Social intimacy: An important moderator of stressful life events

Two studies were conducted to explore the role of social intimacy in predicting the individual's response to stress. In the first study the experimenter reinforced the experimental subjects' verbalizations during an interview on a fixed schedule for the first 3 minutes, withdrawing reinforcement for the final 4 minutes. The control group received reinforcement on a fixed schedule for the total 7 minutes. Subjects scoring low on a measure of intimacy disclosed less personal material during the withdrawal period in the experimental condition than in the control condition in contrast to high scoring subjects who maintained their level of disclosure for both parts of the interview. In the second study, previously experienced life change events were assessed. Individuals lacking a current intimacy were found to be prone to higher levels of emotional disturbance especially when many previous negative or few positive life change events had occurred.     

Irrational beliefs and the impact of stressful life events

The Ellis (1962) rational emotive therapy model would predict that individuals characterized by high levels of irrational beliefs would evaluate the impact of personally experienced life events as more negative (or less positive) than would individuals chartacterized by low levels of irrational beliefs. A sample of 155 undergraduate females provided data on irrational beliefs and a life experiences survey which included event impact ratings. The results provided general support for the hypothesis of a relationship between beliefs and perceived impact of stressful life events.     

Negative affectivity and the reporting of stressful life events

Maddi, Bartone, and Puccetti (1987) and Schroeder and Costa (1984) reported inconsistent findings regarding the impact of negative affectivity (NA; i.e., neuroticism) contaminated life event items on observed life event-illness relationships. Here, unlike the previous studied, such contaminated items were nonjudgmentally identified. Among a sample of managers and professionals, it was found that NA-contaminated items correlated significantly with three measures of well-being (depression, life satisfaction, and physical symptoms) and that uncontaminated items were unassociated with the well-being indicators. Moreover, in two of three cases, the correlations between contaminated items and the well-being measures were significantly different from the correlations between uncontaminated items and the well-being indicators. Therefore, we concluded that prior life event-well-being findings are inflated considerably by the use of NA-contaminated events. Suggestions for future life events research that incorporate the NA construct are detailed.     

Poverty, stressful life events, and coping strategies

It was hypothesized that individuals of low socioeconomic status are exposed to a greater number of stressful events and therefore have a higher incidence of psychological disorders. However, the way they interpret, evaluate and cope with these stressful situations may either cause them to maintain, intensify or eliminate their overall stress. Past research indicates that the poorest individuals tend most frequently to falsely minimize or avoid stressful situations, which lowers the probability of resolving their problems. The objective of this study is to discover and compare the situations that have produced a high level of stress in subjects of three different socioeconomic groups over the last three months, as well as the strategies they used to cope, and their perceived effectiveness. The sample included 900 subjects of both sexes living in Mexico City. Among them, 346 were extremely poor, 260 were moderately poor and 312 were not poor. The results indicate that socioeconomic status is related to the frequency with which subjects report certain kinds of stressful situations. It was also found that non-poor subjects use problem-focused coping methods more than the other groups, while the poor use more emotionally-focused coping strategies, This article analyzes the strategies used by each group in each type of stressful situation reported.     

Recent stressful life events and young children's school adjustment

A group of 211 first-to fourth-grade children who had experienced one or more recent stressful life events were compared to a demographically matched sample of 211 children who had not experienced such events on measures of school adjustment problems and competencies. Stressful life events were found to be associated with the presence of more serious school adjustment problems and fewer competencies. Those associations were strongest for children who had experienced multiple recent stressful events. The importance of preventive interventions for this at-risk group was emphasized and future research steps in the area were considered.     

The incidence of stressful life events of elementary school-aged children

Certain events, commonly found in the life histories of children, have been characterized as potentially stressful (Rutter, 1981). There is some evidence to support the hypothesis that these events play a role in the etiology of various disorders, although the nature of that relationship is not clear (Dohrenwend & Dohrenwend, 1974). Yet that relationship remains the subject of considerable interest, as can be seen by the number of studies on the influence of stressful life events on children's emotional adjustment and school performance (Boike, Gesten, Cowen, Felner, & Francis, 1978; Felner, Ginter, Boike, & Cowen, 1981; Felner, Stolberg, & Cowen, 1975; Gesten, Scher, & Cowen, 1981; Felner, Stolberg, & Cowen, 1975; Gesten, Scher, & Cowen, 1978; Rolf & Garmezy, 1974; Sandler & Block, 1979; Siegel, 1981). Sandler and Ramsey (1980) have suggested that the role of life events as stressors can be understood to be a function of, among other things, the frequency of occurrence of events. For research and clinical assessment purposes, baseline data on the incidence of stressful life events of children seem to be necessary. In order to collect and organize baseline data, the relevant demographic variables must be identified. It was hypothesized that there might be two relevant demographic variables: age and socioeconomic status (SES). The purposes of this study were to (a) conduct a survey to gather baseline data on the incidence of stressful life events of children, and (b) examine the effects of age and SES on the number of events reported.     

