创伤后成长:概念、影响因素、与心理健康的关系

创伤后成长是指在与生活中具有创伤性质的事件或情境进行抗争后体验到的心理方面的正性变化。许多因素,包括人口统计学、创伤事件的特征、人格与认知、社会支持与应对方式等都对创伤后成长有影响。创伤后成长与心理健康的关系未有一致的结论,两者间关系的不一致有四种可能的解释。未来研究应注意创伤后成长与相关概念的区别,探寻确证成长有效性的新证据和新方法。     

Does stress-related growth involve constructive changes in coping intentions?

The theorized link between stress-related growth (SRG) and enhanced coping intentions was examined in 91 young adults. Participants reported their most stressful event in the past year, how they coped with it, their perceived SRG from this event, and how they would intend to cope should this same event happen again. In general, SRG was unrelated to intended changes in coping. Participants then read three vignettes describing stressful events. For each, they imagined that it was currently occurring and reported their coping plans. Whereas SRG was positively related to some adaptive coping plans, it was also related to several maladaptive strategies, inconsistent with coping enhancement. Overall, findings suggest that SRG might represent retrospective positive reappraisals vs. growth, as has been shown for the related construct of posttraumatic growth (PTG). Implications for the validity of SRG and directions for future research are discussed.     

Predictors of Growth in the Aftermath of Traumatic Events: The Role of Personal Growth Initiative

The current study examined the role of personal growth initiative (PGI) in predicting posttraumatic growth and posttraumatic stress, and the extent to which rumination styles explain these relations among 286 college students. As predicted, results showed that the cognitive component of PGI negatively predicted posttraumatic stress. Also, there was a significant positive indirect effect of behavioral PGI on posttraumatic growth through deliberate rumination. However, contrary to our hypothesis, there were also significant positive indirect effects of behavioral PGI on posttraumatic stress through intrusive and deliberate rumination. The current study creates new insights on the application of PGI in trauma research.     

Three Futures: Nightmare,Diversion, Vision

Possible futures can, for simplicity, be reduced to three broad options: “Business-as-usual economic growth” (“Nightmare”), “Green economic growth” (“Diversion”), and “Ecological sustainability” (“Vision”). We critically discuss the feasibility and sustainability of each. We find that the Nightmare option will eventually be undermined by ecological deterioration and rising resource scarcity, while the Diversion option, we argue, is doomed to failure. The Vision option is for us the only viable future, but requires unprecedented socioeconomic changes. Regardless of path, either Earth biophysical changes, or socioeconomic changes—or possibly both—will be unprecedented. Hence, predicting the future, never easy, will become much harder.     

Individual and Collective Posttraumatic Growth in Victims of Natural Disasters: A Multidimensional Perspective

This study set out to incorporate the collective dimensions of posttraumatic growth and examined the construct and predictive validity of The Individual and Collective Posttraumatic Growth Scale (ICPTGS). Participants were 332 volunteers who had experienced the earthquake on February 27, 2010, in Chile. Analysis allowed us to confirm a multidimensional structure composed of four dimensions: individual, spiritual, communal growth, and societal growth. Additionally, we identified association among ICPTGS, perceived emotional impact, and social well-being. This study emphasizes that positive changes resulting from the exposure to collective disasters can be perceived also at the collective or community level.     

Finding character strengths through loss: An extension of Peterson and Seligman (2003)

People can experience positive changes even in the midst of adversity and loss. We investigated character strengths following three recent shooting tragedies. Using an Internet database of respondents to the Values in Action Inventory of Strengths (VIA-IS), we compared responses from three groups of participants (N?=?31,429) within close proximity of each event: those who completed it eight months prior to the event, and one month and two months after. Results suggested that for one of the events, participants who completed the VIA-IS after the event showed slightly different levels of self-reported character strengths compared to participants who completed the VIA-IS before the event, with some mean levels higher and others lower. The observed differences in character strengths were inconsistent across follow-up periods, and effect sizes were small (d values from –0.13 to 0.15). These findings raise questions about whether and how tragedies might catalyze differences in character strengths.     

