Emotion regulation and mood brightening in daily life vary with depressive symptom levels

Naturalistic studies of emotional reactivity in depression have repeatedly found larger decreases in negative affect (NA) among depressed individuals in response to daily positive events. This so-called mood-brightening (MB) effect represents a theoretical and empirical oddity. The current study is a secondary analysis investigating whether the MB effect is moderated by spontaneous use of emotion regulation strategies, which have been implicated in the maintenance and modulation of NA in prior work. Participants (N?=?95) representing a large spectrum of depressive symptom severity reported their experiences of NA and the occurrence of positive events in daily life over the course of seven days using the experience sampling method. Our findings replicate and build upon those of prior studies relating to the MB effect in the following ways: (1) we observed the MB effect for specific negative emotions of sadness, anger, anxiety; and (2) we found evidence that the MB effect is moderated by spontaneous use of rumination, distraction, and expressive suppression, which have been shown to enhance or dampen NA. The role of emotion regulation strategies in daily emotional reactivity to pleasant events is discussed.     

生活事件对初中生抑郁的影响:自尊和反刍思维的链式中介作用

为了探讨生活事件、自尊、反刍思维和初中生抑郁之间的关系,研究采用青少年生活事件量表、自尊量表、反刍思维量表和儿童抑郁量表对684名初中生进行调查。结果显示：（1）生活事件与初中生抑郁呈显著正相关;（2）自尊和反刍思维在生活事件和初中生抑郁间起链式中介作用。生活事件不仅是触发初中生抑郁的重要外部因素,而且生活事件还会通过影响自尊和经由反刍思维对初中生抑郁产生间接作用。因此,减少和避免生活事件对初中生心理的冲击,增强其自尊水平,调整其负性认知方式是改善和预防初中生抑郁的重要途径。     

Depression and resilience mediate the relationship between traumatic life events and ill physical health: results from a population study

We set out to investigate the mediating roles of depression, resilience, smoking, and alcohol use, in the relationship between potentially traumatic life events and objective and subjective, physical and mental health in a single study. A face-to-face, population-based survey was conducted in Hong Kong (N = 1147). Information on health conditions and traumatic life events was obtained, and participants completed measures of subjective physical and mental health, depression, and resilience. Smoking and drinking were not significant mediators of the relationship between life events and both objective and subjective health. Depressive symptomatology was found to mediate the relationship between life threatening illness and subjective physical health, the relationship between abuse (physical and sexual) and subjective mental health, and the relationship between the death of a parent/partner and subjective mental health. Resilience was found to mediate the relationships between multiple traumatic life events and subjective physical and mental health. Our results indicate that psychological factors rather than biological are important mediators of the relationship between life events exposure and health. Our findings provide evidence that depressive symptomatology has a mediating role only in the case of specific potentially traumatic life events and that resilience is only a critical factor in the face of exposure to multiple traumatic events, rather than single events. Our results also indicate that behavioural factors, such as smoking and drinking, are not significant mediators of the relationship between life events and health.     

Differential Influence of Social Support in Emerging Adulthood Across Sources of Support and Profiles of Interpersonal and Non-Interpersonal Potentially Traumatic Experiences

Social support is protective against the negative effects of trauma, yet how these effects vary across sources of support and patterns of trauma exposure has not been examined. High co-occurrence exists among different types of trauma across domains and ages, yielding patterns of trauma exposure that may affect social support. This study identified profiles of potentially traumatic events (PTEs) experienced by 252 college students and examined the relationships between social support and mental health across these profiles. Five profiles emerged: “Non-Interpersonal Trauma Exposure,” “Adult Intimate Partner Violence,” “Poly-trauma Exposure,” “Low Trauma Exposure,” and “Childhood Family Violence.” The link between social support and adjustment differed across profiles. Family support was valuable for promoting resilience across patterns of PTEs. Friend and romantic partner support were related to lower mental health problems. Support from family and friends is particularly valuable in the context of adult intimate partner violence and childhood family violence.     

