初中生生活事件、即时通讯与孤独感之间的关系

个体使用互联网对其心理与行为的影响一直是研究者关注的焦点,同时互联网世界是丰富多彩的,不同的互联网服务对使用者的影响是不同的。该研究采用问卷法抽取北京市两所中学初一、初二年级学生进行调查,目的是考察初中生生活事件、即时通讯服务使用偏好与孤独感之间的关系。结果表明:生活事件带来的主观压力能够显著正向预测孤独感;即时通讯能够显著负向预测孤独感;客观压力不能够预测孤独感,但是它可以通过即时通讯间接地影响个体的孤独感水平。从结果中可以看到互联网的使用对个体的发展不全是消极的,即时通讯服务的使用能够缓解生活事件对个体产生的消极影响,对个体起到一定的保护作用。     

Life Stress and Major Depression

ABSTRACT— People have long believed that adversity and stress contribute to emotional problems in general and to depression in particular. A considerable body of research has supported this intuition, documenting a consistent association between major stressful life events and the onset of clinical depression. However, most individuals under stress do not become depressed, sometimes depression develops without prior stress, and distinguishing psychological distress from major depression can be diagnostically challenging. In varying forms and degrees, life stress may play multiple roles in relation to major depression. In this article, we outline the opportunities and obstacles associated with conceptualizing depression from a life-stress perspective and discuss the implications for future research.     

Life events,social support and depression in haemodialysis patients

This study examined the effects of life events and social support on depression in 200 dialysis patients. The instruments used included the Beck Depression Inventory, a modified version of Sarason's Life Experiences Survey and a Social Support Inventory (SSI) constructed by the authors. The SSI consisted of five quantitative measures and three measures of perceived social support. These measures were found to be internally consistent and stable over time. Results showed that clinically depressed dialysis patients reported fewer positive life events and appraised life events more negatively than non‐depressed patients. The total number of life events and the number of negative life events were not found to differentiate between depressed and non‐depressed patients. With regard to social support variables, results showed that depressed patients reported less frequent actual contact and telephone contact with others and perceived a smaller amount and less availability of social support and less satisfaction with perceived social support along the functional dimensions of emotional, informational, appraisal and instrumental support and social companionship. The results were found to provide support for a main effect model of social support and not for a buffering model. Copyright © 1999 John Wiley & Sons, Ltd.

Broadening (and narrowing) the scope of brand relationships

The Attachment–Aversion Relationship Model proposed by Park, Eisingerich, and Park represents the latest in a series of attempts to expand, refine, and validate the increasingly popular concept of brand relationships. We find much value in the effort. We suggest, however, that researchers should avoid indiscriminate use of the term and focus on identifying the unique contribution that the notion of brand relationships can make to theory and practice. We also note how the present model could be expanded to achieve this objective.     

Stressful Life Events: A Revision and Update of the Social Readjustment Rating Scale

The widely used and cited Social Readjustment Rating Scale developed by Holmes and Rahe (1967) was comprehensively revised and updated. The new instrument, containing 51 major life events, was administered to a national sample of 5000. Respondents were asked to rate the stressfulness of each life event on a 1–100 scale. Completed surveys were returned by 3122 individuals (62.4%). Responses were analyzed using repeated measures MANOVA and profile analysis. Major results included: (a) statistically and practically significant differences in mean ratings for the 51 life events; (b) five overlapping themes in the top 20 rated life events—death and dying, healthcare, crime and the criminal justice system, financial/economic issues, and family-related issues; and (c) an amazing level of agreement concerning perceived life event stressfulness, regardless of gender, age, or income level.     

Negative life events and symptoms of depression and anxiety: stress causation and/or stress generation

Background and Objectives: Stressful life events are known to contribute to development of depression; however, it is possible this link is bidirectional. The present study examined whether such stress generation effects are greater than the effects of stressful life events on depression, and whether stress generation is also evident with anxiety. Design: Participants were two large age cohorts (N = 732 aged 44 years; N = 705 aged 63 years) from the West of Scotland Twenty-07 study. Methods: Stressful life events, depression, and anxiety symptoms were measured twice five years apart. Cross-lagged panel analysis examined the mutual influences of stressful life events on depression and on anxiety over time. Results: Life events predicted later depressive symptomatology (p = .01), but the depression predicting life events relationship was less strong (p = .06), whereas earlier anxiety predicted life events five years later (p = .001). There was evidence of sex differences in the extent to which life events predicted later anxiety. Conclusions: This study provides evidence of stress causation for depression and weaker evidence for stress generation. In contrast, there was strong evidence of stress generation for anxiety but weaker evidence for stress causation, and that differed for men and women.     