The Sustainable Development Goals: a comment

The agreement on Sustainable Development Goals (SDGs) is a tremendous achievement. The goals represent an advance on the Millennium Development Goals (MDGs), by aiming to eliminate poverty, by including an equality goal and by bringing sustainability into the agenda. Nonetheless, three outstanding issues remain. First, national ownership is likely to be a problem. The centrally agreed goals need to be interpreted nationally to allow for national priorities and circumstances and to secure national commitment to them. Secondly, the goals are silent on the underlying economic structures needed to realize some of the goals, particularly of reducing inequality. Existing economic structures and policies are likely to result in a move away from achievement of this goal. Thirdly, most important, there is not true integration of the sustainability and economic goals. The goal of promoting economic growth needs to be seriously qualified for middle and high income countries, if the sustainability objectives – particularly on carbon emissions – are to be realized. This requires either that economic growth should only be promoted if sustainability can be assured, or that growth is redefined as ‘green growth’ so that promoting economic growth and achieving sustainability become consistent.     

Fitting cross-classification table data to models when observations are subject to classification error

Individuals are classified in a cross-classification table where two behavioral observations on each individual determine the classification. The problem is to test certain structural models assumed to underlie the cross-classified observations. A minimum chi-square test procedure is proposed.

The Hard Issues of Life

In pastoral counseling, the practitioner and client face the most difficult human problems. An authentic encounter and subsequent connection with one's fundamental Being often occurs, creating a direct existential knowing of what is. Because there are no directions or steps in a protocol to follow in this process, it is helpful for the client to reframe his/her existential search for Being as a Rite of Passage, comprising three distinct, but not separate stages—the separation phase, the initiation phase, and the return or integration phase. Such a process permits the individual a realization of what is through his/her own life circumstances, as a meaningful progression of spiritual growth.decorated Vietnam combat veteran and a marriage, family, and child counselor specializing in treatment of PTSD     

多阶段混合增长模型的方法及研究现状

多阶段混合增长模型(PGMM)可对发展过程中的阶段性及群体异质性特征进行分析,在能力发展、行为发展及干预、临床心理等研究领域应用广泛。PGMM可在结构方程模型和随机系数模型框架下定义,通常使用基于EM算法的极大似然估计和基于马尔科夫链蒙特卡洛模拟的贝叶斯推断两种方法进行参数估计。样本量、测量时间点数、潜在类别距离等因素对模型及参数估计有显著影响。未来应加强PGMM与其它增长模型的比较研究;在相同或不同的模型框架下研究数据特征、类别属性等对参数估计方法的影响。     

Screens across the pond: Findings from longitudinal screen time research in the US and UK

Digital media are increasingly pervasive in the lives of young children. This increase in the availability of digital media might have long-run implications for child development; however, it is too soon to definitively conclude the direction of effects. In part due to this lack of certainty, leading health organizations have chosen to make different recommendations to parents of young children: Many international health organizations (e.g., the American Academy of Pediatrics, World Health Organization) recommend very young children be limited to under one hour of screen time daily, whereas others (e.g., Royal College of Paediatrics and Child Health) have intentionally opted not to make recommendations about specific limits. These guidelines might contribute to parents in different countries making meaningfully different choices about children’s use of digital media. Using a sample of N = 303 families recruited in Cambridgeshire, England and New York City prior to the birth of couples’ first child, we explore predictors of digital media use across the first two years of life. Data were collected when children were 4, 14, and 24 months of age. Results of latent growth curve analyses show that generally, children spend more time engaging with digital media as they grow older; however, growth mixture models reveal most children fit into one of two classes: One group of children (High Media Users; 52.2 %) engages with a substantial amount of digital media, whereas the other (Low Media Users; 48.8 %) engages with relatively little. Children in the US were approximately 30 % more likely to be in the Low Media Users group and there were no differences in group membership on the basis of parents’ psychosocial wellbeing. While these differences could be due to a number of factors, these findings may reflect the power of pediatric recommendations.     