Suspects' consistency in statements concerning two events when different question formats are used

Lie detection research has typically focused on reports about a single event. However, in many forensic and security contexts, suspects are likely to report on several events, some of them may be untruthful. This presents interviewers with the challenge of detecting which reports are true and which are not. Varying question format in a second interview, we examined differences in liars' and truth‐tellers' statement consistency about two events. One hundred and fifty participants viewed a meeting in which a noncritical and a critical event were discussed. Truth‐tellers were instructed to be honest in their reports about both events, whereas liars had to lie about the critical event. In the first interview, all participants provided a free recall account. In a second interview, participants either gave another free recall account or responded to specific questions presented sequentially (concerning one event at a time) or nonsequentially (concerning both events simultaneously). Liars' accounts featured fewer repetitions than truth‐tellers for both events, particularly in response to questions presented in nonsequential order. The implications for the use of this question format 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 recollective qualities of adolescents’ and adults’ narratives about a long-ago tornado

The recollective qualities of autobiographical memory are thought to develop over the course of the first two decades of life. We used a 9-year follow-up test of recall of a devastating tornado and of non-tornado-related events from before and after the storm, to compare the recollective qualities of adolescents’ (n?=?20, ages 11 years, 11 months to 20 years, 8 months) and adults’ (n?=?14) autobiographical memories. At the time of the tornado, half of the adolescents had been younger than age 6. Nine years after the event, all participants provided evidence that they recall the event of the tornado. Adults also had high levels of recall of the non-tornado-related events. Adolescents recalled proportionally fewer non-tornado-related events; adolescents younger than 6 at the time of the events recalled the fewest non-tornado-related events. Relative to adolescents, adults produced longer narratives. With narrative length controlled, there were few differences in the recollective qualities of adolescents’ and adults’ narrative reports, especially in the case of the tornado; the recollective qualities were stronger among adolescents older at the time of the events. Overall, participants in both age groups provided evidence of the qualities of recollection that are characteristic of autobiographical memory.     

Impact of age-relevant goals on future thinking in younger and older adults

This study investigated how personal goals influence age differences in episodic future thinking. Research suggests that personal goals change with age and like autobiographical memory, future thinking is thought to be organised and impacted by personal goals. It was hypothesised that cueing older adults with age-relevant goals should modulate age differences in episodic details and may also influence phenomenological characteristics of imagined scenarios. Healthy younger and older adults completed the Future Thinking Interview [Addis, D. R., Wong, A. T., & Schacter, D. L. (2008). Age-related changes in the episodic simulation of future events. Psychological Science, 19(1), 33–41. doi:10.1111/j.1467-9280.2008.02043.x] adapted to activate age-appropriate goals. Narratives were scored with an established protocol to obtain objective measures of episodic and semantic details. Subjective features such as emotionality and personal significance showed age differences as a function of goal domain while other features (e.g., vividness) were unaffected. However, consistent with prior reports, older adults produced fewer episodic details than younger adults and this was not modulated by goal domain. The results do not indicate that goal activation affects level of episodic detail. With respect to phenomenological aspects of future thinking, however, younger adults show more sensitivity to goal activation, compared with older adults.     

心理时间旅行的方向与事件情绪效价对任务自信的影响

时间是认识和定义自我的框架之一。本研究采用两个实验,探讨心理时间旅行对任务自信的影响。实验1采用自由回忆或想象过去、未来事件的操纵,结果发现：事件情绪效价影响任务自信,时间方向以事件情绪效价为中介间接影响任务自信,想象的未来事件比回忆的过去事件更积极,进而引发更高任务自信。实验2采用平衡回忆或想象事件的情绪效价的操纵,使效价与时间方向的作用相分离,结果发现：时间方向不影响任务自信,想象事件的情绪效价对任务自信的作用受到时间方向的调节。回忆过去事件时,效价不影响任务自信;而想象未来事件时,事件效价越积极,任务自信越高。对于时间旅行中的积极事件,时间旅行的方向不影响任务自信;而对于消极事件,想象未来所引发的任务自信低于回忆过去。结论：时间旅行的方向与想象事件的情绪效价共同作用于任务自信。