A prospective study of stressful life events and schizophrenic relapse

In this prospective, longitudinal study, 11 recent-onset schizophrenic outpatients who met criteria for psychotic relapse or significant psychotic exacerbation during a 1-year period of standardized maintenance medication, and 19 patients who did not relapse during this follow-up period, were interviewed monthly regarding life events. As hypothesized, for relapsing patients, a significantly higher number of independent life events (those not the result of symptomatology or personal influence) occurred in the month preceding relapse. This increase was apparent relative to either the analogous month of a "nonrelapse" period in the same patient or the average number of independent events per month during a 1-year standardized medication period for nonrelapsing patients. The methodological advances of this design as well as the consistency of these findings with those of previous retrospective studies supports the hypothesis that life events may sometimes "trigger" schizophrenic episodes.     

The role of childhood abuse and neglect in the sensitization to stressful life events in adolescent depression

This study examined the role of childhood abuse and neglect in sensitizing adolescents to the effects of proximal stressful life events in a cross-sectional sample of 103 depressed and nondepressed adolescents. Consistent with hypotheses, adolescents with a history of childhood abuse and/or neglect reported a lower level of threat of stressful life events prior to episode onset than that reported by those without. This effect was specific to those on their 1st episode of depression and was specific to independent events (i.e., stressors outside of adolescents' control). Further, this effect was robust when controlling for level of chronic difficulties, which was higher in those with childhood abuse and/or neglect. The authors suggest that childhood abuse and/or neglect may be an important risk factor that sensitizes individuals to the effects of acute independent life events.     

Skin conductance responses as predictor of emotional responses to stressful life events

Preferential preattentive processing towards threat has been proposed to play a casual role in the development of anxiety, mainly because it reliably predicts emotional responding to stressful events. However, in the investigation of the predictive value of preferential preattentive processing towards threat, the emotional Stroop task has exclusively being used. This study was designed to prospectively investigate the predictive value of skin conductance reactivity in response to masked (i.e., preattentively perceived) threatening pictures on emotional responding following stressful life events. To collect skin conductance data, the picture perception task was administered to 136 police recruits due to enroll into active duty within 2-4 months. To assess psychological distress following emotionally stressful life events, the impact of event scale were administered approximately 24 months later. Controlling for trait anxiety, analyses indicated that enhanced skin conductance reactivity in response to masked threatening pictures (relative to neutrals) was a strong predictor of emotional responding to stressful life events. This finding support preferential preattentive processing towards threat as a relatively independent factor predictive of emotional responding.     

Effects of stressful life events on human brain structure: a longitudinal voxel-based morphometry study

Although stressful life events (SLEs) have been associated with an increased risk of illness and mental disorder, their impact on brain anatomy remains poorly understood. Using a longitudinal design, we tested the hypothesis that SLEs are significantly associated with changes in gray matter volume (GMV) in brain regions previously implicated in post-traumatic stress disorder (PTSD) in a group of clinically healthy adults. Magnetic resonance imaging was used to acquire an anatomical scan from 26 subjects (13 males and 13 females; mean age ± SD: 25.2 ± 4.3 years), with no psychiatric diagnosis, at two time points with a 3-month interval. Voxel-based morphometry was used to examine an association between SLEs and gray matter changes during this period. The number of SLEs was associated with a decrease in GMV in the anterior cingulate, hippocampus, and parahippocampal gyrus (p < 0.001). In contrast, there were no areas where the number of SLEs was associated with an increase in GMV. These results provide evidence that, in adults with no formal psychiatric diagnosis, SLEs are associated with GMV decreases in a subset of regions implicated in PTSD, and that these alterations can be observed within a period as short as 3 months.     

The interaction of stressful life events and chronic strains on community mental health

One of the possible adaptive costs of coping with stress is diminished capacity to respond to subsequent adaptive demands. This paper examined the complex interplay between major life events and one source of chronic strain. Residents of the greater Los Angeles metropolitan area exposed to higher levels of smog, who had also experienced a recent stressful life event, exhibited poorer mental health than those exposed to pollution who had not experienced a recent stressful life event. There were, however, no direct effects of smog levels on mental health. These patterns of results were replicated in both a cross-sectional and a longitudinal study. The interplay of psychosocial vulnerability and environmental conditions is discussed.     

Problems of recall and misclassification with checklist methods of measuring stressful life events

The prevalent use of life event category checklists to facilitate event recall may be one reason that previous studies find that life events play only a small and ambiguous role in the development of health problems. In this study, 136 persons with temporomandibular pain disorder syndrome (TMPDS) and 131 healthy controls reported the occurrence of life events in 10 monthly interviews, using an event category checklist. At the end of the study, they reported retrospectively and in detail about life events over the previous monthly periods. Only one quarter of the event categories appeared in both the monthly interviews and retrospective report for the same period. Detailed analyses revealed problems of inaccuracy inherent in checklists that exacerbate problems of recall. The findings indicate that checklist category approaches should not be used when the goal is to understand the role of stress in adverse health outcomes. Suggestions are made about more adequate methods.     