Prospective writing: Randomized controlled trial of an intervention for facilitating growth after adversity

Little is known about how posttraumatic growth (PTG) can be fostered and controversy surrounds how it is best measured. We designed and tested an intervention, prospective writing, to facilitate PTG by encouraging people to explore new possibilities after adversity. Adults (N = 188) with recent adverse experiences were randomly assigned to do prospective writing, factual writing, or no writing weekly for one month. PTG was assessed with both retrospective and current-standing measures. Hierarchical linear modeling and response profile analysis were used to assess the intervention’s impact, and latent growth curve modeling was used to test mediation. Prospective writing participants showed the greatest gains in PTG as assessed by the current-standing measure, but did not reliably show greater retrospective PTG than controls. Although large effect sizes for the mediation paths suggested that engagement with new possibilities may be a plausible mechanism, this result fell short of statistical significance. Prospection-based interventions merit further investigation.     

Cross-Cultural Challenges to the Construct “Posttraumatic Growth”

Responses of individuals to traumatic events are varied. Traumatic events can lead to positive transformations that are known as posttraumatic growth (PTG). Most of the empirical studies of PTG have been addressed from a Western perspective. Theoretically, the concept appears to be cross-culturally valid, but there has been a fundamental deficiency in operationalizing the concept in regard to cultures that are non-Western. Cultural elements play an important role in influencing the behavior of individuals in the aftermath of trauma. Hence, it is important to conceptualize and measure PTG in the framework of the culture to which the individual belongs. The effects of culture come from both the immediate culture (proximal) and the broader (distal) sources that impact the nature of rumination, cognitive strategies, and the process of growth. This paper addresses various cross-cultural challenges to the construct PTG such as emic versus etic perspectives on PTG, proximate and distal influences of culture on PTG, specific cultural influences on rumination, cognitive strategies, and growth, cultural bias inherent in theories of PTG, and measurement issues of PTG across cultures.     

Journeys With People Who Have Dementia: Connecting and Finding Meaning in the Journey

This article begins with a reflective journey with one person who was diagnosed with early onset dementia. It then turns to reflect on the subsequent journey of research with other people who have dementia and where they find meaning in life, through the process of spiritual reminiscence. The article views dementia through a theological lens that sees those who have dementia as people made in God’s image and the implications this has for the lives of those living with dementia and those who care for them. One of the important findings from research conducted in the small group process was that meaning was almost synonymous with relationship and connectedness for participants, just as it is for people who don’t have dementia.     

Loneliness as Moderator Between Trauma and Posttraumatic Growth

This study investigated the association between loneliness, trauma symptomatology, and posttraumatic growth (PTG) in undergraduate students (N = 362). The study also explored whether loneliness moderated the relationship between experiences of trauma and PTG. The results demonstrated that both loneliness and trauma symptoms predicted levels of PTG, and loneliness moderated the relationship between trauma and PTG. Limitations, directions for future research, and implications for counseling are discussed.

Examining the effects of grade retention on student reading performance: A longitudinal study

Grade retention is an intervention that has received increasing scrutiny as policies, practices, and results of research diverge. This longitudinal study examines the reading growth trajectories of students (n = 147) from first- through eighth-grade. Hierarchical Linear Modeling (HLM) analytic procedures provide unique insights regarding the relative reading growth curves among retained students, similarly achieving but promoted students, and a random sample of students. The results revealed that retained students did not experience a benefit in their growth rate (relative to either the preceding year, or to similarly performing but promoted students), and made less progress compared to the randomly selected group of students. While consistent with the extant empirical evidence failing to support the effectiveness of grade retention, these findings warrant careful consideration given both the longitudinal design and the analytic procedures.
