Stressful life events: Their past and present status

The present paper reviews some of the major fields of interest in current life event research. Some theoretical issues are examined: for example, generality versus specificity of life event effects, the time span encompassed by life event research, development of life change scales, and perceptual concensus concerning the severity of life changes. Methodological problems concerned with causal or correlational conclusions and illness behaviour are also discussed. Models of the life event stress process are mentioned with reference to ‘resistance resources’. Finally the field of life event research has been integrated into McGrath’s conceptualization of stress research.     

Exposure Duration as a Confounding Methodological Factor in Projective Testing

Summary: Exposure duration has been found to have a strong impact on the affective value attributed to a variety of stimuli. The purpose of the study reported here was to examine the impact of this variable in projective testing, and im particular in the affective value subjects attribute to the TAT cards. Using 34 undergraduate students, a linear decrease in pleasantness was found as a function of exposure duration. Factors leading to variation in exposure dur'ation might therefore be confounded with the interpretations made of a subject's protocol. It was suggested that the time a subject views a projective test stinlulus should be controlled in the administration.     

The perception of women's status in Israel as a social problem

This study examines the perception of the status of women in Israel as a social problem, its cognitive structure and its correlates. The 994 respondents included a sample of university students, nurses, and female army officers. In general, the results suggest that feminist issues are perceived as less severe than most other social problems and that men perceive feminist issues as significantly less severe than do women. Factor analyses indicate that men and women think about social problems differently and that women have a broader more integrated conception of sex inequality. Sex, religiosity, education, and occupational context were all found to be significant predictors of perceptions of women's issues as social problems.     

Preventive behaviour and health status among the elderly

Abstract

The research describes the range of preventive health behaviours undertaken by the elderly, investigates the dimensionality of preventive health behaviour, and explores the relationship between preventive health behaviour, self-assessed and medically assessed health status. Previous research has relied mainly on self-reports of health status. Data from medical examinations and interviews with 115 elderly individuals (aged 65–75) indicated that most elderly persons performed some intentional preventive health practices, as well as a broad range of normative preventive health practices. Particular clusters of preventive health behaviour emerged when the data were subjected to cluster analysis. A short index consisting of five personal preventive health behaviours found in other studies to have a protective effect on long-term health was found to have a low to moderate correlation with the medical and self-assessments of health status employed in the study. These findings indicate particular types of preventive health behaviour of importance for health promotion programmes with the elderly.     

Perceptions of stressful life events as turning points are associated with self-rated health and psychological distress

Abstract

We test the hypothesis that changes in physical and psychological health are associated with construals of stressful life events. At two points in time, approximately 10 years apart, participants (n=1038) rated their physical health and psychological distress. At the second assessment, participants also reported their most stressful life event since the first assessment and indicated whether they considered the event a turning point and/or lesson learned. Lower self-ratings of health and higher ratings of psychological distress, controlling for baseline health and distress, and relevant demographic factors, were associated with perceiving the stressful life event as a turning point, particularly a negative turning point. The two health measures were primarily unrelated to lessons learned. How individuals construe the most stressful events in their lives are associated with changes in self-rated health and distress.     

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.     

Some effects of positive life events on community mental health

Measures of positive and negative events were derived from a life-event inventory to test the predictions of an equilibrium model and a positive mental health model of psychological well-being. These measures were related to indicators of individual and community well-being with data obtained through a household survey of 454 residents. Residents who reported more negative events also reported more psychological distress and less positive adjustment. Positive events were associated with reports of positive adjustment. An analysis of census tract scores on life events revealed that the relative absence of positive events in census tracts was associated with higher service utilization rates to the community mental health center serving those tracts. The number of negative events was unrelated to service rates for census tracts but was related to several demographic indicators of well-being.     

Skinner and a solution to the problem of inner events

Skinner's treatment of inner states has been criticized not only by cognitivists but also by people who are close to behaviorist views. In particular, critics have argued that because of the limited conceptual resources of his scientific framework, Skinner cannot account for "mental" phenomena such as the qualitative character of feelings, conscious contents, or states of awareness. The present paper claims that these criticisms are mistaken. By paying careful attention to Skinner's strict physicalist position and by employing a consistent physicalist terminology, it can be shown that Skinner is able to account for the phenomena in question.     

Inventorying stressful life events as risk factors for psychopathology: Toward resolution of the problem of intracategory variability

An explosion of research on life events has occurred since the publication of the Holmes and Rahe checklist in 1967. Despite criticism, especially of their use in research on psychopathology, such economical inventories have remained dominant. Most of the problems of reliability and validity with traditional inventories can be traced to the intracategory variability of actual events reported in their broad checklist categories. The purposes of this review are, first, to examine how this problem has been addressed within the tradition of economical checklist approaches; second, to determine how it has been dealt with by far less widely used and far less economical labor-intensive interview and narrative-rating approaches; and, third, to assess the prospects for relatively economical, as well as reliable and valid, solutions.     

Rumination as a common mechanism relating depressive risk factors to depression

Rumination was examined as a potential common mechanism linking risk factors with depression. Initially nondepressed individuals (N = 137) were assessed for presence of a ruminative response style and 4 other hypothesized risk factors for depression. They were followed for 2.5 years. Negative cognitive styles, self-criticism, dependency, neediness, and history of past depression were all significantly associated with rumination. Rumination mediated the predictive relationships of all risk factors except dependency with the number of prospective Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; American Psychiatric Association, 1987) major depressive episodes (MDEs; definite and subthreshold) during the follow-up period. In contrast, private self-consciousness did not mediate any relationships between risk factors and subsequent MDEs. Thus, rumination, as a special kind of self-focus, may act as a general proximal mechanism through which other vulnerability factors affect depression.     