Coping and adaptation to facial pain in contrast to other stressful life events

This article investigates whether coping with chronic pain influences adaptation to other negative life events using data on Temporomandibular Pain and Dysfunction Syndrome (TMPDS) patients (N = 99) and nonpatient controls (N = 98). It is found that cases cope very differently with pain than with other stressful events and that cases and controls do not differ on coping with nonpain events, with 2 exceptions. Cases view nonfateful events as more outside their control and they have more negative changes in usual activities following negative events. This excess of negative change is associated with greater demoralization and physical exhaustion. It is concluded that coping with repeated pain episodes leaves cases vulnerable to stressful events. Alternative interpretations, especially those involving the role of preexisting personality differences, are discussed.     

Autobiographical memory for stressful events: the role of autobiographical memory in posttraumatic stress disorder

To provide the three-way comparisons needed to test existing theories, we compared (1) most-stressful memories to other memories and (2) involuntary to voluntary memories (3) in 75 community dwelling adults with and 42 without a current diagnosis of posttraumatic stress disorder (PTSD). Each rated their three most-stressful, three most-positive, seven most-important and 15 word-cued autobiographical memories, and completed tests of personality and mood. Involuntary memories were then recorded and rated as they occurred for 2 weeks. Standard mechanisms of cognition and affect applied to extreme events accounted for the properties of stressful memories. Involuntary memories had greater emotional intensity than voluntary memories, but were not more frequently related to traumatic events. The emotional intensity, rehearsal, and centrality to the life story of both voluntary and involuntary memories, rather than incoherence of voluntary traumatic memories and enhanced availability of involuntary traumatic memories, were the properties of autobiographical memories associated with PTSD.     

Children's vulnerability to stressful life events in mothers' eyes: Effects of gender and parental experiences

Although the professional literature indicates greater vulnerability to stress among boys than girls, research on stereotypes and gender typing in socialization offers indirect evidence of a contrary belief among parents. In order to assess sex differences in vulnerability directly, 80 Israeli middle-class mothers of elementary school children were asked to predict the difficulty that low- and high-stress life events would pose for child protagonists in eight vignettes. Sex of child was manipulated by gender label denotation. Results indicated that mothers of boys predicted greater child difficulties with stress than mothers of girls. They also predicted that boys would have more difficulty than girls, a sex difference that did not appear among mothers of girls. The results suggest that maternal perceptions of sex differences in vulnerability are influenced by observation of their own children under stress. Further, professional opinion and lay wisdom as to actual male vulnerability are not necessarily at loggerheads.     

Flexible coping responses to severe acute respiratory syndrome-related and daily life stressful events

Based on the theoretical framework of coping flexibility, the present study examined the coping flexibility of university students in response to severe acute respiratory syndrome (SARS)-related and daily life stressful events. The Coping Flexibility Questionnaire was used to investigate 93 university students' coping responses toward 10 SARS-related stressful events and 10 daily life stressful events that generally occur among university students. Results showed that the patterns of coping flexibility were different for the two types of stressful events. The flexible and the active-inflexible patterns were most commonly found in coping with daily life stressful events. By contrast, the passive-inconsistent pattern was dominant when coping with daily life stressful events. Moreover, participants showed lower discriminating ability to situation controllability, and displayed poorer strategy-situation fit to cope with SARS-related events than with daily life stressful events. The theoretical and practical implications of this study are discussed.     

Social relationships,stressful life events,and self-reported physical health: Genetic and environmental influences

Abstract

This study investigates how the associations between self-reported health, stressful life events, and social relationships are mediated by genetic and environmental influences and how much of the variance in health is in common with variation in these psychosocial factors. The analyses are based on questionnaire data from 576 pairs of twins reared apart and twins reared together. The data revealed that for men environmental influences were solely important for variation in the psychosocial measures and were the primary mediators of the relationship with health. For women, on the other hand, a substantial portion of the variance in the psychosocial factors was due to genetic influences and these influences also contributed to the bulk of the correlations with health. The gender differences for the relationships and their mediation indicate that what should be regarded as a psychosocial factor of importance for health might differ between genders.     

Religiousness and depression: evidence for a main effect and the moderating influence of stressful life events

The association between religiousness and depressive symptoms was examined with meta-analytic methods across 147 independent investigations (N = 98,975). Across all studies, the correlation between religiousness and depressive symptoms was -.096, indicating that greater religiousness is mildly associated with fewer symptoms. The results were not moderated by gender, age, or ethnicity, but the religiousness-depression association was stronger in studies involving people who were undergoing stress due to recent life events. The results were also moderated by the type of measure of religiousness used in the study, with extrinsic religious orientation and negative religious coping (e.g., avoiding difficulties through religious activities, blaming God for difficulties) associated with higher levels of depressive symptoms, the opposite direction of the overall findings.