Detecting and constructing meaning in life events

Three studies examined the meaning ascribed to events varying in intensity and valence and how meaning detection and construction relate to the experience of meaning in life events. In Study 1, participants were more likely to expect meaning to emerge from major life events particularly if they are negative, while trivial events were expected to be meaningful if they were positive. Study 2 showed that constructed meaning was more likely to occur in response to negative events while detected meaning was more likely to be associated with positive events. Study 3 showed that this ‘match’ between valence and meaning strategy predicted enhanced experience of meaning in those events. These studies suggest that the more subtle experience of meaning detection may provide a way to understand the meaning that emerges from positive events and experiences.     

Life‐events and post‐traumatic stress in a sample of English adolescents

The aim of the present study was to investigate the lifetime prevalence of negative life‐events and their association with post‐traumatic stress in English adolescents. Of the 427 adolescents surveyed, 360 (84%) endorsed at least one negative event. Respondents were asked to complete the Impact of Event Scale (IES: Horowitz, Wilner and Alvarez, 1979) for each event that they endorsed. For boys, highest levels of post‐traumatic stress were found in those who had experience of a ‘family member with a drink or drugs problem’, followed by ‘parental separation or divorce’, ‘life threat to family member’, and ‘life‐threat to self ’. For girls, highest levels of post‐traumatic stress were found in those who had experienced ‘attack or physical assault to self ’, followed by ‘family member with drink or drugs problem’, ‘parental separation or divorce’, and ‘life threat to family member’. These data suggest that moderate levels of post‐traumatic stress are present in around one fifth of adolescents who have experienced one of these events and that community levels of post‐traumatic stress in adolescents may be higher than previously thought.

Assessment and treatment of self-control with aversive events

Self-control can be defined as choosing a smaller, immediate aversive event over a larger, delayed aversive event (e.g., flossing daily instead of risking major dental problems later). Children with developmental disabilities have been found to respond impulsively when given the choice between aversive events that differ based on magnitude and difficulty. However, qualitative differences between events may also impact aversiveness. This study attempted to replicate and extend prior research by (i) empirically identifying a hierarchy of qualitatively different aversive tasks for three individuals with developmental disabilities by evaluating their average latency to escape responses when presented with each task, (ii) assessing baseline levels of self-control (i.e., selection of immediate, low-aversive tasks over delayed, high-aversive tasks), and (iii) implementing an empirically validated treatment (i.e., adding a delay to both tasks). Each participant initially made impulsive choices, but self-control increased following treatment.     

Posttraumatic Stress Symptoms and Stressful Life Events Predict the Long-term Adjustment of Survivors of Childhood Cancer and Their Mothers

Objectives: To examine prospectively the impact of posttraumatic stress symptoms (PTSS) in response to childhood cancer and treatment on general adjustment while accounting for the role of other stressful life events and appraisal of life threat and treatment intensity. Methods: As part of a larger study assessing PTSS, 56 childhood cancer survivors, aged 8 to 18, and 65 mothers completed self-report measures of PTSS and appraisal of the intensity and life threat associated with cancer treatment at time 1 and self-report measures of stressful life events and general adjustment at time 2 (approximately 18 months after time 1). Results: For child survivors and their mothers, posttraumatic stress at time 1 significantly predicted general adjustment at time 2, over and above the significant contribution of lifetime stressful events. The life events variable did not function as a mediator in the association of PTSS and general adjustment. Conclusions: Trauma responses to childhood cancer and its treatment have implications for the long-term adaptation of children and their families. Early signs and symptoms of posttraumatic stress and stressful life experiences require early assessment and intervention.     

Extreme malleability of preferences: Absolute preference sign changes under uncertainty

Malleability of preferences is a central tenet of behavioral decision theory. How malleable preferences really are, however, is a topic of debate. Do preference reversals imply preference construction? We argue that to claim preferences are construed, a demonstration of more extreme preference malleability than simple preference reversals is required: absolute preference sign changes within participants. If respondents value a prospect positively in 1 condition but negatively in a different condition, preferences cannot be considered stable. Such absolute preference sign changes are possible under uncertainty. In 2 incentive‐compatible experiments, we found participants were willing to pay to take part in a gamble and also demanded to be compensated to take part in a subsequent gamble with identical outcomes and probabilities. Such absolute preference sign changes within participants led to simultaneous risk aversion and risk seeking for the same risky prospect, suggesting that, at least in the domain of risky decisions, consumers' preferences are indeed malleable and construed.     

Some determinants of changes in preference over time

Results of longitudinal studies suggest that the stability of preferences varies across individuals, although it is unclear what variables account for these differences. We extended this work by conducting periodic assessments of preference for leisure activities over 3 to 6 months with 10 adults with developmental disabilities. Although previous research has collectively shown that preferences identified via repeated assessment are highly variable, our results showed that preferences were relatively stable for the majority (80%) of participants. In an attempt to identify some environmental determinants of shifts in preference, we provided extended daily access to high-preference items (preference-weakening manipulation) and paired access to low-preference items with social and edible putative reinforcers during brief sessions (preference-strengthening manipulation). Preference assessments continued over the course of these manipulations with 2 participants. Results showed that changes in preference across time could be produced systematically and suggest that naturally occurring changes in establishing operations or conditioning histories contribute to temporal shifts in preference. Implications for preference assessments, reinforcer usage, and planned attempts to change preferences are discussed.     