Subjective well-being and adaptation to life events: a meta-analysis

Previous research has shown that major life events can have short- and long-term effects on subjective well-being (SWB). The present meta-analysis examines (a) whether life events have different effects on affective and cognitive well-being and (b) how the rate of adaptation varies across different life events. Longitudinal data from 188 publications (313 samples, N = 65,911) were integrated to describe the reaction and adaptation to 4 family events (marriage, divorce, bereavement, childbirth) and 4 work events (unemployment, reemployment, retirement, relocation/migration). The findings show that life events have very different effects on affective and cognitive well-being and that for most events the effects of life events on cognitive well-being are stronger and more consistent across samples. Different life events differ in their effects on SWB, but these effects are not a function of the alleged desirability of events. The results are discussed with respect to their theoretical implications, and recommendations for future studies on adaptation are given.     

Locus of control,life stress,and social networks: Gender differences in the health status of the elderly

A sample of community-based older adults were interviewed and given a questionnaire in order to examine the effects of stress, social support, and locus of control on two measures of health: the number of actual symptoms and self-ratings of health. Subjects were 83% white, 63% female, and represented middle- and working-class backgrounds. All variables showed association with symptom levels, and for men, both locus of control and friend support networks predicted subjective ratings of health even after controlling for the level of symptomatology. Moreover, an internal locus of control was found to buffer the deleterious effect of symptoms of physical illness on self-rated health. The results suggest that a supportive network and a sense of control build confidence in one's capacity to cope both with external stressors and with sickness itself, but these factors are stronger influences for males than for females.     

Patterns of adolescent involvement in problem behaviors: Relationship to self-efficacy,social competence,and life events

Using a sample of 556 adolescents from a suburban community, patterns of various adolescent problem behaviors (e.g., delinquent behavior, smoking, use of alcohol or drugs) and their links to self-efficacy, social competence, and life events were examined. Cluster analysis was conducted to identify four subgroups of adolescents who showed distinct patterns of problem behaviors. These clusters were compared on the measures of self-efficacy, social competence, and life events. Overall results suggest there are meaningful links between adolescents’ problem behavior patterns and self-efficacy, the amount and quality of participation in various after school activities, and life events. For example, a subgroup of adolescents who showed uniformly low prevalence of all problem behaviors reported more positive academic self-efficacy, more active participation in sports and nonsports activities, more positive life events, and fewer negative events than adolescents who were involved in multiple problem behaviors. Implications for prevention and future research on adolescent problem behaviors are discussed.     

Measuring health status and quality of life in HIV and AIDS

Abstract

HIV can diminish quality of life profoundly, and it is important to understand and measure such effects of HIV and its treatments Although the term quality of life is commonly used, “health status” more accurately describes dimensions that are directly health related and that may be affected by traditional interventions. There is a substantial literature on general health status measurement, and several of the most established measures have been applied or adapted for use in HIV infected populations These measures include the Medical Outcomes Study health ratings, the Quality of Well-Being scale, and the Sickness Impact Profile. Cancer-specific measures such as the EORTC Quality of Life Core Questionnaire and the CARES have also been adapted. In the last three years, health status measures for HIV have been completed by several thousand patients, and have generally proved to be reliable and valid indicators of relevant clinical differences such as disease stage, numbers of symptoms, and other psychometic measures of disability and distress. Health status measures were included in a few completed clinical trials, and are being incorporated in a growing number of antiretroviral and antimicrobial studies. Health status measures provide the best way to evaluate psychosocial interventions directly aimed at improving patients' quality of life. Although challenges remain in further developing health status measures for HIV disease and in applying them, measurement of these concepts has proved to be both technically and operationally feasible. Measures of health status and quality of life can play an important role in the evaluation of clinical treatments in research studies, directing clinical treatment, assessing changes in health care delivery, and planning health care services.     

Perceived self-other differences in life events and mental health among Mexicans and Americans

The social context of reported stressful life events was examined as a determinant of psychiatric symptoms in four cultural groups: Anglo-Americans (n = 132), Mexican-Americans (n = 108), Mexicans in El Paso (n = 90), and Mexican nationals (n = 133). The perceived difference between life events experienced by the self and spouse or by the self and significant others constituted preliminary operational definitions of the social context of life events. Ten Psychiatric Epidemiology Research Interview (PERI) psychiatric symptom scales as well as a suicidal tendency scale and a hopelessness index constituted the measures of the dependent variables. The potential predictive value of the social contextual measures of life-event stress for mental health variables was generally supported by the findings. Results indicated a rank ordering of predicted effects, with Mexican nationals most susceptible to the psychological effects of the social context of life events and Anglo-Americans least susceptible.     

Daily versus major life events as predictors of symptom frequency: a replication study

Predictions of physical symptomatology by daily life events and by major life events were compared, replicating and expanding work reported by DeLongis, Coyne, Dakof, Folkman, & Lazarus (1982). Analyses of daily, prospective data collected on 79 married men for 90 days demonstrated that daily, undesirable events were better predictors of symptom frequencies than either past, major life events or daily, desirable events. These results, similar to those found by DeLongis et al. (1982), were further explored by examining "healthy" subjects versus subjects with prior medical conditions. Undesirable daily events were a much stronger predictor of physical symptoms in the healthy group than in the prior medical conditions group.
