedback.