The role of stressful life events on the cortisol reactivity patterns of breast cancer survivors

Objective: Atypical patterns of cortisol secretion following an acute stressor have been commonly reported in breast cancer survivors. Stressful life events have been associated with blunted acute cortisol levels in other populations. The purpose of this study was to explore the role of stressful life events on cortisol secretion patterns of breast cancer survivors following an acute stressor.

Design: The Trier Social Stress (TSST) was used to elicit a moderate stress response in breast cancer survivors (n = 19) and a control group (n = 17). Saliva samples were collected before, during and after the TSST to provide cortisol concentrations. During recovery, we recorded the frequency and subjective impact of stressful life events in the past year using the Life Experience Survey.

Results: Simple regressions analyses were performed; results suggest no group differences between the total number of stressful life events and their subjective impact. However, the total number of stressful life events as well as their subjective impact correlated negatively with the peak cortisol concentration in breast cancer survivors.

Conclusions: The cumulative effect of stressful life events, positive and negative, may impact the endocrine stress system of breast cancer survivors more so than that of women with no history of cancer.     

The relationship between stress,hemispheric preference and decision making among managers

Abstract

Previous studies have shown important effects of stress on decision making (DM). In addition, individuals differ in their relative activation of the left and right hemispheres (hemispheric preference; HP), with possible implications for DM. This study tested the relationship between stress, HP and their interaction, with DM in managers. We included a sample of 114 managers from Israel, Italy and France. Stress was inversely and significantly related to DM thoroughness (r=?.333), left-HP (r=?.24) and was positively correlated with instinctiveness DM (r=.25; all p<.05). Importantly, a stress×HP interaction accounted for an additional and significant 9% of the variance in thoroughness, beyond their main effects, nationality and gender. In this interaction, only in right HP managers, but not in left HP managers, stress was inversely correlated with thoroughness. A stress×HP interaction was not found for instinctiveness. Theoretically, our results advise investigating both situational (stress) and personal or biological (HP) factors in the job stress field. Practically, it can guide stress specialists to whom to provide scarce counseling resources of stress management, to improve workers’ DM and well-being.     

Life events and psychological well-being in old age

Abstract

Although life event research has burgeoned in recent years, little attention has been paid to the prevalence of events among the elderly or their relationship to psychological well-being. This paper presents data from a three-wave longitudinal study of community elderly in Aberdeen. Negative life events were highly prevalent among both survivors [N=349) and non-survivors [N=108], but the relatively small differences between the groups indicate that attrition does not seriously affect longitudinal findings. Longitudinal analysis of survivors' data was performed using LISREL and yielded a model with a goodness of fit index of 0.918, demonstrating a close fit between the data and the model. The model parameters indicate that those in poor psychological state were more likely to report serious non-health events than health events, although the latter were more likely than the former to result in a decline in psychological well-being, even after prior psychological state was taken into account. While elderly people with low social integration experienced more severe reactions to life events in the short term than those with high social integration, there were no significant long term effects, even for those reporting highly stressful events. There was no evidence of a sub-group of elderly people lacked into a cycle of serious life events. However life events were not random occurrences; serious health events were more often reported by those with low education while women and those in lower social classes were more likely to report serious non-health events. Overall, long term disruption, directly attributable to life events, was minimal when viewed within the context of the community elderly's stable psychological state.     

Understanding the richness of brand relationships: Research dialogue on brands as intentional agents

This essay offers some perspectives on Kervyn et al.'s insightful research on brand relationships and the role of perceived intentions and ability. After briefly discussing the importance of brand knowledge and functionality in understanding the diversity of brand relationships, some other antecedents and consequences of brand relationships are reviewed. Three antecedents of corporate credibility — expertise, trust, and likability — are suggested as another means to differentiate how consumers view different brands. Brand resonance — an intense, active loyalty relationship — is also suggested as an important outcome of brand relationships. The essay concludes by noting that any concept as complex as brand relationships lends itself to multiple concepts, perspectives, and analysis.     

Life events and internalizing problems among Chinese school children: An examination of the cognitive diathesis model

This study examined the cognitive diathesis model for child internalizing problems among 459 Chinese elementary school children in grades four to six. Life events were associated with beliefs about external control and threat perception bias, both of which were related to child internalizing problems. The relation of life events to internalizing problems was partially mediated by threat perception bias measured by ambiguous situation task. The main findings indicate that the cognitive diathesis theory for child internalizing problems might be applicable to Chinese children. This study contributes to the theoretical understanding of the internalizing problems of Chinese children, which can lead to use of more effective treatments.
